A farmer had four lambs(羊羔). One was black, and the other three were white. The black lamb was friendly to the others. But the white lambs often laughed at him. They thought he was ugly. The farmer did not like him either. He gave bad food to the black lamb.
One winter morning, the four lambs went out to eat grass. They went far away from home. In the afternoon, it began to snow. It was such a heavy snow that the ground was all white soon. They couldn't find their way home.
When the farmer found that the lambs were not at home, he went out to look for them. There was snow everywhere. It was difficult for him to find his lambs. Suddenly, he saw something black. He went to it. Oh, it was his black lamb! And the white lambs were there too. The farmer was very excited. He said happily, "Thanks to(多亏) the black lamb, I can find you!"
