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 establis- hing 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 uni-verse and know the truth within the highest degree of accuracy and certainty,cannot pay attention to their own or other peoples 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 peo-
ple—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 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 applications of science and technology do not lead to a better world,what else will?______(49)
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—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：B解析：第一段第一句话就说科学和技术不一样。很自然，下面应该具体讲一下有什么不同。F讲了它们之间的一个不同之处：科学是回答理论问题的方法，技术是解决具体问题的方法。
another distinction表明，这句话前面应该讲到过类似的差别。事实上，第一段的全部内容都是在讲科学和技术之间的差别，第二句话，即46空讲了一点，第三句话又讲了一点，接下来，作者很自然地用another distinction来介绍另外一个差别。
整个第二段是对第一段最后一句话47空的发展，也就是科学和技术的一个不同和它们各自的进步有关。第二段的第一句话讲了科学的进步排除了人的因素，进而解释说科学家力图了解宇宙，尽可能精确地寻求真理，不可能考虑他们自己或者他人的喜好，或者一般人认为他们的发现是否合适。下面，即48空，是一个例子：科学家的发现可能会使人们感到震惊或发怒，如达尔文的进化论。该理论的提出因为和上帝造人的教义相悖，在当时使教会大为恼怒，甚至禁止宣传。
如前所说，整个第二段都是讲科学和技术的差别，前半段主要讲科学，从“But hardly so with technology”开始，作者转向谈技术。在这一句里作者更明确地把科学和技术在人的因素这个方面的差别重复一下。
这句话是最后一段的第一句，可以说是本段的主题句。技术应服务于人类，但技术使用不当带来的负面影响大家都是很熟悉的。 -

第5题：
A.afraid of technology
B.skilled in technology
C.ignorant of technology
D.incompetent in technology答案：B解析：原文中说MacDonald likely got a boost from techies ，即MacDonald得到techies的追捧，并且techies后面跟了一个定语从句eager to see the Internet pass this daring test of its networking power ，这些人渴望这次网络试验成功以证明互联网的力量强大，因此答案应为B项“擅长技术”的人。A项“害怕技术”、C项“对技术一窍不通”和D项“对技术无能为力”均在逻辑上不符合语境，因为如果这样的话，他们不会对物物交换这样的新兴网络技术感兴趣。techie相当于中文里的“技术狂”。故本题选B。参考译文：上周末凯尔·麦克唐纳在蒙特利尔举行了一场聚会来庆祝他乔迁新居，而这个新家是他用一个红色的曲别针换来的。这件事开始于一年前，凯尔通过物物交换，用这枚曲别针换来了越来越值钱的东西，包括一个露营用的炉子以及在菲尼克斯一座公寓的免费居住权。由于先前他已经声明过他的目标是换一套房子，凯尔吸引了许多欣赏他大胆行为的人，并且这些乐于证明互联网强大力量的技术狂为凯尔提供了许多帮助。“我的座右铭是‘小起点，大思考，多乐趣’，”26岁的凯尔说，“我真正地把我的努力都放在了创造力上，而不是放在业务本身。” -

问答题Practice 2Directions: You are asked to write in no less than 150 words about the title of Advanced Technology Is Changing the Way We Learn. You should base your composition on the following requirements. 1. Give examples to show how advanced technology has changed the way we learn. 2. Tell the advantages of the application of advanced technology in learning.正确答案：
【参考范文】
Advanced Technology Is Changing the Way We Learn With the development of technology, every aspect of our life has been changed and the way we learn is no exception. The use of computer is a good example. With the help of the computer and Internet we can learn a great amount of knowledge without going to the classroom and asking professors to answer the questions, and we can also get access to the books we want to read in various libraries through the Internet.
With the application of advanced technology we can learn more easily and efficiently. For example, when we meet some new words while reading English articles, we don’t have to look the new words up in a dictionary. With a click, the computer’s electronic dictionary will immediately tell us the meaning of the new words. In addition, the computer can help us analyze our research data and finish papers more easily.
In a word, advanced technology has changed the way we learn and has helped us a lot in our study.解析： 暂无解析 -
