     I am a senior high school student. To my opinion, the classroom is a place for students to gain
 knowledges. So quietness is badly need for us to learn in the classroom. But recently some students 
has brought their mobile phones to the classroom and we often hear of the ring of mobile phones. 
Some of them even wasted precious time in class type short messages on the mobile phones. To
 keep the classroom quietly and make us focus more on our studies, I suggest that mobile phones
 be used in the classroom. At least, they shouldn't be used where we are having a class.
