题目内容
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 |
D
解析试题分析：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。
