1、An English newspaper made a survey on whether students can go to school with mobile phones.

Some students think it’s necessary to have a mobile phone. First, it is fun to chat and send short messages. Second, it’s convenient to call their parents and friends. Besides, it’s trendy.

However, others disagree. In their opinion, you will waste much time. If it rings in class, both your teachers and classmates will be bothered. What’s worse, because many students try to buy more expensive mobile phones, they add pressure to their families.

Here is some advice. Students mustn’t use mobile phones in school. They should concentrate on their studies.
