A. use the Internet,and about half of these kids use it every day. They visit chat rooms and send emails. 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 (专家) at the University (大学) 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 X to answer the question because the Internet involves (涉及) so many things. " says Justine,an expert from Northwestern University (西北大学) .They include (包含) online computer games,news,messages and even emails to your grandmother".
