Dear Tom，
Your letter reached me yesterday.I'm so these are my somethoughts.
Advantage of the cellphone is we can in touch with eath otherconvinentely,however,there are some disadvantages about example,if you goto school with the cellphone ,it would make bad influence on 'smore,the cellphone is harmful to your health,your eyes will be worse andworse,your body will be weaker and weaker and so ,I don't think it'sterrible for you to use the cellphone at the school.
These are my thoughts,I hope they will be useful for you.
