Unit 3 Alienation and the InternetKey to ExercisesText ComprehensionI. B.Ⅱ. TFFTTⅢ.1. As the author sees it, the Internet is most likely to make our global village a better place to live in. It provides a miraculous forum for the globalization of ideas, which contributes to the realization of human potential. Furthermore, it is a powerful tool for the acquisition and application of knowledge. The benefits of the Internet, however, may be darkened by its negative consequences. It may deprive its user of his time for necessary interaction with other society members so that the whole world may be further fragmented. In addition, there is a reasonable likelihood that the Internet presents too much information, which gives its user a skewed sense of reality by making him a cognitively overloaded man.2. His friend was addicted to the Internet. He would spend even over twenty-four hours non-stop on the Internet so that he had to force himself to go off line. As he spent so much time in cyberspace, his sense of reality might have been crooked. Moreover, without any face-.to-face verbal communication with other people, he felt lonely and depressed.3. The alienation of society members had begun long before the Internet started to be used worldwide. After World War 1I when the soldiers returned from the battlefields, they devoted themselves to "progress". What did to achieve their goal was to manufacture large quantities of cars and make them available to most people. With the car people could travel around more easily, but at the expense of their reunion with their extended families and communications with their neighbors. Thus, it is apparent that it was the car ownership that alienated people before the Internet. In the information age, however, people are alienated not so much by cars as by the Interact. Interact addicts are far from rare. As illustrated by the example of the author's nephew, it seems to be an irreversible trend that more and more people, old and young, are becoming addicted to the Internet. They will spend many hours non-stop in cyberspace rather than with their families or friends. For lack of communications, they are becoming strangers to other people. Therefore, there is a good reason to believe that the society is being further alienated by the Internet.4. The "cruel irony" means that the Internet provides the user with a convenient means of communicating and making friends with people far apart on the one hand, but on the other, it estranges the user from the people around him by canceling his availability for the face-to-face communications even with his families and close friends and for involvement in the community activities.5. The potential of the Internet as a powerful tool for globalizing ideas and for acquiring and applying knowledge can only be realized when its user strikes a balance between the reality and the Internet. Although the Internet makes it possible for its users to debate, shop, travel and have romance in cyberspace without leaving home, the overuse of this tool probably results in a distorted sense of reality. The only way to avoid being penalized by the Interact is make moderateuse of this tool without losing one's sense of place in the world.Ⅳ.1. As the Internet can be reached and used with relatively few restrictions, it plays a role in connecting people globally, which is comparable to traveling through international waterways.2. A lot of people talk about the "new information age", but not so many people are acquainted with the idea that the Internet separates people from each other and fragments society further as a result.3.
