Write your answer on your Answer Sheet.Passage OneIf you know exactly what you want, the best route to a job is to get specialized training. A recent survey shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the –job training.That’s especially true of booming fields that are challenging for workers. At Cornell’s School of Hotel Administration, for example, bachelor’s degree graduates get an average of four or five job offers with salariesranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies, especially, like a background of formal education couples with work experience.But in the long run, too much specialization doesn’t pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but the impact of a degree washes out after five years.As further evidence of the erosion (销蚀) of corporate (公司的) faith in specialized degrees, Michigan State’s Schertz cites a pattern in corporate hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle-and upper-level management. “They want someone who isn’t constrained (限制) by nuts and bolts to look at the big picture,” says Schertz.This sounds suspiciously like a formal statement that you approve of the liberal-arts graduate. Them and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and adaptability, and the ability to analyze and solve problems. David Birch claims he does not hire anybody with an MBA or and engineering degree. “I hire only liberal-arts people because they have a less-than-canned way of doing thing,” says Birch. Liberal-arts means an academically thorough and strict program that includes literature, history, mathematics, economics, science, human behavior-plus a computer course or two. With that under your belt, you can feel free to specialize. “A liberal-arts degree coupled with an MBA or some other technical training is a very good combination in the marketplace,” says Schertz.1. What kinds of people are in high demand on the job market?A. Students with a bachelor’s degree in humanities.B. People with an MBA degree from top universities.C. People with formal schooling plus work experience.D. People with special training in engineering.2. By saying “…but the impact of a degree washes out after five years”(Line 3, Para. 3), the authormeans .A. most MBA programs fail to provide students with a solid foundationB. an MBA degree does not help promotion to managerial positionsC. MBA programs will not be as popular in five years’ time as they are nowD. in five people will forget about the degree the MBA graduates have got3. According to Schertz’s statement (Lines 3~4, Para. 4), companies prefer .A. people who have a strategic mindB. people who are talented in fine artsC. people who are ambitious and aggressiveD. people who have received training in mechanics4. David Birch claims that he only hires liberal-arts people because .A. they are more capable of handling changing situationsB. they and stick to established ways of solving problemsC. they are thoroughly trained in a variety of specialized fieldsD. they have attended special programs in management5. Which of the following statements does the author support?A. Specialists are more expensive to hire than generalists.B. Formal schooling is less important than job training.C. On-the-job training is, in the long run, less costly.D. Generalists will outdo specialists in management.Passage TwoWith fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well.Another new project is being setup to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this:First, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed;then it will pass through a powerful fan to separate the lightest elements from the heavy solids;after that founders and rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets, which will remove the bits of iron and steel;the rubber and plastic will then be sorted out in the final stage.The first full-scale giant recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.6. The phrase “should be well on with...”(Para. 1)most probably means _______.A. have completed what was startedB. get ready to startC. have achieved a great deal inD. put an end to7. What is NOT mentioned as a part of the recycling process described in paragraph 3?A. Breaking up whatever is breakable.B. Sharpening metal bars.C. Separating light elements from the heavy ones.D. Sorting out small pieces of metal.8. What’s the main reason for big cities to build their own recycling plants?A. To deal with wastes in a better way.B. To protect the environment from pollution.C. To get raw materials locally.D. To get big profits from those plants.9. The first full-scale huge recycling plants _______.A. began to operate fifteen years agoB. will probably take less than fifteen years to buildC. will be built fifteen years laterD. will probably be in operation in fifteen years10. The passage is mainly about _______.A. a cheap way to get energyB. the location of recycling plantsC. new ways of recycling wastesD. the probability of city environmentPassage ThreeIn some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence –as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instincts remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering mean nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us.The truly reasonable men who know where the solutions lie are finding it harder and herder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social programme. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law.Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other’s problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. ‘Talk, talk, talk,’ the advocates of violence say, ‘all you ever do is talk, and we are none the wiser.’ It’s rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. ‘Possible, my lord,’ the barrister replied, ‘none the wiser, but surely far better informed.’ Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.11. What is the best title for this passage?A. Advocating Violence.B. Violence Can Do Nothing to Diminish Race Prejudice.C. Important People on Both Sides See Violence As a Legitimate Solution.D. The Instincts of Human Race Are Thirsty for Violence.12. Recorded history has taught us _______________.A. violence never solves anything.B. nothing.C. the bloodshed means nothing.D. everything.13. It can be inferred that truly reasonable men __________.A. can’t get a hearing.B. are looked down upon.C. are persecuted.D. have difficulty in advocating law enforcement.14. “He was none the wiser” meansA. he was not at all wise in listening.B. H e was not at all wiser than nothing before.C. H e gains nothing after listening.D. H e makes no sense of the argument.15. According the author the best way to solve race prejudice isA. law enforcement.B. knowledge.C. nonviolence.D. Mopping up the violent mess.Passage FourFor a long time, researchers have tried to nail down just what shapes us --- or what, at least, shapes us most. And over the years, they've had a lot of exclamation moments. First it was our parents, particularly our mothers. Then it was our genes. Next it was our peers, who show up last but hold great sway. And all those ideas were good ones --- but only as far as they went.Somewhere, there was a sort of temperamental dark matter exerting an invisible gravitational pull of its own. More and more, scientists are concluding that this unexplained force is our siblings.From the time we are born, our brothers and sisters are our collaborators and co-conspirators, our role models and cautionary tales. They are our scolds, protectors, goads, tormentors, playmates, counselors, sources of envy, objects of pride. They teach us how to resolve conflicts and how not to; how to conduct friendships and when to walk away from them. Sisters teach brothers about the mysteries of girls; brothers teach sisters about the puzzle of boys. Our spouses arrive comparatively late in our lives; our parents eventually leave us. Our siblings may be the only people we'll ever know who truly qualify as partners for life. "Siblings," says family sociologist Katherine Conger, "are with us for the whole journey."Within the scientific community, siblings have not been wholly ignored, but research has been limited mostly to discussions of birth order.Older sibs were said to be strivers;younger ones rebels;middle kids the lost souls.The stereotypes were broad,if not entirely untrue,and there the discussion mostly ended.But all that’s changing.At research centers in the U.S.,Canada,Europe and elsewhere,investigators are launching a wealth of new studies into the sibling dynamic,looking at ways brothers and sisters steer one another int0—or away from--risky behavior how they form a protective buffer(减震器)against family upheaval;how they educate one another about the opposite sex;how all siblings compete for family recognition and come to terms--or blows--over such impossibly charged issues as parental favoritism.From that research,scientists are gaining intriguing insights into the people we become as adults.Does the manager who runs a harmonious office call on the peacemaking skills learned in the family playroom? Does the student struggling with a professor who plays favorites summon up the coping skills acquired from dealing with a sister who was Daddy’s girl? Do husbands and wives benefit from the inter—gender negotiations they waged when their most important partners were their sisters and brothers? All that is underinvestigation.“Siblings have just been off the radar screen until now,”says Conger.But today serious work is revealing exactly how our brothers and sisters influence us.16.The beginning of the passage indicates thatA.researchers have found out what shapes us.B.our peer is the last factor influencing us.C.what researchers found is good and trustworthy.D.what researchers found contributes in a limited way.17.In the third paragraph, the author tries to demonstrate that our siblingsA.offer us much useful information.B.have great influences on us.C.are the ones who love us completely.D.accompany us throughout our life.18.In scientific community, previous research on siblingsA.mostly focused on the sibling order.B.studied the characteristics of the kids.C.studied the matter in a broad sense.D.wasn’t believable and the discussion ended.19.Which of the following is NOT sibling dynamic?A.A brother cautions his sister against getting into trouble.B.Sisters have quarrels with each other.C.Siblings compete for parental favoritism.D.Older kids in a family try hard to achieve.20.From the last paragraph,we can conclude thatA.managers learned management skills from the family playroom.B.spouses learned negotiation skills from their siblings.C.studies on siblings are under the way。

To contemplate the philosophy underlying individualism.C. To examine the trend of young people living alone.D. To stress the rebuilding of personal relationships.Passage TwoAmerican dramas and sitcoms would have been candidates for prime time several years ago. But those programs -though some remain popular -increasingly occupy fringe times slots on foreign networks. Instead, a growing number of shows produced by local broadcasters are on the air at the best times.The shift counters longstanding assumptions that TV shows produced in the United States would continue to overshadow locally produced shows from Singapore to Sicily. The changes are coming at a time when the influence of the United States on international affairs has annoyed friends and foes alike, and some people are expressing relief that at least on television American culture is no longer quite the force it once was.“There has always been a concern that the image of the world would be shaped too much by American culture,” said Dr. Jo Groebek, director general of the European Institut e for the Media, a non-profit group. Given the choice, he adds, foreign viewers often prefer homegrown shows that better reflect local tastes, cultures and historical events.Unlike in the United States, commercial broadcasting in most regions of the world -including Asia, Europe, and a lesser extent Latin America, which has a long history of commercial TV -is a relatively recent development.A majority of broadcasters in many countries were either state-owned or state-subsidized for much of the last century. Governments began to relax their control in the 1980’s by privatizing national broadcasters and granting licenses to dozens of new commercial networks. The rise of cable and satellite pay-television increased the spectrum of channels.Relatively inexperienced and often financed on a shoestring, these new commercial stations needed hours of programming fast. The cheapest and easiest way to fill airtime was to buy shows from American studios, and the bidding wars for popular shows were fierce.The big American studios took advantage of that demand by raising prices and forcing foreign broadcasters to buy less popular programs if they wanted access to the best-selling shows and movies.“The studio priced themselves out of prime time,” said Harry Evans Sloan, chairman of SBS Broadcasting, a Pan-European broadcaster. Mr. Sloan estimates that over the last decade, the price of American programs has increased fivefold even as the international ratings for these shows have declined.American broadcasters are still the biggest buyers of American-made television shows, accounting for 90% of the $25 billion in 2001 sales. But international sales which totaled $2.5 billion last year often make the difference between a profit and a loss on show. As the pace of foreign sales slows -the market is now growing at 5% a year, down from the double-digit growth of the 1990’s -studio executives are rethinking production costs.6. Which of the following best characterizes the image embodied in American shows?A. Self-contradictoryB. Prejudice-freeC. Culture-loadedD. Audience-targeted7. The intervention of governments in the 1980’s resulted in __________ .A. the patenting of domination shows and moviesB. the emergence of new commercial networksC. the promotion of cable and satellite pay-televisionD. the intense competition coming from the outside8. The phrase “on a shoestring” (Para. 6) most probably means __________.A. in need of capitalB. after a fashionC. on second thoughtsD. in the interests of themselves9. The main reason why American dramas and sitcoms are driven out of prime time is that ____.A. they lose competitivenessB. they are not market-orientedC. they are too much pricedD. they fall short of audience expectations10. American studio producers will give thought to production costs __________.A. if they have no access to popular showsB. because their endeavors come to no availC. since bidding wars are no longer fierceD. as international sales pace slows downPassage ThreeHow shops can exploit people's herd mentality to increase sales1. A TRIP to the supermarket may not seem like an exercise in psychological warfare—but it is. Shopkeepers know that filling a store with the aroma of freshly baked bread makes people feel hungry and persuades them to buy more food than they had intended. Stocking the most expensive products at eye level makes them sell faster than cheaper but less visible competitors. Now researchers are investigating how “swarm intelligence” (th at is,how ants,bees or any social animal,including humans,behave in a crowd) can be used to influence what people buy.2. At a recent conference on the simulation of adaptive behaviour in Rome,Zeeshan-ul-hassan Usmani,a computer scientist from the Florida Institute of Technology,described a new way to increase impulse buying using this phenomenon. Supermarkets already encourage shoppers to buy things they did not realise they wanted: for instance,by placing everyday items such as milk and eggs at the back of the store,forcing shoppers to walk past other tempting goods to reach them. Mr Usmani and Ronaldo Menezes,also of the Florida Institute of Technology, set out to enhance this tendency to buy more by playing on the herd instinct. The idea is that, if a certain product is seen to be popular, shoppers are likely to choose it too. The challenge is to keep customers informed about what others are buying.3. Enter smart-cart technology. In Mr Usmani's supermarket every product has a radio frequency identification tag, a sort of barcode that uses radio waves to transmit information,and every trolley has a scanner that reads this information and relays it to a central computer. As a customer walks past a shelf of goods, a screen on the shelf tells him how many people currently in the shop have chosen that particular product. If the number is high, he is more likely to select it too.11. freshly baked bread 12. visible level 13. impulse buying14. screen 15. discounts16.No17. Not given18. No 19. Yes 20. YesPart II.

Part I: Reading Comprehension 40%Directions: Read the following passages carefully and then select the best answer from the four choices given to answer the questions or to complete the statements that follow each passage. Write your answer on your Answer Sheet.Passage OnePsychologists agree that I.Q. contributes only about 20 percent of the factors that determine success. A full 80 percent comes from other factors,including what I call emotional intelligence. Following are two of the major qualities that make up emotional intelligence,and how they can be developed:1. Self-awareness. The ability to recognize a feeling as it happens is the keystone of emotional intelligence. People with greater certainty about their emotions are better pilots of their lives.Developing self-awareness requires tuning in to what neurologist Antonio Damasio calls ―gut feelings‖。

IMAX公司之所以开始大规模地进行影院投资,基于一个关键技术的突破:2008年3月,IMAX成功推出新的数字放映系统。数字化成为IMAX公司扩张的助推器。过去,一部普通格式的电影要转换成IMAX电影,需要高达400万美元的成本,单个胶片拷贝成本在2.5万-4.5万美元之间。数字技术让每部电影的转换成本降低到150万美元,存放在硬盘上的数字拷贝只需要200美元。在成本大幅降低之后,作为提升票房的重要砝码,每个片方都想把自己的电影转制成IMAX格式。就这样,IMAX终于克服了高成本的门槛,迎来了在全球市场的高速成长。

一、单项选择题(每小题3分,共45分)1.当政府采用限价方式平抑蔬菜价格,会造成蔬菜市场( )。
A .需求量减少,供给量减少,市场过剩B .需求量增加,供给量减少,市场短缺C .需求量增加,供给量增加,市场短缺D .需求量减少,供给量增加,市场过剩【答案】B【解析】为了抑制某些产品价格上涨,政府往往实行最高限价。
最高限价也称为限制价格,是政府所规定的最高价格,最高价格总是低于市场的均衡价格。
如图1-1所示,当最高限价0P 低于均衡价格e P 时,12e Q Q Q <<,所以结果是需求量增加,供给量减少,市场短缺。
图1-1 最高限价2.如果价格降低时,收入效应为负,同时符合需求法则,则该商品为( )。
A .吉芬(Giffen )品B .正常品C .劣等品D .奢侈品【答案】C【解析】价格降低时,收入效应为负,说明该商品是劣等品或者吉芬商品。
但是由于其符合需求法则,即价格降低,最后的需求量是增加的,所以降价时,该商品的收入效应小于替代效应,即该商品是劣等品。
3.若消费者具有线性需求函数,当价格达到50元时将不再有购买,如果企业现在定价为35元,则可以判断此时需求价格弹性为( )。
A .富有弹性B .缺乏弹性C .单一弹性D .完全弹性【答案】A【解析】由已知得线性需求函数可表示为()50Q a P =-,当35P =时,15Q a =,则此时需求价格弹性为:()d 3571d 153d Q P E a P Q a =-⋅=--⨯=>,故需求价格富有弹性。
