One morning, a little mouse went out to find something to eat. He was careless and met a fierce（凶猛的） lion. The lion caught the mouse. The lion wanted to eat him.
“Please let me go ,Mr. Lion.” said the mouse.“One day, I will help you.”
The lion laughed, “How could a little mouse help a big lion?”“Well,” he said, “I will let you go. But you must walk more carefully.”
The mouse was very thankful. “Thank you, Mr. Lion. You are very kind. I will repay（报答） you one day,”the little mouse said.
The next week, the mouse was looking for something to eat again. He saw the lion under a tree. But the lion was tied tightly（紧系着） in a strong rope. He could not get out.
“I will help you,”said the mouse. His teeth were sharp. Then he bit one rope, and then another. Soon the lion was free. He was very happy.“Thank you, Mr. Mouse,”he said. Later, they became good friends.
