2020-2021学年江苏省苏州中学高三英语一模试卷及答案解析

2020-2021学年江苏省苏州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AThere have been many great painters in the rich history of Chinese art. Here are four of the greatest painters from China.Li Cheng (919—967, Five Dynasties and early Song Dynasty)Li Cheng contributed greatly to one of the golden ages of landscape paintings in world history. During his time, he was considered the best landscape painter ever. He is remembered especially for the winter landscapes he created and for simple compositions of tall, old evergreens set against a dry landscape. Several of his paintings are in thin ink which gives them a foggy appearance.Fan Kuan (990—1020 , Song Dynasty)Fan Kuan began his career by modeling Li Cheng's work but later created his own style, claiming that the only true teacher was nature. His finest workTravelers among Mountains and Streamsis a masterpiece of landscape painting and many future artists turned to it for inspiration.Qi Baishi (1864-1957)One of the greatest contemporary Chinese painters, Qi Baishi is known for not being influenced by Western styles like most painters of his time. He can be considered as the last great traditional painter of China. He painted almost everything from insects to landscapes. He is regarded highly in Chinese art for the freshness that he brought to the familiar types of birds and flowers, insects and grass.Wu Guanzhong (1919—2010)Widely considered as the founder of modern Chinese painting , Wu Guanzhong has painted various aspects of China, like its architecture, plants, animals, people and landscapes. Wu went on to combine Western and Chinese styles to create a unique form of modem art. In 1992, he became the first living Chinese artist whose work was exhibited at the British Museum.1.What do we know about Li Cheng?A.He loved landscape paintings.B.He copied many artists' work.C.His work gained worldwide recognition.D.He was considered as Fan Kuan's teacher.2.What is the main feature of Qi Baishi's paintings?A.They have foggy appearances.B.They lack diversity in the theme.C.They come under Western influence.D.They show advanced traditional painting skills.3.What did the four Chinese painters have in common?A.They were all modern painters.B.They all created landscape paintings.C.They were all impacted by Western art.D.They were all pioneers intraditional art history.BElonMusk is a symbol of passion, hard work and success. A person may work hard in his life, but when hard work goes along with passion and a new idea, then something is created that astonishes the world. As the founder of big companies like PayPal, SpaceX, and Tesla Motors, Elon Musk is a guide and inspiration for the youth around the world.Elon Musk was born on June 28,1971 inPretoria,South Africa. He was the eldest of three children. His father Errol Musk, a British-born South African, was an engineer. Musk spent his childhood inSouth Africaand at the age of 9, he got his first personal computer. This got Elon interested in programming and he started to learn on his own. At the age of 12, he made his first computer game, Blaster, which earned him $500 when he sold the source code to a magazine.When he was 17, he decided to leave home and had wanted to move to theUnited Statesafter graduating from a secondary school inPretoria. However, he was unable to move to theUnited States. In 1989, Elon Musk moved toCanada, where his mother’s s lived. After obtaining Canadian citizenship, Musk went toMontreal. Due to a lack of money, he found a low-paying job. At the age of 19, he enteredQueensUniversityinKingston,Ontario, studying there for two years. Finally, in 1992, his dream came true—he moved to theUnited States.As a teenager, Musk struggled with depression. But then he realized that the most important thing was presenting himself with the right questions. The day he started doing this, everything started to get easier.Musk thought that a human being had to expand the limits of his consciousness—to ask the right questions and get answers to them; thus he asked the best question of all: what will have the greatest impact on the futureof humans? Musk found that these things were the Internet and space exploration.The life of Elon Musk is inspiring. He found success on the Internet, without much formal learning. By reading books and using his willpower and dedication, he reached a level of knowledge that is difficult to imagine. He did not give up until he achieved his dreams. Elon Musk truly stands out among other billionaires because of his leadership abilities, positive attitude, ability to know when to take risks, and belief in futuristic technologies.4. According to the passage, Elon Musk gained knowledge of computer by ________.A. teaching himselfB. learning from his fatherC. taking online coursesD. studying inQueensUniversity5. What made things easier for Elon Musk when he suffered from depression?A. Expanding knowledge by reading books.B. Asking himself the right questions.C. Achieving success on the Internet.D. Designing computer games.6. What can we learn from the passage?A. It’s never too late to learn.B. Youth means limitless possibilities.C. Where there’s a will, there’s a way.D. He who doesn’t advance falls backward.7. Which words can best describe Elon Musk according to the passage?A. Optimistic and generous.B. Ambitious and determined.C. Independent and helpful.D. Adventurous and realistic.CAt any moment, about half the world’s population is wearing denim(牛仔布)clothes. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.Sam Athey, one of the study’s authors, says, “Even though denim is made of a natural material—cotton, it contains chemicals.” Cotton fibers were treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color1 .Athey and her team washed jeans and found that about 50,000 microfibers came off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent ofthem. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering the water environment.Denim microfibers showed up in sediment(沉淀物)from the Great Lakes. More of these fibers polluted a series of shallow lakesin southern Ontario. They even turned up in sediment from the Arctic Ocean in northernCanada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.“Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,” Athey says. “An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after wearing them every couple of times, but most jean companies recommend washing them no more than once a month. “The solution is not that you shouldn’t wear jeans,” she says. “We need to buy fewer denim clothes and only wash them when they truly need it.”8. Which of the following is TRUE according to the passage?A. Chemicals are contained in natural cotton.B. Chemicals can make denim color1 ful.C. Chemicals prevent fibers from falling.D. Chemicals can make the life of denim longer.9. What does the underlined word “them” in Paragraph 3 refer to?A. Denim.B. Sediment.C. Microfibers.D. Chemicals.10. What does the author mainly want to tell us through Athey’s words ?A. To avoid wearing jeans.B. To reduce denim consumption.C. To wash jeans more often.D. To limit input in denim production.11. In which section of a magazine might the text be found?A. Science.B. Entertainment.C. Tourism.D. Geography.DThefirst thing we notice about new people are their faces. The next time we see these people, we remember them because we remember their faces. This seems like a simple process. However, scientists found that it is not such a simple process. The section of the brain that is responsible for face recognition seems to work differently for different people. Some people have great difficulty remembering and recognizing faces, while others almost never forget a face.Normal babies are born with a natural ability to recognize faces. In fact, their face recognition abilities are much better than their parents. Babies are most highly skilled at face recognition at six months. But by nine months, they lose this skill. By nine months, a baby’s face-recognition skills are about the same as an adult’s.Unfortunately, some people are not born with this ability to recognize faces. The part of the brain that is responsible for face recognition doesn’t work for them. This condition is called face blindness. People with verysevere face blindness cannot even recognize their own faces. In fact, people with this condition can sometimes be frightened when they look in the mirror. They don’t recognize their own face, so for a second they are startled when they see this unfamiliar face.Face blindness is not always severe. Scientists believe up to 10 percent of the population may be affected by face blindness to some degree, yet many people with mild face blindness might not even know they have it. They have no reason to know they are different from anyone else until someone points it out. This is similar to people with color1 blindness. Colorblind people can’t see the difference between certain color1 s such as red and green, until someone tells them that green and red are two different color1 s.There is no cure for face blindness. So for the time being, people with face blindness need to find simple techniques to compensate for their problem. They can try to recognize people by their hairstyle, their voice, or their glasses. Hopefully, in the future as scientists learn more about this condition, they may find a cure.12. What is the first paragraph mainly about?A. The way to improve one’s face-recognition skills.B. The simple process of the brain to recognize others’ faces.C. The fact that some people have face-recognition problems.D. The importance of face recognition in human communication.13. When do children have the best face-recognition skills?A. At birth.B. Half a year old.C. Nine months old.D. In adolescence.14. What does the underlined word “startled” in the 3rd paragraph probably mean?A. Depressed.B. Confused.C. Embarrassed.D. Surprised.15. What does the author think of the problem of face blindness?A. People need to take it seriously.B. Certain techniques can make up for it.C. It will be cured in the near future.D. It has the same effect with color1 blindness.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2020-2021学年苏州市第一高级中学高三英语一模试题及参考答案

2020-2021学年苏州市第一高级中学高三英语一模试题及参考答案

2020-2021学年苏州市第一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.BMy first week working in a restaurant, one of the servers said something that stuck with me: Everyone should work in a restaurant for at least a year. At the time, I didn't get it, but I took the advice to heart and worked in restaurants on and off for the next eight years. Before realizing it, I mastered many important skills, one of which is communication skill.When I was little, I was so shy that I used to hide behind my mom whenever someone spoke to me. And when I first started in restaurants, I had two personalities: Restaurant Lizzy and Home Lizzy. It was easier to pretend to be a different person while at work, since it was so different from who I actually was. But gradually, the skills I learned working in restaurants helped Home Lizzy come out of her shell in the real world.When you work in a restaurant, you don't have the luxury of hiding behind your parents to avoid talking to people. I'm still 110% an introvert, but restaurant work helped me communicate. Working in a restaurant not only helped me speak clearly, deliberately and directly but also taught me how to talk about almost everything. Some guests don't want their servers to interact too much with them, and that's fine. But some sit at the bar simply to chat with you. You learn how to judge your guests' level of interest in communicating with you, and how to exit a conversation at the appropriate time.My restaurant work is something that I'm most proud of and I know I wouldn't be the person I am today without those eight years of experience. If you're still on the fence about working in a restaurant for that long, start with one year. I doubt that you'll look back.4. What did the writer think of the server's words?A. Impressive.B. Ridiculous.C. Amusing.D. Logical.5. What do we infer from Paragraph 2?A. The writer tried different jobs.B. The writer became more sociable.C. The writer used an invented name.D. The writer had a hard time at work.6. Which of the following best describes the writer's restaurant work?A. Boring.B. Relaxing.C. Worthwhile.D. Unchallenging.7. What message does the writer try to convey in this passage?A. A strong-willed soul can reach his goal.B. Things are difficult before they are easy.C. Communication skills advance your career.D. Restaurantwork helps to achieve a better self.CCoke was introduced by the Coca Cola company in 1886, making it a rather true andtested favorite of generations of people in over 200 countries. This list should give you some ideas on how to get more from your coke than usual.. Coca Cola is an excellent rust buster (除锈剂). If you have a bunch of small rusty objects, put them in coke overnight and give them a goodscrubin the morning. Coke helps to break down the rust, making cleaning much easier. Be sure to throw out the used coke when you are done with it or you might be taking a trip to the doctor.. Like the previous item, the citric acid (柠檬酸) in coke makes for an excellent window cleaner. This is especially useful for car windows. Pour a can of coke over the window and rub the window, then wipe it off with a wet cloth to remove any sugary matter from the sugar in the drink. As coke is fullof sugar, you should clean the sticky matter off the window glasses, or it will be not a cleaner but a dirt.. For those of you who live in areas where skunk (臭鼬) smells can be an issue from time to time, one can of coke added to water with detergent (清洁剂) really helps to break the smell down. If you have been sprayed, stand in the shower and cover yourself from head to toe with coke — wait for a few minutes, then wash yourself with a shower. Coke is an excellent hair treatment so you get two tips for the price of one with this item!. Pots can sometimes get black on the bottom. The black is almost impossible to remove; this is caused by over-cooking. To remove the black and renew your pot, pour in a can of coke (or as much as you need to cover the blackened area by an inch) and put it on the stove on a low heat. After an hour or so, wash the pot as normal.8. What does the underlined word “scrub”in Paragraph 2 probably mean?A. Start.B. Cleaning.C. Shake.D. Example.9. What is important while using coke to clean car windows?A. Use a dry cloth.B. Rub the window lightly.C. Don’t pour too much coke.D. Clean the sugary matter thoroughly.10. For which purpose does coke have to be mixed with other material?A. To get rid of the black on the pot.B. To breakdown the rust,C. To remove smells.D. To clean windows.11. What type of writing is this text?A. An advertisement.B. A review.C. A news report.D. A practical guide.DAn anti-obesity program for Australian girls didn’t lead to any improvements in their diet, physical activities or body weight a year later, according to a new report.Findings from the school-based intervention (介入), which involved exercise sessions and nutrition workshops for lower-income girls, are the latest disappointment in a lot of research attempting tohead offadult obesity and the disease risks that come with it.Especially during the middle-and high-school years, girls’ physical activity reduces obviously, according to lead researcher David Lubans, from theUniversityofNewcastleinNew South Wales,Australia. He said, “In the future we need to make the programs more interesting and exciting and present information in a way that is meaningful to adolescent girl.”Lubans and his workmates conducted their study in 12 schools in low-income areas ofNew South Wales. At the start of the study, girls in both groups weighed an average of close to 130pounds, with about four in ten considered overweight. Over the next year, adolescents in the intervention group were given pedometers (计步器) to encourage walking and running and invited to nutrition workshops and regular exercise sessions during the schoolday and at lunchtime. Participation in some of those activities were less than ideal. For example, the girls went to only one-quarter of lunchtime exercise sessions, and less than one in ten completed at-home physical activity or nutrition challenges, the researchers reported. At the end of the year, girls in both groups had gained a similar amount of weight and there was no difference in their average body fat.Preventive medicine researcher Robert Klesges said that although some anti-obesity programs have helped adults lose weight, the teen population has always been a source of failure for researchers. “The common belief is: nothing works,” he said. “And we have got to get beyond that.”“We need to think outside the box,” said Klesges, who wasn’t involved in the new study. “That could include learning from what has worked in adult studies, such as giving meal replacement drinks or prepared foods to teens who have trouble making changes to their diet. Or, it could mean using a “step-care” method — rather thanresearchers or their doctor telling them to keep doing the same thing.” Klesges said.12. The underlined words “head off” in Paragraph 2 can best be replaced by “________”.A. damageB. defendC. preventD. affect13. The methods used in the program to stop obesity don’t include ________.A. walking and runningB. inviting them to nutrition workshopsC. joining exercise sessions regularlyD. giving meal replacement drinks14. The main reason for the failure of the anti-obesity program is probably that ________.A. the participants didn’t take an active part in itB. the program was not interesting and exciting to participantsC. the participants didn’t get extra nutrition or exercise helpD. the program didn’t pay attention to healthy exercise15. What can be inferred from the last paragraph?A. As researchers, it is important to have creative research methods.B. Researchers need to give meals or prepare foods to participants.C. Teen girls have no difficulty in making changes to their diet.D. Some ant-obesity programs have not helped adults lose weight.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。
