单选题What are those of us who have chosen careers in science and engineering able to do about our current problems? First, we can help destroy the false impression that science and engineering have caused the current world trouble. On the contrary, science and engineering have made vast contributions to better living for more people. Second, we can identify the many areas in which science and technology, more considerably used, can be of great service in the future than in the past to improve the quality of life. While we can make many speeches, and pass many laws, the quality of our environment will be improved only through better knowledge and better application of that knowledge. Third, we can recognize that much of the dissatisfaction we suffer today results from our very successes of former years. We have been so greatly successful in attaining material goals that we are deeply dissatisfied that we cannot attain other goals more rapidly. We have achieved a better life for most people, but we are unhappy that we have not spread it to all people. We have reduced many sources of environmental disasters, but we are unhappy that we have not conquered all of them. It is our raised expectations rather than our failures which now cause our distress. Granted that many of our current problems must be cured more by social, political, and economic instruments than science and technology, yet science and technology must still be the tools to make further advances in such things as clean air, clean water, better transportation, better medical care, more adequate welfare programs, purer food, conservation resources, and many other areas.

单选题{{B}}Questions 16-20 are based on the following passage:{{/B}} The Xinhua bookstore chain, China's largest official publishing enterprise, has become a surprising flash point for interest among foreign venture capital investors. "We are actively promoting the process of shareholding reform. Every day, we receive lots of offers from domestic and foreign investors interested in getting involved and may pick one or two to do so in the next two to three months," Zhang Yashan, the leading cadre of the head store's office said. According to a company insider who requested anonymity, several securities firms are overseeing Xinhua bookstore's reform and the company could list on the domestic stock market once reforms are repotted to the government in May and then completed. The source would not reveal the specific names of the firms involved or details of the reform. "We will stipulate that we must remain the majority shareholder, but we will welcome all kinds of investment, including foreign capital, to establish a shareholding enterprise. We hope the No. 2 shareholder will be a foreign enterprise," the source said. In keeping with its World Trade Organization entry promises, China must allow foreign investment in domestic publication retailers by the end of this year.

单选题By education, I mean the influence of the environment upon the individual to produce a permanent change in the habits of behavior, of thought and of attitude. It is in being thus susceptible to the environment that man differs from the animals, and the higher animals from the lower. The lower animals are influenced by the environment but not in the direction of changing their habits. Their instinctive responses are few and fixed by heredity. When transferred to an unnatural situation, such an animal is led astray by its instincts. Thus the "ant-lion" whose instinct implies it to bore into loose sand by pushing backwards with abdomen, goes backwards on a plate of glass as soon as danger threatens, and endeavors, with the utmost exertions to bore into it. It knows no other mode of flight, "or if such a lonely animal is engaged upon a chain of actions and is interrupted, it either goes on vainly with the remaining actions(as useless as cultivating an unsown field)or dies in helpless inactivity". Thus a net-making spider which digs a burrow and rims it with a bastion of gravel and bits of wood, when removed from a half finished home, will not begin again, though it will continue another burrow, even one made with a pencil. Advance in the scale of evolution along such lines as these could only be made by the emergence of creatures with more and more complicated instincts. Such beings we know in the ants and spiders. But another line of advance was destined to open out a much more far-reaching possibility of which we do not see the end perhaps even in man. Habits, instead of being born ready-made(when they are called instincts and not habits at all), were left more and more to the formative influence of the environment, of which the most important factor was the parent who now cared for the young animal during a period of infancy in which vaguer instincts than those of the insects were molded to suit surroundings which might be considerably changed without harm. This means, one might at first imagine, that gradually heredity becomes less and environment more important. But this is hardly the truth and certainly not the whole truth. For although fixed automatic responses like those of the insect-like creatures are no longer inherited, although selection for purification of that sort is no longer going on, yet selection for educability is very definitely still of importance. The ability to acquire habits can be conceivably inherited just as much as can definite responses to narrow situations. Besides, since a mechanism—is now, for the first time, created by which the individual(in contradiction to the species)can be fitted to the environment, the latter becomes, in another sense, less not more important. And finally, less not the higher animals who possess the power of changing their environment by engineering feats and the like, a power possessed to some extent even by the beaver, and preeminently by man. Environment and heredity are in no case exclusive but always-supplementary factors.

单选题The rise of multinational corporations, global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR. Surprisingly, since modern PR was largely an American invention, the U.S. leadership in public relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world"s top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporate planning activities, compared to about one-third of U.S. companies. It may not be long before London replaces New York as the capital of PR. Why is America lagging behind in the global PR race? Firstly, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, American lags behind their European and Asian counterparts in knowing a second language. Less than 5 percent of Burson-Marshall"s U. S. employees know two languages. Ogilvy and Mather has about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal . Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist , publications not often read in this country. Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable News Network). Turner recently announced that the word "foreign" would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the world so interdependent that there is no longer any such thing as foreign.
