There once lived a boy named Woo Sing,     father brought home a mirror. Woo Sing had never seen one before. So when he saw it for the first time, he didn’t understand    it was, but thought he saw     boy, which made him very happy, for he thought the boy had come to play with him. He spoke to the stranger in a very friendly way, but received no reply. He laughed and waved at the boy, who did exactly     same thing. Then he thought, “I’ll go closer. It may be that he doesn’t hear me”. But when he began to walk, the other boy imitated（模仿）him. Woo Sing stopped     (think) about these strange actions, saying to himself, “This boy is fooling me. He does everything that I do;” and the more he thought about it, the     (angry) he became and soon he noticed the boy became angry too. So Woo Sing    (strike) the boy in the glass, but he only hurt his own hand and went   (cry) to his father, who said, “The boy you saw was    image. This should teach you an important lesson, my son. You should never show your anger to others. Now remember that in real life when you strike    cause you’ll hurt yourself most of all.”
