Science and Technology
There is a difference between science and technology.（46）Science has to do with discovering 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 applying the findings of science.（47）
Progress in science excludes the human factor.Scientists,who seek to understand the universe and know the truth within 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.（48）But even an unpleasant truth is more than likely to be useful;besides,we have the choice of refusing to believe it!But hardly so with technology;we do not have the choice of refusing to hear the sound produced by a supersonic（超音速的）aircraft flying overhead;we cannot refuse to breathe polluted air.（49）The purpose of technology is to serve people——people in general,not merely some people;and future generations,not merely those who presently wish to gain advantage for themselves.
（50）Many people blame technology itself for widespread pollution,resource depletion（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 applications of science and technology do not lead to a better world,what else will?
A Another distinction between science and technology has to do with the progress in each.
B Unlike science,progress in technology must be measured in terms of the human factor.
C What scientists discover may shock or anger people w as did Darwin's theory of evolution.
D Science and technology are different
E We are all familiar with the improper use of technology.
F Science is a method of answering theoretical questions;technology is a method of solving practical problems.
答案：46.F 47.A 48.C 49.B 50.E
解析：
46.F第一句总述了科学和技术是有差别的。缺空后是对两者的分述，因此缺空处也应是对两者的分述，故选F.
47.A承接上文，此处还是在说明科学和技术的不同之处。
48.C第二段针对第一段最后一句，阐述了在人们对待科学和技术的发展上的不同。科学是排除认为因素的，科学家的发现可能会使人们吃惊或发怒，但即使是令人不快的真理也极可能很有用。
49.B缺空前文都是对科学的说明，下文接着讲技术。此处Unlike一转，指出技术是用人为因素来衡量的。
50.E本段在讲技术发展给生活带来的负面影响。因此看选项得知应选E：我们所熟知的是对技术的不当利用。
