问题 In the following article, some sentences have been removed. For questions 1 — 5, choose the most suitable one from the list A—G to fit into each of the numbered blank. There are two extra choices which you do not need to use.
    What could be more revealing than a list of one’s search queries? The efficiency of finding what we need on the Web encourages us to quest away—whether we’re researching a car purchase, puzzling out some medical symptoms, wondering what happened to an old friend. "Your search record involves aspirations and dreams," says Marc Rotenberg of the Electronic Privacy Information Center. "It becomes almost a reflection of what’s in one’s head. " And, as we learned recently, when America On-line temporarily released the search history of thousands of customers for the use of researchers, those reflections can be retained by search companies—and, ultimately, exposed.
    【R1】______. Indeed, The New York Times was able to deduce the identity of a 62-year-old widow in Georgia who researched Italian vacations, termites and hand tremors.
    The intimacy of our searches has led Rotenberg and other privacy experts to urge companies like Google, Yahoo and Microsoft not to retain such logs. And a bill proposed by Rep. Edward Markey (Democrat of Massachusetts)would set limits on the length of time such data could be stored. 【R2】______. "Our searches have improved dramatically because we have that data," says Alan Eustace,
    Google’s senior vice president of engineering and research. Furthermore, they contend that without the information, they would be severely obstructed in further improving their products. "If you don’t have such data, there will be significant compromise of the user experience in the future," says Prabhakar Raghavan, Yahoo’s head of research.
    【R3】______. For instance, when a fishing enthusiast types in "bass", he or she will get a different result than the same research from a Paul McCartney fan.
    【R4】______. Yahoo even has a security group referred to informally as "the paranoids", whose motto is "We worry about these things so you won’t have to. "
    【R5】______. The federal government has already expressed interest in such records, and if the data are demanded by the government the companies must turn it over. It’s also not much of a stretch to envision a scene(for example, another terrorist attack)that would pressure the companies to submit to a sweeping request for such logs, just to see if there is sleeper cell or two out there.
    It is possible to search without a trail. So-called anonymizing services can mask your identity when you surf. And some smaller search engines do not keep session logs. The big players, though, are betting that you’ll stick around—because, they say, access to your dreams makes their searches great.
[A]But the detailed records of searches conducted by the users and 657,000 other Americans, copies of which continue to circulate online, underline how much people unintentionally reveal about themselves when they use search engines.
[B]In the AOL case, the records were supposedly anonymous, but since people commonly type in their own names and addresses into search engines, it’s often trivial to judge who is searching.
[C]It is no secret that search engines operated by AOL, Google, Yahoo, and other companies compile data on users such as terms searched for, when they were queried, and what computer and browser was used.
[D]As you would expect, research companies like Google say that protecting the information on those research logs is assigned highest priority.
[E]But the top researchers in the research field argue that that would be ultimately destructive. These experts believe that the information extracted from studying the way individuals search has been crucial in raising the quality of search to its present level.
[F]But even if the companies are flawless in protecting that information, there is still reason to worry.
[G]In particular, these companies hope to introduce schemes by which one’s researching success would be enhanced by previous behavior.
【R3】
选项
答案G
解析 本题空格出现在第四段段首．段落由“空格+例子”构成，例子的内容是：不同的人因为搜索偏好不同，他们搜索相同的词条会得到不一样结果。[G]提到根据各人之前的行为提高搜索成功率的方案，与下文质量提高的例子内容一致，是正确项。
