Obesity is defined as body weight of 15 percent or more above the ideal for one’s height and age. 62 this criterion, about one third of the adult population of the United States is obese. The 63 of obesity vary in different races, cultures, sub-cultures, and social classes. In industrialized countries, fatness tends to be 64 correlated with socioeconomic status: people in lower social classes tend to be more obese. In economically backward nations, the direction of the correlation is reversed; the richer, the fatter. The situation in the underdeveloped world probably approximates the 65 of affairs through most of human evolution. Particularly for women, 66 pregnancies could 67 into times of scarcity, larger internal food 68 were adapted in the face of variable external reserves. Although obesity may sound like a (n) 69 phenomenon, it is to some degree 70 relative. A study of black and white undergraduates yielded 71 results. Even though blacks, and especially black females, were heavier than whites, they were more satisfied with their weight and less likely to find weight in other people 72 Men were more concerned 73 the weight of their dates than women were, but black men were 74 likely to refuse to date a woman because of her weight. Contemporary North American culture is 75 with thinness, particularly for women. Compared to the Rubenesque view of beauty of just a few centuries ago, the prototypes of feminine beauty 76 in the mass media today look emaciated, that is, extremely thin. The standards have even changed 77 since the 1950s, when the prototype was replete with large breasts and slightly protruding abdomen. A study of Playboy centerfolds found a ten percent decrease in the ratio of weight to height from the late 1950s to the late 1970s, 78 by a dramatic increase in the number of articles on dieting in popular women’s magazines. In 79 to contemporary Western societies, some other cultures 80 beauty with bulk. This most often occurs in societies in which food is scarce, 81 women who are healthy and have more resources tend to be heavier and hence are seen as more attractive.

Very old people do raise moral problems for almost everyone who comes into contact with them. Their values—this can’t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are not necessarily the most important things for the very old people. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone on bed, taking no notice of the worms. Is it interfering with personal freedom to insist that they go to live with .some of their relatives so that they might be taken better care of Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old.Indeed, the old can be easily hurt or harmed. The body is like a car: it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. Never forget that such operations are painful experience, however good the results. At what point should you cease to treat the old body Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate (使......活动) the old body, knowing that it is designed to die You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try on the principle that while there’s life, there’s hope.When you talk to old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have fun. It is implied in Para. I that（）
·Read the following article about knowledge acquisition and the questions on the opposite page.·For each question 15-20, mark one letter (A,B, C or D ) on your Answer Sheet for the answer you choose.In business, if not politics, the world has quietened down a bit: the number of spectacular bankruptcies, indictments, scandals, and implosions is not as high as it was in 2001 and 2002. Although executives still have to face a global slowdown, the uncertain effects of the war in Iraq, and the still fresh confusion over SARS, they might now be excused a deep breath and a look at aspects of their businesses that may have been neglected in the scramble to stay on top of new accounting laws and restated earnings.One area to start catching up on is knowledge. This is tree both personally, as executives work out whether or not they are staying on top of internal or external developments, but also at the level of companies. A survey of knowledge management, "Knowledge Unplugged", published in 2001 by McKinsey, found that the best-performing companies were far more likely than the worst-performing ones to use creative techniques for acquiring, processing and distributing knowledge — everything from emphasizing teamwork in product development to holding "idea contests" and laying to avoid boring daily routines.But creating an atmosphere in which knowledge can be shared can be almost as challenging as obtaining it in the first place. This is the potential prisoner’s dilemma of knowledge: the more valued it becomes, the less incentive employees have to share it with one another, at the risk of losing the competitive advantage of what they know — or, worse, seeing another profit at their expense. This proves to be even more true at the company level. While firms might mm to external partners m enhance their knowledge base, the sharing will be incomplete without mutual trust.Since "knowledge" is such a vague term, it helps to have specific goals in mind when looking to gain more of it. Are you looking for information about your company, or industry in particular Despite the general slowdown in executive education, there are still a number of courses devoted specifically to helping managers in given industries — technology, for example, or health care. Are you more concerned with acquiring more knowledge, or putting it to better use Do you need to move quickly, or is this a subject that needs to be explored in greater depthAnd bear in mind that styles of learning vary. Some people will profit most from informal networking; some enjoy learning in a classroom; others will be able to take advantage of the company intranet. Be flexible in the pursuit of knowledge; it is better to set performance targets, concentrate on meeting them, and allow individuals and their teams to explore their own solutions. Sometimes the best way to generate knowledge is simply a bit of brainstorming.The edition of Executive Education Outlook looks at the options available to executives in gaining knowledge, and enhancing what they already have. It includes a look at the state of distance learning- neither the revolution the hype claimed it would be in the late 1990s, nor completely dismissable — as a possible conduit of knowledge, the best place to go for new programmes in knowledge management, and a consideration of the demand for the best sources of knowledge: business-school academics. Concentrating on knowledge now may be the best way to be prepared for the next challenges facing the business world. What reason is given by McKinsey for the success of best-performing companies
