大姐大姐,求个英语作文,题目是；给报社写一份信,反应学生在教室拿手机,建议不要拿手机!急 紧急

Dear sir and Miss,
I am a middle school student.thesedays,I find a problem that is more and more students using intellent phone in class.I think it is bad for us.
It is well know for us,the class is where we learn knowledge.The environment is important for us.However many students don't study but playing phone.As we know there is many games in phone,students must pay attention in games not studying.Then,they can't listen the teacher say,they can't study anything.It is dangerous.
So,I think we can't keep this phonomenon.We must find a good means to solve the problem.If you can publish a thesis about the disadvntages about mobile phone in newspaper,then many pepole could read it and know it is bad for the students who often play phone in class,It must have positive affect.Thank you very much.I'm looking forword to your letter.

好久不写英语作文了,很多好的句子都没用上,就讲究凑活看看吧,可能还有单词和语法是错的,自己再改改啥的.不知道写多少词,大概就这些,自己再填点应该就够了
