单选题 The idea of helping people comes naturally to most of us. If we see a blind person getting off a bus, we watch to make sure that he is in no danger of falling. Members of a family help one another, with particular care for the very young and the elderly. There are many people who have nobody near to see their need for help and often nobody to give it even when the need is known. The old, the handicapped, the homeless and friendless — these are the people for whom help may not come, because nobody sees. It may not have occurred to you that you are in a position to help. Community service means helping the people around you. Organizations exist which try to make sure that someone sees when help is needed and does something about it. These organizations depend on voluntary help to carry out a wide variety of tasks, volunteers giving up a little of their spare time to lend a hand. If you wish to take part in this worthwhile activity, what sort of things would you do? Think of the people most in need of help and the ways in which help can be given. Much of the work of community service is concerned with the care of the elderly and the handicapped. Old people cannot always redecorate their homes. Household repairs, cleaning, preparing food or taking care of the garden may all prove difficult. Elderly people with failing eyesight are delighted if a friend comes in to read or to write letters for them. A helping hand and a friendly face can mean a great deal to a lonely elderly person. Handicapped people may be young or old. People confined to wheelchairs cannot go out unless somebody takes them. Blind children may love swimming but they need a sighted swimmer to go with them. Some handicapped people may be unable to go out at all and a visitor is then more than welcome. Voluntary help is needed in hospitals. There are library and shop trolleys to be taken round the wards and at Christmas time decorations to be put up and parties and concerts to be organized. Some volunteers help to run playgrounds for young children during school holidays and also look after children in preschool play groups. What do you do if you want to help? Your school may have contact with an outside organization or, indeed, run a community service scheme itself. In many towns there is a committee called the Council of Social Service or the Guild of Social Welfare and they will be able to tell you about voluntary activities in the area. The Citizens' Advice Bureau and the Women's Royal Voluntary Service are other sources of information, as is the public library. Churches, the Scouts and other youth organizations can tell you about their activities. Most large cities in the United Kingdom have youth groups for community service, for it is here that the need is greatest. If you join such a group, you will bring pleasure and hope to people who need your help.

单选题{{B}}Passage 3{{/B}} Dr Thomas Starzl, like all the pioneers of organ transplantation, had to learn to live with failure. When he performed the world's first liver transplant 25 years ago, the patient, a three-year-old boy, died on the operating table. The next four patients didn't live long enough to get out of the hospital. But more determined than discouraged, Starzl and his colleagues went back to their lab at the University of Colorado Medical School.They devised techniques to reduce the heavy bleeding during surgery, and they worked on better ways to pre- vent the recipient's immune system from rejecting the organ — an ever-present risk. But the triumphs of the transplant surgeons have created yet another tragic problem: a severe shortage of donor organs. "As the results get better, more people go on the waiting lists and there's wider disparity between supply and need," says one doctor. The American Council on Transplantation estimated that on any given day 15 000 Americans are waiting for organs. There is no shortage of actual organs; each year about 5 000 healthy people die unexpectedly in the United States, usually in accidents. The problem is that fewer than 20 percent become donors. This trend persists despite laws designed to encourage organ recycling. Under the federal Uniform Anatomical Gift Act, a person can authorize the use of his organs after death by signing a statement. Legally, the next of kin can veto these posthumous gifts, but surveys indicate that 70 to 80 percent of the public would not interfere with a family member's decision. The biggest roadblock, according to some experts, is that physicians don't ask for donations, either because they fear offending grieving survivors or because they still regard some transplant procedures as experimental. When there aren't enough organs to go around, distributing the available ones becomes a matter of deciding who will live and who will die. Once donors and potential recipients have been matched for body size and blood type, the sickest patients customarily go to the top of the local waiting list. Beyond the seriousness of the patients' condition, doctors base their choice on such criteria as the length of time the patient has been waiting, how long it will take to obtain an organ and whether the transplant team can gear up in time.

单选题Many phrases used to describe monetary policy, such as "steering the economy to a soft landing" or "a touch on the brakes", makes it sound like a precise science. Nothing could be further from the truth. The relation between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likes the conduct of monetary policy to driving a car with a blackened windscreen, a cracked rearview mirror and a faulty steering wheel. Given all these disadvantages, central bankers seem to have had much to boast about. Average inflation in the big seven industrial economies fell to a mere 2.3% last year, close to its lowest level in 30 years, before rising slightly to 2.5% this July. This is a long way below the double-dig- it rates which many countries experienced in the 1970s and early 1980s. It is also less than most forecasters has predicted. In late 1994 the panel of economists which The Economist polls each month said that America"s inflation rate would average 3.5% in 1995. In fact, it fell to 2.6% in August, and is expected to average only about 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point below the rate predicted at the end of last year. This is no flash in the pan; over the past few years, inflation has been continually lower than expected in Britain and America. Economists have been particularly surprised by favourable inflation figures in Britain and the United States, since conventional measures suggest that both economies, and especially that of America, have little productive slack. America"s capacity utilisation, for example, hit historically high levels earlier this year, and its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemployment—the rate below which inflation has taken off in the past. Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful structural changes in the world have up-ended the old economic models which were based upon the historical link between growth and inflation.

单选题 The Type A behavior is characterized by strong ambition, competitiveness, and a sense of time urgency. Type A's tended to be engaged in a perpetual attempt to achieve as much as possible in the least time even though their goals were often unrealistic. Persons With these traits tend to have a significantly high rate of heart problems, and the standard risk factors of smoking and high blood pressure are significantly higher in Type A's. The most extensive attempt to modify Type A behavioral patterns has been carded out in the San Francisco Bay area, where 600 men who have suffered heart attacks are participating in an ongoing study. The treatment consists of a variety of approaches which are intended to modify both the perception of stress and the reaction to stress. Subjects have been taught to observe their own behavior to change and manage their thinking a bout once-stressful occurrences, making them neutral by interpreting them in ways that do not evoke stress. Thus instead of fuming about the time they are wasting in a traffic jam, Type A's ought to think about the opportunity to think over their day's activities. They also have been told to adopt new, relaxing hobbies that are entirely separate from their careers, and they are learning procedures that will al low them to modify their physiological reactions through such techniques as deep muscle relaxation and learning to slow down physical activity. Still, there is no definitive evidence to date showing that reductions in Type A characteristics result invariably in a decrease in heart disease risk. Moreover, it is unclear just which aspect of Type A behavior is the crucial one, or whether it is a complex of several behaviors, all part of the Type A pat tern ,that is associated with the increased risk. In other words ,we still do not know specifically what it is about Type A behaviors that leads to heart problems, and until we do, programs that attempt to de crease the risk must use relatively expensive and time-consuming procedures, modifying essentially all manifestations of the Type A pattern. Moreover, programs which emphasize the importance of work and achievement. For these reasons, treatment programs that are designed to alter Type A behaviors may be facing an uphill battle. Despite the difficulty in implementing treatment programs to reduce the Type A behavior pattern, such attempts illustrate quite clearly the role that social psychologists can play in the treatment of health problems.
