Dear Editor,

Recently our school has set up a rule that no student allowed to take their mobiles into class, which has aroused a lot of discussions among we students.

Many of the students feel strong against the rule, arguing that the mobile had become a necessary part of our life. They also consider that a must for us to get relaxing from our busy studies.

When it comes to me, like some other student I hold a different opinion. While a mobile phone can help us get some relief, with it we can be more devoted to our studies, but spare more time to communicate with those around us. Therefore, I believe in this school rule is beneficial to every student.

Yours,
