Natural enemies can become best

　　Right in the middle of Japan, high in the mountain, an old man lived in his little house. He found in one corner of the room an old iron1 kettle2. He decided3 to use it to boil water. To his surprise, the kettle became a strange creature when it was on the fire. And then it changed back into a kettle again. The old man decided to sell it. So a merchant came and went away with the kettle.

　　At night, the merchant was awakened4 by a big noise. The kettle became a strange creature again and was running about（乱跑） in his room. But early next morning found the kettle still quietly lying in the corner. One of his neighbors, after hearing what he had seen in the night, advised him to travel in the country to display it.

　　Now the kettle could be asked to change and perform by the merchant. The performances drew（牵引，描绘） big audiences, and the merchant earned a lot of money. But he was an honest man. Though he was rich now, he thought that he owed5 some of his wealth to the man from whom he had bought the kettle.

　　One morning, he put a hundred gold pieces into the kettle and, hanging it on his arm, he returned to the old man who had sold it to him. The old man thanked the merchant，saying that few people would have been so honest.

　　The kettle brought them both luck. Everything went well with them till they died.
