单选题 "If the online service is free then you are the product," techies say. Google and Facebook make a fortune by collecting personal information, which helps them target their advertisements more accurately. Free smartphone apps typically suck in all the data they can, such as the person's location or their entire address book. At the same time, governments collect lots of information about everyone, not only through mass surveillance, as the disclosures made by Edward Snowden, but also by gathering common things, such as voter registration and driving-licence records that are then sold on to commercial firms.
More than ever, individual privacy is under threat. Julia Angwin, who oversaw a pioneering series of Wall Street Journal articles called "What They Know", started in 2010, exposes many of the questionable activities that erode privacy—activities that most people know nothing about. Hundreds of unregulated data-brokers exist in America, for example, selling dossiers on people to marketing companies. Individuals have little recourse if they want to examine their files or correct mistakes. One company runs a fleet of camer-aequipped cars that scan the number plates of 1 million vehicles a month, mostly to find those wanted for repossession (收回)—but it sells the data to insurers or private investigators as well.
Ms Angwin decries this shadowy business. Her book tracks her attempts to wrest freedom from it. She gets a credit card using an alias; she uses an anonymous search engine and encrypts (加密) her e-mail and texts; she leaves LinkedIn. When she turns off basic web-browsing functions that enable tracking (using so-called cookies) she becomes digitally paralysed. Amazon items appear to be out of stock and she is unable to set up an appointment at an Apple store. "My daughter would stand next to me and laugh while I tried to load a page and navigate through all the permissions," she writes.
Yet "Dragnet (搜索网) Nation" has its faults. It ignores how exciting the legitimate uses of personal data can be to companies, governments and NGOs. It mixes state surveillance (监控) and privacy-eroding business practices, weakening the study of both. Ms Angwin's analysis of the problems and potential regulatory remedies is shallow, and her attempts to escape the dragnet eventually become wearisome. Her contribution is to have made herself a guinea pig in an experiment to avoid ubiquitous surveillance. But the real story about the economy of personal information and protecting privacy in an age of big data has yet to be written.

单选题 What does the author mean by saying "...you are the product"?

A. Companies make a big fortune from your organs.
B. Companies use your accurate data to advertise you.
C. Companies sell and buy your personal information.
D. You are sold on the Internet by Google and Facebook.

【正确答案】 C

【答案解析】[解析] 第1段第1句提到，技术人员说：“如果网上服务是免费的，那么你就是产品。”接着下一句作出具体说明，即公司通过买卖个人信息来赚钱。由此可见，此处所说的产品就是你的个人信息，而不是A所说的your organs(你的器官)，故排除A。B是对第1段第2句的错误理解，该句说的是通过个人信息准确地投放广告，而不是对“你”进行宣传，故排除B。文中没有提到谷歌和脸谱在网上出售“你”，故D也不符合题意，予以排除。

单选题 What can we learn from the second paragraph?

A. Julia Angwin is a well-known editor of Wall Street Journal.
B. The series of articles "What They Know" started in 2010.
C. Wall Street Journal exposes many unregulated data-brokers.
D. Wall Street Journal knows nothing about activities that erode privacy.

【正确答案】 B

【答案解析】[解析] 第2段第2句提到，朱莉娅·安格文监管着《华尔街日报》2010年首次创办的系列文章《他们知道什么》，披露了其中许多侵害我们隐私的可疑行为，而大多数人对这些行为一无所知。其中的started in 2010修饰“What They Know”，即《他们知道什么》系列文章是从2010年开始的，故B符合文意，为答案。A的说法没有依据，文中没有提到朱莉娅·安格文是《华尔街日报》的编辑。C和D都属于张冠李戴，文中说的是朱莉娅·安格文披露了许多不守法的数据经理人，故排除C，再由破折号后的activities that most people know nothing about可以排除D。

单选题 What does Ms Angwin do to protect her privacy?

A. She no longer uses credit card, and pays in cash instead.
B. She turns off basic web-browsing functions called cookies.
C. She adds secure passwords to her e-mail and texts.
D. She lies about her credit card records to her net friends.

【正确答案】 C

【答案解析】[解析] 第3段第3句提到，她(安格文)用化名办信用卡、使用匿名搜索引擎、给邮件和文件加密、退出“领英”。C是对句中提到的encrypts her e-mail and texts的同义转述，故为答案。A和D是对she gets a credit card using an alias的错误理解，文中说的是她用化名办信用卡，而不是说她完全不用信用卡或谎称自己的信用卡记录，故排除A和D。由第4句可知，基本网页浏览功能与信息记录程序不是同一样事物，故B也不符合文意，予以排除。

单选题 Julia Angwin's struggling with privacy-eroding activities ______.

A. turns out to be a failure
C. is admired by the author
B. is supported by her daughter
D. ignores regulatory remedies

【正确答案】 A

【答案解析】[解析] 第3段第4句提到，当她(即朱莉娅·安格文)关掉可以用来进行追踪的基本的网页浏览功能(使用所谓的信息记录程序)时，她陷入了数据瘫痪。由此可见，她与侵害个人隐私行为的斗争最终并未成功，故A符合题意。由第3段最后一句提到的My daughter would stand next to me and laugh...可以排除B。文中并未提及作者对朱丽娅·安格文与侵害个人隐私行为作斗争的看法，故排除C。D是利用最后一段倒数第三句中的regulatory remedies设置的干扰。

单选题 The author thinks that Julia Angwin ______.

A. has become the victim of the big data age
B. has done something harmful to the economy
C. has written about a lot of habits of guinea pigs
D. doesn't know well of the problems with Dragnet

【正确答案】 D

【答案解析】[解析] 最后一段第4句提到，安格文对这些问题及可能的法律补救措施的分析都较肤浅，其中的the problems即指前文提到的网络世界存在的问题，D中的doesn't know well of是对文中Ms Angwin's analysis...is shallow的同义转述，故D符合题意，为答案。A、B和C都是利用文中出现的只字片语设置的干扰。
