The basic function of money is the enable buying to be separated from selling, thus permitting trade to take place without the so called double coincidence of barter. If a person has something to sell and wants something else (1)return, it is not necessary to search for someone able and  (2)  to make the desired exchange of items. The person can sell the (3)  item for general purchasing power-that is "money"—to anyone who wants to buy it and then use the proceeds to buy the desired item Rom anyone who wants to sell it.The importance of this function of money is (4)  illustrated by the experience of Germany just after World War II,  (5)  paper money was (6)  largely useless because, despite inflationary conditions, price controls were effectively  (7)  by the American, French, and British armies of occupation. People had to (8)  to barter or to inefficient money substitutes. The result was to cut total output of the economy in half. The German "economic miracle" just after 1948 reflected partly a currency reform by the occupation authorities,  (9)  some economists hold that it stemmed primarily from the German government's  (10)  of all price controls. (11)  permitting a money economy to (12)   a barter economy.  (13)  of the act of sale from the act of purchase (14)  the existence of something that  will be generally accepted in payment-this is the " (15)  of exchange” function of money. But there must also be something that can serve as a (16)  abode of purchasing power, in which the miler holds the proceeds in the interim (17)  the first sale and the (18)  purchase, or from which the buyer can  (19)   the general purchasing power with which to pay (20)  what is bought. This is the "asset” function of money.

Crying is hardly an activity encouraged by society. Tears, be they of sorrow, anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears is likely to apologize, even when a devastating (毁灭性的)tragedy was the provocation. The observer of Wars is likely to do everything possible to put an end to the emotional outpouring. But judging from recent studies of crying behavior, links between illness and crying and the chemical composition of tears, both those responses to tears are often inappropriate and may even be counterproductive. Humans are the only animals definitely known to shed emotional tears. Since evolution has given rise to few, if any, purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance survival.Although some observers have suggested that crying is a way to elicit assistance from others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears themselves.Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress. University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.Researchers at several other institutions are investigating the usefulness of tears as a memos of diagnosing human ills and monitoring drugs.At Tulane University’s Teat Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse and exposure to medication (药物), to determine whether a contact lens fits properly of why it may be uncomfortable, to study the causes of ”dry eye" syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.At Columbia University Dr. Liasy Fads and colleagues are studying tears for clues Io the diagnosis of diseases away from the eyes. Tears can be obtained painlessly without invading the body and only tiny amounts are needed to perform highly refined analyses.1.It is known from the first paragraph that (  ).2.What does “both those responses to tears" (Line 6, Para, 1) refer to?3.“Counterproductive”(Lines 7, Para, 1) very probably means “ (  )”.  4.What does the author say about crying?5.What can be inferred from the new studies of tears?

The Welsh language has always been the ultimate marker of Welsh identity, but a generation ago it looked as if Welsh would go the way of Manx, once widely spoken on the isle of Man but now extinct. Government financing and central planning, however, have helped reverse the decline of Welsh. Road signs and official public documents are written in both Welsh and English, and schoolchildren are required to learn both languages. Welsh is now one of the most successful of Europe's regional languages, spoken by more than a half-million of the country’s three million people.The revival of the language, particularly among young people, is part of a resurgence of national identity sweeping through this small, proud nation. Last month Wales marked the second anniversary of the opening of the National Assembly, the first parliament to be convened here since 14O4.The idea behind devolution was to restore the balance within the union of nations making up the United Kingdom. With most of the people and wealth, England has always had bragging rights. The partial transfer of legislative powers from Westminster, implemented by Tony Blair, was designed to give the other members of club—Scotland, Northern Ireland, and Wales—a bigger say and to counter centrifugal forces that seemed to threaten the very idea of the union.The Welsh showed little enthusiasm for devolution. Whereas the Scots voted overwhelmingly for a parliament, the vote for a Welsh assembly scraped through by less than one percent on a turnout of less than 25 percent. Its powers were proportionately limited. The Assembly can decide how money from Westminster or the European Union is spent It cannot, unlike its counterpart in Edinburgh, enact laws. But now that it is here, the Welsh are growing to like their Assembly. Many people would like it to have more powers. Its importance as figurehead will grow with the opening in 2003, of a new debating chamber, one of many new buildings that are transforming Cardiff from a decaying seaport into a Baltimore-style waterfront city. Meanwhile a grant of nearly two million dollars from the European Union will tackle poverty. Wales is one of the poorest regions in Western Europe -only Spain, Portugal, and Greece have a lower standard of living.Newspapers and magazines are filled with stories about great Welsh men and women, boosting self-esteem. To familiar faces such as Dylan Thomas and Richard Burton have been added new icons such as Catherine Zeta-Jones, the movie star, and Bryn Terfel, the opera singer. Indigenous foods like salt marsh lamb are in vogue. And Wales now boasts a national airline, Awyr Cymru. Cymru, which means "land of compatriots," is the Welsh name for Wales. The red dragon, the nation’s symbol since the time of King Arthur, is everywhere — on T-shirts, rugby jerseys and even cell phone covers.“Until very recent time most Welsh people had this feeling of being second-class citizens,” said Dyfan Jones, an 18-year-old student. It was a warm summer night, and I was sitting on the grass with a group of young people in Llanelli, an industrial town in the south, outside the rock music venue of the National Eisteddfod, Wales's annual cultural festival. The disused factory in front of us echoed to the sounds of new Welsh bands."There was almost a genetic tendency for lack of confidence," Dyfan continued. Equally comfortable in his Welshness as in his membership in the English-speaking, global youth culture and the new federal Europe, Dyfan, like the rest of his generation, is growing up with a sense of possibility unimaginable ten years ago. ’’We used to think. We can’t do anything, we're only Welsh. Now I think that’s changing."1.According to the passage, devolution was mainly meat to (  ).2.The word “centrifogal” in the second paragraph mesas (  ).  3.Wales is different from Scotland in all the following aspects EXCEPT(  ).  4.Which of the following is NOT cited as an example of the resurgence of Welsh national identity (  ).  5.According to Dyfan Jones what has changed is(  ).

It was a cold, rainy and wholly miserable afternoon in Washington, and a hot muggy night in Miami. It was Sunday, and three games were played in the two cities. The people playing them and the people watching them tell us much about the ever-changing ethnic structure of the United States.Professional football in the United States is almost wholly played by native-born American citizens, mostly very large and very strong, many of them black, it is a game of physical strength. Linemen routinely weigh more than 300 pounds. Players are valued for their weigh and muscles, for how fast they can run, and how hard they can hit each other. Football draws the biggest crowds, but the teams play only once a week, because they get so battered.The 67.204 fans were in Miami for the final game of the baseball World Series. Baseball was once America's favorite game, but has lost that claim to basketball.Baseball is a game that requires strength, but not hugeness. Agility, quickness, perfect vision and quick reaction are more important than pure strength. Baseball was once a purely American game, but has spread around much of the New World. In that Sunday's final, the final hit of the extra inning game was delivered by a native of Columbia. The Most Valuable Player in the game was a native of Columbia. The rosters of both teams were awash withHispanic names, as is Miami, which now claims the World Championship is a game that may be losing popularity in America, but has gained it in much of the rest of the world. Baseball in America has taken on a strong Hispanic flavor, with a dash of Japanese added for seasoning.Soccer, which many countries just call football, is the most widely enjoyed sport in the world. In soccer, which many countries just call football, the ethnic tide has been the reverse of baseball. Until recently, professional soccer in the United States has largely been an import, played by south Americans and Europeans. Now, American citizens in large numbers are finally taking up the most popular game in the world.Basketball, an American invention increasingly played around the world, these days draws large crowds back home. Likewise, hockey, a game largely imported to the United States from neighboring Canada. Lacrosse, a version of which was played by Native Americans before the Europeans arrived, is also gaining a keen national following.Sports of all kinds are winning support from American armchair enthusiasts from a variety of ethnic backgrounds.1.Which of the following cat reflect the ever-changing ethnic structure of America?2.Who play professional football in the United States?3.What is America’s favorite game?4.Which of the following statements about soccer is true?5.The author of the passage wants to tell us that (  ).

Perhaps only a small boy training to be a wizard at the Hog warts school of magic could cast a spell so powerful as to create the biggest book launch ever. Wherever in the world the clock strikes midnight on June 20th, his followers will flock to get their paws on one of more than 10m copies of’’Harry Potter and the Order of the Phoenix". Bookshops will open in the middle of the night and delivery firms are drafting in extra staff and bleater trucks. Relaxed toys, games, DVDs and other merchandise will be everywhere. There will be no escaping Pottennania.Yet Mr. Potter’s world is a curious one, in which things are often not what they appear. While an excitable media (hereby including The Economist, happy to support such a fine example of globalization) is helping to hype the launch of J.K. Rowling's fifth novel about the most adventurous thing that the publishers (Scholastic in America and Britain's Bloomsbury in English elsewhere) have organized is a reading by Ms. Rowling in London's Royal Albert Hail, to be broadcast as a Jive webcast. Hollywood, which owns everything else to do with Harry Potter, says it is doing even less. Incredible as it may seem, the guardians of the brand say that, to protect the Potter franchise, they are trying to maintain a low profile. Well, relatively low.Ms Rowling signed a contract in 1998 with Warner Brothers, part of AOL Time Warner, giving the studio exclusive film, licensing and merchandising rights in return for what now appears to have been a steal: some $500,000. Warner licenses other firms to produce goods using Harry Potter characters or images, from which Ms Rowling gets a big enough cut that she is now wealthier than the queen-if you believe Britain’s Sunday Times rich list. The process is self generating: each book sets the stage for a film, which boosts book sales, which lifts sales of Potter products.Globally, the first four Harry Potter books have sold some 200m copies in 55 languages; the two movies have grossed over $1.8 billion at the box office. This is a stunning success by any measure, especially as Ms Rowling has long demanded that Harry Potter should not be over commercialized, in line with her wishes, Warner says it is being extraordinarily careful, at least by Hollywood standards, about what it licenses and to whom. It imposed tough conditions on Coca Cola, insisting that no Harry Potter images should appear on cans, and is now in the process of making its licensing programme even more restrictive. Coke may soon be considered too mass market to carry the brand at all.The deal with Warner ties much of the merchandising to the films alone. There are no officially sanctioned products relating to "Order of the Phoenix"; nor yet for "Harry Potter and Prisoner of Azkaban", the film of the third book, which is due out in June 2004. Warner agrees that Ms Rowling’s creation is a different sort of commercial property, one with long-term potential that could be damaged by a typical Hollywood marketing blitz, says Diane Nelson, the studio’s global brand manager for Harry Potter. It is vital, she adds, that with more to come, readers of the bocks are not alienated. "The evidence from our market research is that enthusiasm for the properly by fans is not waning."1.When the author says “there will be no escaping Potter mania”,he implies that (  ).2.Ms Rowling’s reading in London’s Royal Albert Hall is mentioned to show  (  ).  3.The author believes that (  ).  4.Paragraph 4 intends mainly to flow Warner's (  ).  5.It can be concluded from the last paragraph that(  ).

Many objects in daily use have clearly been influenced by science, but their form and function, their dimensions and appearance, were determined by technologists, artisans designers, inventors, and engineers — using nonscientific modes of thought. Many features and qualities of the objects that a technologist thinks about cannot be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process. In the development of Western technology, it has been nonverbal thinking, by and large, that has fixed the outlines and filled in the details of our material surroundings. Pyramids, cathedrals, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them.The creative shaping process of a technologist’s mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of nonverbal thinking on the machine by continually using an intuitive sense of rightness and fitness. What would he the shape of the combustion chamber? Where should the valves be placed? Should it have a long or short piston? Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.Design courses, then, should be an essential element in engineering curricula. Nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed to entail hard thinking, nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools.If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.1.In the text, the author is primarily concerned with (  ).2.It can be inferred that the author thinks engineering curricula are  (  ).  3.Which of the following statements best illustrates the main point of the first two paragraphs of the text?4.Which of the following statements would best serve as an introduction to the text?5.The author cab the predicament faced by the Historic American Engineering Record paradoxical (line 6, paragraph 3) most probably because (  ).

The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihoods of success, making a decision, and only then taking action to implement the decision. Rather, in their day-by-day tactical maneuvers, these senior executives rely on what is vaguely termed intuition to manage a network of interrelated problems that require them to deal with ambiguity, inconsistency, novelty, and surprise; and to integrate action into the process of thinking. Generations of writers on management have recognized that some practicing mangers rely heavily on intuition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse for capriciousness.Isenberg's recent research on the cognitive processes of senior managers reveals that managers’ intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform well-learned behavior patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and hands-on experience that build skills. A third function of intuition is to synthesize isolated bits of data and practice into an integrated picture, often in an Aha! experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally leery of solutions suggested by these methods which run counter to their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to engender a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes familiar patterns.One of the implications of the intuitive style of executive management is that thinking is inseparable from acting. Since managers often know what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is inextricably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert.Given the great uncertainty of many of the management issues that they face, senior managers often instigate a course of action simply to learn more about an issue. They then use the results of the action to develop a more complete understanding of the issue. One implication of thinking/acting cycles is that action is often part of defining the problem, not just of implementing the solution.1.According to the text, senior managers use intuition in all of the following ways except to(  ).2.The text suggests which of the following about the writers on management mentioned in line 1, paragraph 2? 3.It can be referred from the text that which of the following would most probably be one major difference in behavior between Manager X, who uses intuition to reach decisions, and Manager Y, who uses only formal decision analysis?4.The text provides support for which of the following statements?5.Which of the following best describes the organization of the first paragraph of the text?
