No, I do not. I think high school students should
bring their smartphones. I have a few reasons. First,
it is convenience for them to use their phones when
they need sending messages for their parents.
When their children come home late, they can chat
on each smartphones. Second, by using
smartphone, it will be able to make students'
education more easily. For example, they can use
their smartphone when they want to know mean of
English words in classes. For these reasons, I hope
those school will be change the school regulation.
