Have you ever been ill? When you are ill，you must be unhappy because your body becomes hot，and there are pains all over your body. You don't want to work，you stay in bed，feeling very sad.

　　What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with your eyes，but you can see them with a microscope. They are very small and there could be hundreds of them on a very small thing.

　　Germs are always found in dirty water. When we look at dirty water under the microscope，we shall see them in it. So your father and mother will not let you drink dirty water.

Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.

　　Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.

　　Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket.
