单选题Ruth Simmons joined Goldman Sachs's board as an outside director in January 2000: a year later she became president of Brown University. For the rest of the decade she apparently managed both roles without attracting much criticism. But by the end of 2009 Ms. Simmons was under fire for having sat on Goldman's compensation committee; how could she have let those enormous bonus payouts pass unmarked? By February the next year Ms. Simmons had left the board. The position was just taking up too much time, she said. Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm's board. Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with the chief executive's proposals. If the sky, and the share price is falling, outside directors should be able to give advice based on having weathered their own crises. The researchers from Ohio University used a database hat covered more than 10,000 firms and more than 64,000 different directors between 1989 and 2004. Then they simply checked which directors stayed from one proxy statement to the next. The most likely reason for departing a board was age, so the researchers concentrated on those "surprise" disappearances by directors under the age of 70. They found that after a surprise departrue, the probability that the company will subsequently have to restate earnings increased by nearly 20%. The likelihood of being named in a federal class-action lawsuit also increases, and the stock is likely to perform worse. The effect tended to be larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directors are always jumping off a sinking ship. Often they "trade up." Leaving riskier, smaller firms for larger and more stable firms. But the researchers believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news breaks, even if a review of history shows they were on the board at the time any wrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.

单选题 Beijing's top hotels are fielding scores of calls from foreigners and Chinese people eager to book rooms during the 2008 Olympic Games in the Chinese capital. The luxurious and recently-renovated Beijing Hotel said it had received nearly 100 telephone inquiries from people wanting to book rooms during the Games since Beijing won its bid to host the event. "Out of these people, foreigners make up 30 to 40 per cent, including people calling from the United States and Europe," a hotel sales manager surnamed Song said. Minutes before the decision by the International Olympic Committee (IOC) was announced in Moscow, the hotel had already received 50 to 60 such phone calls from would be game-goers gambling on the result. Domestic callers have mainly come from the southern provinces of Guangdong and Fujian. Song said the hotel was not taking reservations, but only noting down names of callers, because seven years was too far in advance. The hotel also may be used by the IOC and would then need to set aside rooms for IOC members, he said. Beijing will have more than 800 hotels with star ratings before the Olympic Games in 2008. The city currently has 20 five-star hotels, 34 four-star hotels and 338 other hotels with lower ratings. About 70 hotels will be designated to accommodate athletes and Olympic officials during the Games.

单选题The Supreme Court's decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering. Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect," a centuries-old moral principle holding that an action having two effects--a good one that is intended and a harmful one that is foreseen--is permissible if the actor intends only the good effect. Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients' pain, even though increasing dosages will eventually kill the patient. Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient medication to control their pain if that might hasten death." George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It's like surgery," he says. "We don't call those deaths homicides because the doctors didn't intend to kill their patients, although they risked their death. If you're a physician, you can risk your patient's suicide as long as you don't intend their suicide." On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying. Just three weeks before the Court's ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the undertreatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care. The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes "systematic patient abuse." He says medical licensing boards "must make it clear...that painful deaths are presumptively ones that are incompetently managed and should result in license suspension./

单选题In the Fall 2006, the National Basketball Association (NBA) started using basketballs made with synthetic, or manmade material instead of leather. They made the switch because they wanted every basketball they use to feel and bounce the same. However, some players complained right away that the new balls bounced differently and were actually harder to control than leather ones. Dallas Mavericks owner Mark Cuban asked for help the Department of Physics at the University of Texas. The scientists investigated friction that affects the ability of a player to hold onto a hall." The greater the friction, the better it will stick to his hand", explains Horwitz, One of the physicists who worked on the project. Tests on both wet and dry balls showed that while the plastic ball was easier to grip when dry, it had less friction and became much harder to hold onto when wet. That"s because sweating stays on the surface of the synthetic balls but gets absorbed into the leather balls—an important detail for sweaty athletes. In January, the NBA went back to using the traditional leather balls. They aren"t perfect, but for now, that"s just the way the ball bounces.

单选题Passage 10 It is a well-known fact that there are constant conflicts among different groups of people, and that people tend to blame their misfortunes on some outside other groups for their misfortunes. What are the causes of group prejudice? There seems to be little doubt that one of the principal causes of prejudice is fear: in particular the fear that the interests of our own group are going to be endangered by the actions of another. This is less likely to be the case in a stable, relatively unchanging society in which the members of different social and occupational groups know what to expect of each other, and know what to expect for themselves. In times of rapid social and economic change, however, new occupations and new social roles appear, and people start looking jealously at each other to see whether their own group is being left behind. Once prejudice develops, it is hard to stop, because there are often social forces at work which actively encourage unfounded attitudes of hostility and fear towards other groups. One such force is education: we all know that children can be taught history in such a way as to perpetuate old hatreds and old prejudices between racial and political groups. Another social influence that has to be reckoned with is the pressure of public opinion. People often think and act differently in groups from the way that they would do as individuals; it takes a considerable effort of will, and often calls for great courage, to stand out against one's fellows and insist they are wrong. Why is it that we hear so much more about the failures of relationships between communities than we do about the successes? I am afraid it is partly due to the increase in communications which radio, television and the popular press have brought about. In those countries where the media of mass communication are commercial enterprises, they tend to measure success by the size of their audience; and people are more likely to buy a newspaper, for instance, if their attention is caught by something dramatic, something sensational, or something that arouses their anxiety. The popular press flourishes on "scare headlines", and popular orators, especially if they are politicians addressing a relatively unsophisticated audience, know that the best way to arouse such an audience is to frighten them. Where there is a real or imaginary threat to economic security, this is especially likely to inflame group prejudice. It is important to remember economic factors if we wish to lessen group prejudice, because unless they are dealt with squarely it will be little use simply persuading people not to be prejudiced against other groups whom they see as their rivals, if not their enemies.

单选题 A good modern newspaper is an extraordinary piece of reading. It is remarkable first for what it contains: the range of news from local crime to international politics, from sport to business to fashion to science, and the range of comment and special features (特定) as well, from editorial page to feature articles and interviews to criticism of books, art, theatre and music. A newspaper is even more remarkable for the way one reads it: never completely, never straight through, but always by jumping from here to there, in and out, glancing at one piece, reading another article all the way through, reading just a few paragraphs of the next. A good modern newspaper offers a variety to attract many different readers, but far more than any one reader is interesied in. What brings this variety together in one place is its topicality (时事性), its immediate relation to what is happening in your world and your locality now. But immediacy and the speed of production that goes with it mean also that much of what appears in a newspaper has no more than transient (短暂的) value. For all these reasons, no two people really read the same paper: what each person does is to put together out of the pages of that day's paper, his own selection and sequence, his own newspaper. For all these reasons, reading newspapers efficiently, which means getting what you want from them without missing things you need but without wasting time, demands skill and self-awareness as you modify and apply the techniques of reading.
