2020-2021学年中国人民大学附属中学西山学校高三英语第四次联考试题及答案解析

2020-2021学年中国人民大学附属中学西山学校高三英语第四次联考试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ACharlie Thorne and the Last Equationby Stuart GibbsThe CIA is on a task to find an equation (方程式) called Pandora, which could destroy the world if the wrong people get it. For help, they turn to Charlie, a 12-year-old girl who's as smart as Albert Einstein. People who like action-packed mysteries will enjoy reading this exciting book.AstroNutsby Jon Scieszka and Steven WeinbergIn AstroNuts, the Earth has been destroyed by humans for thousands of years. Four animals set out from Mount Rushmore, the headquarters (总部) of NNASA. Their task is to find a new planet fit for human life. Finally, they discover one: Plant Planet. The story's theme (主题) is simple: Don't harm the planet. Readers who love fantasy will enjoy AstroNuts.Stargazingby Jen WangChristine hears that Moon, who's new in town, is the kind of kid who beats people up for fun. But Moon and her mum come to live with Christine's family, and the two kids become best friends. Moon even shares a big secret with Christine. Stargazing is based on author Jen Wang's experiences as a child. The story is about the power of friendship and how people are able to change.Roll with Itby Jamie SumnerRoll with It is a story about a 12-year-old girl named Ellie. She has difficulty walking on her own and uses a wheelchair. When Ellie and her mum move to another state to take care of Ellie's grandpa, she must learn to navigate (处理) a new school and new friendships. This page-turner is a must-read for everyone. It's a heartwarming story that really shows the value of familyand how being different is special.1. Which book tells readers to protect the place we live in?A.AstroNutsB.Stargazing.C.Roll with It.D.Charlie Thorne and the Last Equation.2. What makes Stargazing different from the other three books?A. It talks about friendship.B. It tells stories about animals.C. It contains lots of scientific knowledge.D. It was written according to the author's experiences.3. What happened to Ellie?A. She had difficulty in making friends.B. She had an accident which left her in a wheelchair.C. She went to a new school and had to start all over again.D. She lost her mum and was taken care of by her grandpa.BThere are three of us in the laboratory: Jules, me and Dr. Leonards. Leonards asks me to sit in front of Jules. As I do, he looks me in the eye and starts to move his face through a series of emotions-happy, confused, surprised, glaring. I'm attracted by his display, feeling delight when hegrinsand feeling serious when his eyes narrow angrily. None of this would be a surprise, of course, if Jules were a human. But he's a robot head on a table.The most special thing is that, consciously(有意识地), there's no mistaking Jules for a real person. Although he has surprisingly realistic skin, his eyes don't fit firmly against his lids, and he has a terrible hairpiece. Yet, as I walk into the room, I experience a complex worry of feeling in his direction. It's not at all like entering an empty space. It's a bit awkward for Jules’ shining false hair. Some unconscious part of me is responding to him as if he's real. This matters, because if we're to one day live comfortably along with robots , an understanding of how we instinctively(本能地) react to them is significant. The study of these issues is the frontier of a new scientific research; human-robot interaction.Jules was built as part of an attempt to understand the emotions that can be communicated by a human. “All the robots we'vebuilt so far don't have that rich emotions. We wanted to build a robotic face, with small motors that mimic(模仿) all the muscles you have, so we could discover what it could express. "Such research is becoming increasingly important, says Dr. Leonards, partly because our rapidly ageing population will soon need the help ofrobots with which they can effortlessly interact.4. What does the author think of Jules?A. He ignored him in his place.B. He didn't treat him as only a robot.C. He was afraid of his being there.D. He mistook him for a real person.5. What is the purpose to build such a robot?A. To help humans of old ages.B. To carry out a scientific research.C. To take the place of human labour.D. To make an interaction with human.6. What doesthe underlined word “grins” mean in Paragraph1?A. Smiles.B. Shakes.C. Worries.D. Cries.7. What may be the best title for the text?A. Human And RobotB. Success Of Making A RobotC. Robot Will Replace ManD. Difference Between Man And RobotCAdvertisers tend to think big and perhaps this is why they're always coming in for criticism. Their critics(批评家)seem to hate them because they have so much money to throw around. Why don’t they stop advertising and reduce the price of their goods? After all, it’s the consumer who pays.The poor old consumer! He'd have to pay a great deal more if advertising didn't create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods is largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway byelaws while waiting for a train? A cheerful, witty advertisement makes such a difference to a dull wall or a newspaper full of the incidents and disasters.We must not forget, either, that advertising makes a positive contribution to our pockets. The fact that wepay so little for our daily paper, or can enjoy so many broadcast programmers is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!Another thing we mustn't forget is the “small ads.” What a tremendously useful service they perform for the community! Just about anything can be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the “hatch, match and dispatch” column(栏目) but by far the most fascinating section is the personal or “agony” column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It's the best advertisement for advertising there is!8. What is the main idea of this passage?A. Advertisements steal money from our pocketsB. The critics get the wrong idea of advertisements.C. Advertisers perform a useful service to communities.D. Advertisements are everywhere.9. What is the attitude of the author toward advertisements?A. He appreciates the role of advertisements.B. He doubts the effect of advertisements.C. He believes what is said in advertisements.D. He complains too many advertisements in daily life.10. Which of the following is Not True?A. The personal or “agony” column makes us know more about human nature.B. The only purpose of advertising is to sell goods.C. A newspaper will cost us more if there is no advertisement on it.D. Advertisement makes our life color1 ful.11. Whicof the following shows the structure of the passage?( ①=" Paragraph" 1, ②=" paragraph" 2, ③=" paragraph" 3, ④=" paragraph" 4 ⑤=" paragraph" 5)A B.C. D.DPreventing heart disease is a topic I think about all the time, given my family history of heart disease. So last summer, I travelled toBolivia.The natives, called the Tsimane, were reported to have the healthiest hearts in the world. I wanted to learn what they could teach me about preventing heart disease.Getting to the Tsimane wasn't easy. They lived in small family groups of about 60 people along river banks. We finally found one of the villages at sunset. That night, we set up our tents in the middle of the village. Thatched huts surrounded us, with no electricity or modem conveniences.At first, I thought they mainly got their calorics from meat. However, I found food such as rice and com made up nearly 70% of their diet. The food was not processed, lacking added sugars or salts.During my stay there, I went hunting and fishing with the men and played soccer with the kids. I found the Tsimane were standing or walking nearly all of their waking hours. Men spent lots of time tracking animals. Fanning and gathering, mostly done by children and women, were all-day affairs.I also got a clear idea of how they rested. As soon as the sun went down, people returned to their huts and went to sleep. And with the call of the cock in the morning, another day began.The lifespan of the Tsimane is actually much shorter than those living in theUS. Various factors, like animal attacks and infections, bring down the lifespan. But up until the day they die, they are often very healthy. While heart disease kills thousands of Americans every year and costs nearly a billion dollars a day, the Tsimane remind us that wealth doesn't necessarily buy health.12. Why does the author pay so much attention to preventing heart disease?A. He dreams of becoming a doctor.B. He wants to teach others about the topic.C. His family members encourage him to do so.D. He was born with a high risk of heart disease.13. Which factors did the author mainly focus on in his research?A. Housing, food and cooperation.B. Diet, activity and rest.C. Physical work, social life and lifespan.D. Group size, family history and consumption14. What was the Tsimane 's sleep-wake cycle mainly based on?A. Natural sound.B. Routine activity.C. Animal behaviour.D. Natural light.15. What might the author advise us to do after his travels inBolivia?A. Take in less sugar and salt.B. Stand less and walk more.C. Eat white meat instead of red meat.D. Live in the middle of the community.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020-2021学年上海师范大学第四附属中学高三英语期中考试试题及参考答案

2020-2021学年上海师范大学第四附属中学高三英语期中考试试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BDepression（抑郁症）in young adult males, ages 18 or 19, is linked to a 20% greater risk of having a heart attack in middle age, according to a new Swedish study.The link can be partly explained by poorer stress resilience（抗压能力）and lower physical fitness among teens with mental disorders.Theresearch included 238,013 men born between 1958 and 1962 who were given examinations in adolescence（青春期）and were then followed into middle age（up to the age of 58 years）. A total of 34,503 men were diagnosed（诊断）with a mental disorder.The study found thata mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.“We already knew that menwho were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.4. How does the author develop paragraph 3?A. By giving examples.B. By listing figures.C. By making a comparison.D. By drawing a conclusion.5. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.6. What will Bergh agree with according to the last paragraph?A. Physical activitiesadd to stress.B. Stress may cause heart disease.C. Taking exercise is unnecessary.D. Staying fit is of great importance.7. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.CI come to theUnited Statesten year ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start.Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself.One day, however, my son told me that he was sad because his friends would come over and I didn’t understand them because I didn’t speak English. He was also sad because I could never help him with his homework. That same day, I told myself, “Rocio, you have to start believing in yourself and you will see you can make it.”The next day, I went downtown to look for a big banner (横幅) in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That’s the way I foundChaffeyCollege. The following Monday, I went to ask for information. They told me that summer school was starting that week.That’s how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had to write a story for school. It was about the female they most admired and why . She wrote that I was the person she most admired because I had started going to College. I will never forget this.8. According to the passage, the author probably is a .A. teacherB. doctorC. fatherD. mother9. What made the author make up her mind to study English?A. What her son said.B. What her daughter said.C. Thinking about herself.D. Thinking about her daughter.10. How did they findChaffeyCollege?A. On the way to the movies.B. They took a new route and got lost.C. Ask a stranger for information.D.

What really changed the author’s life was she believed in herself.D. The author wrote that she was the person her son most admired.D36-year-old Juan Dual likes to joke that he’s empty inside. Juan’s story began when he was only 13. It was then that he was diagnosed with a terrible disease, which left him with a 99.8% chance of developing cancer of the digestive system. At age 19, right after finishing high-school, Juan underwent a tough operation to take away his colon and rectum. Sadly, it was only the beginning. By age 28, Juan’s disease had affected his stomach and gallbladder so he had to go under the knife again.Having just recovered from several serious surgeries, Juan Dual decided to accept the invitation of some friends of his parents and travel to Japan. It was there that things started to change for the better. He didn’t speak a word of Japanese, so he spent most of his time walking his dog. One day, the dog pulled harder, and Juan realized that he was still able to jog, and he started to do just that.Months later, he found himself working in a small, peaceful town in England. There was little in terms of entertainment, but the town was surrounded by hills, so he devoted even more of his time to running. He befriended some like-minded folks and told them what he’d been through, and they seemed amazed at the fact that he was still alive, let alone that he was pushing himself to exercise. That’s when the idea of focusing on motivating others took root in his mind.With the help of Pepa, a nutritionist, Juan Dual slowly relearned how to eat to keep his energy level highenough to sustain him during physical activity. Eight months after his last operation, he finished the Barcelona half marathon in two hours. He then started training for mountain running and ultra-marathons.12. Why does Juan Dual say he is empty inside?A. Because he has no desire for anything.B. Because he doesn’t have much knowledge.C. Because he always suffers from great hunger.D. Because many of his organs have been removed.13. What made Juan Dual aware that he could still run?A. His parents’ support.B. A walk with his dog.C. The idea of challenging himself.D. His quick recovery from surgeries.14. When did Juan Dual decide to inspire others with his story?A. After finishing the Barcelona half marathon.B After being introduced to a nutritionist named Pepa.C. After sharing it with his friends in an English town.D. After making friends with people with similar sufferings.15. Which of the following words can best describe Juan Dual?A. Ambitious and intelligent.B. Inspiring and responsible.C. Unfortunate but determined.D. Confident but stubborn.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Look at career incentive(激励).There are oftensubstantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not toreplicate(复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them -but the amount that doesn’t is too much for comfort.But there are also waysin which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.It’s not like we don't know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls ondeaf ears.Why? Why aren't scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition for tenure grant funding, and support and placement for graduate students. Due to this competition for resources,scientists must be evaluated and compared. How do you tell if someone is a good scientist?An oft-used metric is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system. And certainly, some do—as seen in recent high-profile cases of scientific fraud(欺诈). If malicious fraud is the prime concern, then perhaps the solution is simply heightened alertness.However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.4. Which of the following is TRUE about the general trend in scientific field?A. Scientists are persistently devoted to exploration of reality.B. The research findings fail to achieve the expected effect.C. Hypotheses are modified to highlight the experiments' results.D. The amount of science that does replicate is comforting.5. What doesdeaf earsin the fourth paragraph probably refer to?A. The public.B. The incentive initiators.C. The peer researchers.D. The high-impact journal editors.6. Which of the following does the author probably agree with?A. Good scientists excel in seeking resources and securing research positions.B. Competition for resources inspires researchers to work in a more skeptical way.C. All the credentialed scholars and researchers will not take up university professorships.D. The number of publication reveals how scientists are bitterly exploited.7. According to the author, what might be a remedy for the fundamental problem in scientific research?A. High-impact journals are encouraged to reform the incentives for publication.B. The peer-review process is supposed to scale up inspection of scientific fraud.C. Researchers are motivated to get actively involved in gaming the current system.D. Career incentives for scientists are expected to consider their personal intention.CRecycling plastic has always been a stop-start effort, and the wide variety of plastics we produce, the pollution from waste, and other limitations make recycling an economic(经济) problem. It’s estimated(估计)only 9%of plastic ever created has been recycled. But with the help of a chemical process, Canadian Miranda Wang and her company BioCellection want to change that.Stability is one of plastic greatest qualities and downside. There's limited evidence that some plastics can biodegrade (生物降解)but largely photo-plastics degrade in the sun. It’s a long process, and the truth is that we can only estimate how long it takes. Wang is looking to break the inaction and BioCellection's task is to make most plastic waste recyclable.She outlines two current methods. One is to take plastics like water bottles, wash them, cut them, melt and reconstitute them. “That's a very limited process” she says, due to the requirement that plastics be “clean” . The other, which can handle dirtier plastics and a level of pollution, is called hydrolysis(热解). Intense heat is applied to break down plastics so they can be reused as oils for energy, but “it’s not economical,’’ she says.BioCellection’s solution builds on research from over ten years ago, Wang explains, when a US studydiscovered pure polyethylene powder (聚乙烯粉)could be broken down by a catalyst (催化剂). Wang and her co-founder Jean hit upon a bacterium being able to eat plastic. In the years since, they engineered a comparable catalyst capable of doing the same job, only faster, which even works on plastics no one else can recycle at present. “We have now found a catalyst that is much cheaper than the one that was used before, Wang says.Currently focusing on plastic films like shopping hags, the three-hour process breaks clown plastic into chemicals that can act as the building blocks for more complex plastic products.“Right now we’re able to achieve about 70% transformation from plastic waste material to these chemicals,” she adds, saying they’re working to increase that figure.8. Why has so little plastic been recycled?A. Plastic is chemically stable.B. Recycling plastic led to pollution.C. We produced various plastics.D. Most photo-plastics degrade in the sun.9. What does Wang think of the two current methods?A. Highly effective and dynamic.B. Expensive and pollution-causing.C. Limited and energy-consuming.D. Widely used and recognized.10. What did BioCellection find effective to recycle plastics?A. Polyethylene powder.B. Chemical products.C. Plastic films.D. A catalyst.11. What is the text mainly about?A. Miranda Wang and her company.B. A new plastic recycling method.C. The greatest downside of plastic.D. Transformation of plastic waste.DANew Zealandcouncil has announced a month-long road closure in order to allow a sea lion and her pup to reach the ocean safely.John Wilson Ocean Drive in Dunedin will be closed after the New Zealand sea lions made their home at a nearby golf course and started "regularly crossing the road to get to the beach," according to a Facebook post from Dunedin City Council."You can still visit the area on foot or by bicycle, but please give the sea lions lots of space," continued the post.Locals applauded the decision, and one even called for the closure to be made permanent."No dogs should be on the beach, either," wrote Gaylene Smith. "We need to protect our beautiful sea life."Dogs are known to attack sea lions, and Chisholm Links Golf Course, where the sea lions have made their home, also posted advice to dog walkers in a Facebook update."We're lucky to have sea lions on our coastline and we need to share the space with them,as this is what makes our coastline so unique!" wrote the course on Facebook.The council went on to explain thatNew Zealandsea lions are endangered, and are one of the world's rarest species of sea lion.There are an estimated 12,000New Zealandsea lions left, according to the Department of Conservation. Under local law, anyone who kills a sea lion could face up to two years in prison or a fine of up to NZ$250,000(US$178,000).12. What decision has the Dunedin City Council made?A. Closing an ocean drive for a month.B. Forbidding entry into a golf course.C. Forbidding walking dogs outside.D. Closing the nearby beach temporarily.13.

"We make lip balm, which is kind of like our main product/ says Heath. They also make and sell different body balms, all natural, all handmade, while the profits benefit cancer research. "We've raised S 15,000/ Heath says.And with the great optimism of children, they don't just want to help；they wont to win. We want to find a cure. We want to help doctors find a cure, Harry explains, The brothers are also Gelding a team for the Light the Night Walk, to fight cancer."I think it's great to raise money and help people who have cancer," says Heath. Their parents play a big role as well, but it's the boys who provide the most enthusiasm with a message we can all learn from. "If you want to do something... do it," Harry says.

The longest journey begins with the first step.DOur house was across the street from a big hospital so we rented our spare upstairs room to outpatients (门诊病人). One evening, there was a knock at the door. I opened it to see a truly sick-looking man.His face looked terrible — it was swollen and red. Yet his voice was pleasant. He told me that he came for treatment and that he’d been hunting for a spare room since noon, but no one would give him one. “I guess it’s my face...”For a moment, I hesitated, but his next words convinced me: “I will sleep in this rocking chair on the porch. My bus leaves early in the morning.”The old man had a huge heart inside his tiny body. He told me that he fished for a living to support his daughter, his daughter’s five children and her disabled husband.He didn’t complain while telling me his story. He was grateful that no pain accompanied his disease, which was seemingly a form of skin cancer.The next morning, he said, “Can I come back and stay next time I need treatment?” I told him he was welcome to come again.On his next trip, as a gift, he brought a big fish and some large oysters (牡蛎). In the years that he stayed with us, there was never a time that he did not bring us gifts like these.My neighbour warned me that I could lose potential renters after the old man left.Maybe we did lose renters once or twice. But if they had known him, perhaps their illnesses would have been easier to bear. I know our family will always be grateful to have known him. From him, we learned what it was to accept the bad without complaint and the good with gratitude.12. Why did the author let the old man stay after hesitation?A.

The passage is mainly about ________before you are 18.A. good habits to keepB. skills to haveC. things to doD. sports to playBOne day when I was 5, my mother criticized me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. In my angry motion to open the screen door (纱门) with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no regret, for I was happy to be playing in the backyard with my toys.Today, I know if my child had done what I did, I would have criticized my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. But my parents never said a word. They left the corner of the screen door pushed out, creating an opening, a crack in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would remind me of my mistake from time to time. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. I would wonder if my family members were thinking the same thing, silently blaming me every time a flying insectentered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Aboveall, it has helped me become a more patient person and not burst out so easily.4.

Takes charge of.CA single toy catches a child's attention for a limited period of time, but a box of items that allows a child to build their own toys will catch their imagination for years to come. This brilliant idea already exists in real product form, and it's called Toyi.Toyi is described as an eco-friendly creative building kit, and it recently won the well-known IF Design Award. It came from Istanbul, Turkish, where a young female designer named Elif Atmaca first came up with the idea for it when she wanted to help the kids living in disadvantaged areas. These children do not have access to the variety of interesting toys that wealthier children do.Toyi Atmaca's design allows children to transform what are around them into clever toys. It consists of sticks, junction parts, flexible connectors, toy body parts like feet, eyes, hands, and wheels that can be used to turn old water bottles, cups, boxes, towels, etc. into cute, clever, and unique playthings. This toy kit upcycles(升级利用) materials that would otherwise go to waste, turning a recycling bin into a treasure container.“Our initial target was to deliver Toyi kits to only disadvantaged children in Turkish,” Atmaca told the media. But during a research conducted with around300 children, .she realized that the restriction on being creative went beyond any boundary. “I saw that everything was planned and shaped by grown-ups, blocking the kids' imagination in a significant way,” said Atmaca.Atmaca concluded that each kid needed space where he or she could freely create. She explained the entire process should be left to kids’ creativity, reminding teachers and all grown-ups that child-led play was an excellent way for children to develop lifelong skills.Toyi's creators are now considering distributing the kits to as many children as possible around the world through different international NGOs. Atmaca notes that for each Toyi kit sold out, they will also donate one kit toa disadvantaged child through different partnerships around the world.8. Why did Atmaca design Toyi at first?A. To win the famous IF Design Award.B. To help poor kids make their own toys.C. To protect the environment in Istanbul.D. To recycle all the waste in the dustbin.9. Which is probably the product made with the toy kit of Toyi?A. A new picture of a young boy.B. A computer with high technology.C. A treasure container from a dustbin:D. A six-armed “robot” from a water bottle.10. How do the toy kits help improve the children's ability?A. It provides the kids various types of toys.B. It offers space for the kids’ creative minds.C. It changes the poor kids' living conditions.D. It teaches the kids to share joys with others.11. What is the new target for Atmaca and her partners?A. Donating toykits to more poor children.B. Selling toy kits to every kid in the world.C. Designing new toy kits for kids and adults.D. Doing further research on the kids' demands.DThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initiallyconsist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years.

Why do children would like to visit Regency Square Shopping Center?A. they can make many friendsB. they can take the mini train thereC. they can buy a lot of wonderful toysD. they can play their favorite computer games23.This passage is probably taken from _______.A. a textbookB. an advertisementC. a science magazineD. an announcementBIn one of my favorite photographs of my mother, she's about 18 with long, blond hai r. It’s the 1970s and my dad is there, too, hugging her from behind.I haven’t seen this photo for years. I have no idea where it is now, but I still think of it—and, specifically, my mom is in it. She looks so young and innocent. At that time she hasn't yet dropped out of college, or got married. The young woman in this photo has no idea that life will bring her five children and five grandchildren, one divorce, two marriages and a move across the country.For me, as for many daughters, the time before my mother became a mother is a string of stories, told and retold: the time she sold her childhood Barbie doll to buy a ticket to Woodstock; the time she worked as a waitress at Howard Johnson's, struggling to pay her way through her first year at Rutgers. The old photos of her are even more appealing than the stories because they're a historicalrecords carrying the weight of fact.It is always a comfort from those photos to know that time, aging and motherhood cannot take away a woman's essential identity. For daughters who closely resemble their moms, it must be an even bigger comfort: these mothers and daughters are twins, separated by a generation, and an old photo serves as a kind of mirror.For daughters, these old photos of our mothers feel like both a chasm(巨大差异) and a bridge. The woman in the picture is someone other than the woman we know. She is also exactly the person in the photo — still, right now. Finally, we see that the woman we’ve come to think of as Mom —whether she’s nurturing(养育), or disapproving, or thoughtful, or supportive, or sentimental—is also a mysterious, fun, brave baby.She’s been here all this time.24. What can we know about the author's mother from paragraphs 2&3?A. She was good at storytelling.B. She divorced twice all her life.C. She traveled across the country in her youth.D. Life was tough for her during her first year at college.25. Why does the author find the photo of her mother appealing?A. The photo reminds her of her mother.B. Her mother looks young and happy in the photo.C. The photo tells a lot about her mother in her youth.D. She wonders why her mother dropped out of college.26. Some photos of mothers bring comfort to their daughters because ________.A. the photos are kept well even after generationsB. the photos record the life of the mothers faithfullyC. the photos help daughters to learn more about their mothersD. the photos show the essential part of the mothers remains unchanged27. Which one could be the best title of the passage?A. The Pictures of Our Mothers.B. My Favorite Picture of My Mother.C. Our Mothers as We Never Saw Them.D. The Way to Learn About Our Mothers.CA new device works like a solar panel, except it doesn't harvest energy from the sun. It captures energy from the cold night sky.A prototype(雏形) of the device produced enough electricity at night to power a small light bulb.A bigger version might one day light rooms or charge phones. It could also power electronics in remote or low-resource areas that lack electricity.The device makes use of the temperature difference between the earth and outer space to createelectricity. As long as one side of it is cooler than the other, the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum(铝) plate. That plate is sealed beneath a transparent cover and surrounded with insulation(隔热材料) to keep out heat. The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.Researchers tested a 20-centimeter prototype one clear December night in Stanford University, California. The generator produced up to 25 milliwatts of power per square meter of the device. That was enough power to light a small light emitting diod e(发光二极管)，or a LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. The system might need more insulation around the cool, top plate to do that.“The device could also help power remote weather stations or other environmental devices,”says Aaswath Raman. He is a material scientist who works on the device at the University of California, Los Angeles. “This may be useful in polar regions where people can’t see sunlight for months,” Raman says. “If you have some low-power devices and you need to power them through three months of darkness, this might be a way.”28. What does the author mainly talk about in Paragraph 3?A. Application fields of the device.B. Significant effects of the device.C. The working principle of the device.D. The developing process of the device.29. How can researchers make the device produce more electricity?A. By putting more insulation around the top plate.B. By using it in extremely cold and clear nights.C. By attaching the bottom plate to a warm plate.D. By covering the top plate with a transparent lid.30. What is the limitation with the tested device?A. It won't be expanded to be much larger.B. It fails to produce electricity fast enough.C. It is unable to power small electric lamps.D. It produces a limited amount of electricity.31. What's Raman's attitude to the new device?A. Hopeful.B. Doubtful.C. Negative.D. Ambiguous.DClimate change is taking its toll on one of the world’s coldest places. A study suggests that the Arctic “may be essentially ice-free during summer within 15 years.”The study used statistical models to predict the future amount of Arctic ice, which suggested that the Arctic could be ice-free in the summer during the decade of the 2030s.Sea ice is frozen ocean water that melts each summer, then refreezes each winter. Arctic ice haslong been considered a canary(金丝雀)in a coal mine for climate scientists. Climate scientists believe it is a valuable message showing potential danger. The amount of summer sea ice in the Arctic has been steadily shrinking over the past few decades because of global warming. It reached its second-smallest level on record in 2019. the National Oceanic and Atmospheric Administration (NOAA) said.Sea ice affects Arctic communities and wildlife such as polar bears and walruses(海象), and it is helpful to adjust the planet’s temperature by influencing the circulation of the atmosphere and ocean. ‘The extent of Arctic ice is important to Arctic people, whose lands are being affected by increased coastal loss,”NOAA said in a statement.”However, the disappearance of ice creates economic opportunities, including the opening of oil fields and new shipping routes." What scientists refer to as the first “ice-free”Arctic summer year will occur when the Arctic has less than 1 million square kilometers of sea ice.As the climate changes, the Arctic is warming more than twice as fast as the rest of the planet. Arctic air temperatures were about 3.4 degrees above average in 2019, and were the second-warmest since records began in 1900. Scientists also said the results of the study indicate that the ice may disappear even more quickly than current models suggest.32. Which year will see an ice-free summer most likely?A. 2030.B. 2035.C. 2040.D. 2045.33. Which i s closest in meaning to the underlined phrase “a canary(金丝雀) in a coal mine” ?A. A danger.B. A conclusion.C. A disaster.D. A warning.34. What can we infer from Paragraph 3?A. The disappearance of sea ice can be double-edged.B. Sea ice has created many economic opportunities.C. Sea ice does good to Arctic people and wild animals.D. The planet’s temperature adjusts the atmosphere and ocean.35. What is the text mainly about?A. Climate change causes ice melting.B. The Arctic may face ice-free summers.C. Sea ice has affected the Arctic greatly.D. Arctic ice is disappearing quickly.第二节：（共5小题；每小题2分，满分10分）根据对话内容，从对话后的选项中选出能填入空白处的最佳选项。
