提示词语：more and more, after a lot of convenience （方便） send short messages some troubles
Today, more and more middle school students have their own mobile phones. As a student, I think it”s good to have a mobile phone, because mobile phones can offer a lot of convenience. And students can send short messages to their parents when they are in trouble or not at home.
In fact, if students use mobile phones in right ways, mobile phones will help us, such as we can use mobile phones to look up new words. But it can also bring some trouble. For example, many students use their mobiles to listen to music in class. They don”t listen to the teachers carefully. And many students send messages in class.
In my opinion, it”s not right to use mobile phones in school. We should try our best to use mobile phones in right ways.
