A mouse called Mike and a frog called Jim were friends.Every morning the frog would jump out of the water to visit his friend. The mouse lived in a hole beside a tree.

Mike was happy to see his friend visiting him. But he didn’t realize that the friend was slowly turning into an enemy（敵人）. Jim was angry with the mouse because he never visited his house in the water.

One day, Jim felt he couldn’t stand any more. When it was time for him to return home, he tied（系）one end of a string around his own leg, and the other end to the mouse’s tail. Then he jumped away, with the poor mouse behind him.
