(限时：每篇8分钟)
(一)
Thank you for read my letter. My name is Li Ming, and I'm a student at college. I'd like to say anything about the usage of mobile phone among college students.
Nowadays, college students use mobile phone not only for its convenience but also for its fashion and popularity. Besides, using mobile phone affect the normal teaching order to some extent. In class, sometimes we hear the phone to ring here and there, and some of the students sent short messages now and then. As the result, we can't concentrate our work.
People have different opinion about it. I think it's good to use mobile phone, but college students shouldn't use them in class. Finally, I hope y ou can pay attention to the phenomenon.
