单选题Some Americans are a little nervous about the nation's future, but others feel secure, knowing that the man they consider the most powerful person in the world isn't going anywhere. Just who is this behind-the-scenes guy they think has more power than George W. Bush ever will? He's Alan Greenspan, a 74-year-old expert economist who heads the Federal Reserve, commonly known as the Fed. Unlike the president, who has to please the voters and compromise with Congress, Greenspan doesn't have to answer to anyone. But that doesn't mean his job is easy. Basically, Greenspan is in charge of keeping the nation's economy stable. The economy is sort of like a balloon: blow in too much air, and it pops. But with too little air, it falls to the floor. Greenspan helps decide when to blow more air into the economy. In this case, the air in a balloon is the amount of money in the economy. Greenspan can make the economy grow by increasing the money supply, or keep the economy from inflating too much by decreasing the money supply. His goal is for the economy to grow and contract gradually. Rapid changes can harm businesses and consumers. After years of very nigh growth, the American economy is starting to slow down. Recently, corporations have been making less money and people are starting to have a harder time finding jobs. Greenspan is hoping to ease the economy into a soft landing. It's just like to make the car come to a gentle stop instead of hitting a brick wall. If he succeeds, the country will avoid two possible problems: rising prices and high unemployment. At the Fed's meeting, Greenspan and the other members decided that the economy was growing at an OK rate, but that there is a possibility of a serious slowdown, and in order to solve that, they could lower interest rates at the next meeting in an attempt to encourage people to borrow and spend. While there's no way to know what they will decide, one thing is certain: the decisions that Greenspan and the Federal Reserve Board make will affect everyone who earns, borrows or spends money.

单选题Darwin's great work, the origin of Species, is now generally accepted as one of the most important books ever written. But when it first came out in 1859, it was both derided and bitterly condemned by scientists and laymen. Much of opposition to the origin of Species arose from Darwin's claim that all living creatures, including man, are somehow related. Many people were outraged by the suggestion that man shared a common ancestor with animals such as apes and monkeys. They attacked Darwin for saying that man had descended from the apes. But Darwin never actually said this. He believed that modem men and modem apes have both descended from the same ancestor. But at some time in pre-history, millions of years ago, men and apes began to develop separately, and ever since have continued to take on different characteristics. Today, more than 90 years after Darwin% death, this is the opinion which scientists continue to hold. In his works, Darwin described the progression of life from its earliest forms. First came the invertebrate-creatures without a backbone. Then invertebrates evolved into fish; fish into amphibians; amphibians into reptiles; and reptiles into birds and mammals. Fossil remains found after his death show that Darwin was right. Perhaps the most amazing fact about his theory is that he managed to work it out with the aid of only a few fossil discoveries. Fossil remains were not the only information which we now possess but which Darwin lacked. He did not know that apes have the same diseases as men; nor that they and men have the same kind of blood. Nor did he know about the modern uses of radiation which enable scientists to tell the age of fossil remains and so estimate the speed at which evolution has taken place.

单选题The decline in moral standards-which has long concerned social analysts--has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad. The fact the ordinary citizens are now starting to think seriously about the nation's moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it. But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. "The thought that 'I'm in it for me' has become deeply rooted in the national consciousness," Ms. Elshtain says. Some of this can be attributed to the disintegration of traditional communities, in which neighbors looked out for one another, she says. With today's greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on serf. In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the US. And Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers. The desire for a higher moral standard is not a lament(挽歌) for some nonexistent "golden age", Elshtain says, nor is it a wishful(一厢情愿) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor the lessening of prejudice. Moral decline will not be reversed until people find ways to counter the materialism in society, she says. "Slowly, you recognize that the things that matter are those that cant' be bought. " As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach(说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.

单选题{{B}}Passage Two{{/B}}{{B}}Questions 62 to 66 are based on the following passage.{{/B}} A scientific panel convened by the World Health organization recommended guidelines on Friday for doctors conducting clinical studies of SARS patients. The panel urged doctors to apply the guidelines in analyzing the masses of potentially useful information about various therapies that were collected in this year’s epidemic. Much of that information has not been published or analyzed. "It is a matter of urgency to get better analysis and review," said Dr. Simon Mardel, a WHO official who led the two-day meeting that ended on Friday. He said thousands of potential therapies and compounds had been tested so far as researchers try to determine treatments for SARS, or severe acute respiratory syndrome. "We recognize that having no treatment for SARS is hindering our ability to control an epidemic in so many ways." He said. In the epidemic earlier this year, various treatments, like drugs to fight the virus or strengthen the immune system, as well as traditional Chinese medicine, were delivered under emergency conditions, in widely different settings and countries to patients suffering from varying stages of the illness. Those conditions--generally without standardized measurements or controlled situations-- have made it hard to interpret results. Standard supportive therapy like nursing, and in severe cases the use of mechanical respirators (呼吸器) to help patients breathe, is the mainstay (主要支持) of SARS care, and helped many patients survive. But doctors still do not know how best to treat SARS patients who have breathing difficulties, Dr. Mardel said. One method is invasive ventilation. A second method involves blowing oxygen into the lungs through a mask. Both carry the risk of transmitting the virus to hospital employees. Without proper analysis, the panel was unable to say definitively which treatment worked best, or which caused the most harm. "There is a lack of shared information," Dr. Mardel said, noting that a lot of data have not been published. The panel also agreed on guidelines that would allow doctors to conduct quick and safe clinical trials, a process that generally takes years to complete. The World Health organization, a United Nations agency did not release the guidelines. Dr. Mardel said they were flexible because no one knew where, when and in what setting SARS would return. Experts in many countries have already listed the treatments they want to test, and the health agency is leaving these decisions to individual nations.
