No a Good Idea

¿Do you know what cellphones are causing? Maybe you don't know, but they are causing a big damage to the teenagers. When they take out the cellphones in class the put more attention to the cellphone than the teacher that is explaining the class. The cellphones can help us but is not a good idea to use them while you have to do another and more important thing. If you do this you won't put attention and you won't be able to pass the exams, so please don't take out your cellphones and have good grades.

Too Important

Cellphones are very important for teenagers now a days. The cellphones have a lot of applications that teenagers use like games, calculator, messenger and more... But I think that teenagers must know  how to use these applications because when they use them in class they can be bothering the rest and they don't put attention in what they have to do. I think we have to use it in special moments not in class.
