Should studenrs take moblie phones to school?

I do not agree that the students take their mobile phone to school.
1) They will disturb their classmates and teacher when they use their mobile phone in lessons.
2) The students who take mobile phone to school, cannot pay more attention in lessons.
3)During the test or examination, they can easy to get the information from Internet or other people.
4)It is easy to happen the problem of stealing mobile phone.
5)They will play games from the mobile phone.

諗到咁多咋,希望幫到你 : )

Also,bring the mobile phones to school perhaps will shift their focus
when they are concentrate in the lesson.This is the most worse effect..

1. Play games

They will play games in their mobile phone when they are having their
lesson.

2. Ringing

Students will always forget to turn off the mobile phone, so the mobile
phone will ring during the lesson.

3. Lost

If they lost their mobile phone, it will occur a lot of problem, eg, money,
check other classmates school bag, etc.

perhap they will play the games which are in the mobile phone during the lessons.
moreover,they can take the photos of the teacher.And then they will upload them on the internet.So,we should decrease the chance of the student bringing the phone to school.
