第1题：
Which is the element responsible for rising wage inequality?
A．Technology as a more irresistible force.
B．Technology and globalization.
C．Technology and automation.
D．Social class in white and blue-collars.
解析：原文中play a role in．．．的意思是“在……中起作用”。根据定位句中的also和bigger可以知道，作者是在拿technology与前一句的globalization作比较，因此两者均是rising wage inequality的原因。故本题答案为B。
第2题：

第3题：
In John Whitehead's opinion, which statement is true?
A．Face recognition technology may interfere with people's privacy.
B．Face recognition technology may enhance the country's constant surveillance.
C．Face recognition technology can be used in the same way wiretaps are used.
D．Face recognition technology can be used after its threat has been removed.
解析：文章最后一段最后一句话“After all，that is exactly what constant surveillance is—the ultimate implied threat of coercion．”这是约翰博士的观点，这项技术威胁到美国每个公民参与社会的权利。所以A、“会干扰人们的隐私”，是正确答案。
第4题：
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?
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.
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8题：
What is this passage mainly about?
A．Disadvantage of face recognition technology.
B．Purposes of face recognition technology.
C．Controversial face recognition technology.
D．Effect of face recognition technology.
解析：文章讲述了警察局对这项技术非常谨慎，为监视摄像机的使用做了充分准备，但收效甚微。所以反对这项技术的人非常多。有人认为它是潜在的威胁，有人认为会侵犯守法公民，但马伦认为这个系统最终会和其他城市，其他州和联邦的执法部门连在一起跟踪罪犯和可疑的恐怖分子。所以说这项技术充满争议。因此选C。
