单选题Attitudes to AIDS Now Most people say that the USA is making progress in fighting AIDS. But they don't know there's no cure and strongly disagree that "the AIDS epidemic is over." The findings, released Thursday by the Kaiser Family Foundation, reassure activists who have worried that public concern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths. "While people are very optimistic about the advances, they're still realistic about the fact that there is no cure," says Sophia Chang, director of HIV programs at the foundation. The Kaiser survey, like a recent USA today Gallup Poll, does find that the number of people ranking AIDS as the country's top health problem has fallen. In the Kaiser poll, 38% say it's the top concern, down from 44 % in a 1996 poll; in the Gallup Poll, 29 % say AIDS is N0.1, down from I 41% in 1992and67% in 1987. Other findings from Kaiser, which polled more than 1,200 adults in September and October and asked additional questions of another 1,000 adults in November.. 52% say the country is making progress against AIDS; up from 32% in 1995. 51% say the government spends too little on AIDS. 86 % correctly say AIDS drugs can now lengthen lives: an equal number correctly say that the drugs are not cures. 67% incorrectly say that AIDS deaths increased or stayed the same in the past year; 24% know deaths fell. Daniel Zingale, director of AIDS Action Council, says, "I'm encouraged that the American people are getting the message that the AIDS epidemic isn't over. I hope the decision-makers in Washington are getting the same message...We have seen signs of complacency." Epidemic n.流行病; (流行病的)流行,传播 Reassure vt.向.......一再保证,安慰,使放心,使消除疑虑.

This incident aroused anxiety about the threat posed by foreign residents from nations hostile to the United States. Six people died in the bomb, which caused an estimated $600 million in property and other economic damage. Trials that followed sentenced six people of carrying out the attack. In addition to foreign-sponsored terrorism, the United States has an abundant history of domestic terrorism. Early in the 20th century, labour leaders such as William Dudley openly supported a philosophy of revolutionary violence. In the late 1960s and early 1970s, during the latter stages of the U.S. involvement in the Vietnam War, some terrorist groups bombed buildings on university campuses throughout the country and at corporation headquarters and government buildings in New York City. Between 1978 and 1995, a terrorist known as the Unabomber planted or mailed homemade bombs that killed 3 people and wounded 23 others in 16 separate incidents throughout the United States. The Unabomber, who claimed an agreement with radical environmentalists and others opposed to the effects of industrialization and technology, targeted university professors, corporate executives, and computer merchants. In April 1996 federal agents arrested Theodore Kaczynski, a suspect they thought to be the Unabomber. Kaczynski, a Harvard-educated former math professor, admitted his guilty to 13 federal charges in 1998 in exchange for agreement that prosecutors would not request the death penalty during sentencing. The court sentenced Kazynski to four life terms plus 30 years and ordered him to pay $15 million in compensation. In April 1995 a truck bomb exploded in front of the Federal Building in Oklahoma City, killing 168 people and injuring more than 500, making it one of the deadliest terrorist attacks in United States history. Federal agents arrested two men McVeigh and Nichols, who belonged to an extremist group advocating resistance to national laws and political institutions. In June 1997 McVeigh was found guilty of murder in connection with the bombing and sentenced to death. Later in the year Nichols was convicted of the less severe charges of manslaughter and conspiracy, and he was sentenced to life in prison in June 1998. McVeigh was executed in 2001.

单选题 Stress Level Tied to Education Level People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior. However, the study also found that when less-educated people did suffer stress it was more severe and had a larger impact on their health. From this, researchers have concluded that the day-to-day factors that cause stress are not random. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them. The research team interviewed a national sample of 1,031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time. "Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health," lead researcher Dr. Joseph Grzywacz, of Wake Forest University Baptist Medical Center, said in a prepared statement. "The downward turns in health were connected with daily stressors and the effect of daily stressors on their health is much more devastating for the less advantaged." Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic. "If something happens every day, maybe it's not seen as a stressor," Grzywacz says. "Maybe it is just life."

单选题A Gay Biologist Molecular biologist Dean Hamer has blue eyes, light brown hair and a good sense of humor. He smokes cigarettes, spends long hours in an old laboratory at the US National Institute of Health, and in his free time climbs up cliffs and points his skis down steep slopes. He also happens to be openly, matter of factly gay. What is it that makes Hamer who he is? What, for that matter, accounts for the talents and traits that make up anyone"s personality? Hamer is not content merely to ask such questions; he is trying to answer them as well. A pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. To a remarkable extent, his work on what might be called the gay, thrill-seeking and quit-smoking genes reflects how own genetic predispositions. That work, which has appeared mostly in scientific journals, has been gathered into an accessible and quite readable form in Hamer"s creative new book, Living with Our Genes. "You have about as much choice in some aspect of your personality." Hamer and co-author Peter Copeland write in the introductory chapter, "as you do in the shape of your nose or the size of your feet." Until recently, research into behavioral genetics was dominated by psychiatrists and psychologists, who based their most compelling conclusions about the importance of genes on studies of identical twins. For example, psychologist Michael Bailey of Northwestern University famously demonstrated that if one identical twin is gay, there is about a 50% likelihood that the other will be too. Seven years ago, Hamer picked up where the twin studies left off, homing in on specific strips of DNA that appear to influence everything from mood to sexual orientation. Hamer switched to behavioral genetics from basic research, after receiving his doctorate from Harvard, he spent more than a decade studying the biochemistry of a protein that cells use to metabolize heavy metals like copper and zinc. As he was about to turn 40, however, Hamer suddenly realized he had learned as much about the protein as he cared to. "Frankly, I was bored," he remembers, "and ready for something new." Homosexual behavior, in particular, seemed ripe for exploration because few scientists had dared tackle such an emotionally and politically charged subject. "I"m gay," Hamer says with a shrug, "but that was not a major motivation. It was more of a question of intellectual curiosity—and the fact that no one else was doing this sort of research."

George liked his job and he liked the town he lived in, but his wife kept telling him that his pay was not enough to meet the needs of the family. That was why he was thinking of taking a job in Birmingham, a nearby city about 50 miles away. He had been offered a job in a factory there, and the pay was far better. George lived in Wyeford, a medium-sized town. He really liked the place and didn't like the idea of moving somewhere else, but if he took the job in Birmingham, he would have to move his family there. Henry Manley was the manager of a small company manufacturing .electric motors. The company was in deep trouble because, among other reasons, the Japanese were selling such things at very low prices. As a result, Manley had to cut his own prices and profits as well. Otherwise he would not get any orders at all. Even then, orders were still not coming in fast enough, so that there was no money for raises (加工资) for his workers. Somehow, he had to struggle along and keep his best workers as well. He sighed. Just then the phone rang. His secretary told him that George Strong wanted to see him as soon as possible. Manley sighed again. He could guess what it was about. George Strong was a very young engineer. The company had no future unless it could attract and keep men like him. Manley rubbed his forehead (前额); his problems seemed endless.

Experts on dyslexia say that the problem is not a disease. They say that persons with dyslexia use information in a different way. One of the world's great thinkers and scientists Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventor Thomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 years ago. Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled. The doctors found that the brains of persons with dyslexia arc different. In most people, the left side of the brain—the part that controls language—is larger than the right side. In persons with dyslexia, the right side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males than in females, and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby's body long before it is born. They are trying to find ways to teach persons with dyslexia Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent or creative.

单选题 第二篇 How does Science Proceed? How exactly does science work? How do scientists go about "doing" science? Ordinarily we think science proceeds in a straightforward way. Ideally, scientists make observations, formulate hypotheses, and test those hypotheses by making further observations. When there is difference between what is observed and what is predicted by the hypothesis, the hypothesis is reviewed. Science proceeds in this way, which is a gradual method of finding the best fit between observation and prediction. But this idealized version of how one "does" science is naive. Although science demands proof that observations made by one observer be observable by other observers using the same methods. It is by no means clear that even when confronted with identical phenomena different observers will report identical observations. And it is most certain that, even if the same observations are made, the conclusions as to the meaning of the observations frequently differ. The fact is that all of us scientists included, see differently. Variations in human perception are well known and have been studied extensively. Distortions in perceptions are frequently seen among observers, even though they may be in identical settings viewing identical phenomena. A documented misperception from history can be found in the experience of Darwin. His ship, Beagle, after anchoring off the Patagonian coast, sent off a landing party in small rowboats. Amazingly, the Patagonian natives watching from shore were blind to the Beagle, but could easily see the tiny rowboats. They have no prior experience of huge sailing ships, but small rowing vessels were an everyday part of their life. Rowboats fit their model of the world but huge ships did not. Their model determined their perceptions. Our ideas that science proceeds on an utterly objective and straightforward basis ignores the distortions of reality imposed by our own perceptual apparatus. In many cases we see what we have been trained to see, what we are used to seeing. If a subject is fitted with special glasses that are designed to invert the visual field, at first the subject sees everything upside down. After a period of time, as the glasses continue to be worn, a correction is made by our perceptual mechanism and the image is flipped, so that the world once again appears erect.

单选题A New Doctors' Dilemma When Christian Barnard, a South African doctor, performed the first human heart transplant in 1967, the result was a worldwide moral debate on the ethics of transplanting organs. Hearts were not the first human organs to be transplanted but, in this case, if a donor gave his or her heart, he or she would obviously and necessarily die (or be dead). Kidney transplants, which were already quite common in 1967, often involved the transfer of a single kidney from a close living relative. The chances of survival of the donor were somewhat diminished because he now had only one kidney and if that kidney were affected by disease, he would not have a healthy kidney in reserve. Nevertheless, the donor would certainly not necessarily die. Undoubtedly, another reason why the first heart transplant was so controversial was the fact that we associate so many personality traits with the heart. Questions were asked of the type: '"If a person had a different heart, would he still be the same person?", or "If doctors needed a dying person's heart, would they tend to declare him dead prematurely?", and so on. Today, not only hearts and kidneys, but also such extremely delicate organs as lungs and livers. are transplanted. These developments have led to a far higher or proportion of successful operations and this, in turn, has led to greater demand for transplants. At the same time, many of the original moral questions surrounding heart transplants have been almost forgotten. However, as a result of the heavy demand for organs, a new moral dilemma has emerged. For example, in the United States there are many people who would survive if lungs were available for transplanting. In fact, about 80% of them die before a suitable donor is found. In these circumstances who would decide if a donor were found whose lungs were equally suitable for two potential recipients? This problem is made worse by the fact that many patients, or their families, become desperate to find a donor. Some succeed in publicizing their situation in newspapers, to politicians or on television. Sometimes, as a result, suitable donors are found. But what would happen if another patient needed the organ more than the one who got the publicity? Who would decide if the other patient should get the organ? Would it be the doctors? Or the donor? Or the family who got the publicity? If such a dilemma developed it would be very difficult to resolve and it would be a matter of life or death to the patients involved.
