专题02 上下文猜词技巧及实例解析
高考时文阅读中的生词多与社会热点、科技发展、文化交流等主题相关，猜词无需依赖复杂词汇储备，核
心是抓住“上下文逻辑关联”和“已知信息线索”。以下5 种方法均附明确操作步骤，直接对应做题场景。
方法讲解
1. 因果逻辑猜词法
适用场景：原文中出现表示因果关系的连词/短语，如because、so、therefore、thus、as a result、due
to、owing to 等，生词多为原因或结果的核心词。
操作步骤：① 圈出因果关系标志词；② 确定“已知信息”（原因/结果中明确的部分）；③ 根据因
果逻辑推导生词含义——“原因→结果”或“结果→原因”反向推导。
关键提醒：因果逻辑前后语义一致，无矛盾，推导时可直接套用“因为A，所以B”或“因为B，所以
A”的句式验证。
2. 同义/近义替换猜词法
适用场景：原文中出现表示同义关系的标志，如that is、in other words、namely、or、also、too，或通
过“破折号、括号”补充说明，生词与后文的已知词构成同义关系。
操作步骤：① 找到同义关系标志（连词/标点）；② 定位标志后紧跟的“解释性已知词/短语”；③ 直接
将已知词的含义代入生词位置，验证语义是否通顺。
关键提醒：时文阅读中，作者常通过“同义替换”避免重复，补充说明的内容多为简单易懂的常用词，是
猜词的“直接线索”。
3. 反义/对比逻辑猜词法
适用场景：原文中出现表示对比关系的连词/短语，如but、however、yet、while、on the contrary、in
contrast、unlike 等，生词与后文的已知词构成反义关系。
操作步骤：① 圈出对比关系标志词；② 提取标志词前后的“对比主体”及已知主体的属性；③ 推导生
词含义为已知属性的“相反面”，代入原文验证逻辑是否成立。
关键提醒：对比逻辑的核心是“差异”，推导时需注意区分“绝对反义”（如开/关）和“相对反义”（如
快/慢），结合时文主题判断具体含义。
4. 举例说明猜词法
适用场景：原文中出现表示举例的标志词，如for example、for instance、such as、like 等，生词为“例子所
归属的类别/属性”，例子本身为已知信息。
操作步骤：① 识别举例标志词；② 梳理标志词后的“具体例子”，提炼例子的共同属性；③ 确定生词
含义为“具备该属性的类别”。
关键提醒：时文阅读中的例子多贴近生活或热点（如科技产品、社会现象），提炼属性时优先关
注“功能、特征、用途”。
5. 语境逻辑猜词法（无明显标志时适用）
适用场景：原文无因果、同义、对比等明显标志词，需依赖“段落主旨”或“上下文情节发展”猜
词。
操作步骤：① 通读生词所在的整段内容，明确段落主旨（如“介绍新能源汽车的优势”“说明垃圾分
类的意义”）；② 分析生词在句中的成分（主语/宾语/定语），判断其与主旨的关联；③ 结合情节
发展逻辑，代入符合主旨的常见含义，验证句子通顺度。
关键提醒：时文主旨多明确（热点话题的介绍、观点的阐述），猜词时不可脱离主旨“凭空联想”，
优先选择与主题相关的含义。

案例
5 ：语境逻辑猜词法（社会主题）
原文片段：In recent years, more and more cities have introduced bike-sharing services. People can rent a
bike at a low price and return it at any designated station. This convenient service has won widespread
popularity among citizens. （生词：designated）
解析步骤：① 通读段落，明确主旨：介绍共享单车服务的便利性② 分析生词成分：“designated”作
定语修饰 ”（站点），与共享单车“租赁、归还”的流程相关；③ 结合语境推
导：共享单车需在“指定的”站点归还，才能保证服务有序，推测“designated”意为“指定的”；④
验证：“在任何指定站点归还”，符合共享单车的运营逻辑，与“便利服务”的主旨一致。
答案：
.
总结：高考时文猜词的核心是“找线索、扣主旨”，优先使用有明确标志的方法（因果、同义、对
比、举例），无标志时紧扣段落主题推导，代入验证通顺即可，无需纠结生词的精确词典含义，只要
能匹配做题需求即可。

Passage 1
“I’ve always loved practising Nirmal painting, but I wondered: Will anyone value it enough to keep it
alive?” says Mohammad Abdul Hakeem, an artisan ( 工匠) from Telangana. With traditional art forms slowly
losing their place in the modern world, the artisan felt apprehensive about the future. But his life changed when he
met Sushmita Kaneri, who used to be a software engineer.
In 2021, Sushmita visited Telangana and met artisans practising Nirmal art, a wood-based craft known for its
storytelling through painting. “I saw how these artisans had been practising the craft for generations, but fewer and
fewer people were noticing it,” Sushmita explains. “The artisans felt that their hard work was neither recognised
nor fairly valued. That’s when I knew I had to do something,” she adds.
In April 2023, Sushmita founded “Gullakaari”, a platform designed to connect artisans with customers, co-
create art, and raise awareness about endangered art forms while helping artisans support their lives. By offering a
marketplace for traditional art forms like Warli, Patachitra, and Gond, the platform allows artisans to reach a
broader audience and benefit from a steady stream of orders.
When asked about how she has used her software engineering skills in her work, Sushmita says, “We use
tech only where it adds value without changing the soul of the craft. For example, we trained the Tholu Bommalata
artisans to create lamp covers with 3D- printed logos on them. When it is lit, the lamp beautifully lights up not only
the fine artwork but also a 3D- printed logo, mixing traditions with modern technology.”
In just two years, Sushmita has helped more than 100 artisans make a living by using their traditional art
styles to make functional products. Hakeem shares, “Working with Gullakaari has truly opened new doors for us. In
the past, we had to rely on middlemen who often paid us less. Thanks to Gullakaari, now our work can reach
companies and art lovers from across the country.”
1．Which is closest in meaning to “apprehensive” in paragraph 1?
A．Optimistic.
B．Curious.
C．Worried.
D．Annoyed
2．How can Gullakaari benefit artisans?
A．By broadening their customer base.
B．By connecting with more middlemen.
C．By highlighting its storytelling feature.
D．By teaching them software skills.
3．Why is the 3D- printed lamp cover mentioned?
A．To promote modern technology.
B．To introduce a new art form.
C．To show how old skills are replaced.
D．To illustrate how tradition meets technology.
4．What is the last paragraph mainly about?
A．Unfair trade in the past.
B．The impact of Gullakaari.
C．Innovative products in the market.
D．The hope of artisans.
Passage 2
Millions of tourists travel to parks each year to enjoy the bright colors of fall — but ecologists say the
familiar reds, oranges and yellows of fall foliage (叶子) are coming later in the season. “In New England, generally
the fall foliage tends to peak in mid-October,” said Richard Primack, a professor of plant ecology. “But because of
a warming climate, the peak of fall foliage is tending to move from kind of early to middle October to kind of
middle to late October.”
Predicting precisely when the leaves will turn from green to red, orange and yellow in fall depends in part on
the geographic area, the species and the amount of rainfall, and climate change can largely determine the timing.
And leaves of trees with harmful insects will drop sooner, according to Christy Rollinson, a forest ecologist.
“Bright colors are associated with a healthy tree, because some colors take energy for the tree to produce.”
Peak color used to last for about two weeks, but for certain species, that period might be becoming more
condensed as higher temperatures continue late into the fall while days shorten at the same rate. So future
generations might just have to be ready to travel at a moment’s notice to catch a peak period in parts of the country.
Such changes could affect the tourism industry surrounding leaf peeping (看), according to Sarah Blount, a
researcher at the National Environmental Education Foundation. She underscored how important it is to try to
improve peak timing predictions. “There’s so much money attached to it.” she said. “People want to buy a plane
ticket to go somewhere and don’t want to find that it turns out that it’s too late and all the leaves are gone or it’s too
early, so there is a lot of focus on trying to improve the information that we have about that.”
5．What do Richard’s words show?
A．The lateness of peak fall foliage.
B．The rareness of a trend.
C．The impacts of climate change.
D．The mass appeal of fall colors.
6．What does paragraph 2 mainly talk about?
A．Visible signs of the coming of fall.
B．Prediction of fall foliage’s color change.
C．Factors in the timing of colorful fall foliage.
D．Determinants of the brightness of colors.
7．Which is closest in meaning to the underlined word “condensed” in paragraph 3?
A．Irregular.
B．Important.
C．Lengthy.
D．Brief.
8．What does Sarah Blount imply?
A．The country relies heavily on tourism.
B．Predicting peak foliage precisely is vital.
C．It takes effort to protect the environment.
D．Scheduling leaf-peeping trips early is better.
Passage 3
It seems obvious that plants cannot count 1-10 on their roots or leaves as we usually do with our fingers, but
scientists say certain plants can “count” and even do simple maths. They possess mysterious abilities to keep an eye
on the insects nearby and their own food stores.
Venus flytraps, for example, are known to shut their leaves rapidly when they sense something moving on
them. But they only do this if anything moves twice within about 15-20 seconds. The movements are sensed by fine
‘trigger’ hairs on the leaves and translated into electrical pulses ( 脉 冲), flowing through the plant. When an
electrical pulse is triggered twice, the leaves will close immediately.
But as a group of international scientists showed in 2016, insect-eating plants of this kind are able to tally
higher than two. They wait until they’ve sensed at least three electrical pulses before they start producing the
chemicals needed to digest their catch, probably to avoid wasting their energy on lucky escapees.
Even before this discovery, though, scientists were suggesting that thale cress, a cousin to cabbage that’s
widely used in plant studies, could perform a process similar to doing division. During the day, thale cresses use
sunlight to build up their food stores, which is known as photosynthesis. But to survive the night, they must first
determine how much energy they will need. They do this by assessing the energy stored in their leaves and
factoring in the length of the night. Based on this calculation, they then manage their food intake at a sustainable
rate.
Experts argue we shouldn’t label these curious counting abilities as “intelligent” or as evidence that plants
have some early and underdeveloped form of brain. They’re just doing what they need to survive. But it reminds us
that even the simplest forms of life can display astonishing complexity and precision.
9．The example of Venus flytraps in Paragraph 2 is given to show that _________
A．plants can count 1-10 on their roots and leaves
B．some plants can carry out simple calculations
C．plants are able to generate electrical pulses
D．certain plants react much faster than insects
10．The underlined word “tally” in Paragraph 3 is closest in meaning to_________·

11．We can learn from the passage that_________
A．venus flytraps set timed traps based on how many bugs they sense
B．plants do simple maths to kill time other than merely to survive
C．thale cress manages its energy use at night through calculation
D．plants have now evolved a structure similar to a human brain
12．What might be the best title for the article?
A．Plants’ amazing sense of time and space
B．Plants’ smart tricks of capturing bugs
C．Plants’ brilliant use of sunlight and energy
D．Plants’ surprising talent for mathematics
Passage 4
Not successful enough for senior leadership roles but too experienced (and expensive) for the front-line
positions artificial intelligence (AI) hasn’t replaced, many mid-career professionals of America’s workforce
suddenly find themselves in no-man’s-land.
Many major companies like Amazon and Target have announced white-collar staff reductions recently. Gone
are the days when employers would reserve talented employees or worry about being understaffed for the good
times. When a job description calls for 10 to 15 years of experience, 25-year seasoned professionals aren’t
necessarily seen as better-than-expected prospects. They’re often viewed as applicants who will ask for too much
money and leave as soon as they find better opportunities.
However, we ought to be aware of the real circumstances of overqualified job applicants in daily life. Some
people want less responsibility than in previous roles and are willing to take pay cuts accordingly. Others have been
out of work for months and have no desire to job hop once they finally get hired.
Anthony Nigbur, 41, was a top healthcare program manager. He’s been job hunting since May, with a
recruiter (招聘专员) submitting him for roles. “He’s told me the feedback about his experience: ‘This guy has all
this experience, but we don’t need it or know how to use him,’ ” says Nigbur. He wishes to explain to prospective
employers why he’d take a job that seems beneath him on paper. That’s because he’s willing to take the lead
parenting role as his wife, a nurse, has upped her hours and travel.
The way companies have cut middle management is so striking that a new study projects a shortage of 2. 9
million managers in 2032. By then, middle management will be a hot job again, the study predicts. That doesn’t do
people like Nigbur much good today. Experienced sales manager Anne Marie Sterling found that playing down her
experience was a key to landing her current job at a solar energy company. The 55-year-old Florida resident tells
me she had to “play dumb”. “That happens a lot in job interviews. There’s no doubt about it,” she says.
13．What do we know about overqualified candidates in the US job market?
A．They’ll be easily replaced by AI.
B．They’ve held senior leadership roles.
C．They’re struggling to get hired now.
D．They’re highly valued by companies.
14．What’s the author’s attitude to employers’ views on overqualified job seekers?
A．Unclear.
B．Doubtful.
C．Tolerant.
D．Disapproving.
15．What can be inferred about Nigbur?
A．He hasn’t landed an interview.
B．He needs the professional experience.
C．He’s already had a well-paid job.
D．He doesn’t want to be a husband.
16．What do the underlined words “play dumb” in paragraph 5 probably mean?
A．Keep the peace.
B．Tell the truth.
C．Act less capable.
D．Stay more independent.
Passage 5
By scanning a QR code at a service station, Li Xinpeng had his parcels delivered by an unmanned vehicle,
thanks to the launch of the first rural drone delivery route in Wuhan, Hubei Province.
The drone is capable of flying at a speed of 70 kilometers per hour and cruising (巡航) at an altitude of 120
meters. Operated by skilled professionals, the payload hexacopter drone boasts an impressive one-hour flight
endurance (耐力) and can carry as many as 300 to 500 parcels at a time.
“Sometimes a delivery journey would have taken me over 40 minutes on my motorcycle,” remarked Liu
Jianying, a postman from the Xinzhou branch of China Post Group (CPG), adding that drone deliveries are not
hindered by traffic jams or other road conditions. “The drones will significantly reduce transport time and enhance
the efficiency of parcel distribution,” he said.
In collaboration with CPG, the local government in Xinzhou pioneered Wuhan's first rural drone delivery
route, which is currently undergoing test flights across three pilot villages. It is predicted to officially launch flight
operations in early December, with plans to expand to 13 villages within the region upon the successful completion
of the trial phase.
Xinzhou district is located in the remote Dabie Mountains, featuring vast mountains and forests. Most of the
villages are quite far apart in this area, leading to a dispersed (分散的) population. As online shopping experiences
significant growth and the demand for delivery continues to rise, this drone delivery route is expected to become an
important supplement.
“During the initial stages, the purchase, maintenance and operation costs of drones might be relatively high.
But in the long term, as drones become widely used, the unit costs will decrease, effectively addressing issues
related to labor shortages and high logistics costs,” Zhang Dawei, a professor from the institute of urban and rural
governance at Central China Normal University, was quoted by Hubei Daily as saying.
17．What do we know about the drone?
A．It can cruise at an altitude of 300m.
B．It can only take off in rural regions.
C．It can fly at a speed of 120 km/h.
D．It can carry hundreds of parcels at once.
18．What does the underlined word “hindered” mean in paragraph 3?
A．Reduced.
B．Lost.
C．Blocked.
D．Misled.
19．Why does the writer mention the location of Xinzhou District?
A．To emphasize its national status.
B．To advocate regional protection.
C．To introduce the natural scenery.
D．To explain reasons for using drones.
20．What is the future of drone delivery according to Professor Zhang Dawei?
A．Promising.
B．Tough.
C．Alarming.
D．Uncertain.
