Example 3: We live on the earth, and we are children of our Mother Nature. Our Mother selflessly offers so many things to us to live a better life. But we just want more and more from her,sometimes we even adopt extreme methods to harm our Mother, For instance, we cut down trees and exploit resources time and time again without recycling. At the same time, we leave useless things to the earth,which usually will pollute the environment severely. We are those selfish ones and think little of our Mother.

But when our Mother falls ill,can we live a good life? The answer is obvious— No! So, don't just sit back and leave the problems to the experts or the governments any more. As citizens of the Earth, we all have the responsibility and ability to preserve and sustain the environment we have. Only when we realize the importance of protecting our Earth, will the problems be solved in a more sensible（明智的，通情达理的）manner.
