Sample6 ： Pollution around us(保护环境)
　　In recent years our life is becoming better and better.
　　But our environment is becoming worse and worse. It’s very bad for our life. Now many people have air-conditioners and cars, they produce (give off ) waste gas. More and more trees are being cut down. There are so much sand on the earth (leaving only sand ) . We often see factories pour waste into rivers or lakes. Water in the river is quite dirty. We haven’t  enough clean water to drink in cities. Now we are in danger. It’s very necessary and important to protect the environment well.
　　I think if everyone tries his best to protect the environment, the world will become much more beautiful , and our life will be better and better .
