在英语日益重要的今天，学好英语成了大多数学生的首要目标。为帮助大学生高效的学习英语。特收集以下练习：
The simple act of surrendering a telephone number to a store clerk may not seem harmful--so much so that many consumers do it with no questions asked. Yet that one action can set in motion a cascade of silent events, as that data point is acquired, analyzed, categorized, stored and sold over and over again. Future attacks on your privacy may come from anywhere, from anyone with money to purchase that phone number you surrendered. If you doubt the multiplier effect, consider your e-mail inbox. If it's loaded with spam, it's undoubtedly because at some point in time you unknowingly surrendered your e-mall to the wrong Web site.
Do you think your telephone number or address is handled differently? A cottage industry of small companies with names you've probably never heard of--like Acxiom or Merlin--buy and sell your personal information the way other commodities like corn or cattle futures are bartered. You may think your cell phone is unlisted, but if you've ever ordered a pizza, it might not be. Merlin is one of many commercial data brokers that advertises sale of unlisted phone numbers compiled from various sources--including pizza delivery companies. These unintended, unpredictable consequences that flow from simple actions make privacy issues difficult to grasp, and grapple with.
In a larger sense, privacy also is often cast as a tale of Big Brother--the government is watching you or An big corporation is watching you. But privacy issues don’t necessarily involve large faceless institutions: A spouse takes a casual glance at her husband's Blackberry, a co-worker looks at e-mall over your shoulder or a friend glances at a cell phone text message from the next seat on the bus. while very little of this is news to anyone--people are now well aware there are video cameras and Internet cookies everywhere--there is abundant evidence that people live their lives ignorant of the monitoring, assuming a mythical level of privacy. People write e-mails and type instant messages they never expect anyone to see. Just ask Mark Foley or even Bill Gates, whose e-mails were a cornerstone of the Justice Department's antitrust case against Microsoft.
And polls and studies have repeatedly shown that Americans are indifferent to privacy concerns. The general defense for such indifference is summed up a single phrase: I have nothing to hide. If you have nothing to hide, why shouldn't the government be able to peek at your phone records, your wife see your e-mail or a company send you junk mail? It's a powerful argument, one that privacy advocates spend considerable time discussing and strategizing over.
It is hard to deny, however, that people behave different when they're being watched. And it is also impossible to deny that Americans are now being watched more than at any time in history.

【文章概要】
本文以小我无意泄露电话号码和电子邮件为例引出对隐私问题的切磋。首段指削发单无意识地泄露小我信息的行为可能事后会给自己带来麻烦;第2段讲述某些小 公司操作泄露小我信息来获利，使得隐私成为一个棘手的问题;第3段进一步提到隐私问题不必然只涉及大机构，隐私在日常糊口中就可能有意无意地受到加害;第4段讲到美国人对隐私问题的立场及作者对此的观点;第5段作小结指出美国人正面临着更多的看管。
【谜底解析】
1.[C]细节判定题。首段第l句提到泄露电话号码的例子，第2、3句指出这一行为可能带来的麻烦，故选C。A、B自己正确但只勾留在例子自己，并没有指明举例要剖明的问题;D在文中没有说起。
2.[B]细节揣度题。按照Acxiom和Merlin定位到第2段第2旬。该句第2个破折号说了然这两家公司的性质，指出他们生意小我信息就像生意玉米和牛期货证券一样，故选8。文中提到Merlin公司出售那些未挂号过的电话号码，这些号码汇编来历多样，A只是操作原文个体单词设置的干扰项;文中 只是嗣魅这些公司生意小我信息的体例就像在市场生意玉米的体例一样，故C错;D“破解如窃取小我信息的犯罪过为”在文中没有说起。
3.[D]段落细节题。由第3段第2句可知A错误;由该段倒数2、3句可知人们对隐私受加害并没有多深的意识，故B也错：But一句指出隐私问题并不必然只涉及大机构，冒号后所列举的例子即是对此不雅概念的撑持，可见C的说法也是不正确的;末旬指出司法部控诉微软公司就是操作比尔·盖茨的邮件为证据，故D正确。
4.[A]推理判定题。第4段第l句指出发芽拜访和研究证实美国人对隐私问题隔山观虎斗，但按照后文持续几个假设问句可以揣度出。美国人现实上很关注他们的隐私问题，故C错误;B只是一种概况现象;文中没有说起他们对隐私的关注是否“迷惑”，D也不合错误。
5.[B]不雅概念立场题。文章首段就提到了隐私无意间的泄露可能会带来的麻烦，接下来几段分袂从小我信息被滥用、隐私问题无处不在、美国人对隐私的立场等方面声名，在当今时代，因为通信手艺的发家，小我隐私的呵护问题越来越复杂.是以人们对隐私问题应给以更多的正视，故选B。A、C说法过分绝对;D项也不能概述作者的不雅概念。
