   There is an old tiger in the forest (森林). He doesn't want to look for (寻找) food now. He often lets other animals get him some food to eat.
   One day, he sees a monkey and says, “I am hungry, monkey. Go and get me something to eat.” “I can't do that now, tiger,” the monkey says, “There is another tiger over there. He does not let me get anything for you to eat. I am afraid of (害怕) him.” “What?” says the old tiger. “Take me to that tiger. I want to talk to him.”  The monkey and the tiger go to the bridge over the river (河). “Now look down at the water.” says the monkey. “Do you see the tiger?” “Yes, I do,” says the old tiger. “Let me eat him.” Then the tiger jumps (跳) into the river.
