As the development of the society, people is getting richer and richer. And every student has their own cellphone. The cellphone make our life more convenient, but it also has both sides. The supporter thinks that it can make students get in touch with their family and surf the internet easily .The objector thinks that it will disturb the class principle if students use it in class, and make bad effects . In addition , the call bill for a student is a waste.
As far as i can see, the student has a cellphone is convenient ,but the cellphone can't be used in the class. We use cellphone in class can have a bad effect on our study, and also make a bad impression on our teacher. So i suggest that those students who cannot control themselves should not take a cellphone to class.
