【正确答案】A Letter to the President
Dear President,
Thank you for reading my letter. My name is Kang Yan, and I'm a student at the college. I'd like to say something about the usage of mobile phones among college students.
Nowadays, more and more college students use mobile phones on college campus not for its convenience but for its fashion and popularity. On the other hand, using mobile phones affects the normal teaching order to some extent. In the lecture, sometimes we hear the phone ring here and there, and some of the students send short messages now and then. As a result we couldn't concentrate on our work.
People have different opinions about it. I think it's good to use the mobile phones, but the students shouldn't use it in the lecture. Finally, I hope you can pay attention to the phenomenon.
