2023-2024学年江苏省无锡市青山高级中学高一上学期期中考试英语试卷When I woke up, I made myself breakfast, sat and listened to the traffic. Some of my friends ask me how I can stand living somewhere so noisy. It’s true that there’s always some kind of noise in my neighborhood, but to me, these are the sounds of life.It was Saturday morning, so I decided to go to the park. The taxi is the fastest way to go but I took the bus instead.When you ride the bus, you get to see so much more of the city. It can be kind of loud on the bus, with some people talking on their phones, others chatting with their friends, and others playing music. It’s just like the traffic’s sounds, though the noise on the bus represents people w orking, relaxing and living.Once I got to the park, I picked a bench over near the play area where kids play while their parents sit nearby. I can see and hear almost everything from there. People-watching is one of my favorite things to do. However, I li ke listening even better. The only problem is that there’s so much to see and hear in the park!Usually, I like to close my eyes. That way, I can pay more attention to the sounds and not get distracted by what I see. With my eyes closed, I could pick out p arts of two old men’s conversation. One of them was telling the other about something his grandson said. I couldn’t hear the rest, but it must have been hilarious because his friend’s laugh was so loud.When I’m old, I hope that I too will have a friend wh o will sit in the park with me, and who will enjoy listening to the sounds of the city as much as I do.1. Some of the author’s friends think “the sounds of life” are very ______.A．unpleasant B．unique C．magical D．interesting2. The author took the bus to the park because ______.A．there was no other transport to go there B．he wanted to see more about people’s life C．it was the most convenient way D．his friend advised him to do so3. The author closed his eyes in order to ______.A．have a good rest B．hide himself from viewC．enjoy the sounds of life D．avoid talking with the two old men4. The underlined word “hilarious” in Paragraph 5 probably means “______”.A．truly different B．quite popular C．rather strange D．extremely funny 5. What’s the author’s hope according to the last paragraph?A．Getting rid of the noise. B．Living in a quiet neighborhood.C．Sitting in the park. D．Enjoying the sounds of a city with afriend.Ida Keeling’s daughter, Cheryl, a lifelong athlete, thought that maybe what would pull her mother out from under her dark cloud was something that would get her pumping again. She suggested a run. Not just a jog around the block, but an official run. At the time, Ida Keeling was 67.Keeling had grown up poor in Harlem, and had done hard work in factories. She had lost her husband early to a heart attack, and two of her four children—both of her sons— died in unsolved drug-related incidents in 1978 and 1981.Keeling had sunk into a deep depression (消沉), and her health had begun to slide. Her daughters began to worry that they soon might be losing their mother as well.It had been decades since Keeling had done any running, and she would later recall that firs t “mini-run” feeling as if it would never end. But when it did, “I just threw off all my bad memories.”She hasn’t stopped running since, and it’s no longer the tough work it was during that first meet. Since then, the small Keeling has set records for 60 meters in the 95-to-99 age group, and in 100 meters for the over-100 group.“I was just exercising,” she says regarding that first run, “and now I'm all over the world.”When she’s not running, she’s working out. She’s in the gym three to four days a week, running on tread-mills (跑步机), working out with weights and pedaling on the exercise bike, and even squeezing in some squats (深蹲) while she’s cooking. Part of her healthy diet is occasional brandy wine mixed with her coffee or water to aid circulation (血液循环).She’s written a book about her experiences, titled Can’t Nothing Bring Me Down: Chasing Myself in the Race Against Time. Her philosophy is also suitable for a runner:“Every day is another day forward.”6. What do the underlined words “get her pumping” mean in paragraph 1?A．Free her from great pressure. B．Fill her with life and energy.C．Equip her with self-confidence. D．Remind her of her problems.7. Why did Keeling suffer from a deep depression?A．She had grown up poor. B．She had done hard work.C．She had been in poor health. D．She had lost her husband and sons.8. What contributes to Keeling’s setting records when she is very old?A．Travelling around the world. B．The mini-run experience.C．Working out whenever possible. D．Brandy wine mixed with coffee.9. Which of the following can best describe Keeling?A．Athletic and strong-willed. B．Caring and sport-loving.C．Friendly and hard-working. D．Humorous and outgoing.10. Which can be the best title for the text?A．Run forward. B．Never too old to learn.C．Live healthily. D．Never give up hope in life.In October, temperatures across China begin to drop. Do you experience a mood shift as it turns to winter?Many people do. For about one in 20 people in the northern half of the United States, cooling temperatures and shorter, darker days may signal the onset of seasonal affective disorder (季节性情绪失调), or SAD, a type of depression that typically arrives in autumn or winter, The New York Times reported.Not every mild blue feeling in winter is SAD. SAD symptoms (症状) make it difficult for people to function. It tends to start with an increased appetite for foods like French fries or ice cream, the eagerness to sleep longer hours, difficulty getting up in the morning and feeling wiped out at work, according to Wales Online.The exact cause of this disorder remains unknown. But the good news is that because SAD is tied to the changing seasons, “You can predict its onset and ward it off.” Michael Terman, a professor of clinical psychology at Columbia University, US, told The New York Times.“There’s been a fair bit of research since about the 1980s supporting light therapy (疗法) as being effective for seasonal kinds of depression,” psychotherapist Rakhi Chand told The Guardian. But she also advised using this type of therapy under the guidance of a professional.While light therapy is the first recommended treatment for SAD, getting outside regularly can offer other opportunities to sink in some light. “You might want to retreat (撤退) like the hibernating (冬眠) bear, but don’t,” Norman E, Rosenthal, the psychiatrist (精神病学家) whose research team identified and named the disorder in the 1980s, told The New York Times. “Walking outside even 20 or 30 minutes each day could make a huge difference,” he added.Also, instead of giving into sugar longing, it is important to choose foods that are known to boost mood such as dark chocolate, nuts, oatmeal and berries, according to Egypt Today.Too nervous to enter winter? Remember, SAD is seasonal. If winter comes, can spring be too far behind?11. What may signal the onset of SAD?A．Rising temperatures. B．Longer days.C．Shorter days. D．Warming temperatures.12. Which of the following is a SAD symptom?A．Having a reduced desire to eat. B．Finding it difficult to fall asleep.C．Waking up early in the morning. D．Having low or no energy at work.13. What is paragraph 6 mainly about?A．The origin of light therapy. B．The benefits of light therapy.C．The definition (定义) of light therapy. D．Alternatives (替代品) to light therapy. 14. Which of the following is true?A．SAD usually arrives in spring.B．SAD lasts all year around.C．The exact cause of SAD is known.D．Walking outside may relieve the symptom of SAD.15. What is the main topic of this passage?A．Seasonal sadness in winter. B．Increased appetite in winter.C．Longer sleep hours in winter. D．Decreased temperature in winter.In your life, sometimes you may be asked to speak in front of a large group of people. Although it sounds a little scary, even those with stage fright can speak successfully to the group with adequate preparation.Practice your speech before the big day. 16 If possible, practice the speech in front of a friend or family member to get used to saying it to real people. If you feel you must have note cards, limit the amount to about three cards. This will force you to keep your speech brief and help you keep your eyes focused on your audience.Remember why you’ve been invited to speak. If you’re battling fear over speaking to a large group of people, keep your mind on the fact that you were selected for this important role. The speech organizers must have seen something valuable in you or your expertise. 17Remember that fear of public speaking is very common. 18 Most of the people in the audience would be feeling the same fear and stress that you do in your position. Knowing this may make you feel better.19 What you say should be tailored (专门的) to why you’re there and who you’re speaking to in order to avoid sounding general. If speaking to a charity group,mention the good work certain specific individuals have done for the cause. If speaking at a business conference, briefly state why you want to help these people.Keep eye contact with the crowd. 20 Pick one person in each section and look a t him while you’re speaking. After each important point in your speech, switch your focus to another section. When you focus only on one person at a time, the size of the crowd isn’t as frightening.As my husband and I were watering some plants in the yard, a (an) ________ man walking by sopped to talk with us.

Santa Cruz Mission State Historic Park.BAlex Wong, a junior atMarkKeppelHigh SchoolinAlhambra,California, is working hard on his application to a top college. His resume shows off his nearly straight A’s in difficult classes, experience at a summer program atStanfordUniversity, Eagle Scout project and time on the soccer team as well as the school choir. But his steady progress stopped unexpectedly this year. Aiming to open access to college-level Advanced Placement (大学预科) courses, his schoolbegan using a computer-based lottery to give out spaces. Alex got shut out of all three of the courses he requested.The new system caused anger among families whose children failed to get into AP courses, which many consider important to develop advanced skills, improve grade-point averages and allow students to earn college credit, saving them and their families tuition dollars. Students and parents wrote to administrators to complain, circulated a petition (请愿) and launched a Facebook group for trading classes. “I’M DESPERATE! I’LL GIVE YOU FREE FOOD,” one student, Kirk Hum, posted on the 210-member AP Flea Market Facebook group.AP classes have long been held dear by the most talented and ambitious students.But now they are seen as positive for all students who are willing to push themselves – and schools are increasingly viewing access to them as a basic educational right. But this change has brought challenges.Miracle Vitangcol, a junior atDowntownMagnetsHigh Schoolwith average grades and test scores, is failing her AP US history class. She said she can’t handle the rapid pace and volume of material she needs to remember. But she said she intends to stick it out because the class is teaching her to manage her time, take good notes and work hard. “I’m struggling to adjust,” she said. “But I keep telling myself: ‘It’s OK. You can do it. Just push yourself’.”Some critics worry that the open-access movement is pushing too many unprepared students into AP classes, as shown by higher exam failure rates over the last decade. They also fear that open enrollment (录取) policies are encouraging teachers to weaken courses and give out high grades to students who don’t deserve them. “While expanding access is generally a good thing, we need to make sure we’re not watering down the experience for the high achievers,” said Michael Petrilli, executive vice president of the Thomas B. Fordham Institute, a Washington-based educational policy organization.4. The purpose of the new AP courses system at Alex Wong’s school is to ______.A. make sure all students get access to the AP courses they desire.B. ensure that students have a fair chance to get access to AP courses.C. improve the academic performance of students in AP courses.D. separate high achievers from average students through the new courses.5. According to the article, the AP Flea Market Facebook group is a place where ______.A. students’ parents send their complaints to school administrators.B. students share tips about saving money for college.C. students offer items to trade for the AP courses they need.D. students can find support and guidance on their AP study.6. Which of the following statements would Michael Petrilli agree with?A. Opening AP courses to all students is a bad idea.B. School administrators should maintain high academic standards for AP courses.C. High schools should stop charging students for taking AP courses.D. Access to AP courses is necessary for students applying for top American colleges.7. The author used Miracle Vitangcol’s example to show that ______.A. students need to remember too much in their AP courses.B.AP courses pose a big challenge to unprepared students.C. the secret to success in AP courses is to keep pushing yourself.D. average students don’t deserve their places in AP courses.CFairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德).It collects story plotsfrom the Internet and then uses those stories to teach robots how to behave.The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robotwill learn the moral way to behave on that occasion.Quixote would work best on a robot that has a very limited function. It’s a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.8. What function do fairy tales perform in the robots?A. They entertain robots.B. They highlight dangers.C. They make robots more intelligent.D. They enable robots to behave morally.9. What is “Quixote” in the text?A. A punishment systemB. A character in literatureC. A big name in technologyD. A software educating robots.10. What does the designer expect robot to do in the experiment?A. To take advantage of its privilege.B. To finish the task most efficiently.C. To perform in a good mannered way.D. To be rewarded by the storekeeper111. Which of the follow can bestexpress the author’s opinion?A. Robots will definitely have more functions.B. Robots with human’s emotions are perfect.C. Training robots to be socially acceptable is necessary.D. The development of robots is still in a baby step.DThe modern Olympics, which appeared in ancient Greece as many as 3,000 years ago, have become the world’s most important sporting competition. From the 8th century B. C. to the 4th century A. D., the the ancient Olympics were held every four years in Olympia in honor of the god Zeus. The first modern Olympics took place in1896 inAthens, and featured 280 participants from 13 nations, competing in 43 events. Since 1994, the Summer and Winter Olympic Games have been held separately every two years. The 2020 Summer Olympics, delayed one year because of the COVID-19, was held in Japan in 2021.The ancient Olympics were held every four years between August 6 and September 19 during a festival honoring Zeus. The Games were named for their location (位置) at Olympia, a place near the western coast in southern Greece. Their influence was so great that ancient historians began to measure time by the Olympic Games held every four years.After the Roman Empire conquered (征服) Greece in the mid-2nd century B.C., the Games continued, but their standards and quality dropped. For example from 67 A. D., the Emperor Nero entered an Olympic horse race, announcing himself the winner even after he fell off hishorse during the event. In 393 A. D., Emperor TheodosiusⅠended the ancient Olympic tradition.It was another 1,500 years before the Games rose again, largely thanks to the efforts of Baron Pierre de Coubertin (1863-1937) of France. Working hard at the development of physical education, the young man became inspired by the idea of creating a modern Olympic Games after visiting the ancient Olympic building. In November 1892, at a meeting of the Union des Sports Athlétiques in Paris, Coubertin suggested the idea of making the Olympics an international athletic competition held every four years. Two years later, he got the approval (批准) he needed to found the International Olympic Committee ( IOC ), which would become the governing body of the modern Olympic Games.12. What do we know about the modern Olympics?A. The modern Olympics became famous in the 18th century.B. The first Winter Olympics was held in 1994.C. The first modern Olympics dates back to 1896.D. The latest Winter Olympics will delay for two years.13. How often were the ancient Olympics held?A. Every year.B. Every other year.C. Every three years.D. Every four years.14. When did the ancient Olympics end?A. In 393 A. D.B. In 67 A. D.C. In the mid-2nd century B. C.D. About 1,500 years ago.15. What is the best title of the text?A. The ancient OlympicsB. The modern OlympicsC. The Olympics developed through yearsD. The Olympics are popular in modern time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年无锡市青山高级中学高三英语期中考试试卷及答案

2020年无锡市青山高级中学高三英语期中考试试卷及答案第一部分阅读（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AJuanito Estrella has been a housekeeping manager on the US-based large passenger ship Carnival Spirit for 18 months and feels he has found the suitable position in his career(职业). He has always wanted to travel. “I guess I am a really restless spirit.I like traveling, so when the chance came, I jumped at it,” he says.The chance came in the form of a newspaper advertisement for work on cruise ships（游船）. At the time Estrella was the housekeeping manager at a Melbourne hotel. He applied and, after two interviews, a medical check and police clearance, the job was his.Estrella is responsible(负责的)for the cleanliness of the ship, making sure that 160 crew work properly. “I enjoy it because there is no other work-you wake up each day in a different place anda different culture. It’s exciting when you go to the next country and you don’t understand the language,” he says.Estrella likes being busy and getting to know people from all over the world. The 1,000 crew come from 94 countries, and Estrella has learnt Spanish and a little Croatian.But there is adownside. “You cannot get really drunk...because you have safety responsibilities to yourself and others,” he says. “You don’t really think about home.You start to think about home only when you get closer to your vacation and wonder what you’ll be doing.”Life on the ship is anything but cruising. Estrella and his fellows work at least 10 hours a day, seven days a week. He warns the job is not for everybody. “You have to love being busy and be prepared to work every day-and to give up drinking too much alcohol.” In his spare time, if the ship sails into a port, Estrella explores it, otherwise he works out in the crew’s gym, goes on the internet or calls home.1.Which of the following is true?A.He has been a housekeeping manager for 18 months.B.He doesn’t drink wine now.C.He cannot speak a foreign language.D.He used to be a housekeeping manager.2.The underlined word“downside”in paragraph 5 probably means ________ .A.disappointmentB.disadvantageC.failureD.loss3.In the last paragraph, the writer thinks that life on the ship is ________.A.not a tiring journey at allB.just an interesting voyageC.far from a voyage for pleasureD.more than a pleasant travel by seaBScientists have made great discoveries. But how have they influenced our personal lives? Do kids in your classroom even know when Einstein lived? You may be wondering: but why is it important to teachkids about modern-day scientists?First, stories of scientists can encourage kids. Chris Hadfield is a Canadian who went to space, and he’s a real, guitar-playing person. He makes singing videos on YouTube! His story can make kids think scientists are also common people. Hearing scientists’ stories makes kids think “I can do that too!”But not only that, the stories of famous scientists can encourage kids to never give up. Bill Nye was always refused when trying to be an astronaut. But today, he’s made a lot of successes in his role as a popular science educator and engineer. Besides, it’s no secret that scientific discoveries require trying, and trying again.Another way some scientists can encourage kids is through their diversity. Neil deGrasse Tyson, for example, is an African-American, which is not common in his field. Such stories can make kids think anyone can be a scientist.It’s important to know that scientists don’t need to be “gifted” or “good” at school. Often we consider a scientist as being an extremely smart kid at school. That doesn’t have to be true. They just need to have a great interest in science. Telling students stories of scientists can encourage them to show interest in science. As long as they’re interested, they are likely to become a scientist in the future.Modern scientists teach kids that knowledge builds upon the foundation others have laid. This is important — no one can do it alone. Scientists’ stories can encourage today’s young scientists to keep trying. They’ll be encouraged not to give up on the dream of making discoveries. Even if they haven’t made important discoveries, their research may help the following scientists.4. What can Chris Hadfield’s story tell students?A. Scientists are interested in different things.B. Students should have a hobby of their own.C. Scientists can be ordinary like people around us.D. Students should consider scientists as their models.5. Which of the following would the author agree with?A. African-Americans are more likely to become scientists.B. Scientists are not necessarily very smart at school.C. Not all scientists really show interest in science.D. Scientists are usually good at their schooling.6. The last paragraph shows us that ________.A. scientists should help each otherB. a scientist should never give up tryingC. making discoveries is necessary for scientistsD. new scientific discoveries may be based on others’ findings7. What is the text mainly about?A. Why scientists are important to us.B. Why students should be taught about scientists.C. Why students love stories of scientists.D. Why scientists can encourage students.CA 25-year-old American with a university degree can expect to livea decade longer than a peer who dropped out of high school. Although researchers have long known that the rich live longer than the poor, this education gap is less well documented. And although the average American’s expected span(预期寿命) has been smooth in recent year—and, shockingly, even fell between 2015 and 2017—that of the one-third with a bachelor’s degree has continued to lengthen.This gap in life expectancy is growing, according to new research published in the report of the National Academy of Sciences. Anne Case and Angus Deation ofPrincetonUniversityfound that the lifespans of those with and without a bachelor’s degree started to become different in the 1990s and 2000s. This gap grew even wider in the 2010s.What is the link between schooling and longevity(长寿)? Some argue that better-educated people develop healthier lifestyles: each additional year of study reduces the chances of being a smoker and of being overweight. The better-educated earn more, which in turn is associated with greaterhealth.Ms Case and Mr Deaton argue that changes in labor markets, including the rise of automation and increased demand for highly-educated workers, coupled with the rising costs of employer-provided health care, havedecreased the supply of well-paid jobs for those without a degree. This may be contributing to higher rates of alcohol and drug use, suicide and other “deaths of despair”.The authors argued that the educational gap in mortality(致死率) will widenin the wake ofthe covid-19 pandemic. ForAmerica’s overall life expectancy to start climbing again, improvements will be needed across all social groups, not just among the privileged few.8. When did the lifespans of people with and without a degree vary greatly?A. In the 1990s.B. In the 2020sC. In the 2000sD. In the 2010s9. According to the article, changes in labor markets reduce jobs for those without a degree. Which change is NOT included?A. The rising spending of employer-provided health care.B. The gap in life expectancy.C. Raised request for better-educated workers.D. The development of automation.10. What does the underlined phrase “in the wake of” probably mean ?A. afterB. untilC. beforeD. while11. What is the best title for the text?A. Changes in labor market.B. Quit bad habits by Further studyC. Educated Americans live longer.D. Highly-educated people develop healthier lifestyles.DAs artificial intelligence(AI) systems become more advanced, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate(模仿）the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing detailed patient information in quantities is a crucial factor for their success.One of the most important areas for influencing global health is in the field of epidemiology(流行病学）。

Where can kids learn how to protect the environment?A. At Ladder 11.B. At the Block Harbor.C In Green Living Room. D. On a human-sized anthill.BThe race skywards began inAmerica. In the late1800s, industrialization had driven urban populations and land prices up, making tall buildings increasingly cost-effective, according to Carol Willis, director of theSkyscraperMuseuminNew York, “The very first tall buildings were office buildings that concentrated a work force, piled one on top of the other in order to make business very efficient, ”she says.Like all major changes in architecture, the trend wasunderpinnedby engineering. The development of steel framework, which could be used instead of load-bearing stones, made it easier and cheaper to build tall. The coming of the elevator, meanwhile, made living on higher floors far more convenient.Though similar in shape, today's skyscrapers (摩天大楼) look little like those built in the first half of the 20thcentury. This is mostly thanks to architecture's next major technological shift：the curtain wall.Postwar developments in manufacturing meant that huge panes of glass could be produced quickly and uniformly, and glass windows soon became the front of choice for high-rises. As well as allowing for greater floor space and more natural light, glass exteriors (外部) help. buildings resist greater windloads.There are now 191 completed skyscrapers that are at least 300 meters tall. But that doesn't mean our cities will grow taller indefinitely. While each additional story adds sellable floor space, construction costs also rise. All buildings reach a point where adding an extra floor will cost more money than it brings.“Every city wants to have this landmark that gives that sense of distinct culture, ”but it also needs places for people to live and work in urban settings“without the city sprawling (无序扩张), ”explains Hong Kong architect Simon Chan.The next big challenge facing architects goes beyond height：At a time when buildings and their construction account for more than a third of the world's energy consumption and contribute about 40% of greenhouse gas emissions(排放), there are new costs to consider.Whether it's employing more energy-efficient materials, encouraging natural air or using buildingsthemselves to generate solar or wind energy, reducing carbon emissions is the new frontier for many skyscraper architects.4. What does the underlined word“underpinned” in paragraph 2 probably mean?A. Created.B. Prepared.C. Suggested.D. Supported.5. What made living on higher floors much more convenient?A. The development of steel framework.B. Load-bearing stones.C. The use of the elevator.D. The curtain wall.6. What can we know from paragraph 5?A. Our cities will grow taller definitely.B. All skyscrapers are at least 300 meters tall.C. Construction cost rises as the stories increase.D. The profit for builders will be greater as the building becomes higher.7. What's the next big challenge facing architects?A. How to build the greenest building.B. How to build the strongest building.C. How to build the tallest building in the world.D. How to build the most comfortable building.CWe've all heard it before：to be successful, get out of bed early. After all, Apple CEO Tim Cook gets up at 3：45 am, Fiat CEO Sergio Marchionne at 3：30 am and Richard Branson at 5：45 am﹣and, as we all know, "the early bird's catches the worm. "But just because some successful people wake up early, does that mean it's a trait most of them share？And if the idea of having exercised, planned your day, eaten breakfast, visualized and done one task before 8 am makes you want to roll over and hit snooze till next Saturday, are you really doomed to a less successful life？For about half of us, this isn't really an issue. It's estimated that some 50% of the population isn't really morning or evening﹣oriented, but somewhere in the middle. Roughly one in four of us, though, tend more toward bright﹣eyed early risers, and another one in four are night owls. For them, the effects can go beyond falling asleep in front of the TV at 10 pm or being regularly late for work.Numerous studies have found that morning people are more self﹣directed and agreeable. And compared tonight owls, they plan for the future more and have a better sense of well﹣being.Although morning types may achieve more academically, night owls tend to perform better on measures of memory, processing speed and cognitive（认知）ability, even when they have to perform those tasks in the morning. Night﹣time people are also more open and more creative. And one study shows that night owls areas healthy and wise as morning types﹣and a little bit wealthier.Still think the morning people sound more like CEO material？Don't set your alarm for 5 am Just yet. As it turns out, overhauling（全面改革）your sleep time may not have much effect"If people are left to their naturally preferred time, they feel much better. They say that they are much more productive. The mental capacity they have is much broader, " says Oxford University biologist Katharina Wulff. On the other hand, she says, pushing people too far out of their natural preference can be harmful. When they wake early, for example, night owls are still producing melatonin（褪黑素）. "Then you disrupt it and push the body to be in the daytime mode. That can have lots of negative physiological consequence. " Wulff says, like a different sensitivity to insulin and glucose（葡萄糖）which can cause weight gain.8. What does the authordo in the first three paragraph？A. raising the problem→analyzing the problem → solving the problemB. leading in the topic→challenging a viewpoint → discussing about the topicC. presenting a viewpoint → providing supporting proofs→making a conclusionD. introducing a viewpoint →raising the question→presenting author's viewpoint9. What can we know from the 4th and 5th paragraph？A. Morning types tend to have clear goals and better mood.B. To beat night﹣time people ask them to do math calculation in themorning.C. Night owls tend to sacrifice their health for their wealth.D. Neither night owls nor morning persons perform better than the middle ones.10. Which of the following does Katharina Wulff support？A. Don't fall sleep in front of the TV.B. Avoid being regularly late for work.C. Stop setting your alarm for 5 am.D. Better not overhaul your sleep time.11. Why does the author write this article？A. To explain why some people are more successful.B.To compare the differences between early risersand night owls.C. To advise people to get up neither too early nor too late.D. To argue against this view that the Carly bird catches the worm.DWhen I was seven my father gave me a Timex, my first watch. I loved it, wore it for years, and haven’t had another one since it stopped ticking a decade ago. Why? Because I don’t need one. I have a mobile phone and I’m always near someone with an iPod or something like that. All these devices (装置) tell the time — which is why, if you look around, you’ll see lots of empty wrists; sales of watches to young adults have been going down since 2007. This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days all watches tell the time as well as all other watches. Expensive watches come with extra functions — but who needs them? How often do you dive to 300 metres into the sea or need to find your direction in the area around the South Pole? So why pay that much of five years’ school fees for watches that allow you to do these things?If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead the Swiss reinvented the watch, with the aid of millions of pounds’ worth of advertising, as a message about the man wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planesacross the world.Watches are now classified as “investments” (投资). A 1994 Philippe recently sold for nearly £ 350,000, while 1960s Rolexes have gone from £ 15,000 to £ 30,000 plus in a year. But a watch is not an investment. It’s a toy for self-satisfaction, a matter of fashion. Prices may keep going up — they’ve been rising for 15 years. But when of fashion. Prices may keep going up — they’ve been rising for 15 years. But when fashion moves on, the owner of that £ 350,000 beauty will suddenly find his pride and joy is no more a good investment than my childhood Times.12. The author don’t need another watch because ________.A. he don’t like wearing a watchB. he has mobile phone and can ask someone for helpC. he has no sense of timeD. he thinks watches too expensive13. It seems ridiculous to the writer that________.A. expensive watches with unnecessary functions still sellB. expensive clothes sell better than cheap onesC. cheap cars don’t run as fast as expensive onesD. people dive 300 metres into the sea14. What can be learnt about Swiss watch industry from the passage?A. It wastes a huge amount of money in advertising.B. It’s hard for the industry to beat its competitors.C. It targets rich people as its potential customers.D. It’s easy for theindustry to reinvent cheap watches.15. Which would be the best title for the passage?A. Timex or Rolex?B. My Childhood TimexC. Watches? Not for Me!D. Watches----a Valuable Collection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。

2021届无锡市青山高级中学高三语文上学期期中考试试题及答案

2021届无锡市青山高级中学高三语文上学期期中考试试题及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成下面小题。

材料一国家发改委、科技部、工信部等11个部门近日联合印发《智能汽车创新发展战略》，提出到2025年，中国标准智能汽车的技术创新、产业生态、基础设施、法规标准、产品监管和网络安全体系基本形成。

同时，实现有条件自动驾驶的智能汽车达到规模化生产，实现高度自动驾驶的智能汽车在特定环境下市场化应用。

智能汽车是指通过搭载先进传感器等装置、运用人工智能等新技术、具有自动驾驶功能、逐步成为智能移动空间和应用终端的新一代汽车，又称为智能网联汽车、自动驾驶汽车等。

近年来，“智能汽车”一直是极其热门却又停留在试验阶段的话题。

而此次《智能汽车创新发展战略》的发布，让消费者感到，智能汽车真的要来了。

业内人士指出，区别于传统汽车产业，智能汽车具备明显的本地属性，其发展路径与本国的产业特色有关，并受到政策法规、标准体系、基础设施、交通环境等因素的影响。

(摘编自《智能汽车正加速驶来》，2020年3月3日《人民日报海外版》)材料二业界普遍认为，自动驾驶的研发投入动辄以十亿美元起步、其实现周期长达10年甚至更久，加之术业有专攻，“注定”自动驾驶汽车不是单个玩家可以轻松玩转的。

传统车企在汽车市场、整车制造、品牌影响力方面显然有着更加明显的优势，但也需要科技力量来参与这场创新变革。

电动化、网联化、智能化、共享化的“新四化”正在把汽车这个典型的机械产品，转换为一个以机械为载体的电气产品、电子产品、移动智能终端;由一个典型的机械产品转换成由软件定义的机械电子产品。

重新定义的未来汽车正在重塑未来出行。

其中智能网联将成为未来汽车的核心竞争力。

我国互联网企业有极强的技术能力，车企与互联网企业联合是赢得这场汽车革命的重要举措。

另一方面，对互联网科技公司来说，自动驾驶技术的应用和大规模量产，需要整车制造企业的供应链体系，精细化制造及完善的测试评价体系，必须借助车企的能力和平台来实现，最终也是通过实车走向用户。

2021年无锡市青山高级中学高三语文期中考试试卷及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下而的文字，完成各题爹的丧事周福书记对着话筒大声喊，架在大树上的四个大喇叭把他嘶哑的声音传遍全村：“老少爷们儿，疫情严重，大家不要惊慌，科学预防很重要，要做到不串门拜年，不聚会；出门戴口罩，进门勤洗手……”周福的手机响起，他摁了电话，把要宣传的事项讲完。

周福把电话拔过去，弟弟周禄慌张地说：“哥，你赶紧回家，爹病重了！”周福给村主任刘军山交代完事情，急急忙忙地赶回家。

爹睡在火炕上。

周福半跪在爹身旁，握住爹鸡爪样的手。

爹的脸白着，有点儿肿。

周福眼睛发红：“爹，您要好好活着，抱重孙于。

”爹咧嘴笑，声音低沉地说：“你放心，我这老病不咋的，立了春病就缓了。

”周福的手机响起。

刘军山语气很急地说：“书记，你快来第九检测点，几个外地来的人，不听劝阻，硬要进村。

”爹抬起手摆摆：“你去忙吧，挑好村上的担子，你照顾好自己。

”周福掖好爹的被子，掉头出门。

三叔跟出来，叫住周福：“大侄子，大哥这病危险呢，你可要早想办法。

”周福说：“叔，我明白哩，明早带爹去城里医院。

”说着，骑上电动车去了村东头。

一个留平头戴墨镜叼烟卷的胖子高声跟刘军山和两个值班员吵嚷，周福认出是王老二的小儿子王小柱。

这小子在外地搞工程，听说挣了很多钱。

胖子吐一口烟：“我一切正常，回家看我爹，还不行了？”周福说：“大侄子，非常时刻，不行。

村里在西沟口设了隔离室，准备好了米、油、肉。

你们在那儿隔离观察十四天，才能进村。

”胖子狠狠地踹一脚挡路的杆子，跳上越野车，隔窗骂道：“老犟牛！”周福跺脚：“这年轻人，咋这样子呀？”刘军山“呸”一口：“平时对王老二不管不问，过年来显摆了。

”俩人赶往西沟口。

那儿是个养鸡场，年前鸡出栏了，十几间房屋空闲，做了隔离室，从外地来的三家十一口人分开住在里面。

周福和刘军山走进暖烘烘的屋中，男人、女人、小孩和老人像见了亲人般亲热，周福问了他们的吃住，扯了会儿家常，询问还有什么困难。
