My home town is in the center of Xuzhou which was a quiet and beautiful place. In the past, there were many animals. They were lovely and nice. The air was fresh and there were many birds fly in the sky.

　　Over the past years, it has changed a lot. At the present, it becomes a modern town and develops a lot. Now, the people in Xuzhou are richer than before, so most of people go to work by bus or by underground. Sometimes, they also drive their private cars to work. Many people sell out their old houses and move into new flats.

　　In some ways, the development has brought some good things, but it has also causes much environment pollution. I think we should take action to reduce the pollution.
