Li Mei puts her hand into the pocket, takes out her mobile phone and presses the talk key. “Hi, mum! I’m on the bus. I should be home in about 10 minutes.” Li Mei is one of many Chinese teenagers who live life “on the go” and use mobile phones.

Mobile phones make it possible for us to talk to anyone from anywhere. Modern mobile phones are more than just phones-they can be used as cameras and radios, and to surf the Internet. Many mobile phones have features such as playing games and listening to the music.

Mobile phones have changed our behavior(行为) and how we communicate. They are used everywhere－sometimes where they shouldn’t. One headmaster says that phones are not allowed in the classroom. “If a phone starts ringing in the classroom, teachers and other students cannot work well.” “I don’t dare to use the phone in school, because they will take it away from me,” says Hill, a student in London. Hill got his phone for his birthday, but his parents don’t let him use it in school. Some parents worry about that their children will spend too much time and money on phone calls.

Why are mobile phones so popular, especially among teenagers? The answer seems to be that we have a need to stay in touch with friends and family no matter where we are or what we are doing. Having a mobile phone also makes us feel safer, since we can for help when we are in danger. Of course, to many teenagers it is not only a useful thing but also a way to have fun and be cool.
