练习题一
文章节选： 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。

题目： In the restaurant story, the author may most probably think the waiter or waitress was ________ 。 A. considerate B. polite C. irritating D. unsmart

答案解析： 正确答案是C。这是一道推理判断题。文章通过描述餐馆服务员根据顾客的个人信息，招呼他坐在上次约会的女友身边，并为他准备了与上次同样的食品，包括他节食忌用的汉堡，这样的服务显然会让顾客感到不舒服。因此，作者可能认为服务员的做法令人恼火。

练习题二
文章节选： 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。

题目： What can be learned about “cookie” from the second paragraph? A.It was first created by Mrs. Reid. B.It collects information on you without your knowing it C.It’s some information sent to your computer about yourself. D.It’s the latest in technology.

答案解析： 正确答案是B。这是一道事实细节题。根据第二段的描述，互联网上的cookie是一种计算机代码，由网站发送到你的电脑，通常在你不知情的情况下收集关于你互动的信息，包括你访问的地点、停留时间、返回某些页面的频率等。

练习题三
文章节选： 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 this information is available to marketers, who use it to market more effectively to you。

题目： What can be learned about "Alexa" from the second paragraph? A.Alexa is named after an ancient hero in Egypt B.Alexa is installed in libraries. C.Alexa can collect all the necessary data on you. D.Alexa can provide more data for marketers than a cookie.

答案解析： 正确答案是D。这是一道事实细节题。第二段介绍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Alexa能为营销人员提供比cookie更多的数据。
