问题补充：
A father is very worried about his son, 【小题1】acts like a coward. So his father paid a visit to the master and 【小题2】(ask) him to train his son.
The master said, “I promise I’ll be able to train your child into a real man in three months.”
Three months later, his father came 【小题3】(pick) the child. The master arranged a match 【小题4】the child and his coach to show the three-month training result.
At Round One, the child 【小题5】 (knock) down and fell to the ground. He stood up to meet the challenge. But he was knocked down again, and once again he stood up to fight... this was repeated six times.
The master asked his father, “Do you think your child’s performance is【小题6】 of a man?” The father said, “I feel ashamed for 【小题7】 ! I never expected that he would be so weak after three【小题8】 (month) training.” The master said, “I don’t agree with you, and I regret that you only see 【小题9】 surface of things. You have not seen the courage and perseverance 【小题10】 your son. This is the very spirit of a man!”who
答案：
(答案→)who
解析：
【小题1】who 本句是一个定语从句，先行词是his son,关系代词who指代先行词在句中做主语。
【小题2】asked 本句的asked与前面的paid是一个并列结构，都使用一般过去时。
【小题3】to pick 固定搭配come to do sth来做某事。这位父亲来接儿子。
【小题4】Between 根据横线后面的the child and his coach，说明这个比赛是在教练和孩子之间进行的。
【小题5】was knocked本句是被动语态。指孩子被撞倒在地，但是站起来继续迎接挑战。
【小题6】that 代词辨析。这里的that指代不可数名词performance，后面有定语修饰。句意：你认为你孩子的表现是男人的表现吗？
【小题7】him 根据上文可知他送他的儿子来这里训练的，故使用宾格him，指代他的儿子。
【小题8】Months前面有基数词three修饰，说明这里使用复数形式。
【小题9】the 名词surface后面of things修饰，说明使用the表示特指。
【小题10】In本句句意：你没有看见你儿子身上的勇气和毅力。
