单选题What is a knowledge worker? Knowledge workers are people who routinely use a computer in their work to enhance their productivity. She or he is the critical component in a computer system. A computer system is made up of people, using data and procedures to work with software and hardware components. It takes all five working together to produce results. Knowledge workers are white-collar professionals from many walks of life who have the following characteristics. They understand how to use a personal computer. They know how to work with computer-based information. They understand how the computer benefits their work and the business. They regard the computer as a productivity tool. Knowledge workers may be employed in a company of any size, large or small, at a wide range of tasks. They may be self-employed, working in their own office or at home. They may be sales representatives or managers who travel with a portable computer. Students are knowledge workers as well. Many of you may be preparing for a career in knowledge work in office automation, public relations, account supervision, social work, management, or a number of other occupations. Today, there are over 70 million knowledge workers in the United States, who generate nearly 2 trillion pieces of paper each year. These knowledge workers work 10 hours per week more than they did 10 years ago, and create over 15 billion new pieces of paper a year. According to a survey conducted by Industry Week magazine in 1990, 39 percent of U. S. management-level knowledge workers say paperwork is a problem. Further, USA Today reported in 1991 that the average knowledge worker has 36 hours of work stacked up on the desk. Clearly, the computer as a productivity tool must play an ever more important role in knowledge work and knowledge work itself is steadily assuming larger proportions. According to several worldwide studies, urban centers in Canada, the United States, Europe, and other developed areas are increasingly using computer technology and thus evolving knowledge-based cities. These knowledge-based cities are characterized by. (1) a concentration of scientists and engineers, (2) business, university, and governmental research activities, (3) a high degree of interaction between individuals and the various institutions, and (4) a positive image that attracts college graduates to knowledge work. Clearly, the decade of the 1990s and the new millennium that follows are an exciting time for knowledge work.

单选题 When you are near a lake or a river, you feel cool. Why? The sun makes the earth hot, but it can't make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth rises. Then the cool air over the water moves in and takes the place of the hot air. Then you feel the cool air and the wind, which makes you cool. Of course, scientists can't answer all of your questions. If we ask, "Why is the ocean full of salt?" scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into the cracks. The rain then carries the salt into he earth and into the rivers. The rivers carry the salt into the ocean. But then we ask, "What happens to the salt in the ocean? The ocean doesn't get more slat every year." Scientists are not sure about the answer to this question. We know a lot about our world. But there are still many answers that we do not have, and we are curious.

Mark your answers on ANSWER SHEET 1. {{B}}Text 1{{/B}} That low moaning sound in the background just might be the Founding Fathers protesting from beyond the grave. They have been doing it when George Bush, at a breakfast of religious leaders, scorched the Democrats for failing to mention God in their platform and declaimed that a President needs to believe in the Almighty. What about the constitutional ban on "religious test(s)" for public office? the Founding Fathers would want to know. What about Tom Jefferson's conviction that it is Possible for a nonbeliever to be a moral person, "find (ing) incitements to virtue in the comfort and pleasantness you feel in its exercise"? Even George Washington must shudder in his sleep to hear the constant emphasis on "Judeo- Christian values." It was he who wrote, "We have abundant reason to rejoice that in this Land ... every person may here worship God according to the dictates of his own heart." George Bush should know better than to encourage the theocratic ambitions of the Christian right. The "wall of separation" the Founding Fathers built between church and state is one of the best defenses freedom has ever had. Or have we already forgotten why the Founding Fathers put it up? They had seen enough religious intolerance in the colonies: {{U}}Quaker women{{/U}} were burned at the stake in Puritan Massachusetts; Virginians could be jailed for denying the Bible's authority. No wonder John Adams once described the Judeo-Christian tradition as "the most bloody religion that ever existed," and that the Founding Fathers took such pains to keep the hand that holds the musket separate from the one that carries the cross. There was another reason for the separation of church and state, which no amount of pious ranting can expunge: not all the Founding Fathers believed in the same God, or in any God at all. Jefferson was a renowned doubter, urging his nephew to "question with boldness even the existence of a God." John Adams was at least a skeptic, as were of course the revolutionary firebrands Tom Paine and Ethan Allen. Naturally, they designed a republic in which they themselves would have a place. Yet another reason argues for the separation of church and state. If the Founding Fathers had one overarching aim, it was to limit the power not of the churches but of the state. They were deeply concerned, as Adams wrote, that "government shall be considered as having in it nothing more mysterious or divine than other arts or sciences." Surely the Republicans, committed as they are to "limited government," ought to honor the secular spirit that has limited our government from the moment of its birth.

单选题Auctions (拍卖) are public sales of goods, made by an officially approved auctioneer. He asked the crowd assembled in the auction room to make offers, or bids, for the various items on sale. He encouraged buyers to bid higher figures, and finally named the highest bidder as the buyer of the goods. This is called "knocking down" the goods, for the bidding ends when the auctioneer bangs a small hammer on a table at which he stands. This is often set on a raised platform called a rostrum. The ancient Romans probably invented sales by auction, and the English word comes from the Latin auction, meaning "increase". The Romans usually sold in this way the spoils taken in war, these sales were called "sub hash", meaning "under the spear", a spear being stuck in the ground as a signal for a crowd to gather. In England in the eighteenth century, goods were often sold "by the candle": a short candle was lit by the auctioneer, and bids could be made while it stayed alight. Practically all goods whose qualities varied are sold by auction. Among these are coffee, hides, skins, wool, tea, cocoa, furs, spices, fruit, vegetables and wines. Auction sales are also usual for land and property, antique furniture, pictures, rare books, old china and similar works of art. The auction rooms at Christie's and Sotheby's in London and New York are world famous. An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by prospective buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a "lot", is usually given a number. The auctioneer need not begin with Lot 1 and continue in numerical order; he may wait until he registers the fact that certain dealers are in the room and then produce the lots they are likely to be interested in. The auctioneer's services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible.

单选题The House is expected to pass a piece of legislation Thursday that seeks to significantly rebalance the playing field for unions and employers and could possibly reverse decades of declining membership among private industries. The Employee Free Choice Act would allow a union to be recognized after collecting a majority of vote cards, instead of waiting for the National Labor Relations Board to oversee a secret ballot election, which can occur more than 50 days after the card vote is completed. Representatives of business on Capitol Hill oppose the bill. The National Association of Manufacturers, The National Federation of Independent Business, the U.S. Chamber of Commerce and other business groups oppose the shift away from secret ballots saying the change could threaten the privacy of the workers. "This isn't about preventing increased unionization, it's about protecting rights," said the National Association of Manufacturer's Jason Straczewski, of his organization's opposition to bill. Straczewski says eliminating the secret-ballot step would open up employees to coercion (强迫,胁迫) from unions. Samuel of the AFL-CIO contends the real coercion comes from employers. "Workers talking to workers are equals while managers talking to workers aren't," Samuel said. He cites the 31,358 cases of illegal employer discrimination acted on by the National Labor Relations Board in 2005. Samuel also points out that counter to claims from the business lobby, the secret ballot would not be eliminated. The change would only take the control of the timing of the election out of the hands of the employers. "On the ground, the difference between having this legislation and not would be the difference between night and day," said Richard Shaw of the Harris County Central Labor Council, who says it would have a tremendous impact on the local level. The bill has other provisions (规定,条款) as well. The Employee Free Choice Act would also impose binding arbitration (仲裁) when a company and a newly formed union cannot agree on a contract after 3 months. An agreement worked out under binding compulsory arbitration would be in effect for 2 years, a fact that Straczewski calls, "borderline unconstitutional". "I don't see how it will benefit employees if they're locked into a contract," said Straczewski. The bill's proponents point to the trend of recognized unions unable to get contracts from unwilling employers. The Federal Mediation and Conciliation Service, the organization that oversees arbitration, reported that in 2004, 45 percent of newly formed unions were denied first contracts by employers. The bill would also strengthen the penalties for companies that illegally coerce or intimidate employees. As it stands, the law on the books hasn't changed substantially since the National Labor Relations Act was made into law in 1935. The NLBR can enforce no other penalty than reinstating wrongfully fired employees or recovering lost wages.

单选题{{B}}Passage Two{{/B}} Concerning money or anything else, conflicts between husband and wife usually reflect a power struggle. Conflicts between parent and child often center around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please, and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent-training courses. Parents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behavior will be whatever the parents consider proper and constructive. But in a society of rapidly changing social and moral values, parents and children often disagree about what is important and what is right. Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels may also concern school work, after school jobs, decisions, use of the family car, dating, and sexual behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents' expectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents' values and ideas. Many parents feel that they get along with their adolescents quite well.

单选题Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of travel in the foreseeable future. The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system. When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements. The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn of his coming exit. It is estimated that an automated highway will be able to carry 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present-day highway.
