参考作文：

Dear Editor，

Nowadays mobile phones are becoming more and more popular among the middle school students. Some students think that it is easy to use them to keep in touch with parents and classmates.Also，they can be used to listen to music or take photos. But others think that we don't need to talk with parents and classmates with mobile phones，because we meet them every day. And mobile phones may influence our study.

In my opinion，it's not wrong to follow the fashion，but the most important thing is how to use the mobile phone in a right way.
