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 syntheticmaterials. 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 catastrophiclevels 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. 41. According to the passage,the science of the future is likely to be ________ A electronics. B biotechnology. C genetic engineering. D nuclear technology. 42. Organic chemistry helps to produce materials that are ________ A as good as w001. B as good as an insects body. C not as good as natural materials. D better than natural materials. 43. 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. 44. 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. 45. 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.
