Millions have also signed up to Twitter, the “micro-blogging” service that lets members circulate short text and picture messages about themselves.Baroness Greenfield said: “What concerns me is the banality of so m uch that goes out on Twitter.” Why should someone be interested in what someone else has had for breakfast? It reminds me of a small child saying: “Look at me Mummy, I'm doing this”, “Look at me Mummy I'm doing that”.“It's almost as if they're in some kind of identity crisis.” The academic suggested that some Facebook users feel the need to become “mini celebrities” who are watched and admired by others on a daily basis. They do things that are “Facebook worthy” because the only way they can define themsel ves is by people knowing about them.“It's almost as if people are living in a world that's not a real world, but a world where what counts is what people think of you or (if they) can click on you,” she said.“Think of the implications for society if peop le worry more about what other people think about them than what they think about themselves.”Her views were supported by Sue Palmer, a literacy expert and author, who said girls in particular believe they are “goods they must sell to other people” on Fac ebook.She said: “People used to have a portrait painted but now we can more or less design our own picture online.It's like being the star of your own reality TV show that you create and put out to the world.”1. People who often use Facebook and Twitter will _________.A. develop strong online friendship with other usersB. improve their ability to last their attention on thingsC. need non-verbal skills to communicate with each otherD. have a childlike desire for constant feedback on their lives2. The underlined word “banality” in the passage may mean _________.A.something that is dullB.something that is interestingC. something that is importantD.something that is serious3. The purpose of the passage is?A.to explain the identity crisis of Facebook and Twitter.B. to warn people not to be cheated on Facebook.C.to introduce the functions of Facebook and Twitter.D. to advise people to use less social networking.Roald Dahl - the author who entertained people with classics like Matilda, Charlie and the Chocolate Factory and James and the Giant Peach - would have been 100 years old this year. Roald Dahl is most famous for the books he wrote for children, but he also wrote novels and short stories for adults, screenplays, and non-fiction, too!Roald Dahl was born near Cardiff, in Wales in 1916. His parents were from Norway, and they named him after Roald Amundsen, the famous Norwegian explorer. Roald was sent off to boarding school when he was only nine years old. He was very homesick, and had a hard time obeying the strict teachers and the headmaster. In those days, teachers would sometimes hit their students with a cane (藤条)when they misbehaved. This naturally made a lot of children very afraid of their teachers! Later on, Roald integrated this fear and distrust of adults into many of his children's books.During World War II, Roald joined the Royal Air Force and flew missions over Africa, the Mediterranean, and the Middle East. At one point, his plane crashed in the Libyan Desert. He was temporarily blinded, and stranded in the middle of nowhere with a cracked skull and a broken nose. Fortunately, he was rescued, and within a few months had made a complete recovery. After his injuries forced him to leave the Air Force, Roald began writing. His first published piece was a magazine article about his plane crash. During the 1950s, he became an accomplished writer of short stories for adults. These stories usually featured mystery, suspense, and a twist ending.In 1961, Roald published James and the Giant Peach, which tells the story of a young boy who attempts to escape from his two nasty, abusive aunts. The boy finally gets away by sailing across the ocean inside a magical. giant peach and befriends the giant bugs that live inside it. James and the Giant Peach was prompted by the bedtime stories Roald would make up for his young daughters. He said that it was a challenge to keep them interested and attentive--- he had to make his stories funny, exciting, and original. In 1964, he wrote his most famous book--- Charlie and the Chocolate Factory, in which a poor boy wins a “golden ticket” to tour a mysterious world.4.Many of Roald Dahl’s children’s stories were inspired by .A.a vacation he took with his grandparentsB.his relationship with his parentsC.his time in the militaryD.his time away at boarding school5.What led Roald Dahl to write James and the Giant Peach?A.The bedtime stories he told his daughters.B.His lifelong love of peaches.C.The insects he found in his garden.D.The cruelty he experienced at the hands of his aunts.6.Which of these statements is an opinion about Roald Dahl?A.He published more than a dozen books for children.B.He was the greatest children's author of the 20th century.C.James and the Giant Peach was his first book for children.D.Several of his books were adapted into successful movies.It was New Year’s Night. An aged man was standing at a window. He raised his mournful eyes towards the deep blue sky, where the stars were floating like white lilies(百合) on the surface of a clear calm lake.When he cast them on the earth,where few more hopeless people than himself now moved towards their certain goal-the tomb. He had already passed sixty of the stages leading to it,and he had brought from his journey nothing but errors and regrets. Now his health was poor, his mind vacant and his heart sorrowful,and his old age short of comforts.The days of his youth appeared like dreams before him, and he recalled the serious moment when his father placed him at the entrance of the two roads—one leading to a peaceful, sunny place, covered with flowers, fruits and resounding with soft, sweet songs; the other leading to a deep, dark cave, which was endless, where poison flowed instead of water and where devils and poisonous snakes hissed(发出嘶嘶声) and crawled.He looked towards the sky and cried painfully,”Oh,youth,return!Oh,my father,place me once more at the entrance to life,and I’ll choose the better way!”But both his father and the days of his youth had passed away.He saw the lights flowing away in the darkness. These were the days of his wasted life; he saw a star fall from the sky and disappeared, and this was the symbol of himself. His regret,which was like a sharp arrow,struck deeply into his heart. Then he remembered his friends in his childhood. But they had made their way to success and were now honored and happy on this night.The clock in the high church tower struck and the sound made him remember his parents’ early love for him. They had taught him and prayed to God for his good. But he chose the wrong way. Withshame and grief he dared no longer to look towards that heaven where his father lived. His darkened eyes were full of tears, and he burst out a desperate cry: “Come back, my early days!Come back!”And his youth did return, for all this was only a dream ,which he had on New Year’s Night. He was still young though his faults were real; he had not yet entered the deep, dark cave, and he was still free to walk on the road which leads to the peaceful and sunny land.Those who still wander on the entrance of life, hesitating to choose the bright road, remember that when years are passed and your feet stumble (蹒跚) on the dark mountains, you will cry bitterly, but in vain: “Oh youth, return! Oh give me back my early days!”7.What does”them”in Paragraph1 refer to according to the passage?A.White lilies.B.The floating stars.C.The aged man’s eyesD.Hopeless people.8.Which of the following about the man is NOT true?A.In the dream,he was one of the most hopeless people approaching death.B.Though he did nothing wrong,the dream taught him a good lesson.C.He remembered his loving parents and joyful friends in his dream.D.His father once allowed him the freedom to choose the way of life9.Which of the following show the man’s feelings in his dream?①sad②sorrowful③peaceful④painful⑤angry⑥regretful⑦shameful⑧joyful⑨desperateA.①②③④⑥⑦B.②④⑥⑦⑧⑨C.①④⑤⑥⑦⑨D.①②④⑥⑦⑨10.Which of the following best shows the theme of this passage?A.It’s too late to regret when a bad choice is made.B.One false step can lead to a great error.C.It’s never too late for one to mend his ways.D.Hope for the best,but prepare for the worst.横线上填入一个最恰当的单词。

肇东一中2016-2017学年度高二下期中考试英语学科试题(2017.5)第一节:阅读理解(共20小题;每小题2分,满分40分)阅读下列四篇短文,从每小题后所给的A、B、C、D四个选项中,选出最佳选项,并在答题卡上将该选项涂黑。

AThe sun is shining when I get on No. 151 bus. We passengers sit jammed together in heavy clothes. No one speaks. That’s one of the unwri tten rules of Chicago commuting. Although we see the same faces every day, we prefer to hide behind our newspapers. The phenomenon is striking: people who sit so close together are using those thin sheets of newsprint to keep their distance.As the bus app roaches the Magnificent Mile, a voice suddenly rings out: “Attention! Attention!” Papers rattle (发出细小声). Necks crane (伸长). “This is your driver speaking.”We look at the back of the driver’s head. His voice has authority.“All of you put your papers down.”The papers come down, an inch at a time. The driver waits. The papers are folded and placed on our laps.“Now, turn and face the person next to you. Go ahead.”Amazingly, we all do it. Still, no one smiles.I face an older woman, her head wrapped tightly in a red scarf. I see her nearly every day. Our eyes meet. We wait, unblinking, for the next order from the driver.“Now, repeat after me…” It is a command, delivered in the tones of a drill sergeant (操练军士). “Good morning, neighbor!”Our voices are weak and timid. For many of us, these are the first words we have spoken today. But we say them at the same time, like schoolchildren, to the strangers beside us.We smile and can’t help it. We have said it; the barrier has been broken. Good morning, neighbor. It is not so hard after all. Some of us repeat it. Others shake hands. Many laugh.The bus driver says nothing more. He doesn’t need to. Not a single newspaper goes back up. I hear laughter, a warm sound I have never heard before on bus No. 151. This day is starting off better than most.1. On hearing the sudden utterance of “Attention!”, the passengers ___________.A. stopped reading and put down their newspapers immediatelyB. looked up from the newspapers to see who was speakingC. sat still without responseD. were frightened2. The underlined word “commuting” in Paragraph 1 most probably means ___________.A. daily traveling between home and workB. long-distance rideC. communication technologyD. behavior patterns3. Which of the following is true according to the passage?A. The passengers on the crowded bus are so absorbed in reading their newspapers that no one speaks.B. The passengers are physically close together but mentally they keep each other at a terrible distance.C. The passengers don’t follow the driver’s instruction at first.D. When the bus driver says nothing more, the passengers pick up and read their newspapers again.4. What would be the best title for the text?A. The Warmth of CommunicationB. The Exchange of InformationC. The Power of ObservationD. The Attitude to LonelinessBThe World Health Organization (WHO) said that processed meat may be carcipogenic(致癌). Do you still dare eat cancer-linked processed meat Here are some comments on the website.Bill (Australia) I’d rather live a short, pleasant life than a long, unhappy one, denying(拒绝给予) myself tasty food just because some experts say it’s not healthy. We should all en joy the one life we have ---if I had listened to every piece of health advice I would never go anywhere, eat anything or enjoy life in any way. So, I won’t change my habit. I am going to have bacon sandwich, glass of wine, burger, can of coke whenever I fell like it.Tim (America) Is meat really as bad as smoking: I don’t think so. According to the WHO 34,000 people die worldwide per year because they eat processed meat. In 2012, 8.2 million people died of cancer worldwide. That means if you eat a lot of processed meat you have a chance of being among the 0.41 percent of people dying of cancer because of processed meat. I’ll take the chance.Helen (Switzerland) The WHO doesn’t say that just one bite of meat causes cancer, it is rather saying that people should vary their diet. People who eat more meat often have other unhealthy habits. They usually eat fewer fruits and vegetables and they also often exercise less.Van (China) Perhaps this report will make people consider becoming vegetarians ( 素食者). So for your health, the environment and future generations, it is not difficult; it just needs a change of attitude. There is a vast variety of other delicious food available to enjoy.5 .What if Bill has to change his habit?A. He’ll feel unhappy.B. He’ll live a pleasant life.C. He’ll go on a diet.D. He’ll become a vegetarian.6 What does Tim think about eating processed meat?A. Too risky.B. Fairly safe.C. Popular worldwide.D. Very unhealthy.7 . What may be Hel en a response to WHO’s warning?A. Caring little about it.B. Eating whatever she likes.C. Varying the diet and doing exercise.D. Taking a diet without meat.8 .Who have the most similar viewpoints?A. Bill and Tim.B. Tim and Helen.C. Helen and Van.D. Bill and Van.CBefore I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn’t only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren’t jealous of him.In short, we don’t laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person’s emotions, he will certainly like it a lot.9.What did the author find out after studying psychology?A. Only good jokes make people laughB. Many factors lead to people laughing.C. Funny things can make people laughD. Laughter can make people healthy.10. Why did the audience laugh loud at the pedestrians?A. They played a trick on the pedestrians.B. The pedestrians behaved in a funny way.C. They could feel the pedestrians’ happiness.D. Their emotion was approved of by the show.11. What does the underlined wor d “belittling” probably mean?A. AnnoyB. BlameC. Look down onD. Make up toDHoverboards(电动滑板)were among the most popular Christmas gifts of 2015. They may have also been most dangerous gifts of 2015.A true hoverboard looks like a skateboard without wheels. To “hover” means to float in the air without moving much in any direction. The popularity of hoverboards began in the 1980s, with the “Back to the Future” movies. Characters in the second and thi rd films used hoverboards astransportation.This year’s popular hoverboards, however, do not actually hover. They have wheels. And? as it turns out, they are not easy to use.Adults and children around the world suffered hoverboard-related injuries over the weekend. Many posted pictures of the damage on social media. Twitter user David Douglas posted a photo of both him and a young girl with the broken arms they suffered on Christmas Day. And another user Erin Rafferty uploaded a video of her mother falling off a hoverboard, with the caption, “Who let mom on the hoverboard?”Falling is not the only risk with some hoverboards. They are also a fire risk. At one store in Texas, an employee tried to fix a hoverboard a customer brought in. The hoverboard then caught fire. Studies suggest that some hoverboard brands have defective batteries or plugs.Many major airlines worldwide have banned hoverboards because of the fire risk. But some passengers did not hear the news. Australian actor Russell Crowesaid on Monday about his disappointment that Virgin Australia Airlines did not permit his children to take their hoverboards on the plane.Major retailers (零售商)are also taking steps to improve the safety of the hoverboards they sell. Amazon in the United States now only sells hoverboards from brands that have submitted safety standard documents. The UK’s Amazon no longer sells hoverboards. It has also advised customers who bought unsafe brands of hoverboards to throw them away.12.What’s the problem with this year’s hov erboards?A. They don’t have wheels.B. They catch fire in the sun.C. They are difficult to handle.D.They can’t move in any direction.13.We can infer from the passage that ___________ .A.the number of hoverboard-related injuries is declining.B.hoverboards are still enjoying equal popularity as before.C.hoverboards are still sold on Amazon in the United States.D.passengers are forbidden to get on planes with hoverboards.14.The underlined word “defective” in the sixth paragraph probably means _____________ .A. faultyB. spareC. deadD. dry15.We can probably read this passage in a ___________ .A. newspaperB. textbookC. science fictionD. movie review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。

AThe Best Theatres of the Year“A Streetcar Named Desire”Maxine Peake, following outstanding performances in “Hamlet” and “The Skriker”, now plays Blanche DuBois. It will be fascinating to see whether Peake plays Blanche as a shape of the poetic spirit rather than a crazy southern beauty. With Sarah Frankcom directing and Ben Batt as Stanley Kowalski, the play must be good.September to 15 October, Royal Exchange, ManchesterBox office: 0161-8339833“The Gaul”Some time on the night of 8 February 1974, fisherman FV Gaul disappeared off the coast of Norway. For the families of the 36 men on board, waiting for news was a hard time. Stories came up. Even when he was discovered on the seabed, many still felt there were questions that remained unanswered. Mark Babych directs Janet Plater’s play.6-29 October, Hull TruckBox office: 01482323638“The Red Barn”David Hare’s new play is based on “La Main”, a thriller by the great Georges Simenon. The setting is Connecticut 1969, and the story is about two couples who, on their way back from a party, try to go through the snow. The play is directed by Robert Icke, and Mark Strong and Hope Davis are leading actors.6-20 October Lyttelton, LondonBox office: 020-********“The Cheviot, the Stag and the Black Oil”John McGrath’s play about the exploitation (开发) of the Scottish Highlands has been described as the most important show in the history of the Scottish theatre.

What can we infer about Maxine Peake?A. She is a famous director.B. She acted well in ”Hamlet”.C. She is a friend of Blanche DuBois.D. She enjoys poems much.2. What happened to FV Gaul in the play?A. He was caught in the snow.B. He came back to life after he died.C. He disappeared and died.D. He explored the Scottish Highlands.3. The director of “The red Barn” is _____.A. David HareB.

About the plays mentioned in the passage, we can know they _____.A. are all thrillersB. are directed by the same personC. would be on in autumnD. would be on at the same theatreBBritish shoppers buy 2.15 million tons of clothing and shoes per year, yet UK people have about £ 30 billon worth of unused clothing at the back of the wardrobe (⾐橱) . But new technology could see the end of tat (粗⿇布) with the clothes themselves reminding the owners of their existence.“Smart clothes” could help us clear out our wardrobes by sending messages or tweeting (推⽂) to us if they haven’t been worn for a good while. If these messages are ignored, the clothes will get in touch with a clothing charity and ask to be reused, with an organization automatically sending out donation in order. They could also be programmed for a public sale where they are sold to whoever offers the highest price on eBay.Experts at Birmingham, City University are developing the “connected wardrobe”to encourage more suitable clothes consumption (消费). The new kind of wardrobe sees clothes tagged, using washable contactless technology.Mark Brill, senior lecturer at the university, said, “Think of the surprise when an owner suddenly receives bids (出价) for items that they didn’t know in their wardrobe. The ‘connected wardrobe’is a practical pleasant idea to encourage people to think about their clothing consumption. Finally, I hope it will encourage more proper fashion consumption. Perhaps we can even move away from the idea of the ownership of clothing. When we’ve worn them enough, the items will pass themselves on to their next keeper.”It follows in the footsteps of the “Internet of things”—an idea that sees ordinary household items connecting to the Internet in order to share information. Now, the “Internet of Clothes” will make sure that neglected clothes will tweet and text the owners,“asking” to be worn depending on the weather and frequency of wear. Clothes will keep track of other information, such as who owned them before, as well as how much they originally cost, who made them and how much the worker was paid for them.5. What does the author say about the “smart clothes”?A. They may be recycled if long forgotten.B. They have gotten popularity.C. They give warnings if worn out.D. They may be donated on eBay.6. What is suggested in the last paragraph?A. The Internet is a place to share items.B. Weather affects the connected wardrobe.C. Household items can be a source of information.D. Clothes are sold online at a low price.7. The underlined word “neglected”in the last paragraph means “_____”.A. changeableB. unforgettableC. recycledD. unnoticed8. What’s the passage mainly about?A. The future of clothes consumption.B. The new technology about clothes.C. Common things sold on the Internet.D. Recycled wardrobes on the market.CCold weather during winter months may keep many people from running in the open air. However, a new study shows that the drop in temperature is a good reason to run. Researchers say running in cold weather helps improve one’s performance. Many people say running in winter can be difficult. Two reasons are the low temperatures and cold winds. Yet many runners might find it easier than running in hot weather. That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body’s dehydration (脱⽔) levels are lower than those in warmer conditions. The body needs less water on a cold day than in warm weather.This information comes from sports scientist John Brewer at St Mary’s University in London. He and other researchers put a group of people into a room they called an “environmental Chamber”. They then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. The team recorded biological measurements of the runners.Brewer says every movement runners make produces heat. One way in which people lose heat is by sweating (流汗). The body also loses heat by transporting the blood to the surface of the skin, which puts more pressure on the heart in summer because it’s much harder to lose heat in the warm environment. However, the body doesn’t have to work as hard to transport blood to the skin’s surface in cold conditions. That means running in cooler temperatures requires less energy.Several websites note that the most important thing for people who run in cold conditions is to wear the right clothing. Wear shoes that will keep you from falling. Keeping as dry as possibleis most important when exercising in low temperatures. And wear more than one layer (层) of clothing to keep sweat away from your skin. So don’t let winter keep you indoors. Simply get ready for the low temperatures and start running.9. What were the test subjects required to do in the “environmental chamber”?A. Stay in the room in the hot and cold conditions.B. Run more than 10,000 meters in the warm environment.C. Run 10,000 meters under summer and winter weather conditions.D. Stay in the room for a long time in the cold environment.10. Running in cooler temperatures requires less energy because _____.A. it prevents runners producing sweatB. it’s much harder for the body to lose heatC. it’s easier for the runners to breathe fresh airD. it’s easier for the body to send blood to the skin’s surface11. Which of the following are proper ways to run in cold conditions?①Wearing as dryly as possible.②Wearing only one layer of clothing.③Wearing shoes that will prevent falling.A.①②B.②③C.①③D.①②③12. What is the author’s purpose in writing the passage?A. To show his love of running in cold weather.B. To persuade people to stay indoors in winter.C. To give some advice on running in cold weather.D. To encourage people to run in cold weather.DWe had about half an hour until the bus would arrive to take us to the airport. I wasn’t worried about my daughter. At ten years old, she could easily entertain herself. But what was my four-year-old son going to do for the next 30 minutes?Half an hour could seem like a long time for a pre-school child. He began playing with his toy car. Then he noticed a boy similar in age. Actually, they noticed each other. Slowly, theybegan to interact (互动). At first, they shared smiles, which soon led to sharing toys. And before I knew it, they were running and playing in the hotel lobby.I realized that the scene described above was not uncommon. However, there was one thing that I have to mention: The boys did not share a common language. However, this little thing didn’t seem to stop them from their fun in the least. They were two little boys who had just met, and they were having more fun than anyone else in the lobby. In fact, I believed they would have played together all day if we had let them.Classrooms around the world are becoming more and more diverse (多种多样的). And that’s a good thing. But with this diversity comes a responsibility to our students. We must provide ways in which they can interact and feel comfortable, despite the language that they do or don’t speak. We must allow students who share the same interests to spend time together—even when they don’t share the same language. By doing this, we immediately place them in their comfort zone. When they work within their strengths, students’ confidence grows.Furthermore, as walls come down, students are more likely to welcome and work together with those whom they may not have noticed before.13. From the first paragraph, we can infer that_____.A. the author arrived at the airport half an hour earlier.B. the author was worried about his son.C. the author’s son could easily entertain himself.D. the author’s daughter was worried about her little brother.14. What happened to the two boys without sharing the same language?A. They played together happily.B. They learned from each other.C. They had difficulty in communicating.D. They made noises in the hotel lobby.15. According to the passage, students who_____.A. share the same language would be friends.B. come from the same place can communicate well.C. have the same interests should spend time together.D. come from different families have different habits.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。

This is the undercurrent (潜流) of conversation at Einstein memorial meetings throughout the year. A new Einstein will appear, scientists say. But it may take a long time. After all, more than 200 years separated Einstein from Isaac Newton.Many physicists say the next Einstein hasn't been born yet, or is a baby now. That's because the search for a unified theory that would explain all the forces of nature has pushed current mathematics to its limits. New math must be created after the problem can be solved.But researchers say there are many other factors working against another Einstein appearing anytime soon. For one thing, physics is a much different field today. In Einstein's day, there were a few thousand physicists worldwide, and the theorists who could argue with Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One key aspect of Einstein's training that-is little noticed is the years of philosophy he read as a teenager-Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently about space and time and it wasn't long before he became a philosopher himself.And Einstein was a clever musician. The interplay between music and math is well-known. Einstein would play his violin hard as a way to think through a knotty physics problem.Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills. Those who stay in science don't work alone and they sometimes do experiment together which takes years.It's hard to imagine a renegade (背叛者) like Einstein standing it. "Maybe there is an Einstein out there today," said Columbia University physicist Brian Greene,"but it would be a lot harder for him to be heard."21.According to the second paragraph, the next Einstein will _____.A. have to create new mathB. create a unified theoryC. have to be born nowD. push math to its limits22. The underlined words "knotty" in the fourth paragraph means _____.A. easyB. interestingC. strangeD. difficult23. Which of the following will be useful for the next Einstein to be born?A. There will be music around.B. There will be no problems to solve.C. There will be suitable philosophy to study.第二页D. There are only a few physicists.24. Which of the following can be the best title for this passage?A. Wait for the Next Coming EinsteinB. Environment Needed for the Birth for the Next EinsteinC. Philosophy---- The Next Einstein WantsD. Einstein and the Next EinsteinBThere are usually both parents and two children in a typical British family. In most British families both parents work. Very young children go to nursery schools or stay at home with a childminder. Old people usually live in their own homes or a nursing home if they cannot look after themselves. British parents try to spend their free time with their children going to the cinema, museums or parks. During the week they usually have dinner together.Americans often move house from city to city or from state to state. For this reason American families live far away from their relatives. However, they keep in touch with each other by telephone or letter. During the holidays or at celebrations like Thanksgiving, families often visit each other. A typical American family is the same as a British family. Both parents work. Like British families, American parents try to spend time with their children at weekends. They often visit museums. They also go to the cinema or to the park.There are many different kinds of houses in the UK. More than half of the people in the UK own their houses. Other people rent houses or flats. British people like to feel comfortable and safe in their homes. They like to make their homes and gardens look attractive. Perhaps that’s why gardening i s one of their most popular pastimes.The buildings in American cities are similar to those in British cities. There are tall tower blocks, skyscrapers(摩天楼),houses and large brick buildings. In the suburbs, however, the houses are very different. A lot of Americans live in wooden houses with front and back gardens. Two thirds of Americans own their houses. Other Americans rent houses, apartments or rooms. Americans are usually very house-proud and take good care of their homes.25. Many couples today in Britain ______A. usually have two childrenB. have difficulty in finding good jobsC. don’t like living with their parentsD. have to work hard to support their children26. Americans usually keep in touch with their relatives by telephone or letter because ______.A. they live too far awayB. they don’t like travelingC. they are too lazy to pay a visitD. they are too busy to meet each other27. The underlined word “pastimes” in Paragraph 3 refers to something you enjoy doing in your ______.第三页A. housework timeB. hard timeC. spare timeD. pleasant time28. We can be sure that ______.A. Americans like children betterB. more Americans live in the suburbsC. Americans think more highly of their familiesD. Americans like living in wooden houses with front and back gardensin the suburbs.CLondon is a sporty city. Every year 30 ,000 people run the London Marathon and manage to raise $ 30 million for charity. Thousands of people line the streets to watch the race. The marathon might not be everyone's cup of tea―so read on to learn about different ways you can get fit in London.If you are not sure what you'd like to do, check out these ideas below :• Football Whether you want to join a local team or simply start playing in your back garden or a park, football is one of the easiest and cheapest sports you could take up. Find your nearest community club.• Cricket (板球) Like football, all you need is some space and basic equipment to start playing cricket. If you start getting serious about the game, there are lots of opportunities for you to play it in London. Search for a club near you.• Tennis If you are fed up with watching English players lose at Wimbledon, try your hand at tennis and maybe one day you'll make the country proud. Lots of the London parks have tennis courts(球场).• Gymnastics If you want to try your hand at gymnastics, there are over 70 different clubs in London that will help you learn more. To find your nearest club, call the London Gymnastics Federation on (0)20 8529 1142.• Rugby(橄榄球) If England's great achievement in the World Cup arouses your interest, find a club near you in London. Although lots of people think of rugby as something played more in the north of the country, it's quite easy to play the game in London too.29. The underlined sentence in the first paragraph probably means that English people don't___________.A. drink tea before running the marathonB. plant tea along the marathon race pathC. all like the marathon raceD. all like drinking tea30. We can learn from the passage that______.A. people in London don't like rugbyB. the country is proud of each tennis playerC. 30 million people take part in the London MarathonD. there are tennis competitions in Wimbledon31. In which of the sports does the passage mention that English people often lose?A. Football.B. Cricket.C. Tennis.D. Rugby.DWalk into the small Australian town of Coober Pedy on any given day, and you will第四页get the strange feeling of an abandoned ghost town. So why even call it a town? Because that’s exactly what it is, complete with 4,000 plus residents of 48 nationalities, all of whom live underground!Located about 846 km north of Adelaide, Coober Pedy was built in 1915, following the discovery of opal (蛋白石). As people from across the country and world flocked to mine the precious stone, they realized that while working under the ground was easy, living above it was not, thanks to the extreme temperatures.They therefore did what humans do best when faced with a situation they cannot change—adaptation! In this case, it meant living underground, by changing old mines into homes and building the world’s first and most likely, the only underground town. As years have gone by, the homes have become bigger and more sophisticated (复杂巧妙的). There are now also several hotels and inns (旅馆)to accommodate the tourists that flock in from all over the world, to see this unusual town. And while the structures may be located underground, they are as good as those that lie above. Not only do the underground town take full advantage of the beautiful red rock, but they also feature all the modern amenities(便利设施) like walk-in closets, modern kitchens and televisions. And if that is not enough, the town also has gift shops selling opal jewelry, a couple of museums and even a church! For those that need some physical activities, the town offers a golf course.Besides being the opal capital of the world and a popular tourist destination, Coober Pedy is also a favorite among filmmakers and has been featured in movies such as Pitch Black, Red Planet and Opal Dream.32. People first built Coober Pedy to _______.A. avoid the hot weatherB. make full use of roomC. protect themselves from the animal danger aboveD. take advantage of the local materials33. According to the fourth paragraph, Coober Pedy ______.A. has very simple structuresB. has become a great tourist attractionC. provides more amenities than a modern hotelD. only allows people to live a simple life34. What do people probably feel when staying in Coober Pedy?A. Disappointed.B. FrightenedC. ComfortableD. Curious.35. What is the text mainly about?A. A ghost town in Australia.B. Australia’s exciting underground town—Coober Pedy.C. The structure of an underground town.D. The attraction of Coober Pedy to filmmakers.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。
