     A little mouse (老鼠) thinks he is the tallest and strongest animal in the world. His

mother says to him, "Don't say you are the strongest in front of an elephant. He

doesn't like that."

     The little mouse doesn't listen to his mother. He goes out to look for an elephant,

but he doesn't know what it looks like. He meets an ant first. He asks her, "Are you an

elephant?" "No, I am not." says the ant.

     Then the little mouse meets a hare (野兔) . He asks her, "Are you an elephant? You

are bigger than me." "No, I am not. An elephant is much bigger." says the hare. The little

mouse goes on.

     Suddenly he sees four big trees. "Aha, let me climb up one of the trees. Then I can see

where the elephant is." says the little mouse. Then he begins to climb one tree.

     "Get down! Get down!" someone shouts to him. "I'm the elephant. Go and climb that

tall tree nearby. Then you can see me."

     "Now I see. The elephant is the tallest and strongest animal in the world." says the little

mouse at last.
