My dear brother,
I've heard that you often take your mobile phone to your school. It's not suitable for you to do this. I write this letter to give you my opinion about taking mobile phone to school.
Nowadays it's very common for students to take mobile phones to school, but many students don't know how to use their mobile phones correctly. As a middle school student, it's not good to have too much communication with friends outside school because they are not students and some of them have many bad habits which will do harm to you. You should study wholeheartedly in school.
I hope you can learn some lesson from others' examples and do not take your mobile phone to school anymore.
Your elder brother
Li Dong是有關(guān)于一個雜志社編輯看到當事人的來信（關(guān)于學校規(guī)定不能帶手機使他煩惱），因而給他回信。在信中發(fā)表自己的看法和建議！再麻煩一下，拜托啊~~~~Now as the society is developed,many students have mobiles now.Especially in the middle school,many boys and girls take the mobiles in the class. The music often rised during the classing.This make the teachers very confused.I think all of us are very young,no need the mobile.If your parents really have many money and bought a mobile for you. Please shut off before you go into the classroom.
