Should mobile phone be used in class?,手机应该在课堂上使用吗?英语议论文150字

With the development of technology, it is common for people to used mobile phone everywhere. However, more and more students used it in their class. In my opinion, they should not use their mobile phones in class.

First of all, students will depend on their phones when they do not know the answer to their homework. Secondly, students would want to used their phones to play games in class, which will disturb other students in class. Students cannot pay attention to the teachers. Last but no at least, students will compare their phones to others, they will spend too much money on it.

As far as I am concerned, students should not use phone in class.
