A little sheep went out with other sheep one day.She found some nice  in the field, so she moved farther and farther away from the others. She was enjoying  .  so much that she did not know a wolf was coming to her. The wolf quickly caught her and she said, "Please, please don't eat me now. If you wait a few minutes, I will taste much  ." The wolf thought that was a good idea,   he sat down and waited. After a few minutes, the sheep said, "If you can let me dance, the grass will be digested （消化）faster." The wolf agreed again. When the sheep was  ,she had an idea. She said, "Please take the bell. If you make it ring as hard as you can, I will be able to dance even faster."The wolf rang it as hard as the sheep said. A man heard the bell ring and looked for the shiip with his four dogs quickly.  ,the sheep was saved.
