I began to send my first e-mail when I was 17. I discovered Google 5 years later. Now, I use the Internet all the time. Internet has become so popular that 90 percent of 12-to-17-year-olds in the United States use the Internet, according to one recent survey, and about half of those kids use it every day. They visit chat rooms and send e-mails. They go to Websites to get information for homework.

“Kids are now living in a virtual(虚拟的) world,” says Greenfield, “As the Internet is becoming more and more important for our life, we should worry about one question: Is the Internet good or bad for kids?”

“It’s X to answer the question because the Internet involves so many things,” says Justine, a media expert at Northwestern University. “They include networked computer games, news about politics, instant messaging and e-mails to your grandmother. ” So, more and more studies shows that the online world can be helpful in some ways and dangerous in others.

“Although it’s not easy to tell whether it’s good or bad,” says Justine, “the Internet, at least, is very useful and can be used widely by everyone in the world. ”
