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．

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 insect’s 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．
