问题补充：

I wonder when it was you came to realize he said meant.

A. that; what

B. what; that

C. what; what that

D. that; what what

答案：

A. that; what

B. what; that

C. what; what that

(答案→)D. that; what what

解析：句意：我不知道究竟是什么时候你意识到他所说的话的意思是什么。本句是一个多重复合句。I wonder后是when引导的强调句式的特殊问句，所以空一用that，realize后的宾语从句中的第一个what是动词meant的宾语，第二个what引导里面的主语从句。故选D。

考点: 考查从句连接词的用法。
