单选题 In recent years a new farming revolution has begun, one that involves the{{U}} (21) {{/U}}of life at a fundamental level — the gene. The study of genetics has{{U}} (22) {{/U}}a new industry called biotechnology. As the name suggests, it{{U}} (23) {{/U}}biology and modem technology through such techniques as genetic engineering. Some of the new biotech companies specialize{{U}} (24) {{/U}}agriculture and are working feverishly to duplicate seeds that give a high yield, that{{U}} (25) {{/U}}diseases, drought and frost, and that reduce the need for{{U}} (26) {{/U}}chemicals.{{U}} (27) {{/U}}such goals could be achieved, it would be most beneficial. But some have raised concerns about genetically engineered crops. In nature, genetic diversity is created within certain space. A rose{{U}} (28) {{/U}}be crossed with a different kind of rose, but a rose will never cross with a potato. Genetic engineering,{{U}} (29) {{/U}}, usually involves taking genes from one species and inserting them into{{U}} (30) {{/U}}in an attempt to transfer a desired characteristic. This could mean,{{U}} (31) {{/U}}, selecting a gene which leads to the production of a chemical with anti-freeze quality from an arc- tic fish, and inserting{{U}} (32) {{/U}}into a potato or strawberry to make it frost-resistant. In essence, then, biotechnology allows humans to{{U}} (33) {{/U}}the genetic walls that separate species. Like the green revolution,{{U}} (34) {{/U}}some call the gene revolution contributes to the problem of genetic uniformity — some say even more so that geneticists can employ techniques{{U}} (35) {{/U}}as cloning and{{U}} (36) {{/U}}culture, processes that produce perfectly{{U}} (37) {{/U}}copies. Concerns about the erosion of biodiversity, therefore,{{U}} (38) {{/U}}. Genetically altered plants, however, raise new issues, such as the effects that they may have{{U}} (39) {{/U}}us and the environment. "We are flying blindly into a new era of agricultural biotechnology with high hopes, few constraints, and{{U}} (40) {{/U}}idea of the potential outcomes," said science writer Jeremy Rifkin.

单选题{{B}}Passage 3{{/B}} Wise compromise is one of the basic principles and virtues of the British. If a continental greengrocer asks 14 shillings (or crown, or francs) for a bunch of radishes, and his customer offers 2, and finally they strike bargain agreeing on 6 shillings, this is just the low continental habit of bargaining; on the other hand if the British dock-workers or any other workers claim a rise of 4 shillings per day, and the employers first flatly refuse even a penny, but after a six weeks' strike they agree to a rise of 2 shillings a day--that is yet another proof of the British genius for compromise. Bargaining is a repulsive habit; compromise is one of the highest human virtues--the difference between the two being that the first is practiced on the Continent, the latter in Great Britain. The genius for compromise has another aspect, too. It has a tendency to unite together everything which is bad. English club life, for instance, unites the liabilities of social life with the boredom of solitude. An average English house combines all the curses of civilization with the ups and downs of life in the open. It is all right to have windows, but you must not have double windows because double would indeed stop the wind from blowing right into the room, and after all, you must be fair and give the wind a chance. It is all right to have central heating in an English home, except in the bathroom, because that is the only place where you are naked and wet at the same time, and you must give British germs a fair chance. The open fire is an accepted, indeed a traditional institution. You sit in front of it and your face is hot whilst your back is cold. It is a fair compromise between two extremes and settles the problems of how to burn and catch cold at the same time. English spelling is a compromise between documentary expressions and an elaborate code-system; spending 3 hours in a queue in front of a cinema is a compromise between entertainment and asceticism; the English weather is a fair compromise between rain and fog; to employ an English charwoman is a compromise between having a dirty house and cleaning it yourself; Yorkshire pudding is a compromise between a pudding and the county of Yorkshire.

单选题Reading to oneself is modem activity which was almost unknown to the scholars of the classical and medieval (between AD 1100 and 1500) worlds, while during the fifteenth century the term "reading" undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace. One should be careful, however, in assuming that silent reading came about simply because reading aloud is distraction to others. Examination of factors related to the historical development of silent reading reveals that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character. The last century saw a steady gradual increase in literacy, and thus in the number of readers. As readers increased, so the number of potential listeners decreased, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers. Towards the end of the century there was still considerable argument over whether books should be used for information or treated respectfully, and over whether the reading of materials such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by book and magazines for a specialized readership on the other. By the end of the century students were being recommended to adopt attitudes to books and to use skills in reading them which were inappropriate, if not impossible, for the oral reader. The social, cultural, and technological changes in the century had greatly altered what the term "reading" implied.

单选题Revolutionary innovation is now occurring in all scientific and technological fields. This wave of unprecedented change is driven primarily by advances in information technology, but it is much larger in scope. We are not dealing simply with an Information Revolution but with a Technology Revolution. To anticipate developments in this field, the George Washington University Forecast of Emerging Technologies was launched at the start of the 1990s. We have now completed four rounds of our Delphi survey — in 1990, 1992, 1994, and 1996 — giving us a wealth of data and experience. We now can offer a reasonably clear picture of what can be expected to happen in technology over the next three decades. Time horizons play a crucial role in forecasting technology. Forecasts of the next five to ten years are often so predictable that they fall into the realm of market research, while those more than 30 or 40 years away are mostly speculation. This leaves a 10- to 20-year window in which to make useful forecasts. It is this time frame that our Forecast addresses. The Forecast uses diverse methods, including environmental scanning, trend analysis, Delphi surveys, and model building. Environmental scanning is used to identify emerging technologies. Trend analysis guides the selection of the most important technologies for further study, and a modified Delphi survey is used to obtain forecasts. Instead of using the traditional Delphi method of providing respondents with immediate feed- back and requesting additional estimates in order to arrive at a consensus, we conduct another survey after an additional time period of about two years. Finally, the results are portrayed in time periods to build models of unfolding technological change. By using multiple methods instead of relying on a single approach, the Forecast can produce more reliable, useful estimates. For our latest survey conducted in 1996, we selected 85 emerging technologies representing the most crucial advances that can be foreseen. We then submitted the list of technologies to our panel of futurists for their judgments as to when (or if) each technological development would enter the mainstream, the probability that it would happen, and the estimated size of the economic market for it. In short, we sought a forecast as to when each emerging technology will have actually "emerged".
