along with rapid growth of tecnology ,cellphone has become more and more important .
we can use cellphone everywhere.we can communicat with each other by cellphone.
from my point of view,we can not leave cellphone .some day it will be more and more
popular and convient .you need not talk with a friend face to face.everyone all have a cellphone and it will slove a lot of trouble.you can make sure Sb is in safe or trouble.you can get help bu cellphone.we can not leave it and it will be more and more important.
