Grammar and VocabularySection ADirections:After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)The California state assembly recently approved the so-called Paris Hilton bill, which prevents dogs 25______ occupying the driver’s seat in a moving vehicle. The bill passed 26______ Democrats wanted to make an example of Miss Hilton. They think she is a “little rich girl” who always gets her way; plus, her daddy is a big contributor to the Republican Party. “The judge 27______ have put her in jail for four months,” said one Democrat when Paris got only a four-day jail sentence for driving while drunk.28______ (drive) around town with her little dog Lovey hanging out the driver's window, Paris is a familiar sight throughout Los Angeles. Pictures of her and Lovey are common in newspapers and magazines.“That dog is a deadly threat to everyone on the streets and the sidewalks,” said assembly leader Fabian Nunez. “We wrote this bill to protect the public. There’s no telling 29______ the dog might cause her to drive into a crowd of pedestrians. 30______ Paris wants to be with her dog, let her chauffeur do the driving. The state assembly is responsible for protecting people, and we take that responsibility seriously.”The assembly bill passed by a vote of 44 to 11. The state senate(参议院) 31______(expect) to approve the bill, and Governor Schwarzenegger has promised to sign it. “I love dogs,” he said, “but when it comes to 32______ (protect) the people of California, dogs will have to t ake a back seat.”The eleven assembly members who objected to the bill were all Republicans. “While Californians,”said Republican Tom Ridge, “are being attacked daily by murderers, rapists, and muggers, who do the Democrats protect citizens from—a 33______ (spoil) little girl and her dog!”(B)He almost killed somebody, but one minute changed his life. This beautiful story comes from Sherman Rogers’ book, Foremen: Leaders or Drivers? .In his true-life story, Rogers illustrates the importance of effective relationships. During his college years, Rogers spent 34______ summer in an Idaho(爱达荷州) logging camp. When the superintendent had to leave for a few days, he put Rogers in charge.“35______ if the men refuse to follow my orders?” Rogers asked. He thought of Tony, an immigrant worker who roared all day, giving the other men a hard time.“Fire them,” the superintendent said. Then, as if 36______ (read) Roger’s mind, he added, “I suppose you think you are going to fire Tony if you get the chance. I’d feel badly about that. I have been logging for 40 years. Tony is the most reliable worker I’ve ever had. I know he hates everybody and everything. But he comes in first and leaves last. There has not been an accident for eight years on the hill 37______ he works.”Rogers took over the next day. He went to Tony and spoke to him.“Tony, do you know I’m in charge here today?” Tony grunted（发哼声）. “I was going to fire you thefirst time we fought, but I want you to know I’m not,”he told Tony, adding what the superintendent 38______ (say).When he finished, Tony dropped the shovelful of sand he had held and tears streamed down his face.“Why he no tell me dat eight years ago?”That day Tony worked harder than ever before --- and he smiled! He later said to Rogers, “My first foreman who ever say, ‘Good work, Tony’ and it made me feel like Christmas.”Rogers went back to school after that summer. Twelve years later he met Tony again who was now superintendent for railroad construction for one of 39______ (large) logging companies in the West. Rogers asked him how he came to California and happened to have such success.Tony replied, “If it not be for the one minute you talk to me back in Idaho, I keel somebody someday. One minute change my whole life.”Effective managers know the importance of taking a moment to point out 40______ a worker is doing well. But what a difference a minute of affirmation can make in any relationship!Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.A. reassuresB. wellC. distinguishD. encounterE. objectsF. inoffensiveG. revealsH. afterwardsI. implicationJ. genuineK. unpleasantTelling Tales“Here’s a nice bit of gossip!” Do I have your attention? Probably. We listen, but 41______ we often feel terrible with ourselves. That’s the problem with gossip: it’s something that as a social species we are primed to enjoy, but it can also be 42______ and harmful.Not all gossip is bad. Small talk establishes relationships and 43______ the other person that our intentions are friendly. So gossip, in the sense of exchanging bits and pieces of news about ourselves and others, can be perfectly 44______. If I say to you, “L et’s meet for coffee andhave a bit of a gossip,”I’m inviting you to a social 45______ in which twopeople chew the fat. There is nothing wrong with that: life would be verydull if we were unable to talk about what goes on around us.But it’s not that simple. If we say that somebody is a gossip, we do notmean that he or she enjoys gentle social chat: it carries a crueler 46______.A true gossip enjoys spreading stories about other people --- stories in which others do not usually come out 47______. The gossip is one who spreads bad gossip; good gossip is still fine, but it’s not what gossips spread. The distinction between good and bad gossip is not always clear. It would be easy if we could 48______ the two by saying that bad gossip is just about people; but innocent gossip may be about people too. The best way to tell the difference is to look at the intention behind the remarks. Bad gossip 49______ itself in its desire to make the 50______ of the story look foolish. It also intrudes on their privacy. So we all know the difference.Now then, did you hear about ...III. Reading ComprehensionSection ADirections: For each blank in the following passages there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.“What are you going to be when you grow up?” is a question that you may have been asked. You may not even know there are a variety of geography-related jobs.The Association of American Geographers lists nearly 150 different geography jobs. So, if you are interested in people, places, and environments, consider a job in geography. Your work will not be limited to maps—it might range from 51 data to planning projects, or making decisions about the environment.Processing Geographic DataA geographer’s main activity is analyzing geographic information to answer geographic questions. Jobs processing geographic data begin, of course, with collecting the information. One on-the-ground job in data collection is that of a surveyor. Surveyors 52 and measure the land directly. They may mark boundaries, study the shape of the land, or even help find sewer(下水道) and water systems beneath the Earth. High-tech information-gathering jobs include working with Geographic Information Systems (GIS) data. Some examples of these jobs include remote sensing specialists and GIS analysts. Data analysis jobs require the ability to think 53 , high-level computer skills, and a college education.Once data have been processed, a geographer may study the information to use in planning projects such as a new urban area, a(n) 54 evacuation(撤退) plan, or the placement of a new highway. Planners can also help determine how to make a neighborhood a better place to live. These jobs, too, require good critical thinking, writing, and computer skills, as well as a college education. Planners are 55 to the success of a community.Advising Businesses and GovernmentAbout half of jobs using geography are in business and government. All kinds of businesses use geographic information to help build and 56 their operations. A location analyst studies an area to find the best location for a client. The client might be a large retail store chain that wants to know which location would be best for opening a new store. The location analyst can study GIS reports on such elements as transportation networks or population in an area and give the business owners the positive and 57 points about a location being considered.In 1967, the Mexican government was looking for a location to create a new international tourist resort. They used location analysts to find an area that had good beaches and was easy to reach from the United States. The 58 was Cancún, today one of the world’s most desirable vacation sites.Businesses connected with natural 59 such as forests also rely on geographers. Geographers help them understand the relationship between their business and the environment where their business is located.In 1967, Cancún was a small island on Mexico’s Caribbean coast. It had white sand beaches, many birds and mangrove(红树) trees, but few people. After it was selected as a resort site, it was quickly 60 . Today, Cancún has more than 100 hotels and 500,000 permanent residents. Many work in the tourist industry that serves the millions of visitors who come each year from all over the world.Physical and Human GeographyPhysical geographers are sometimes called earth scientists. Some study such topics as geomorphology (地形学), that is, the study of how the shape of the Earth 61 . Others study weather and climate. Still others study water, the oceans, soils, or ecology. Jobs in these fields require 62 scientific training.Some geographers study economic, political, and 63 issues as they relate to place or region. Human geographers are usually hired by government agencies to analyze a specific problem. These geographers work 64 with political scientists, economists, and sociologists.Together, they provide possible solutions to problems from many different aspects of life in an area. And, of course, geographers teach the subject at all levels of 65 , from elementary schools to universities. But no matter what geography jobs people might hold, they are always trying to answer the basic geographic questions: “Where are things located?” and “Why are they there?”51.A. performing B. analyzing C. appreciating D. downloading52.A. map B. mine C. shape D. honour53.A. creatively B. critically C. wildly D. moderately54.A. disaster B. radioactivity C. excursion D. vacation55.A. qualified B. determined C. valuable D. feasible56.A. survive B. expand C. manage D. boom57.A. negative B. effective C. depressive D. profitable58.A. scenery B. destination C. result D. foundation59.A. potentials B. histories C. resources D. sciences60.A. specialized B. polluted C. governed D. transformed61.A. proceeds B. stretches C. extends D. changes62.A. peculiar B. special C. reasonable D. enthusiastic63.A. psychological B. contemporary C. religious D. social64.A. closely B. peacefully C. loyally D. sensitively65.A. demonstration B. revolution C. examination D. educationSection BDirections:Read the following passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)The Dangers of DietingThanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people crazily search for a solution to this problem, they often try some of the popular fad(时尚) diets being offered. Many people see fad diets as harmless ways of losing weight, and they are grateful to have them. Unfortunately, not only don’t fad diets usually do the trick, but they can actually be dangerous for your health.Although permanent weight loss is the goal, few are able to achieve it. Experts estimate that 95 percent of dieters return to their starting weight, or even add weight. While the irresponsible or unwise useof fad diets can bring some initial results, long-term results are very rare.Nonetheless, people who are bored with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one t ype of food, or they prohibit other types of foods entirely. This results in a situation where a person’s body doesn’t get all the vitamins and other things that it needs to stay healthy.One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates（碳水化合物）. A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss.Veteran(老兵) dieters may well ask at this point, “What is the ideal diet?” Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British study quoted above recommends a diet that is high in carbohydrates and high in fiber, with portions of fatty foods kept low. According to the study, such a diet is the best for people who want to stay healthy, lose weight, and keep that weight of f. And, any dieting program is best undertaken with a doctor’s supervision.66.After losing weight by dieting, what usually happens to people?A. They have kidney failure.B. They gain the weight back again.C. They keep the weight off.D. They have less muscle.67.Which of the following best expresses the essential information in paragraph 3?A. Bored people turn to fad diets, which, being too extreme, don’t give the body everything itneeds.B. People are bored with fad diets and turn to diets which provide what the body needs.C. People prefer fad dieting to moderate dieting because it requires fewer foods to give the body whatit needs.D. Fad diets give boring people the moderate dietary changes they need to get all the requiredvitamins.68.Which is not mentioned as an effect of the meat and animal product diet?A. Heart disease.B. Slower weight loss.C. Psychological changes.D. Kidney failure.69.According to the passage, why does the ideal diet depend on the individual?A. The less muscle you have, the less food you use up.B. Everyone can gain the weight back.C. Everyone has a different psychology.D. Everyone likes different foods.(B)Charlie Bell became chief executive of McDonald’s in April. Within a month doctors told him that he had colorectal cancer. After stock market hours on November 22nd, the fast-food firm said he had resigned; it would need a third boss in under a year. Yet when the market opened, its share price barely dipped then edged higher. After all, McDonald’s had, agai n, shown how to act swiftly and decisively in appointing a new boss.Mr. Bell himself got the top job when Jim Cantalupo died of a heart attack hours before he was due to address a convention of McDonald’s franchisees(获特许经营联营店者). Mr. Cantalupo was a McDon ald’s veteran brought out of retirement in January 2003 to help remodel the firm after sales began falling because of dirty restaurants, indifferent service and growing concern about junk food. He devised a recovery plan, backed by massive marketing, and promoted Mr. Bell to chief operating officer. When Mr. Cantalupo died, a rapidly convened(召集) board confirmed Mr. Bell, a 44-year-old Australian already widely seen as his heir apparent, in the top job. The convention got its promised chief executive’s address, from the firm’s first non-American leader.Yet within weeks executives had to think about what to do if Mr. Bell became too ill to continue. Perhaps Mr. Bell had the same thing on his mind: he usually introduced Jim Skinner, the 60-year-old vice-chair man, to visitors as the “steady hand at the wheel”. Now Mr. Skinner, an expert on the firm’s overseas operations, becomes chief executive, and Mike Roberts, head of its American operations, joins the board as chief operating officer.Is Mr. Roberts now the new heir apparent? Maybe. McDonald’s has brought in supposedly healthier choices such as salads and toasted sandwiches worldwide and, instead of relying for most of its growth on opening new restaurants, has turned to upgrading its 31,000 existing ones. America has done best at this; under Mr. Roberts, like-for-like sales there were up by 7. 5% in October on a year earlier.The new team’s task is to keep the revitalization plan on course, especially overseas, where some American brands are said to face political hostility from consumers. This is a big challenge. Is an in-house succession(交替、继承) the best way to tackle it? Mr. Skinner and Mr. Roberts are both company veterans, having joined in the 1970s. Some recent academic studies find that the planned succession of a new boss from within, such as Mr. Bell and now (arguably) Mr. Roberts, produces better results than looking hastily, or outside, for one. McDonald’s smooth handling of its serial misfortunes at the top certainly seems to prove the point. Even s o, everyone at McDonald’s must be hoping that it will be a long time before the firm faces yet another such emergency.70.The main reason for the constant change at the top of McDonald is _______.A. the constant change of its share priceB. the board’s failure to reach an agreementC. the falling salesD. the physical problems of the chief executives71.The underlined phrase “heir apparent” (in Paragraph 2) in the article most probably means someonewho _______.A. has the same ideas, aims and style with a personB. has the same right to receive the family titleC. is appointed as an executive of a companyD. is likely to take over a person’s position when that person leaves72.Which of the following was NOT a cause of the falling sales of McDonald?A. The change of the chief executive.B. People’s concern about junk food.C. Dirty restaurant.D. Indifferent service.73.In terms of succession at the top, McDonald_______.A. has had to made rather hasty decisionsB. prefers to appoint a new boss from withinC. acts in a quick and unreasonable wayD. surprises all the people with its decisions(C)It is evident that there is a close connection between the capacity to use language and the capacities covered by the verb “to think”. Indeed, some writers have identified thinking with using words: Plato coined the saying, “In thinking the soul is talking to itself”; J. B. Watson reduced thinking to inhibited(拘谨的) speech located in the minute(微小的) movements or tensions of the physiological mechanisms involved in speaking; and although Ryle is careful to point out that there are many senses in which a person is said to think and in which words are not in evidence, he has also said that saying something in a specific frame of mind is thinking a thought.Is thinking reducible to, or dependent upon, language habits? It would seem that many thinking situations are hardly distinguishable from the skillful use of language, although there are some others in which language is not involved. Thought cannot be simply identified with using language. It may be the case, of course, that the non-linguistic skills involved in thought can only be acquired and developed if the learner is able to use and understand language. However, this question is one which we cannot hope to answer in this book. Obviously being able to use language makes for a considerable development in all one’s capacities but how precisely this comes about we cannot say.At the common-sense level it appears that there is often a distinction between thought and the words we employ to communicate with other people. We often have to struggle hard to find words to capture what our thinking has already grasped, and when we do find words we sometimes feel that they fail to do their job properly. Again when we report or describe our thinking to other people we do not merely report unspoken words and sentences. Such sentences do not always occur in thinking, and when they do they are merged with vague imagery and the hint of unconscious or subliminal（潜意识）activities going on just out of rage. Thinking, as it happens, is more like struggling, striving, or searching for something than it is like talking or reading.Again the study of speech disorders due to brain injury disease suggests that patients can think without having adequate control over their language. Some patients, for example, fail to find the names of objectspresented to them and are unable to describe simple events which they witness; they even find it difficult to interpret long written notices. But they succeed in playing games of chess or draughts. They can use the concepts needed for chess playing or draught playing but are unable to use many of the concepts in ordinary language. How they manage to do this we do not know. Presumably human beings have various capacities for thinking situations which are likewise independent of language.74.According to the theory of "thought" devised by J. B. Watson, thinking is_______.A. talking to the soulB. concealed speechC. speaking nonverballyD. a non-linguistic behavior75.What does the author think about the relationship between language and thinking?A. The ability to use language enhances one’s capacity of thinking.B. Words and thinking match more often than not.C. Thinking never goes without language.D. Language and thinking are generally distinguishable.76.According to the author, when we intend to describe our thoughts, we______.A. merely report internal speechB. have to search for proper words in the way we readC. are overwhelmed with vague imageryD. sometimes are not able to find appropriate words77.Why are patients with speech disorders able to think without having adequate control of language?A. They use different concepts.B. They do not think linguistically.C. It still remains an unsolved mystery.D. Thinking is independent of language.Section CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Space Travel and Science FictionSpace travel and science fiction have long been connected. Early science fiction writers such as Jules Verne inspired scientists and engineers to develop new space technologies. Writers of science fiction, as well as creators of science fiction TV shows and movies, often study the latest scientific concepts and use or adapt them to help expose what future space travel, space ships, and space stations might look like. And while many of their predictions have come true, many others have not.Jules Verne (1828-1905) was a French author. He was a pioneer of science fiction. In his novels From the Earth to the Moon(1865) and Around the Moon(1870), a kind of space ship is fired from a 900-foot-long cannon(大炮) at the moon. On their journey, the three travelers are deprived of gravity at one point and float around their small ship. When landing on the moon, rockets are used to slow the ship down.Given the year in which he was writing, Verne’s predictions were very good. The size of his space ship is about the size of the first one to go to the moon, the Apollo, minus its l arge rockets. Both Verne’s ship and the Apollo carried three people into space. Furthermore, rockets were indeed used by the Apollo to slow its descent. However, Verne’s ship, by analogy(相似) with a gun, shot his travelers into space, which never could have worked. The intense pressure of such an event would cause great physiological damage to the crew.During the first half of the 20th century, science fiction novels and comic books were widely distributed in the United States. Their portrayal(描写) of space travel was less far-fetched than Verne’s. Pictures began showing astronauts in space suits, as writers realized that exposure of human beings to space was deadly. Ideas of other planets were still often wrong, though. A 1928 drawing of the surface of a moon of the planet Jupiter shows it covered in plant life. Only later was it discovered that other than Earth, the planets and moons around our sun are without life as we know it. Drawings in the early 20th century showed very large space ships and stations. They were like floating cities. Writers at the time knew that trips to other stars would take hundreds of years. Those who left Earth would die on the journey; their descendants would arrive. Some writers avoided this problem by using the concept of suspended animation —a deep sleep in which a person doesn't grow older. Such travelers would awaken at the end of their journey, hundreds of years in the future. It is not impossible that these ideas could become reality one day.After the American space program had begun, the television show Star Trek became very popular. It follows the adventures of a large space ship with over 400 crew members that flies around the universe at speeds faster than light. This is a wonderful dream, but it will probably never come to fulfillment. The laws of physics tell us that it is quite impossible for any object to travel faster than the speed of light.It’s clear to see that science fiction has progressed along with science and technology. Science fiction writers continue to study scientific concepts and to use them to portray the future. Looking back at their ideas, some were correct and cannot be distinguished from today’s reality; many others were nothing but fiction. But, they have always inspired new generations of humans to dream of someday going into space.78.According to the passage, what did early science fiction writers do to help reveal what future spacetravel might look like?79.If the modern spaceship were shot into space by analogy with a gun, the astronauts in it would___________________________.80.The space travelers in early science fictions didn’t wear space suits, because___________________________________________________.81.According to the passage, suspended animation was a concept used in science fiction to_______________________________(Note: Answer the questions or complete the statements in No More Than Twelve Words.)。

流派不是独木桥刘连群①流派的学习和继承，一直是京剧界深为关注的话题。

在好长一段时期里，呼唤创造新流派的声音很强烈，不时见诸于报刊和有关的学术研讨，成为引导流派传承的“主旋律“．然而近30年过去了，新的流派没有产生，反倒是现有流派的抢救、保护问题显得突出和紧迫起来。

在今年纪念张派艺术创始人张君秋先生诞辰90周年的活动期间，大家发表对于流派传承的看法，有的强调原原本本、原汁原味，也有张派传人表示学习多年，由于本身是女性，嗓音、气力总也赶不上老师，今后要汲取前人的艺术精华，尝试走自己的路，等等，只是没有人再提创造新的流派。

②这就颇值得思索。

表面看，对新流派的呼声转低，是基于新派的难产，久唤不至而不免无奈和失落，细究起来，在一定程度上，包含着对前一阶段思路的某种务实和纠偏。

呼唤新流派并没有错，进一步丰富京剧表演艺术的风格特色，是京剧界内外的共同愿望，问题在于新流派的形成和创立，离不开多方面的因素，不仅凭借演员的艺术根基和努力，还受着剧种历史发展阶段和社会生存环境的制约，因此不是单纯的提倡和引导所能奏效的。

这也是当前新流派难产的根本原因。

③同时，在对传统流派的传承导向中，单一地强调另创新派，以此作为衡量传承水平的唯一标准和终极目标，也有失片面。

比如，有一种流行的说法是“学余派最好是杨宝森“，依据自然是杨宝森先生在学习余派的基础上创出了杨派。

后者确实是非常了不起的艺术成就，杨派极大地丰富了京剧老生演唱艺术，其贡献和影响怎么称誉也不过分，但若就以此论定学余“最好“，可以设想一下，余派传人都按此“最好“去下工夫，余派本身谁来传呢？还传得下来吗？依此逻辑推而广之，京剧多姿多彩的名家流派包括杨派、张派在内，岂不都将失传，从舞台上消失吗？这恐怕是任何人都不愿意看到的情景。

④事实上，深入了解京剧流派传承的历史，高水平传承的方式是存在多样性的。

（16分） 流派不是独木桥 刘连群 临"书"我永远记得那个夜晚。

悲怆的声音一点点变得平和，变得快乐。

因为一声稚嫩的喝彩。

那是乡下的冬天，乡下的冬天远比城市的冬天漫长。

常有盲人来到村子，为村人唱戏。

他们多为夫妻，两人一组，带着胡琴和另外一些简单的乐器。

大多时候村里会很晚。

在娱乐极度匮乏的年代，那是村里人难得的节日。

让我感兴趣的并不是那些粗糙的表演，而是他们走路时的样子。

年幼的我常常从他们笨拙的行走姿势中找到属于自己的卑劣的快乐。

那是怎样一种可笑的姿势啊！男人将演奏用的胡琴横过来，握住前端，走在前面。

女人握着胡琴的后瑞，小心翼翼地跟着自己的男人，任凭男人胡乱地带路。

他们走在狭窄的村路上，深一脚浅一脚，面前永远是无边的黑夜。

雨后，路上遍布着大大小小的水洼，男人走进去，停下，说，水。

女人就笑了，不说话，却把胡琴攥得更紧。

然后换一个方向，继续走。

换不换都一样，到处都是水洼。

在初冬，男人的脚，总是湿的。

那对夫妻在村里演了两场。

地点在村委大院，两张椅子就是他们的舞台。

村人或坐或站，聊着天，抽着烟，跺着脚，打着呵欠，一晚上就过去了。

没有几个人认真听戏。

村人需要的只是听戏的气氛，而不是戏的本身。

要演最后一场时，变了天。

严寒在那一夜，突然蹿进我们的村子。

那夜滴水成冰，风像刀子，直接刺进骨头。

来看戏的人，无几。

村长说要不明天再演吧？男人说明天还得去别的村。

村长说要不这场就取消吧？男人说，说好三场的。

村长说就算取消了，钱也是你们的，不会要回来。

男人说没有这样的道理。

村长撇撇嘴，不说话了。

夫妻俩在大院里摆上椅子，坐定，拉起胡琴，唱了起来。

他们的声音在寒风中颤抖。

加上我，总共才三四名观众。

我对戏没有丝毫兴趣，我只想看他们离开时，会不会被冰的水洼滑倒。

天越来越冷，村长终于熬不住了。

他关掉村委大院的电灯，悄悄离开。

Whenever she walks into a room, heads turn. Her friends wonder how she managed to get the new Mulberry handbag that no one had thought was 41 in Australia yet.The truth is that Olivia has never left Australia. But with a few clicks of her computer mouse, she can travel to shopping 42 around the world. Online shopping has 43 the consumer experience. With the help of an increasing number of online shops overseas, shoppers can now pick up interesting goods from all over the world.The biggest advantage of shopping on foreign websites is the wide range of choices available. For example, Chinese shoppers are often disappointed when Gap products are not available locally. But now it‘s possible to order these products straight from the US with a credit card and a small 44 fee. Other benefits of online shopping include 45 prices. When items are bought online from other countries, they‘re often tax-free.However, when you buy things from a foreign website, things can get 46 too. So make sure you pay extra attention to protecting your rights.Sometimes it can be difficult to handle foreign websites because of the unfamiliar language. For example, the term ―shipped in 1-5 working days‖ can be confusing for Chinese shoppers, as it doesn‘t clarify whether this is the time in which the product will arrive or the time it takes for it to be 47 .The method of shipping can also determine whether you get your product at all. Unless you choose express or priority shipping, which only takes a few days to deliver but is more expensive, most 48 international shipping doesn‘t offer a tracking option ― which means once your products are shipped outside of the country there‘s no way of finding out where they are.The best consumers are the most sensible ones. If you‘re interested in expanding your shopping 49 to foreign websites, make sure you do your research beforehand to avoid your money and products being lost on the way.III. Reading ComprehensionSection ADirections:For each blank in the following passage there are four words or phrases marked A,B,C and D. Fill in each blank with the word or phrase that best fits the context.Starting around 1348, the plague(瘟疫) hit the continents of Europe and Asia. As a result, it killed an 50 forty million people. This disease has come to be known as the Black Death. Its victims suffered a horribly painful death 51 by fever and dying, blackened flesh.Although they are not certain, many historians agree that the Black Death probably originated in China and spread through trade 52 , carried by fleas (跳蚤)found on rats. Rats are very common in cities, so these areas were hit the hardest. The disease passed to humans when the fleas would jump from the rats to a human host.Every social group suffered from the Black Death---it was not a discriminating (有识别力的)disease. But those who lived in rural settings were sometimes 53 , as were the wealthy, who had less 54 with outsiders and could afford to move to more remote areas in an 55 to spare themselves.The Black Death had many long-term 56 . Certain areas of Europe were nearly 57after it, including some of its prosperous cities. For example, Bremen, Germany, lost almost 7,000 of its 12,000 inhabitants; Florence, Italy, lost 40,000 of its nearly 90,000; and Paris lost more than 50,000 of its 180,000. Major cities had to create mass graveyards where the dead could be buried. European population only began to 58 again in the last decades of the 15th century.The Black Death also brought about 59 changes. As large numbers of peasants died, there was a shortage of labor. Peasants had 60 spent generations working for the same family, but after the plague hit, they began to take advantage of the labor 61 . Workers 62 many times their usual pay for work and would sometimes move to a new lord or noble who offered 63 incentives (刺激;鼓励) and working conditions. In this way, the Black Death caused the landowning aristocracy (贵族) to lose much of their power and social 64 .50. A. enormous B. evaluated C. estimated D. expected51.

A. post B. dream C. system D. positionSection BDirections:Read the following three passages.Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)The butterfly, which is competitive swimming‘s newest stroke(划水), was developed in the mid-1930s, but it wasn‘t allowed in the Olympics until 1956. The story of the but terfly is a good illustration of how coaches and swimmers are constantly searching for ways to improve stroke efficiency.During the 1920s, the Japanese Olympic coaches used underwater photography to research stroke mechanics, and their efforts paid off wh en Japanese competitors won five of the six men‘s swimming gold medals at the 1932 Games in Los Angeles.It was a wake-up call to the rest of the swimming world, and one of the top US coaches – David Armbruster at the University of Iowa – began doing his own filming.Armbruster was seeking to make the breaststroke faster. He knew that the action of bringing their arms forward underwater slowed breaststrokes down, so he came up with a method of bringing the arms forward over the water. The revised stroke (he kept the breaststroke kick) brought great improvements in speed.The following year, Jack Sieg, an Iowa swimmer, developed a technique involving swimming on his side and beating his legs in unison（一致）similar to a fish tail. As Armbruster later explained in the book Weissmuller to Spitz: The History and Background of the Olympic Games: ―Sieg tried the same action while swimming face down. Sieg synchronized his leg action with the butterfly arm action using two leg beats to each arm pull.‖ But the kick was ruled illegal because the legs moved in the vertical (垂直的) plane.Within a few years, nearly every breaststroker was using this overarm butterfly action without the kick. The pure butterfly wasn‘t legalized for some two decades, but at the 1956 Olympics in Melbourne ‗the fly‘ became an official event.65. The best title of the article is _____.A. Why did the coaches and swimmers improve stroke efficiency?B. How did the butterfly come into being?C. How did the Japanese wake up the swimming world?D. When did ‗the fly‘ become an official event?66. The Japanese coaches use underwater photography in order to ______.A. wake up the swimming worldB. be paid more moneyC. know how to be a mechanic.D. improve stroke efficiency.67. Before the pure butterfly was officially recognized, ______ years or so had passed .A. 15B. 20C. 30D. 3568. According to the passage, which statement is NOT true?A. The Japanese coaches improved butterfly stroke.B. David Armbruster used filming to study stroke mechanics.C. Sieg came up with the idea of beating legs like a fish tail.D. The butterfly was added to the Olympics in 1956.(B)Singapore National Eye Centre―I could have lost my vision.SNEC restored my sight.”A macular hole, a hole at the most crucial part of the retina brought Bonny Huang who is from Hong Kong to the Singapore National Eye Centre for treatment. The retina is the light sensing nerve tissue at the back of the eye. In no time the potentially blinding condition was treated and his vision is now restored.―In April 2008, I noticed straight lines started to become distorted, and white patch appeared in the centre of my vision. I went to the Singapore National Eye Centre immediately. The ophthalmologist, a medical doctor who specializes in eye care and surgery, found a central macular hole in my left eye.‖The treatment of this condition involves The best part is that when I forgot some of the key points he told me, he showed no sign of resentment but instead comforted me not to worry before he went through the points again. I underwent an operation which lasted for only one hour, and maintained a face-down posture for three weeks. The result was very successful.‖―I once consulted my Ophthalmologist during his lunch time, and he attended to me withoutdelicate judgment dependent on the experience of the doctor. The success of the recovery, however, relies largely on the face-down posture by the patient.―The Ophthalmologist explained to me the operational procedures, and taught me how to comply with the post-surgery face-down posture.finishing his lunch. His understanding and concern shown towards his patients can be scarcely found in other medical centres. I am very pleased to have received timely treatment in Singapore National Eye Centre where the doctors care about their patients.‖Singapore National Eye Centre● 50 senior and experienced eye surgeons, total staff strength of 460● Ultra-modern facility with state-of-the-art technology and equipment● Quality assurance programme backed by 100% clinical audit of outcomes● High impact research teams leading to latest treatment strategies● Multi-expert approach to treatment of complex eye conditions● 250,000 outpatient visits, 14,000 major eye surgeries, 13,000 laser procedures annuallySingapore National Eye Centre11Third Hospital Avenue, Singapore168751, International Patient Service 24-hour Hotline:65-6100- 9393E-mail: ips@.sg or visit .sg69.

Latest treatment strategies result from multi-expert approach to treatment of eye diseases.C. High impact research teams are invited to deal with complex conditions.D. Nearly 11precent of the staff of SNEC are senior and experienced ophthalmologists.(C)For most thinkers since the Greek philosophers, it was self-evident that there is something called human nature, something that constitutes the essence of man. There were various views about what constitutes it, but there was agreement that such an essence exists—that is to say, that there is something by virtue of which man is man. Thus man was defined as a rational(理性的) being, as a social animal, an animal that can make tools, or a symbol-making animal.More recently, this traditional view has begun to be questioned. One reason for this change was the increasing emphasis given to the historical approach to man. An examination of the history of humanity suggested that man in our time is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called ―human nature.‖ The historical approach was strengthened, particularly in the United States, by studies in the field of cultural anthropology (人类学). The study of primitive peoples has discovered such a diversity of customs, values, feelings, and thoughts that many anthropologists arrived at the concept that man is born as a blank sheet of paper on which each culture writes its text. Another factor contributing to the tendency to deny the assumption of a fixed human nature was that the concept has so often been abused as a shield(盾牌) behind which the most inhuman acts are committed. In the name of human nature, for example, Aristotle and most thinkers up to the eighteenth century defended slavery. Or in order to prove the rationality and necessity of the capitalist form of society, scholars have tried to make a case for acquisitiveness, competitiveness, and selfishness as natural human characters. Popularly, one refers cynically（愤世嫉俗地）to ―human nature‖ in accepting the inevitability of such undesirable human behavior as greed, murder, cheating and lying.Another reason for disbelief about the concept of human nature probably lies in the influence of evolutionary thinking. Once man came to be seen as developing in the process of evolution, the idea of a substance which is contained in his essence seemed untenable. Yet I believe it is precisely from an evolutionary standpoint that we can expect new insight into the problem of the nature of man.72. Most philosophers believed that human nature ________.A. is the quality distinguishing man from other animalsB. consists of competitiveness and selfishnessC. is something partly innate and partly acquiredD. consists of rationality and undesirable behavior73. The traditional view of “human nature” was strongly challenged by ________.A. the emergence of the evolutionary theoryB. the historical approach to manC. new insight into human behaviorD. the philosophical analysis of slavery74. According to the passage, anthropologists believe that human beings ________.A. have some characters in commonB. are born with diverse culturesC. are born without a fixed natureD. change their characters as they grow up75. The author mentioned Aristotle, a great ancient thinker, in order to ________.A. emphasize that he contributed a lot to defining the concept of ―human nature‖B. show that the concept of ―human nature‖ was used to justify social evilsC. prove that he had a pro found influence on the concept of ―human nature‖D. support the idea that some human characters are inherited.Section CDirections:Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.A. Try to know more about your child.B. Being a daddy is your top priority.C. Value your child for what he is.D. Let your child teach you.E. Time is of the essence.F. Look for the good and praise it.Seven Simple Rules for DadMy main object in life is to make sure I do the best possible job raising Tommy, now aged ten. That means I have to be the best possible father I can be. I am no psychologist, but I do see what succeeds with my son and me. I also observe other fathers. Here is what I have found works best in the dad department.1.76.The key to a happy child is having a dad who is there with him consistently, day in and day out. It is far better to spend evening after evening just sitting near him while he reads a book or plays on the computer than to spend a couple of hours every Saturday buying him toys or taking in a movie.2.Share your strengths and fears.You are your child's ally, not his adversary. The child who knows that his father was once afraid of the dark, and is still afraid of needles, gets to know that his own weaknesses are part of mankind, not a unique shame.3.77.Encouragement is the primary engine of human development. I have been telling Tommy for a year now that he is a whiz in math because I know he can calculate in a nanosecond the number of toys he can buy with his allowance. Now he's a whiz in math at school too. Consistent recognition of a child's strengths is more important by far than vitamins. You deny it to them at their peril and yours.4.Do not allow your children to be rude.My son is expected to share, answer others when they greet him and congratulate those who succeed. By teaching him about politeness, I make sure he realizes that others' feelings are worth taking into account. If he can get that into his little towhead, he will have learned the most basic foundation of human interaction.5.78.A common misstatement about child development is that ―kids don't come with instruction manuals(操作指南).‖ Not true—they do. They tell you when they‘re hungry. They tell you when they're lonely or scared. They are like little guided tours of themselves. Children will tell you what they want, although not always with words. Fatigue, irritability and sadness are ways of telling Dad what they need. Look and listen.6.79.When Tommy knows he is loved for himself, not for any particular accomplishment, he has a certain peace that allows him to learn better, sleep better, play better, be more helpful around the house. Whether he becomes a rocket scientist or a plumber, I want Tommy to know he's No. 1 with me.7.80.If you decide your kids come before your sales quota or bridge game, you will find that all the other pieces of Daddyhood fall into place. When you put your kids first, you're getting the most value for every hour on earth. What‘s more, you have made the r ightest decision of your life.—BENJAMIN J. STEIN in The WashingtonianSection DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.It is estimated that around of the approximately six thousand languages that are spoken today, over three thousand of them are likely to have disappeared by the year 2100. Many of these are now classified asendangered languages and are classified as such by factors such as the number of speakers a language has, the age of the speakers, and the percentage of the youngest generation acquiring fluency in the language. For example, a language with many tens of thousands of speakers may be considered endangered if the children in the community are no longer learning the language. This scenario (情节) may happen in a place like Indonesia which as many different languages in use, but is trying to make communication easier by teaching a national language nation-wide. In another scenario, a language may only have a few hundred speakers but may not be considered endangered because all of the children in the community are learning the language.Once a language is classified as endangered, conservation efforts may be made in an attempt to revive the language. Whether or not to make such efforts is a decision which is ultimately made by the speakers of the language themselves, but success often requires a great deal of help and approval from the government or other authorities.One of the most famous language conservation success stories is that of the Welsh language. Historically, large numbers of Welsh people spoke only Welsh, but eventually English became the main language of Wales and fewer and fewer people learned Welsh. Conservation efforts began to be made in the mid-20th century with the establishment of such organizations as the Welsh Language Association in 1962. The Welsh Language Act and the Government of Wales Act, both passed in the 1990s, protected the Welsh language and made sure that English and Welsh would have equal status in Wales. Since 2000, the study of the Welsh language has been a compulsory subject in school. Today, over 22% of the population of Wales are Welsh speakers, up from 18% in 1991.81. What factors are taken into consideration when we classify languages as endangered ones, besides thenumber and the age of the speakers?82. One of the reasons why some languages go declining in Indonesia is___________________83. The word ― revive‖ in Para 2, most probably means ‗_______________________‘.84. What does the example of the Welsh language try to tell us?(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)第II卷（共45分）I .
