1,首先要认清，这是一个强调句，陈述句式是，it is three hours that it takes the boy whose family is poor to come to school. "it is ... that",强调三小时，然后花谁多少时间做什么事是“it takes sb. some time to do ..”这两点掌握了就能做对了。先C就是没有记清楚这个句式，是没有FOR的，
3，也是一个强调句，“是A，而不是B”可以用A instead of B, 或者A rather than B，选A就错在了instead后面少了一个of

31.强调句的正常顺序：
It is three hours that it takes the boy whose family is poor to come to school on foot.
它的一般疑问句形式是将is提前：Is it three hours that .....?
原句：It takes the boy whose family is poor to come to school on foot.家境贫穷的男孩步行上学要走三个小时。
33.也是强调句，还原成正常的句子：
What he did rather than what he said moved us.是他所做的而不是他所说的感动我们。
放在强调句中It is +被强调部分+that+句子剩余部分：
It is what he did rather than what he said moved us that moved us.
