     The Internet brings us many advantages.

      With the Internet, people can send and receive e-mails. On the Internet, people can skim over news. Using

the Telnet, the user anywhere on the Internet can log into any other machine on which he has an account. It is

possible to use the FIP program to copy files from one machine on the Internet to another.

      But the Internet also brings us troubles.

     Internet use seems to cause a fall in psychological (心理的) health, according to research at Camegie

Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often, the two-year study showed. And it wasn't that people who

were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the

bad feelings.

     Researchers are puzzled over the results, which were completely opposite to what they had expected. They

expected that the Net would prove socially healthier than television, since the Net allows users to choose their

information and to communicate with others.

     The fact that Internet use reduces time used for family and friends may be the reason for the drop in health,

researchers said. Faceless, bodiless"virtual" (虚拟的) communication may be less psychologically satisfying

than actual conversations, and the relationships formed through it may not be so deep. Another possibility is

that exposure to the wider world through the Net makes users less satisfied with their lives.

     "But it's important to remember this is not about the technology; it's about how it is used," said one of the

researchers. "It really points to the need for considering social factors (因素) when you design new inventions."
