The students are having their chemistry(化学)class. Miss Li is telling the children what water is like. After that, she asks her students some questions, and one of them is, “Boys and girls! What is water? Can you tell me?” She waits for a few minutes, but no one answers her. Then Miss Li asks again. “Why don’t you answer my question? I tell you what water is like , right?” Then a boy puts up his hand and says, “Miss Li, you tell us that water has no color and no smell(味道). But I think that water is something that is black when I wash my hand in it.” All the students begin to laugh(笑). Miss Li laughs too. Then another boy puts up his hand, Miss Li says “What do you think, Wang Bing?” The boy says:” Miss Li, where can we find water that has no color and no smell?” “Why do you say so?” Miss Li asks. “The water in the river behind my house is always black and it has a bad smell.” Answers the boy. And most of the children think he is right. “I am sorry to hear that, children.” says the teacher. “Our water is getting dirtier(脏). That is a problem. All of us must try our best (尽力) to make it clean again.” 小题1:Which of the following is right?
