My view on internet
When people invented computers,then the internet appeared.Surfing on internet is convenient now .
People think this is an important invention.But I think the internet is bad for some students.
They don’t study hard at school .They paly computer games all night.Some of them don’t go to school.They play computer games all day long.We can’t say the internet is very bad for us.It is useful.But there is something bad ,too.
