问题     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 Linkedln. 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 economy of personal information and protecting privacy in an age of big data has yet to be written.
【C19】
选项 A、escape
B、surf
C、improve
D、investigate
答案A
解析 文章第三段提到安格文用假名办信用卡、将邮箱和文件隐藏、关掉网页浏览基本的跟踪功能等做法，说明她想逃离dragnet。A项escape“逃避”符合语义。B项surf意为“网上冲浪”，代入进去意为“尝试上网……”不合句意逻辑。C项improve意为“改善”，改善dragnet不会产生wearisome(令人厌倦)的效果。D项investigate意为“调查”，没有证据表明安格文调查dragnet。
