北京市朝阳区三年（2020-2022）高考英语模拟试题分题型分层汇编-02阅读理解
一、阅读理解
（2022·北京朝阳·统考二模）One of the great things about pictures is that they make no demands on you. You can look as long as you like and walk away at any time. There's a freedom in the arrangement that's different from going to the movies, concerts or the theater. Occasionally, people always say they feel intimidated by art. On the one hand, I get it. Some in the art world, wanting to establish their authority, fall back on abstractions to create a zone of exclusion. It can be insufferable. But on the other hand, what field doesn't see a version of this phenomenon Have you tried understanding cellular biology Contract law In my experience, there is less of this complex talk around art than around most other fields.
Art is a wide field. It's deep. It's diverse. You can come at the subject from countless angles. People seem to have been making art since the beginning, so the subject is an inseparable part of the whole history of humanity. So yes, things can get complicated. But, in the end, we're talking about pictures and sculptures. How hard is it to look at a painting How difficult is it to walk around a sculpture Children get it immediately. They know there's no right or wrong when it comes to looking at art. There are just things to notice, to test against our imperfect sense of the truth, and to fold into our various conceptions of beauty. Things we notice may cause feelings. They may lead to ideas. They might equally provide a release from ideas-a release into wonder, and into new kinds of awareness connected to your body, your senses, and your general state of existential confusion. What I notice will be different from what you notice. That's how it goes with art.
More than the political or economic conditions of any given era, it is art that later generations most want to remember. We remember Picasso and Matisse with more love than General Francisco Franco or Marshall Petain. And we remember the Beatles and Francis Bacon over the chief ministers of Britain in the 1960s. That's because the arts-and I define the term as broadly as possible-reveal the best of us. It's because they combine the most intelligent and the most feeling of us. They testify, most fundamentally, to the fact that we're alive, that people lived before us, that as a species we're capable of making the most extraordinary things, and that human consciousness and the world beyond it are nothing short of astonishing.
Again and again, art expresses that astonishment — that mixture of wonder and disappointment, knowing and unknowing, pleasure and pain, joy and fear.

（2022·北京朝阳·统考二模）Harvest
Tabby walked on her way to school. She felt a sense of anticipation because this year she would be one of the graduates being honored at the town festival.
These days, she was waiting to hear back about an admission application she sent to her top- choice college. It had the program that she was most excited about. Today she stayed late at school to get feedback on another college essay from Ms. Mueller, her high school teacher. Ms. Mueller told Tabby that her essay was very moving and that she knew Tabby would miss her hometown, but her degree would be worth it. Tabby responded gratefully.
On the way home, the sight of the festival decorations made her feel guilty. She knew that most of her classmates could happily enjoy the festival knowing that they would be going on to do exactly what was expected of them-carrying on the town’s traditions by staying close to family and farm. Spending many years at a large university in a city somewhere far from home wasn’t supposed to be part of their plan.
When Tabby got home, her family was preparing packages with homemade cookies to sell at the festival.
“Let’s make an assembly line (流水线),”said Tabby.
“Always trying to improve the process, aren’t you ” her brother laughed. Tabby knew what he was referring to. Last summer, Tabby discovered a technique for improving grain storage without costly equipment, which was adopted by local farmers.
After completing packing, Tabby went to her room. On her bed, she saw a large envelope from the college she was waiting to hear from. She had been accepted into the famous college-the one with the world-renowned agricultural science program!
The first person Tabby shared the news with was her grandfather. He gave her a big hug. “I guess my scientist girl still has farming in the blood, ” he said. “Yes! And I will come back and do some research right here in a few years,” she said. “Well, this old farm could certainly use some improvements! I’m proud of you, Tabby!” he said.
5．Why did Tabby stay late at school
A．To get advice on her college essay.
B．To say goodbye to her teacher.
C．To express her thanks to her high school.
D．To wait for her admission letter.
6．Tabby felt guilty because she ________ .
A．failed to live up to her teacher’s expectations
B．skipped out on helping set up the decorations
C．planned on leaving to pursue a higher education
D．could not assist her classmates to get into college
7．According to the passage, Tabby will probably ________.
A．contribute to the farming in her hometown
B．choose a famous college close to her home
C．adopt her grandfather’s advice to be a scientist
D．apply her knowledge to college agriculture projects

（2022·北京朝阳·统考二模）Millions of migratory(迁徙的)birds occupy seasonally favorable breeding(繁殖)grounds in the Arctic, but scientists know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. In a new study, a multinational team of researchers under the leadership of Dr. ZHAN Xiangjiang from the Institute of Zoology of the Chinese Academy of Sciences integrated two state-of-the-art techniques-satellite tracking and whole genome sequencing(基因排序)-and established a continental-scale migration system of peregrine falcons in Eurasian Arctic.
The researchers tracked 56 peregrine falcons from six Eurasian Arctic breeding populations and sequenced 35 genomes from four of these populations to study the migration of this species. They found that the birds used five migration routes across Eurasia, probably established between the last Ice Age 22, 000 years ago and the middle-Holocene 6, 000 years ago. “Peregrine falcons initiated their autumn migration mainly in September, and arrived at their wintering areas mainly in October, " said Professor Mike Bruford, an ecologist at Cardiff University. “Peregrine falcons that depart from different breeding grounds use different routes, and winter at widely distributed sites across four distinct regions. Individual birds that were tracked for more than one year exhibited strong path repeatability during migration, complete loyalty to wintering locations and limited breeding dispersal(扩散). ”
The researchers quantified the migration strategies and found that migration distance is the most significant differentiation. They used whole genome sequencing and found a gene-ADCY8, which is known to be involved in long-term memory in other animals in previous research- associated with differences in migratory distance. They found ADCY8 had a variant at high frequency in long-distance migrant populations of peregrine falcons, indicating this variant is being favorably selected because it may increase powers of long-term memory thought to be essential for long-distance migration.
“Previous studies have identified several candidate genomic regions that may regulate migration-but our work is the strongest demonstration of a specific gene associated with migratory behavior yet identified, ”Professor Bruford said. The researchers further looked at models of likely future migration behavior to predict the impact of global warming. If the climate warms at the same rate as it has in recent decades, they predict peregrine populations in western Eurasia have the highest probability of population decline and may stop migrating altogether.
“Our work is the first to begin to understand the way ecological factors may interact in migratory birds, ” said Dr. ZHAN Xiangjiang. “We hope it will serve as a cornerstone to help conserve migratory species in the world. ”
11．What can we learn from the first two paragraphs
A．Five birds’ historical migration routes were rebuilt.
B．Peregrine falcons stick to the areas where they winter.
C．Two novel research methods of migration were invented.
D．Peregrine falcons leave for Arctic regions in September.
12．What can we infer about ADCY8

B．It serves as a fundamental part of long-distance migration.
C．It could be strengthened by the power of long-term memory.
D．It turned out to be more favored by birds than the other animals.
13．What is special about the new study
A．It has discovered a new genomic region of birds.
B．It has predicted the rate at which the climate warms.
C．It analyses the reasons for the decrease of peregrine falcons.
D．It encourages attention to environmental effects on migratory birds.
14．Which would be the best title for this passage
A．Researchers Help Conserve Migratory Species
B．Biologists Find Evidence of Migration Gene in Birds
C．How Long-term Memory Helps Long-distance Migration
D．How Ecological Factors Affect Birds’ Migratory Distances
（2022·北京朝阳·校联考模拟预测）Six-year-old Alice is building a magical kingdom brick by brick, imagining fairy-tale castles and fire-breathing dragons, bad witches and brave heroes. This fantasy is helping her take her first steps towards her capacity for creativity. Minutes later, Alice has abandoned the kingdom in favour of playing schools with her younger brother. When she bosses him around as his “teacher”, she’s practising how to regulate her emotions through pretense. Later on, when they tire of this and settle down with a board game, she’s learning about the need to follow rules and take turns with a partner. Although she isn’t aware of it, this will play an important role in her adult life.
“Play in all its rich variety is one of the highest achievements of the human species,” says Dr. David Whitebread from the University of Cambridge. It underpins how we develop as intellectual, problem-solving adults and is crucial to our success as a highly adaptable species. Recognising the importance of play is not new: over two millennia ago, the Greek philosopher Plato extolled its virtues as a means of developing skills for adult life, and ideas about play-based learning have been developing since the 19th century.
But we live in changing times, and Whitebread is mindful of a worldwide decline in play, pointing out that over half the people in the world now live in cities. Whitebread, Baker, Gibson and a team of researchers hope to provide evidence on the role played by play in how a child develops.
“A strong possibility is that play supports the early development of children’s self-control. This is our ability to develop awareness of our own thinking processes. It influences how effectively we go about undertaking challenging activities,” explains Baker. In a study carried out by Baker with toddlers and young preschoolers, she found that children with greater self-control solved problems more quickly when exploring an unfamiliar set-up requiring scientific reasoning.
Gibson said, “Playful behaviour is also an important indicator of healthy social and emotional development. In my previous research, I investigated how observing children at play can give us important clues about their well-being and can even be useful in the diagnosis of neurodevelopmental disorders like autism.”
Whitebread’s recent research has involved developing a play-based approach to supporting children’s writing. “Many primary school children find writing difficult, but we showed in a previous study that a playful stimulus was far more effective than an instructional one. Children wrote longer and better-structured stories when they first played with dolls representing characters in the story.
Somehow the importance of play has been lost in recent decades. It’s regarded as something trivial, or even as something negative that contrasts with “work”. Let’s not lose sight of its benefits, and the fundamental contributions it makes to human achievements in the arts, sciences and technology. Let’s make sure children have a rich diet of play experiences.
15．What is the purpose of the first paragraph
A．To illustrate the benefits of too much spare time.
B．To describe a kid’s peaceful and happy childhood.
C．To present the importance of a rich variety of play.
D．To introduce the distinctive functions of different toys.
16．What does the underlined word “underpins” in Paragraph 2 probably mean
A．Weakens. B．Reinforces. C．Investigates. D．Influences.
17．What has Whitebread’s recent research found out
A．Children with greater self-control solve problems faster.
B．Children at play often show hints about their well-being.
C．Students write better when they integrate work with play.
D．Play promotes healthy social and emotional development.
18．How does the author feel about current people’s awareness of play
A．Curious. B．Satisfied. C．Cheerful. D．Concerned.

（2022·北京朝阳·校联考模拟预测）The car has reshaped our cities. It seems to offer autonomy for everyone. There is something almost delightful in the separation from reality of advertisements showing mass-produced cars marketed as symbols of individuality and of freedom when most of their lives will be spent making short journeys on choked roads.
Despite top speeds and cornering ability advertised, the most useful gadgets on a modern car are those which work when you’re going very slowly: parking sensors, sound systems, and navigation apps which will show a way around upcoming traffic jams. These apps know where almost all the users are, and how fast they are moving almost all the time, they can spot traffic congestion (堵塞) very quickly and suggest ways round it.
The problem comes when everyone is using a navigation app which tells them to avoid everyone else using the same gadget. Traffic jams often appear where no one has enough information to avoid them. When a lucky few have access to the knowledge, they will benefit greatly. But when everyone has perfect information, traffic jams simply spread onto the side roads that seem to offer a way round them.
This new congestion teaches us two things. The first is that the promises of technology will never be realised as fully as we hope. They will be limited by their unforeseen and unintended consequences. Sitting in a more comfortable car in a different traffic jam is pleasant but hardly the liberation that once seemed to be promised. The second is that self-organisation will not get us where we want to go. The efforts of millions of drivers to get ahead do not miraculously produce a situation in which everyone does better than before, but one in which almost everyone does rather worse. Central control and collective organization can produce smoother and fairer outcomes, though even that much is never guaranteed.
Similar limits can be foreseen for the much greater advances promised by self-driving cars. One autonomously operated car by the taxi company Uber struck and killed a woman pushing her bicycle across a wide road in Arizona. Experts have said that it suggests a “catastrophic failure” of technology.
Increasingly, even the top tech-company has to acknowledge the costs of intoxicating (令人陶醉的) hurry that characterizes its culture. What traffic teaches us is that reckless and uncontrolled change is as likely to harm us as it is to benefit us, and that thoughtful regulation is necessary for a better future.
22．What can we infer about the car advertisements
A．They present a false picture of the cars.
B．They emphasize the mass production of cars.
C．They portray drivers enjoying speed on the road.
D．They pursue individuality and freedom in design.
23．What can we know about the various gadgets on cars
A．They are constantly upgraded.
B．All of them are used effectively.
C．Only some can be used frequently.
D．They can help to relieve traffic jams.
24．What does the author say about the use of the navigation app
A．It benefits those who are learning to drive.
B．It is likely to create traffic jams in other places.
C．It helps a great deal in easing traffic congestion.
D．It sharply reduces the occurrence of traffic accidents.
25．What do we learn about technology from the passage
A．It seldom delivers all the benefits as promised.
B．Its consequences are usually difficult to assess.
C．Its benefits are guaranteed by collective wisdom.
D．It depends on the required knowledge for application.
（2022·北京朝阳·校联考模拟预测）Golden Girl
My mother looks just like many grandmothers. She is short, plump, and white-haired. She’s rosy-cheeked and cheerful, and when she laughs her eyes almost seem to disappear behind those chubby cheeks. She comes from an old, traditional Catholic family. She was a career civil servant. In short, she didn’t do crazy stuff.
That all changed a few years ago. She began to surprise my older brother and me with what she described as “independence.” At the time, we merely saw them as examples of irresponsibility and possibly age-related questionable judgment.
In the year she turned 75, she informed us she’d booked a seven-night trip to Turkey. A vulnerable little old lady wandering on her own, not knowing the language and customs— There was no way we could allow that! She paid no attention to us and off she went. She hired a taxi driver who showed her around, and bought some rugs from a vendor, who promised to ship the rugs home and apparently struck up quite a friendship with her.
We couldn’t believe how naive she was and explained that she had been tricked. However, her rugs arrived some weeks later. As did a lovely note from Mustafa. To our even greater surprise, the following year Mustafa himself arrived, and promptly called our mother to inform her of that fact.
At 77, she did a similar thing while on a Caribbean cruise with her younger sister. She wandered off on her own, and had a motorcycle rickshaw driver “show her around the island” for several hours.
Still, her 80th birthday was when she really outdid herself. During the birthday lunch with her family, Mom informed us that she decided she had to get her first tattoo. It seemed so absurd we didn’t believe it. Six days later, she had a tasteful butterfly on the outside of her left ankle.
My brother and I wondered: Had she become addlebrained (糊涂) But Mom proved that she was thinking straighter than most of us. Her seek of independence seems to be thoughtfully based on a realization that life is to be lived, and when there’s relatively little of it left, it needs to be lived now. I don’t think Mom knows what her next big “thing” is. She’s a little old lady who sits in her apartment, but she won’t sit still much longer.
26．What was the reason the author and his elder brother believed for Mom’s changes
A．Her age-related decline.
B．Her changeable personality.
C．Her Catholic family background.
D．Her retirement from her job as a civil servant.
27．Why did Mustafa show up immediately he arrived Canada
A．To sell rugs again to Mom.
B．To pay a visit to his friend.
C．To give Mom a rug as a gift.
D．To collect money from last trip.
28．What can we conclude from this passage
A．An old in a home is like a treasure of a family.
B．It is never too late to live our lives to the fullest.
C．It’s not acceptable to get a tattoo when people turn eighty.
D．One should always seek adventures with strangers or in strange places.
（2022·北京朝阳·统考一模）How much time do you spend doing research before you make a big decision There are people who go over every detail exhaustively before making a choice, and it is certainly possible to overthink things. But a fair number of individuals are quick to jump to conclusions. Psychologists call the latter a mental bias (偏见). In this case, the error is making a call based on the least of evidence.
A research by Carmen Sanchez, a professor at the University of Illinois, and David Dunning, a professor at the University of Michigan, has found that hasty judgments are often just one part of larger error-prone patterns in behavior and thinking. These patterns have costs. People who tend to make such jumps in their reasoning often choose a bet in which they have low chances of winning instead of one where their chances are much better.
To study jumping, researchers did an experiment to examine decision-making patterns among 600 people from the general population. They applied a thinking game, in which players encountered someone who was fishing from one of two lakes: in one lake, most of the fish were red; in the other, most were gray. The fisher would catch one fish at a time and stop only when players thought they could say which lake was being fished. Some players had to see many fish before making a decision. Others—the jumpers—stopped after only one or two. Participants were also asked questions to learn more about their thought patterns. It was found that the fewer fish a player waited to see, the more errors that individual made in other types of beliefs, reasoning and decisions.
So what is behind jumping Researchers commonly distinguish between two pathways of thought: automatic, known as system l, which reflects ideas that come to the mind easily, spontaneously and without effort; and controlled, or system 2, consisting of effortful reasoning that is analytic, mindful and intentional. It was found that jumpers and non-jumpers were equally influenced by automatic thoughts. The jumpers, however, did not engage in controlled reasoning to the same degree as non-jumpers. It is system 2 thinking that helps people counterbalance mental biases introduced by system 1. A lack of system 2 thinking is also more broadly connected to their problematic beliefs and faulty reasoning.
In everyday life, the question of whether we should think things through or instead go with our heart is a frequent and important one. Recent studies show that even gathering just a little bit more evidence may help us avoid a major mistake. Sometimes the most important decision we make can be to take some more time before making a choice.
29．What is the main idea of the first two paragraphs
A．Overthinking things is a mental bias.
B．Evidence is a necessity for judgments.
C．Jumping results from a wish to win a bet.
D．Jumpers have a tendency to a mental mistake.
30．What can we learn from the experiment
A．Jumpers caught more fish than non-jumpers.
B．Non-jumpers gave quicker answers than jumpers.
C．Non-jumpers tended to see more fish before naming the lake.
D．People who saw fewer fish made fewer mistakes in reasoning.
31．According to the passage, in which situation is system 2 engaged more
A．After comparing different brands and models, David purchased a car.
B．On hearing that the Apollo moon landings were faked, Mia believed it.
C．Seeing the dirty windows of a restaurant, Mary decided its food was bad.
D．When picking a doctor, Jim merely accepted the recommendation from a friend.
32．What does the author intend to tell us
A．To reflect on our thought patterns regularly.
B．To think twice before we make our decisions.
C．To realize the consequences of faulty reasoning.
D．To adopt two pathways of thought before acting.

（2022·北京朝阳·统考一模）I first discovered the Little Free Library concept while being on a 2015 vacation in Santa Barbara, California. I fell in love with the idea of free literature-sharing boxes posted at the edges of parks and along sidewalks in neighbourhoods. And because our home was already filled with mountainous piles of books, my husband wasn’t the least bit surprised when I suggested starting a Little Free Library of our own. In our garden shed (棚) , we filled the shelves with books from our personal collection. Over the next two months, strangers discovered our Little Free Library and began their regular visit.
My love of reading dates back to 1970, when I studied in a three-room primary schoolhouse on a dirt road. One day, I accidentally came to the basement library and I was fascinated by the picture books. Unfortunately, the books were later thrown away when the school discovered the basement was full of mould (霉). Happily, weeks later, a truck arrived with a trailer—which, with the help of our county’s public library, had been transformed into a paradise (乐土) for those who enjoyed reading. Now I still remember the floor-to-ceiling shelves and the carpeted benches in it. Every time I left, I wrote my name on several sign-out cards, which were filled with names of children from neighbouring schools. We liked the same books and, although we never met, I considered them friends.
At the beginning of the first COVID-19 lockdown, our Little Free Library began to include children’s stories. I witnessed mothers lifting their children for a look into the library. Walkers included our street in their route so they could check for new offerings. Some folks routinely drove from several blocks away to visit. From time to time, visitors filled shelves with literary fiction, romances, poetry and a range of non-fiction. I smiled when people met me in the yard and commented that our Little Free Library was like a bird feeder.
We remain grateful that we have kept our Little Free Library open. It has become an alternative means of creating a community of people with mutual regard for humanity and the written word. We are together even when apart.
36．What inspired the author to start the Little Free Library
A．Her large collection of books. B．An experience during a vacation.
C．Her husband’s encouragement. D．Strangers’ visit to her garden shed.
37．From the passage, we can learn that________.
A．neighbouring schools donated books to the Little Free Library
B．the author’s enthusiasm for reading started from her childhood
C．children wrote their names on the sign-out cards to meet friends
D．the county’s public library became a perfect place for book lovers

（2022·北京朝阳·统考一模）Both misinformation, which includes honest mistakes, and disinformation, which involves an intention to mislead, have had a growing impact on teenage students over the past 20 years. One tool that schools can use to deal with this problem is called media literacy education. The idea is to teach teenage students how to evaluate and think critically about the messages they receive. Yet there is profound disagreement about what to teach.
Some approaches teach students to distinguish the quality of the information in part by learning how responsible journalism works. Yet some scholars argue that these methods overstate journalism and do little to cultivate critical thinking skills. Other approaches teach students methods for evaluating the credibility of news and information sources, in part by determining the incentive of those sources. They teach students to ask: What encouraged them to create it and why But even if these approaches teach students specific skills well, some experts argue that determining credibility of the news is just the first step. Once students figure out if it’s true or false, what is the other assessment and the other analysis they need to do
Worse still, some approaches to media literacy education not only don’t work but might actually backfire by increasing students’ skepticism about the way the media work. Students may begin to read all kinds of immoral motives into everything. It is good to educate students to challenge their assumptions, but it’s very easy for students to go from healthy critical thinking to unhealthy skepticism and the idea that everyone is lying all the time.
To avoid these potential problems, broad approaches that help students develop mindsets in which they become comfortable with uncertainty are in need. According to educational psychologist William Perry of Harvard University, students go through various stages of learning. First, children are black-and-white thinkers—they think there are right answers and wrong answers. Then they develop into relativists, realizing that knowledge can be contextual. This stage is the one where people can come to believe there is no truth. With media literacy education, the aim is to get students to the next level—that place where they can start to see and appreciate the fact that the world is messy, and that’s okay. They have these fundamental approaches to gathering knowledge that they can accept, but they still value uncertainty.
Schools still have a long way to go before they get there, though. Many more studies will be needed for researchers to reach a comprehensive understanding of what works and what doesn’t over the long term. “Education scholars need to take an ambitious step forward,” says Howard Schneider, director of the Center for News Literacy at Stony Brook University.

（2021·北京朝阳·统考二模）A Bridge Linking Art and the Audience
According to a 2018 report, people aged between 16 and 24 make up about 15 percent of the population but only 10 percent of museum-goers. Similarly, people aged over 35 go half as much as you would expect from their population size. We have reached the point of recognising the disconnection between art and the audience but haven’t yet determined how to bridge the gap. Two answers to tackling this challenge lie in telling a greater diversity of art histories and communicating these stories in more accessible ways.
In 2018, a radio program called Art Matters was started with the aim of discussing art from a pop-culture viewpoint with topics that would engage younger and more diverse audience. It offers an accessible pathway to art history with conversations on different topics. Art history is about storytelling; art content shines when there is an effort to bring audience along for the discussion.
More traditional institutions are paying attention. Recently the Getty Museum issued a social-media challenge for people to recreate paintings using items they had at home. Users displayed incredible creativity, and the museum was flooded with submissions. This reaction proves that there is a potential desire for the audience to engage with art topics if the format is appealing. Since many people feel intimidated and think that there’s a base level of understanding required to join the conversation, the Getty initiative serves as a reminder that there are many pathways to engaging with it.
Another result of the Getty challenge was the exposure given to a diversity of artworks. The famous opera singer Peter Brathwaite, for example, made scores of attractive recreations highlighting centuries of black paintings. His efforts opposed the idea that there were not many historical paintings of black figures. It is extremely important that we do a better job of showing the complex and diverse stories that are represented in art.
Social media have offered a platform for people who have not traditionally had a seat at the table. Anyone can recognise a gap in the field and address it. Accounts have gathered tens of thousands of followers. They are the proof that there is hunger to hear these art histories, and these themes work brilliantly for museum programming.
But there is only so much that can be done without the museums and galleries changing meaningfully from within. We need to see a better balance of these stories represented in permanent collections. We also need a much wider diversity of people and interests represented on board. Ensuring that art-and writing and talking about art-is able to continue on the rising generation of storytellers, inside and outside of institutions, getting the funding and support they need to paint a brighter picture for the part.
43．What challenge is the author trying to tackle
A．People doubt a great diversity of artworks.
B．Fewer and fewer young people go to museums.
C．Art appears too distant from common audience.
D．Adult audience has a different understanding of art.
44．What does the underlined word “intimidated” in Paragraph 3 probably mean
A．Tired. B．Worried. C．Annoyed. D．Surprised.
45．In the author’s opinion, the museums and galleries should ________.
A．make the art history stories accessible in a traditional way.
B．change meaningfully for activities like the Getty challenge.
C．limit the number of storytellers both in and out of institutions.
D．improve the permanent collections by adding famous artworks.
46．We can conclude from the passage that common audience ________.
A．lacks the channels to understand and talk about art history.
B．prefers to view artworks and hear art stories on social media.
C．feels satisfied with people and interests represented on board.
D．refuses to engage with diverse art topics and art history stories.
（2021·北京朝阳·统考二模）The Rise of Voice Technology
Voice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.
Writing with your voice raises several interesting questions. How difficult is it actually Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.
Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.
To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases where the software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.
To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.
Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.
47．According to the passage, which helps to turn speech into writing in terms of style
A．There is careful planning in advance.
B．Errors and broken sentences are avoided.
C．People type words as fast as they say them.
D．The writing contains more prepared phrases.
48．To achieve better results, the author mentions some changes for ______.
A．processing errors in a column.
B．adding minor punctuation marks.
C．increasing the number of brief notes.
D．integrating short paragraphs in writing.
49．The author suggests that ______.
A．human brains are responsible for poor dictated writing.
B．writing with voice promises to improve the quality of writing.
C．writing is an unnatural act that can hardly be learned and improved.
D．technology has a long way to go in the human-computer voice interaction.
50．What is the passage mainly about
A．Why people fully intend to turn speech into writing.

C．Where the human-computer voice interaction is at an advantage.
D．How voice technology enables the change from speech into writing.
（2021·北京朝阳·统考二模）My Biggest Challenge
As a writer on an adventure sports magazine, I’d always fought shy of doing the adventurous stuff myself, preferring instead to observe the experts from a safe distance and relay their experiences to readers in the form of written language. Thus, when I was challenged to take part in a mountain climb in aid of raising money for charity — and to write about it afterwards — I was unwilling, to say the least.
I was lucky enough to have a brilliant climbing coach called Keith, who put me through my paces after my daily work. He gave me knowledge about everything from the importance of building muscle groups to how to avoid tiredness through nutrition. It quickly became apparent that the mechanics of climbing were more complex than I had imagined. There was the equipment and techniques I’d never even heard of, all of which would come in handy on the snow-capped peak I’d be climbing.
Aware of the challenge, Keith made a detailed action plan and I forced myself to stick to it, doing a daily workout at the gym and going on hikes with a heavy pack. I perfected my technique on the climbing wall and even went to climb the mountains to get vital experience. My self-belief increased alongside my muscle power and I became confident about finishing the climb.
All too soon I was on a plane to my destination. On that day, when I looked up at the mountain, I thought of abandoning it. But then I remembered all the hard work I’d done and how disappointed Keith would be if I gave up at the last minute-not to mention letting down the charity and the sense of failure I’d experience myself. With a deep breath I gathered my equipment and headed out into the sunshine to meet the rest of the group.
And as I sit here now, tapping away on my laptop, I’m amazed at the details in which I can recall every second of the climb: the burning muscles, the tiredness, the minor problems along the way. Could I have been better prepared Possibly. Would I be back for another go Thankfully not. The feeling of being excited when I stood on top of the world is a never-to-be-repeated experience but one I will enjoy forever nevertheless.
51．At the beginning of the activity, the author revealed his ______.
A．disappointment in the coming adventure.
B．expectation of writing about his experience.
C．lack of enthusiasm for the challenge he’d been offered.
D．curiosity about taking part in the mountain climb for charity.
52．What did the author realise during his climb training
A．The knowledge about climbing was really confusing.
B．The equipment was the key factor to reach the peak.
C．Climbing was much more complicated than expected.
D．Hard training was far more important than making plans.
53．How did the author feel after he succeeded in climbing the mountain
A．He was relieved that he wouldn’t have to do it again.
B．He was well satisfied that he had done his best for it.
C．He was surprised that he had managed to complete it.
D．He was regretful that it wasn’t as smooth as imagined.
（2021·北京朝阳·统考二模）Sevenhugs HugOne
Do you want to improve the quality of your sleep Sevenhugs has created HugOne that tracks different sleep patterns to help families consistently rest better. There are dozens of devices and tools devoted to monitoring the sleep. But, HugOne is the world’s first family smart home sleep system, which integrates a calculation rule for sleep patterns of children and adults.
HugOne is a well-designed product, full of a sense of science and technology. It connects to a number of smaller sensors called “minihugs”, which are placed on the edge of each bed. They monitor the sleep patterns and other data coming from the person sleeping in that bed. The data are then sent to an app on the smartphone.
● The benefits of HugOne include:
* Having a smart alarm clock on the app as HugOne learns your sleep cycle and automatically sets and sounds to when the best moment in your sleep cycle is identified.
* Monitoring temperature and humidity in your bedroom as well as indoor air quality for the main living space.
* Linking with smart lamps and thermostats, allowing users to fall asleep with sunset light and preferred nighttime temperatures, and wake up to sunrise light and preferred daytime temperatures.
* Ensuring safety from electronic transmissions when you sleep-when the minihug senses a presence in bed, it shuts off its electronic transmissions and starts recording sleep data and sending them to the app.
● The following are selected from customers’ comments:
I prefer HugOne, since it’s convenient to use. I simply place the minihug in the corner of my bed under the sheet and it goes to work monitoring my sleep cycle. It’s really good.
—Robert Compton
● HugOne available for purchase includes:
I think HugOne is a humanized product. It’s shareable, and I’ve connected eight minihugs to the HugOne base in my house. All my family members think highly of it.
—Chris Hanawalt
HugOne will provide maximum protection for your sleep. If you want to get more detailed information, please call the sellers at 1-800-576-1899 or visit .

（2021·北京朝阳·统考一模）What animal pulls at your heartstrings—a panda or a toad (蟾蜍) Zoologist Lucy Cooke draws attention to some of the world’s least attractive animals. She hopes to show the world why some of the most unlovable animals are actually the most interesting and deserving of our attention and protection.
Cooke’s blogs and online videos bring her unusual storytelling style to a serious message: If we only care for the best loved animals, other important parts of the web of life could be ignored. There are so many television shows about lovely animals like koala bears and kittens, she observes. All the attention seems focused on “celebrity” animals. “Those unusual creatures attract me because they tell an amazing evolutionary (进化) story,” Cooke said. “I’m interested in all of nature, not just the shiny bits.”
Amphibians—animals like frogs that live both on land and in water—top Cooke’s list. Over a third of amphibians are going extinct; it’s the worst extinction crisis since the dinosaurs were wiped off the planet. “Amphibians occupy a crucial spot in the middle of the food chain. If you remove them, everything else will be lost as well,” she noted. “That motivated me to start my blog, The Amphibian Avenger. When amphibians go extinct, birds and snakes that eat them also disappear. And since they breathe through their skin, they are easily attacked by pollution and climate change. That makes them fantastic instruments for measuring the health of ecosystems.”
One of Cooke’s most popular online videos is about sloths—extremely slow-moving animals that live in trees. They’ve always had a reputation for being lazy and stupid. In fact, “slothfulness” is the key to the animal’s success, allowing the sloth’s liver (肝脏) to process poisonous substances found in the leaves it eats. Moving slowly also keeps it hidden from enemies. “My video showed the world how interesting they are,” Cooke said.
The bats, dung beetles and more get their moment in the sun thanks to Cooke. “I just want people to share my sense of amazement and love for these creatures.” Cooke stated. “Once you understand why they’re ugly or odd, you’ll appreciate them and want to save them as much as I do.”
57．Cooke started The Amphibian Avenger in order to ________.
A．make the animal popular with people
B．show her unique appreciation of beauty
C．introduce the research on a new species
D．explain the importance of this kind of animal
58．Cooke’s video about sloths is an example of ________
A．why some animals deserve their reputation
B．why she thinks it necessary to save animals
C．how people focus on some specific animals
D．how she is trying to change people’s minds
59．What is the best title of the passage

（2021·北京朝阳·统考一模）Lessons in the Lost Art of Listening
When was the last time you listened to someone And when was the last time someone really listened to you I once asked people what it meant to be a good listener. The typical response was a blank stare.
Of course, technology plays a role. People find phone calls interrupting them, preferring text or wordless emoji. Besides, schools and colleges rarely offer classes or activities that teach careful listening. You can join clubs to perfect your public speaking, but who attempts to achieve excellence in listening The loud unpleasant mixture of sounds of modern life also stops us from listening.
Generally, listening goes beyond simply hearing what people say. It also involves paying attention to how they say it and what they do while they are saying it, in what context, and how what they say is related to you. It’s not about merely holding your peace while someone else holds forth. Quite the opposite. A lot of listening has to do with how you respond—the degree to which you facilitate the clear expression of another person’s thoughts and, in the process, have a clear mind of your own.
Good listeners ask good questions. They engage in exploring the topic, not to divert attention. There are curious questions like “Wouldn’t you agree… ” or “Don’t you think… ” These questions have strong tendencies. They will greatly influence the other person to change his or her view. And you’d better stay away from some personal questions like “What do you do for a living ” or “What part of town do you live in ” Just try to find out what excites people. Ask about the last movie they saw or for the story behind a piece of jewelry they’re wearing. Also good are expansive questions, such as, “If you could spend a month, where would you go ” Research indicates that when people who don’t know each other well ask each other this type of question, they feel more connected than if they spend time together achieving a task.
Because our brain can think a lot faster than people can talk, be careful with the tendency to take mental side trips when you are listening. Smart people’s attention is easily taken away by their own runaway thoughts. They may also assume they already know what the other person is going to say.
The reward of good listening will certainly be more interesting conversations. Researchers have found that attentive listeners receive more information from speakers, even when they don’t ask any questions. We are, each of us, the sum of what we attend to in life. The gentle voice of a mother and the criticism of a boss both ultimately form and shape us. And to listen poorly, selectively or not at all limits your understanding of the world and prevents you from becoming the best you can be.
60．One of the factors that influence listening is that ________.
A．our confidence in listening is decreasing B．our speech creates a lot of noise around us
C．listening skills are seldom taught in school D．texting causes a better effect than phone calls
61．What does Paragraph 3 mainly talk about
A．Why the art of listening gets lost by itself. B．Why effective methods are used in listening.
C．How people make themselves well understood. D．How people can reclaim the lost art of listening.
62．According to the author, what should people do when they are listening
A．Avoid being absent-minded. B．Come up with curious questions.
C．Focus on the speaker’s personal information. D．Try to find common interests with the speaker.
63．What can be inferred from the passage
A．Listening and speaking deserve equal attention.
B．Good listeners maximize the benefits for themselves.
C．Bad listening ultimately contributes to people’s failure.
D．Listeners’ clear mind facilitates speakers’ expression of thoughts.
（2021·北京朝阳·统考一模）The Land Under the Sea
Ten thousand years ago, as the last ice age ended, sea levels around the world were far lower than they are today. Much of the land under both the North Sea to the east of Britain and the English Channel which now separates France and Britain was part of a huge region of forests and grassy plains. Then the climate gradually became warmer and the water trapped in large masses of ice was released.
Now the development of advanced sonar (声呐) technology, known as bathymetry, is making it possible to study this flooded landscape in extraordinary detail. A special echo (回声) sounder is fixed to the bottom of a survey ship and it makes wide sweeps across the seabed. While previous technology has only been able to produce two-dimensional images, bathymetry can now use computers, satellite-positioning equipment and special software to create accurate and remarkably detailed maps. For the first time, an ancient riverbed jumps out of the three-dimensional image. The site of pre-historic settlements can now be pinpointed.
According to expert Linda Andrews, this technological development is of huge significance. “We now have the ability to map the seabed as accurately as we can map dry land,” she says.
Once bathymetric techniques have identified sites where people might have built their homes and villages, divers can be sent down to investigate further. Robot submarines (潜艇) can also be used, and researchers hope they will find stone tools and wood from houses as proof of human activity. The idea shared by many people in Britain of their country as a natural island kingdom will be challenged by the findings: Britain has been inhabited for about 500,000 years and much of this time it has been linked on and off to continental Europe. It remains to be seen how far this new awareness is taken on board, however.
In fact, the use of bathymetry will not be limited to the study of lost landscapes and ancient settlements. It will also be vital in finding ships that have been destroyed in accidents. In addition, commercial applications are a real possibility. Aggregates (骨材) for the construction industry are becoming increasingly expensive, and bathymetry can be used to identify suitable sites for digging for this material. Mapping the seabed will also identify places where rare plants and shellfish are living. Digging at such sites should be prevented, either to work for a profit or to make deeper waterways for massive container ships.
64．How does bathymetry work
A．It has an echo sounder placed on the seabed.
B．It makes use of a number of different devices.
C．It produces two-dimensional images of the sea floor.
D．It bases its calculations on the location of construction sites.

A．Occupied. B．Adjusted.
C．Rebuilt. D．Discovered.
66．The author believes a better understanding of the settlements on the seabed may ________.
A．attract investment in the research under the sea
B．inspire people to take an interest in modern technology
C．adapt the attitudes of the British to their country’s history
D．receive confirmation of rebuilding ancient man-made objects
67．We can learn that the use of bathymetry will help to ________.
A．identify new species of plants and animals
B．provide the precise location of sunken ships
C．evaluate the cost of seeking certain resources
D．promote the development of deeper waterways

All of these roles, though, depend on their unchanging colouration. This plays into the idea that butterfly wings are dead tissue, like a bird’s feathers. In fact, that’s not true. For example, in some species males’ wings have special cells releasing some chemicals which attract females.
