交通
The traffic is very heavy and buby in China's big cities ,especially in Beijing .More and more Chinese peole spend a lot of money on thrir private cars. So we have got traffic jams every day .Because people are usually busy with their work and life, I think we'd better have a good public. In this way, we can reduce the traffic jams and the traffic accidents.

污染
Pollution is a serious problem in the world. More and more people show great concern to it. Due to so many cars and chemical factories, we cannot avoid having the problem of pollution. And pollution can do great harm to our human health and environment. I think we should begin reducing the pollution with ourselves. Everybody should do something with the problem of pollution.
