题目

Was it in the company ( )you have been working ( )you got to konw each other?
--Yes.it has been six yeas already.
A.that;that B.where;where C.where;that D.that;where
the answer is C,but I don't konw why!

答案

——Was it in the company ( )you have been working ( )you got to konw each other?
——Yes.it has been six yeas already.
疑问句可以变为陈述句,以便理解句子结构：
【It 】【was 】【in the company where/in which you have been working介词短语,被强调部分】【that】you got to konw each other.
It was in the 【company先行词 】【where/in which you have been working 定语从句】【that】you got to konw each other.
即就是说,被强调部分本身是个【介词短语,其中company又带有定语从句】,后面才是强调句的that.
祝你开心如意!
