解题思路
1. 研究类说明文核心解题方法
1. 结构预判法：快速把握文章脉络：在开始阅读前，先在心理上预设文章会遵循 背景过程发现
“
→
→
→
结论意义
→
” 的基本结构。带着这个地图去阅读，能帮你：
“
”
快速将具体内容归位，理解其在不同部分的作用。
当题目考查特定环节时（如研究目的、研究方法），能迅速定位到原文的相应部分。
2. 首尾定位法：锁定研究目的与核心结论
研究目的：通常出现在文章开头部分。关注作者为了引出研究而描述的现象、提出的问题或指出的现
有知识的空白。这些内容直接揭示了为何研究。
“
”
核心结论：通常位于文章结尾部分。研究的最终结论往往是全文主旨的体现，也是解答主旨大意题的
关键。
3. 细节锚定法：精准捕捉研究过程与发现：研究过程与发现是细节题的高发区。解题时务必：
精准定位：根据题目关键词（如研究方法名称、特定数据等）回到原文找到对应句子。
仔细比对：将选项与原文进行细致对比，注意选项是否在范围、程度、因果关系上对原文进行了偷换
或曲解。
4. 语境释义法：攻克术语与词义猜测：研究中不可避免会出现专业术语或生词。遇到时：
寻找上下文线索：密切关注该词前后的定义、解释、举例或对比关系。
利用逻辑关系：通过分析句子内部的因果、转折、并列等逻辑关系来推断词义。
5. 逻辑推理法：推断研究意义与作者意图：对于研究意义、影响或作者写作目的等推断题：
基于结论，合理推演：答案不会明说，需要你基于研究的最终结论，向前推演一步，思考其所以然
“
”
——即这项发现可能如何应用、对现有认知或实践会产生什么影响。
辨别观点与事实：严格区分文中客观陈述的研究发现（事实）和作者或他人基于事实发表的评论与
“
”
“
看法（观点），这对推理至关重要。
”
6. 主旨提炼法：概括研究核心：为文章选择最佳标题或概括主旨时：
覆盖全局：正确选项必须能涵盖研究的整体内容，而不仅仅是某个细节。
突出核心：标题应精准指向研究的核心对象与最重要发现。
警惕陷阱：注意排除那些以偏概全、过于笼统或偏离重点的选项。
2. 事实类说明文核心解题方法
1. 精准定位法：攻克细节与特征题：此类题型要求直接回到原文寻找答案。
题干定位：抓住题干中的关键名词（如 cats' meowing, solar still equipment）和位置信息（如 from the
first paragraph），迅速锁定原文相关句。
比对筛选：将选项与原文信息进行逐字逐句的仔细比对。注意识别选项的同义转述，并排除无中生有、
偷换概念或扩大/缩小范围的干扰项。
2. 逻辑延伸法：推断功能与用途：解答此类题目需要在事实基础上进行一步合理的逻辑推演。
寻找功能词：定位并勾画描述事物能力或特性的词句（如 can monitor..., is used to...）。
推导现实价值：基于其特性，思考拥有这种能力，在现实中能解决什么问题或带来什么好处？。例
“
”
如，一个能监控牛群健康的机器人，其用途自然是保障牛群健康而非直接治疗病牛。
“
”
“
”
3. 步骤重建法：理清顺序与过程：对于涉及流程或构造的说明文，可视化方法非常有效。
勾画标志词：在阅读时，注意 first, then, next, finally 等序列信号词。
流程图解：在草稿纸上快速画出简单的步骤流程图或事物构造图。这能直观地帮你理清顺序，应对如
the last step 或 drops come from... 这类问题。
4. 语境分析法：破解词义与指代：这是阅读理解的核心微技能，绝不依赖词汇量猜测。
指代题：向前寻找该短语或代词所指代的那个具体名词或概念。答案通常就在前一句或前几句中。
词义题：紧密分析生词或短语所在的上下文，寻找定义、解释、举例、比较或对比等线索来推断其含
义。
5. 核心聚焦法：概括主旨与标题：这是对全文内容的顶层概括。
主题句筛查：重点审查文章开头、结尾以及各段首句，这些地方通常包含中心思想。
综合概括：确保正确选项能够全面覆盖文章的说明对象及其最核心的特征或价值。
排除陷阱：果断排除以下选项：
以偏概全（只涉及某个细节）。
过于笼统（缺乏文章具体内容）。
偏离主旨（与文章核心说明对象无关）。
3. 新事物说明文核心解题方法
1. 定义定位法：精准把握新事物本质
首段聚焦：新事物的基本定义、核心功能或设计目标通常在文章开头（尤其是第一段）明确给出。
信号词捕捉：关注如 is designed to..., aims to..., the main function/purpose is... 等明确表达功能目的的信
号词。
解题关键：准确识别并定位这些核心句，就能直接解答关于新事物是什么的问题。
“
”
2. 对比分析法：厘清优势与存在理由
寻找参照物：在文中明确找出被对比的旧事物或传统方法。
“
”
“
”
识别问题与优势：定位旧模式面临的 痛点
“
” （如 labor shortage, low efficiency）和新事物带来的 亮
“
点” （如 higher accuracy, cost-saving）。
解题关键：新事物的优势总是相对于旧事物的不足而存在。找到这个对比关系，就找到了答题的钥匙。
3. 过程可视法：理解应用与运作机制
勾画步骤与组件：对于涉及流程或构造的说明，在阅读时随手圈出 by using..., through..., the first step 等
表示方法或顺序的词。
构建逻辑链：在脑中或草稿上简单梳理出“通过什么技术/方法
实现了什么功能
达到了何种效
→
→
果的逻辑链条。
”
解题关键：区分监控与治疗等不同性质的功能，确保对运作机制的理解精准到位。
“
”
“
”
4. 辩证思考法：评估局限与发展前景
主动预判：阅读时主动思考这项新技术可能有什么缺点？
“
”
定位批评意见：直接寻找表达疑虑、批评或指出不足的词句，通常位于介绍完新事物基本功能后的段
落中，并伴有 however, some people concern..., the limitation is... 等信号词。
解题关键：认识到局限性是新事物说明文的常见组成部分，不必因其存在而否定新事物的整体价值
“
”
。
5. 立场推断法：辨析观点与作者态度
划分阵营：在文中标记出不同人物及其观点，如支持者（
“
”
Michael Kelsey）和怀疑者（
“
”
Peter
Bonds）。
分析论证强度：对比双方论据的说服力，并关注文章结构的安排（如先写反对意见再写支持意见，往
往暗示作者倾向于后者）。
解题关键：作者的态度虽未必明说，但可通过其给予不同观点的篇幅、论证逻辑的强弱以及材料的组
织方式推断出来。总体而言，介绍新事物的文章基调通常是谨慎乐观的。

【例1-1】（25-26 高三·山东德州·期中）
Candles on a birthday cake mark calendar age, but they miss the hidden clock inside our bodies. Harvard
Medical School now reports that each of us also has a “biological age” for every major organ, and these ages vary
sharply even among people born in the same year.
Using blood samples from 44,498 UK Biobank volunteers aged 40-70, the team measured nearly 3,000 proteins.
About fifteen percent of those proteins originate in a single organ, allowing an algorithm (算法) to assign an “organ
age” to the brain, heart, kidneys and eight other systems. Participants were then followed for up to seventeen years.
The results translate numbers into risks. One-third of the volunteers had at least one organ whose protein signature
lay more than 1.5 standard deviations (标准差) from the age-adjusted average, a gap linked to sharply higher disease
risks. Most striking was the brain. “The brain is the gatekeeper of longevity,” said senior author Tony Wyss-Coray,
“If you’ve got an old brain, you have an increased likelihood of death.” An “extremely aged” brain raised the
fifteen-year risk of death by 182% and multiplied the chance of an Alzheimer’s diagnosis compared with an “extremely
youthful” brain.
Because organ age is readable years before symptoms appear, the same blood test could guide prevention.
Wyss-Coray envisions pairing the test with detailed lifestyle and medication records to see whether already-approved
drugs can rewind the biological clock of a high-risk organ. “Today you go to the doctor because something aches,”
he noted, “We’re trying to shift from sick care to health care.”
Unfortunately, the technology is currently available only for research, but Wyss-Coray has started two
companies, Teal Omics and Vero Bioscience, approved by Harvard to turn the findings into commercial drug searches
and a consumer test. “A streamlined panel focusing on the brain, heart and immune system could reach clinics within
two to three years,” he predicts, “and the cost will come down as we focus on fewer key organs.”
1． Why are birthday cake candles mentioned in paragraph 1?
A．To issue a warning.
B．To draw a contrast.
C．To highlight a custom.
D．To make a prediction.
2． What can we learn from the research?
A．Severe brain aging increases death risk.
B．Organs age at the same rate individually.
C．Volunteers’ diets affect protein signatures.
D．Young brains ensure Alzheimer’s prevention.
3． Which practice matches the study in paragraph 3?
A．Treating a heart attack when it happens.
B．Repairing functions of organs at high risk.
C．Tracking daily exercise before health checks.
D．Using brain age tests to prevent early diseases.
4． What is Wyss-Coray’s prediction mainly about?
A．Potential clinical application.
B．Consumers’ possible reaction.
C．More researchers’ engagement.
D．Research technology innovation.
【答案】1．B 2．A 3．D 4．A
【导语】本文是一篇说明文。文章主要讲述了哈佛医学院研究发现人体器官有生物年龄，且与疾病风险

”
15 年内的死亡风险增加182%，并使阿尔茨海默病的诊断几率成倍增
加)”可知，严重的脑部衰老会增加死亡风险。故选A。
3．推理判断题。根据第三段中“Because organ age is readable years before symptoms appear, the same blood test
could guide prevention.(由于器官年龄在症状出现前几年就可以被检测出来，同样的血液检测可以指导预防)”
以及第二段中“An “extremely aged” brain raised the fifteen-year risk of death by 182% and multiplied the chance
of an Alzheimer’s diagnosis compared with an “extremely youthful” brain.(与极其年轻的大脑相比，极其衰老
“
”
“

的大脑会使15 年内的死亡风险增加182%，并使阿尔茨海默病的诊断几率成倍增加)”可知，使用大脑年龄
测试来预防早期疾病与第三段中的研究相匹配。故选D。
4．细节理解题。根据最后一段中““A streamlined panel focusing on the brain, heart and immune system could
reach clinics within two to three years,” he predicts, “and the cost will come down as we focus on fewer key
organs.”(“一个专注于大脑、心脏和免疫系统的流线型面板可以在两到三年内到达诊所，他预测，随着我
”
“
们专注于更少的关键器官，成本将会下降。”)”可知，Wyss-Coray 的预测主要是关于潜在的临床应用。故选
A。
【例1-2】（25-26 高三上·天津咸水沽一中&天津一百中·期中）
In our daily lives, we often hear about the benefits of exercise for our physical health. But have you ever
wondered about its effect on our memory? Well, a recent study from University College London has some interesting
findings.
The researchers discovered that 30 minutes of moderate to vigorous physical activity, along with at least six
hours of sleep at night, could potentially lead to an improvement in cognitive performance the following day. This
means that activities like cycling to work or going for a brisk walk in the morning might not only make you feel good
for the day but also have a positive impact on your memory the next day.
Previous studies on the short-term effects of physical activity were mostly done in laboratories and focused on
short time frames. However, this new study observed the real-life physical activity of 76 adults aged 50 — 83, who
did not have cognitive impairment or dementia. These participants wore an accelerometer for eight days to track their
sleep and physical activity. They also took simple online cognitive tests daily to measure their attention, memory, and
processing speed.
The results showed that each 30-minute increase in physical activity corresponded to a 2% — 5% increase in
episodic and working memory scores the next day. But when sleep data was considered, only the working memory
score improvement remained significant. The study also found that more sedentary behavior was associated with a
drop in working memory scores, while getting enough sleep led to better scores in episodic memory and other
aspects.
Despite these findings, the study had its limitations. The participants were generally well-educated and had
good health and high levels of daily physical activity, which might not represent the entire population. Also, the exact
reason why exercise affects memory the next day is still unclear, as the benefits from neurotransmitters are thought
to be short-lived.
In conclusion, while we still have more to learn, this study suggests that staying active and getting enough
sleep could be beneficial for our brain health and memory. So, let’s put on our running shoes and hit the sack early
to give our brains a boost!(362)
1． What did the University College London study find?
A．Any amount of exercise improves memory immediately.
B．Thirty minutes of exercise and proper sleep may enhance next-day cognitive ability.
C．Only intense exercise affects memory.
D．Sleep has no connection to memory improvement.
2． How was this study different from previous ones?
A．It involved a larger number of participants.
B．It focused only on the long-term effects.
C．It only studied younger people.
D．It was based on real-life activity tracking.
3． What were the participants asked to do in the study?
A．Exercise for a fixed time every day.
B．Wear a device and do cognitive tests.
C．Change their diet drastically.
D．Avoid all sedentary activities.
4． What are the limitations of the study?
A．The participants were all athletes.
B．It didn’t consider the role of diet.
C．The participants had specific characteristics.
D．It was too expensive to conduct.
5． What is the main purpose of the last paragraph?
A．To suggest practical applications of the findings.
B．To criticize the study's limitations.
C．To propose directions for future research.
D．To explain the physiological mechanisms.

Every human being is longing for connection. From birth, social interactions shape our brain architecture, and
this need becomes especially intense in adolescence — a stage when identity is forming and peer relationships hold
huge weight. It’s no surprise, then, that even brief social isolation (孤独) can deeply change how teenagers think,
feel, and behave. A recent study by the University of Cambridge sheds new light on just how sensitive young people
are to loneliness.
The research involved 40 mentally healthy adolescents aged 16 to 19 with typical social connection levels. On
two separate days, each participant spent 3-4 hours alone before completing computer tasks measuring reward-

seeking motivation (e.g., reacting to social interaction images or money-earning games). The critical difference: one
day, they had no social contact at all (no phones, no Internet); the other, they could use devices for virtual interaction.
The results were striking: after total isolation, teens showed far stronger drive to seek rewards—staring longer at
happy social scenes and excelling (胜出) more in money-earning games. Virtual socializing softened this shift, though
it still caused a drop in positive mood.
This study adds nuance (细微差别) to the social media debate. While digital platforms are often blamed for
rising teen loneliness, they acted as a buffer here, easing loneliness and reducing intense reward-seeking. Yet they’re
no cure-all — Professor Sarah-Jayne Blakemore notes virtual connection brings risks like harmful content or addiction.
Its value depends on context: it helps when in-person bonds are scarce but can never replace their richness.
Global teen loneliness has doubled in a decade, driven by academic pressure, changing family structures,
economic instability, and more — not just social media. Loneliness ties to depression, anxiety, and even long-term
cardiovascular risks.
The study’s core lesson: social interaction is a basic human need, not a luxury. For caregivers, educators, and
society, creating environments where teens build genuine in-person connections is essential for healthy development.
Loneliness, ultimately, is a signal — seek community. Answering that call doesn’t just ease teens’ present pain; it lays
the groundwork for their lifelong well-being.
1． What difference was found between the two test days in the study?
A．Teens used more devices on the day with total isolation.
B．Positive mood dropped only on the day of no social contact.
C．Total isolation led to stronger reward-seeking motivation in teens.
D．Virtual interaction made teens perform worse in money-earning games.
2． What can we infer about virtual socializing from the text?
A．It has both positive effects and potential risks for teens.
B．It is the main cause of increasing teen loneliness globally.
C．It can completely replace in-person connections for teens.
D．It eliminates the need for teens to seek real-world rewards.
3． What does the author think of teens’ healthy development??
A．Virtual socializing is sufficient.
B．Loneliness is self-overcomable.
C．Academic pressure is the biggest barrier.
D．In-person social connections are essential.
4． Which of the following is the best title for the text?
A．The Dangers of Social Media for adolescents
B．A Study on Teenagers’ Love for Virtual Interaction
C．The Profound Impact of Loneliness on adolescents
D．How to Reduce Teenagers’ Loneliness in Digital Times

Autism (自闭症) should not be viewed as a single condition with a unified underlying cause, according to
scientists who found that those diagnosed early in childhood typically have a distinct genetic profile to those diagnosed
later.
“The term ‘autism’ likely describes multiple conditions,” said Dr. Varun Warrier, from Cambridge’s department
of psychiatry, senior author of the research. “For the first time, we have found that earlier and later diagnosed autism
have different underlying biological and developmental profiles.” While autism is defined as having challenges with
social communication, sensory processing and restrictive behaviours, there is huge variability in how these difficulties
present themselves between individuals. Scientists have been investigating whether subgrouping the population based
on shared features or pathways could make the study of autism more manageable.
The international study, published in Nature, based on genetic data from more than 45,000 autistic people in
Europe and the US, found that the underlying genetic profiles differed greatly between those diagnosed with autism
earlier and later in life, with only limited overlap. It showed that the average genetic profile of later-diagnosed autism
is closer to that of ADHD (a mental disease), as well as to mental health conditions such as depression and PTSD,
than it is to autism diagnosed in early childhood.
Those diagnosed in early childhood, typically before six years old, were more likely to show behavioural
difficulties from early childhood, including difficulty in walking fast and interpreting hand gestures, as well as
problems with social interaction, but remain stable. Those diagnosed with autism later, typically after the age of 10,
were more likely to experience increasing social and behavioural difficulties during adolescence and also had an
increased likelihood of mental health conditions such as depression.
The scientists are not advocating a move towards two diagnostic categories, saying that this could be unhelpful
for the many who fall somewhere in the middle.
Prof Uta Frith, a professor at University College London, who was not involved in the research, said,“It makes
me hopeful that even more subgroups will come to light, and each will find an appropriate diagnostic label. It is time
to realize that’ autism’ has become a ragbag (大杂烩) of different conditions.”
1． What is typical of autism?
A．Inability to behave controllably.
B．Tendency to talk too much.
C．Eagerness for public attention.
D．Difficulty in relieving loneliness.
2． What does the underlined word “overlap” in paragraph 3 probably mean?
A．Contrast.
B．Commonality.
C．Variation.
D．Stability.
3． What is paragraph 4 mainly about?
A．The relationship between age and autism.
B．Mental health risks in adolescents with autism.
C．Social interaction difficulties in autism patients.
D．Differences in autism features based on diagnosis age.
4． What can be inferred from Prof Uta Frith’s words?
A．Autism is a consequence of mixed factors.
B．Different categories of autism have been properly labeled.
C．More diagnostic categories of autism are to be discovered.
D．The research should be improved with more detailed data.

【例2-1】（25-26 高三·山东省实验中学·期中）
What if your friends are going through life-or-death situations in the family? Social exchange theory would
suggest that you’d better drop them because they’re not providing as many benefits to you as they could. Different
from the exchange-based relationship, real-life experiences with these situations might be the opposite: These are the
times when many people are most likely to support their friends.
A recent research backs this up. “When surveyed about what they want in a friend, people didn’t place a high
value on paying back any debts — something highly valued from a social exchange perspective”. “Instead, they
considered other traits — such as loyalty, reliability and being there in times of need — to be much more important”,
Charlie Kirk, leader of the investigation added. The essence of friendship may be what is called risk-pooling where
our ancient ancestors support each other to survive life challenges.
According to the survey by The Human Generosity Project, a cross-disciplinary research collaboration, this
kind of friendship can still be found across societies, from “kere kere” in Fiji to “tomor marang” among the Ik in
Uganda. Similarly, the Maasai, a native group in Kenya and Tanzania who rely on cattle herds to make their living,
cultivate friends who help them when they are in need, with no expectation about paying each other back. Just like
the “neighboring” network rooted in southern Arizona and New Mexico, farmers help their neighbors with
unpredictable challenges such as an accident, injury or illness.
“What all these findings suggest is that friendship is less about the exchange of favors and more about being
there for each other when unforeseeable disaster strikes. Friendship seems more like an insurance plan designed to
kick in when you need it most rather than a system of balanced exchange”, says Charlie.
In a world of growing uncertainty, cultivating risk-pooling friendships and striving to be a good partner yourself
may help you build resilience. Our ancestors survived with the help of this kind of relationship; our future may depend
on them too.
1． How does the author present the issue in the first paragraph?
A．By defining a concept.
B．By making a comparison.
C．By analyzing reasons.
D．By giving examples.
2． Which may be valued according to social exchange theory?
A．A good grasp of maths.
B．A timely period of company.
C．Balanced cost and benefit.
D．Distinguished survival skills.
3． What does Paragraph 3 mainly talk about?
A．The cases of risk-pooling friendship.
B．The reasons for risk-pooling friendship.
C．The mechanism of exchange-based friendship.
D．The possible logic of exchange-based relationship.
4． What is the author’s attitude toward Charlie Kirk’s research findings?
A．Dismissive.
B．Approving.
C．Neutral. D．Doubtful.

【例2-2】（25-26 高三上·河北秦皇岛山海关一中·月考）
My grandmother was an extraordinary woman who single-handedly raised three children while working
multiple jobs and volunteering in her community. I loved her for her warm heart and belief in nature. But there’s one
particular thing that I didn’t see eye-to-eye with her: her firm belief that everything used to be much better. My
grandmother criticized everything from modern food options to modern equipment like computers. Once, she threw
out a calculator because she thought it unnecessary.
This worldview is a classic example of “declinism”, a pessimistic thinking bias leading people to believe that
things are constantly getting worse over time. It reflects an overly negative view of the current situation, and usually
goes hand in hand with tendencies to romanticize the past. Individuals with declinist views often recall positive
memories of the past while overlooking negative ones.
Negative news reporting often triggers (引起) declinism. Alarmist news stories of war, disaster, and suffering
frequently occupy TV and newspaper headlines because they’re effective in grabbing attention. With hopelessness
occupying each title page, it’s hardly surprising if people assume that things are going downhill. Once the seed of
declinism is planted, the notion is difficult to shake off. Confirmation bias can perpetuate the negative worldview
because people seek out information to confirm their ideas.
Declinism plays into humans’ rooted fear of change. Sticking with what’s known is easy. Doing things “the
way we’ve always done them” provides comfort in an uncertain world. Declinism may even have evolutionary
advantages. Pessimistic worrying about the world’s decline may motivate us to get prepared and minimize personal
risks.
To deal with declinism, factual, statistical information might go a long way. Providing objective facts about
current levels of crime, poverty, and suffering compared to past data can challenge negative worldviews. One
possibility could be to use the power of AI to provide relevant information and tailor it to address particular concerns,
supported by recent research that found chatbot (聊天机器人) dialogues to be effective for tackling misperceptions.
1． What does the author’s grandmother think of modern conveniences?
A．They are odd.

If you are a perfectionist, you are probably familiar with the feeling of wanting to get everything right. You
may struggle with handing in impressive papers, stress over joint projects, and even worry about insignificant errors
from the past.
High standards are one thing, but perfectionism is quite another. Perfectionists hold themselves to unrealistically
high standards and become self-critical if they believe they fail to meet these standards. Perfectionists are also likely to
feel shame if they experience failures, which often leads them to avoid situations where they are anxious they might
fail.
Although people see the pursuit of excellence as a good thing, on the extreme end, it might do harm. Researchers
have found that perfectionism is associated with depression, anxiety, and eating disorders. Besides, people who are
more strongly identified with perfectionist qualities have reported higher levels of overall psychological unease.

learning and growing, accepting imperfection can actually help people in the long run.
One possible alternative to perfectionism involves developing a growth mindset. Unlike those with fixed
mindsets, who see their skill levels as unchangeable, those with growth mindsets believe they can improve their
abilities by learning from their mistakes. Parents can help their children develop healthier attitudes toward failure:
praise their children for making an effort even if their results are imperfect, and help the children learn to persevere
(坚持) when mistakes happen.
Another potential alternative is to develop self-sympathy. Think about how you would respond to a friend if
he has made a major mistake. Odds are, you’d probably respond with kindness and understanding, knowing that your
friend meant well. The idea behind self-sympathy is that we should treat ourselves kindly and avoid being consumed
by negative emotions.
After all, it’s possible to make peace with perfectionism and develop a healthier way of setting goals for
yourself.

【变式2-2】（24-25 高三·广东肇庆·一模）
Nowadays, many Chinese tourists are so troubled by holiday crowds that seeking out unheralded (冷门的)
destinations has become a trend known as “reverse travel”. Aside from providing people with better travel experiences
with fewer crowds, reverse travel also meets their need for novelty and uniqueness.
A key driver of travelers heading to lesser-known cities is cost. While the Labor Day holiday saw record
numbers of domestic travelers, average spending per person remained below pre-pandemic levels according to a
report. Hotels in lesser-known cities can be five times cheaper than in Beijing or Shanghai.
The reverse travel trend has seen surging bookings in smaller cities, driven mostly by young people escaping
the crowds on Shanghai’s Nanjing Road or in Beijing’s Forbidden City. Wang Xinyu is one of them. During the Labor
Day holiday, she left for Weihai, a less famous city for traveling. “Not only can I experience the local way of life by
wandering through a park or exploring a market, but the hotel here also costs only a third of the price of Nanjing’s
downtown hotels — it’s much more cost-effective,” says Wang.
However, escaping large popular cities doesn’t guarantee better experiences. The recent virality of niche (小
众的) travel spots has revealed formerly hidden gems (宝石) to more travelers, but many small towns and rural areas
aren’t well equipped to handle the new tourist influx. Handan, a city of 9 million in Hebei Province, suffered
overcrowding during the Labor Day holiday when it was listed as the seventh most popular “niche” travel spot by
social media. Those who come with high hopes of idyllic (田园风的) breaks often instead find limited public transport,
entertainment facilities, and charm. Some even report boredom.
No destination or time is perfect. Either visitors see famous sites and face the crowds, or head off the beaten
track and endure worse accommodation and transport options. “With the crazy amount of people traveling now, you
have to let go of something if you want some peace and quiet,” says Mr. Zhai, a tourism researcher from Beijing.
1． Why does the author mention Wang Xinyu’s traveling experience?
A．To explain how to choose hotels.
B．To introduce Weihai’s scenic spots.
C．To present reverse travel’s advantages.
D．To prove young people love traveling.
2． What might have caused unpleasant reverse traveling experiences?
A．Low budget way of traveling.
B．Higher hotel costs during holidays.
C．Overcrowding in famous destinations.
D．Inadequate facilities in small destinations.
3． What might be Mr. Zhai’s attitude to traveling?
A．Travelers prefer unheralded spots.
B．Travelers need to think carefully.

Exercising has many health benefits. Soon, it could help lower your electricity bill! Instead of spending hours
charging your wearable devices, scientists from the United Kingdom have developed a nano device that generates
electricity from running energy.
The flexible nanogenerator (纳米发电机), which turns some mechanical energy into electricity, could become
as useful in creating clean energy as solar cells. A study published in Nano Energy showed it produces 1,000
milliwatts of power — a 140-fold increase over traditional 10-milliwatt nanogenerators.
“What’s really exciting is that our little device with high energy harvesting efficiency could one day rival the
power of solar panels and could be used to run anything from self-powered sensors to smart home systems that run
without ever needing a battery change,” explains Md Delowar Hussain, a researcher at the University of Surrey and
lead author of the study.
Researchers have created a new nanogenerator that collects and turns the energy from everyday movements
into electricity. It uses materials that become electrically charged when in contact. Think of how rubbing a balloon
on someone’s hair makes it stick to each other because of static electricity (静电). Instead of one electrode (电极)
passing energy by itself, the new device has a relay of workers who shift mechanical energy, like running, into
electricity. Each electrode collects a charge and then passes it on to the next electrode. The accumulating charge
creates more energy in a process known as the charge regeneration effect.
Hussain says the ultimate goal is to use these nanogenerators to capture and use energy from everyday
movements, like your morning run, mechanical vibrations, ocean waves, or opening a door. “The key innovation with
our nanogenerator is that we’ve enhanced the technology with 34 tiny energy collectors using a laser technique that
can be scaled up for manufacture to increase energy efficiency further.” Hussain says.
For now, the researchers are working on launching a company that uses nanogenerators like the one in the
study to create self-powered, harmless healthcare sensors. These devices could then expand to other sections of health
technology.

【例3-2】（25-26 高三上·四川绵阳三台中学·月考）
As bird numbers fall worldwide, scientists are using algorithm (算法)-powered apps to gather data about bird
species.
One such example is the owl project, where researchers placed more than 1,600 recorders to track where the
endangered species spends its time. But that’s a lot for a human to sort through. “There’s no way we can listen to
that— not even close, right?” says Connor Wood, a researcher leading the owl project. “We need flexible tools to
identify as many bird species as possible.”
In 2016, Connor Wood approached Stefan Kahl, a computer scientist at Chemnitz University, to help create an
algorithm that processes bird sounds recorded in the wild. Two years later, the team launched the official BirdNET
app, which allows people to upload their own recordings from various devices. The app converts a bird’s song into
an image of soundwaves known as spectrogram (声谱图). Then, the image is fed into the app’s algorithm which can
accurately show the unique frequency changes, timing, and amplitude (振幅) of a particular call. “These patterns that
the algorithms find are much more subtle and fine-grained than what any human could do,” says Kahl.
It turns out this team actually can process this flood of data—they just need a little help from BirdNET, an AI-
powered system that can identify more than 6,000 species of birds just by their calls. Wood and his team recently
used BirdNET to create the first ecosystem-wide assessment of spotted owl populations across the Sierra Nevada.
This information shows owl population trends that can boost restoration and conservation efforts.
Over the past decade, several apps have popped up that use AI to identify different bird sounds. However, like
most AI-based technology, these apps aren’t without limitations. In 2023, ecologist Pérez-Granados found that
BirdNET didn’t always register a bird’s song, and sometimes misidentified it as another species.
There are some ways to lessen these risks, including accounting for uncertainty using statistical models or
manually going through identifications to double check data. For a 2022 study, Wood and his team assessed the
accuracy of BirdNET submissions, and found their data could successfully reproduce the known migratory routes of
several North American and European birds. And more research shows AI can identify bird behaviors and distribution,
which is critical for conservation.

3D-printed heart, made using the patient’s own cells and materials, has been created in a lab.
Until now, success has been limited to printing only simple tissues without blood vessels (血管). “This is the
first time anyone has successfully printed an entire heart anywhere,” said team leader Tal Dvir.
The 3D-printed heart is only about a third the size of an actual human heart and it doesn’t actually work. But
it’s a groundbreaking step toward engineering customized (定制的) organs that can be transplanted with less risk of
rejection. Dvir noted that scientists have managed to print a 3D structure of a heart before, but not with cells or blood
vessels. The use of biological materials from a patient is key to successful engineering of tissues and organs.
Ideally, the biomaterial should possess the same biochemical and mechanical properties of the patients’ own
tissues. This way, their bodies will be less likely to reject the organ, making transplants much safer.
While the 3D-printed heart is about a third the size of a human heart, the same technology can be used to
print a normal-sized one. The team’s next step is to culture (培养) printed hearts in the lab and “teach them to behave”
like real hearts. Then, researchers plan to transplant the 3D-printed heart into lab animals.
“Our results demonstrate the potential of our approach to engineering personalized tissue and organ replacement
in the future,” Dvir said. “Maybe in 10 years, there will be organ printers in the finest hospitals around the world, and
these procedures will be conducted routinely.”
1． What can be inferred from the world’s first complete 3D-printed heart?
A．It makes organ transplants risk-free.
B．It bridges gaps in biological organ printing.
C．It solves the donor shortage for heart transplants.
D．It has the same properties as natural heart tissues.
2． What does Dvir imply about the previous 3D-printed heart structures in paragraph 3?
A．They were ready for transplant to animals.
B．They matched the size of real human hearts.
C．They lacked cell-based biological components.
D．They contained complete blood vessel networks.
3． What will Dvir’s team do in the future?
A．They will first test printed hearts on humans.
B．They will focus on curing early heart failure.
C．They will change the biological materials used.
D．They will improve the heart’s functional performance.
4． What’s Dvir’s attitude towards the 3D printing technology?
A．Positive.
B．Doubtful.
C．Negative.
D．Indifferent.

Stanford assistant professor Ruike Zhao published a groundbreaking medical breakthrough in Nature: using
a tiny 2 mm micro-robot, she increased the success rate of blood clot (血块) removal from a mere 11% to an amazing
90%, sending shockwaves through the medical world.
In modern society, about one in every dozen people may experience a blood clot in their lifetime. It is widely
known that blood clots are the leading cause of strokes and heart attacks. During treatment, the ability to quickly and
effectively restore blood flow becomes a matter of life and death.
Unfortunately, traditional mechanical methods have a low success rate. The process is like trying to pick up
broken tofu with chopsticks — not only is success unlikely, but the situation may even worsen. Blood clots may break
apart while being deformed, resulting in small pieces stuck in hard-to-reach areas.
However, Professor Zhao’s 2 mm micro-robot enters blood vessels (血管) and, using high-speed rotation (旋
转), generates forces to reduce the clot size to 5%. It’s like when you press and rub soft things, like hair, between
your hands. The force makes them stick together into a small ball. The micro-robot works similarly, using pressure
to bring the clot components together, making them easier to remove. This process requires no drugs, causes no vessel
damage, and effectively releases trapped red blood cells back into blood.
What’s astonishing is that this innovation is inspired from subway TBMs, tunnel-boring machines (盾构机).
The way tunnel-boring machines efficiently handle hard soil and rock in narrow spaces inspired the creation. This
brilliant Chinese researcher miniaturized the enormous underground machine to a size tens of thousands of times
smaller and adapted it for use in human blood vessels.
Currently, the technology has been successfully tested on pigs. While most of these studies remain in the
laboratory phase, the breakthrough itself is exciting. This technology may soon extend beyond blood clots to address
issues like kidney stones or gallstones.
1． How does the author present the breakthrough in paragraph 1?
A．By explaining a technical term.
B．By contrasting the statistics.
C．By providing the study’s background.
D．By citing an authority.
2． What is the advantage of Zhao’s micro-robot over traditional methods?
A．It generates blood more rapidly.
B．It prevents clots from forming again.
C．It is recyclable and economical.
D．It raises success rate and reduces side effects.
3． What does the author try to illustrate by mentioning TBMs?
A．The cost of medical robotics.
B．The reason behind the numerous trials.
C．The inspiration behind the innovation.
D．The importance of modern machinery.
4． What is the last paragraph about?
A．Choice of new research methods.
B．Possible direction for further study.
C．Necessity for tests on more animals.
D．Potential application of the invention.

When Sonja Detrinidad opened her online shop selling houseplants, she didn’t have high hopes for it. But the
opposite happened: She was flooded, shipping out 1,200 orders in June of 2020 alone. In the past year, Detrinidad
sent out more than 70,000 plants. Her success is just one example of increased time at home leading to an explosion
in the houseplant industry.
“Plants are in fashion right now,” says Dr. Melinda Knuth, a researcher from the University of Florida. “People
who live in plant-rich environments report a higher life satisfaction rating, ” she says. “Adding more nature to our
environment can change our mood and how we think.” Plants can improve our state of mind in a few ways but the
biggest is by decreasing our level of cortisol, the stress hormone (激素) in our body.
“Students who are around plants perform better academically than students who are in a classroom without
plants,” says Knuth. “This productivity also translates into the workplace for adults. Our study showed that there was
a 30% decrease in sick leave for people who were in plant-rich workplaces.”
If you’re among the groups of people who are enjoying the mental and physical health benefits of surrounding
yourself with plants, don’t beat yourself up if one (or a few!) doesn’t make it. “Doctors practice medicine and lawyers
practice law and you should allow yourself the practice it takes to sustain a plant. Tending to plants is an exercise in
patience and learning. Be invested in taking care of it, but if it dies, go get another one,” Detrinidad says.
1． How was Detrinidad’s business when it started?
A．It faced tough competition.
B．It suffered a great loss.
C．It got lots of financial support.
D．It went surprisingly well.
2． What is one of Knuth’s findings about plants?
A．They appeal more to students.

As new technologies take on increasingly humanlike qualities, there’s been a push to make them genderless.
“People are stereotyping (形成刻板印象) their gendered objects in very traditional ways,” says Ashley Martin, a
Stanford associate professor of organizational behavior. Removing gender from the picture altogether seems like a
simple way to fix this. Yet as Martin has found in her work, gender is one of the fundamental ways people form
connections with objects, particularly those designed with human characteristics.
In her study, Martin asked participants to rate their attachment to male, female, and genderless versions of a
digital voice assistant and a self-driving car known as “Miuu.” It was found that gender increased users’ feelings of
attachment to these devices and their interest in purchasing them. For example, participants said they would be less
likely to buy a genderless voice assistant than versions with male or female voices.
While gendering a product may be good marketing, it may also strengthen outdated or harmful ideas about
power and identity. The stereotypes commonly associated with men, such as competitiveness and dominance, are
more valued than those associated with women. These qualities, in turn, are mapped onto products that have been
assigned a gender.
Martin’s study also found that creating a genderless object was difficult. For instance, if an object’s name was
meant to sound genderless, like Miuu, participants would still assign a gender to it — they would assume Miuu was
a “he” or “she.”
Martin sees a silver lining, however: She believes that anthropomorphism (拟人化) “provides an opportunity
to change stereotypes.” When women are put into positions of leadership like running companies, it reduces negative
stereotypes about women. Similarly, anthropomorphized products could be created to take on stereotype-inconsistent
roles — a male robot that assists with nursing or a female robot that helps do calculations, for instance.
1． What is the purpose of making new technologies genderless?
A．To reduce stereotypes.
B．To meet public demand.
C．To cut production costs.
D．To encourage competition.
2． What were the participants probably asked to do in the study?
A．Design a product.
B．Respond to a survey.
C．Work as assistants.
D．Take a language test.
3． Why is it difficult to create genderless objects?
A．They cannot be mass-produced.
B．Naming them is a challenging task.
C．People assume they are unreliable.
D．Gender is rooted in people’s mind.
4． What does the last paragraph mainly talk about?
A．The quality of genderless products.
B．The upside of gendering a product.
C．The meaning of anthropomorphism.

Microplastics have become a common source of pollution across the Earth — they have settled in the deep sea
and on the Himalayas, stuck inside volcanic rocks, filled the stomachs of seabirds and even fallen in fresh Antarctic
snow. They are even appearing inside humans.
Now, new research suggests that a simple, cheap measure may significantly reduce the level of microplastics
in water from your tap (水龙头): boiling and filtering (过滤) it. In a study published Wednesday in Environmental
Science & Technology Letters, researchers from China found that boiling tap water for just five minutes — then
filtering it after it cools — could remove at least 80 percent of its microplastics.
Crucially, this process relies on the water containing enough calcium carbonate (碳酸钙) to trap the plastics.
In the study, boiling hard water containing 300 milligrams of calcium carbonate led to an almost 90 percent drop in
plastics. But in samples with less than 60 milligrams of calcium carbonate, boiling reduced the level of plastics by
just 25 percent. Additionally, the research didn’t include all types of plastics. The team focused only on three common
types — polystyrene, polyethylene and polypropylene — and they didn’t study other chemicals previously found in
water such as vinyl chloride.
Still, the findings show a potential path forward for reducing microplastic exposure — a task that’s becoming
increasingly difficult. Even bottled water, scientists found earlier this year, contains 10 to 1,000 times more
microplastics than originally thought.
Scientists are still trying to determine how harmful microplastics are — but what they do know has raised
concerns. The new study suggests boiling tap water could be a tool to limit intake. “The way they demonstrated how
microplastics were trapped through the boiling process was nice,” Caroline Gauchotte-Lindsay, an environmental
engineer of the University of Glasgow in Scotland who was not involved in the research, tells New Scientist. “We
should be looking into upgrading drinking water treatment plants so they remove microplastics.”
1． How does the author present the issue in the first paragraph?
A．By quoting an expert.
B．By defining a concept.
C．By giving examples.
D．By providing statistics.
2． What determines the effectiveness of trapping microplastics in water?

The robot, shaped like a soup can with a rounded body, stands on a wearer’s shoulder like a parrot. It can speak
fluent Anishinaabemowin, an Indigenous (土著的) language spoken by the Anishinaabe nation of North America.
Danielle Boyer, a 24-year-old Anishinaabe roboticist, created the “Skobot” to communicate in endangered Indigenous
languages. By enabling young speakers to practice with an engaging partner, she aims to keep these languages alive
despite the growing dominance of English.
New AI technologies are revolutionizing the way we approach language preservation. Most AI translation
systems require vast training data for accuracy, and models for high-resource languages like English and Spanish are
typically trained on millions of parallel sentence pairs. However, Indigenous languages often have little public data,
posing significant challenges for standard translation methods. To address this, Jared Coleman, a computer scientist
at Loyola Marymount University, developed a tool that instructs a large language model in the grammar and vocabulary
of a target language, ensuring grammatical accuracy in the output sentences.
Since different communities have different cultural traditions, training AI models on material in Indigenous
languages, particularly ancestral stories and folk tales, can lead to unintended consequences. As Coleman explained,
certain stories are traditionally told only during the wintertime in his community. “How do you maintain that tradition
if it’s available online?” he says. In other words, AI models do not understand cultural nuance (细微差别). If they
are not trained appropriately, they can mishandle sensitive cultural information.
Indigenous researchers are undertaking AI language preservation initiatives to promote greater accessibility
and diversity at the forefront of technological innovation. As researchers Uma Pradhan and Joyeeta Dey have
explained, AI language preservation helps address historical injustice for communities previously discouraged or
even prohibited from speaking their native tongues. These initiatives not only support language revitalization (复兴) by
increasing the number of speakers but also emphasize the cultural significance of these languages within technological
spaces long dominated by English, Mandarin Chinese and a handful of other global languages.
1． What is the function of the first paragraph?
A．To criticize the limits of robot technology.
B．To detail the Anishinaabe language history.
C．To analyze language revitalization challenges.
D．To introduce the topic with a specific example.
2． What is a major challenge in using AI for Indigenous language translation?
A．Lack of public data for training.
B．High cost of developing AI models.
C．Resistance from Indigenous communities.
D．Complexity of English and Spanish grammar.
3． Why does Jared Coleman mention the tradition of telling stories only in winter?
A．To argue that stories should not be told online.
B．To show that AI can help record seasonal activities.
C．To explain how AI models learn from seasonal data.
D．To illustrate the risk of AI ignoring cultural nuances.
4． What is the main purpose of AI language preservation initiatives?

For sports fans, attending a live match with their favorite team playing is exciting. For the visually challenged,
however, this usually means giving up the commentary (解说) from TV broadcasts and relying on their companions
to know what’s going on in the game. Hoping to change the situation, OneCourt has created a clever tactile (触觉的)
device, aiming to make the excitement of live sports accessible to all.
The device, a tactile display, is designed to sit comfortably on the user’s lap. Its surface is a faithful copy of
the game field or court, with the plays being turned into vibrations (震动) that fans can follow with their fingertips.
As the ball moves across the court or field, the corresponding vibration on the device also shifts position.
Currently, the device supports three popular sports: basketball, football, and baseball, the latter of which was
put to the test during the MLB’s 2024 All-Star Weekend, proving its functionality and reliability. OneCourt explains
that they collect ball and player positional data tracked at the league level. This data is then translated into a special
tactile language, which is presented as trackable vibrations on the device’s surface.
Recently, the Portland Trail Blazers became the first NBA team to partner with OneCourt. The device is
available at home games at no additional cost. The team welcomed blind Paralympian Anthony S. Ferraro to show
the device at work. While using it, the athlete was excited to discover how quickly the players were moving on the
court. “This was a life-changing experience, and I can’t wait until devices like this are applied across the board in all
sports and events,” Ferraro said. The device is of great help to the visually challenged following a game at home, but
it really shines at an in-stadium event, where fans can take in the live game in front of them and feel the energy of
like-minded sports fans.
1． Why does the author mention “commentary from TV broadcasts” in paragraph 1?
A．To show the awkward situation the visually challenged face.
B．To introduce the popularity that TV sports broadcasts enjoy.
C．To highlight the role live sports commentary plays in a match.

Born between the mid-1990s and early 2010s, Gen Z is often labelled as “digital natives”. Therefore, it may
come as a surprise that Gen Z is turning away from screens and heading outdoors. From forest bathing to camping
trips, more young adults are embracing nature as part of their lives.
Digital burnout is driving change. Gen Z spends more time online than any other generation, with daily screen
time averaging 6-9 hours. According to a recent survey by Pew Research Centre, over 60% of Gen Z respondents
reported feeling overwhelmed by the pressures of staying digitally connected. Therefore, nature offers an escape. For
Gen Z, being outdoors isn't just leisure, it’s a form of essential self-care.
Ironically, the very platforms driving digital burnout are now fuelling nature engagement. Social media is not
just part of the problem but it’s also part of the solution. Popular hashtags such as #Hiking, #Ice Bathing,
#RunningClubs, and #VanLife have received billions of views online. Health and lifestyle influencers share experiences
of these activities, reframing nature as desirable and reachable. Although access to nature is still limited by safety
concerns, cost, and urban density, Gen Z is adapting as best as they can. From sharing equipment to joining outdoor
clubs, they’re finding creative ways to reclaim public spaces.
Reconnecting with nature is also driven by environmental values. From eco-tourism to zero-waste hiking, Gen
Z approaches outdoor time with purpose. Gen Z is reshaping global movements, using social media to spread climate
advocacy and redefine sustainable living. This generation is embracing outdoor experiences that are low-cost, low-
tech, and deeply fulfilling. Amongst all these activities, run clubs and social fitness events have exploded in
popularity.
With a growing number of Gen Z passionate about spending time outdoors, it’s evident that many are turning
to nature to restore balance, foster connection, and contribute to a healthier world.

The US government is currently weighing a crucial decision: whether to grant African lions protection under
the Endangered Species Act, which would prohibit the import of lion trophies into the U.S., marking a significant
step for an endangered species. This proposal raises a pressing question: why is it still legal to hunt lions for sport
when they are vanishing from the wild?
Scientific evidence underscores the urgency. A recent study estimates as few as 32,000 lions remain in the
wild, with some experts fearing the true number is lower. While the primary drivers of their decline are habitat loss
and retaliatory killings by humans, trophy hunting adds unsustainable pressure. Each year, approximately 600 more
lions are killed for sport, approximately 60 percent of which are shipped to the U.S. as trophies.
The damage caused by trophy hunting runs deeper than the initial kill. The preferred target is the adult male
lion whose removal destabilizes the entire pride. When new males take over, they frequently kill all the cubs generated
by the previous leader, wiping out a generation within the pride. This practice is also evolutionarily damaging, as it
removes the strongest, healthiest males vital for protecting their prides and passing on strong genes to future
generations.
Some argue that trophy hunting brings money to local communities. Yet, studies show that only about 3% of
the income actually reaches them. Most of the money goes to governments or foreign companies. The money that
does come into Africa from hunting pales in comparison to the billions generated from tourists who come just to
watch wildlife. If lions and other animals continue to disappear from Africa, this vital source of income will end,
adversely impacting people all over Africa.
Despite decades of discussion about reforming hunting practices, lion numbers continue to fall. As the only
big cat not currently protected by the Act, the African lion stands at a crossroads. Granting them protection and
banning trophy imports would send a powerful global message: the time to act is now, before this iconic species is
lost forever.
1． What will be the direct result if African lions are protected by the Act?
A．Lion hunting would become illegal worldwide.
B．The import of lion trophies into the U.S. would be banned.
C．The number of lions in the wild would immediately increase.
D．Local communities in Africa would receive more financial support.
2． What impact does killing a male lion have according to the passage?

The tiny worm Caenorhabditis elegans has a brain just about the width of a human hair, yet it can coordinate
and calculate complex movements as it hunts for food. Daniela Rus, a computer scientist at MIT, was so deeply
impressed by the elegance and efficiency of this worm’s brain that she co-founded a company, Liquid AI, to build a
new type of artificial intelligence.
Many researchers including Rus think making traditional AI more brainlike could create flexible and perhaps
smarter technology. “To improve AI truly, we need to absorb insights from neuroscience (神经科学),” says Kanaka
Rajan, a computational neuroscientist at Harvard University.
Mike Davies, who directs the Neuromorphic Computing Lab, notes such technology won’t fully replace
ordinary computers or traditional AI models — instead, many systems will coexist in the future. Imitating brains is
not a new idea. In the 1950s, Frank Rosenblatt created the perceptron, a highly simplified model of brain nerve cell
communication with a single layer of connected artificial neurons. This basic design later helped inspire deep learning.
Yet consuming vast amounts of data and energy, most today’s AI models are unable to adapt easily to new situations or
learn from single experiences like a brain, and are criticized as “brute force and inefficient.” Currently, AI development
has two paths — “scale-up” vs. “efficiency-focused” — with an uncertain future while brain-inspired neuromorphic
computing progress hasn’t joined mainstream AI.
Inspired by the worm, Rus worked with Ramin Hasani’s team to create liquid neural networks. Unlike traditional
deep learning with fixed post-training settings, these networks are more flexible and can learn like living things. By
copying worm neurons with mathematical formulas and solving computing problems, they can work in real time.
Tests showed with just 34 artificial neurons a small liquid network worked better than a traditional AI with 250,000
settings in drone tasks. Liquid AI has worked with DARPA to test aircraft models and launched the 7-billion-setting
LFM-7B, which performs better than similar traditional language models.
Though needing much computing power and not necessarily more energy-saving, liquid neural networks are
an important step toward realistic, brain-like AI. As Rus says, “I’m excited about Liquid AI because I believe it could
change the future of AI and computing.”
1． What mainly inspired Daniela Rus to establish Liquid AI?
A．The limitations of traditional AI models.
B．The efficiency of the tiny worm’s brain.
C．The worm’s cooperative food-hunting skills.
D．The pursuit of more flexible and smarter technology.
2． What does Mike Davies suggest about future AI development?
A．Brain-like technology has little practical value.
B．Neuromorphic computing will dominate the AI field.
C．Different AI systems may work together in the future.
D．Traditional AI models will be completely abandoned.
3． What makes liquid neural networks special?
A．They have fixed settings after training.
B．They depend on few mathematical formulas.
C．They work worse than traditional AI in tasks.
D．They can learn flexibly like living creatures.
4． What is the main idea of the last paragraph?
A．Liquid AI has both limits and value.
B．Brain-like AI has been fully achieved.
C．Traditional AI is more reliable than liquid AI.
D．Liquid AI will definitely control the AI market.

Lots of papers have been published on the advantages of bilingualism (双语制). Beyond the conversational
doors it can open, bilingualism is supposed to improve the ability to ignore distractions, plan complex tasks and
update beliefs as new information arrives. Most strikingly, numerous studies have even shown that bilinguals develop
a later dementia (痴呆), perhaps of around four years, on average. A study from 2019 showed that bilingualism
does mitigate age-related decline.
The biggest benefits seem to come to those who master their second languages fully. Switching languages
frequently in the course of a day may be particularly important. A bit of university French does not, unfortunately,
convey the same advantages as deep knowledge and long experience. Studies of interpreters and translators have
provided some of the strongest evidence for a bilingual advantage. For example, they are faster at jumping back and
forth between simple addition and subtraction problems than monolinguals, suggesting generally better cognitive (认知)
control.
Studies have found striking evidence that in poorer parts of the world multilingual people show the strongest
advantages from speaking several languages. Where schooling is limited, researchers assumed that bilingualism
exercises children’s brains in a way that their schooling may not.
Age plays a role, too. Studies suggest that the effects of languages on the brain are stronger for young children
and the old than they are for young adults. One meta-analysis on the topic revealed that 25 studies out of 45 found a
bilingual advantage in children younger than six, while only 17 found them in children aged 6-12.
But all these studies take for granted the mental superpower that you get from language study: being able to
talk to people you could not have spoken to, or understood, otherwise. Even if you cannot be fluent from infancy (幼儿),
that should be more than enough reason to give it a go.
1． What does the underlined word“ mitigate” most likely mean in paragraph 1?
A．Speed.

B．A professor who reads academic papers in another language.
C．A social media influencer who occasionally uses foreign phrases.

3． What can be inferred about the “bilingual advantage” from the text?
A．It’s only determined by the number of involved languages.
B．It’s strongest for those with higher education.
C．It’s limited for children living in poor areas.

Hydrogen (氢) fuel cells make electricity by combining hydrogen and oxygen, and the only product is water.
They start fast, work efficiently, and produce zero emissions. However, most fuel cells still depend on platinum(a
chemical element) as the catalyst (催化剂). Platinum is rare and very expensive, so large-scale use is difficult.
A team of Chinese scientists has offered a strong solution. Their study, published in Nature, shows that an
iron-based catalyst can do the job while using far less platinum. The team, led by Prof. Dan Wang and Prof. Zhang
Suojiang, designed a structure they call “inner activation, outer protection”. The active iron atoms sit inside tiny
hollow (中空的) shells, while a hard carbon layer outside protects them.
Think of each particle (颗粒) like a set of nested shells. The iron atoms are fixed on the inner curved surface.
The outer carbon shell keeps the particle stable. This setup makes oxygen pieces escape more easily, so the reaction
runs faster. It also blocks harsh chemicals that would damage the catalyst over time.
Tests support the design: the iron atoms are in the right places and stay steady during use. Computer models
explain why it works — the outer layer gently pushes away oxygen pieces, so they don’t stick too tightly to the iron
inside.
The performance is impressive for a catalyst without platinum. The fuel cell loses less energy, produces less
of a harmful oxygen-based chemical, and stays active for a long time. It reached about 0.75 W/cm 2 and kept about
86% of its activity after over 300 hours.
This Chinese breakthrough matters. Firstly, it lowers costs and eases pressure on rare-metal supply chains by
replacing much platinum with iron. Besides, the simple “inner activation, outer protection” rule can guide new
catalysts for fuel cells, and metal-air batteries. Moreover, longer-lasting parts lower costs for backup power, helping
clean technology grow faster. In short, smart atomic design from China offers a practical path toward cleaner air,
stronger energy security, and progress toward climate goals.

Staring at the bookcases in my study, packed with so many great books that had remained unread, I heard a
loud voice in my head — “Shame on you! How can you leave these masterpieces unread?”
The first book I picked up was Montaigne’s Essays. To my surprise I discovered in the margins (页边空白)
what clearly was my own faded hand-writing. So I was actually reading it again, but what I was rereading seemed
entirely new. I also found sentences underlined. Only this time I wondered: Why did I underline this sentence? It’s
the next one that is important!
Clearly, my way of reading the text had shifted, and I myself had changed over the years. This raised the larger
question of rereading. It comes in many forms. There’s voluntary rereading, the result of a willful decision to revisit
a book one has admired, or a book that has left one with some unanswered questions. This kind of planned revisit
could also be for confirming certain details in the text, or for checking on the moves of a given character. A devoted
teacher might also wish to refresh his closeness to a work, and thus avoid teaching through the same old written notes
with soporific (让人瞌睡的) effects.
Contrarily, there’s involuntary rereading. The original reading was either forgotten or so totally absorbed that
the new chance encounter with the text produced surprise and astonishment. My reaction to the renewed reading no
longer corresponded to the original experience, and I was no longer sure that I recognized myself as the same
reader.
Then there are what one might call subconscious (潜意识的) rereadings, those that occur without the specific
act of reading, much as the memory of a tune can keep coming back to the mind without its actually being heard
again. This form of remembered contact with a book can accompany us during a lifetime and continue to strengthen
and shape us. Much in the same manner, we may over the years recite to ourselves poems learnt by heart long ago,
which have become part of our self-recognition.
All of these ways of reading are valuable. Renewed contact with a novel or a poem can activate the search
for a better knowledge of the self. The new reading a form of revision, uncovers the change in us. The newness is not
in the text. It is we who have evolved. In the process of rereading, our outlook has also been significantly changed.
Rereading makes it possible for us to see the world around us, ourselves included, in a new light.
1． According to the author, what could be a purpose of voluntary rereading?
A．To improve the quality of teaching.
B．To learn from admirable characters.
C．To collect details for writing novels.
D．To help making important decisions.
2． According to Paragraph 4, what can involuntary rereading bring about?
A．Unexpected reading experience.
B．Total concentration on new books.
C．Changed preferences for books.
D．Enhanced reading skills.
3． What can be learnt about subconscious rereading?
A．It prevents memory from fading.
B．It helps make who we are.
C．It involves actual reading.
D．It works best with poetry and music.
4． What could be the best title for the passage?
A．Accessing Masterpieces through Rereading.
B．Rereading: Voluntary or Involuntary?
C．Rereading: Pursuit of Truth.
D．Transformative Power of Rereading.

A recent study by NYU Abu Dhabi reveals that space rays, high-energy particles (粒子) from space, may
generate the energy necessary to support underground life on planets and moons in our solar system. This discovery
challenges the long-held belief that life can only live near sunlight or volcanic heat.
The research, published in the International Journal of Astrobiology and led by Dimitra Atri, shows that space
rays are not always harmful. In fact, they can help microscopic life (微生物) survive. When space rays hit underground
water or ice, they break water molecules (分子) apart, releasing electrons (电子). On Earth, some bacteria can use
these electrons for energy, just as plants use sunlight. This process, called radiolysis (辐射分解), can sustain life in
dark and cold places without sunlight.
Using computers, the researchers explored how much energy this process could generate on Mars and the icy
moons of Jupiter and Saturn. These moons are thought to have hidden water beneath their thick ice layers. The study
found that Saturn’s moon Enceladus has the greatest potential to support life through radiolysis, followed by Mars
and Jupiter’s moon Europa.
“This discovery changes the way we think about where life might exist,” said Atri. “Instead of looking only
for warm planets with sunlight, we can now consider places that are cold and dark, as long as they have some water
beneath the surface and are exposed to space rays. Life might be able to survive in more places than we ever
imagined.”
The study also introduces the concept of the Radiolytic Habitable Zone, which is different from the traditional
“Goldilocks Zone”. Since space rays are widespread in space, there may be many more life-supporting places in the
universe.
The findings provide new guidance for future space missions. Instead of only looking for signs of life on the
surface, scientists might also explore underground environments on Mars and the icy moons, using tools that can
detect chemical energy created by space radiation. This research opens up exciting new possibilities in the search for
life beyond Earth and suggests that even the coldest and darkest corners of the solar system could harbor life.
1． What common sense does the NYU study mainly challenge?
A．Space rays have caused great harm.
B．Life merely depends on solar energy.
C．Alien life really exists on other planets.
D．Volcanic heat is needed on icy moons.
2． How does radiolysis help sustain life?
A．By generating light needed by life.
B．By reflecting sunlight to water below icy layers.
C．By separating water molecules to free electrons.
D．By making dark and frozen areas warmer.
3． What does the underlined word “harbor” in the last paragraph mean?
A．Control,

As we enter a period of profound economic uncertainty, presaged (预示) by recent high-profile layoffs and a
culture of “quiet quitting”, thinking about the future of work might well seem a daunting (令人生畏的) prospect.
Indeed, an ever-increasing digital skills gap threatens to stop businesses adopting the game-changing
technologies that will help to power growth in the months and years ahead. For instance, with each exciting new
technology comes a growing concern about whether we have a digitally savvy (精明的) workforce ready to take
advantage of it. After all, keeping the workforce up to speed with the latest advances is a key element of the digital
transformation process, which will prove essential if we hope to improve business productivity and efficiency
alongside our efforts to achieve sustained growth.
Likewise, at the World Economic Forum’s annual meeting in Davos, the cybersecurity skills gap was named
as one particular area of concern. There’s good reason for this focus: if businesses can’t protect themselves against
external threats, they risk going backwards. And that’s before they even start thinking about achieving growth. This
is why we need to address the digital skills gap urgently.
Well, we should start by changing the narrative to help us recruit and retain from a more diverse pool of talent,
giving businesses a far better chance of finding the up-to-date digital skills they need. And, when it comes to engaging
and empowering the current workforce, learning and development opportunities will be key, helping employees to
improve their skills for the benefit of both themselves and their employers.
To make this all happen, leaders and employers must demonstrate a commitment to teaching their workforces
digital skills by setting clear expectations and providing all the resources required. One approach, for example, would
be to focus on the potential in the existing talent pool by identifying those already skilled in digital capabilities and
supporting them to up skill their colleagues. Creating a culture of learning, with an emphasis on personal growth, can
be an impressive motivator in the workplace.
Of course, it’s all well and good saying that digital skills are vital, but a workforce with purely hard skills will
not future-proof a business. There’s a need for soft skills that support the broader goal, so as not to neglect the other
competencies required in a digital transformation: communication, critical thinking, creative design skills, and
leadership. To exploit the technology to its full potential, such qualities are equally important.
Fundamentally, getting the interaction right between humans and technology will be paramount if businesses
are to succeed. As a result, human skills must not be underestimated. Every business will need a range of people
with a variely of skills — not only those well-versed in math, engineering, and science, but also those with creative
minds and leadership qualities.

France banned smartphones in primary and secondary schools in 2018 to improve focus, reduce social media
exposure, and control cyberbullying. Following this, the Netherlands and Hungary introduced similar bans in 2024,
while the UK debates comparable legislation. The critical debate centers on whether such bans meaningfully enhance
students’ mental health.
The urgency is undeniable. A 2021 U.S. Surgeon General report documented a 40% surge in persistent
hopelessness among American high schoolers between 2009 and 2019. The number who seriously considered killing
themselves went up by 36%. What makes these findings all the worse is that 48% of mental-health problems (like
depression and anxiety) that emerge during adolescence will plague people for the rest of their lives.
It is tempting to connect these trends with the increased availability of smartphones, but establishing a causal
connection is difficult. The brain undergoes profound changes during adolescence, meaning that any research on the
effects of smartphone use needs to consider the developmental age of the children being studied as well as their
precise smartphone habits.
Some studies reveal that unfettered (不受限制的) access to social media on smartphones at critical moments
when the brain is changing may cause problems. Amy Orben at the University of Cambridge surveyed 17,409 people
aged 10-21, analyzing the relationship between social media use and life satisfaction. The findings show that girls
who increased their social media use over the course of a year were significantly less satisfied if the increase took
place when they were between 11 and 13. Boys showed the same trend when increases took place when they were
14 or 15 years old.
How much of this will change by banning phones in schools is unclear. Victoria Goodyear at Britain’s University
of Birmingham compared the mental well-being of students in schools that implemented restrictive smartphone
policies with those with relaxed policies. She also monitored overall screentime. Her results show that, while those
who spent more time on a smartphone overall did have a decline in mental well-being, there was no difference
between the two groups. She and her colleagues argue that setting up policies at schools alone is simply not
enough.

Researchers have developed a novel inhalable ( 吸入式的) drug delivery system for lung cancer using
mucoadhesive protein nanoparticles (MPNs) inspired by marine mussels’ (贻贝) characteristics.
Lung cancer remains one of the leading causes of cancer-related deaths worldwide. Non-small cell lung cancer,
accounting for 85% of cases, is difficult to treat due to delayed detection and the deleterious effects of traditional
treatments, where anticancer drugs circulate throughout the body and damage healthy tissues.
Inhaled therapies offer a promising alternative, delivering drugs directly to the lungs. However, the efficiency of
this approach has been affected by the lung’s mucosal ( 粘膜的) barriers and immune cells. Building on this,
collaborative research developed MPNs for lung cancer treatment. This approach takes advantage of the gluey feature
of marine mussel proteins.
This characteristic allows the nanoparticles to be firmly attached to the lung’s mucosal surfaces,ensuring that
the drugs are released precisely in tumor (肿瘤) areas while minimizing exposure in healthy tissues. As a result, side
effects are reduced. Additionally, the natural breakdown properties and low immune response of mussel proteins
make the treatment safer and help the drugs stay longer in the lungs, boosting their effectiveness.
In lung cancer animal models, the drug-loaded nanoparticles effectively reduced tumor spread and invasion
after being delivered through a breathing machine and remaining attached to the lung’s mucosal surface for an
extended time. This advancement holds the potential to enhance patient access to lung cancer treatment, as the
simplified inhalable drug administration could be self-managed at home. Furthermore, this approach may significantly
improve patients’ quality of life by reducing the need for hospital visits.
The study has also drawn attention from researchers in the wider scientific community. Dr. Hana Lee from
Seoul National University described the MPNs as a “guided missile” in cancer treatment — precise, efficient, and
minimally invasive. This level of precision offered a rare combination of specificity and simplicity not often found
in conventional treatments.

What do you do as spring sets in? Taking off your warm winter coat, and putting it away? For humans, taking
off winter coats is a one-minute task. As it turns out, not all animals are so capable.
Snowshoe rabbits live in the mountain ranges of North America, and have a pure white coat during the winter
time to match the snowy surroundings and to help avoid being caught. And they take off winter coats for a darker
brown fur color to match the dirt and leaves after the snow melts in the spring. Sounds like a great way to escape
from their natural enemies, right? However, concern begins when scientists begin looking at how the warming climate
will impact the rabbits.
There are more and more white rabbits in the middle of a brown habitat, where the snow has already melted
away. This is a problem for them, as they are more easily seen by their natural enemies, giving them a “mismatch”
problem. Snowshoe rabbits time the coat change in spring from white to brown based on the change in day length,
not the temperature or the presence of snow in their habitat. Nowadays, the snow is melting a week on average before
the change in day length signals the change in coat color, leaving the rabbits exposed to their natural enemies.
Some predictions put the rabbits in up to 8 weeks of a white coat in a brown, snowless habitat by the end of
this century. This timeline could spell doom for their populations, as their natural enemies will have nearly 2 months
of easily spotting them.
Fortunately, scientists have found areas with snowshoe rabbits in color from white to brown in the same place,
meaning the timing of the coat change can be influenced by the environment. Snowshoe rabbits reproduce quickly,
and if the color change timing is passed down then it is possible for rabbits to change coats accordingly. By protecting
areas with variable ones, we can give snowshoe rabbits the opportunity to adapt to the changing climate.
1． Why does the author mention humans’ taking off winter coats?
A．To stress climate change is influential.
B．To imply animals should be taken care of.

Cast your mind back to the last time you ate at a restaurant. Who were you with? How did the food taste? Did
you get some food on your pants? This ability to mentally time travel to a past event is called episodic memory (情
节记忆). But how much of what you just recalled is wrong? In a new study, Nicholas Diamond explored how faithful
our episodic memory is.
We all know that memory is not a perfect record of the past: we forget and we sometimes remember incorrectly.
Earlier studies have shown that various factors, such as emotional intensity or misleading questions, can lead to false
memories. Thus, there has been a widespread belief that human memory is highly subject to error. Yet these studies
are usually conducted under relatively artificial conditions in the laboratory. Very little is known about the accuracy
of memories for real-world experiences, ones that make up our lives outside the laboratory.
To address the issue, Nicholas Diamond assessed participants’ memories for a controlled audio-guided art tour
in his research. Younger and older adult participants freely recalled the event, describing their experiences in as much
detail as they could, after delays ranging from two days to two years. Diamond then decomposed these memories
into basic details (e.g. actions, sensory elements, irrelevant information, etc.), and measured their accuracy against
the ground truth.
In contrast to scientists’ previous predictions of an over 50% recall error rate, research results revealed episodic
memory accuracy was very high overall (93% — 95%), although errors were indeed detectable (76% of participants
made at least one). Moreover, this level of accuracy did not decline in older participants or in older memories, even
though memory quantity and vividness did. In a word, although our episodic memories fade with age and time, the
memories we do recall remain highly accurate.
So, you can go ahead and have faith in your memories that include, unfortunately, the ones about getting food
on your pants.

A．Unaffected.
B．Complex.
C．Unreliable.
