单选题Obesity is an epidemic to some and an opportunity to others. More than two-thirds of Americans are overweight. Find a way to battle obesity, 1 a huge profit might be made. On February 22nd, 2013 one pharmaceutical firm, Virus, took a small 2 towards this goal. A committee advising America"s Food and Drug Administration (FDA) recommended Vivus"s diet drug, Qnexa. 3 , the pill"s long-awaited final approval may not come until April. The announcement mostly served as a reminder of a struggle which 4 fat into gold. Medical-device and pharmaceutical companies are quite 5 treating the problems that come with obesity. However, they can"t help consumers 6 weight. Allergan, a device-maker, has tried to use its gastric bands to enter the obesity market. The band is fitted near the top of patients" stomach, which helps them feel full 7 during the meal. Allergan has captured about 70% of the worldwide market for gastric bands, but sales are now 8 . The recession has sapped consumers" desire for expensive surgery. Some patients have 9 bands removed because they slipped or proved 10 . In January David Pyott, Allergan"s chief executive, said he would cancel an effort to market the band for teenagers. He is now trying to convince insurers of the gastric band"s 11 . Drug companies have had even more 12 than device-makers. It has been 13 years since the FDA approved a 13 diet pill. That drug, Roche"s Xenical, has 14 side-effects. The FDA rejected Vivus"s Qnexa in 2010 over 15 for the safety of pregnant women and the quickening of patients" heart rates. However, Vivus"s new data in 2013 apparently satisfied the FDA"s advisory committee. But the agency may yet 16 the drug. 17 Qnexa is approved, it is unclear that patients will buy it. Qnexa 18 two medicines that are already on the market. Both medicines are generic, which means that doctors may 19 the existing drugs rather than Qnexa"s more expensive version. For now, it is more 20 to treat fat patients than to try to make them slim.

单选题Convincing the public to follow health advice can be tough and time-consuming. This may be why changes to health messages are often fiercely resisted by those whose job is to get the advice across. So, for example, the suggestion that smokers who cannot quit should reduce their exposure to harm by switching to chewing tobacco met with extreme opposition. A still more ferocious debate is emerging over the health impact of sunshine. For the past 20 years, advice on sunlight has come from dermatologists who rightly warn people to cover up when they venture outside for fear of developing skin cancer. But evidence from researchers in other fields now suggests that short periods in the sun without protection—sometimes as little as a few minutes a day—can prevent most other major forms of cancer. This surprising conclusion stems from findings that vitamin D, which is made by skin cells exposed to the sun" s ultraviolet rays, is a potent anti-cancer agent. The researchers who made this discovery are eager to be heard. But their message is about as welcome as a bad rash, particularly in countries such as Australia and the US where fair-skinned immigrants living at Mediterranean latitudes have made skin cancer a huge problem. The American Academy of Dermatology argues that advocating one carcinogen—UV radiation—to protect against other forms of cancer is dangerous and misleading. If people need more vitamin D, they should take a multivitamin or drink milk fortified with it, says the academy. Unfortunately , the solution is not as simple as that. Critics also argue that the protective effect of sunlight is not yet proved. While this may be true, the evidence is very suggestive. The case is built on several studies that bring together cellular biology, biochemistry and epidemiology. And all the criticism of this theory counts for nothing if, as some of its advocates, suggest, the number of people dying for lack of sunlight is four times as high as those dying from skin cancer. At the same time, those advocates must not overstate their case. Everyone wants to save as many lives as they can. What we need now is for national medical research bodies and cancer research organizations to investigate the relative risks and benefits of sunshine. This will almost certainly mean more epidemiological work, which should start as soon as possible. As for the public: give them the facts, including risk estimates for short periods in the sun—and for covering up, It is patronizing(施恩于人的)to assume that people cannot deal with complex messages. What we definitely do not want is a war of words between groups with polarized views, and no prospect of the issue being resolved. That way will only lead to confusion, distrust of doctors and more unnecessary deaths.

单选题It was possible to define male and female roles easily by the division of labour. Men worked outside the home and earned the income to raise their families. While women cooked the meals, there was not much opportunity for men or women to exchange their roles. But by the middle of this century, men's and women's roles were becoming less firmly fixed. In the 1950s, economic and social success was the aim of the typical American. But in the 1960s a new force called the counterculture (反主流文化) developed. The people involved in this movement did not value the middle-class American goals. The counterculture presented men and women with new role choices. Taking more interest in child care, men began to share child-raising tasks with their wives. Actually some young men and women moved to communal homes or farms where the economic and child care responsibilities were shared equally by both sexes. In addition, many Americans did not value the traditional male role of soldier. Some young men refused to be drafted as soldiers to fight in the war in Vietnam. In terms of numbers, the counterculture was not a very large groups of people. But its influence spread to many parts of American society. Working men of all classes began to change their economic and social patterns. Industrial workers and business executives alike cut down on "overtime" work so that they could spend more leisure time with their families. Some doctors, lawyers, and teachers turned away from high paying situations to practice their professions in poorer neighborhoods. In the 1970s, the feminist movement, or women's liberation, produced additional economic and social changes. Women of all ages and at all levels of society were entering the work force in greater numbers. Most of them still took traditional women's jobs such as public school teaching, nursing, and secretarial work. But some women began to enter traditionally male occupations: police work, banking dentistry, and construction work. Women were asking for equal work, and equal opportunities for promotion. Today the experts generally agree that important changes are taking place in the roles of men and women. Naturally, there are difficulties in adjusting to these changes.

单选题If sustainable competitive advantage depends on work-force skills, American firms have a problem. Human resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered as an individual responsibility. Labor is simply another factor of production to be hired or rented at the lowest possible cost much as one buys raw materials or equipment. The lack of importance attached to human resource management can be seen in the corporation hierarchy. In an American firm the chief financial officer is almost always second in command. The post of head of human resource managements is usually a specialized job, often at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer(CEO). By way of contrast, in Japan the head of human resource management is central — usually the second most important executive, after the CEO, in the firm's hierarchy. While American firms often talk about the vast amounts spent on training their work-forces, in fact they invest less in the skill of their employees than do the Japanese or German firms. The money they do invest is also more highly concentrated on professional and managerial employees. And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies. As a result, problems emerge when new breakthrough technologies arrive. If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers in Germany(as they do), the effective cost of those stations is lower in Germany than it is in the United Stated. More time is required before equipment is up and running at capacity, and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be employed. The result is a slower pace of technological change. And in the end the skills of the bottom half of the population affect the wages of the top half. If the bottom half can't effectively staff the processes that have to be operated, the management and professional jobs that go with these processes will disappear.

单选题The trouble with television is that it discourages concentration. Television's variety becomes a narcotic, not a stimulus. Its serial, kaleidoscopic exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction-except on the television, typically, the spans allotted are on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps one of the most precious gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention-and holding it-is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite simply, television operates on the appeal to the short attention span. In the case of news, this practice, in my view, results in inefficient communication. I question how much of television's nightly news effort is really absorbable and understandable. Much of it is what has been aptly described as "machine-gunning with scraps. " I think the technique fights coherence. I think it tends to make things ultimately boring and dismissible (unless they are accompanied by horrifying pictures) because almost anything is boring and dismissible if you know almost nothing about it. I believe that TV's appeal to the short attention span is not only inefficient communication but decivilizing as well. Consider the casual assumptions that television tends to cultivate: that complexity must be avoided, that visual stimulation is a substitute for thought, that verbal precision is an anachronism. It may be old-fashioned, but I was taught that thought is words, arranged in grammatically precise ways. There is a crisis of literacy in this country. One study estimates that some 30 million adult Americans are "functionally illiterate" and cannot read or write well enough to answer the want ad or understand the instructions on a medicine bottle. And while I would not be so simplistic as to suggest that television is the cause, I believe it contributes and is an influence.
