单选题Industrial production managers coordinate the resources and activities required to produce millions of goods every year in the United States. Although their duties vary from plant to plant, industrial production managers share many of the same major responsibilities. These responsibilities include production scheduling, staffing, procurement and maintenance of equipment, quality control, inventory control, and the coordination of production activities with those of other departments. The primary mission of industrial production managers is planning the production schedule within budgetary limitations and time constraints. They do this by analyzing the plant's personnel and capital resources to select the best way of meeting the production quota. Industrial production managers determine, often using mathematical formulas, which machines, will be used, whether new machines need to be purchased, whether overtime or extra shifts are necessary, and what the sequence of production will be. They monitor the production run to make sure that it stays on schedule and correct any problems that may arise. Industrial production' managers also must monitor product standards. When quality drops below the established standard, they must determine why standards are not being maintained and how to improve the product. If the problem relates to the quality of work performed in the plant, the manager may implement better training programs, reorganize the manufacturing process, or institute employee suggestion or involvement programs. If the cause is substandard materials, the manager works with the purchasing department to improve the quality of the product's components. Because the work of many departments is interrelated, managers work closely with heads of other departments such as sales, procurement, and logistics to plan and implement company goals, policies, and procedures. For example, the production manager works with the procurement department to ensure that plant inventories are maintained at their optimal level. This is vital to a firm's operation because maintaining the inventory of materials necessary for production ties up the firm's financial resources, yet insufficient quantities cause delays in production. A breakdown in communications between the production manager and the purchasing department can cause slowdowns and a failure to meet production schedules. Just-in- time production techniques have reduced inventory levels, making constant communication among the manager, suppliers, and purchasing departments even more important. Computers play an integral part in this coordination. They also are used to provide up-to-date information on inventory, the status of work in progress, and quality standards. Production managers usually report to the plant manager or the vice president for manufacturing, and may act as liaison between executives and first-line supervisors. In many plants, one production manager is responsible for all aspects of production. In large plants with several operations, there are managers in charge of each operation, such as machining, assembly or finishing.

单选题No country in the world has more daily newspapers than the USA. There are almost 2,000 of them, as compared with 180 in Japan, 164 in Argentina and 111 in Britain. The quality of some American papers is extremely high and their views are quoted all over the world. Distinguished dailies like The Washington Post or The New York Times have a powerful influence all over the country. However, the Post and the Times are not national newspapers in the sense that The Times is in Britain or Le Monde is in France, since each American city has its own daily newspaper. The best of these present detailed accounts of national and international news, but many tend to limit themselves to state or city news. Like the press in most other countries, American newspapers range from the " sensational", which feature crime, sex and rumor, to the serious, which focus on factual news and the analysis of world events. But with few exceptions American newspapers try to entertain as well as give information, for they have to compete with television. Just as American newspapers give way to all tastes, so do they also try and apply to readers for all political persuasions. A few newspapers support extremist groups on the far right and on the far left, but most daily newspapers attempt to attract middle-of-the-road Americans who are essentially moderate. Many of these pipers print columns by well known journalists of different political and social views, in order to present a balanced picture. As in other democratic countries American newspapers can be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once bravely uncovered political scandals(丑闻)or crimes, for instance, the Watergate Affair. The newspapers drew the attention of the public to the fears of the Vietnam War.

单选题Design of all the new tools and implements is based on careful experiments with electronic instruments. First, a human "guinea pig" is tested using a regular tool. Measurements are taken of the amount Of work done, and the buildup of heat in the body. Twisted joints and stretched muscles can not perform as well, it has been found, as joints and muscles in their normal positions. The same person is then tested again, using a tool designed according to the suggestions made by Dr. Tichauer. All these tests have shown the great improvement of the new designs over the old. One of the electronic instruments used by Dr. Tichauer, the myograph (肌动记器), makes visible through electrical signals the work done by human muscle. Another machine measures any dangerous features of tools, thus proving information upon which to base a new design. One conclusion of tests made with this machine is that a tripod (三脚架) stepladder is more stable and safer to use than one with four legs. This work has attracted the attention of efficiency experts and time-and-motion-study engineer, but its value goes far beyond that. Dr. Tichauer's first thought is for the health of the tool user. With the repeated use of the same tool all day long on production lines and in other jobs, even light manual work can put a heavy stress on one small area of the body. In time, such stress can cause a disabling disease. Furthermore, muscle fatigue is a serious safety hazard. Efficiency is the by-product of comfort, Dr. Tichauer believes, and his new designs for traditional tools have proved his point.

单选题I had never been in the public ward of a hospital before, and it was my first experience of doctors who handle you without speaking to you or, in a human sense, taking any notice of you. They only put on six glasses in my case, but after doing so they scarified the blisters and applied the glasses again. Each glass now drew out about a dessertspoonful of dark-colored blood. I had aches and pains all over. As I lay down again, humiliated, disgusted and frightened by the thing that had been done to me, I reflected that now at least they would leave me alone. But no, not a bit of it. There was another treatment coming, the mustard poultice, seemingly a matter of routine like the hot bath. Two slatternly nurses had already got the poultice ready, and they lashed it round my chest as tight as a strait-jacket while some men who were wandering about the ward in shirt and trousers began to collect round my bed with half-sympathetic grins. I learned later that watching a patient having a mustard poultice was a favorite pastime in the ward. These things are normally applied for a quarter of an hour and certainly they are funny enough if you don' t happen to be the person inside. For the first five minutes the pain is severe, but you believe you can bear it. During the second five minutes this belief evaporates, but the poultice is bucked at the back and you can' t get it off. This is the period the onlookers enjoy most. During the last five minutes I noted a sort of numbness supervenes. After the poultice had been removed a waterproof pillow packed with ice was thrust beneath my head and I was left alone, I did not sleep, and to the best of knowledge this was the only night of my life—I mean the only night spent in bed—in which I have not slept at all, not even a minute.

单选题One type of person that is common in many countries is the one who always tries to do as little as possible and to get as much 1 return as he can. His opposite, the man who has 2 for doing more than is strictly 3 and who is ready to accept 4 is offered in return, is 5 everywhere. Both these types are entirely different 6 their behavior. The man who 7 effort is always talking about his “ 8 ”. He thinks that society should 9 him a pleasant, easy life. The man who is always doing more than his 10 talks of “duties”. He feels that the 11 is in debt to society. The man who tries to do as 12 as he can is always full of 13 . For instance, if he has 14 to do something, it was because he was 15 by bad luck. His opposite is never 16 busy to take on a(n) 17 piece of work. So it is 18 that if you want something 19 in a hurry go to the busiest man whom you have 20 in.

单选题{{B}}Passage Four{{/B}} The atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)." Unlike some environmental issues, rain forests' depletion has fortunately received significant public and media's attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil {{U}}chops down{{/U}} an area of forests the size of the state of Nebraska. In addition to the Amazon's rain forests, many other forests are being cut down as well.: In Indonesia, Zaire, Papua-new Guinea, Malaysia, Burme, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost. According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute,25 to 50 acres are cut down or burnt to the ground. The world's growing population has been a primary reason of rain forests' destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would alleviate the destruction of the rain forests.
