Although science has made enormous steps in making food more fit to eat, it has at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to the diet as well, especially cancer of the colon (结肠). Different cultures are more likely to develop certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates (硝酸盐)commonly used to preserve color in meats, and other food additives, accused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin(青霉素) to beef and poultry(家禽),and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drags are administered to animals not for medicinal purposes, hut for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.

Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put aside because of the change of fashion. When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear. Changing fashions are nothing more than the intentional creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. Skirts are lengthened or shortened, neck-lines are lowered or raised, and so on. No one can claim that the fashion industry contributes anything really important to society. Fashion designers are rarely concerned with vital things like warmth, comport and durability. They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right. There can hardly be a man who hasn't at some time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or delicately picking her way through deep snow in high-heeled shoes. When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious. Do the constantly changing fashions of women's clothes, one wonders, reflect basic qualities of inconstancy and instability? Men are too clever to let themselves be cheated by fashion designers. Do their unchanging styles of dress reflect basic qualities of stability and reliability? That is for you to decide.

单选题The Workers' Role in Management Traditionally, it has been the workers' role to work and management's role to manage. Managers have planned and directed the firm's operations with little thought to consulting the labor force. Managers have rarely felt compelled to obtain the workers' opinions or to explain their decisions to their employees. At most, companies have provided" suggestion boxes" in which workers could place ideas for improving procedures. In recent years, however, many management specialists have been arguing that workers are more than sellers of labor--they have a vital stake in the company and may be able to make significant contributions to its management. Furthermore, major company decisions profoundly affect workers and their dependents. This is particularly true of plant closings, which may put thousands on the unemployment lines. Should workers, then, play a stronger role in management? Workers should have a role in management. At the very least, the labor force should be informed of major policy decisions. (A common complaint among rank-and-file workers is the lack of information about company policies and actions.) Between 1980 and 1985 about five million workers were the victims of plant closings and permanent layoffs, often with no warning. At least 90 days' notice ought to be given in such instances so that workers have time to adjust. Management should consult workers before closing a plant, because the workers might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions that will help keep the plant operating. It should become a general practice to include workers in some managerial decision making. There ought to be representatives of the workers on the firm's board of directors or other major policymaking groups. If rank-and-file workers are given a voice in the planning and management of the work flow, they will help to make improvements, their morale will rise, and their productivity will increase. As a further incentive, they must be given a share in the company's profits. This can be done through employee stockownership plans, bonuses, or rewards for efficiency and productivity. Finally, when a plant can no longer operate at a profit, the workers should be given the opportunity to purchase the plant and run it themselves.

单选题 阅读下面的短文，文中有15处空白，每处空白给出4个选项。请根据短文的内容，从4个选项中选择1个最佳答案。 {{B}}Canal{{/B}} Today, most countries in the world have canals. Even in the twentieth century, goods can be moved more cheaply by boat {{U}}(51) {{/U}} by any other means of trans- port. Some canals, such as the Suez or the Panama, {{U}}(52) {{/U}} ships weeks of time by making their voyage a thousand miles shorter. Other canals permit boats to reach cities that are not located on the coast. Still other canals {{U}}(53) {{/U}} lands where there is too much water, help or irrigate fields where there is not enough water, and furnish water power for factories and mills. The {{U}}(54) {{/U}} of a canal depends on the kind of boats going through it. The canal must be wide enough to permit two of the {{U}}(55) {{/U}} boats using it to {{U}}(56) {{/U}} each other easily. It must be deep enough to leave about two feet of water {{U}}(57) {{/U}} the keel of the largest boat using the canal. Some canals have sloping sides, {{U}}(58) {{/U}} others have sides that are nearly vertical. Canals that are cut through rock can have nearly vertical sides. However, canals with earth banks may crumble if the angle of their sides is too steep. Some canals are lined with brick, stone, or concrete to keep the water {{U}}(59) {{/U}} soaking into the mud. This also permits ships to go {{U}}(60) {{/U}} greater speeds, since they cannot make the banks fall in by stirring up the water. In small canals with mud banks, ships and barges must {{U}}(61) {{/U}} their speed. When the canal goes {{U}}(62) {{/U}} different levels of water, the ships must be raised or lowered from one level to the other, This is generally done by means of locks. If a ship wants to go up to higher water, the lower end of the lock opens to let the boat in. Then this gate closes, and the water is let into the lock chamber from the upper level. This raised the level of the water in the lock {{U}}(63) {{/U}} it is the same as the upper level of water. Now the upper gates can be opened to {{U}}(64) {{/U}} the ship into the higher water. Of course there must always be enough water on the upper level to allow for the flooding of the lock. Sometimes a canal contains a {{U}}(65) {{/U}} of locks when the difference in levels is very great.

单选题Fitness Movement The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise. Millions of individuals became engaged in a variety of aerobic activities, and 1 thousands of health spas developed around the country to capitalize on his 2 interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed 3 to this aerobic fitness movement, even a national chain with spas in most major cities. However, their 4 was not on aerobics, but rather on weight-training programs designed to develop muscular mass, 5 , and endurance in their primarily male 6 . These fitness spas did not seem to benefit 7 from the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs 8 few, if any, health benefits. In recent years, however, weight training has again become increasingly 9 for males and for females. Many 10 programs focus not only on developing muscular strength and endurance but on aerobic fitness as well. 11 , most physical fitness tests have usually included measures of muscular strength and endurance, not for health related reasons, but primarily 12 such fitness components have been related to performance in athletics. 13 , in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health 14 as well. The American College of Sports Medicine now 15 that weight training be part of a total fitness program for healthy Americans.

单选题 {{B}}Extending the workplace by means of computer{{/B}} Telecommuting—substituting the computer for the trip to the job—as been hailed as a solution to all kinds of problems related to office work. For worker it promises freedoms from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high per formers on board, minimizes tardiness and absenteeism by eliminating commutes, allows periods of solitude for high-concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush—our congestion and improve air quality. But these benefits do not come easily. Making a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images. Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer form New York cities moves to the tranquil Adirondack Mountains and stays in contact with her office via computer. A manager comes into his office three days a week and works at home the other two. An accountant stays home to care for her sick child; she hooks up her telephone modem connections and does office work between calls to the doctor. These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done. Management, too, must separate the myth from the reality. Although the media has paid a great deal of attention to telecommuting, in most cases it is employee's situation, not the availability of technology, that precipitates a telecommuting arrangement. That is partly why, despite the widespread press coverage, the number of companies with work-at-home programs or policy guidelines remains small.
