a mobile phone can lead to us a comfortable life,we can use it to send short massages,to exchange between good friends or even to play some games by using it,it gives us much more interests and helps us a lot.every coin has two sides.what we should think of its disadvantage worthing considering.though it can gives us a happy time,it also makes us spending times on it playing games.we may cost much on it.we should watch it right.as a citizen,i use;as a student,i pay attentions to.only to use it right can we have a real happy life!
