2021届西安市铁一中学高三英语模拟试卷及答案
2021届西安市铁一中学高三英语模拟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AIf you are sending a text message watching TV or listening to the radio, you may stop and give this your full attention. Multitasking shrinks (使.....萎缩)the brain? research suggests.A study found that men and womenwho frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, " Using mobile phones, laptops and other media devicessimultaneouslycould be changing the structure of our brains."Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multitasking with a shortened attention span, depression , anxiety and lower grades at school.The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking e-mail, or speaking on the phone while watching TV and surfing the Internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingu-late cortex (ACC)(前扣带皮层).Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.Other studies have shown that training—such as learning to play magic tricks or taxi drivers' learning the map of London―can increase grey matter densities (密度)in certain parts.Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99，and found 20%had problems with memory. Researchers were shocked greatly by the 14 % of 18 to 39-year-old people who also worried about their memories.Multitasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.1. The underlined word " simultaneously" in Paragraph 2 means "________，"A. on one's ownB. at no timeC. at the same timeD. by accident2. All of the following are possible effects of multitasking EXCEPT________ .A. saving timeB. a shortened attention spanC. lower grades at schoolD. depression and anxiety3. Which ofthe following can be the best title of this passage?A. Media multitasking is becoming more popularB. Multitasking shrinks the brainC. Multitasking may shorten attention spanD. People are worried about their memories.BScientists have long sought to prevent sharp memories from dulling with age, but the problem remains unsettled. Now research published in Scientific Reports suggests virtual reality might help older people recall facts and events based on specific details.The study involved 42 healthy older adults from the San Francisco Bay Area. Half spent a dozen hours over four weeks playing a virtual-reality game called Labyrinth; they wore headsets and walked in place, walking virtual neighborhoods while completing small tasks. The other half, in the control group, used electronic tablets to play games that did not require recalling details. After 15 sessions (期), the latter performed roughly the same as before on a long-term memory test. But the Labyrinth players gain an improvement in memory through the VR game. A scientist Peter Wais of the University of California said the improvements brought them up to the level of another group of younger adults taking the same memory tests.Meredith Thompson, an education researcher, studies learning through VR games but was not involved in the new study. It would be great to actually follow people over time and see what this type of game does for long-term memory. She says, adding VR can provide greater involvement than other games. Wais's team is now investigating how long the observed effects last and which elements of the training have the most impact.A cognitive (认知)psychologist, Daniel Simons, who was also not involved in the study, notes experiments with other games that claim to train the brain have often failed to evaluate this. And it remains unclear how test performance in a laboratorysetting might translate to real-world situations. The outcome, Simons notes, “needs to be repeated, ideally with a much larger group, before it’s treated as a strong finding.”For now, Wais says, the team hopes its studies with similar-sized groups will help draw funding to test the game in a larger pool of participants.4. What is the passage mainly about?A. People's memory gradually fails as they age.B. People of different ages should play VR games.C. Virtual reality changes people's memory.D. Virtual reality improves older adults' memory.5. What is Meredith Thompson's attitude toward the research?A. satisfied.B. enthusiastic.C. cautious.D. concerned.6. According to the scientists, the research needs to be improved due to ________.A. the lack of financial support.B. the limited pool of participants.C. the unsatisfying test performance.D. the impractical application in real world.7. Where may the passage come from?A. A novel.B. A review.C. A magazine.D. A guidebook.CNASA has flown an aircraft on another planet for the first time. On Monday, April 19, Ingenuity, a 1. 8-kilogram drone (无人机) helicopter, took off from the surface of Mars, flew up about threemeters, then hovered for 40 seconds and took photos above with one of its two cameras. The historic moment was livestreamed on YouTube. “We can now say that human beings have flown a drone helicopter on another planet,” said MiMi Aung, the Ingenuity Mars Helicopter project manager at NASA's Jet Propulsion Laboratory, at a press conference. “We, together, flew at Mars, and we, together, now have our Wright brothers moment,” she added, referring to the first powered airplane flight on Earth in 1903.The details: The flight was a significant technical challenge, thanks to Mars' s bone-chilling temperatures (nights can drop down to -130 °F / -90 °C) and its incredibly thin atmosphere — just 1% the density of Earth' s. That meant Ingenuity had to be light, with rotor blades (螺旋桨) that were bigger and faster than would be needed to achieve liftoff on Earth (although the gravity on Mars, which is only about one-third of Earth's, worked in its favor). The flight had originally been scheduled to take place on April 11 but was delayed by software issues.Why it's significant: Beyond being a significantmilestonefor Mars exploration, the flight will also pave the way for engineers to think about new ways to explore other planets. Future drone helicopters could help astronauts by scoping out locations, exploring inaccessible areas, and capturing images. Ingenuity will also help inform the design of Dragonfly, a car-size drone that NASA is planning to send to Saturn's moon Titan in 2027.What's next: In the next few weeks, Ingenuity will conduct four more flights, each lasting up to 90 seconds. Each one is designed to further push the limits of Ingenuity's capabilities. Ingenuity is only designed to last for 30 Martian days, and is expected to stop functioning aroundMay 4. Its final resting place will be in the Jezero Crater as NASA moves on to the main focus of its mission: Getting the Perseverance rover (毅力号火星探测器) to study Mars for evidence of life.8. Why does MiMi Aung mention Wright brothers?A. To honor the historic contribution of Wright brothers.B. To make a comparison between Wright brothers and herself.C. To highlight the importance of Ingenuity's Martian exploration.D. To remind the public of the first powered airplane flight on Earth.9. What caused challenges for Ingenuity designers?A. The delay of software tests.B. The force of gravity on Mars.C. Mars's temperatures and atmosphere.D. Technical difficulty in liftoff on Earth.10. What does the underlined word “milestone” in Paragraph 3 probably mean?A. A great victory.B. A difficult task.C. A roadside stone.D. A historic event.11. Which of the following can be a suitable title for the text?A. Mars Drone Helicopter Makes Historic First FlightB. Modern Wright Brothers Moment: Mars ExplorationC. First Drone Helicopter Spots Evidence of Life on MarsD. Ingenuity: Mars Drone Flies to Take Incredible PicturesDI was at the hardware store the other day and overheard a woman tell Ed., the manager, that fall was her favorite time of year. Ed., because he liked to keep his customers happy, agreed that fall was a wonderful season, but I could tell he was lying.I was going through my mind recently, trying to find sweet memories of fall. I failed. I met my wife in the summer and married her two summers later. My sons were born in the winter and summer, my granddaughter in the winter. I’ve been fried twice in my life, both in fall. One October, a truck carrying tofu ran a red light and hit me,destroying my favorite car, combining the three things I most hate - trucks, tofu and October.I'm not saying fall is without its attractions. The leavesare beautiful. But fall's vacillation (立场摇摆)is troubling, its effort (努力)to please everyone, its continuous search for the middle ground to be all things to all people. Say what you will about summer and winter, at least they have the courage to keep their opinions strong, even if they kill us with extreme heat or cold.I recently read a story of a man coming out of a three-month coma (昏迷). It started in early fall and ended just as winter came. I hope if I were ever in a coma I would be just as lucky as the man.Upon my awakening, one of my families who stood around my bed would ask. "Don't you remember anything from the past three months?""Not the first thing," I would happily report.If I ever have enough money. I'm going to buy a second home inAustralia, so that when fall starts here, I can move there for three months, just when spring is starting.12. What did Ed think of the customers words according to the author?A. Ed understood them and supported the customer completely.B. Ed might hold a different opinion on the topic.C. Ed believed the customer wasn't telling the truth.D. Ed thought they stood for most peoples' opinion.13. What can we infer from Paragraph 2?A.The author has a big and loving family.B. The author is having a hard time at work.C. It is important to follow the rules of the road.D. Nothing good has happened to the author in fall.14. Why does the author say the man in Paragraph 4 was lucky?A. Because he slept fall away.B. Because he ho sweet memories of fall.C. Because hedreamed of fill many times.D. Because he was met by his family when waking up.15. Which of the following does the author most want to do?A. Drivetracks.B. Eat tofu dishes.C. Watch leaves falling in fall.D. Move toAustraliain October.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届陕西省西安中学高三英语一模试卷及答案解析
2021届陕西省西安中学高三英语一模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AOne day when I was 5, my mother blamed 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. When angrily opening 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 blamed 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. However, my parents never said a word. They left the corner of the screen door pushed out, creating an opening, in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. 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 (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. Iwould wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered 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 perhapscould not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.1. When the author damaged the door, his parents _______.A. gave him a spankingB. left the door unrepairedC. told him how expensive it wasD. blamed him for what he had done2. The experience may cause the author _______.A. not to go against his parents’ willB. to have a better control of himselfC. not to make mistakes in the futureD. to hide his anger away from others3. What is the main idea of this text?A. Parents is the best way to solve problems.B. Parents are the best teachers of their children.C. Adults should ignore their children’s bad behavior.D. Silent punishment may have a better effect on educating people.BThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reduces the need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.4. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.5. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems6. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater7. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.CAlthough computer technology is often necessary today, using a pen or pencil activates more areas of your brain than a keyboard does. You can potentially remember more by handwriting, according to a new study.The potential benefits of handwriting for memory have been debated for some time. The new study set out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?In all,24 participants took part. Researchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hair net fitted with 256 sensors. Those sensors recorded the participants' brainwaves. The electrodes noted which parts of the brain turned on during each task. And they showed that writing turned on memory areas in the brain while typing didn't.Audrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is because writing involves complex movements that activate more areas of the brain. The increased brain activity gives the brain more ‘hooks’ to hang your memories on,” she explains. Van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings,” she adds.This study does not recommend banning digital devices. In fact, its authors point out, computers and other devices with keyboards have become necessary in modern society. Keyboarding can especially benefit those with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.8. Why were participants asked to wear caps in the study?A. To record their brainwavesB. To inform them of their tasksC. To allow them to focus on writingD. To protect their heads like hair nets9. What does Audrey van der Meer try to explain?A. Why handwriting is more complex than typingB. Why the brain works when it comes to learningC. Why handwriting helps remember informationD. Why key words are helpful to visual notetaking10. What is the study's authors' view on typing?A. It relieves people's handsB. It remains vital and helpfulC. It is not worth recommendingD. It is more challenging than writing11. Which of the following can be a suitable title for the text?A. How Can You Remember New Information?B. Handwriting Benefits Health in the LongRunC. Should Typing Take the Place of Handwriting?D. Handwriting Is Better for Memory Than TypingDWhen rescuers were called to rescue a “little owl”, they did not expect to find one that was too fat to fly. A concerned citizen first spotted the poor bird lying helplessly. Even Rufus Samkin, whose team then took the team in on Jan.3, believed the bird to be injured. There were no wounds to be found, however, causing experts to believe the female owl was simply too wet to fly.But it was only after a thorough drying-off and complete checkup that they noted the real issue. The rescuers weighed the owl and concluded that she was “simply extremely obese” and couldn’t take off. This additional weight left her unable to fly, though experts began to wonder how she got so fat in the first place. Because it’s rather unusual for wild birds to reach such a state, they decided to keep her a few weeks and monitor her.In the end, the rescuers assessed that it was simply a case of “natural obesity”. December 2019 was quite warm, which meant that there were many insects for the bird to feast upon. Indeed, the owl was discovered in a field that was “filled with field mice” due to the usual climate. “It’s been very mild here, and the owl is able to find foods easily,” Samkin explained. With the sudden food, “she ly ate much and got very fat. She had a lovely time, but went too far.”The researchers consequently put the owl on a “strict diet” so she could shrink to a more “natural weight”. She was even put on a bit of exercise and encouraged to fly around. In the end, the bird was sent flying gracefullyoff into the British countryside at a much healthier and happier weight. Hopefully, this owl won’t come upon another feast of field mice—unless she wants another few weeks at the fat camp.12. What did people think happened to the owl at first?A. She was hurt.B. She was trapped.C. She was hungry.D. She was wet.13. Why was the bird unable to fly?A. She needed a thorough checkup.B. She should be given a drying-off.C. She was completed overweight.D. She was simply extremely strong.14. What made the owl have enough foods?A. The especially warm weather.B. The reducing number of insects.C. The rich fields growing crops.D. The lovely time the bird enjoyed.15. How did the owl loseits weight?A. Going on a diet and exercising.B. Flying in the British countryside.C. Visiting that fat camp again.D. Enjoying her wonderful feast freely.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’d watch as he put his personal items away: his watch, wallet, comb and car keys would always occupy the same spot on the table every time.Dad’s comb was bought when he married Mum. Every evening, he would smile, hand me the comb and say: “Be a good girl and help Daddy clean it, OK?” I was more than happy to do it. This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change.

My Memory with My Dad.D. I Love My Family Members.CA new study finds almost one third of the world’s population is overweight. Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.8. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people9. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh10. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit11. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.DThe health benefits of staying active are already well-known. It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above inEnglandandScotland, who were surveyed about their health, lifestyle and exercise patterns.After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besidesthe named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.12. How is the study conducted?A. By doing comparative experiments.B. By analyzing previous data.C. By evaluating survey information.D. By tracking participants for a long time.13. What does the underlined part “the named sports” refer to?A. Ball sports.B. Racket sports.C. Individual sports.D. Traditional sports.14. What can we infer from paragraph 5?A. Few people will play football.B. Tennis will become more popular.C. The result of this study is wrong.D. The study needs to be further improved.15. What does the author advise people to do?A. Stick to any sport that you like.B. Play badminton and tennis only.C. Stop running and playing football.D. Do any sport according to guidelines.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。

What do we know about TikTok?A. It is an India-based app.B. It has most users inAmerica.C. It is used for growing business.D. It has doubled its download than in 2019.2. Which app is the best to turn to for online education?A. TikTok.B. Zoom.C. WhatsApp.D. Facebook.3. What function does Facebook probably serve?A. Communication.B. Training.C. Teaching.D. PaymentBIt’s 13:30 and 28-year-old Marten Pella 's smart phone starts pinging, a signal that it’s time for us to stop working around his living room table and instead start our workout routine together. A cartoon character wearing bright red shorts on video begins instructing us to do star-jumps and sit-ups around his apartment.Pella, a research assistant at Stockholm University, is part of the Hoffice movement, which invites workers-freelancers（自由职业者）or full-time employees who can do their jobs remotely—to work at each other’s homes to increase productivity and enjoy an active social life.Those attending Hoffice events advertised on Facebook are typically asked to work silently in 45-minute blocks, before taking short breaks together to exercise, or simply chatting over a coffee. In addition, each participant shares daily objectives with the rest of the group upon arrival, and is invited to report back on whether or not they have achieved them at the end of the day.“Often when I am alone, I can work focused for a couple of hours but then I’m easily distracted（分心）.The help of others makes me so much more disciplined.” says Pella, who attends Hoffice events as both a guest and a host. Lunches mean networking and connecting with new contacts. “People are coming from really different areas and have different professions so there can be really interesting discussions,” he says.The Hoffice movement has grown quickly since it was founded in 2014 by Swedish psychologist Christofer Franzen, now 37. He had been giving lectures on the benefits of collective（集体的）intelligence, but realised he was spending most of his own time working alone at his kitchen table. “I wanted to test more structured home co-working with friends in similar situations,” he says.Franzen says that holding events in houses and apartments creates a unique atmosphere, because there’s a sense of community and desire to contribute. He’s looking for ways to expand the social value of Hoffice, by matching up members with relevant skills to share and even encouraging jobseekers to join its gatherings.4. Where is Pella when his smart phone starts pinging?A. In his own home.B. In his office.C. In another person’s home.D. At Stockholm University.5. What do people attending Hoffice events do first when they meet?A. Watch an exercise video.B. Work silently for 45 minutes.C. Tell each other their daily plans.D. Report what they have achieved.6. What does Franzen really mean by saying “friends in similar situations”?A. They usually work alone.B. They often give lectures.C. They study collective intelligence.D. They have to work at a kitchen table.7. What is the best title for the text?A. Sharing Comfortable WorkplacesB. A New Way to Make New FriendsC. Benefits of Collective IntelligenceD. Working from Others’ HomesCMost people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world’s population is left-handed.Why are there more right-handed people than left-handed ones? Scientists now know that a person’s two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person’s hands and eyes work together, controls the left hand. The left-side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn’t happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene(基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.Though right-handedness is more common than left-handedness, people no longer think left-handed peopleare strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don’t have to.8. After studying works of art made at different times in history, the scientists found _______.A. the art began from 1,500B.C.B. the works of art ended in the 1950sC. most people shown in the works of art are right-handedD. most people shown in the works of art are left-handed9. What is the left hand for most people used to do?A. It’s used to find or hold things.B. It’s used to work with things.C. It’s used to make a person’s eyes work together.D. It’s the centre for thinking and doing problems.10. According to the passage, which of the following is NOT true?A. No one really knows what makes a person become right-handed.B. Left-handedness is cleverer than right-handedness.C. Today children are not made to use their right hands only.D. Scientists think there must be some reason why people become left-handed.11. The best title for this passage is _______.A. Scientists’ New InventionsB. Left-handed PeopleC. Which HandD. Different Brains, Different HandsDThe outbreak of the novel corona virus pneumonia (NCP) has disrupted the lives and work of nearly every Chinese person. However, a new trend has been on the rise: many have turned themselves into livestreaming users orfollowers.According to Questmobile, a professional big data intelligence services provider in China, the audience for Douyin, Kuaishou and other livestreaming platforms surged to 574 million during the Spring Festival holiday, up 35 percent from 2019.Confined at home, away from their friends and loved ones, people turn to livestreaming to reach out to the world. For them livestreaming can help them share their lives and interest with a global audience, which will give them the sense of being “in the moment”. Even as viewers, they can also engage immediately with livestreamersby commenting and making suggestions.“When I comment on the livestreaming videos, I’m not simply an audience member, but also an active part of the program. That gives me a sense of engagement,” an Internet user named Wang Hao told People’s Daily.Livestreaming is not only for fun, but also a new tool for many businesses. Affected by the pandemic, many businesses had to stop their sales in physical stores. To meet their business goals and survive during these trying times, many chose to livestream to revive their businesses.Joyoung, a leading maker of small kitchen appliances, is a good example. The company not only added a number of broadcasts each day to advertise their products, but also shared the menus that were beneficial to health. “The responses to our livestreaming shows have been well beyond expectations,” Kang Li, who oversees the company’s livestreaming unit, told China daily. “It’s a natural opportunity to truly bond with our followers.”Like it or not, livestreaming is likely to go mainstream in China for both entertainment and business.12. What is the purpose of writing the second paragraph?A. To introduce some popular livestreaming platforms in China.B. To report data on the development of livestreaming in 2019.C. To show that Chinese people spend too much time on livestreaming apps.D. To prove that livestreaming are becoming increasingly popular in China.13. What does Wang Hao think of commenting on livestreaming?A. It is boring to make comments.B. It is the only way to share viewers’ lives.C. It makes people feel involved in the stream.D. It helps livestreamers improve themselves.14. What do paragraphs 5&6 mainly talk about?A. Livestreaming replaced physical stores in many areas.B. Many businesses turned to livestreaming platform for marketing.C. Livestreaming platforms faced challenges during the pandemic.D. Livestreaming platforms made changes to their services.15. How does the author feel about thefuture of livestreaming？A. Positive.B. Uncertain.C. Disappointed.D. Confused.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。

On the Internet.BFrom skateboarding to Fleetwood Mac, TikTok users got creative in a pandemic (流行病) year with new songs, dances and shows in 60 seconds or less.The social mediavideo app on Wednesday shared its list of top 100 videos, creators and trends in America during 2020. “These videos brought joy and inspiration to millions of Americans in the rough year,” said Kudzi Chikumbu, director of creator community at TikTok.The platform has been widely associated with Generation Z (people born after 1996), millennials (people born in the 1980s or 1990s) and influencers who have started careers based on the shared videos.The Weeknd'sBlinding Lightsand Jason Derulo's Savage Loveinspired TikTok dance challenges that made them among the top songs used on the app.For some TikTok creators, the pandemic itself became inspiration to create a connection with other users. Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed it more into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikTok trulytranscendsgenerations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”4.

Makes use of.B. Goes beyond.C. Calls on.D. Takes charge of.CYour house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less selfconscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.Mind the color1 s. Research suggests warm color1 s fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm color1 s like yellow make food appear more appetizing, while cold color1 s make us feel less hungry. So when it’s time to repaint, go blue.Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makesyou less likely to rush through a meal.Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12inch plate instead of a 10inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.8. The text is especially helpful for those who care about ____________.A. their home comfortsB. their body shapeC. house buyingD.healthy diets9. A home environment in blue can help people ______________.A. digest food betterB. reduce food intakeC. burn more caloriesD. regain their appetites10. What are people advised to do at mealtimes?A. Eat quickly.B. Play fast music.C. Use smaller spoons.D. Turn down the lights.11. What can be a suitable title for the text?A. Is Your House Making You Fat?B. Waysof Serving DinnerC. Effects of SelfConsciousnessD. Is Your Home Environment Relaxing?DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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。

With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.The firm's End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 March aboard a Russian Soyuz rocket. It consists of two spacecraft: a smal “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser todock withit.The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at AstroscaleUK.“This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth's atmosphere.If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.4. Which of the following can replace the underlined word "dock with" in Paragraph 2?A. Deal with.B. Keep up with.C. Join together.D. Crash.5. Why many countries now require firms to have a way to bring back their satellites?A. Because of the growing space waste problem.B. Because the frequency of space launches are dramatically increasing.C. Because they can earn large profits from it.D. Because Astroscale has found a new method of capturing the space garbage.6. What will Astroscale do to solve the space junk problem?A. An astronaut controls a robotic arm on the International Space to capture the “client” satellite.B. Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite.C. Finding the "client "satellite and attaching to it with a magnetic plate automatically.D. Tumbling to match the motion of “client satellite the drag three or four satellites out of its orbit into atmosphere.7. What can we infer from the passage?A. People will bum the space junk up in Earth's atmosphere in the future.B. Japan andRussiawill conduct space debris cleanup experiment together.C. These kinds of demonstrations have never been done before.D. The demonstration mission will be divided into three phases.CGetting rid of dirt, in the opinion of most people, is a good thing However, there is nothing fixed about attitudes to dirt.In the early 16th century, people thought that dirt on the skin was a means to block outdisease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king ofEnglandin 1546. Thus began a long time when the rich and the poor inEuropelived with dirt in a friendly way. Henry IV, king ofFrance, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.Though the belief in the merit(优点) of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.8. The kings ofFranceandEnglandin the 16th century closed bath houses because .A. they lived healthily in a dirty environmentB. they thought bath houses were too dirty to stay inC. they considered bathing as cause of skin diseaseD. They believed disease could be spread in public baths9. Which of the following best describes Henry IV’s attitude to bathing?A. CuriousB. AfraidC. ApprovingD. Uninterested10. How does the passage mainly develop?A. By following the order of time.B. By making comparison.C. By providing examplesD. By following the order of importance.111. What is the author’s purpose in writing the passages?A. To call attention to the danger of dirt.B. To introduce the history of dirt.C. To present the change of views on dirt.D. To stress the role of dirt.DJoshua Nelson, 18, fromMissouri, is graduating fromSt. CharlesWestHigh Schoolthis week and will be attendingSoutheastMissouriStatein the fall. He had saved upmoney to pay for his tuition, but when he received the college's President's Scholarship, he decided to take his savings and donate it to other students in need.“It comes from my family education and faith," Nelson said. "I've always lived by strong principles as far as being a cheerful giver andhaving an open handwhen it comes to giving back so I feel like that really motivated me.”SEMO's President's Scholarship is the school’s most celebrated, and is only awarded to five top students annually. Nelsonsaid he sat down and outlined how a scholarship could work to help future students who need financial assistance for college. Originally the plan was to give away $ 1,000 the one time, but then he met up with his counselor (顾问), Yolanda Curry, to work outa game plan.“I wasn't expecting it at all!” Curry said. "He told me he had a great idea and wanted to share it with me. I could tell he was really excited.Nelson, in association with his high school, set up the Joshua Nelson Leaders In Action Scholarship fund. Each year, $1,000 will be awarded to a senior. The money will come from donations, of which there have been $16,000 so far — for a total of $17,435 at last count, according to the school.

Dear Mary，
How are you getting along these days? Knowing that the produce on your farm is hard to sell during the COVID-19 epidemic，I really feel as worried as you. So，I'm writing to share some successful Chinese experience to help you. Chinese farmers came across the similar problem not long ago，but they came up with a creative solution:promoting goods sales through livestreaming. What you need are a computer or a cellphone with access to the Internet and a live stream platform or application for broadcasting. By taking advantage of social influencer marketing，the sellers can introduce the goods more efficiently and the buyers can watch the products visually in real time，thus，making the online trade more convenient.To ensure the quality of live streaming，make sure the equipment and the Internet are of good quality and the surroundings are quiet and free of disturbance.

The Memorial of the Site of the First National Congress of the CPC.BCuckoos don’t bother building their own nests—they just lay eggs that perfectly imitate those of other birds and take over their nests. But other birds are wishing up, evolving some seriously impressive tricks to spot the cuckoo eggs.Cuckoos are often know asparasites, meaning that they hide their eggs in the nest of other species. To avoid detection, the cuckoos have evolved so that eggs seem reproduction of those of their preferred targets. If the host bird doesn’t notice the strange egg in its nest, the little cuckoo will actually take the entire nest for itself after it comes out, taking the other eggs on its back and dropping them out of the nest.To avoid this unpleasant fate for their young, the other birds have evolved a few smart ways to spot the fakes, which we’re only now beginning to fully understand. One of the most amazing finds is that birds have an extra colour-sensitive cell in their eyes, which makes them far more sensitive to ultraviolet wavelengths and allows them to see a far greater range of colours than humans can. This allows cautious birds to detect a fake egg which might be exactly the same to our eyes.Fascinatingly, we’re actually able to observe different bird species at very different points in their evolutionary war with the cuckoos. For instance, some cuckoos lay their eggs in the nests of the redstarts. Theblue eggs these cuckoos lay are practically alike to those of the redstarts, and yet they are still sometimes rejected. Compare that with cuckoos who target dunnocks. While those birds lay perfectly blue eggs, their cuckoo invaders just lay white eggs with brown irregular shaped spots. And yet dunnocks barely ever seem to notice the obvious trick.Biologists suspect these more easily fooled species like the dunnocks are on the same evolutionary path as the redstarts, but they have a long way to go until they evolve the same levels of suspicion. What’s remarkable is that the dunnocks fakes are so bad and the redstart ones so good, and yet cuckoos are still more successful with the former than the latter.It speaks to just how thoroughly a species’ behavior can be changed by the pressures of natural selection, or it might just be a bit of strategic cooperation on the part of the dunnocks. Biologists have suggested that these birds are willing to tolerate a parasite every so often because they don’t want to risk accidentally getting rid of one of their own eggs.4. This passage can be most likely found in a ________.A. science surveyB. nature magazineC. zoo advertisementD. travel journal5. What does the underlined word “parasite” in paragraph 2 most probably refer to?A. Animals that work together to raise young.B Small harmful animals such as worms or mice.C. Animals that can adapt to changing environments.D. Animals which live on or inside other host animals.6. Which of the following is TRUE about the dunnock according to the passage?A. It is colour-blind and therefore cannot identify foreign eggs in the nest.B. It can easily remove cuckoo eggs from the nest because fakes are so bad.C. It is a host bird that is more likely to raise a cuckoo chick than the redstart.D. It is unable to evolve and hence accepts cuckoo eggs that appear in the nest.7. Which of the following can be inferred from the passage?A. Dunnocks may eventually learn to recognise foreign eggs.B. Redstarts seem to be less suspicious compared to dunnocks.C. Cuckoo birds are good at taking responsibility for their own young.D. It is very easy for cuckoos to imitate the colouring of the dunnock’s egg.There are similarities and differences between high school life and college life.For one thing, there are several similarities between high school life and collegelife. First, the most important task in high school and college is both studying. Studying is the most important as a student. Second, we need a goal to fight for in both high school life and college life. To lead a meaningful life, we have to set up a goal to achieve.For another, there are also some differences between high school life and college life. First, our studying is also the biggest difference. In high school, we are required to follow our teachers' steps and finish theirassignmentsevery day. While in college, there are no teachers giving such detailed requirements to us and we can choose study or not according to our own willing. What and how to study totally depends on us. Therefore, the ability of self-control is very important in college life. Second, the flexibility (灵活性) of time is another difference. In high school, we have no much leisure except for our time of study. However, in college, we have much controlled by ourselves except the time of classes. And we have more time to do what we like. Finally, college lifeis much more various and richer. Besides study, we can attend many other activities, which make our college life more wonderful.In brief, there are both similarities and differences between high school life and college life. However, no matter we are in which period, we need to make full use of every day so that we will never feel regretful.8. Why do students need a goal to fight in high school and college?A. To enter a good college.B. To avoid living a meaningless life.C. To develop the ability of control.D. To meet their parents’ satisfaction.9. What does the underlined word “assignments” in paragraph 3 probably mean?A. Projects.B. Tasks.C. Goals.D. Dreams.10. Which is the correct structure of the passage?A. ①-②③-④B. ①②-③-④C. ①-②③④D.①②-③④11. Which of the following can be the best title for the text?A. College LifeB. High School LifeC. High School and CollegeD. High School Life and College LifeAfter finishing his dinner, Lin Xu opened a WeChat mini-program called "Clear Plate" on his phone and took picture of the empty plates. He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence.“Users of the app can use their credit to buy gifts, such as books and cellphones to purchase charity meals donated to children in poor rural areas,” Lin said.A nationwide "Clear Your Plate" campaign is gaining steam online. Efforts to stop food waste and promote thrift are also being made by restaurants that have been urged to create an environment in which consumers are reminded not to waste food. They are also encouraged to offer different portion sizes so that customers can have more choices.The “Clear Plate” mini-program has become popular among young Chinese and currently has nearly 1 million users.Liu Jichen, founder of the startup that developed the app, said that the idea popped up at a dinner in 2017, when Liu found that a restaurant would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected.“Such an idea can be realized online,” Liu said. He formed a team to work on the project.Yet it was quite challenge for the AI system to identify whether the uploaded photos showed empty plates.To make the AI system smarter, Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100, 000 samples in canteens and restaurants across the country and used the data to train neural network. Dozens of enterprises, institutions and restaurants have contacted the startup to cooperate on the project.Through the visualized mini-program, people can clearly see the good results of saving food, which will effectively reduce waste, he noted. "We hope our efforts can start a new trend among the younger generation, encouraging them to carry out the virtue of cherishing food and developing the habit of thrift, " Liu said12. What is the main function of the APP "Clear Plate?A. Awarding credit points.B. Giving charity meals.C. Showing the empty plates.D. Encouraging saving food.13. How is the "Clear Your Plate" campaign carried out?A. Customers wasting food are punished.B. People join in it on mini-program.C. Restaurants limit customers' choices.D. People are encouraged to buy gifts.14. What was the most difficult when the app was created?A. Getting other people to cooperate with the team.B. Collecting samples in canteens and restaurants.C. Ensuring the app to recognize empty plates.D. Finding people to fund the app.15. What is the purpose of the writing?A. To introduce an app.B. To promote saving food.C. To praise a startup founder.D. To raise fund for poor children.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。

He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theory and because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.4. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters5. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics6. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems7. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science textCIn life，once on a path，we tend to follow it，for better or worse.What's sad is that even if it's the latter，we often accept it anyway because we are so used to the way things are that wed don't even recognize that they could be different This is a phenomenon psychologist call functional fixedness.This classic experiment will give you an idea of howitworks and a sense of whether you may have fallen into the same trap: People are given a box of tacks (大头钉) and some matches and asked to find a way to attach a candle to a wall so that it burns properly.Typically, the subjects try tacking the candle to the wall or lighting it to fix it with melted wax. The psychologists had, of course, arranged it so that neither of these obvious approaches would work. The tacks are too short, and the paraffin (石蜡) doesn't stick to the wall. So how can you complete the task? The successful technique is to use the tack box as a candle-holder. You empty it, tack it to the wall. and stand the candle inside it. To think of that, you have to look beyond the box's usual role as a receptacle just for tacks and re-imagine it serving an entirely new purpose. That is difficult because we all suffer to one degree or another from functional fixedness.The inability to think in new ways affects people in every corner of society. The political theorist Hannah Arendt coined the phrase“frozen thoughts”to describe deeply held ideas that we no longer question but should. InArendt's eyes, the self- content reliance on such accepted “truths”also made people blind to ideas that didn't fit their worldview, even when there was plenty of evidence for them.Frozen thinking has nothing to do with intelligence, she said,“It can be found in highly intelligent people.”8. What does the underlined word“it”in paragraph 2 refer to?A. The experiment.B. Functional fixedness.C. The path.D. The thinking.9. Which way is hard to think of to complete the task?A. Tacking the candle to the wall.B. Fixing the candle with melted wax.C. Using the tack box as a candle-holder.D. Lighting the candle tostand it.10. Which of the following statements will Hannah Arendt agree with?A. People should question.B. We should be used to the way things are.C. People shouldn't accept the idea that doesn't fit their worldview.D. The smarter people are，the more open to the new things they are.11. What's the passage mainly about?A. An interesting experimentB. A psychological phenomenon.C. A theory to be proved.D. The opinion of Hannah Arendt.DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nationsfrom unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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届西安高级中学高三英语一模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AThe Origins of Famous BrandsOur lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders names, some of the companies we trust every day actually have fascinating and surprising back stories.StarbucksIt seems fitting that the most famous coffee brand in the world would take its name from one of the world’s greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville’sMoby Dick. The founders’ original idea was to name the company after the Captain Ahab’s ship, but they eventually decided that Pequot wasn’t a great name for coffee, so they chose Ahab’s first mate, Starbucks, as the name instead.GoogleGoogle was originally called Backrub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word “googol”. When a friend tried to register the new domain (域) name, he misspelled “googol” as “google”.NikeOriginally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is alsothe name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.The right name is essential to a company’s success, and a great origin story is just as important as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.1. What is the name of the Captain Ahab’s ship?A. Moby Dick.B. Starbucks.C. Pequot.D. Herman Melville.2. Why did the founders of the Google want to change its name?A. They mistook their name.B. They wanted new customers.C. The company’s original name was too long.D. The company’s search technology was improving rapidly.3. Where does the importance of the origin story of one company lie in?A. It can change the company’s image.B. It can add myth to the company.C. It explains the development of the company to customers.D. It makes customers imagine and purchase its goods.BJack was 11 months old in the spring of 2015 when his parents, Erika and Christopher, recognized his development was not progressing as it should. The feeling was familiar to the couple. Just a few months earlier, Jack’s brother Chase, who is 16 months older, had been diagnosed with autism(自闭症) after he did not reach motion and language standards as expected.Jack’s behaviors were similarly delayed, and his parents moved quickly to seek help. Today, Jack is 5 — he celebrated his birthday on May 13 — and he can speak in full sentences and read. After two years at a preschool that specializes in services for children with developmental disabilities, he will start kindergarten in theSmithtownschool district in September. “Our family’s experience is a good example of the power and effectiveness of early intervention. The services our boys have received made all the difference,” the parents said.According to scientists, autism can be detected at 18 months or younger, and by age 2 a diagnosis can be considered “very reliable.” The parents said they were happy with Chase’s success at the learning center, but still had concerns for Jack because he was not speaking. Developing social and communication skills can be among the greatest challenge for individuals with autism, even if they are able to say a few words early on. “We didn’t know if he was ever going to talk,” Erika said. “That was my biggest fear. We just didn’t know.”Looking ahead, the parents are cautiously optimistic about Jack’s next educational move. He doesn’t handle change well, they said, and he likes to know his routine. Still, they expressed confidence that his time at the learning center has given him the skills he needs to be successful.4. How did Jack’s parents know he suffered from autism?A. They found the baby clever.B. They judged by their experience.C. They found he didn’t develop.D. They checked on him in the hospital.5. What did the parents think of the early intervention?A. It made no difference to the babies.B. It benefitted the babies greatly.C. It got their babies more disabled.D. It helped their babies speak fluently.6. What can we learn from the third paragraph?A. Autism can be confirmed at 18 months old.B. Jack’s parents were confident about his motor skills.C. Chase’s parents were doubtful about his developmentD. Jack’s parents worried about his language skills most.7. What is the text mainly talking about?A. Autism can be curedif parents take actions early.B. Parents should be confident about their children’s future.C. Early intervention in autism could improve children’s life.D. Communication skills should be developed as early as possible.CGlobal food demand will double by 2050, according to a new projection, and the farming techniques used to meet that unprecedented(空前的) demand will significantly determine how severe the impact is on the environment, researchers said.The study researchers warned that meeting the demand for food would clear more land, increase nitrogen(氮) use and significantly add to carbon dioxide and other greenhouse gas emissions.“Agriculture’s greenhouse gas emissions could double by2050 if current trends in global food production continue,” study researcher David Tilman, of theUniversityofMinnesota, said in a statement. “This would be a major problem, since global agriculture already accounts for a third of all greenhouse gas emissions.”The researchers studied various ways in which the increasing food demand could be mentioned. They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method, by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthy nations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, that number could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.8. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields9. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly10. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems11. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandDThe air is thin and we have to rest several times on the shore hike from camp. To our left, snow-coveredmountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can just make out a herd of graceful animals. This is why we stay here.Tibetan antelopes live mainly on the plains of Tibet. Watching them move slowly across the green grass, I'm struck by their beauty. I'm also reminded of the danger they are in. They are being hunted illegally for their valuable fur.My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve. The reserve is a safe place for the animals and plants of northwestern Tibet. To Zhaxi, protecting the wildlife is a way of life. “We're not trying to save the animals,” he says. “Actually, we're trying to save ourselves.”In the 1980s and 1990s the population of Tibetan antelopes dropped by more than 50 percent. Hunters were shooting antelopes to make money. Their living places were becoming smaller as new roads and railways were built.In order to save Tibetan antelopes, the Chinese government placed them under national protection. Zhaxi and volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope wasremovedfrom the endangered species list. The government, however, does not intend to stop the protection program since the threat to the Tibetan antelope has not yet disappeared. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.12. What can we learn from Zhaxi's words in paragraph 3?A. Protecting the animals can make money.B. Protecting the animals is protecting ourselves.C. He is not fond of protecting the animals.D. The reserve is only safe for wild animals.13. What is mainly talked about in paragraph 4?A. Why hunters hunt Tibetan antelopes.B. Why antelopes' living places changed.C. Why antelopes' number dropped greatly.D. Why the 1980s and the 1990s are unusual.14. What does the underlined word “removed” in the last paragraph probably mean?A. Deleted.B. Changed.C. Migrated.D. Recognized.15. What might be the future condition of Tibetan antelopes according to the last paragraph?A. They will be over-populated.B. They will be a threat to man and other wildlife.C. They will be on the endangered species list again.D. They will be in harmony with nature and humans.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。

A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tiny pieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.4. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.5. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.6. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.7. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingCBeing a teacher is a rewarding career when it comes to changing lives, but it’s obviously one that comes with plenty of stresses and difficulties too.Seeking help for a child who is so obviously in need isn’t easy. Often, you feel ignored by the government. You feel upset that there isn’t anything you could personally do to help a needy and sensitive member of your class.That’s exactly how Chelsea Haley, aged 24 at the time, felt when she met fourth-grade student Jerome Robinson while working for Teach forAmericainLouisianafor the first time.The pair didn’t get off to the best start, with Jerome, the “problem child”, almost drivingChelseafrom teaching. But whenChelseaput her foot down and became determined to work more closely with Jerome, she learned the cause of his rude behavior: a bad home situation.Chelseawas eager to help Jerome, and realized that he needed more than just academic support.By 2016, a year after meeting him, Chelsea had adopted (收养) Jerome and his brother Jace.Adopting a child doesn’t come cheap, andChelseaspent all the money in her bank to see the process through.In her first few years of raising the boys, she lived on credit cards and postponed her student loan.AsChelsealived with her two adopted sons, she worked hard to repay her debts. She took on extra tutoring jobs outside of school hours, moved in with her parents, and even delivered groceries for cash. Along the way, she was learning how to be the best mom to Jerome and Jace, cooking for them and cheering them on at football matches.And now, just five years later,Chelseacan proudly say that she has paid off nearly $50, 000 of debt. Now that she’s finally out of debt,Chelseahas plans to buy a house and save up for the boys’ college education.“It allows me to focus on the boys’ future,” she said. “Saving money for them, and not spending it on my past.”8.

His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood，he wasbetter off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.These are the findings of a 40-year study that followed the lives of 456 teenage boys fromBoston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence（能力）and came to feel they were worthwhile members of society, ” said George Vaillant, the psychologist（心理学家）who made the discovery. “And because they felt good about themselves, others felt good about them.”Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide varietyof people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.Working—at any age—is important. Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings（基础）of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn't everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”12. What do we know about John？A. He received little love from his family.B. He had few childhood playmates.C. He enjoyed his career and marriage.D. He was envied by others in his childhood.13. Vaillant’s words in Paragraph 2 serve as _______.A. a description of personal values and social valuesB. an analysis of how work was related to competenceC. an example for parents' expectations of their childrenD. an explanation why some boys grew into happy men14. Vaillant's team got their findings by _______.A. recording the boys' effort in schoolB. comparing different sets of scoresC. evaluating the men's mental healthD. measuring the men's problem solving ability15. What can be inferred from the last paragraph?A. Competent adults know more about love than work.B. Emotional health is essential to a wonderful adult life.C. Love brings more joy to people than work does.D.Independenceis the key to one's 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。

Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don't worry about it. Once, when trying a certain trick on the beam（横杆）, I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “Safe! Safe! Safe!” And that's what mattered—landing tricks, being a good skater.When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I'd given it up.When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I've traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch theskaters. Weaving（穿梭）among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded（滑）up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caughta few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”“Yeah,” I said. “Safe.”4. What can we learn about the author soon after he moved to London?A. He felt disappointed.B. He gave up his hobby.C. He liked the weather there.D. He had disagreements with his family.5. What do the underlined words “Safe! Safe! Safe!” probably mean?A. Be careful!B. Well done!C. No way!D. Don't worry!6. Why did the author like to spend time in Southbank when he returned to London?A. To join the skateboarding.B. To make new friends.C. To learn more tricks.D. To relive his childhood days7. What message does the author seem to convey in the text?A. Children should learn a second language.B. Sport is necessary for children's health.C. Children need a sense of belongingD. Seeing the world is a must for children.CMost animals living in crowded conditions have particularly strong immune systems, so it long puzzled researchers that honeybees do not.Part of the answer, discovered in 2015, is that queen bees vaccinate their eggs by moving parts of proteins from disease-causing pathogens to them before they are laid. These act as antigens totriggerthe development of a protective immune response in the developing young. But that observation raises the question of how the queen receives her antigen supply in the first place? Dr. Harwood wondered if the nurse bees were taking in parts of pathogens and passing them to royal jelly they were producing while eating the food brought to the hive.To test this idea, he teamed up with a group at theUniversityofHelsinki, inFinland, led by Dr Heli Salmela. Together, they collected about 150 nurse bees and divided them among six queenless mini hives equipped with baby bees to look after. Instead of honey, they fed the nurses on sugar water, and for three of the hives they added P. larvae, a bacterium causing a hive-killing disease, to the sugar water.In this case, to stop such an infection happening, Dr Harwood and Dr Salmela heat-treated the pathogens and so killed them in advance. They also labelled the dead bacteria with a fluorescent dye, to track them easily. And, sure enough, it was confirmed that parts of P. larvae were getting into royal jelly released by those bees which had been fed with the sugar water containing that.All told, these findings suggest that nurse bees are indeed, through their royal jelly, passing antigens onto thequeen for vaccinating her eggs. They also mean the nurses are vaccinating baby bees as well, because baby bees, too, receive royal jelly for the first few days after they come out.8. What does the underlined word “trigger" in Paragraph 2 probably mean?A. Cut out.B. Set off.C. Slow down.D. Put off.9. Which is the main experimental subject in Paragraph 3?A. Queen bees.B. Nurse bees.C. Bee eggs.D. Baby bees.10. Why was P. larvae added to the sugar water?A. To test if it would cause a hive-killing disease.B. To check how the bacterium would affect the hive.C. To see whether the target bees would favor the taste.D. To confirm the bees would pass pathogens to royal jelly.11. What is the text mainly about?A. How bees multiply.B. How antigens function.C. How bees get vaccinated.D. How immune system works.DYu Chenrui, 29, is a maker of automata (机关人偶) in Chengdu, Sichuan province. Automata are built to look like humans or animals and give the illusion (错觉) of being able to move ontheir own, “The art form amazes me, because it combines various skills, from storytelling to mechanics, and the pieces are built with a sense of humor,” Yu says. His creations have caught the attention of well-known artists and his fancy pieces of art have attracted collectors worldwide.Interested in handcrafts as a boy, Yu first encountered automata designed by Japanese artist Kazuaki at an exhibition in 2015 when he studied at the Communication University of China in Beijing. “It was like meeting a like-minded friend, ” Yu says, recalling the moment. As an art and design major, he began to learn the craft by himself and, with the support of his tutor, he kept studying and examining automata in school.When he graduated in 2016, Yu landed a job at an advertising agency in Beijing. He stayed on at the company for three years because, at that time, he was not sure that he could make a living out of his hobby. While working as a designer Yu kept exploring and advancing his skills in wood carving and mechanics. Eventually, despite the job’s good salary, it was not enough to make up for not following his true passion. Finally, in 2018, Yu quit his job and returned to Chengdu to open his automata workshop.To keep himself occupied while running his workshop, he planted blueberries, raspberries and cherries. He watered, weeded and added fertilizer (肥料) every day. “Daily routines helped me calm down and inspire my creativity, which resulted in an automaton called To Observe the Autumn,” Yu says.Over time, Yu’s reputation grew and his business flourished (兴旺). Many of Yu’s creations are built with a dash of wisdom, a sprinkle of humor and are inspired by observations of real life. Yu knows that there are many more creative ideas waiting to be expressed. “It feels quite good to be fully devoted to automata creation and I am still searching for myself.”12. What can we learn from the first paragraph?A. Yu is equipped with various skills.B. Yu is a person full of sense of humor.C Yu is now gaining recognition worldwide.D. Yu is following the latest trend in handcraft.13. Why did Yu quit his job in Beijing?A. He couldn't make a living out of it.B. He wanted to pursue his own dream.C. He missed his family in Chengdu.D. He thought he had a lot experience.14. According to Yu, what contributes to his creativity as an automata artist?A. The fruits he grows.B. Success of his business.C. His devotion to the job.D. Observation from daily life.15. Which of the following can best describe Yu’s story?A. There is no end to learning.B. Great hopes make great man.C. Actions speak louder than words.D. Experience is the mother of wisdom.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年西安高级中学高三英语一模试题及答案
2021年西安高级中学高三英语一模试题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AA Lifelong Devotion to Keeping People FedYuan Longping is a Chinese agricultural scientist and educator, known for developing the hybrid rice varieties.Yuan graduated from the Southwest Agriculture Institute in 1953 andbegan his teaching career at an agriculture school.In the 1960s, when a serious food shortage sweptChina, Yuan decided to devote himself to studying how to increase the yields of rice. He then began a lifelong connection with rice.Yuan succeeded in growing the world’s first high-yielding hybrid rice varieties in 1973, which could reach a yield of over 500 kg per mu (about 0.067 hectares), rising from the previous yield of only 300 kg per mu. For the next four decades, he continued to work on research and development of hybrid rice, achieving increasingly higher outputs. In 2020, hybrid rice developed by Yuan’s team achieved 1,500 kilograms per mu in two growing seasons, a new world record.InChina, where rice is the main food for the majority of the 1.4 billion people, the planting area of hybrid rice has reached 16 million hectares, or 57 % of the total planting area of rice, helping feed an extra 80 million people a year.Hybrid rice has also been grown in over 40 countries, including theU.S.,Brazil,India,Vietnam, thePhilippinesandMadagascar. The total planting area of the hybrid rice has reached 8 million hectares overseas.Even after a great success, Yuan never held himself back from making new breakthroughs. In 2017, his team started to grow seawater rice inQingdao. The rice was designed to grow in saline-alkaline land and survive even after being completely in seawater. His team planned to develop a type of seawater rice that could be planted in 6.67 million hectares of saline-alkaline land acrossChinato boost the country’s rice harvest by about 20 %. In 2018, Yuan’s team was invited to plant the saline-alkaline tolerant rice in experimental fields inDubai, which achieved huge success. In June 2020, his team started to grow seawater rice on a farm at an altitude of 2,800 meters in northwestChina’sQinghaiProvince. The experiment succeeded.Yuan had two dreams — to “enjoy the cool under the rice crops taller than men” and that hybrid rice could be grown all over the world to help solve the global food shortage.1. What made Yuan Longping decide to study rice?A. A serious food shortage.B. Agriculture development.C. His interest in the rice experiment.D. His wish to plant the tallest rice in the world.2. From the passage, we know that Yuan Longping ________.A. developed a variety of hybrid riceB. worked as a scientist after graduationC. started to grow seawater rice inDubaiin 2017D. grew the first high-yielding hybrid rice varieties in 19533. We can infer from the passage that Yuan Longping’s most outstanding qualities are________.A. modest and outgoingB. honest and creativeC. generous and optimisticD. responsible and devotedBWe interviewed two people, one who went from the country to the city and one who did the opposite.Janet Lincoln is a salesgirl who moved to St. Louisfive years ago. Here’s what Janet told us:“Five years ago I used to live in a small town called Lemon Falls. I grew up and went to high school there. After I graduated I worked in a supermarket. Lemon Falls had a population of about 800 people, and I knew every single one of them. They all knew everything about me, too. You couldn’t do anything without everyone in town knowing about it. The first chance I got I moved to St. Louis and I love it. I don’t know as many people now as I used to, but that’s OK. I have a few good friends, and I see them when I want to. I kind of like beinganonymous. I’d never go back to Lemon Falls.”Troy Henson had the opposite experience. He and his wife, Darla, and their two children moved from St. Louis to Bloomfield three years ago. Here’s what Troy told us:“The best thing we ever did was get out of St. Louis. Don’t get me wrong; St. Louis is as good a place as any other city, I suppose — if you like cities, that is. We don’t. Both Darla and I grew up in St. Louis. We met at college and got married. Then the kids came along and life got difficult. We didn’t know any of our neighbors. We both had good jobs, but it always seemed like there was never enough money. That all changed when we moved to Bloomfield. I don’t make as much money as I used to, but then we don’t have as many expenses as we did. We know our neighbors. Life is good. We’d never leave Bloomfield.”4. What troubled Janet when she was in Lemon Falls?A. She had no friends.B. There was no privacy.C. There was a lot of competition.D. She couldn’t find a well-paid job.5. What does the underlined word “anonymous” in Paragraph 3 mean?A. Alone.B. Prepared.C. Sociable.D. Unknown.6. Different from Janet, Troy ________.A. prefers country lifeB. moved to a bigger cityC. grew up in a smaller townD. knows little about his new neighbors7. What is Troy’s opinion on living in Bloomfield?A. It is a little boring.B. It is quite comfortable.C. It costs a lot of money.D. It creates a safe environment.CPeggy Whitson's job demands a daily twohour workout in a gym where weight has no meaning and the view changes at 17,000 miles an hour.Whitson makes it look easy. At 57, she is the oldest woman to fly in space, breaking the record last November, 2016, when she began her third longterm stay at the International Space Station. After returning home in September, 2017, the NASA astronaut feltmatter-of-factabout the age milestone.“It wasn't a record I was seeking for,” Whitson said. “I was 42 and 48 for my first two space flights. I feel lucky that I was able to get to do another one in my 50s. I don't think people should let age discourage them, even on those jobs that require some amount of physical fitness. The oldest man is John Glenn (at 77), and we've had male astronauts in their 60s before, so it's just a matter of time before women start flying in space at this age”.On the earth, she stays fit by weightlifting, biking, playing basketball and water skiing. She shared what it's like to live in microgravity: “It's like you're in a swimming pool, but you don't have to worry about breathing. If I push off from one side, I'm going to float to the other side. Every direction feels exactly the same, which is really hard for your brain to grasp, but it's amazing how fast you adapt.It's a big shock for the body to come back to Earth—everything is so heavy. We spend a lot of time getting used to being back in gravity again. Back pain was really the most dramatic for me this time. For me, coming home is harder than going up into space.”8.

It’s such a popular color1 today. Why would no country use it in their flag? The answer is really quite simple. Purple was just for too expensive.The color1 purple has been associated with royalty power and wealth for centuries. Queen Elizabeth I forbade anyone except close members of the royal family to wear it. Purple’s high status comes from the rarity and cost of the dye (染料)originally used to produce it. Fabric traders got the dye from a small sea snail (海螺)that was only found in the Tyre region of the Mediterranean. More than 10,000 snails were needed to create just one gram of purple; not to mention a lot of work went into producing the dye, which made purple dye so expensive.Since only wealthy rulers could afford to buy and wear the color1 , it became associated with the royal family. Sometimes, however, the dye was too expensive even for royalty. Third century Roman Emperor Aurelio famously wouldn’t allow his wife to buy a scarf made from purple silk because it cost three times its weight in gold. A single pound of dye cost three pounds of gold, which equals 56,000 dollars today. Therefore, even the richest countries couldn’t spend that much having purple on their flags.The dye became more accessible to lower-class about a century and a half ago. In 1856, 18-year-old English chemist William Henry Perkin accidentally created a man-made purple compound (化合物)while attemptingto produce an anti-malaria drug. He noticed that the compound could be used to dye fabrics, so he patented the dye, manufactured it and got rich. Purple dye was then mass-produced so everybody could afford it.Till now, a handful of new national flags have been designed and a few of them have chosen to use purple intheir flag. So don’t be making any bets just yet.12. Why was color1 purple expensive in the past?A. Because only royal families were allowed to wear purple.B. Because it took a long time to get purple dye from gold.C. Because purple was worth as much as its weight in gold.D. Because purple dye used to be rare and hard to produce.13. Why did Roman Emperor Aurelio forbid his wife to buy a purple scarf?A. Because of poor quality.B. Because of long tradition.C. Because of bad taste.D. Because of high price.14. What is purple's situation now?A. Purple has been widely used on national flags.B. Purple dye is now affordable to ordinary people.C. Royal family stop using purple because it’s toocommon.D. Fewer snails are used to produce purple dye than before.15. Which of the following would be the best title for the passage?A. No Purple Flags?B. Purple vs GoldC. How to Produce Purple Dye?D.

Then,when the summer came,trees could not tap deep sources of water that would normally have maintained them.Many valuable old trees died.When I volunteered on the Mount Rainier Tree Commission,I heard from many people concerned about their trees.We had little to offer them.That’s because public and private urban tree resources and programs were aimed almost entirely at planting trees and not at all maintaining trees. No state or province program that I could find provided any financial resources for maintaining tree health.Small and under-resourced cities such as ours were on their own.This is backward,Scientists are learning that large,old trees are the most valuable,especially in cities,.They put on wood fastest and take the most carbon out of the air.They harbor the most wildlife. They can lower summer temperatures by20degrees or more.In a recent study,researchers found that Boston would get more benefit from keeping the trees it has alive than from planting new trees. There’s the reason to think this finding would apply in other cities,too.Now,our public and private tree programs often ignore old trees until it is too late.As long as we abandon our old trees,planting more is merely to keep pace with growing losses.We want trees to help protect us,but we leave them unprotected.Consider this in the human world;Nobody would send a baby into the world and expect it to just make it,Children need caring for and it's why we have schools and child health-insurance programs,We could get so much more out of our trees if we just put a little more into them.24.What does the underlined part in paragraph1suggest?A.Strong determination to plant trees.B.Real regret at growing old trees.C.Great concern about tree problems.D.Deep love for valuable old trees.25.Why was the author almost powerless to help people worried about their trees?A.The urban tree programs were faced with financial problems.B.The author's knowledge of maintaining tree health was limitedC.The focus of the tree resources and programs was on tree planting.D.The organization the author volunteered on was short of tree experts.26.The author argues in paragraph3by________.paring different casesB.presenting research findingsC.referring to scientists'sayingsD.carrying out some experiments27.Why does the author give the example of nursing babies in the end?A.To stress the importance of tree insurance programs.B.To show the close connection between trees and babies.C.To advocate protecting trees as humans care for babies.D.To persuade human beings to pay more attention to babies.CTime and how we experience it have always puzzled us.Physicists have created fascinating theories,but their time is measured by a pendulum(钟摆)and is not psychological time,which leaps with little regard to the clock or calendar.As someone who understood the distinction observed, "When you sit with a nice girl for two hours it seems like a minute,but when you sit on a hot stove,a minute seems like two hours.”Psychologists have long noticed that larger units of time,such as months and years,fly on swifter wings as we age.They also note that the more time is structured with schedules and appointments,the more rapidly it seems to pass.For example,a day at the office flies compared with a day at the beach.Expectation and familiarity also make time seem to flow more rapidly.Almost all of us have had the experience of driving somewhere we’ve never been before,Surrounded by unfamiliar scenery,with no real idea of when we'll arrive,we experience the trip as lasting a long time.But the return trip, although exactly as long,seems to take far less time.The novelty of the outward journey has become routine.When days become as identical as beads(小珠子)on a string,they mix together,and even months become a single day.To counter this,try to find ways to interrupt the structure of your day-to stop time,so to speak.Learning something new is one of the ways to slow the passage of time.One of the reasons the days of our youth seems to be full and long is that these are the days of learning and discovery.For many of us learning ends when we leave school,but this doesn't have to be.28.What is the underlined sentence in paragraph1used to show?A.Psychological time is quite puzzling.B.Time should not be measured by a pendulum.C.Physical time is different from psychological time.D.Physical theory has nothing to do with the true sense of time.29.Why do units of time fly faster as we grow older?A.Our sense of time changesB.We spend less time at the beach.C.More time is structured and scheduledD.Time is structured with too many appointments.30.What does"novelty"in paragraph3probably mean?A.ExcitementB.unfamiliarity.C.Imagination.D.Amusement.31.What is the purpose of the passage?A.To give various explanations about time.B.To describe how we experience time physically.C.To show the differences of two kinds of time.D.To explain why time flies and how to slow it down.DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste)currently takes up5percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank.They end up in places like Agbogbloshie on the outskirts of Ghana's capital,Accra.It is the biggest e-waste dump in the world,where10,000informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a1989treaty aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The E-waste industry, however,circumvents the regulations by exporting e-waste labelled as“secondhand goods"to poor countries like Ghana,knowing full well that it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising:smartphones contain chemicals like mercury(水银),lead and even arsenic(砷)Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that's about220times greater than a limit set by the European Food Safety Authority(EFSA),Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all,since some of Ghana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers'waste.For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone,as there is an almost limitless consumer demand for hardware,especially when governments’green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair,reuse and recycling of hardware profitable,or at least cost-neutral.32.What can we infer from paragraph2?A.Electronic products need improving urgently.B.Electronic waste is too complex to get fully recycled.C.Electronic waste requires more landfill sites across Ghana.D.Electronic pollution is a burning question in Agbogbloshie.33.What does the underlined word"circumvents"in paragraph3mean?A.TightensB.AbolishesC.AvoidsD.Follows34.What should be the biggest concern according to the text?A.The violation of EFSA’s standardB.The lack of diversity in Ghana s exports.C.The damage to chickens immune systemD.The threat of polluted food around the world35.What does the author think is the best solution to the e-waste problem?A.Manufacturers'developing a sustainable hardware economy.ernments'adjusting their green policies about e-waste.C.Reducing customers'demands for electronic products.D.Letting governments take on the main responsibility.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
