editor,
I’m writing to tell you something about how we students use the Internet．As we all know, the Internet is playing a important part in our daily life．We often read news at home and abroad and learning foreign languages by ourselves on the Internet．Sometimes we sent e-mails to our families as well as our friends．Beside, we listen music, enjoy films and play puter games on it．We can even do shopping without leaving our homes．
However, it has its disadvantages．We waste too much time playing the electronic games, that has a bad effect on our studies．What’s worse, the bad information on the Internet do great harm to them．I hope we can make the use of the Internet proper for our studies．
Yours truly
Zhang Hua
