Bringing cell phones to school is not good. I think that they may bring some trouble
in school. My reasons are as follows.
In the first place, students may not concentrate on their studies in class. If his cell
phone rings, it may cause him nervous and make a bad surrounding for studying. In the
second place, if someone brings an expensive cell phone to school, it may be stolen.
Therefore, I oppose to bringing cell phones to school, even if they need to call her or
his parents to help them bring something they forgot to take to school. If necessary, they
can use the public phones in school or turn to their teachers for help.
