Once a great lion was sleeping. A little mouse came and ran over his face. The lion awoke (醒来) and
caught the little mouse in anger, and was going to kill her. "Oh, dear kind lion!" said the little mouse. "Please
forgive me. Let me go. I shall return (回报) your kindness." "Ha, ha, ha," laughed the lion. " How can a little
thing like you help a great lion?" " Thank you very much, kind lion! I hope I shall be able to do you a good
return some day," said the little mouse.
Some day, the lion was caught in a trap. Just then the little mouse came along. At once she ran up to the
lion, and said, "You were very kind to me once. Now I'll save your life, and repay you the kindness." Soon she
gnawed the ropes of the trap with her sharp teeth, and the lion was happy to be free again. "Thank you, little
mouse!" said the lion, and he walked away.
