Protecting the Environment
Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man's existence.
We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.
As can be seen from the charts more and more people own mobile phones in China now. At the end of 2002, there were 20 million mobile phone users. By the year 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 Intemet.
However, it may also bring us some trouble. For example, if someone calls you by mistake, you will have to pay for this kind of unnecessary calls. And the radiation from the phone may do harm to our health, In spite of this, the number of people having mobile phones is still increasing steadily.
