Question

Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.

Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects.

Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans.

The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic (災(zāi)難性的) levels unless we develop power sources that are both cheaper and cleaner.

It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.

【解析】

試題分析：文章大意：明天的科學(xué)將是有機化學(xué)和遺傳工程學(xué)的結(jié)合，這就是生物科技。雖然目前有機化學(xué)生產(chǎn)的材料不如天然材料那么好，但是生物科技不會像原子能那樣對人類有害。本文就講了生物科技對人類的好處。

1.B細節(jié)理解題。根據(jù)第一段…combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology.很容易找出答案，明天的科技可能就是生物科技。所以答案選B。

2.D 細節(jié)理解題。 根據(jù)第二段it is still difficult to manufacture anything that has the capacity of wool to conserve (保存) heat and also to absorb moisture.可知，目前來說有機化學(xué)生產(chǎn)的材料不如羊毛保溫吸潮。也就是說不如天然材料好。所以正確答案為D。

3.B 細節(jié)理解題。根據(jù)第三段The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings.可知，生物科技很可能制造出人工的心臟和眼睛來替代人身上患病的器官。所以答案選B。

4.D 細節(jié)理解題。根據(jù)第四段…said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological.可知，1996年Arthur C. Clarke就預(yù)言，我們很快就能生產(chǎn)出既便宜又可再生的能源…所以答案選D。

5.細節(jié)理解題。…nuclear power…Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way.可知，生物科技不會像原子能科技那樣對人類有危害。所以答案選D。
