Tom was a 16-year-old student. His father about him because he had no courage at all. Tom's father wanted his son to be a(n) man. So he decided to call on a master(大师) to train his boy. The master said to the boy's father, "You should leave son alone here. I'll make him into a real man three months. However, you can't come to see him during this period. "
Three months later, the boy's father returned. The master arranged(安排) a boxing(拳击) between the boy and an experienced boxer.
Each time the fighter struck(击打) the boy, he fell down, the boy stood up at once. Each time a punch(拳) knocked him down, the boy stood up again. Several times later, the master asked, "Now do you like your child?"
"What a shame!" The boy's father said, "I never thought he would be so knocked down. I don't have to leave him here any longer. "
"I'm sorry that's you see. Don't you see that each time he falls down, he stands up again and doesn't give up? If you want him this kind of courage, he does a good job. " Finally, the boy's father understood what the master said.
