John lived with her mother when he was young. He didn’t know who his father was. The woman did some washing for the rich and could buy only some bread for her son. So the boy was short and thin.

  One cold morning there was much snow in the streets. A car knocked the woman down and the policemen took her to the hospital. She didn’t tell John that his father deserted(遗弃) her before he was born until she died. She left her son the name and address of his father.

  John found his father, Mr. Brown, in another city. He was one of the richest shopkeepers and he had to receive his son. From then on the boy lived a rich life. He ate all kinds of delicious food and wore beautiful clothes. But he didn’t go to school and could not read or write.

  Once his father took him to a party. He saw a newspaper lying on the floor and picked it up while others were talking about a film. He had a look at it and found a car’s wheels(轮子) were upward(向上).He called out,“ Oh, dear! An accident happened!”

Air is a colorless, tasteless and invisible（看不见的）gas that is around us. An “empty” drinking glass and an “empty” room, in fact, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.

Air, as a gas, has no definite shape, but because it is matter, it takes up space and it has weight. It is easy to prove that air is something that takes up space. Stuff a piece of dry cloth（布）into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside down glass, holding straight up and down, into a jar of water till the glass is completely covered. When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.
