Question

I don’t know the reason _____ you were absent from the meeting, and I am not sure that someone will tell me the reason _____ you haven’t told me.

A. why; that     B. that; why

C. because; why  D. of which; that

Answer

A

【解析】考查定语从句。用why是定语从句,就是why后面跟的句子整个修饰reason.而that是同位语从句,整个句子对reason起到了补充说明的作用.例：1)I don’t know the reason why he said these words.2) I don’t know the reason that he said these words.第一句是说他说这些话的原因,就是说他为什么要说这些话.第二句是说他说的这些话就是原因,原因的具体内容就是这些话.句意：我不知道妳缺席会议的原因，并且我不確定别人将会告诉我妳还没有告诉我的原因。故选A。

考点：考查定语从句和同位语从句。
