23.There is a difference between science and technology.Science is a method of answering theoretical questions;technology is a method of solving practical problem.Science has to do with the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships;technology has to do with tools,techniques,and procedures for implementing the finding of science.Another distinction between science and technology has to do with the progress in each.Progress in science excludes the human factor.Scientists,who seek to comprehend the universe and know the truth with the highest degree of accuracy and certainty,cannot pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things.What scientists discover may shock or anger people-as did Darwin's theory of evolution.But even an unpleasant truth is more than likely to be useful;besides,we have the choice of refusing to believe it!But it's hardly so with technology and we do not have the choice of refusing to hear the sonic boom produced by a supersonic aircraft flying overhead;we do not have the choice of refusing to breathe polluted air;and we do not have the choice of living in a non-atomic age.Unlike science progress,technology must be measured in terms of the human factor.The legitimate purpose of technology is to serve people in general,not merely some people;and future generantions,not merely those who presently wish to gain advantage for themselves.Technology must be humanistic if it is to lead to a better world.(10分)23.1Which of the following statements about science is NOT true?(2分)A. Scinece provides answers to theoretical questions.B. Scinece seeks to comprehend the universe.C. Scinece aims to discover the inter-connections of facts and rules that explain them.D. Scinece serves people in general and can be measured in terms of the human factor.
