单选题Dear Dr. Benjamin, Congratulations on your nomination as United States Surgeon General. Based on your extraordinary career and your commitment to 51 health disparities among underserved populations, no doubt your tenure will be marked by great progress toward the goal of improved health for all Americans. Each United States Surgeon General has the unique opportunity to create his or her own lasting legacy. Dr. Koop focused on smoking prevention. Dr. Satcher one of 52 mentors, released the first comprehensive report on mental health. We encourage you to build your own legacy 53 concept of prevention through healthy lifestyles -- a legacy that is both sustainable and cost-effective. This also is an important issue for Members of Congress, many of whom believe that 54 prevention and wellness initiatives will bring down costs and help people lead healthier lives. The American College of Sports Medicine (ACSM) would be honored to partner with you on such an initiative. ACSM, the largest sports medicine and exercise science organization in the world, 55 ready to work with you to increase healthy behaviors-especially physical activity--throughout the life span. During this crucial period of health system reform, we've been advocating for strategies that support preventive medicine not just through diagnostic testing, 56 promoting healthy, active behaviors that all Americans can achieve at little or no cost. In fact, ACSM already has a working agreement with the Surgeon General's office, focused on a series of healthy-lifestyle public service announcements for our Exercise Is MedicineTM program, a program that 57 calls on doctors to encourage their patients to incorporate physical activity and exercise into their daily routine. As you are 58 aware, physical activity can prevent and treat a host of chronic conditions -- such as heart disease, type II diabetes, and obesity –that currently plague our country. Your example as 59 whose family has suffered from preventable disease and who demonstrates healthy lifestyles can be powerful indeed. Anytime either before or after your appointment is confirmed, we would 60 the opportunity to meet with you and your staff to discuss how we, along with other leading health organizations, can enhance the prevention paradigm through physical activity. Again, Dr, Benjamin, I extend our deepest congratulations and best wishes. Sincerely, James Pivarnik, Ph.D., FACSM President, American College of Sports Medicine

单选题 Whenever two or more unusual traits or situations are found in the same place, it is tempting to look for more than a coincidental relationship between them. The high Himalayas and the Tibetan plateau certainly have extraordinary physical characteristics, and the cultures which are found there are also unusual, though not unique. However, there is no intention of adopting Montesquieu's view of climate and soil as cultural determinants. The ecology of a region merely poses some of the problems faced by the inhabitants of the region, and while the problems facing a culture are important to its development, they do not determine it. The appearance of the Himalayas during the late Tertiary Period and the accompanying further raising of the previously established rages had a marked effect on the climate of the region. Primarily, of course, it blocked the Indian monsoon (季风) from reaching Central Asia at all. Secondarily, air and moisture from other directions were also reduced. Prior to the raising of the Himalayas, the land now forming the Tibetan uplands had a dry continental climate with vegetation and animal life similar to that of the rest of the region on the same parallel, but somewhat different than that of the areas farther north, which were already drier. With the coming of the Himalayas and the relatively sudden drying out of the region, there was a severe thinning out of the animal and plant population. The ensuing incomplete Pleistocene glaciations (冰蚀) had a further thinning effect, but significantly did not wipe out life in the area. Thus after the end of the glaciations there were only a few varieties of life extant from the original continental species. Isolated by the Kunlun range from the Tarim basin and Turfan depression, species which had already adapted to the dry steppe climate, and would otherwise have been expected to flourish in Tibet, the remaining native fauna and flora (动植物群) multiplied. Armand describes the Tibetan fauna as not having great variety, but being "striking" in the abundance of the particular species that are present. The plant life is similarly limited in variety, with some observers finding no more than seventy varieties of plants in even the relatively fertile Eastern Tibetan valleys, with fewer than ten food crops. Tibetan "tea" is a major staple, perhaps replacing the unavailable vegetables. The difficulties of living in an environment at once dry and cold, and populated with species more usually found in more hospitable climates, are great. These difficulties may well have influenced the unusual polyandrous (一妻多夫的) societies typical of the region. Lattimore sees the maintenance of multiple-husband households as being preserved from earlier forms by the harsh conditions of the Tibetan uplands, which permitted no experimentation and "froze" the cultures which came there. Kawakita, on the other hand, sees the polyandry as a way of easily permitting the best householder to become the head husband regardless of. age. His detailed studies of the Bhotea village of Tsumje do seem to support this idea of polyandry as a method of talent mobility is a situation where even the best talent is barely enough for survival. In sum, though arguments can be made that a pre-existing polyandrous system was strengthened and preserved (insofar as it has been) by the rigors of the land, it would certainly be an overstatement to lay causative factors of any stronger nature to the ecological influences in this case.

单选题I have long believed that trouble between the races is seldom what it appears to be. It was not hard to see after my first talks with students that racial tension on campus is a problem that misrepresents itself. It has the same look, the typical pattern, of Americas timeless racial conflict.. .white racism and black protest. And I think part of our concern over it comes from the fact that it has the feel of a relapse, illness gone and come again. But if we are seeing the same symptoms, I don't believe we are dealing with the same illness. For one thing, I think racial tension on campus is the result more of racial equality than inequality. How to live with racial difference has been America's profound social problem. For the first 100 years or so following emancipation it was controlled by a legally approved inequality that acted as a buffer between the races. No longer is this the case. On campuses today, as throughout society, blacks enjoy equality under the law — a profound social advancement. No student may be kept out of a class or a dormitory or an extracurricular activity because of his or her race. But there is a paradox here: On a campus where members of all races are gathered, mixed together in the classroom as well as socially, differences are more exposed than ever. And this is where the trouble starts. For members of each race — young adults coming into their own , often away from home for the first time — bring to this site of freedom, exploration, and now, today, equality, very deep fears and anxieties, not fully developed feelings of racial shame, anger, and guilt. These feelings could lie hidden in the home, in familiar neighborhoods, in simpler days of childhood. But the college campus, with its structures of interaction and adult-level competition — the big exam, the dorm, the "mixer" — is another matter. I think campus racism is born of the rub between racial difference and a setting, the campus itself, devoted to interaction and equality. On our campuses, such concentrated micro-societies, all that remains unresolved between blacks and whites, all the old wounds and shames that have never been addressed, present themselves for attention-and present our youth with pressures they cannot always handle.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill--the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.

单选题To what extent are the unemployed failing in their duty to society to work, and how far has the State an obligation to ensure that they have work to do? It is by now increasingly recognized that workers may be thrown out of work by industrial forces beyond their control, and that the unemployed are in some sense paying the price of the economic progress of the community. But concern with unemployment and the unemployed changes sharply. The issues of duty and responsibility were re-opened and made active by the unemployment scare of 1971--1972. Rising unemployment and increased sums paid out in benefits to the workless had reawakened controversies which had been inactive during most of the period of fuller employment since the war ended the Depression. It looked as though in future there would again be too little work to go round, so there were arguments about how to produce more work, how the available work should be shared out, and who was responsible for unemployment and the unemployed. In 1972 there were critics who said that the State's action in allowing unemployment to rise was a barrier of faith, a breaking of the social contract between society and the worker. Yet the main contribution by employers to unemployment--such as laying off workers in order to introduce technological changes and maximize profit-tended to be ignored. And it was the unemployed who were accused of failing to honor the social contract, by not fulfilling their duty to society to work. In spite of general concern at the scale of the unemployment statistics when the unemployed were considered as individuals they tended to attract scorn and threats of punishment. Their capacities and motivation as workers and their values as members of society became suspect. Of all the myths of the Welfare State, stories of the workshy and stealing have been the least well founded on evidence, yet they have proved the most persistent. The unemployed were accused of being responsible for their own workless condition, and doubts were expressed about the State's obligation either to provide them with the security of work or to support them through social security. Underlying the arguments about unemployment and the unemployed is a basic disagreement about the nature and meaning of work in society. To what extent can or should work be regarded as a service, not only performed by the worker for society but also made secure for the worker by the State, and subsidized if necessary? And apart from cash are there social pressures and satisfactions which cause individuals to seek and keep work, so that the workless need work rather than just cash?
