According to the passage, the science of the future is______.
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 excellent 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, 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.
选项
A、as good as wool
B、as good as an insect’s body
C、not as good as some natural materials
D、as good as humans’ skin
答案
C
解析
客观推断题。此道题目考查的是考生对于录音当中细节的快速判断和筛除的能力,我们可以听到“However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture.”由此可以断定正确答案是C。
