A popular social behavior
There is a popular social behavior now.It is that some students make friends on line.
It has some advantages.On the one hand,the friends you made are from many different countries.They can make you learn from them and know about much interesting knowledge and watch the world well.On the other hand,it can also make people feel relaxed and fun.So Children will have fun learning it.
And it also has some disadvantages.Children cannot control themselves well.So children will waste time to surf the Internet.And they will be worse and worse.
I think if children could control themselves,making friends on line is a good behaviour.If not,parents should help to control their children.
