It is thought that people can easily tell whether a
person is a man or a woman from the clothes he/she wears. But now a lot of boys
and girls in America are wearing the same clothes and many of them all have long
hair. So it is often difficult to tell whether they are boys or girls.
One day, an old man went for a walk in a park in Washington. He felt a
little tired, so he sat down on a bench (长凳). There was a young person standing
on the other side of the pond (水池). "Excuse me," the old man said to the person
next to him on the bench, "Do you see the person with the red trousers and long
hair Is it a boy or a girl" "A girl," said the person next to him, "She is my
daughter." "Oh," the old man said quickly, "I am sorry, but I didn’t know that
you were her mother." "No, I’m not her mother," said the person, "I’m her
father." The old man thought the person next to him was the girl’s ______.
