单选题Once upon a time there lived a beautiful young woman and a handsome young man. They were very poor, but as they were deeply in love, they wanted to get married. The young people's parents shook their heads. "You can't get married yet," they said. "Wait till you get a good job with good prospects." So the young people waited until they found good jobs with good prospects and they were able to get married. They were still poor, of course, but large organizations lent him the money he needed to buy a house, some furniture, all the latest electrical appliances and a car. The couple lived happily ever after, paying off debts for the rest of their lives. And so ends another modern romantic fable. We live in a materialistic society and when we grow old enough to earn a living, it does not surprise us to discover that success is measured in terms of the money you earn. We spend the whole of our lives keeping up with the Joneses. If we buy a new car, we can be sure that Jones will go on better and get two new cars: one for his wife and one for himself. The most amusing thing about this game is that the Joneses and all the neighbors who are struggling frantically to keep up with them are spending borrowed money kindly provided, at a suitable rate of interest, of course, by friendly banks, insurance companies, etc. It is not only in affluent societies that people are obsessed with the idea of making more money. Consumer goods are desirable everywhere and modern industry deliberately sets out to create new markets. Gone are the days when industrial goods were made to last forever. The wheel of industry must be kept turning. "Built-in obsolescence" provides the means: goods are made to be discarded. Cars get tinnier and tinnier. You no sooner acquire this year's model than you are thinking about its replacement.

单选题 In the past, American colleges and universities were created to serve a dual purpose to advance learning and to offer a chance to become familiar with bodies of knowledge already discovered to those who wished it. To create and to impart, these were the distinctive features of American higher education prior to the most recent, disorderly decades of the twentieth century. The successful institution of higher learning had never been one whose mission could be defined in terms of providing vocational skills or as a strategy for resolving societal problems. In a subtle way Americans believed higher education to be useful, but not necessarily of immediate use. Another purpose has now been assigned to the mission of American colleges and universities. Institutions of higher learning-public or private-commonly face the challenge of defining their programs in such a way as to contribute to the service of the community. This service role has various applications. Most common are programs to meet the demands of regional employment markets, to provide opportunities for upward social and economic mobility, to achieve racial, ethnic, or social integration, or more generally to produce "productive" as compared to "educated" graduates. Regardless of its precise definition, the idea of a service-university has won acceptance within the academic community. One need only be reminded of the change in language describing the two-year college to appreciate the new value currently being attached to the concept of a service-related university. The traditional two-year college has shed its pejorative "junior" college label and is generally called a "community" college, a clearly value-laden expression representing the latest commitment in higher education. Even the doctoral degree, long recognized as a required "union card" in the academic world, has come under severe criticism as the pursuit of learning for its own sake and the accumulation of knowledge without immediate application to a professor's classroom duties. The idea of a college or university that performs a triple function-- communicating knowledge to students, expanding the content of various disciplines, and interacting in a direct relationship with society--has been the most important change in higher education in recent years. The novel development, however, is often overlooked. Educators have always been familiar with those parts of the two-year college curriculum that have a "service" or vocational orientation. It is important to know this. But some commentaries on American postsecondary education tend to underplay the impact of the attempt of colleges and universities to relate to, if not resolve, the problems of society. What's worse, they obscure a fundamental question posed by the service-university--what is higher education supposed to do?

单选题The principle of the social character of the school as the basic factor in the moral education given may be also applied to the question of methods of instruction, not in their details, but in their general spirit. The emphasis then fells upon instruction and giving out, rather than upon absorption and mere learning. We fail to recognize how essentially individualistic the latter methods are, and how unconsciously, yet certainly and effectively, they react into the child's ways of judging and of acting. Imagine forty children all engaged in reading the same books, and in preparing and reciting the same lessons day after day. Suppose this process constitutes by far the larger part of their work, and that they are continually judged from the standpoint of what they are able to take in a study hour and reproduce in a recitation hour. There is next to no opportunity for any social division of labor. There is no opportunity for each child to work out something specifically his own, which he may contribute to the common stock, while he participates in the productions of others. All are set to do exactly the same work and turn out the same products. The social spirit is not cultivated, in fact, in so far as the purely individualistic method gets in its work, it atrophies for lack of use. The child is born with a natural desire to give out, to do, to serve. When this tendency is not used, when conditions are such that other motives are substituted, the accumulation of an influence working against the social spirit is much larger than we have any idea of, especially when the burden of work, week after week, and year after year, falls upon this side. But lack of cultivation of the social spirit is not all. Positively individualistic motives and standards are inculcated. Some stimulus must be found to keep the child at his studies. At the best this will be his affection for his teacher, together with a feeling that he is not violating school rules, and thus negatively, if not positively, is contributing to the good of the school. I have nothing to say against these motives so far as they go, but they are inadequate. The relation between the piece of work to be done and affection for a third person is external, not intrinsic It is therefore liable to break down whenever the external conditions are changed. Moreover, this attachment to a particular person may become so isolated and exclusive as to be selfish in quality. In any case, the child should gradually grow out of this relatively external motive into an appreciation, for its own sake, of the social value of what he has to do, because of its larger relations to life, not pinned down to two or three persons. But, unfortunately, the motive is not always at this relative best, but mixed with lower motives which are distinctly egoistic. Fear is a motive which is almost sure to enter in, not necessarily physical fear, or fear of punishment, but fear of losing the approbation of others; or fear of failure, so extreme as to be morbid and paralyzing. On the other side, emulation and rivalry enter in. Just because all are doing the same work, and are judged(either in recitation or examination with reference to grading and to promotion)not from the standpoint of their personal contribution, but from that of comparative success, the feeling of superiority over others is unduly appealed to, while timid children are depressed. Children are judged with reference to their capacity to realize the same external standard. The weaker gradually lose their sense of power, and accept a position of continuous and persistent inferiority. The effect upon both self-respect and respect for work need not be dwelt upon. The strong learn to glory, not in their strength, but in the fact that they are stronger.
