问题 资料:Imagine you went to a restaurant with your girlfriend, 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 last time. Would you like to join her for dinner again?” Then you find out that your burger has been cooked and placed 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 recipe. 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 yourself, including where you visit, how long you stay there, and how frequently you return to certain pages.While this may sound scary enough, cookies aren’t even the latest in technology. A new system call I-librarian Alexa——named after 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 activities, such as which site you visit next, how long you stay there, whether you click on advertisements, 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”?A.Alexa is named after an ancient hero in Egypt.B.Alexa is installed in libraries.C.Alexa can provide all the necessary information about history.D.Alexa can provide more data to marketers than a cookie.

【主题句】第4自然段A new system called I-librarian Alexa—named after 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 activities, such as which website you visit next,how long you stay there,whether you click advertisements,etc.All this information is available to marketers, who use it to market more effectively to you.一个名为“I-libra.Alexa”的新系统,以埃及亚历山大公元前3世纪的传奇图书馆命名,它做的更多。cookies跟踪你在一个网站上做什么,Alexa收集所有网络活动的数据,比如你接下来访问哪个网站,你在那里停留多久,你是否点击广告等。所有这些信息对营销人员都是可用的,他们用它来更有效地向你推销。
