必背作文
我们生活的地球正面临着巨大的环境压力，如空气污染、水污染、固体废弃物污染、动物濒临灭绝等问题。因此，将环保行动渗透到日常生活是我们每个人的责任。请你选择其中的一个问题，自拟题目，写一篇英语短文，谈谈引起此问题的原因，并讨论公众如何从点滴做起来解决问题，使我们的世界变得更美好。
Air Pollution Problem
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 burn 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 to stop giving out black smoke into air. Next, we’d better 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 take the bus. (高分句型) Besides, I think smokers shouldn’t smoke in public. What’s more, it‘s a good idea to plant more trees and flowers．(高分句型) Planting trees not only makes air cleaner, but also makes our environment more beautiful．(高分句型)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 problem. I'm sure that our actions can make a difference and lead to a better future.
