单选题Prolonging Human Life Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people five on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, they must often "go on welfare" if they have a serious illness. When older people become senile or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply " dumping grounds" for the dying in which "care" is given by poorly paid, overworked, and underskilled personnel.

单选题{{B}}第三篇{{/B}} If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercises-and as a result, we are ageing unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect(智能)and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties〈功能〉.) Contraction of front and side parts-as cells die off was observed in some subjects in their thirties, but it was still not evident in some sixty and seventy-year-olds. Matsuzawa's concluded from his tests that there is a simple remedy to the contraction normally associated with age-using the head. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government officers are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant. Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to maintain good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."

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. The Lung Association says parents should take time to talk to their (51) and explain the facts about SARS and how to avoid the illness. The following is based on recommendations (52) Thursday by the Lung Association: ▲ Ask your children if they have heard (53) SARS at school, from friends, from TV, etc. Finding out what they already know can be a good (54) to start the conversation and to clear away any wrong ideas they might have about the illness and how it is spread. ▲ School age children are usually old (55) to understand concepts such as getting sick from germs (细菌) and how to avoid illness. A simple reminder (提示) (56) to cough on people and to wash their hands often may be sufficient for younger kids. All children should be shown how to (57) their hands properly. ▲ Remember to keep it simple so (58) not to overwhelm children with information, but answer them truthfully. Kids can tell when you're not being honest or if you're hiding something, and sometimes the unknown can be more frightening than the (59) . Parents with anxious children will know (60) their kids will handle information on SARS and can tailor their discussion accordingly. ▲ One way to explain the illness is to tell children that SARS is like a bad breathing problem. It is (61) from a cold, but people can catch it in the same ways--such as coughing on someone, not washing your hands or sharing a glass with a sick person. ▲ Describe how SARS is spread, but mention that the chance of (62) SARS is small. There is no reason to tell children people are dying of SARS (63) they ask. Never use the threat of death as a way to remind kids to wash their hands. ▲ Children should be (64) to trust their parents and other caregivers. Explain that many smart people, (65) doctors and scientists, are working on the problem and looking out for everyone's health.
