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The great recession may be over, but this era of high joblessness is probably beginning. Before it ends, it will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics, our culture, and the character of our society for years. No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways: they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending. But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U. S. , lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes. Income inequality usually falls during a recession, but it has not shrunk in this one. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them-- especially for young people. The research of Till Von Wachter, the economist at Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind. In the Internet age, it is particularly easy to see the resentment that has always been hidden within American society. More difficult, in the moment, is discerning precisely how these lean times are affecting society' s character. In many respects, the U. S. was more socially tolerant entering this recession than at any time in its history, and a variety of national polls on social conflict since then have shown mixed results. We will have to wait and see exactly how these hard times will reshape our social fabric. But they certainly will reshape it, and all the more so the longer they extend.

单选题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I"m usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today"s children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago. Why are America"s kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in community, among other things—and a growing perception that the world is a more dangerous place. Given that we can"t turn the clock back, adults can still do plenty to help the next generation cope. At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress. To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep. Limit the amount of virtual (虚拟的) violence your children are exposed to. It"s not just video games and movies; children see a lot of murder and crime on the local news. Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale. Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn"t have to ruin your life. (314 words)

单选题Most Americans today have some insurance against long-term illness or injury, or the death of the family wage-earner. Nearly all who work, including the self-employed, are covered by retirement programs. Four out of five employees now have access to unemployment benefits. The Social Security law, which covers more than 90 percent of the work force, provides a national system of payments in old age and disability benefits. Over the years the law has been broadened' to give greater protection in all categories. The Social Security system is financed through a tax paid by workers and their employers during the years of employment. Self-employed persons, who also pay into the system, are covered as well. When workers retire at age 65, they receive monthly payments on a scale to their previous earnings; reduced benefits am paid to those retiring at ages 62 through 64. Benefits are also paid to nonworking widows and widowers, to children under 18 and to dependent parents. More than 35 million people currently receive these monthly payments. Unemployment insurance is financed through a payroll(工资单) tax paid by the employer. The federal government provides money to the states to cover the cost of operating this program; the states determine the conditions under which benefits are paid. Civilians who work for the federal government share the cost of their pension system and group health insurance programs. Most state and city government workers have similar protections. The federal government also has programs to protect railroad workers and members of the armed forces. In addition, all the states have "workers' compensation" laws that provide payments to workers or their families for jobconnected injury or death. The federal government makes grants to the states to help them finance public assistance and social services program for the needy and those who have exhausted their unemployment benefits. The federal government also helps the states meet the medical costs of the needy aged, the blind and disabled, and dependent children. Millions of workers in industry get extra protection through private plans offered by their employers on a fully paid or share-the-cost basis. These usually provide sickness and accidents benefits, hoptalization and medical care costs, disability and retirement payments. More than 800 000 business organizations offer some such plan.

单选题There are many aspects of the women's liberation movement. Some women agree with all of the goals of women's liberation. They want full equality with men in every aspect of life. In marriage, they want husbands and wives to share all of the work and responsibilities of a home and family. In work, they want women and men to have the same jobs and the same chance to succeed. They want women to be paid just as much as men are for the same work. Other women agree with some of the ideas of women's liberation. They want the same pay if they hold the same job as a man. At home, however, they do not expect their husbands to share in the cleaning, cooking, and other household jobs. It is important to remember that the women's liberation movement is not concerned only with concrete issues. The movement is also concerned with attitudes and beliefs. One example of this concern is the issue of a woman's identity. A woman's identity is what she thinks of herself as a person, who she thinks she is, and what she thinks she can do. Some women do not think they are capable of doing anything important, The women's liberation movement would like to help these women improve their view of themselves. Mary women who are concerned with women's liberation have taken jobs, have helped others, have raised healthy children, and have done many other things to contribute to their communities. They have shown that they are capable of being good leaders and of doing many important things.
