A: I like this poem very much.

B: Can you tell me something about it?

A: Of course. It describes ordinary life in a small village of Kun Ming. People there  live peacefully and get on well with each other. There is little pollution and it is very beautiful .Above all, people there  have a good time!

B: Wow, I like the village too. Environmental pollution in Beijing is so serious that we must wear a mask everyday. I can't bear it anymore!

A: Yes, we should do something for it,such as ride a bike or take a bus instead of driving your own car when we go out, use less plastic bags, and so on.

B: We should do more for our next generation.
