The students were having their chemistry (化学)class. Miss Li was telling the children what water is 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 abad smell.” Most of the children agreed with him.

“I'm sorry, children,” said the teacher, “our water is getting dirtier. That's a problem.”

    It was cold yesterday. Tom didn't go out. He did housework. Sam went to play football. And he had a cold. He fell ill today. He's got a fever. Lili phoned him. She will come to see Sam. Sam's mother cooked lunch. They had noodles and eggs for lunch. Sam drank lots of hot water. It's good for him.

    The weather is fine. Amy and John are in the park. It is a big park. They can see many people there. Some boys are playing football on the grass. Some girls are singing and dancing. An old man is reading a newspaper under a big tree. A young woman and her little son are playing with a toy bus. They are very happy.

    Mr. White has a daughter and a son. They live in the countryside. It is near a mountain. They were very poor before. They had little money. They bought some seeds. They planted rice, carrots and beans in the field. They worked very hard，and they were very happy.

    One day, some big birds came. They ate the rice, the beans and the carrots. Mr. White was very angry. He got the birds out of his field, and then he put some scarecrows（稻草人）in the field. There are no birds now. In autumn, Mr. White has got a lot of beans, carrots and rice. The Whites are happy again. They are not poor now.
