单选题The Threat to Kiribati The people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati. What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth"s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps. If the trend continues, scientists say, many countries will suffer, Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate—they would be swallowed by the sea. The loss of these coral islands would be everyone"s loss. Coral formations are home to more species than any other place on earth. The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don"t have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.

单选题{{B}}第二篇{{/B}} Pain is easier to endure if you know you can end it. Speakers at a session on pain at the British Association's psychology section have new evidence to support this idea for two common experiences of pain: in childbirth and at the dentist's. On the other side of the coin, their inability to control pain may explain why some people with continual pain have psychological problems as well. Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug. J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch. Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain. By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too. Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense."

单选题 Talking to Kids about SARS (非典) School age children may be learning about SARS from adults and the media, but may not know what to make of the situation, says a national health charity.

单选题 The Workers' Role in Management Traditionally, it has been the workers' role to work and management's role to manage. Managers have planned and directed the firm's operations with little thought to consulting the labor force. Managers have rarely felt compelled to obtain the workers' opinions or to explain their decisions to their employees. At most, companies have provided "suggestion boxes" in which workers could place ideas for improving procedures. In recent years, however, many management specialists have been arguing that workers are more than sellers of labor—they have a vital stake in the company and may be able to make significant contributions to its management. Furthermore, major company decisions profoundly affect workers and their dependents. This is particularly true of plant closings, which may put thousands on the unemployment lines. Should workers, then, play a stronger role in management? Workers should have a role in management. At the very least, the labor force should be informed of major policy decisions (A common complaint among rank-and-file workers is the lack of information about company policies and actions). Between 1980 and 1985 about five million workers were the victims of plant closings and permanent layoffs, often with no warning. At least 90 days' notice ought to be given in such instances so that workers have time to adjust. Management should consult workers before closing a plant, because the workers might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions that will help keep the plant operating. It should become a general practice to include workers in some managerial decision makings. There ought to be representatives of the workers on the firm's board of directors or other major policy making groups. If rank-and-file workers are given a voice in the planning and management of the work flow, they will help to make improvements, their morale will rise, and their productivity will increase. As a further incentive, they must be given a share in the company's profits. This can be done through employee stockownership plans, bonuses, or rewards for efficiency and productivity. Finally, when a plant can no longer operate at a profit, the workers should be given the opportunity to purchase the plant and run it themselves.

单选题The Iceman On a September day in 1991, two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, or 3,200 meters), the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface. It was lying face downward. The skeleton (骨架) was in perfect condition, except for a wound in the head. There was still skin on the bones and the remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots. Nearby was a pair of gloves made of tree bark (树皮) and a holder for arrows. Who was this man? How and when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old. With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B. C. , he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story. A new kind of X-ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, or he may have been fighting bandits. He may even have been a bandit himself. By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has given us important clues to the history of those distant times.
