TheScience of the Future　　Until recently, the "science of thefuture" was supposed to be electronics and artificial intelligence. Todayit seems more and more likely that the next great breakthroughs in technologywill be brought through a combination of those two sciences with organic chemistryand genetic.engineering. This combination is the science of biotechnology.
　　Organic chemistry enables us to producemarvelous synthetic(合成的) materials.However, it is still difficult to manufacture anythingthat 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 thecombination of strength, lightness and flexibility that we find in the bodiesof ordinary insects.
　　Nevertheless, scientists in thelaboratory have already succeeded in "growing" a material that hasmany of the characteristics of human skin. The next step may wellbe"biotech hearts and eyes" which can replace diseased organs inhuman beings. These will not be rejected by the body, as is the case withorgans from humans.
　　The application of biotechnology to energyproduction seems even more promising.In 1996 the famous science-fiction writer,Arthur C．Clarke, many of whose previous predictions have come true, said thatwe may soon be able to develop remarkably cheap and renewable sources ofenergy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we will have to give up our dependenceon non-renewable power sources. Coal, oil and gas are indeedconvenient,However, using them also means creating dangerously high levels ofpollution. It will be impossible to meet the growing demand for energy withoutincreasing that pollution to catastrophic (灾难性的) levels unless we develop power sourcesthat are both cheaper and cleaner.
　　It is attempting to think that biotechnologyor some other "science of the future" can Solve our problems. Beforewe surrender to that temptation we should remember nuclear power. Only a fewgenerations ago it seemed to promise limitless, cheap and safe energy.Todaythose 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.According to the passage, the science of the future is likely to be A．electronic
B．biotechnolog
C．genetic engineerin
D．nuclear technolog
