单选题 On an average of six times a day, a doctor in Holland practices " active" euthanasia:intentionally administering a lethal (致死的) drug to a terminally ill patient who has asked to berelieved of suffering. Twenty times a day, life-prolonging treatment is withheld or withdrawn whenthere is no hope that it can effect an ultimate cure. "Active" euthanasia remains a crime on theDutch statute books, punishable by 12 years in prison. But a series of court cases over the past 15years has macle it clear that a competent physician who carries it out will not be prosecuted. Euthanasia, often called "mercy killing", is a crime everywhere in Western Europe. Butmore and more doctors and nurses readily admit to practicing it, most often in the "passive"form of withholding or withdrawing treatment. The long simmering euthanasia issue has latelyboiled over into a sometimes fierce public debate, with both sides claiming the mantle of ultimaterighteousness. Those opposed to the practice see themselves upholding sacred principles of respectfor life, while those in favor raise the banner of humane treatment. After years on the defensive,the advocates now seem to be gaining ground. Recent polls in Britain show that 72 percent ofBritish subjects favor euthanasia in some circumstances. An astonishing 76 percent of respondentsto a poll taken last year in France said they would like the law changed to decriminalize mercykillings. Euthanasia has been a topic of controversy in Europe since at least 1936, when a bill wasintroduced in the House of Lords that would have legalized mercy killing under very tightlysupervised conditions. That bill failed, as have three others introduced in the House of Lords sincethen. Reasons for the latest surge of interest in euthanasia are not hard to find. Europeans, likeAmericans, are now living longer. Therefore, lingering chronic diseases have replaced criticalillnesses as the primary cause of death. And the euthanasists argue that every human being shouldhave the right to "die with dignity", by which they usually mean the right to escape the horrors ofa painful or degrading hospitalization (住院治疗) . Most experts believe that euthanasia will continue to be practiced no matter what the law says.

单选题Some houses are designed to be smart. Others have smart designs. An example of the second type of house won an Award of Excellence from the American Institute of Architects. Located on the shore of Sullivan's Island off the coast of South Carolina, the award-winning cube- shaped beach house was built to replace one smashed to pieces by Hurricane Hugo 10 years ago. In September 1989, Hugo struck South Carolina, killing 18 people and damaging or destroying 36000 homes in the state. Before Hugo, many new houses built along South Carolina's shoreline were poorly constructed, and enforcement of building codes wasn't strict, according to architect Ray Huff, who created the cleverly-designed beach house. In Hugo's wake, all new shoreline houses are required to meet stricter, better-enforced codes. The new beach house on Sullivan's Island should be able to withstand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour. At first sight, the house on Sullivan's Island looks anything but hurricane-proof. Its redwood shell makes it resemble "a large party lantern" at night, according to one observer. But looks can be deceiving. The house's wooden frame is reinforced with long steel rods to give it extra strength. To further protect the house from hurricane damage, Huff raised it 2.7 meters off the ground on timber pilings—long, slender columns of wood anchored deep in the sand. Pilings might appear insecure, but they are strong enough to support the weight of the house. They also elevate the house above storm surges. The pilings allow the surges to run under the house instead of running into it. "These swells of water come ashore at tremendous speeds and cause most of the damage done to beach- front buildings." said Huff. Huff designed the timber pilings to be partially concealed by the house's ground-to-roof shell. "The shell masks the pilings so that the house doesn't look like it's standing with its pant legs pulled up. " said Huff. In the event of a storm surge, the shell should break apart and let the waves rush under the house, the architect explained.

单选题Text 4 Every product on the market has a variety of costs built into it before it is ever put up for sale to a customer. There are costs of production, transportation, storage, advertising, and more. Each of these costs must bring in some profit at each stage: truckers must profit from transporting products, or they would not be in business. Thus, costs also include several layers of profits. The selling price of a product must take all of these costs (and built in profits) into consideration. The selling price itself consists of a markup over the total of all costs, and it is normally based on a percentage of the total cost. The markup may be quite high, 90 percent of cost, or it may be low. Grocery items in a supermarket usually have a low markup, while mink coats have a very high one. High markups, however, do not in themselves guarantee big profits. Profits come from turnover. If an item has a 50 percent markup and does not sell, there is no profit. But if a cereal has an 8 percent markup and sells very well, there are reasonable profits. While most pricing is based on cost factors, there are some exceptions. Prestige pricing means setting prices artificially high in order to attract select clientele. Such pricing attempts to suggest that the quality or style of the product is exceptional or that the item cannot be found elsewhere. Stores can use prestige pricing to attract wealthy shoppers. Leader pricing and bait pricing are the opposites of prestige pricing. Leader pricing means setting low prices on certain items to get people to come into the stores. The products so priced are called loss leaders because little or no profit can be made on them. The profits are made from other products people buy while in the store. Bait pricing, now generally considered illegal, means setting artificially low prices to attract customers. The store, however, has no intention of selling goods at the bait prices. The point is to get people into the store and persuade them of the inferiority of the low priced item. Then a higher priced item is presented as a better alternative. A common retail tactic is odd priced products. For some products of $300, the store will set the price at $295 or $299,95 to give the appearance of a lower price. Automobiles and other high priced products are usually priced in this manner. For some reason $7995 has more appeal to a potential car customer than $8000. Bid pricing is a special kind of price setting. It is often used in the awarding of government contracts. Several companies are asked to submit bids on a job, and normally the lowest bidder wins. A school system may want to buy a large number of computers. Several companies are asked to submit prices, and the school district will decide on the best bid based as well on considerations of quality and service.

单选题Text 2 Recent stories in the newspapers and magazines suggest that teaching and research contradict each other, that research plays too prominent a part in academic promotions, and that teaching is badly underemphasized. There is an element of truth in these statements, but they also ignore deeper and more important relationships. Research experience is an essential element of hiring and promotion at a research university because it is the emphasis on research that distinguishes such a university from an arts college. Some professors, however, neglect teaching for research and that presents a problem. Most research universities reward outstanding teaching, but the greatest recognition is usually given for achievements in research. Part of the reason is the difficulty of judging teaching. A highly responsible and tough professor is usually appreciated by top students who want to be challenged, but disliked by those whose records are less impressive. The mild professor gets overall ratings that are usually high, but there is a sense of disappointment in the part of the best students, exactly those for whom the system should present the greatest challenges. Thus, a university trying to promote professors primarily on the teaching qualities would have to confront this confusion. As modern science moves faster, two forces are exerted on professor: one is the time needed to keep on with the profession; the other is the time needed to teach. The training of new scientists requires outstanding teaching at the research university as well as the arts college. Although scientists are usually "made" in the elementary schools, scientists can be "lost" by poor teaching at the college and graduate school levels. The solution is not to separate teaching and research, but to recognize that the combination is difficult but vital. The title of professor should be given only to those who profess, and it is perhaps time for universities to reserve it for those willing to be an earnest part of the community of scholars. Professors unwilling to teach can be called "distinguished research investigators" or something else. The pace of modern science makes it increasingly difficult to be a great researcher and a great teacher. Yet many are described in just those terms. Those who say we can separate teaching and research simply do not understand the system but those who say the problem will disappear are not fulfilling their responsibilities.

单选题It is easier to negotiate initial salary requirement because once you are inside, the organizational constraints influence wage increases. One thing, however, is certain: your chances of getting the raise you feel you deserve are less if you don't at least ask for it. Men tend to ask for more, and they get more, and this holds true with other resources, not just pay increases. Consider Beth's story: I did not get what I wanted when I did not ask for it. We had cubicle (小隔间 ) offices and window offices. I sat in the cubicles with several male colleagues. One by one they were moved into window offices, while I remained in the cubicles. Several males who were hired after me also went to offices. One in particular told me he was next in line for an office and that it had been part of his negotiations for the job. I guess they thought me content to stay in the cubicles since I did not voice my opinion either way. It would be nice if we all received automatic pay increases equal to our merit, but "nice" isn't a quality attributed to most organizations. If you feel you deserve a significant raise in pay, you'll probably have to ask for it. Performance is your best bargaining chip when you are seeking a raise. You must be able to demonstrate that you deserve a raise. Timing is also a good bargaining chip. If you can give your boss something he or she needs (a new client or a sizable contract, for example) just before merit pay decisions are being made, you are more likely to get the raise you want. Use information as a bargaining chip too. Find out what you are worth on the open market. What will someone else pay for your services? Go into the negotiations prepared to place your chips on the table at the appropriate time and prepared to use communication style to guide the direction of the interaction.

单选题 Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound(只在地球上的)experience in the summer of 1980 when he participated in the NASA-ASEE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point was assigned to the Marshall Space Flight Center's propulsion(推进)lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seal could have led to destructive results for the astronauts who relied on them. "I worked abit with NASA engineers," says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic(热力学的)analysis." At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status. It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1987. Since then he has participated in three space mission. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000. Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes a link with colleges and universities," Voss explains. "There is an exchange of information and an exchange of perspectives that is very important." For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom."
