一道英语选择题 并解释，

9.Is ____ three hours ____ the boy ___family is poor to come to school on foot?
A .it ;that; whose B. it; that it takes; whose C. it for ;that it takes; whose D. it; when ;that

Answer 1

B 原句是it takes the boy （three hours） whose family is poor to come to school on foot. whose family is poor 定语从句做定语修饰the boy
意思是这个男孩家庭贫困，需要花三个小时步行上学

此题变为陈述句是 it is three hours that it takes the boy whose family is poor to come to school on foot.
it is ……that …… 是强调句，用来强调three hours 这个时间 ，因为要强调，所以将three hours 提前 ，陈述句变为一般疑问句就是本题

Answer 2

正确答案应该是c
里面有个结构首先你得弄清楚it takes sb.time to do
其次有个强调句的结构it is that。。。
定语从句 whose 作主语
