【答案解析】[听力原文] Students today learn how to use computers as early as age five or six. They are also spending more time online, surfing the web, e-mailing, twittering, playing games, using Facebook, etc. Rumor has it that some even use the Internet to research term papers. The question I'd like to consider is, are people spending too much time on their computers? Some doctors believe people can misuse the Internet, the same way people drink too much or gamble too much. They call this problem Internet Addiction Disorder, or IAD for short. The doctors have identified several signs of Internet Addiction Disorder. The first sign is that a person wants more and more time on the Interact. One hour is not enough; it's got to be two or three. The second sign relates to what happens to people if they cannot get on the Internet. They might, urn, dream about the Internet. During these dreams their bodies might tremble, and their fingers might move as if they were typing. The third sign is that they need to use the Internet to stop these things from happening to their bodies. In the same way that a few drinks will steady an alcoholic, being on the Internet actually improves the way their bodies feel. Fourth, people with IAD use the Internet more often and stay online longer than they intended. For example, they might go online to check e-mail, but three or four hours later, they are still there, chatting or surfing the web, or whatever. Fifth, people spend a large amount of time doing things related to the Internet. They might read books about the Internet, for instance, or download new Interact programs, or attend Internet-related conferences. The sixth sign of IAD is that people substitute online time for social activities. Frankly, they prefer communicating electronically rather than face-to-face. The seventh and last sign is that Internet use becomes more important than almost anything else—showering, schoolwork, losing a job, and feeding children. People with IAD will also lie about how much time they are spending online, and they will keep using the Internet even if they are punished for it.
