    A farmer (农夫) wants to eat food every day, but he doesn't like working. He often

goes to other farmers' homes. When they eat, he eats with them, so other farmers don't

like him. One day, he sees a hare (野兔) running down the hill. The hare knocks against

(撞上了) a tree in his field, breaks its neck and falls dead (死了). The farmer is happy

and says,"Great!" He goes to the tree and gets the dead hare, and goes home with it. That

day, he eats a lot. He thinks that the meat is very good. The next day, he puts down his
