It was Groundhog Day．A winter storm had hit overnight too．I tried to open my backdoor only to find six inches of wet, heavy snow piled up against it．I knew I had quite a job of shoveling out ahead of me, so I reached over to grab my snow shovel．It looked a lot more ready to work than I did．I sighed and pulled on my boots, gloves, and heavy coat． The wind chill was below zero and cut into my face as I slowly shoveled off my deck．After that I stayed my way over to my daughter’s house shoveling the path as I walked．It took a while to get her driveway clear and I knew I still had a lot to do．Next came the paths down the hill to my own cars covered in snow．I had grabbed the broom to sweep them off as well．I winced when the breeze blew the swept snow back into my face．Then I started to shovel out my driveways．My back was aching as I worked．I wished I could be building a snowman instead of shoveling．Winter sure had seemed a lot more fun when I was a boy． When I was done I examined my work．It didn’t look half bad．I smiled and looked at thewoods covered in white．They were such a special sight．I leaned on my shovel and took it all in．Then I started up the hill with the snow shovel in one hand and the broom in the other．Suddenly, an urge came over me and I dropped them both．I spread my arms, fed back into the blanket of white and happily moved my arms and legs to make an angel in the snow．As you go through the seasons of this life take joy in your work．Take joy in your life．Remember that the course of your days rests in your own hands．（1）What’s the theme of the text？________A.Enjoy winter work．B.Take things seriously．C.Take joy in your life．D.Fight against cold．（2）Which is the correct order of what the author shoveled？________A.his deck﹣his daughter’s driveway﹣his cars﹣his driveway．B.his cars﹣his deck﹣his daughter’s driveway﹣his driveway．C.his daughter’s driveway﹣his deck﹣his driveway﹣his cars．D.his driveway﹣his daughter’s driveway﹣his cars﹣his deck．（3）What can we conclude about the author from Paragraph 3？________A.He was not satisfied with his work．B.He was absorbed in the snow sight．C.He was fond of making snowmen．D.He was in low spirits after work．【答案】CAB【考点】阅读理解综合【解析】本文是一篇历史文化类阅读，文章主要介绍了土拨鼠日．一场暴风雪也在一夜之间袭来．我试着打开我的后门，却发现有6英寸厚的湿雪堆积在上面．我伸手去拿雪铲，它看起来比我更愿意工作．我叹了口气，穿上靴子、手套和厚外套．【解答】（1）C．细节理解题．根据"As you go through the seasons of this life take joy in your work．Take joy in your life．Remember that the course of your days rests in your own hands．’可知课文的主题是在生活中享受快乐．故选C．（2）A．推理判断题．根据"The wind chill was below zero and cut into my face as I slowly shoveled off my deck．After that I stayed my way over to my daughter’s house shoveling the path as I walked．It took a while to get her driveway clear and I knew I still had a lot to do’可知作者铲的正确顺序是甲板、他女儿的路、他的车、他的车道．故选A．（3）B．推理判断题．根据"Suddenly，an urge came over me and I dropped them both．I spread my arms，fed back into the blanket of white and happily moved my arms and legs to make an angel in the snow．’可知作者被雪景吸引住了．故选B．3.If you’re a book lover, you may have a pile of books at your bedside, or a bookshelf in your room with a “to read” sign on it. Yet you can’t stop yourself from adding books to the pile. This can lead to feelings of guilt over your new purchases. But I’m he re to tell you to stop worrying.What you have is an antilibrary, and it’s a very good thing. The term comes from writer Umberto Eco. He is the owner of a large personal library. He separates visitors into two groups: those who react by saying “Wow! What a library you have! How many of these books have you read?” and the others who hold the point that a private library is not something to show off but a research tool. Read books are far less valuable than unread ones. Indeed, the more you know, the more unread books you will have. Let us call this collection an antilibrary.If you think you already know everything about a subject, you’re cutting yourself off from a stream of information. So a growing library of books you haven’t read means you’re consistently curious about the unknown. And that attitude provides the foundation for a lifelong love of learning.So don’t feel guilty about your unread books. Those books will be there for you when you do need them, and as you build your library of read and unread books, you can start using it as you are using a bigger library. Certain books may become references. Or you may find that a book you bought five years ago has special relevance today. Letting the role of books evolve in your life is a healthy sign of curi osity. That’s good for you and good for the world around you.（1）What does the underlined word “antilibrary” in Paragraph 2 refer to?A.Feelings of guilt over buying new books.B.A pile of books on the bookshelf.C.The collection of unread books.D.A large personal library.（2）According to the author, more unread books mean ______.A.your wrong lifelong learning attitudeB.you limit yourself off from the unknownC.your have no interest in the new worldD.your strong desire for new information（3）What’s the author’s attitude towards having an antilibrary?A.Favorable.B.Doubtful.C.Ambiguous.D.Contradictory.（4）What can we know from the last paragraph?A.Curiosity is a sign of high IQ.B.Books are the ladder in our life.C.Unread books are surely relevant to the bad attitude.D.We should read through every book.【答案】CDAB【考点】推理判断议论文阅读观点态度词义猜测细节理解日常生活类阅读【解析】本文是一篇议论文。

AMany schools across the US hold graduation ceremonies this timeof year. In some schools, even 5 and 6-year-olds observe their graduation from kindergarten. And so can older people, much older. Meet 70-year-old Jerry Reid, who just graduated from the Universityof Virginia in Charlottesville. He earned a bachelor’s degree.Mr. Reid might not look like the average college student; hishair is definitely grayer. But still Jerry Reid’s age is easy to forget, other UVA students know him as one of their own.Mr. Reid sat into the “Hoo Crew,” a group that cheers loudlyfor the school at sports events. He also joined a men's group on campus. He sang drinking songs along with many other students. Mr. Reid’s school friends say they can talk to him just about anything.About a half century ago, in his 20s, Mr. Reid was not in school. Instead, he was racing cars and chasing girls. But he says his friend Bill invited him to UVA parties.“Bill told me what a terrible life I had unless I came up here and went to school with him,” said Reid.That was in 1963. Jerry Reid says it took him 48 years to take that advice. In 201X, he entered college. UVA Professor Luke Wright says Mr. Reid influences students. He opened the minds of the young adults. The teacher says Mr. Reid showed them that life does not end at 40. Instead, the 70-year-old college graduate believes thatgetting older can be the beginning of a dream.“Remember that path that you left waits for you. It’s there. It’s yours.

AMany schools across the US hold graduation ceremonies this time of year. In some schools, even 5 and 6-year-olds observe their graduation from kindergarten. And so can older people, much older. Meet 70-year-old Jerry Reid, who just graduated from the University of Virginia in Charlottesville. He earned a bachelor’s degree.Mr. Reid might not look like the average college student; his hair is definitely grayer. But still Jerry Reid’s age is easy to forget, other UVA students know him as one of their own.Mr. Reid sat into the “Hoo Crew,” a group that cheers loudly for the school at sports events. He also joined a men's group on campus. He sang drinking songs along with many other students. Mr. Reid’s school fr iends say they can talk to him just about anything.About a half century ago, in his 20s, Mr. Reid was not in school. Instead, he was racing cars and chasing girls. But he says his friend Bill invited him to UVA parties.“Bill told me what a terrible life I had unless I came up hereand went to school with him,” said Reid.That was in 1963. Jerry Reid says it took him 48 years to take that advice. In 2011, he entered college. UVA Professor Luke Wright says Mr. Reid influences students. He opened the minds of the young adults. The teacher says Mr. Reid showed them that life does not end at 40. Instead, the 70-year-old college graduate believes that getting older can be the beginning of a dream.“Remember that path that you left waits for you. It’s there. It’s yours. All you must do is to get out of your own way and get back to it. And, that's exactly what I did,” said Reid.Mr. Reid says that he and his wife Susan now would take some time off to enjoy his college degree. Then, he’ll return to UVA to begin studying for his graduate degree.21. Which of the following is true of Mr. Reid?A. He was laughed at by other students.B. He was interested in study in his youth.C. He enlarged the views of young people.D. He got his graduate degree at the age of 70.22. From the third paragraph, we can infer that Mr. Reid was _________.A. considerateB. independentC. intelligentD. energetic23. What does Paragraph 6 mainly discuss?A. How Mr. Reid realizes his dream.B. What teachers think of Mr. Reid.C. When Mr. Reid entered college.D. Why the students likes Mr. Reid.24. What lesson can we learn from the story of Jerry Reid?A. It is never too late to learn.B. Two heads are better than one.C. Actions speak louder than words.D. A friend in need is a friend indeed.BRaymond Wang, 17, of Canada was awarded first place for a device that improves air quality on airplanes while cutting down the spreading of diseases at this year’s Intel International Science and Engineering Fair (ISEF).According to Intel, Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent, while cutting diseases by up to 55 times, compared to conventional designs.

After you’ve done sightseeing in London, shopping in New York, enjoyed the local food in Paris, and danced to your heart’s content at the Brazilian carnival, where else can you go? What attractive tourist destination awaits you?Well, Antarctica sounds like the holiday of a lifetime! It'sconsidered the last great wilderness on Earth. Just a few scientists in research stations share the icy landscape with penguins and other animals which can struggle with the low temperatures.Tourism began in Antarctica in the 1950s and it's still small part. About 37,000 tourists are expected there this season, but many won't even leave the boat.The BBC’s Juliet Rix visited the frozen continent and asked herself if she should be there at all, causing potential problems to such a sensitive environment. Her tour guide admitted that all visitors leave a footprint and they all go to the same places, the accessible coastline, which is also where the penguins and seals go to raise.But some people believe that if carefully controlled, tourism can be good for Antarctica. It has no native population and it needs advocates. Visitors to the icy continent might be ready to support and even to fund its preservation. And they're likely to engage in the discussion about global warming, which has led to the melting of glaciers.According to Rix, guidelines are followed when you’re about to set foot in Antarctica and tourists have to disinfect(消毒)their boots to make sure no alien species are introduced.And once on land, there's no eating or smoking. Rocks, bone fragments—nothing should be taken as a souvenir and nothing should be left behind.Tourists fortunate enough to visit the Antarctic must be aware that this is not their home and keep their fingers crossed that future generations will also be able to enjoy such breathtaking views.28. Who lives in Antarctica?A. 37,000 tourists.B. The BBC's Juliet Rix.C. A few scientists and animals.D. People in London and Paris.29. Why can tourism be good for Antarctica?A. People can bring some animals into it.B. People may take interest in the protection of it.C. People can give advice to the native population.D. People will go to the coastline to play with the seals.30. What are the guidelines when you go on the shore?A. You can leave rubbish on the shore.B. You can smoke and eat on the shore.C. You can take something as souvenirs.D. You can help to protect the environment.31. What is the author’s attitude towards the tourists going to Antarctica?A. Positive.B. Ambiguous.C. Subjective.D. Negative.DUntil recently, scientists had mapped only about 20 percent of the sea floor. But our knowledge of the deep seas is changing because of information from satellites. Scientists have produced a new map that provides a detailed picture of the oceans. The map is expected to help oceanographers (海洋学家), industry and governments.The new map is twice as detailed as the map made 20 years ago. David Sandwell is a geophysics professor at the University of California. He and other scientists worked on the mapping project. He says they turned to space to look deeper into the ocean.The scientists collected and studied information from two satellites. Some of the data came from the European SpaceAgency’s Cryo-2 satellite. It was placed in Earth's orbit to watch sea ice. The other satellite is the American space agency's Jason-1. It is studying the surface of the oceans. Scientists combined the satellite data with images gathered by sonar (声波定位仪) equipment on ships. Sonar works by sending sound waves through the water. When the sound waves hit an object, its presence is confirmed.The new map shows the sea floor as it has never been seen before. It shows thousands of underwater mountains and places where continents pulled apart. It shows where earthquakes were active many years ago. They all are buried deep underneath the ocean floor.David Sandwell says the map is a powerful tool for fisheries, those interested in protecting the environment and for oil exploration.“The petrol exploration industry is interested i n how to reconnect the continents, bring them back together tectonically so you can map the basins on one continental edge—say, Africa—and use that to establish where the similar basin would be on the other continental edge in South America.”If scientists know that information, they may be able to find oil fields. The new data also will help scientists improve their estimates of ocean depths. This information can help ships travel safely and improve military operations and scientific projects worldwide.Mr. Sandwell thinks scientists will make many more discoveries as they examine the new map and the information it provides.32. Which one is not mentioned about the benefits brought by the new map?A. Fisheries.B. Scientific projects.C. Ship manufacture.D. Oil exploration.33. What can we know about the new map?A. It shows where earthquakes will happen.B. It will be helpful to industry and governments.C. It is three times as detailed as the old one years ago.D. It shows the sea floor as it has ever been seen before.34. The text is likely to appear in _________.A. a newspaperB. an advertisementC. a science magazineD. a finance report35. Which of the following can be the best title for the text?A. The detailed picture of the oceansB. Underwater mountains and placesC. More discoveries about the oceansD. Scientists create new maps of ocean floor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。
