     A lot of boys and girls in Western countries are wearing the same kind of clothes, and many of them have

long hair, so it is often difficult to tell whether (是否) they are boys or girls.

     One day, an old man went for a walk in a park, in Washington, and when he was tired, he sat on a chair.

A young person was standing on the other side of the pool.

     "Oh!" the old man said to the person sitting beside him on the chair. "Do you see that person with the

glasses and long hair? Is it a boy or a girl?" 

     "A girl," said the neighbour. "She is my daughter."

     "Oh!" the old man said quickly. "Please forgive me, I did not know that you were her mother."

     "I'm not." said the other person, "I'm her father."
