The Science of the Future

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 (合成的) materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, 1ightness 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 1ie 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.

1、According to the passage, the science of the future is likely to be ______.

A、electronics

B、biotechnology

C、genetic engineering

D、nuclear technology

【正確答案】 B

【答案解析】 本題問的是未來的科學(xué)是屬于什么的?第一段最后一句給出了答案，屬于生物科技，所以選B。

2、Organic chemistry helps to produce materials that are ______.

A、as good as w001

B、as good as an insect’s body

C、not as good as natural materials

D、better than natural materials

【正確答案】 C

【答案解析】 此題為細(xì)節(jié)題，問的是生物化學(xué)能幫助人們生產(chǎn)出什么樣的產(chǎn)品?第二段告訴我們，生物化學(xué)雖然可以幫助我們生產(chǎn)出新的材料，但這些材料的質(zhì)量很難達(dá)到天然產(chǎn)品的程度。這就否定了選項(xiàng)A、B、D，只有選項(xiàng)C為正確答案。

3、According to the Passage, it may soon be possible ______.

A、to make something as good as human skin

B、to produce drugs without side effects

C、to transplant human organs

D、to make artificial hearts and eyes

【正確答案】 D

【答案解析】 本題的答案應(yīng)在第三段里尋找。這段告訴我們，.生物化學(xué)可以幫助我們在未來生產(chǎn)出人工器官，以替代人體中發(fā)病的器官。故選項(xiàng)D為正確答案。

4、In 1996, Arthur C. Clarke predicted that ______.

A、biological power sources would be put into use soon.

B、oil, gas and coal could be repeatedly used in the future.

C、dependence on non-renewable power sources would be reduced soon

D、the Chernobyl disaster would happen in two years.

【正確答案】 A

【答案解析】 本題問的是1996年Arthur’ C. Clarke預(yù)見到了什么?第四段第二句告訴我們，未來人們可以用上生物能源，故選A。

5、What do we learn from the last paragraph?

A、Biotechnology can solve all our future energy problems.

B、Biological power is cheaper than nuclear power.

C、Biological power may not be as dangerous as nuclear power.

D、Biological power will keep all its promises.

【正確答案】 C

【答案解析】 此題問的是讀了最后一段獲得什么信息？本文最后一段談到了生物能源會存在問題，又以原子能指出新能源的危害，但作者最后一句卻暗示新的生物能源不像原子能那樣危險(xiǎn)，故選C。
