ACleverness is a gift while kindness is a choice. Gifts are easy––they’r e given after all. Choices can be hard.––Jeff BezosI got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but finally, I decided I had to give it a shot. I didn’t think I’d regret trying and failing. And I suspected I would always be haunted by a decision to not try at all.After much consideration, I t ook the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.21. What inspired the author with the idea of building an online bookstore?A. His dream of being an inventor.B. The support of his wife.C. The greatly increasing usage of the Internet.D. Millions of exciting titles.22. We can know from the passage that _______.A. the boss thought the idea was suitable for the authorB. the author might not regret if he failed the ideaC. the author wanted someone else to try the ideaD. the author might go back to his boss if he failed23. Which of the following would be the best title for the passage?A. Cleverness and KindnessB. The Starting of AmazonC. Following My PassionD. We Are What We ChooseBThe Cat in the Hat takes place on a cold, wet day with two kids awaiting their mother’s return. Instead of their mother, a strange cat enters the house. He begins balancing a fish bowl on the tip of his umbrella while balancing himself on a beach ball! The two kids and their pet fish worry and worry. But readers around the world laughed and laughed over the Cat and the Hat.Theodore Seuss Geisel, known to fans as Dr. Seuss, wrote the book. It was first published in 1957. Geisel liked to have fun and make people laugh, but he had a serious reason for writing the book. In 1954, a Life magazine article argued that kids couldn’t read because the books used to teach them how to read were too boring. John Hersey, the Pulitzer-prize winning author of the article, suggested Geisel write a story that “first graders wouldn’t be able to put down”.To write the book, Geisel had to have a good knowledge of a beginning reader’s word list. Geisel says that he came up with the title by looking for the first two words on the list that rhymed (押韵). And so The Cat in the Hat was born! But it wasn’t an easy book to write. It took Geisel one and a half years to complete.To celebrate The Cat in the Hat’s birthday, Random House, the book’s publisher, created Project 236. The number 236 represents the number of words Geisel used to write the book. As a part of Project 236, there will be a nationwide read-aloud of The Cat in the Hat at 236 on March 2, Dr. Seuss’s birthday.24. According to Paragraph 1, we know that The Cat in the Hat ______.A. tells stories between two kids and their pet fishB. was written for children left alone at homeC. entertained children around the worldD. was written in winter25. What is Dr. Seuss’s purpose in writing The Cat in the Hat?A. To improve children’s reading.B. To support John Hersey.C. To develop educational system.D. To make readers laugh.26. It can be inferred that John Hersey ______.A. thought his article was too difficult for first graders to readB. was dissatisfied with children’s readings of that timeC. won the Pulitzer-prize because of the bookD. was the editor of the magazine Life27. Why did Random House create Project 236?A. To celebrate Dr. Seuss’s birthday.B. In support of the nationwide read-loud.C. To make more readers get to know Dr. Seuss.D. In honour of the birth of The Cat in the Hat.CIn Africa, Christmas day begins with groups of carolers (欢唱颂歌的人) walking to and fro through the village, along the roadway, by the houses of the churchmen, singing the lovely carols known the world around. Often people may be awakened by a group of carolers beginning to gather at the church. They return home to make final preparation as to the clothes one must wear and also as to his offering for the Christmas service. The most important part of their Christmas service is the love offering. This is the gift in honor of Jesus. At about 8 or 9 o’clock, everyone makes their way to the celebration of the birthday of Jesus. Everyone who attends the service goes forward to lay down their gift upon the raised platform near the Communion table. Not one person will attend the service without giving a gift.Christmas in South Africa is a summer holiday. There is no snow, but it has many flowers, many beautiful varieties of wild flowers being in their full pride.In Ghana, most churches announce the coming of Christmas by decorating the church and homes beginning with the first week in Advent, four weeks before Christmas. This season happens to be the cocoa harvest time, so it is a time of wealth. Everyone returns home from wherever they might be, such as farms or mines.In Africa, it is the traditional dinner of turkey, roast beef, mince pies, suckling pig, yellow rice with raisins, vegetables, and plum pudding, or crackers. In the afternoon, families go out into the country and usually there are games or bathing in the warm sunshine, and then home in the cool of the evening. Boxing Day is also a public holiday of real relaxation usually spent in the open air, which falls on December 26.28.

The Homeless World Cup exists to end this, so we all have a home, a basic human need.The Homeless World Cup is an annual, international football tournament(联赛), uniting teams of people who are homeless to take a once in a lifetime opportunity to represent their country and change their lives forever. It has inspired and supported over 50 grass roots (基层的) football projects around the world working with homeless people throughout the year.The first tournament took place in Graz 2003 uniting 17 national teams. At the 5th Homeless World Cup in Copenhagen in 2004, 48 nations, 500 players were united for a once in a lifetime opportunity to represent their country. 25,000 players were involved in pre-tournament training and trials around the world.The Homeless World Cup is full of players with courage, spirit and determination. Research shows that 73% of players change their lives for the better after the international tournament by coming off drugs and alcohol, moving into jobs, education, homes, training, reuniting with families and even going on to become players and coaches for professional or semi-professional football teams. David Duke (Scotland) played in 2004, came off alcohol, passed his coaching qualifications (资格). He became assistant coach for Scotland 2005, coach in 2006 and now owns his own home. The best goal scorer in 2004 Yevgen Adamenko (Ukraine) went on to play in a professional club in Ukraine.The Homeless World Cup supporters include Nike, UN, Manchester United, Real Madrid and international footballers Didier Drogba and Rio Ferdinand.32.

2019-2020学年辽宁省实验中学高三英语期中考试试卷及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AYou have to praise the smoothness（顺畅）of ants on the move. No matter how many of them are going toward a place, there's never a hold-up. A new research paper shows how ants keep traffic flowing by changing their behavior to meet changing conditions.For their experiments, researchers from the University of Toulouse focused on Argentine ants, animals that often move from colony（群落）to colony depending on where the food is. Making use of Argentine ants' talent for fast travel, the researchers built bridges connecting their colonies. The bridges were different in width from a fifth to three-quarters of an inch. The colonies, too, were of different sizes, ranging from 400 to more than 25,000 ants.Then the researchers sat back andmonitoredthe traffic. To their surprise, even when those narrower bridges were full of ants, there were no "traffic accidents". "When the number of ants on the bridge increased, ants seemed to be able to understand the situation and adjusted（调整）their speed accordingly to avoid making the traffic flow stop. "the authors note. "Moreover, ants avoided entering a busy road and made sure that the bridge was never too packed to cross.”The lesson for humans? The traffic problem may lie in our inability to adjust our driving habits for the good of the whole. Driving is fun when there are few cars on the road. Then the traffic moves very slowly. And yet, some impatient driver still acts like he's alone on the road.The research suggests that projects, like the ever-widening of highways, may never free us from traffic jams. As long as we drive along with our own habits, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may actually be a good thing. It leaves less room for individual choice and forces us to take a page from the driving book of ants.1. What is Paragraph 2 mainly about?A. The results of the experiments.B. The purpose of the experimentsC. The preparation of the experiments.D. The requirements of the experiments2. What does the underlined word "monitor" in paragraph 3 probably mean?A. watch and check.B. seek and improveC. design and planD. discuss and practise3. What is the best title for the text?A. Is widening highways a solution?B. Why don't ants need traffic lights?C. Can we learn safe driving from ants?D. What can ants teach us about traffic jams?BWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. 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 GivingCLarry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children of his age were not even allowed to dive.After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them .Fortunately for him, a man offered to take him around the different spots for rry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken.The diving spots afforded such a wide range of fish and sea creatures that Larry sawmore than thirty varieties of creatures.Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.8. In what way was this expedition different for Larry?A. His daughter had grown up.B. He had become a famous diver.C. His father would dive with him.D. His daughter would dive with him.9. What can be inferred from Paragraph 2?A. Larry had some special right.B. Larry liked the rented diving suits.C. Divers had to buy diving equipment.D. Ten-year-old children were permitted to dive.10. What can be learned from the underlined sentence?A. Larry didn’t wear a watch.B. Larry was not good at math.C. Larry had a poor memory.D. Larry enjoyed the adventure.11. What did Larry expect his daughter to do?A. Become a successful diver.B. Make a good diving guide.C. Take a lot of photo underwater.D. Have longer hours of training.DIn recent years, with the development of technology, it is common to see robots into our homes in the form of toys and vacuums (吸尘器) without question. Children’s toys that rely on robotics for both entertainment and education are becoming more popular and more easily accessible. Robot vacuums, too, are so popular that the Roomba has even earned itself a name in popular television.A selection of other household wares can be purchased and owned for a reasonable cost, but they all look and perform like vacuums. Our domestic helpers are currently designed to vacuuming, mopping, sweeping and mowing.Of course the best known of these is the Roomba, but there is actually some competition amongst the autonomous vacuum manufacturers. Roomba, made by iRobot, now comes in several designs and has been through many versions of improvements. The basic model is just about $400, but there’s a more attractive version, complete with a wireless command center to control the robot from anywhere in the home. Samsung also has avacuum, called the Smart Tango, which makes increased improvements on the Roomba by including brushes for cleaning corners. It’s possible that some of the less well-known vacuums might be even more exciting, like the Neato Robotics XV that takes on a square shape to better clean corners. Incremental (增值的) improvements are what drive the home robot industry.Now that domestic robots are becoming more popular, the near future should be exciting. If we are going to welcome robots into our lives and our homes, we should expect them to work for it, and work hard. It’s the dawn of the robot revolution, whether we like it or not, and it would be great to see that technology put to use in more innovative(创新的) ways.12. What does Roomba in the passage mean?A. A man’s name who has bought a domestic robot.B. A name of a big company who makes robots.C. A type of vacuum whose name is Roomba.D. A place where people can buy proper robots.13. The Smart Tango is different from other types in that ________.A. it has a wireless command centerB. it has brushes for cleaning cornersC. it is more famous and excitingD. it is driven without electricity14. What can we infer according to the last paragraph?A. Domestic robots will free us from housework.B. Domestic robots will become cheaper and cheaper.C. Domestic robots have brought environmental revolution.D. Domestic robots takes the lead in science and technology.15. What does the author intend to tell in the passage?A. Domestic robots are closely related to our daily life.B. It is interesting to see domestic robots at home.C. Domestic robots are too expensive for most people.D. It is convenient to buy a domestic robot.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。

Something wonderful, and with substance! 51 , I just want people to see me there in that casket (棺) with afork in my hand and I want them to wonder ‘What’s with the fork?

But he also knew that the woman had a 54 grasp of heaven than he did.At the funeral people were walking by the woman’s casket and they saw the pretty dress she was wearing and her favorite Bible and the fork 55 in her right hand.

Not only that, your memory and your immune system（免疫系统）will improve from eating fat. It is a very bad idea to remove fat completely from your diet. "Good" fats are quite necessary. These good fats come from things like vegetable oil, cold-water fish, etc. Eating the right kind of fat and avoiding the wrong kind is the most important part.1,000 rats in a study were fed a diet high in saturated（饱和的）fats, the kind in milk, cheese and red meat. Part way through, 500 of the rats had omega-3 fatty acids（不饱和脂肪酸）added to their diet. Not replaced, but added. "All of them lost weight and their heart problems got better." They were eating double the fat." This is why we need to know the value of fat and how Americans have got it all wrong for tens of years. Fat is amazing!We need fats to keep our body not only healthy but also active. When you cut too much fat out of your diet or eat the wrong fats, something bad will happen to your body.The best fats are omega 3 fatty acids, coming from vegetable oil and oil from cold-water fish. Saturated fats like those in cheese, beef and chicken and milk should play smaller roles in our diet. Meat fats should be avoided, along with oils in things like butter and snack foods. Old oils of any kind are also bad for you.56. What is the main idea of this passage?A. It tells the readers about the value of fat.B. We should cut fat in our diet.C. Eating fat food is good for us.D. Do's and don'ts in our diet.57. The study in Paragraph 2 showed that ______.A. the more fat you have in your diet, the worse it isB. omega-3 fats are not good for healthC. not all fat is bad for healthD. saturated fats are very good for health58. From this passage, we learn that _____.A. Americans haven't had fat for tens of yearsB. the right kind of fat can help us to keep healthyC. we should have a lot of fat in our diet to be healthyD. fat in our food has no relation with the fat in our body59. According to the passage, which of the following is the best for our health?A. Butter.B. Chicken.C. Beef.D. Cold-water fish.BIt would be pleasant to believe that all young girls in the past got married for romantic reasons; but the fact is that many of them regarded marriage as their only chance to gain independence from their parents, to have a provider, or to be assured of a good place in society. A couple of generations ago, an old maid of twenty-five did not have much to look forward to, she was more or less fated to remain with her parents or to live in some relative’s home where she would help with the chores and the children. Not so any more. In the first place, women remain young much longer than they used to, and an unmarried woman of twenty-eight or thirty does not feel that her life is over. Besides, since she is probably working and supporting herself, she is free to marry only when and if she cho oses. As a result, today’s women tend (倾向) to marry later in life. They have fewer children-or none at all- if they prefer to devote themselves to their profession. The result is a decline in the birthrate.The new role that women have developed for themselves has changed family life. Children are raised differently; they spend more time with adults who are not their parents: baby sitters, day-care center personnel, relatives, or neighbors. Whether they gain or lose in the process is a hotly debated question. Some child experts believe that young children must spend all their time with their mother if they are to grow sound in body and mind. Others think that children get more from a mother who spends with them “quality time” (a time of fun and relaxation set aside for them)rather than hours of forced and unhappy baby sitting. And many child psychologists point out that children kept in day-care centers every day are brighter than those raised at home. No matter what it is, one thing aboutchild raising to be certain of is that the longer the child is with the mother, the better.60. It can be concluded from the passage that______.A. women today have developed a new role in family lifeB. the birthrate is declining as a result of women’s pursuit(追求) of careersC. women have always been dependent on their parents even after marriageD. children must spend all their time with their mother if they are to grow sound61. The change in women’s attitude towards marriage results in all of the following EXCEPT______.A. more and more women quit(leave) jobs to take care of their children at homeB. women today tend to marry later than they didC. women have less time to raise childrenD. more and more families remain childlessCOne evening after dinner, Mr. and Mrs. T isich called a family meeting. “We’ve had to make a difficult decision,” Mr. Tisich announced. “You see, your mother has been offered a post as co-director of a television station in Chicago. Unfortunately, the station is not here. After thinking long and hard about it, we’ve concluded that the right decision is to move to Chicago.”Marc looked shocked, while his sister Rachel breathlessly started asking when they’d be moving. “It’s surprising, but exciting!” she said. Marc simply said, “We can’t go- I can’t leave all my friends. I’d rather stay here and live with Tommy Lyons!”The Tisichs hoped that by the time they moved in August, Marc would grow more accustomed to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings.When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyons’s house, but Mrs. Lyons said she hadn’t seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly.What they didn’t know was that Marc had started walking over to Tommy’s house, with a faint idea of hiding in the Lyons’s attic(阁楼) for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood; the fence that he and his mother painted, the tree that he and his sister used to climb, the park where he and his father often took evening walks together. How much would these mean without his family, who make them special in the fi rst place? Marc didn’t take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons(纸板箱) the right size to hold his record collection.64. The conflict in this story was caused by______.A. Marc an d Rachel’s different tempersB. a quarrel between Tommy Lyons and MarcC. Marc’s disagreement with his parents about their moveD. Mr. and Mrs. Tisich’s remark of Marc’s irresponsibility65. Marc and Rachel’s reactions to the move were similar in the way t hat both were______.A. surprisedB. angry and upsetC. anxious for more detailsD. worried about packing66. The reason for Marc’s going home was that______.A. he did not want to be left behindB. he realized his family was essential to himC. he hoped to reach an agreement with his parentsD. he wished to be a more responsible person67. What would most likely happen next?A. Marc would bring his records over to the Lyons’s house.B. Mr. and Mrs. Tisich would call the police.C. Marc would join his family for house moving.D. Mr. and Mrs. Tisich would start searching for MarcD68.What can you do if you like to go on holidays with pets?A. Choose the holiday in Devon.B. Go to the Snowdonia Cantre.C. Join the World Sen Trip of 2008.D. Visit Acapulco and Hawaii.第二节(共5小题；每小题2分，满分l0分)The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.But just as in face to face communication, there are some rules of behavior that should be followed when on line. 71 Imagine how you’d feel if you were in the other person’s shoes.For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” If the answer is no, rewrite and reread. 72If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 73 If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.___74 Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long ans wer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else. 75 At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.A. It’s natural that there some people who speak rudely or make mistakes online.B. Repeat the process till you feel sure that you’d feel comfort able saying the words to the person’s face.C. Everyone was new to the network once.D. The basic rule is simple: treat others in the same way you would want to be treated.E. When you send short messages to a person online, you must say something beautiful to hear.F. You should either ignore the person, or use your chat software to block their messages.G. If you do decide to tell someone about a mistake, point it out politely.第四部分写作 (共两节，满分35分)（请将主观题答案写在答题纸上）第一节短文改错(共10小题；每小题l分，满分l0分)文中共有l0处语言错误，每处错误仅涉及一个单词的增加、删除或修改。
