手机该不该在一些地方禁止？

I strongly agree with the opinion that the use of a mobile phone should be forbidden in
some places, such as library and airplanes. The most common reason for people going
to a library is to find a silent environment to read their favorite books without
interruption. But if you receive a phone call in the library or just send out messages, the
mobile phone will ring. Though people have personal right to use their mobile phone,
the others are not supposed to be involved in the unnecessary disturbance. And I do not
think it is very polite unless you can turn down the volume. Another place is airplane. As
we all know that it is very dangerous to have a phone call in airplane. It may causes
interference between the signals. Therefore mobile phone should be forbidden in
airplanes unless there is a new technique can avoid it.
