I think students should take moblie phone to school。We need mobile phone everday。We even can not image the life without a phone。
During school time we are busy。For some free time in school,we may wanna talk with our parents。What's more, take a mobile phone to shool can keep touch with our families so that they are not too much worried about us。
We need the sense of security,so we need a mobile phone in case some thing happened like nearby fired so that we can call the fire brigade。
But we should not open our phones all the time。In class,we should turn down our mobile phone and focus on studies。Some people may say that take a mobile phone to school can divert students' attention from studies,but this is not the comprehensive statement,we can avoid this and we can make full use of mobile phone even in studies。
