Imagine you went to a restaurant with a date; had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, "Hey Joe, how are you? Mary is over there in the seat you sat in last time. Would you like to join her for dinner again?" Then you find out that your burger has been cooked and your drink is on the table. Forget the fact that you are with another date and are on a diet that doesn't include burgers. Sound a little bizarre? To some, this is restaurant equivalent of the Internet.The Net's ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you—some of which you may notwant them to have.

Are you aware that almost every time you access a website you get a “cookie”? Unfortunately, it’s not the Mrs. Reid’s type. A cookie on the Internet is a computer code sent by the site to your computer—usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about your interaction, including where you visit, how long you stay there, how frequently you return to certain pages, and even your electronic address. Fill out a survey to collect free information or samples, and marketers know even more about you—like your name, address, and any other information you provide. While this may sound scary enough, cookies aren’t even the latest in technology. A new system called I-librarian Alexa—named for the legendary third century B.C. library in Alexandria, Egypt—does even more. While cookies track what you are doing at one site, Alexa collects data on all your Web activity, such as which sites you visit next, how long you stay there, whether you click on ads，etc. All thisinformation is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don’t even know that you are giving it.

1.[C] 推理判断题。第1段中，乔另约了一名新女友去餐馆，餐馆服务员却招呼他坐在上次约会的女友身边，并且为他准备了与上次同样的食品，包括他节食忌用的汉堡，这样的服务肯定会使乔做出负面的评价.因此选项A和选项B部不对。此外，这个故亊是为了指出滥用别人的个人资料会惹人讨厌，因此可推断乔对餐厅服务员的做法会感到生气。选项D虽然也是反面的评价，但是这个选项可能表明乔不介意自己的资料被盗用，只是觉得餐厅服务员使用的时候不够灵活。这与文章的主题不符。

2.[C] 推理判断题。本题考查例子与主题之间的关系。答题的依据是第1段最后两句，文章指出餐馆跟因特网一样，它们都收集用户的信息。选项A和B都只渗及表面，选項D则不如选项C确切、具体。

3.[B] 事实细节题。选择依据是第2段第3句及第4句。选项B是对这两句话的归纳。选項A谈的是可食用的甜饼，而不是本文叙述的用于收集用户信息的一种软件。选項C是对第2段第3、4句的歪曲理解。文章明确提出了cookie不是最新的发明，选項D不正确。

4.[D] 事实细节题。本句考查复杂句的理解，并涉及两个事物的对比。第2段介绍Alexa时，指明它does even more，接着用while连接一个让步状语从句，其主句是关于Alexa的信息，据此可以判断选项D正确。选项 A和B与原文不符，容易排除。选項C指出Alexa能收集到所有必要的资料，这是对其作用的夸大，实际上，根据倒数第3句，它收集的只是所有网上活动的资料。

5.[A] 观点态度题。判断依据是文中作者所使用的一些词句，如：usually without your knowledge, sound scary及最后一句。这些显示了作者对cookie和Alexa持反对、批评的态度。
