www.ks5u.com 太原五中2019—2020学年度第二学期3月摸底考试高 三 英 语出题人、校题人：宋向军、张晓佳、申玲、王芳 (2020.3.28)第二部分 阅读理解（共两节，满分60分）第一节 （共15小题；每小题3分，满分45分）阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。AWhat if you could take your drawing pen and simply scan any color you want and then turn around and draw with it? This new pen design allows you to do that. That is Scribble. And it’s very easy to use.·How does Scribble work?The built-in RGB sensor (传感器) lets you easily get any color — simply point it at an object and press the button! Red, green and blue inks are then mixed — much like in a traditional printer — to create your desired color.·Different tipsThe Scribble Pen (for paper) comes with three different sizes of drawing tips. Scribble is perfect for both drawing and writing. The Scribble Stylus Pen comes with two different tips — hard tip and soft tip. It works on more than just paper; it can be used for drawing or writing on your mobile device.·Rechargeable batteryScribble’s battery is rechargeable and lightweight. The Scribble Pen’s battery lasts seven hours. And the Scribble Stylus Pen’s battery lasts as long as 15 hours.·PriceThe regular price of a Scribble Pen is US$400. Now, you can have it at 40% off the regular price. And you can have a Scribble Stylus Pen at US$119 (save US$80). You also need to pay US$15 for postage. Remember to choose the color you want. At present, we offer five colors for you to choose from. If you are an artist, you really need a pen like this. It’s the last pen you will ever need to buy.To learn more information about the products you can visit our website.What can we learn about Scribble from the passage?A. It is connected to a printer.B. It is lighter than an ordinary pen.C. It doesn’t need electricity to work.D. It can be used for both drawing and writing. 2. Which is true about the Scribble Stylus Pen?A. It works best on paper.B. It can create five colors at present.C. It is initially designed for mobile devices.D. It has a better battery life than the Scribble Pen.3. If you buy a Scribble Pen now, how much should you pay in total? BBIt was a nervous time. World War II had started, and British ships were always watching for German submarines called U-boats. The ship Ben Lomond had left Cape Town, South Africa, with a crew of 55, including a young officer named Poon Lim.On November 23, 1942, the worst fear came true. The Ben Lomond was attacked by a U-boat. Within minutes the boat was sinking. Poon Lim grabbed a life jacket and leaped over the side. He swam rapidly away from the ship in case it exploded. Sure enough, it let out a large boom and sank beneath the waves. For two hours Poon Lim struggled in the water. Once he almost got onto a life raft with five other sailors, but it got away from his grasp. Then he saw another life raft that was empty, swam to it, and climbed aboard. He found a few cans of biscuits, a water jug, some flares, and a flashlight, which could be enough supplies for about a month.Day after day Poon Lim had his few biscuits and a couple of sips of water. He searched the horizon for ships. Twice he leaped up to shout and wave when he saw help coming. Once he saw a freight ship. It passed him. At a later time, he saw a United States Navy plane. It flew low over the raft but then disappeared. Still later a U-boat spotted him but for some reason left him alone.Poon Lim knew he needed to stay strong. He couldn’t get much exercise on an eight-foot-square raft, but he could swim. A couple of times a day, he circled the raft, always watching for sharks. Soon his food and water ran low. He knew that drinking seawater would make him sick, so he tore off the canvas cover on his life jacket and set it out to catch rainwater. Then he took apart the flashlight and used a wire inside to make a fishhook. For months Poon Lim drifted, catching fish and sometimes birds. One time he even caught a shark. Finally, after 130 days, he noticed that the color of the water was changing. Two days later, on his 133rd day, he saw a boat. Three sailors in a small sailboat picked him up and took him to Belem, a city on the coast of Brazil. Poon Lim had crossed the Atlantic Ocean.No one ever had survived longer on a raft at sea. Poon Lim received many honors, including Britain’s highest award. A booklet of his survival methods was put into every British life raft.What happened just after Poon Lim’s ship was hit?A. It immediately exploded. B. Poon Lim jumped over the side. C. Poon Lim found a life raft.D. The U-boat picked up survivors.5. What did Poon Lim do just after his food and water ran low?A. He jumped up and down and waved, hoping to attract help.B. He went swimming, hoping to find some fish.C. He made a rain catcher and some fishing equipment.D. He spotted a United States Navy plane.6. Which of these things happened last? A. Poon Lim noticed that the water had changed color. B. Poon Lim landed in a Brazilian city. C. Some sailors picked up Poon Lim. D. Poon Lim caught a shark with his fishhook. 7. Why was Poon lim presented with many honors?A. He had voyaged the longest time on the Atlantic Ocean.B. He managed to spend 133 days on a life raft with determination.C. He had a knowledge of survival methods on the sea.D. He didn’t surrender himself to German U-boats. CFollowing the outbreak of the novel coronavirus pneumonia (NCP), also named COVID—19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing—the NCP’s symptoms (症状) are similar to the common cold or the flu, but it’s potentially more dangerous. Viruses could be deadly, like HIV and Ebola (埃博拉). But what are viruses? How can they cause so much trouble? Viruses are non-living organisms (有机体) approximately one-millionth of an inch long. Unlike human cells or bacteria, they can’t reproduce on their own. Instead, they invade (入侵) the cells of living organisms to reproduce, spread and take over. Viruses can infect every living thing — from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human life. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger (引起) no noticeable reaction. Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system. But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. “Tracing the origins of viruses is difficult,” Ed Rybicki, a virologist at the University of Cape Town in South Africa, told Scientific American, “because viruses don’t leave fossils (化石) and because of the tricks they use to make copies of themselves within the cells they’ve invaded.” However, there are three main hypotheses (假说) to explain the origin of viruses. First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells. For the time being, these are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most reasonable explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.8. What can we learn about viruses from the text? A. Viruses have nothing to do with the common cold. B. Viruses are really small living organisms. C. Viruses can’t reproduce unless they find a host cell. D. Viruses enter our bodies mainly through the mouth, nose and hair.9. Which of the following might explain the origin of viruses? A. They evolved from the fossils of large organisms. B. They evolved from parasites into independent organisms. C. They evolved from the T-cells in animals. D. They evolved along with their host cells.10. What can we conclude from the text? A. Viruses live longer in human host cells than in animals’. B. Viruses will become more like bacteria as they evolve. C. It may take a long time to understand the origin of viruses. D. The author is optimistic about future virus research.11. What’s the best title of this passage?A. The Mystery of Virus EvolutionB. The Invasion of Deadly Viruses.C. The Reaction of Viral InfectionD. The Future Studies of Viruses DThey make a guest appearance in at least half of the articles on Medical News Today. They are responsible for many of the biggest breakthroughs in medicine. However, the humble lab mice also shoulder much of the blame when the failure of drugs to translate from animal models to humans keeps worrying the whole of medical research. Should scientists abandon lab mice altogether?Mice were introduced into the lab back in the 1920s. An ambitious young American geneticist Clarence Cook Little strongly believed that cancer was an inheritable (有遗传性的) disease, and that mice were the ideal subjects for his experiments.Other animals were, and still are, used to study disease. Cats and dogs are popular, as well as chimpanzees. Of course, ethical (伦理的) considerations get more complicated the further up the food chain you go. And mice are in sufficient numbers for researchers to conduct thousands of trials. Add to that the problem of cost: A standard lab mouse costs about $20---far cheaper than a healthy cat or dog. So their importance in scientific research has become well-established.We share more than 97 percent of our working DNA with mice, a consequence of a shared ancestor 75 million years ago. This similarity has been both a blessing and a curse. While we share many basic biological processes, it is the three percent of the genes which set us apart from mice that can have a big influence on how our bodies work.Mice may not always be the perfect model for understanding our own bodies, but they do hold real value to researchers. Their usefulness will only increase as scientists work out better ways to modify (修改) their genes to compensate for their shortcomings. The difficult part of the issue may be that researchers need to be more critical as they evaluate the type of model that is best for their experiment. In the end, the story of scientists’ relationship with lab mice will possibly be one of gradual advances to improve an imperfect system. This is exactly how most scientific research progresses — by critically examining what we know to expand our knowledge of what we do not.12. What does the underlined word “they” in the first paragraph refer to?A. American geneticists B. cats and dogs C. lab mice D. breakthroughs in medicine13. Paragraph 4 mainly answers the question “________?” A. Why do drugs that work in mice fail when tried in humans B. Why are mice the ideal subjects for medical research C. Why do we and mice share more than 97% of our working DNA D. How can we understand our own bodies by studying lab mice14. Which of the following statements is TRUE according to the passage? A. Mice are in sufficient numbers because they are at the lower part of the food chain. B. Many scientist are considering stopping the use of lab mice. C. More genetically modified mice will be used in medical research in the near future. D. It will become easier for researchers to choose the proper type of lab mice.15. What is the author’s attitude to the use of lab mice? A. Disappointed B. Supportive C. Indifferent D. disapproving第二节 （共5小题；每小题3分，满分15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。选项中有两项为多余选项。Think about how much reading you do everyday. When you look at it, you might find that reading is the work-related skill that you use most often! ___16___ After all, if we can read and comprehend textbooks, then aren’t we good readers? Maybe not. Given the time that reading consumes, it may be a skill that we can and should improve.___17___ It means getting faster and more efficient at reading, while still understanding what you’re reading. Although you spend a good part of your day reading, have you ever thought about how you read? How do your eyes make sense of the shapes of the letters, and then put those letters together to form sentences that you can understand?Reading is quite a complex skill. It was previously believed during reading, both eyes focus on particular letters.___18___ Scientists now believe that the eyes lock onto different letters at the same time, usually two characters apart. Your brain then fuses (融合) these images together to form a word. This happens very swiftly, as we look through pages of text！Many people read at an average rate of 250 words per minute. ___19___ Imagine, then, if you could double your rate to 500 words per minute. ___20___ You could then spend the saved time on other tasks, or take a few extra minutes to relax. Another important advantage of speed reading is that it allows one to better comprehend the overall structure of an argument. This leads to better “big picture” understanding, which can greatly benefit your work and career.A. Recent research shows this isn’t the case.B. Speed reading has a great many benefits.C. You should practice to improve your reading speed.D. But what does becoming a better reader involve?E. You could read all of this content in half the time.F. It’s also a skill that most of us take for granted by the time we reach age 12.G. This means that an average page in a book or document takes 1-2 minutes to read. 第三部分 语言知识运用（共两节，满分55分）第一节 （共20小题；每小题2分，满分40分）阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。When I tell people I wrote a book with my dad, they usually say, “It must be nice to think of the legacy (遗产) you created with someone who means so much to you.” This was a 21 idea, but it was not the way I, or my dad, ever thought about the cooperation. Though we created something we’re 22 , “nice” is not the word either of us uses to 23 the process. “It was more confrontation (对抗) than 24 ,” my dad likes to say. I agree.When we landed a book deal, we began a writing 25 that was more difficult than either of us had 26 , but also far more rewarding.For almost three years, we met once or twice a week at my parents’ house and talked daily to plan and 27 each chapter. After these meetings, one of us would write a 28 draft that the other would build on. I wanted the book to 29 on positive vices (不良习惯). 30 , my dad felt the book should include chapters dealing with things like walking and spending time with family. Ultimately, I saw it his 31 . He said the book was about more than just good vices. It was about 32 people to enjoy life in healthy ways.Writing this book was a(n) 33 that our family members share not only our faults but also our strengths. My dad is smart, funny, critical and caring. He has a strong passion for the truth. I hope I share these great 34 . For this book, he researched each topic with 35 I’d never seen from him, and he insisted that we constantly 36 and critically analyze every piece of information. He was 37 to cooperate on a book, not because he couldn’t write one on his own, but because he believed that we could create something 38 together than we could alone.I’m not sure 39 our cooperation led to better writing, but it led to a better writing experience. Writing this book was difficult, sometimes more difficult than past projects, but it was never 40 .第二节 （共10小题；每小题1.5分，满分15分）阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。Can you imagine the world full of crying and shouting, ___41___ (cover) in darkness? However, it’s not just a joke. It’s a real description of a world without happiness and __42___ (laugh).If you compare our life ___43___ a pie, what would you put in if you were in charge of making the pie? ___44___ (obvious), many people would add as much happiness as possible. Do you know why? It’s ___45___ happiness stands for sweetness in most people’s minds.Don’t think of it just as a comparison. Happiness is a flower living in the sunshine, and ___46___ is not difficult to reach for it. We have a variety of ___47___ (emotion) like sadness, anger, fear, enthusiasm and happiness, and they all appear naturally when something ___48___ (affect) our feelings. So, if we can change our attitude to things in the world, we can certainly adjust our emotions. It means that we can choose to be happy if we want to, as long as we view everything in ___49___ positive way.If we can be happy, why not choose to be? Let’s try together to create a world filled with ___50___ (smile) faces and sunshine. 第四部分 写作（共两节，满分35分）第一节 短文改错（共10小题；每小题1分，满分10分）假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。文中共有10处语言错误，每句中最多有两处。每处错误仅涉及一个单词的增加、删除或修改。增加：在缺词处加一个漏字符号（∧），并在其下面写出该加的词。删除：把多余的词用斜线（\）划掉。修改：在错的词下划一横线，并在该词下面写出修改后的词。注意：1. 每处错误及其修改均仅限一词；2. 只允许修改10处，多者（从第11处起）不计分。Yesterday afternoon, I felt illness all of a sudden.

While we share many basic biological processes, it is the three percent of the genes which set us apart from mice that can have a big influence on how our bodies work.Mice may not always be the perfect model for understanding our own bodies, but they do hold real value to researchers. Their usefulness will only increase as scientists work out better ways to modify (修改) their genes to compensate for their shortcomings. The difficult part of the issue may be that researchers need to be more critical as they evaluate the type of model that is best for their experiment. In the end, the story of scientists’ relationship with lab mice will possibly be one of gradual advances to improve an imperfect system. This is exactly how most scientific research progresses — by critically examining what we know to expand our knowledge of what we do not.12. What does the underlined word “they” in the first paragraph refer to?A. American geneticists B. cats and dogs C. lab mice D. breakthroughs in medicine13. Paragraph 4 mainly answers the question “________?” A. Why do drugs that work in mice fail when tried in humans B. Why are mice the ideal subjects for medical research C. Why do we and mice share more than 97% of our working DNA D. How can we understand our own bodies by studying lab mice14. Which of the following statements is TRUE according to the passage? A. Mice are in sufficient numbers because they are at the lower part of the food chain. B. Many scientist are considering stopping the use of lab mice. C. More genetically modified mice will be used in medical research in the near future. D. It will become easier for researchers to choose the proper type of lab mice.15. What is the author’s attitude to the use of lab mice? A. Disappointed B. Supportive C. Indifferent D. disapproving第二节 （共5小题；每小题3分，满分15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。选项中有两项为多余选项。Think about how much reading you do everyday. When you look at it, you might find that reading is the work-related skill that you use most often! ___16___ After all, if we can read and comprehend textbooks, then aren’t we good readers? Maybe not. Given the time that reading consumes, it may be a skill that we can and should improve.___17___ It means getting faster and more efficient at reading, while still understanding what you’re reading. Although you spend a good part of your day reading, have you ever thought about how you read? How do your eyes make sense of the shapes of the letters, and then put those letters together to form sentences that you can understand?Reading is quite a complex skill. It was previously believed during reading, both eyes focus on particular letters.___18___ Scientists now believe that the eyes lock onto different letters at the same time, usually two characters apart. Your brain then fuses (融合) these images together to form a word. This happens very swiftly, as we look through pages of text！Many people read at an average rate of 250 words per minute. ___19___ Imagine, then, if you could double your rate to 500 words per minute. ___20___ You could then spend the saved time on other tasks, or take a few extra minutes to relax. Another important advantage of speed reading is that it allows one to better comprehend the overall structure of an argument. This leads to better “big picture” understanding, which can greatly benefit your work and career.A. Recent research shows this isn’t the case.B. Speed reading has a great many benefits.C. You should practice to improve your reading speed.D. But what does becoming a better reader involve?E. You could read all of this content in half the time.F.

We live in dormitories, each of which should include no more than four students. With a maximum of 30 students in a class, our classmates stay in two separate classrooms while having classes. Regarding the present situation, our school has implemented the enclosed management, which I think is the most effective way to protect our health and offers us a chance to focus our mind completely on study.
