If the online service is free then you are the product, technicians say. Google and Facebook make a【C1】______collecting personal information to help them target their advertisements more【C2】______Free smart-phone apps typically【C3】______all the data they can, such as the person's location or their【C4】______address book. More than ever, individual privacy is【C5】______threat. Julia Angwin, who oversaw a pioneering series of Wall Street Journal articles called "What They Know", starting last year,【C6】______many of the questionable activities that damage privacy—activities that most people know nothing about. Hundreds of unregulated data-agents【C7】______in America, for example, selling personal files to marketing companies. One company runs a fleet of camera—equipped cars that【C8】______the number plates of 1 million vehicles a month, mostly to find those wanted for repossession—【C9】______it sells the data to insurers or private investigators as well. Ms Angwin condemns this shadowy business. Her book tracks her attempts to【C10】______it. She gets a credit card using a fake name; she uses a(n)【C11】______search engine and conceals her e-mail and texts; she leaves LinkedIn. When she turns off basic web-browsing functions that enable tracking she becomes digitally【C12】______. Amazon items appear to be out of【C13】______and she is unable set up an appointment at an Apple store. "My daughter would stand next to me and laugh while I tried to【C14】______a page and browse through all the【C15】______," she writes. Yet "Dragnet Nation" has its【C16】______. It ignores how exciting the【C17】______uses of personal data can be to companies, governments and NGOs. It mixes state scrutiny and privacy-damaging business practices, weakening the study of both. Ms Angwin's analysis of the problems and【C18】______regulatory remedies is shallow, and her attempts to【C19】______the dragnet eventually become wearisome. Her【C20】______is to have made herself a subject in an experiment to avoid the scrutiny found everywhere. But the real story about the e-conomy of personal information and protecting privacy in an age of big data has yet to be written.
单选题
【C1】
【正确答案】
D
【答案解析】解析：空格后提到谷歌和Facebook搜集个人信息的目的：帮助定位广告(target their advertisements)。广告无疑会给他们带来利润，D项fortune有“财富”之意，与make a搭配后表示“赚大钱”，语义符合。
【答案解析】解析：前半句提到带有摄像头的汽车主要是为了找到那些准备要收回的号码(mostly to fred those wanted for repossession)，但空格后说他们将这些数据卖给保险公司或者私家侦探(sells the data to insurers or private investigators)，两句之间含有转折关系。故选B项but。
【答案解析】解析：空格后提到使用这些personal data的主体是companies，governments and NGOs。由本句的exciting可推断，修饰use的单词应是褒义词，且能描述政府等机构使用个人数据的情况。D项legitimate“合法的”，指政府等如果合法使用个人数据会产生积极效果。
单选题
【C18】
【正确答案】
B
【答案解析】解析：从前面的Ms Angwin's analysis of the problems看出，这些问题还处于分析阶段，上文也只涉及她个人所做的一些努力，未提及有效的应对措施，所以后面的remedies只是一种构想。B项potential意为“可能的”，表示可能的补救措施。
【答案解析】解析：本句的表语用于描述空格处词语，因此该词应能体现表语所体现的意义：have made herself a subject in an experiment to avoid the scrutiny found everywhere，安格文将自己当成实验的试验品，努力逃避无所不在的监控具有现实意义，contribution意为“贡献”，符合此处语境，故选B项。
