单选题Long Bus Rides Long bus rides are like television shows. They have a beginning, a middle, and an end with commercials thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard (广告牌) goes by outside the bus window. "Buy Super Clean Toothpaste." "Drink Good"n Wet Root Beer." "Fill up With Pacific Gas." Only if you sleep, which is equal to turning the television set off, are you free from the unending cry of "You Need It! Buy It Now!" The beginning of the ride is comfortable and somewhat exciting, even if you"ve traveled that way before. Usually some things have changed—new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and it"s fun to try to figure it out the first hour or so. If the driver is particularly reckless (鲁莽的) or daring, the ride can be as thrilling as a suspense (悬疑) story. Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you"ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops. The end of the ride is somewhat like the beginning. You know it will soon be over and there"s a kind of expectation and excitement in that. The seat, of course, has become harder as the hours have passed. By now you"ve sat with your legs crossed, with your hands crossed behind your head. The end comes just at the right time. There are just no more ways to sit.

单选题Computers Before the widespread use of computers, managers could not make full use of large amounts of valuable information about a company's activities. The information either reached managers too late or was too expensive to be used. Today, managers are facing a wide range of data processing and information instruments. In place of a few financial controls, managers can draw on computer-based information systems to control activities in every area of their company. On any kinds of performance measures, the information provided by these systems helps managers compare standards with actual results, find out problems, and take corrective action before it is too late to make changes. The introduction of computerized information systems has sharply changed management control in many companies. Even a neighborhood shopkeeper may now use computers to control sales, billing, and other activities. In large companies, electronic data processing systems monitor entire projects and sets of operations. Now, there are about 24 million microcomputers in use in the United States—one for every 10 citizens. It is estimated that by 1996, 61 percent of American managers will be using some sort of electronic work station. In order for managers to be sure that the computer-based information they are receiving is accurate, they need to understand how computers work. However, in most cases they do not need to learn how to program computers. Rather, managers should understand how computerized information systems work; how they are developed; their limitations and costs; and the manner in which information systems may be used. Such an understanding is not difficult to achieve. One research found that business firms were more successful in teaching basic information about computers to business graduates than they were in teaching business subjects to computer science graduates.

单选题 下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。{{B}}第一篇{{/B}} {{B}}The Gene Industry{{/B}} Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes that might be used to mine valuable trace metals from ocean water". They have already demanded and won the right to patent new lifeforms. Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination. Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate "inferior" people and breed a "super-race"? (Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories.) Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate "unfit" babies? Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidney, lives or hands? Wild as these notions may sound, every one has its advocates (and opposers) in the scientific community as well as its striking commercial application.-As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God'? "Broad Scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created".

单选题Libraries Libraries form a vital part of the world's systems of communication and education. They make available knowledge accumulated through the ages. People in all walks of life use library resources in their work. People also turn to libraries to satisfy a desire for knowledge or to obtain material for leisure-time activity. In addition, many people enjoy book discussions, concerts, film programs, lectures, story hours, and a variety of other activities provided by libraries. Libraries also play an important role in preserving a society's cultural heritage (遗产). The library ranks as one of society's most useful service institutions. The contents of libraries have changed so much through the years that the word library itself is, in a sense, inaccurate. The word comes from the Latin word liber, which means book. Today's libraries house many books, of course. However, they also have a wide variety of other materials that communicate, educate, and entertain. These materials include magazines, manuscripts (手稿), newspapers, and computer documents. Audio and visual materials include CDs, audiocassette tapes, videotapes, films, maps, paintings, and photographs. In addition to regular books, a library may have large-type books, books for the blind, and tape recordings of books, called talking books. Librarians keep pace with the changing contents of libraries to serve as many people as possible. Their efforts have turned libraries into multimedia resource centers. The expansion of library contents greatly increases the library's ability to communicate and educate. For example, people interested in classical music can listen to CDs and read books on the topics. Students of agriculture can read magazines and watch videotapes on farming methods. Many people use magazines and newspapers to find the most up-to-date material on current events. In addition to expanding contents, librarians have developed many kinds of libraries to serve the needs of different people. The materials of each kind of library are selected to meet the needs of a specific group of patrons. School libraries have collections that provide the information needed by elementary and high school students. Public libraries tailor their collections to the general public. Government library collections are geared chiefly toward serving the needs of government officials. Thousands of special libraries provide information for professional people, such as advertising specialists, bankers, editors, engineers, lawyers, physicians, and scientists.
