Nowadays cellphones are popular in big cities in China。 It seems that they are popular at school， too。 And in some schools most of the students have cellphones with them everywhere。
One day， Teacher Wu was giving a maths lesson when the ringing of a cellphone interrupted him。 He got so angry that he shouted at the boy whose phone was still ringing。 "Don"t you see the sign that cellphones are forbidden in school How dare you use your cellphone here in the classroom " he asked the boy， pointing at the sign above the blackboard。 The boy looked as if he hadn"t realized what had happened to him。 Ee must have forgotten to turn the phone off before class。
However， the boy wasn"t able to escape from the school punishment。I think students shouldn"t use cellphones in school。 The ringing of the phone in class not only interrupts teachers， but also spoils the class。
