Mrs. Zhou: The chemical factory produced terrible gas before, and the bad air made my chest hurt. What was worse, the factory made too much noise and I couldn’t sleep well at night.
Kangkang: How terrible for you!
Mrs. Zhou: Yes, it was really awful. I was always in a bad mood because I couldn’t bear the environment here. Luckily, the government has solved the problem. By the way, have you noticed there are more fish in the river
Kangkang: Yes, I have. The river is cleaner and clearer. The environment has become good. I think I should write to the newspaper to show my thanks.
