We were surprised to hear that the reason ( which )she gave for her absence was ( that )her mother was ill句子的主干:We were surprised to hear that(这个后面都是that指代的)其中:which she gave for her a...gave 后面不是双宾么？ 这样不就一个宾语了吗？ 不可以选A么，the reason whyis that 做一个状语①你说的双宾语是give sb sth? 问题是这里只是she give the reason额 非要那么说的话也可以理解成she give(us) the reason 不过没必要②像你说的 如果选A 句子变成了这样We were surprised to hear that the reason why she gave for her absence wasthat her mother was ill抛去We were surprised to hear that 看that后面的句子:the reason why she gave for her absence wasthat her mother was ill这里的why指代不了什么东西 give后面还是缺个宾语 这样说是可以的:the reason why she (wasabsent) wasthat her mother was ill注意括号里的变化the reason why后面一定是个完整的句子 因为什么什么的缘故 这个什么什么就是那个完整的句子
