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 answered. 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 color and no smell
(气味). But where to find such kind of water (这种水)? Then water in the river behind my house is
always black and it has a bad smell." Most often children agreed (同意) with him.
