For each question, there are four choices marked A, B, C arid D. You should decide on the best choice, then mark the corresponding letter on the answer sheet with a single line through the center.Questions 46-50 are based on the following passage.Mark Twain pointed out that if work were so pleasant, the rich would keep it for themselves. But however much people may think they dislike work, everyone has a deep psychological need for it. Everyone wants to be valued, and wages and salaries are the visible proof that we matter.Not all kinds of work qualify, however. No matter how worthwhile or demanding they might be, bringing up children, housework and voluntary employment are not usually seen as proper jobs. The only proper job is one that provides paid employment. Being paid for a job in our society means higher personal status.Of course we would also prefer work to be useful, pleasant and interesting—and also well paid. But you don’t really have to enjoy your work to get pleasure from it. The fact that we have to overcome some difficulties that we have to deal with doing routine tasks, in some way gives us pleasure.For example, having to be in a particular place at a particular time, working as part of a team towards a common goal, gives us a sense of purpose. The modern workplace also provides somewhere where people can assert their identity or create a new one.Without work many people become untidy and lazy, and find they are unable to enjoy the leisure time which is available to them. When some people retire from work, they lose their sense of value and purpose. For most of their lives, their personality, self-image and status have been defined by work; without it they lose their appetite for life.People who suddenly lose their jobs can find the situation particularly difficult. At a single stoke they lose all the advantages and status that a paid job provides. In a culture dominated by work, they are seen by those with jobs as incompetent or lazy. It is little wonder that stress and illness occur more frequently among the unemployed.Employment is now changing, however. Information technology has already significantly altered the world of work. For many, the idea of a job for life is no longer realistic. Many people fear they will lose their jobs, and some are being persuaded to accept the possibility of part-time work. Even the workplace itself may become a thing of the past with more and more people working at home. This means that we may no longer be able to depend on work to define ourselves and our position in society, and that we will have to find new ways to give our lives a sense of value and purpose.Questions:46. Mark Twain pointed out that______.A. the rich should work moreB. work is not such a pleasurable thingC. the rich should keep all the work for themselvesD. work makes people rich47. People have a deep psychological need for work because______.A. they want to be richB. they like being told what to doC. everyone needs moneyD. they want to be valued and work proves this value48. People don’t have to enjoy their work to get pleasure from it because______.A. the salary makes them happyB. they get used to the routineC. coping with problems can be satisfyingD. they know their work is still useful49. People who have no work often______.A. enjoy their leisure timeB. develop a better self-imageC. have difficulty coping with the changeD. take an interest in new activities50. The arrival of information technology has______.A. enhanced people’s interest in workB. made work more stressfulC. made the workplace unnecessaryD. made people change their attitude to workSection B (10 marks)by a summary. Read the by choosing a maximum of three words from the passageCompanies say that in many cases, the benefits of foreign-language knowledge can lie outside the specific realm of business. That’s one reason why the programs are optional. Mayer says that the benefits are more to help each employee adjust to his or her new surroundings and to promote the company’s policy of being a good neighbor and becoming integrated into local communities than to help the executive conduct actual business.At IBM, company-subsidized foreign-language training is provided on a case-by-case basis, says Mia Vanstraelen, director of human resources for learning in Europe, the Middle East and Africa. If employees need foreign-language skills to do their job properly—for example, an expatriate manager who functions as the point person between an overseas operation and headquarters or a sales employee who deals with clients on the ground overseas—the company will provide financial support. In addition, company support is often available for employees seeking business-related skills to further their own careers within the company.A less-than-aggressive attitude toward foreign-language acquisition at the corporate level is typical, some experts say, and the reasons range from high cost to a lack of necessity. English, the language of business, the language of technology, the language of Hollywood, is the language to know in global business even for traditionally non-English-speaking countries.While Americans have to decide which second language might be most useful for their business careers according to their areas of interest, potential business professionals in other countries whose native language is not English have a clear answer to that question. And as more students worldwide learn to conduct business in English, its position as the language of commerce solidifies.Even multinationals that are headquartered in other countries are using English as the language of business, Van Some ren says. He cites Sony’s Berlin headquarters as an example. In that office, which has about 400 employees, there are 45 different nationalities and almost as many languages, he says. “So the cost and effort associated with trying to teach everyone German when a lot of them will be moving on to other assignments in a matter of months probably doesn’t make a lot of sense,” he says. Language acquisition can be a slow process, and companies that need someone who speaks a foreign language can’t wait years for t he right employee to gain the skills. When knowledge of a foreign language is what is specifically required, that’s the skill set human resources looks for. Lieberthal says that in manyways, training high-level employees in a foreign language such as Chinese simply doesn’t make good business sense. “It’s a large investment with high front-end costs.” Top executives could harm their careers by taking time off to study a language. In addition, he says, even if an executive were willing to put in the time to learn a language, the training just doesn’t make economic sense. An employer would have to not only cover the cost of language training as well as the executive’s salary, but also absorb whatever financial burden results from lost productivity. An executive sitting in the classroom memorizing vocabulary could be an investment in the future, but it would be a very costly one, Lieberthal says, and one that might not produce great returns.Part VI IQ Test (5 minutes,5 marks)There are five IQ question in this part.

J.L. and Barbara Hammond said that steam power “declared the triumph of industry and the glory of man”. From clumsy and inefficient beginnings it was quickly improved to open up tremendous possibilities for industrial progress. The limitations of muscle—power are obvious, and though water had served well to work bellows and hammers in iron works，or to turn machinery like the water-frame and the mule in the textile industry, it could only be applied in a limited way in Britain. For water power is most useful in a land with many fast-flowing streams and apart from areas like the Pennines, Scotland, and Wales, this country’s rivers flow slowly. The Alpine area of Europe, and much of the United States relied on water power for much longer than Britain, and hydroelectricity has brought water back into its own in many parts of the world. The geographical limitations of Britain’s water power, however, necessitated finding an alternative solution to the problem.When water vaporizes it expands 1,800 times. The idea of harnessing this energy is far from new. It was probably used by Hero of Alexandria in the 1st century B.C. to open temple doors or to pour libations apparently by magic. Hero’s writings were rediscovered during the Renaissance and many people, including, for example, the Marquis of Worcester (1601-1667) experimented with devices using steam. Regretfully, therefore, we must dismiss the old myth that steam power was born in the mind of a bright Scots lad called James Watt as he sat one winter’s evening watching his mother’s kettle boil on the hearth. Watt’s contribut ion to steam is incalculable, but steam-pumps had been used in Britain for over seventy years before he began his work.The first steam-engine used in industry was invented by Thomas Savery (1650-1715). Called “The Miners’ Friend or an engine to raise water by fire”, it was patented in 1698 and worked on simple principles. It pumped water from wells quite efficiently and was used successfully in Cornish copper-mines, but its limitations were revealed when it was tried in the Broadwater Collieries in Staffordshire in 1706 and was found to be capable of pumping water up no more than 100 feet. When greater pressure was used the boiler burst. Therefore, Savery’s engine was used to supply water in gentlemen’s houses or to work fountains—tasks it could perform effectively, though not quite safely as there was no pressure-gauge.It was Thomas Newcomen (1663-1729), a Dartmouth blacksmith and ironmonger, who produced the first steam-pump to be used widely in industry. It was known as an “atmospheric engine” because, in contrast to Savery’s engine, the steam in the cylinder was not used to drive the pump but only to create a partial vacuum when condensed. Ordinary air pressure drove the piston into the cylinder and this raised the pump which was connected to the piston by a see-sawing cross-beam. A large piston meant that it was possible to gain more force without increasing steam pressure and this made Newcomen’s engine much more powerful than Savery’s.The first engine was made about 1706 but it was a clumsy affair. The piston did not fit tightly into the cylinder and condensation，which was achieved by pouring cold water on the outside of the cylinder，was far from complete. Moreover，the tap controlling the passage of steam into the cylinder was worked by hand seven or eight times a minute. These difficulties were ironed out by 1720；water was now sprayed into the cylinder toimprove condensation, the operation of the taps had been made automatic,and a safety-valve had been fitted to eliminate the danger of explosion.The improved engine soon became standard equipment in most large mines，and it was also used to pump water into canals and to supply drinking-water in towns. It is difficult to know exactly how many were in useby the second half of the 18th century but in 1767 fifty-seven were found around Newcastle，and there were eighteen in Cornish mines in 1780. Questions:61. Why could water power only be applied in a limited way in Britain?62. Who was the first person mentioned in the text trying to use steam power?63. Who invented the first steam engine used in industry?64. How was Newcomen’s engine different from that of Savery’s?65. What was installed to the first engine to prevent explosion?Part Ⅳ Cloze (15 minutes, 15 marks)Read the following passage and fill in each blank with one word. Choose the word in one of the following three ways: according to the context; using the correct form of the given word; according to the given letters of a word. Remember to write the answers on the answer sheet.There are many wedding traditions in the West. And some of them date back to several hundreds of years and most of their origins have their (66) r in ancient superstitious beliefs.“Something old, new, borrowed and blue” is a popular bridal attire (盛装) rhyme. It dates from the Victorian times. Something old refers (67) wearing something that represents a link with the bride’s family and her (68) (precede) life. Usually, the bride wears a piece of family jewelry or maybe her mother’s or grandmother’s wedding dress. Wearing something new (69) (symbol) good fortune and success in the bride’s new life.The bride’s wedding dress is usually chosen, or purchased new, (70) bit can be any other new item of the bride’s wedding attire. Weari ng something borrowed is meant to (71) b good luck to the marriage. It could be an item of bridal clothing, a handkerchief or an item of jewelry. Wearing something blue dates back to biblical times (72) the color blue was considered to represent purity and fidelity.The custom of the wedding veil is thought to (73) pre the wedding dress by centuries. One explanation for it is that during the times of arranged marriage, the bride’s face was covered until the groom was committed (74)her at the ceremony—so it would be too late for him to run off if he did notlike the look of her! It is also thought that rite veal was worn to (75) pr the bride from evil spirits that would be floating around on her wedding day. This is why the ve al covers the brides’ face throughout the ceremony until the minister (76) p the couple man and wife.And traditionally a bride’s (77) (engage) ring and wedding ring are worn on the fourth finger of the left hand. (78) Th no precise evidenceexplains the origin of this tradition, one belief is strongly held to it. It (79) ori from the 17th century. During a wedding then, the priest arrived at the fourth finger (80) a touching the three fingers on the left hand “... in the nameo f the Father, the Son and the Holy Ghost”.Part Ⅴ Translation (15 minutes, 20 marks)Section A (10 marks)Translate the underlined sentences of the following passage into Chinese. Remember to write the answers on the answer sheet.(81) For many women choosing whether to work or not to work outside their home is a luxury: they must work to survive. Others face a hard decision.Perhaps the easiest choice has to do with economics. One husband said, “Marge and I decided after careful consideration that for her to go back to work at this moment was an extravagance (奢侈) we couldn’t afford”. (82) With two preschool children, it soon became clear in their figuring that with babysitters, transportation, and increased taxes, rather than having more money, they might actually end up with less.Economic factors are usually the first to be considered, but they are notthe most important. The most important aspects of the decision have to do with the emotional needs of each member of the family. (83) It is in this area that husbands and wives find themselves having to face many confusing and conflicting feelings.(84) There are many women who find that homemaking is boring or who feel imprisoned (被囚禁) if they have to stay home with a young child or several children. On the other hand, there are women who think that homemaking gives them the deepest satisfaction.From my own experience, I would like to suggest that sometimes the decision to go back to is made in too much haste. There are few decisions that I now regret more. I wasn’t mature enough to see how much I could have gained at home. (85) I regret my impatience to get on with my career; I wish I had allowed myself the luxury of watching the world through my little girl’s eyes.Section B (10 marks)86. 有时候对一个人来说需要终生的时间才能懂得活着就是为了奉献。
