　　Mary, a young woman, had a little white sheep．She loved it very much．In the daytime she tied it to a tree to let it eat grass in the fields and in the evening she went to take it back home．

　　One evening she found someone had cut the rope(绳子)and the sheep was no longer in the fields．When her husband came back from work, she told him what had happened．At once her husband started to look for the sheep．He went around the small village, but the sheep couldn't be found．The next day Mary's husband heard that one of his neighbours(街坊), Aleco, had bought a sheep．“Perhaps Aleco has stolen(偷)our sheep”, he said to himself．But when he got to Aleco's house, he found he had made a mistake．In front of Aleco's house there was a black sheep．At that time it started to rain．He had to stay in Aleoo's house when he came outside after the rain stopped．He was surprised to find that the white sheep was standing before him．Aieoo had dyed(染)its wool black．Now it had been washed clean by the rain．
