最后，附上一篇关于 环境问题——雾霾 的作文模板，大家也可以自己练练手：

Recently, fog and haze has become a imminent threat which most northerners in China are facing. While the cities of China have greeted striking speed of development with open arms, they suffer greatly from a persistent and dense haze of pollution and smog. It is high time that we took some methods to protect the environment and ourselves.

Generally speaking, there are three effective ways. First of all, the government should take into serious consideration the emergency and severity of the air pollution, and take measure to deal with it. Such as more public transportation systems should be put in use, more energy-saving resources should be utilized. What’s more, every little effort from individuals counts. The citizens should contribute to the reduction of pollution by driving less. Last but not least, try to reduce the time of outdoor activities, especially when the air quality is not good enough.

From what has been mentioned above, to protect our air, we must keep in mind that whatever we give out, we take back in the long run. So we have to drive less, pollute less and make more changes.
