Do you know how to keep fish at home?The fish need room. They must not be crowded（拥挤）. Fish need oxygen(氧气). Fish get it from water in the tank. There must be enough water for all fish in the tank. So the size of the tank is important..
In the tank many people put small plants(植物). They give oxygen to the water. Plants help in other ways, too. Fish can nibble(轻咬)on the plants. They hide in the plants and sleep, lay eggs there.
Both the plants and fish need light. You can put near a window. It will get light there. But remember: a window may let cold air in. The cold can kill(杀死) your fish. Too hot water can kill your fish, too.
The fish need food and you should feed them every day. Giving them too much food is bad. It will make the water dirty. However, the fish should get just enough food. They should finish the food in 10 minutes. No extra(多余) is left. When this happens, the amount(数量)of food is right.

Long, long ago there was a very foolish thief. Do you know what he did one day? When he wanted to steal (偷) the bell on his neighbor’s door, he walked up to the door, took hold of (抓住) the bell and pulled hard. The bell made a very loud noise. The thief was afraid and went home.
Then he sat down to think, “I must do something about the noise,” he said. He thought and thought. At last he had an idea. “Ah, I’ll put some cotton in my ears. Then I won’t be able to hear the noise.” The next day he went to the door of his neighbor, and took hold of the bell. This time he pulled even harder. The bell rang loudly, but the thief did not hear anything. With another hard pull he got the bell out. Just then the neighbor came running out. “Steal my bell? I’ll teach you a lesson (教训),”the angry man shouted. And he hit the thief on the nose.
The foolish thief did not know how the neighbor found out he was stealing the bell. “Why did he come out just then?” he wondered (感到疑惑).
