One day, a boy had a fight with one of his classmates. Then he1to his grandfather and told him his story angrily, "He is2bad," the boy said, "and I hate him."
The grandfather said, "Let me 3you a story. When I was a boy, I too, sometimes hated4for what they did. But hate will make you feel tired. It doesn't hurt your enemy but only hurt5."
As the boy listened carefully, the grandfather went on, "There are always two tigers inside my heart. One is good and kind. He gets on well 6everything around him. But the other is bad and unfriendly. He is full of anger. Even 7thing will make him angry. He fights with8all the time, and for no reason. He can't think carefully9he always hates others. It is difficult to live with these two tigers inside my heart. They both try to control（控制）me."
The boy looked at his10eyes and asked, "Which tiger always controls you, Grandfather?"
The old man said slowly in a serious voice, "The one that I feed. I always feed the good and kind tiger, so I never hate others and seldom（很少）get angry now."
