二、篇章训练
One possible version:
Air Pollution
At present, more and more people pay attention to the environment around us. As we know, the nice environment is good for our life and health. However, there are some kinds of pollution problems in our life, like air pollution，noise pollution, water pollution and waste pollution. Now I want to talk about the air pollution.
The air is badly polluted. Here are some reasons. First, the factories that bum coal pollute the air with a lot of black smoke. Second, more and more people take cars to school or work. Third, some people smoke.
There are some methods to solve the problem. First of all, we should ask the factories tostop giving out black smoke into air. Next, we’d bett er ride bikes or walk instead of driving to school. The advantages of bike riding or walking are that it’s good for health and it doesn’t cost anything. If it’s far,
I suggest we could take the bus. Besides, I think smokers shouldn’t smoke in public. What’s more, it’s
a good idea to plant more trees and flowers. Planting trees not only makes air cleaner, but also makes our environment more beautiful. Finally, we need to recycle books and paper and stop using paper napkins. That can help us cut down fewer and fewer trees.
I think everyone should play a part in solving the air pollution. I’m sure that our actions can make a difference and lead to a better future.。
