单选题The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities, and literally thousands of health spas developed around the country to capitalize (获利) on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in most major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well. Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000: National Health Promotion and Disease Prevention Objectives.

单选题{{B}}Passage Three{{/B}} It is curious how often sympathy for the old and infirm takes a form which actually humiliates them.' Their friends, with good will, sometimes lean forward to rearrange their neckwear, touching their hair or patting their faces--things they would never presume to do, unasked, to one of their contemporaries. An equally humiliating habit is to talk about old people in front of them as if they were not there, discussing their health. It is now universally accepted that children should be encouraged to do as much as they can for themselves in order to develop their brains and muscles, but so few people today seem to have time to allow the elderly the same means of keeping their minds and muscles active. They perform innumerable services for the old that they would be much better left to do, even with a struggle, for themselves. Convenient flats, "motherly" visitors, or organized entertainments cannot make up for the fundamental need which must be satisfied the need to retain to the end of life human dignity and the respect of one's fellows.

单选题{{B}}21-25{{/B}} This country, as Lincoln said, belongs to the people. So do the natural resources which make it rich. They supply the basis of our prosperity now and hereafter. In preserving them, which is a national duty, we must not forget that monopoly is based on the control of natural resources and natural advantages, and that it will help the people little to conserve our natural wealth unless the benefits which it can yield are given back to the people. Let us remember, also, that conservation does not stop with the natural resources. The principle of making the best use of all we have requires that we stop the waste of human life in industry and prevent the waste of human welfare which flows from the unfair use of concentrated power and wealth in the hands of men whose eagerness for profit blinds them to the cost of what they do. We have no higher duty than to promote the efficiency of the individual. There is no surer road to the efficiency of the nation.

单选题{{B}}11-15{{/B}} The next decade could see commuters speeding to work at about 300 miles per hour aboard magnetic levitation vehicles, according to a report by Argonne National Laboratories. But before "maglev" vehicles can become commercial successes, the report says, people need to stop thinking of them as high-speed trains. Instead, consider them low-flying aircraft. Argonne contends that maglev vehicles will be best suited to replace commuter aircraft. Plane flights under 600 miles are the least energy-efficient, and maglev "planes" should cut these fuel needs by up to 75 percent. Reportedly, the money saved by a 2,000-mile maglev network linking major cities world more than pay for its construction in 20 years. The quiet purr of levitating crafts would also be a balm for neighborhoods tormented by the roar of conventional takeoffs and landings. The technology behind magnetic levitation is already well understood, the report notes. The west Germans and the Japanese already well understood, the report notes. The West Germans and the Japanese have several full-scale working models. Meanwhile, research in the United States has lapsed.

单选题{{B}}Passage Two{{/B}} In some countries where racial prejudice is acute, violence has so come to be taken for granted as a means of solving differences, that it is not even questioned. There are countries where the white man imposes his rule by brute force; there are countries where the black man protests by setting fire to cities and by looting and pillaging. Important people on both sides, who would in other respects appear to be reasonable men, get up and calmly argue in favor of violence--as if it were a legitimate solution, like any other. What is really frightening, what really fills you with despair, is the realization that when it comes to the crunch, we have made no actual progress at all. We may wear collars and ties instead of war-paint, but our instinct remain basically unchanged. The whole of the recorded history of the human race, that tedious documentation of violence, has taught us absolutely nothing. We have still not learnt that violence never solves a problem but makes it more acute. The sheer horror, the bloodshed, the suffering means nothing. No solution ever comes to light the morning after when we dismally contemplate the smoking ruins and wonder what hit us. The truly reasonable men who know where the solutions lie are finding it harder and harder to get a hearing. They are despised, mistrusted and even persecuted by their own kind because they advocate such apparently outrageous things as law enforcement. If half the energy that goes into violent acts were put to good use, if our efforts were directed at cleaning up the slums and ghettos, at improving living-standards and providing education and employment for all, we would have gone a long way to arriving at a solution. Our strength is sapped by having to mop up the mess that violence leaves in its wake. In a well-directed effort, it would not be impossible to fulfill the ideals of a stable social program. The benefits that can be derived from constructive solutions are everywhere apparent in the world around us. Genuine and lasting solutions are always possible, providing we work within the framework of the law. Before we can even begin to contemplate peaceful co-existence between the races, we must appreciate each other's problems. And to do this, we must learn about them: it is a simple exercise in communication, in exchanging information. "Talk, talk, talk," the advocates of violence say, "all you ever do is talk, and we are none the wiser." It's rather like the story of the famous barrister who painstakingly explained his case to the judge. After listening to a lengthy argument the judge complained that after all this talk, he was none the wiser. "Possibly, my Lord," the barrister replied, "none the wiser, but surely far better informed." Knowledge is the necessary prerequisite to wisdom: the knowledge that violence creates the evils it pretends to solve.

单选题 Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a dayin the not-too-distant future when all autos will be abandoned and allowed to rust. Otherauthorities, however, think the auto is here to stay. They hold that the car will remain a leadingmeans of travel in the foreseeable future. The motorcar will undoubtedly change significantly over the next 30 years. It should becomesmaller, safer, and more economical, and should not be powered by the gasoline engine. The carof the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in urbantraffic congestion (拥挤). One proposed solution to this problem is the automated highwaysystem. When the auto enters the highway system, a retractable (可伸缩的) arm will drop from theauto and make contact with a rail, which is similar to those powering subway trains electrically.Once attached to the rail, the car will become electrically powered from the system, and controlof the vehicle will pass to a central computer. The computer will then monitor all of the car'smovements. The driver will use a telephone to dial instructions about his destination into the system. Thecomputer will calculate the best route, and reserve space for the car all the way to the eorrect exitfrom the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that willwarn of his coming exit. It is estimated that an automated highway will be able to handle 10000vehicles per hour, compared with the 1400 to 2000 vehicles that can be carried by a present-dayhighway.
