Mobile Phone

      As can be seen from the chart, more and more people own mobile phones in China now. At the end

of 2002, there were 20 million mobile phone users. By the years 2005, the number has reached up to 30 million. People have found mobile phones very convenient. They can get in touch with each other whenever and wherever they like. There are many different functions to meet different needs, such as sending short

messages and surfing the Internet.

   However, it may also bring us some trouble. For example, while you are enjoying a movie in a cinema,

a loud noise may suddenly interrupt you. And the radiation from the phone may do harm to our health. In my opinion, there should be mobile phone rules in public places. If you are at a lecture, you'd better turn

off your phone. When you get a call, keep the call short and speak quietly.
