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 the 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 not want them to have.
Are you aware that almost every time you access a website you get a "cookie"? Unfortunately, it’s not the Mrs. Field’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 this information 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.
What can be learned about "Alexa" from the second paragraph?
选项
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
D
解析
事实细节题。本题考查复杂句的理解,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。选项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。
