     One day a farmer went out for a walk  with  his  daughter. The farmer put on a pair of wrong shoes

one with a thick sole (鞋底)  and the other  with  a  thin  one. So  as  he  began  to  walk, he  felt very

uncomfortable. When he was just out of the house, he  turned  to  his  daughter and said, "Why should

one of my legs be longer than the other today?"

     The daughter looked at his father's legs carefully as he  was  walking, and  then  laughed, "Oh,  no,

Daddy, your legs are all right. You have put on the wrong shoes."

     The farmer was very happy to hear that and said to himself, "What  a  clever  daughter  I  have got!"

Then he asked his daughter to go back and get the other pair of shoes for him.

     The farmer had only two pairs of shoes.

     When the daughter ran back to the house, she found  that  the  other pair was also  a  pair of wrong

shoes.

     She had to return to his father with nothing in her hands and said out of breath, "It's no use changing

them, Daddy! The shoes at home were not a pair, either!"
