The students were having their chemistry (化学) class. Miss Li was telling the children what water was like. After that, she asked her students, "What's water?" No one spoke for a few minutes. Miss Li asked again, "Why don't you answer my question? Didn't I tell you what water is like?"

Just then a boy put up his hand and said, "Miss Li, you told us that water has no colour and no smell. But where to find such kind of water? The water in the river behind my house is always black and it has a bad smell." Most of the children agreed with him.

"I'm sorry, children." said the teacher, "Our water is getting dirtier and dirtier. That's a problem."
