Most people will agree that the thatched roof is an essential part of the attraction of the English countryside.Thatching is in fact the oldest of all the building crafts(工艺)practised in the British Isles. Although thatch has always been used for cottage and farm buildings, it was once used for castles and churches, too.Thatching is a solitary(独自的)craft, which often runs in families. The craft of thatching as it is practised toady has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, keeping and renewing the old roofs as well as thatchingnewer houses. Many property owners choose thatch not only for its beauty but because they know it will keep them cool in summer and warm in winter.In fact, if we look at developing countries, over half the world lives under thatch, but they all do it in different ways. People in developing countries are often unwilling to go back to traditional materials and would prefer modern buildings. However, they may lack the money to allow them to get the necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective defiance against the heat.56. Which of the following remains a special feature of the English countryside?A. Narrow streets lined with pink or white houses.B. Rolling hills with pretty farm buildingsC. Cottages with thatched roofs.D. Churches with cottages around them.57. What do we know about thatching as a craft?A. It is a collective activity.B. It is practised on farms all over England.C. It is quite different from what it used to be.D. It is in most cases handed down among family members.58. Thatched houses are still preferred because of _________.A. their style and comfortB. their durabilityC. their easy maintenanceD. their cheap and ready-made materials59. People in developing countries also live under thatch because ________.A. thatched cottages are a big tourist attractionB. thatched roof houses are the cheapestC. thatch is an effective defense against the heatD. they like thatched houses better than other buildings(B)Today our lives are changing faster than at any time in history. Here we report on three important changes that will have a big impact on our everyday lives in the future.The cashless societyCash and bank-notes will disappear almost completely. They will be replaced by smart cards, namely plastic cards microchip(微芯片)processors(处理器)loaded with some money. When we pay for goods,the shop assistant will put our smart card into a payment terminal(终端)and money will come into his card from our card. When all the money is used up,we will be able to reload it by putting it into a telephone,dialing our bank account and money will be put into the card from the account.Interactive telephonesTalking computers will play an important part. They will recognize speech, ask us what information we need, look through a database,and put the information into speech.If we want to book a flight or pay a bill by phone, we will interact with a talking computer to do so. Human telephone operators will be used only for more complex operations such as dealing with complaints or solving special problems._________Traffic jams in cities will to find the quickest route to their destination. Electronic systems will start changing motorists for driving in cities.As soon as motorists have to pay to drive in cities, they will stop using their cars and use public transport instead. Speed control systems will be built into cars. These systems will automatically(自动地)regulate the speed of the car to take account of traffic and weather conditions and prevent accidents. It will be many years before these changes bring results but when they do,there will be a titanic improvement in road safety.With the development of science and technology, more and more advanced things will be invented or created. Life in the future is undoubtedly different from that at the present.60. Cash and bank-note will disappear because .A. they will be out of use sooner or laterB. they will be replaced by plastic cards convenient to useC. we can load money from the bankD. they will be rejected by payment terminalsbe reduced because drivers will use electronic route maps61. What will you do if the money in your card is used up?A. Go to the bank to deposit some money.B. Put the card into a telephone and dial the bank account.C. Buy a new card.D. We don’t know.62. Which of the following would be the best subtitle for the fourth paragraph?A. Future carsB. Speed control systemsC. Intelligent carsD. Traffic jams63. Which of the following statements is NOT true?A. When we buy tickets for flying somewhere else, we can have a talk with the computer.B. If you make a complaint, you can use human telephone operation.C. Drivers will stop using their cars and use public transport in order to prevent accidents.D. The help of electronic route maps will decrease traffic jams.64. The underlined word “titanic” in Paragraph 4 means .A. huge and greatB. the name of a shipC. slightD. increasing(C)Dolphins(海豚)are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this, they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brain is nearly the same size as our own, and they live a long time―at least twenty or thirty years. Like some animals, dolphins use sound to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area-except for The Penguin.Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.65. Dolphins are different from many other animals in that they _____.A. live in groupsB. have large brainsC. are warm-bloodedD. have their own language66. Which of the following does the dolphin use to help it find its way around?A. Its nose.B. Its ears.C. Its mouth.D. Its eyes.67. Why did the sailors off the coast of New Zealand look for Jack?A. He was lonely and liked to be with people.B. They enjoyed playing with him.C. He was seriously wounded.D. They wanted his help.68. By telling the story of Jack, the writer wanted to show that _____.A. dolphins are friendly and cleverB. people are cruel to animalsC. Jack is different from other dolphinsD. dolphins should be protected by law(D)Hotlines have become common in China. Some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows T hat’s a good idea. Yet, the fact is, some people do nothing but break the whole program.Some people know little about the topic under discussion. Sometimes they do not even know what the host is talking about. So the host has to tell the caller what the show is about. Usually the caller will ask a few questions which express his hope and show his ignorance (无知). Then the host has to answer and explain—how silly this is! It wastes a lot of time.It seems that some people phone the hotlines for fun. They just want to let the listeners hear them. They don’t care what the topic is, whether they themselves are interested or how silly they appear to be.I’m totally bored by those people. It’s necessary for radio stations to improve the hotline programmers. In my opinion, if a caller does not know what is going on, the operator should not let the caller take part in it.69. The sentence “some people do nothing but break the whole program” may tell us that _____.A. radio stations use hotlines in a wrong wayB. it is a factC. it is a good ideaD. some people have unclear thoughts70. So me calls waste the host’s time __________.A. because the host works hardB. because of the caller’s ignoranceC. because the host likes talking to the callerD. because of a lot of questions raised by the callerEIt’s you and I who are to blame for the state of the earth . No question about it . It’s our life-style that is threatening life on Earth , so we must make the changes . The good news is that many of those changes are really quite simple , even enjoyable , but for every careful step we take as individuals , we must press government and industry to take a big step on our benefit . And we must start now . Tomorrow’s too late .My aim this year is to persuade as many of my friends and colleagues as possible to choose the train , and leave their cars behind too . My gardens have been pesticide(杀虫剂)–free zones for years and I enjoy seeing more wildlife on my doorstep as a result; I’ve tried to reduce my contribution to water pollution too, by using environment-friendly, phosphate(磷)–free washing powder , and by no longer thinking of the toilet as a. suitable waste-disposal(处理) point .I ran after a young lady through town recently to give her back the piece of paper she had carelessly thrown away. She disappeared into a shop,and when I followed her inside and made my presentation, she was doubly embarrassed--she worked there,and the boss gave her a ticking –off too. I’ve started asking fellow drivers at gas stations why they aren’t using unleaded (无铅的) petrol . These are small things , but we have to start somewhere , and every little does help .71.We can learn from the first paragraph that .A.you and I are responsible for looking after the environmentB.the government and industry are responsible for looking after the environmentC.the government is responsible for looking after the environmentD.both A and B72.To help the environment , the author is trying to do everything mentioned below EXCEPT A.taking the train instead of a car B.throwing away the old carsC.avoiding the use of pesticidesD.running after those who throw articles carelessly73.The author ran after a woman through town because he wanted .A.to find out where she workedB.to give her back the piece of paper she had lostC.to tell her not to throw away pieces of paper carelesslyD.to ask her to pay him for picking up the piece of paper.74.The word “ticking-off ”in the last paragraph probably means .A.blaming B. a piece of paper C.prize D. ticket75.The purpose of this passage is to .A.persuade his friends to take the trainB.inform us of the good newsC.make clear who is responsible for the environmentD.try to advise us all to protect our environment五、短文改错(每题1分共10分)此题要求改正所给短文中的错误。

Well, it is a big question that you always ask yourself.There is no short cut to success, which is the first thing you should remember. For this reason you have to study hard first of all. Besides, here are some tips for you.Never fear or hate exams and be confident. Some students study well but still may be afraid of exams and due to this reason they won’t be able to get good marks. So le ave all your fears behind and free your mind before starting your studies. You have to be confident and it is the most important thing for attaining victory.Prepare a good timetable. Prepare a timetable before starting your studies. This should include all subjects, but tough subjects can be given more time while easier ones less. And remember some time shall be spared for entertainment and also there should be enough break time between each subject.Select a proper atmosphere for studying. No need to ex plain this point. Can anyone study well while watching TV? So select a place where you feel comfortable and can concentrate. And importantly it is better to study early in the morning when you will have quiet surroundings and you can concentrate more.Make notes while studying. This is a very important point. Make small notes while studying can help you remember all the points. It will work better if you use these notes for revision in the last one or two hours than you skip through pages of your textbook. It won’t take much time to go through these notes.Write well. As we all know, the first impression is the best impression. So your handwriting affects your marks. Try to write neatly. If it is not good enough, don’t worry; if you present it in a good manner you can score more marks.36.Which proverb can show the writer’s attitude towards our studies?A. No pains, no gains.B. Knowledge is power.C. It’s never too old to learn.D. Nothing is impossible for a willing heart.37.Why do some students hate exams according to the passage?A. Because they think exams are meaningless.B. Because preparing for exams takes up most of their time.C. Because there are too many exams at school.D. Because they don’t have enough self-confidence.38.Why does the writer say “No need to explain this point” in Paragraph 5?A. Because it’s difficult to explain.B. Because it’s easy to understand.C. Because we need to study in silence.D. Because a proper atmosphere can be formed anywhere.B“Long time no see” is a very interesting sentence.When I first read this sentence from an American friend’s email,I laughed.I thought it was a perfect example of Chinglish.Obviously,it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on,my friend told me that it is a standard American greeting.I was too thrilled to believe her.Her words could not convince me at all.So I did a research on Google.com.To my surprise,there are over 60 thousan d web pages containing “Long time no see.” This sentence has been widely used in emails,letters,newspapers,movies,books,or any other possible places.Though it is sort of informal,it is part of the language that Americans use daily.Ironically,if you type this phrase in Microsoft Word,the software will tell you that the grammar needs to be corrected.Nobody knows the origin of this Chinglish sentence.Some people believe that it came from Charlie Chan’s movies.In the 1930s,Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens.Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius(孔子).“Long time no see” was his trademark.Soon after Charlie Chan,“Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.Some scholars refer to America as a huge pot of “stew”.All kinds of culture are mixed in the stew together,and they change the color and taste of each other.American Chinese,though a minority ethnic(少数民族的成员)group in the United States,is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.You can have some other examples than adoptions from Chinese,such as pizza from Italian,susi from Japanese,and déjà vu from French etc.There is a long list! Americans do not just simply borrow something from others.They will modify it and make it their own,so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant,or to buy a bottle of iced Chinese green tea with honey in a grocery store.Since Americans appreciate Chinese culture more and more nowadays,I believe more Chinese words will become American English in the future.In this way the American stew keeps adding richness and flavor.39.The writer himself felt surprised at ______.A.the Chinglish expression “Long time no see”B.“Long time no see” used as standard American EnglishC.so many literal translation of the expressions used in AmericaD.finding out Americans use the expression every day40.The word “stew” in the 4th paragraph probably means ______.A.mixture literature B.Confucius’ wordsC.a kind of cooked dish D.American changing cultures41.According to the passage,it can be inferred that ______.A.detectives translate the phrase “Long time no see”B.Hollywood made “Long time no see” popularC.the huge pot of stew greatly affects all kinds of languagesD.cultures can be changed in the huge pot of stew42.The main idea of the passage is that ______.A.some Chinese expressions are introduced into EnglishB.you’ll not be surprised at a tofu in a restaurant in AmericaC.some American expressions can be used in ChinaD.American English keep being enriched from different culturesCTracey Hermanstorfer's heart stopped beating and her son Coltyn appeared lifeless after the Caesarean(剖腹产术)section on Christmas Eve. However a few minutes after he was born, both began breathing again. Dr Stephanie Martin told Good Morning America she could not explain how the pair survived. Mrs Hermanstorfer and her husband Mike told the American television show that their baby was now healthy and that they were doing“good”following the drama at Colorado Springs Memorial Hospital.The couple, who already had two children, had to go into the hospital seven weeks earlier than planned. Her husband, 37, said his wife was tired after receiving an epidural(硬脑膜外麻醉)during the labour(分娩)but after closing her eyes, she “wasn't waking up”.She stopped breathing and she is believed to have suffered a heart attack before her heart stopped beating entirely.Dr Martin said she was called in and that the outlook was grim(严酷的)since in most situations like this,“despite the best efforts of the team”, the mother was often unable to be revived. In that case doctors then tried to focus on delivering the baby but when he was born he was “completely lifeless”.Mr. Hermanstorfer told the Associated Press news agency,“I had everything in the world taken from me, and in an hour and a half I had everything given to me.”Dr Martin said she did not have a“great explanation”for why Mrs Hermanstorfer's heartbeat returned. “Somewhere between four and five minutes she had been without heart rate and had stopped breathing a minute or two prior to her heart stopping,”she said. The doctors were then able to bring the baby back to life, and the mother was alive after that.Despite tests, she said doctors were still not sure about what had happened. However Mrs Hermanstorfer and her husband Mike have said they believed it was down to a miracle. She said:“I got a second chance in life.”43.What might have happened to Tracey Hermanstorfer just before her heart stopped beating?A.She became unconscious. B.She took a nap.C.She had a bad headache. D.She suffered a heart attack.44.Which of the following is the correct order of what happened to Tracey Hermanstorfer?a.suffering a heart attackb.stopping heart beating entirelyc.stopping breathingd.coming back to lifee.receiving an epiduralf.producing a babyA.a c f d b e B.f c a d b e C.e a c b f d D. e a b c f d45.Which of the following words best expresses Dr Martin's attitude towards Tracey Hermanstorfer's coming back to life?A. Shocked.B. Puzzled. C.Normal. D. Curious.第二节根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
