语篇类型:说明文 主题:海狸鼠皮毛时装 词数:324 难度:★★★
建议时间:7分钟
高考真题
When you were trying to figure out what to buy for the environmentalist on your holiday list,
fur probably didn't cross your mind. But some ecologists and fashion(时装) enthusiasts are trying
to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have
showcased nutria fur made into clothes in different styles. "It sounds crazy to talk about guilt-free
fur — unless you understand that the nutria are destroying vast wetlands every year,"says Cree
McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail.Some of
the fur ends up in the fashion shows like the one in Brooklyn last month.Nutria were brought there from Argentina by fur farmers and let go into the wild."The
ecosystem down there can't handle this non-native species( 物 种 ).It's destroying the
environment.It's them
or us,"says Michael Massimi,an expert in this field.
The fur trade kept nutria in check for decades, but when the market for nutria collapsed in the
late 1980s, the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it's not easy
to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more
than 300,000 nutria tails a year, so part of Mouton's job these days is trying to promote fur.
Then there's Righteous Fur and its unusual fashions. Model Paige Morgan says, "To give
people a guilt-free option that they can wear without someone throwing paint on them — I think
that's going to be a massive thing, at least here in New York." Designer Jennifer Anderson admits
it took her a while to come around to the opinion that using nutria fur for her creations is morally
acceptable. She's trying to come up with a label to attach to nutria fashions to show it is eco-
friendly.
28.What is the purpose of the fashion shows in New Orleans and Brooklyn?
A. To promote guilt-free fur. B. To expand the fashion market.
C. To introduce a new brand D. To celebrate a winter holiday.
29.Why are scientists concerned about nutria?
A. Nutria damage the ecosystem seriously.
B. Nutria are an endangered species.
C. Nutria hurt local cat-sized animals.
D. Nutria are illegally hunted.
30.What does the underlined word "collapsed" in paragraph 5 probably mean?
A. Boomed. B. Became mature.
C. Remained stable. D. Crashed.
31.What can we infer about wearing fur in New York according to Morgan?
A. It's formal. B. It's risky.
C. It's harmful. D. It's traditional.
Passage 2
语篇类型:记叙文 主题:志愿者工作的意义 词数:302 难度:★★建议时间:7分钟
高考真题
"You can use me as a last resort(选择), and if nobody else volunteers, then I will do it."
This was an actual reply from a parent after I put out a request for volunteers for my kids'
lacrosse(长曲棍球) club.
I guess that there's probably some demanding work schedule, or social anxiety around
stepping up to help for an unknown sport. She may just need a little persuading. So I try again and
tug at the heartstrings. I mention the single parent with four kids running the show and I talk about
the dad coaching a team that his kids aren't even on... At this point the unwilling parent speaks
up,"Alright. Yes, I'll do it."
I'm secretly relieved because I know there's real power in sharing volunteer responsibilities
among many. The unwilling parent organizes the meal schedule, sends out emails, and collects
money for end-of-season gifts. Somewhere along the way, the same parent ends up becoming an
invaluable member of the team.
The coach is able to focus on the kids while the other parents are relieved to be off the hook for
another season. Handing out sliced oranges to bloodthirsty kids can be as exciting as watching
your own kid score a goal.
Still, most of us volunteers breathe a sigh of relief when the season comes to a close. That
relief is coupled with a deep understanding of why the same people keep coming back for more:
Connecting to the community (社区) as you freely give your time, money, skills, or services
provides a real joy. Volunteering just feels so good.
In that sense, I'm pretty sure volunteering is more of a selfish act than I'd freely like to admit.
However, if others benefit in the process, and I get some reward too, does it really matter where
my motivation lies?
24.What can we infer about the parent from her reply in paragraph 1?
A. She knows little about the club.
B. She isn't good at sports.
C. She just doesn't want to volunteer.
D. She's unable to meet her schedule.
25. What does the underlined phrase "tug at the heartstrings" in paragraph 2 mean?
A. Encourage teamwork. B. Appeal to feelings.C. Promote good deeds. D. Provide advice.
26.What can we learn about the parent from paragraph 3?
A. She gets interested in lacrosse. B. She is proud of her kids.
C. She'll work for another season. D. She becomes a good helper.
27.Why does the author like doing volunteer work?
A. It gives her a sense of duty. B. It makes her very happy.
C. It enables her to work hard. D. It brings her material rewards.
五、考法解题能力提升
考法1 猜测生僻词或短语的含义
命题透视 词义猜测题的重点就是对于生僻词汇及短语含义的理解,这也是高考中词义
猜测题最常见的类型。
方法点拨 若画线词完全是生词,考生能采用的方法主要有三种:一是依据构词法知识;二
是靠文章显性或者隐性的逻辑关系、语法关系;三是利用上下文语境。当然,在很多情况下,
这三种方法可以共同使用,以确保答案正确。
I had been educated in the rhythms of the mountain, rhythms in which change was never
fundamental, only cyclical. The same sun appeared each morning, swept over the valley and
dropped behind the peak. The snows that fell in the winter always melted in the spring. Our lives
were a cycle — the cycle of the day, the cycle of the seasons — circles of lasting change that,
when complete, meant nothing had changed at all. I believed my family was a part of this
immortal(永生的) pattern, and that we were, in some sense, eternal(永恒的). But eternity
belonged only to the mountain.
...
25.What does the underlined word "cyclical" in the passage mean?
A. Normal. B. Irregular.
C. Circular. D. Traditional.
Lighting matters, too. When Berlin restaurant customers ate in darkness, they couldn't tell
how much they'd had: those given extra-large shares ate more than everyone else, but were none
the wiser — they didn't feel fuller, and they were just as ready for dessert.
...
58.The underlined phrase "none the wiser" in paragraph 3 most probably implies that thecustomers were .
A. not aware of eating more than usual
B. not willing to share food with others
C. not conscious of the food quality
D. not fond of the food provided
考法2 猜测熟词或短语的生僻含义
命题透视 高考近几年开始侧重于考查熟词生义,如2020年全国Ⅰ第26题考查了课标词
汇currency在具体语境中的生僻含义,这就要求考生掌握并灵活运用课标词汇。
方法点拨 在猜测熟词的生僻含义时,我们可以依据上下文语境、文章的逻辑关系等来
判断正确答案。
We've all known people who run out of steam before they reach life's halfway mark. I'm not
talking about those who fail to get to the top. We can't all get there. I'm talking about people
who have stopped learning on growing because they have adopted the fixed attitudes and opinions
that all too often come with passing years.
…
52.What does the underlined part in Paragraph 3 probably mean?
A. End one's struggle for liberty.
B. Waste one's energy taking risks.
C. Miss the opportunity to succeed.
D. Lose the interest to continue learning.
考法3 猜测代词的指代意义
命题透视 纵观近五年高考阅读理解中的代词指代题可以看出,高考中常考的是人称代
词(I, it, them)以及指示代词that的指代对象, 2020年新高考Ⅰ(山东)第9题考查了指示代词
that的指代, 2019年全国Ⅱ第21题考查了人称代词I的指代。
方法点拨 1.文章中的代词it, that, them等通常指代上文提到的人或事物,因此其指代含
义也通常在其前的内容中寻找。
2.有时代词与指代的对象相隔较远,要认真查找;有时需要对前面提到的内容进行总结,才能得
出代词所指代的事物。
3.一般来讲,代词指代题不会单纯从语法角度考查指代对象,都需要借助上下文语境以及逻辑
关系来进行猜测。
The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash thesame length of green twice in a row, especially at rush hour. At 9:30 am, the full red/yellow/green
signal cycle might be 140 seconds. By 9:33 am, a burst of additional traffic might push it to 145
seconds. Less traffic at 9:37 am could push it down to 135. Just like the traffic itself, the timing of
the signals changes.
That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is
gaining popularity around the US: intersection (十字路口) signals that can adjust in real time to
traffic conditions. These lights, known as adaptive signals, have led to significant declines in both
the trouble and cost of travels between work and home.
...
25.What does the underlined word "that" in paragraph 2 refer to?
A. Increased length of green lights.
B. The shortened traffic signal cycle.
C. Flexible timing of traffic signals.
D. Smooth traffic flow on the road.
考法4 猜测句子含义
命题透视 猜测句子含义题是近几年新出现的一种设问方式。一般来讲,画线句中生词
不占主导地位,但无法单独通过字面意思理解句子的隐含意义。如2019浙江6月第24题猜
测"Money with no strings attached"在文中的含义,2018全国Ⅲ第32题猜测"more is more"在文
中的含义。
方法点拨 针对猜测句子含义的试题,考生必须回归原文,将画线句的前后句,甚至前后段
进行归纳总结,再将自己理解的意思与选项的意思逐个比较,选出最为接近的选项。解答此类
试题的线索主要有两个:一是上下文语境,二是句子的字面含义。
Archeology(考古学) isn't the dusty science which was a generation ago. New technologies
that once seemed out of sci-fi are now locating buried traces of buildings and revealing the ruins
of cities... Now Sarah Parcak and her team are about to take on a new challenge as they focus
GlobalXplorer citizen-science project on India.
...
In the future, she hopes other countries will contact her to launch their own satellite surveys.
The possibilities are huge. Parcak estimates that there are at least 12 million potential
archaeological sites yet to be discovered. That means the sky is the limit for her project ...
11.What does the underlined sentence "The possibilities are huge" mean?A. Parcak's project will become successful.
B. Few countries will start satellite surveys.
C. There will be amazing discoveries in India.
D. More archaeological sites will be identified.

记叙文 克服对"水"的恐惧 356 ★★ 6分钟
At eleven, I decided to learn to swim. There was a pool at the YMCA offering exactly the
opportunity. My mother continually warned against it, and kept fresh in my mind the details of
each drowning in the river. But the YMCA pool was safe.
I had a childhood fear of water. This started when I was three years old and my father took
me to the beach. The huge waves knocked me down and swept over me.
The pool was quiet. I was afraid of going in all alone, so I sat on one side of the pool to wait
for others. Then came a big boy. He yelled, "Hi, how’d you like to be ducked?"With that he picked
me up and threw me into the deep end. I landed in a sitting position, and swallowed water. But I
was not frightened out of my wits — when my feet hit the bottom, I would make a big jump to
come out of the surface. It seemed a long way down. I gathered all my strength when I landed and
made what I thought was a great spring upwards. Then I opened my eyes and saw nothing but
water. I tried to yell but no sound came out. I went down, down, endlessly.
When I came to consciousness, I found myself lying on the bed in the hospital.
I never went back to the pool. I avoided water whenever I could. This misadventure stayed
with me as the years rolled by. It deprived me of the joy of boating and swimming. Finally, I
decided to get an instructor. Piece by piece, he built a swimmer. Several months later, the
instructor was finished, but I was not. Sometimes the terror would return.
This went on until July. I swam across the Lake Wentworth. Only once did the terror return.
When I was in the middle of the lake, I put my face under and saw nothing but bottomless water. I
laughed and said, "Well, Mr.Terror, what do you think you can do to me?"
I had conquered my fear of water.
1.The author’s original fear of water was caused by .A. his poor skill in swimming

2.Why was the author not scared to death when he was thrown into the water?
A. He knew how to swim in the pool.
B. He felt that the YMCA pool was safe.
C. He was waiting for others to save him.
D. He came up with an idea of going upwards.
3.By expressing "but I was not" in Paragraph 5, the author probably means .

议论文 2020东京奥运会推迟 355 ★★ 7分钟
The decision on Tuesday by Japan and the International Olympic Committee (IOC) to
postpone the Tokyo 2020 Olympic Games until next summer because of the COVID-19 pandemic
must have been a hard one to make.
Although the Games have been canceled — three times in all, in 1916, 1940 and 1944 — due
to the two world wars, in the modern Olympics’ history of more than 120 years, never before have
any Games been postponed to a different year.
Nonetheless, the decision is the right one. If it is not brought under control, the harm done to
human society by the pandemic could be more serious and far-reaching than even the two world
wars. Given the number of countries affected and social and economic shock waves that have beencaused by the rapid spread of the virus, postponing the Games is the only right and sensible choice
to make.
After all, nothing is more important than people’s lives. Postponing the Games not only
safeguards the health of athletes, audiences and everyone involved in the Games, but also reduces
potential transmission of the virus from one place to another. Even looking at it from only a
sporting level, the pandemic has already caused huge disruptions to athletes’ training and the
qualification process.
It is undoubtedly a big blow for Japan, which has prepared meticulously for the largest sports
event in the world, including renovating and upgrading its infrastructure and sports venues, such
as rebuilding Tokyo’s Olympic Stadium at a cost of $1.45 billion. Japan will suffer a huge loss, at
least in the short term.
The international community owes a big "thank you" to Japan for all it has done for the
Games despite the postponement. That’s why the Games will still be called the Tokyo 2020
Olympic and Paralympic Games despite taking place in 2021. The Olympic flame will also remain
stored and displayed in Japan.
More importantly, all members in the Olympic family, guided by the Olympic spirit of
respect and understanding, are morally bound to stand behind Japan to go through this most
difficult moment in the Games’ history.
1.What does the word "it" in Paragraph 3 refer to?
A. The decision. B. The Games.
C. The pandemic. D. The war.
2.What does the underlined word"meticulously" in Paragraph 5 probably mean?
A. Wisely. B. Recently. C. Easily. D. Precisely.
3.We know from the passage .
A. the Games should be put off in times of wars and disasters
B. the Games will still be called the Tokyo 2020 Olympic and Paralympic Games for Japan’s
sacrifice
C. postponing the Games will have a bad influence on the athletes
D. the Olympic family will have to make up for the loss of Japan
4.What can we learn from the last paragraph?
A. The Olympic family will support Japan.B. Japan will keep the Olympic flame burning.
C. Postponing the Games will bring the world hope.
D. Tokyo will become the symbol of the Games.

说明文 何为"老" 262 ★★★ 7分钟
An ageless question: When is someone "old"?
What does "old" really mean these days? This isn’t a meaningless question — not only does
the definition of "old" have an outsized impact on how we feel about ourselves (not to mention
how others view us), it also matters to policymakers determining how to plan for aging
populations.
The United Nations historically has defined older persons as people 60 years old or over
(sometimes 65). It doesn’t matter whether you live in the United States, China or Senegal, even
though life expectancy is quite different in each of those countries. Everyone becomes old at 60.
Researchers Sergei Scherbov and Warren Sanderson, who study aging, are suggesting
overturning the one-size-fits-all definition of "old". Instead, they talk about "prospective age",
which looks to the future. Everyone with the same prospective age has the same expected
remaining years of life.
Scherbov explained that "young" and "old" are relative concepts, and their common reference
point is life expectancy. And that "old" would vary between nations makes sense, especially
between more and less developed countries, with differences in education, death rates, access to
health care and life expectancy.
But who is "old" also varies — widely — between individuals. The point, says Scherbov, is
that personal age is dependent on our "characteristics" — understanding abilities, disability, health
history and even education levels. Those with more education tend not to smoke, exercise more
frequently, have better diets and have regular checkups — and, therefore, live longer, meaning the
beginning of their old age comes later, says Scherbov.
1.What is the first paragraph mainly about?
A. How we feel about ourselves.
B. The definition of "old".
C. The importance of the definition of "old".D. The plan for aging populations.
2.What does the underlined phrase "prospective age" in paragraph 3 refer to according to the text?
A. The expected remaining years of one’s life.
B. The beginning of one’s old age.
C. The differences of our "characteristics".
D. The age when one becomes old.
3.What similarity does Scherbov think "young" and "old" have?
A. Understanding abilities. B. Nations.
C. Education. D. The reference point.
4.Which of the following helps one to live longer according to Scherbov?
A. As much exercise as possible.
B. Losing weight.
C. Studying history.
D. Improving the education level.

说明文 能自学合作技能的机器人 317 ★★ 7分钟
Never play games with a bot (robot) — it will find a way to cheat if it can. A
team from OpenAI, an artificial intelligence lab in San Francisco, has developed
artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek.
The bots also learned how to use basic tools to help win.
Bowen Baker at OpenAI and his colleagues wanted to see if the team-based
dynamics of the OpenAI Five could be used to produce skills that could one day be
useful to humans.
The researchers set their bots loose in a simulated(模拟的) environment filled with
fixed walls, movable boxes and ladders, and left them to play team games of hide-and-
seek. The bots each had their own view of the world and couldn’t communicate with
each other directly.
At first, the hiders simply ran away. But they soon worked out that the quickest way
to stop the seekers was to find objects in the environment to hide themselves from view.
The seekers learned that they could move boxes around and use them to climb overwalls. The bots then discovered that being a team-player — passing objects to each other
or cooperating on a hideout — was the quickest way to win.
But the real surprise came when the bots started making use of problems or faults.
Seekers found that if they pushed a ladder towards a wall, they could launch themselves
into the air and spot hiders from above. Hiders found that they could get rid of the
ladders by pushing them aside.
It shows that AI bots are able to find solutions that humans miss, says Baker.
"Maybe they’ll even be able to solve problems that humans don’t yet know how to."
However, it is a large leap(跳跃) from virtual hide-and-seek to real problem-solving. "The
main limitation is that it is in simulation," says Chelsea Finn at Stanford University.
1.Why did Bowen and his colleagues conduct the research?
A. To teach bots to play games.
B. To train bots to use basic tools.
C. To find if bots may cheat like humans.
D. To see the potential of bots’ cooperation.
2.What’s the third paragraph mainly about?
A. The tools of the research.
B. The design of the research.
C. The competitors of the game.
D. The environment of the game.
3.What does the underlined word "It" in the last paragraph refer to?
A. Passing objects. B. Moving boxes around.
C. Making use of faults. D. Hiding themselves from view.
4.What does Chelsea think of the finding of the research?
A. It can bridge a gap in the AI research.
B. It will not be influenced by the real world.
C. It will definitely help the real problem-solving.
D. It may not be realized out of the virtual world.

说明文 头像与性格间的关系 327 ★★★ 8分钟When we meet someone for the first time, we usually get a vague sense of what
kind of person they are by the way they shake hands, talk or walk. In the age of social
networking, however, first impressions are sometimes made even before we actually meet
someone in person — that is, by looking at their profile photo.
According to a recent study, these social images say a lot about our personality. In
the study, a group of researchers from the University of Pennsylvania in the US used
software to analyze the profile pictures of 66,000 users of one US social platform. At the
same time, about 434 participants were asked to complete a survey about their personality
type.
According to the results, open people are more likely to pose in an unusual way and
use objects such as glasses or a guitar in their profile photo because they enjoy new and
exciting experiences. Meanwhile, neurotic people often hold back their negative emotions.
They try to avoid showing their face; instead, they use an image of something like a pet,
a car or a building. That’s because neurotic people are strongly influenced by the "strong
social norm against a very sad or angry appearance in profile pictures".
Apart from the objects in profile pictures, the colors used in them also give us some
information about the photo’s owner. For example, extraverts were found to have the most
colorful profile images, as they want to emphasize their personality and show themselves
off.
Daniel Preoiuc-Pietro from the University of Pennsylvania wrote in the research paper,
"Social media photos usually represent an extension of one’s self, but they also allow a
user to shape his or her own personality and idealized view." So, when choosing a profile
photo, maybe we should ask ourselves first what kind of image we’d like to convey.
After all, first impressions always last.
1.Why do neurotic people often avoid showing their face in their profile photo?
A. Because they are fond of pets, cars and buildings.
B. Because they want to enjoy new experiences.
C. Because they don’t want to expose their negative images.
D. Because they are not confident about themselves.
2.What does the underlined word in Para.4 refer to?A. Open people. B. Neurotic people.
C. Negative people. D. Popular people.
3.What is the writer’s attitude towards the choice of a profile photo?
A. Casual. B. Cautious.
C. Worried. D. Unclear.
4.What does this text mainly talk about?
A. The relationship between one’s profile photo and his personality.
B. Some advice on how to choose a profile photo.
C. The difference between open people and neurotic people.
D. The importance of the first impression.

新闻报道 中国努力研制新冠疫苗 253 ★★★ 8分钟
Inside the white, bacteria-free walls of a new building on the southern outskirts of
Beijing, two employees wearing masks and rubber gloves are busy injecting a clear,
colorless liquid into rows of small bottles.
The 215,000 square feet production plant was built in recent months specifically for
producing a COVID-19 vaccine (疫苗) developed by Chinese pharmaceutical company
Sinovac Biotech.
CoronaVac, the vaccine candidate from Sinovac, is part of China’s push to be at the
forefront of rolling out immunizations (免疫接种) against the deadly novel coronavirus.
The Nasdaq-listed biotech company began developing its vaccine in late January.
By June, China had largely contained the epidemic, dealing with only a small number
of outbreaks. Those newly reported COVID-19 cases in China didn't meet the necessary
conditions for a Phase 3 trial, so Sinovac reached an agreement with Brazil — which
then ranked second in the world for cases of infection, with more than 3.6 million
reported cases.
In cooperating with the Butantan Institute in São Paulo, a Phase 3 study was
launched in late July involving 9,000 volunteers, all health professionals who had worked
with COVID-19 patients but hadn’t been infected with the virus.The tests are ongoing, but Dimas Covas, president of the Butantan Institute, said
Wednesday primary data showed CoronaVac developed immunity in 97% of the people
vaccinated after two doses — a level he said was "fundamental to break the chain of
transmission of the coronavirus".
1.From which of the following is the text probably taken?
A. A biology textbook. B. A news report.
C. A book review. D. A travel brochure.
2.What does the underlined phrase "rolling out" in Paragraph 3 mean?
A. Launching. B. Distributing.
C. Guarding. D. Burning.
3.What is the necessary condition for a Phase 3 trial?
A. China’s successful containment of the epidemic.
B. A sufficient number of infected patients.
C. All health professionals and volunteers.
D. The Nasdaq-listed biotech company.
4.Which can be a suitable title for the text?
A. The forefront: China’s push to develop a coronavirus vaccine.
B. Lockdown: China’s successful move to contain the outbreaks.
C. Infection: Brazil’s ranking second surprises the world.
D. Immunity: Brazil’s efforts to break the chain of transmission.
