A crow（乌鸦）is sitting in a big tree. She has a big piece of meat in her mouth.“My babies will have a nice breakfast,”she thinks. An old fox is looking for his breakfast. He sees the crow and the meat.“How can I get that piece of meat?”he thinks.
   “Good morning, Mrs. Crow.”says the fox,“How are you?”But the crow doesn't say a word. “You have very nice babies, Mrs. Crow.”says the fox,“How are they? May I see them ?”Still the crow doesn't say a word.
   “You are very beautiful, Mrs. Crow, and you have a beautiful voice（嗓子）,too.”says the fox,“Would you please sing a song for me? ”Mrs. Crow thinks“How nice Mr. Fox is! I must sing him a song.”So she opens her mouth and begins to sing. At that time, the meat drops down（掉下）from her mouth.
