Luckily, in the age of social media, we are never truly alone. And with the extra time spent indoors, artists are stepping up to help us all with the following clubs.Drawing from Distance by Sarah Beth MorganLet’s shine some light during this trying time and encourage social distancing! I’m starting this tomorrow myself — but from what I offer, take whatever you please. No rules! Just have fun!Stayathome Art Club byCarsonEllisHello! I’ll be posting art homework here every weekday morning when I can. They’ll be designed for kids and grownups alike. Here is your first homework: Draw a picture of yourself from the shoulders up. You can follow some useful examples. If you want to share or see other people’s self-picture, use these hashtags: #Stayathomeartclub# QACselfportrait30-Day indoor Art by Danielle KrysaOne month of avoiding crowds? I’m in! I challenge you to use this time inside to make one piece every day from now until mid April. Please join me in playing around with some painting ideas that have been rolling around in my head but haven’t found their way onto paper yet. Stay at home, make art, save someone’s life.DIY from Illustoria MagazineWe have been so inspired to see our community come together to provide easy art projects for families during this stay-at-home-time! DIY is actually a fantastic way tosparkyour imagination without breaking a sweat. A video every day will teach you how to DIY something.1. What do we know about Sarah Beth Morgan?A. She is a strict artist.B. She aims at training more artists.C. She prefers to work at home office.D. She will provide a wide range of choices.2. What are you expected to do if you join Stayathome Art Club?A. Hand in homework every day.B. Share other people’s pictures.C. Draw a picture of yourself.D. Show up in person occasionally.3. What does “spark”in the last paragraph probably mean?A. Set off.B. Set down.C. Set aside.D. Set about.BIt is not only praise or punishment that determines a child's level of confidence.There are some other important ways we shape our kids — particularly by giving instructions and commands in a negative or positive choice of words.For example, we can say to a child “Don't run into traffic！” or “Stay on the footpath close to me.” In using the latter, you will be helping your kids to think and act positively, and to feel competent in a wide range of situations, because they know what to do, and aren't scaring themselves with what not to do.Actually, it is all in the way the human mind works.What we think, we automatically rehearse.For example, if someone offered you a million dollars not to think of a blue monkey for two minutes, you wouldn't be able to do it.When a child is told “Don't fall off the tree，” he will think of two things：“don't” and “fall off the tree”. That is, he will automatically create the picture of falling off the tree in his mind.A child who is vividly imagining falling off the tree is much more likely to fall off.So it is far better to use “Hold on to the tree carefully.”Clear, positive instructions help kids to understand the right way to do things.Kids do not always know how to be safe, or how to react to the warning of the danger in negative words.So parents should make their commands positive.“Sam, hold on firmly to the side of the boat” is much more useful than “Don't you dare to fall out of the boat？” or “How do you think I'll feel if you drown？” The changes are small but the difference is obvious.Children learn how to guide and organize themselves from the way we guide them with our words, so it pays to be positive.4. Positive choice of words helps kids to ________.A. learn in different situationsB. do things carefullyC. build up their confidenceD. improve their imagination5. What can we infer from Paragraph 2?A. A child will act on what is instructed.B. One can't help imagining what is heard.C. A child will fall off the tree when told not to.D. One won't think of a blue monkey when given money.6. Which of the following commands helps kids to be safe?A. How do you think I'll feel if you get hurt?B. Don't play by the lake.C. Don't you dare to walk through the red light?D. Fasten your seat belt.7. The main idea of the passage is that ________.A. positive instructions guide kidsB. praise makes kids confidentC right instructions keep kids safe D. clear commands make kids differentCExperts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors inBristolcared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to theBristolEyeHospitalbecause of progressive sight loss.He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it reallyarduousto read, watch TV or recognize faces.”Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too manycertain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”8. What does Dr Denize Atan imply in paragraph 1?A. The diet of the boy is not balanced.B. Fruit and vegetables are rich in vitamins.C. Picky eating is common among teenagers.D. The cause of the boy’s disease is unknown.9. Why did the boy go to see his doctor at the age of 14?A. To improve his poor diet.B. To get some help to lose weight.C. To be treated for his discomfort.D. To slow down his progressive sight loss.10. What does the underlined word “arduous” in paragraph 3 probably mean?A. Important.B. Easy.C. Necessary.D. Difficult.11. What does the last paragraph mainly talk about?A. Reasons why the boy is seriously ill.B.Suggestions for the boy’s family to care for him.C. Advice for parents worried about picky eating.D. Waysof taking in enough vitamins and minerals.DHave you ever been sad because of failure? Please remember, for quite often achieving what you set out to do is not the most important thing.A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can’t finish digging all the way through the earth, but look at what I’ve found during this period!”Theboy’s goal was far too difficult, but it did cause him to go on. And that is what a goal is for－to cause us to move in the direction we have chosen, in other words, to cause us to keep working!Not every goal will be fully achieved. Not every job will endup with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I’ve found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really makes sense.12. The older boys laughed at the boy because he was thought to be______.A. braveB. impoliteC. foolishD. warm-hearted13. Why did the boy show the jar to the older boys?A. To drive them away.B. To show what he had found in digging.C. To show how beautiful the jar was.D. To attract them to join him in the work.14. What can be learnt from the fourth paragraph of the text?A. No dream can come true.B. All work will end successfully.C. Goals shouldn’t be set too high.D. Goals will make us work harder.15. The best title for the text should be______.A. A Boy Dug a HoleB. Joy in the JourneyC. No Pain, No GainsD. Failure Is the Mother of Success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。

2019-2020学年北京市西城外国语学校高三英语期中试卷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ALocated besideLake Geneva, the Olympic Museum houses more than 10,000 artificial objects and hours of interactive contents highlighting some of the best moments during the Olympics. Here are some of the museum’s most moving moments.The Olympic ParkThe journey through the Olympic Museum begins in the Olympic Park, an 8,000-square-meter outdoor area in front of the museum overlooking Lake Geneva and theAlps. The park contains artwork and sculptures that show respect to the world of sport.The first Olympic symbolThe “Olympic Rings” flag was designed by Coubertin in 1913. The rings represent the five continents that participate in the Olympics: Africa, Asia,America,AustraliaandEurope. The six color1 s include at least one color1 that is represented on the flag of every country.The stadiumsThe stadiums that host the Olympic Games are as much of a celebration of design as the games are a celebration of sportsmanship. Guests can explore plans and models of Olympic stadiums’ past and present, including one of the games’ most attractive stadiums, the Bird’s Nest from Beijing 2008 Olympics.The Olympic medalsHave you ever wondered what an Olympic medal looks like? The Olympic Museum has a room that houses every bronze, silver, and gold medal from every Olympic Games dating back to the first modern Olympics of 1896. Each medal design is a unique representation of the year and location in which the games were held.1.Which moment do you see first when exploring the Olympic Museum?A.The Olympic Park.B.The first Olympic symbol.C.The stadiums.D.The Olympic medals.2.What do you know from The first Olympic symbol?A.The first modern Olympics took place inGreece.B.There are six color1 s on the flag of every country.C.Australia used to be the largest continent on earth.D.The “Olympic Rings” flag was created in 1913.3.What can you do in the section of The stadiums?A.Admire the view ofLake Geneva.B.Meet some famous designers.C.Enjoy the model of the Bird’s Nest.D.Talk with guests of honour.BLosing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.After age 50, it’s quite common to have trouble remembering the namesof people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital inBoston.The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrongBut even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion andmemory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive(认知的) reserve, Daffner says.“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways, ” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a known brain booster4. Why does the author say that one needn’t be concerned about memory slips?A. Not all of them are related to one’s age.B. Not all of them are symptoms of dementia.C. They occur only among certain groups of people.D. They are quite common among fifty-year-old people.5. Which memory-related symptom should people take seriouslyA. Totally forgetting how to do one’s daily routines.B. Inability to recall details of one’s life experiencesC. Failure to remember the names of movies or actorsD. Occasionally confusing the addresses of one’s friends.6. What should people do when signs of serious memory loss show up?A. Check the brain’s cognitive reserve.B. Stop medications affecting memory.C. Turn to a professional for assistance.D. Exercise to improve their well-being7. What is Dr. Daffner’s advice forfight against memory loss?A. Having regular physical and mental checkups.B. Taking medicine that helps boost one’s brain.C. Engaging in known memory repair activities.D. Staying active both physically and mentallyCIf you could travel back in time, which period of history would you visit? It’s a great question to ask your friends, and time travel is the subject of many science fiction films. Of course, sci-fi is familiar to most of us, butwhat is cli-fi? The simple answer is climate fiction which focuses on the subject of climate change.Many of the cli-fi examples we watch tend to be disaster films. It could be solar flares (太阳耀斑), ice ages devastating (摧毁) the planet, extreme flooding swamping the earth with water, or super-storms that threaten life as we know it. While films and novels of this style are often subject to the typical images of a hero or heroine battling to save the day, what sets it apart from most sci-fi films is that the plots will often draw on apparently reasonable outcomes in the near future.Climate change and the potential threats have long been established. Some believe that the issue of climate change has even led to more fans watching films to learn more about what's happening to the world – seeing it as a form of edutainment. A study conducted by the Yale programme on Climate Change Communication tested theeffects that two climate fiction novels can have on its readers and found “significant positive effects” in terms of their attitudes and beliefs towards the climate crisis – for example, understanding global warming will harm them and future generations.Most climate films are not only extremely popular action films, but also cause our fear of what some see as the approaching end of the world. This sounds bad, but according to a study conducted on 310 adults in the US, watching such scary films can help us feel more prepared and less alone in situations such as the pandemic (疫情). So, it looks like cli-fi is hereto stay – and there seem to be some benefits. Whether it’s there to educate, entertain or prepare you for a climate crisis, it might have a role to play.8. Which of the following may be the subject of cli-fi?A. Time travel.B. Global warming.C. Weather forecast.D. Economic climate.9. What can we learn about cli-fi films from paragraph 2?A. They are often about extreme natural disasters.B. They want to show that man can conquer nature.C. They usually have similar plots with sci-fi films.D. They can show the true near future of the world.10. Why is the study conducted by the Yale programme mentioned in paragraph 3?A. To prove that climate change has potential threats.B. To show that people like climate fiction novels.C. To tell that cli-fi novels have positive effects on readers.D. To explain how the climate crisis affect the human being.11. What does the writer mainly want to tell us in the last paragraph?A. Cli-fi films are very popular as action films.B. A study was conducted on 310 adults in theUS.C. The pandemic make people scared and alone.D. Cli-fi films are useful and will be here to stay.DI have a memory of being about five years old, picking up a beautiful grilled(烧烤的）cheese sandwich made for me by my hard —working mother and turning it over to see that theother side was burned. Suddenly what I thought was the perfect sandwich was not so perfect. Mom had tried to hide that fact from me. There was noquestion; I ate it anyway without complaining. However, that moment has stuck in my mind for many years. Now, at the age of 43 as a mother of two children and as a biology professor where I am routinely the "academic mother" of hundreds of students every year,I find that I believe inThe Grilled Cheese Principle.Here is what I mean Making a grilled cheese sandwich is easy right? But when I think of how many burned grilled cheese sandwiches I have eaten, or I have made myself, I realize that most of the grilled cheese sandwiches I have known have had at least one burned side. The thing is that although it is a ly easy thing to make, I can also easily lose focus, and before long the sandwich is burned. For my mother, the first side was usually perfect and the second side got burned due to her being distracted. For me,I have tended to burn the first side,but then I more carefully monitor the second side.Either way,the grilled cheese sandwich suffers because it has not been given the attention it deservesSo, I have learned that even the simplest task deserves my full attention. When I am multi-tasking, I am doing none of the tasks well. And when I allow myself to be distracted, I am not in the present moment — not paying attention to the small details of living or enjoying the processSo now, I believe the best way to make a perfect grilled cheese sandwich is to make only one at a time and give it my full attention.12. How did the writer react to the sandwich with burned side?A. She ate it with some complaintsB. She showed no interest.C. She thought it was still perfectD. She was deeply impressed with it13. What doesThe Grilled Cheese Principlemean?A. Even simple things deserve full attentionB. Losing focus makes the sandwich burnedC. Self-made sandwiches are always burnedD. we should make only one sandwich at a time14. Which of the following can we infer from the passage?A. Everything cannot be done well without full attentionB. Moms always like to lie to kids when they have done something wrongC. We can lose focus more easily when we do easy things.D. Multi-tasking can be an obstacle to the achievement of tasks.15. What does the writer mainly want to tell us?A. Nothing is perfectB. Learn to appreciate the burned sandwichesC. Devote yourself to one thing at a time.D. Never do multi-tasks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。

I started my 60s as a bodybuilderand now I'm beginning my 70s as a writer,” she said. “People usually limit themselves by age, and it's discouraging. With age, I remain young at heart.”Dr Susan started bodybuilding at an age when most are considering retirement though she was an athlete from an early age. As a child in Venezuela, she took to gymnastics and later graduated with a physical education degree.Then she obtained a master's degree in education and later a Ph. D. in Adult Personal Development. She taught at Cambridge Rindge and Latin High School in Cambridge, Massachusetts, for 16 years, while raising two daughters.“I started bodybuilding when I met Steve Pfiester, a gym guy who practiced yoga. He invited me to his gym and offered to train me. I started in January and in June he took me to my first competition in Bradenton, Florida,” she recalled.Dr Susan's photos show that she has devoted long hours to taking care of her body. But she also develops her mind and spirit. On any given day, she gets up at 3 am to read books. At 4:30 am she's out to walk three miles and run another three. This is followed by yoga and a swim at the beach while the sun rises. After writing her journal and working on her book between 8 and 10 am, she hits the gym for at least two hours. “I don't lose track of time,”she said.Dr Susan's war on ageism has rubbed off on her two daughters, both in their early thirties. “They both take care of their bodies and minds. If you give them a good foundation as a parent, you know that they will always come back to their roots. I tried to remind myself of that during their difficult teen years.”4.

She will set up a fitness foundation.B. She will soon return to retirement.C. She often thinks of her teenage years.D. She sets an example to her daughters.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 to night 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 ofmemory, 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.D14 days. That’s the time Chinese scientists took to identify the full genetic sequence of the novel coronavirus (新冠病毒) since its outbreak. It was shared with the WHO immediately, and has now become an important foundation for global researchers in the fight against the COVID-19. But first, let us turn the clock back 17 years, when it took months to identify the SARS virus. From months to 14 days, what changed? It turns out AI played an important part.The scientists first obtained bronchoalveolar lavage (BAL) fluid (支气管扩张灌洗液) samples from patients, isolated (分离) the DNA and RNA, then sequenced the genetic material by comparing them. AI’s advantage is its ability to recognize patterns among a flood of data.Let me put it in a simple way. Sequencing the coronavirus genome (基因组) is similarto looking for a needle in a haystack (干草堆)---looking for genotypes (基因型) with specific characteristics from a huge gene pool. That’s where search algorithm (算法), a branch of modern AI, comes in. Think of it as an efficient search engine, which can find the needle in the haystack. This search algorithm can shorten months-long genetic sequencing to weeks or even just a few days. Combined with macro-genomic sequencing and a virus library, this AI technology can also be used in tracking virus mutation (突变).AI doesn’t just support scientists. It can also help patients by improving the efficiency of diagnosis (诊断).Chinalaunched a Genomics Service, which can run multiple virus gene comparisons and produce a detailed report within 60 seconds. This algorithm hasbeen put into use inChinaand shared to the world for free.12. AI’s advantage is that it can ________.A. slow down the spread of coronavirusB. separate DNA from RNAC.identify specific genotypes rapidlyD. obtain samples from patients quickly13. The search algorithm helps shorten the time of genetic sequencing by __________.A. finding a needle in a haystackB. serving as a search engineC. combining with a virus libraryD. tracing virus mutation14. What do we know about the Genomics Service in the last paragraph?A. It has been widely used in the world.B. It is mainly based on blood test.C. It is for fast diagnosis of COVID-19.D. It is used to track COVID-19 patients.15. What’s the best title of the passage?A. 14 Days---ChinaMade it!B. AI Assists in COVID-19 FightC. Search Algorithm, Best ChoiceD. China’s Genomics Service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。

材料一先秦史传文学，从最早的《尚书》到《春秋》《国语》《左传》《战国策》，其“史传”的性质逐渐减弱，而“文学”的性质则逐渐加强。

《尚书》记言直录，不别方语雅言，亦不加裁剪；《春秋》记事简洁，如新闻标题一般；后世文学家对这两部著作推崇倍至，主要是崇其高古，很难说其有多少文学意味。

至《国语》《左传》，记言记事写人，尚裁剪，重技法，且开始出现与史无关而于文有益的“闲笔”，其叙述之高明，言语之醇美，较之《尚书》《春秋》，非止一箭之进。

到《战国策》，夸张失实之处俯拾皆是，很多记述都是出于文学的考虑，而难以史学的标准衡量，最突出的便是“床笫之私”“密室之谋”之类情景的记述。

发展到两汉时期，史传文学的巅峰之作《史记》出现，这两方面性质同时达到了最高水平，“”，言其史传之成就，“”，言其文学之成就。

This time, he recommends some emotionally powerful books.The Book of Delightsby Ross Gay(2019)Gay's collection of 102 short but emotional stories, begun in mid-2016 and written in the order of time over a year in America, focuses on the careful observation of ordinary delights in daily life. The writing is personal and grounded in thoughtful joy.100 Essays I Don't Have Time to Writeby Sarah Ruhl(2014)Seemingly a collection of essays on theater, Ruhl's book feels instead like the playwright's thoughts all of life.

Paige Lewis.3. Where is the text most likely from?A. A diary.B. A brochure.C. A website.D. A magazine.BThe first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.Because doctors make so many decisions that have serious consequences, thefalloutfrom second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we mayinvoluntarily overanalyze and come to the wrong conclusion.I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.4.

All of my hard work paid off. My mom had spent a lot on my attending a private high school, so I made sure to push myself: I volunteered, took part in various clubs, and graduated with honors. I was so excited to start a new part of my life.Soon enough, the big day came, but it wasn't like what I had thought. The first two weeks were the most difficult days of my entire life. Every night I would cry myself to sleep. I was missing my family, my home and everything in my hometown so much and I didn’t know how to deal with my broken heart.To distract myself, I threw myself into my studies. I also found a ton of jobs. In any free time, I started forcing myself to go to the gym. I wanted to keep every part of my day busy so I wouldn’t think about how lonely I felt.Soon after, I began to control my eating, considering it another solution to my homesickness. But soon there was something wrong with me.Finally, I went to see a doctor. When the doctor told me I had no choice but to take time away from school, I started to fear. How could I stop? School was what I was best at. “I’m not so bad,” I thought in my head. But the result was that I was taken to hospital again a month later and my mother camewoefully. I had to take a semester off from school, and go to the treatment center near my home.If there are girls who are suffering similarly, I hope you know that there is hope and that you should have a positive attitude towards life. Though you may feel alone, there are so many people who can understand your struggle. That’s why I want to share my story.8. Why did the author push herself during high school?A.

Dengue is a serious disease affecting people in around 120 countries. It can cause high fevers, headaches, and severe pain. It’s caused by a virus spread by bites from mosquitoes. Therefore, dengue is more common in warm areas. Every year, roughly 390 million people get dengue, and as many as 25,000 die from it.Now scientists seem to have found a way to protect humans from dengue by first protecting mosquitoes.Dengue fever is caused by a virus. Though it may seem strange to think of it this way, the mosquitoes that spread the dengue virus are also infected with it. But the virus doesn’t seem to hurt the mosquitoes.Wolbachia is a kind of bacteria commonly found in many insects. In some insects, Wolbachia can keep some viruses fromduplicatingthemselves, which is how viruses grow inside a body. Wolbachia isn’t naturally found in mosquitoes. But by infecting these mosquitoes with Wolbachia, scientists can keep the mosquitoes from catching the dengue virus. Even better, the young mosquitoes coming from the eggs of the infected mosquitoes also carry Wolbachia.Researchers working with the World Mosquito Program (WMP) ran a 27-month study in Yogyakarta, Indonesia. They split a 10-square-mile area up into 24 smaller areas. In half of the areas, the scientists did nothing. In the other half, they set out containers of eggs from mosquitoes that had Wolbachia. They did this every two weeks for just 4 to 6 months.Ten months later, 80% of the mosquitoes in the treated areas carried Wolbachia. The researchers report the number of dengue cases in the treated areas was reduced by 77% and that the number of people needing hospital care for dengue dropped by 86%.Because the results of the experiment were so good, the WHO has placed Wolbachia-infected mosquito eggs in all parts of Yogyakarta and surrounding areas. The WHO says that within a year, their efforts will protect 2.5 million people against dengue and that their efforts will be turned into a program that can be repeated worldwide.12. What kind of disease is dengue?A. It is likely to cause death.B. It causes no pain but fevers.C. It happens less often in hot areas.D. It hurts both people and mosquitoes.13. The underlined word “duplicating” in paragraph 3 most probably means “________”.A. worsening the harm ofB. expanding the size ofC. increasing forces ofD. making copies of14. What can be inferred about the method from the figures listed in paragraph 5?A. Its wide use.B. Its effectiveness.C. Its complexity.D.Its easy operation.15. What’s the WHO’s attitude towards the method?A. Ambiguous.B. Positive.C. Tolerant.D. Skeptical.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。

2019-2020学年西城实验学校高三英语上学期期中试卷及答案

2019-2020学年西城实验学校高三英语上学期期中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ASome young people win attention because of their good looks or their singing ability. A much smaller number gain fame because they have done something important and worthwhile with their abilities. Rishab Jain is among the latter. In 2018, 13-year-oldRishab developed a way to use AI technology to help pancreatic(胰腺的) cancer patients and won the3MYoung Scientist Challenge, a nationwide middle-school science competition, and its $25,000 prize.In the last stage of the contest, Rishab competed againstnine other finalists at the 3M Innovation Center(创新中心) in St.Paul,Minnesota. Leading up to the big meet, each finalist had partnered with a scientist to further develop their inventions.Rishab explains what led him to create his invention. First,a family friend died of cancer. Then Rishab learned about how deadly pancreatic cancer is, and that its low survival rate is due to how difficult it is to treat. "I'm also into programming, so I was learning about AI technology. I decided to try to solve a real-world problem using it."His winnings have been put in further research and in his nonprofit Samyak Science Society, which helps poor children enter the STEM (science, technology, engineering and math) education. Rishab is also raising awareness about pancreatic cancer. These efforts make him quite different from teenagers of his age. Considering becoming a biomedical engineer or a doctor一or both, he has also put some money aside to further his own learning. Almost certainly the doors of higher education will open wide to him before he even knocks.That's an outstanding outlook for one so young. Rashib is committed to helping very sick people in need. He is also providing teenagers of his age with a much-needed model of what kinds of things youth can achieve.1. What can we learn about the 3M Young Scientist Challenge in 2018?A. It was intended to solve medical problems.B. It was a nationwide AI competition for teenagers.C. It offered the finalists an opportunity to work with scientists.D. It allowed the finalists to learn AI technology in the 3M center.2. How did Rishab win the 3M Young Scientist Challenge?A.He showed excellent programming ability.B. He figured out the survival rate of pancreatic cancer.C. He introduced poor children to STEM education.D. He applied AI technology to treating pancreatic cancer.3. Which of the following best describes Rishab?A. Talented and caring.B. Independent and humorous.C. Responsible and patient.D. Polite and inspiring.BWhen I was a child, I attained high grades in my academic study. However, I was physically uncoordinated because I was running too slowly. But for future college application, sport was a must. So I took up fencing (击剑) because I thought it required more strategy than athletic ability.Then I joined the school’s fencing team. My movements were clumsy compared to the seniors. One afternoon after a whole lesson’s failure, tears of frustration welled up in my eyes. One of my teammates approached me, “Could you tell me where your blade (剑) hit me?” She asked. I pointed to her right shoulder. She nodded and patted my stomach, “That’s where I hit you.” She had begun to walk away when I blurted out, “Want to practice together? Again?”We practiced until we both felt more confident. But it wasn’t just the two of us. All these girls were entirely willing to share their knowledge with everyone, helping each other to grow.That afternoon, I watched a senior fencer execute a flawless attack admiringly. Something inside me suddenly bloomed. I realized later that it was love for both fencing and the fencing team.During the city championship, I was selected to fence. My opponent was the best fencer on her school’s team. “Ready, fence.” The match began. Suddenly, my opponent’s blade hit me. The score was 1-0.At the moment I could hear my teammates shouting, “Keep distance!” And the team captain’s voice was clear and commanding, “Parry, then disengage!”Fencing, unlike academics, wasn’t something I could succeed in by myself—even during an individual match, my teammates were still giving me advice. Unathletic as I was, I was proud to be an athlete and a teammate.I saw my blade tip bury itself into my opponent’s shoulder and the judge signaling that it was my point. I could taste the sweat on my lips, which were breaking out into a smile.4. Why did the author start to learn fencing?A. Because she needed to train her coordination.B. Because she thought it would be easier for her.C. Because she could not succeed in any other sport.D. Because she wanted to enter the school fencing team.5. How did the girls improve their fencing skills?A. By observing flawless attacks.B. By practicing on their own.C. By offering guidance to each other.D. By competing with other teams.6. What distinguishes fencing from academics according to the author?A. Strong determination.B. Hard work.C. Athletic strategy.D. Team support.7. How did the author feel when she got her point?A. Unbeatable and respectful.B. Sweaty and ashamed.C. Energetic and secure.D. Proud and thankful.CAn ancient tomb was recently discovered in southern Siberia in which there may be treasure, priceless objects, and the 3, 000-year-old remains of an ice mummy.Swiss scientist Gino Caspari with the University of Bern was looking carefully at the pictures of the area in the Russian Tuva Republic, when he came across what appeared to be a tomb. It is a tomb of the Scythians, an ancient group of Eurasians.This summer, together with researchers from the Russian Academy of Sciences and the Hermitage Museum, a dig at the site not only proved Caspari's idea, but told us the site is the largest and oldest of its kind ever discovered in what's increasingly known as the “Siberian Valley of the Kings.”While any discovery dating back to a period between the Iron Age and Bronze Age is exciting, it's the nature of this site that makes scientists want to begin carefully clearing away the layers of rock and earth. First, the tomb appears to have never been dug, because it is in a Siberian wetland faraway from the nearest place where people live. Second, and most important, is its possible resting place under a thick layer of permafrost.“There's permafrost in the area,” Caspari said. “There are really only a handful of permafrost tombs and very few that have not been damaged, where there have been ice mummies in good condition, and all the things in the tomb are untouched.”While not as large, other tombs discovered in the area have produced fantastical treasures and objects, including thousands of gold objects and other things about the past. By studying all these tombs, researchers hope to have a better understanding of the Scythian people.Caspari said his team is in a race against time to uncover the tomb and find out its secrets. “We now have to act fast,” he said, “because with the rising temperatures, the permafrost could melt and damage all the things in that tomb. And these are things that are over 3,000 years old, that look like new, like they were put there yesterday.”8. How did Caspari discover the tomb?A. By studying pictures.B. By visiting a Russian area.C. By talking with Russian researchers.D. By comparing other scientists,ideas.9. Why has the tomb remained untouched?A. It is covered by a lot of rocks.B. It is well kept by the Scythians.C. It is too small to draw attention.D. It is hidden in a wild cold place.10. Why do scientists want to uncover the tomb?A. To better protect the tomb.B. To save the treasures inside.C. To learn more about the Scythians.D. To have a good understanding of mummies.11. Why is Caspari's team racing against time to dig the tomb?A. The tomb is too old.B. It is getting hotter and hotter.C. Some treasures are being damaged.D. They want to save time for other tombs.DThe AI research arm of Alibaba created a machine learning model that received a higher score on the Stanford Question Answering Dataset than humans. The database consists of more than 100,000 questions to test reading comprehension.In early January this year the Alibaba AI software machine scored 82.44 on the test while humans scored 82.304. Besides, computers and AI have already defeated humans, for example in games such as chess. However, it seemed that language skills were superior in humans as machines find languages hard to master.A large number of call center employees, often in developing countries, may be out of work soon if the AI robots are cheaper and as effective as human labor. Soon when you phone a company for information the conversation will go like this: “ We are sorry but all our robots are busy right now. We value your call. Please stay on the line until a robot is free to serve you. There are just 12 callers ahead of you.” A robot will serve you some popular tunes while you wait.Si Luo, who is a chief scientist of natural language processing at Alibaba’s AI research group noted that questions such as “What causes rain?” can now be answered with a high degree of accuracy by robots. Si Luo said,“ We believe the foundational technology can be gradually applied to a lot of applications such as customer service, museum tutorials, and online responses to inquiries from patients, freeing human efforts in a new way.”Si Luo’s team is working closely with Ali Xiaomi, a mobile customer service chatbot. Ali Xiaomi can be customized to be used on Alibaba’s platforms such as Taobao and Tmall. The new AI robots could answer consumers’ questions as they did the Stanford questions. The robots would look for the answers from prepared information. However, there are limits to what the system will be able to do. If questions do not have clear-cut answers, or the questions asked are too unclear or ungrammatical, the robot may not be able to deal with them.12. What can we learn about the Alibaba AI software machine?A. It has been tested in some areas.B. It has become popular since January.C. It has offered a special learning style.D. It has made people interested in reading.13. What does the example in paragraph 3 show about the AI robots?A. They should have better language skills.B. They may replace humans in some fields.C. They need to be customized to serve customers.D. They will be widely used in developing countries.14. How does Si Luo feel about the foundational technology?A. Doubtful.B. Worried.C. Curious.D. Confident.15. What can we infer from the lastparagraph about Ali Xiaomi?A. It needs to improve in some ways.B. It is connected with another system.C. It is a platform to show good service.D. It can answer any questions accordingly.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。
