英语作文假如你是李华,对电子产品危害中学生身体健康给

Dear Editor,
I am a student in a senior high school. I am writing to share my worries about my classmates.
With the development of IT industry in recent years, many of my classmates have 3G mobile phones, iPods or MP4. Although the modern equipment can inform us of the latest news, make us relaxed and keep in touch with our friends, they have negative effects on us. I have noticed that some of them play computer games, watch movies or chat online after class, even in class. This has caused them to lose their interest in their lessons and want to play with their 3G mobile phones, iPods or MP4. So I am worried about them.
I hope 3G mobile phones, iPods or MP4 should be banned at school. Do you agree with me?
I am looking forward to your early supply.
Yours,
Li Hua
