Science andTechnology

There is adifference between science and technology.______(46)Science has to do withdiscovering the facts and relationships between observable phenomena in natureand

with establis- hingtheories that serve to organize these facts and relationships;technology has todo with tools, techniques,and procedures for applying the findings of

science.______(47)

Progress in scienceexcludes the human factor.Scientists,who seek to understand the uni-verse andknow the truth within the highest degree of accuracy and certainty,cannot

pay attention totheir own or other peoples likes or dislikes or to popular ideas about thefitness of things.______(48)But even an unpleasant truth is more than likely tobe

useful;besides,wehave the choice of refusing to believe it!But hardly so with technology;we donot have the choice of refusing to hear the sound produced by a supersonic

（超音速的）aircraftflying overhead; we cannot refuse to breathe polluted air.______(49)The purposeof technology is to serve peo-

ple—people ingeneral,not merely some people;and future generations,not merely those whopresently wish to gain advantage for themselves.

_______(50)Manypeople blame technology itself for widespread pollution,resource de-pletion（枯竭）and even social decay in general—so much so that the promise of

technology is“obscured”.That promise is a cleaner and healthier world.If wise applicationsof science and technology do not lead to a better world,what else will?______(46)
