 阅读理解。                                                                              

     I began to send e-mails 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, and about half of these children use it every day.  They visit chat (聊天) rooms and

 send e-mails.  They go to websites to get information for their homework.

     "Kids are now living in a virtual (虚拟的) world," says Greenfield, an expert at the University of

 California, "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 difficult to answer the question because the Internet involves (涉及) so many things," says Justine,

  who is from Northwestern University.  "They include online computer games, news, messages and even

  e-mails to your grandmother. " So, more and more people believe that the online world can be helpful in

  some ways but 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. "
