       Once there was a clever farmer. Though he was poor, he decided one day to take the king a roast goose
(烤鹅) as a present. He had not had     1    to eat that day, and soon the     2    of the roast goose became too
much for him as (当…时) he     3    it to the king, so he ate one of its legs.
       When he came before the king and gave him the goose, the king     4    saw that it had only one leg.
       Now, the king     5    was born with one bad leg, so he had never been able to     6    properly (正常地).
When he saw the goose with only one leg, he thought the farmer had     7     this to laugh at him. Of course
he was very     8   . The farmer was told that if anybody laughed at the king, he would be    9    at once.
       "Where is    10    leg of the goose?" the king asked.
       "All the geese (goose的复数) in this    11   of the country have one leg only," the farmer answered.
       "Do you think I'm a fool (傻子)?" the king shouted. "   12    ," said the farmer, "if you look out of the
window, you will see geese with one leg by the   13   ."
        The king looked, and there the geese were    14    on one leg beside the water. The king at once told
one of his men to    15   them with a big stick, and of course, they    16    their other legs and ran away.
        "There," said the king. "You were lying (说谎). That    17    that the geese here have two legs, like all
other   18   in the country."
        "But it doesn't show anything," answered the farmer, "if your men threw a big stick like that at me, I
would grow two    19   legs myself to help me to run away    20   ."
