Nowadays,with alteration of the electronic devices .Phone become a more and more important character in society,Especially for teenagers.Just like every have two sides.Phone also has the bad sides like bad information
Some people think that the teenagers is not have enough self control to use the phone in the right way.As everyone knows phone is an important part of internet as a tool.A large number of unhealthy websites and will harm for students' mental health.It bring bully and abuse to teenagers especially in school.In the other way, phones always make teenagers wander on class or other things.Thirdly ,Phones cut out the ways of communication face to face.Some teenagers prefer using phones to talking with people by his side.
On the contrary,other people think that the phone is important for communication.
It aloud them talk to friends and family anytime and anywhere. Its very convenient, especially in place other than their hometowm or call everything is OK to their parents.Secondly,the phones are commonly used as a the tool to search for information which they interested or improve themself .
In my opinion,phone just like a double-sides sword.If use it in the right way , it can improve you.However,if you addiction to it.It is harm to you.So,use it in the control is good for everyone.
