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."

| Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
