The grandfather said with a kind smile, "Let me tell you a story, my dear. When I was a boy at your 2 , I, too, sometimes hated others for 3 they did."

The boy listened to his grandfather carefully as he went on, "There are always two tigers in my4 . One is good and kind. And he is friendly to others. He gets on well with everyone around him, but5 is bad and unfriendly. Even the smallest thing will make him angry. For this reason, he can't think carefully all the time so he can easily6 with everyone. The two tigers both try to control(控制) me. It is7 for me to live with them in my heart."

After hearing the story, the boy8 his grandfather's eyes for a while and asked, "Which tiger control you, grandfather?"

"The one that I feed. I always take care of the good and kind tiger. I try to forget the bad and unfriendly tiger. So I9 hate others and hardly ever get angry," the old man said10.
