7．When you're surfing the Internet on your laptop from your dorm or home，do you know your personal details are being gathered secretly？And would you be surprised to know the information may be sold cheaply to advertisers and marketers？
According to an investigation by The Wall Street Journal，all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letter-to record the computer user's age，gender，location，favorite movies and hobbies．
The newspaper reports that Lotame Solutions Inc．，a New York company，uses sophisticated software called a'"beacon"to capture what people are typing on a website．
Lotame packages the data into profiles （個(gè)人資料） about individuals，only without their names，and sells the profiles to companies seeking customers．Such data may be sold for a few dollars．
The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the Internet．
The"cookie"，a tiny text file put on your PC by websites or marketing firms，which might be used to remember your preferences for one site or to track you across many sites，is already old news．There are new and more complex tools such as"beacons"which scan in real time what people are doing on a webpage．'These beacons instantly assess the Internet user's location，income，shopping interests and even medical conditions．
Millions of Internet users around the world also face great threats．Their private，sensitive，personal and business information is being gathered and sold without their knowledge．
Companies insist that the information they gather is anonymous （匿名的） and the data is used harmlessly．But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were．installing （安裝） intrusive （侵入的） files on visitors'computers．These include MSN．com and Yahoo．com．

分析 本文是科技說明文，文章告訴我們當(dāng)我們在宿舍或在家上網(wǎng)時(shí)，我們的個(gè)人信息包括一些隱私的活敏感的信息正在被悄悄的收集并銷售；一些公司運(yùn)用一些設(shè)備如"信標(biāo)"能夠即時(shí)獲取網(wǎng)絡(luò)用戶的信息；而銷售從網(wǎng)上利益收集的個(gè)人信息已經(jīng)成為一個(gè)迅速崛起的行業(yè)；雖然這些公司宣稱銷售的信息是匿名信息，但是這種技術(shù)如此強(qiáng)大甚至一些大的公司獨(dú)不知道被入侵．
解答 57．A 主旨大意題．文章第一段提出了問題"When you're surfing the Internet on your laptop from your dorm or home，do you know your personal details are being gathered secretly？（當(dāng)你在宿舍或在家上網(wǎng)時(shí)，你知道你的個(gè)人信息正在被悄悄的收集嗎？"，在隨后的各段中分析如何被悄悄的收集，由此判斷本文的目的在于向讀者解釋自己的信息如何在上網(wǎng)的過程中被泄露的，所以答案選擇A．
58．B．細(xì)節(jié)理解題．根據(jù)文章中第四段的最后一句"Such data may be sold for a few dollars．（這些數(shù)據(jù)也許能買幾美元．）可以判斷是為了賺錢而通過網(wǎng)絡(luò)獲取信息，所以答案選擇B．
