Dear sir
I'm a middle school student. I have something to talk with you. In my school, many students have mobile phones（手机）.They think it's cool to have a mobile phone. Really the phones come in fun colours and let students talk with their parents and friends at any time. But I don't think it's good to send messages（短信）.It takes them a lot of time to do that. Some students always hope to buy the latest mobile phones and this will waste（浪费）their parents' money. And my father tells me that most mobile phones can cause health problems. Could you do something to stop it?
Yours
Mary
