Dear Tom, I would like to give my opinions about being on the Internet.More and more middle school students are starting using the Internet, through which they can get a great deal of the latest information.They can enjoy leons given by the teachers of net-schools at home.And it is easy and convenient to keep in touch with friends by sending and receiving e-mails.
On the other hand, some students have spent too much time chatting and playing games on the net.And there is still something harmful to the students.
At last, I suggest that students should be good at using the Internet for their studies and not be on line for long.
Best wishes, Lihua
