     Once there was a king. He never ate a meal without fish. But one day there was a big storm (风暴) and

the fishermen were not able to go out to catch fish, so the king had no breakfast and no lunch. Then he

ordered his servants (仆人) to tell everyone in his country that if anyone brought him a fish, he would give

him anything he asked for.

     At last, a fisherman caught a big fish and hurried to the king's palace with it. But the king's prime minister

(宰相) stopped him and said, if the fisherman did not promise (答应) to give him half of whatever the king

gave him for the fish. He would not let the fisherman in.

     The king was very happy when he saw the fish. He said to the fisherman,"Now, what do you want for

your fish?"

      "I want you to beat (打) me twenty-four times" said the fisherman.

      The king was very surprised, and at last he said, "I promised to give you whatever you wanted, and I

think that I must keep my promise." So he began to beat the fisherman softly.

      "No," said the fisherman, "beat me as hard as you can!"

      After the king had beaten him twelve times, the fisherman jumped away and said, "That's enough for me.

I promised the other twelve to your prime minister."

      Again the king was very surprised, but the prime minister had to admit (承认) that the fisherman was

right. The king not only gave him the twelve beatings, but also said, "You will not be my prime minister."
