     One day a tiger catches (抓住) a fox (狐狸) in the forest. Before the tiger could eat him up, the fox cries

out, "You can't eat me. Don't you know that I'm king (王) of the forest. If you eat me up, all the other animals

in the forest will be angry with you."The tiger doesn't believe him."How can such a small animal be king of the

forest?" He asks himself. "If you don't believe (相信) me," the fox says,"then take a walk with me in the forest.

You can see for yourself whether (是否) they are afraid of me."The tiger thinks it is a good idea, so the fox

walks in front and the tiger goes behind. When the other animals see the tiger coming, they run away as fast

as they could.
