Mobile phones should be banned at school
Everybody says that mobile phones should be banned at school because they usually interrupt the class. However, I think that mobile phones are necessary because it is possible you need them when there is an emergency.
On the one hand there are some arguments to ban mobile phones at school. They annoy a lot if they ring in class. Students sometimes pay more attention to the mobiles than to the teacher. This is really the reason that teachers give, but students nowadays don’t admit any reason because they want their mobile phones to listen to music at the end of the class.
On the other hand if teenagers can’t use the mobile phone they will be very unhappy, bored and it may be necessary for an emergency.
All in all, I believe that mobile phones are needed. However, I admit they can makethe class difficult if they are on.
