Question

She spoke so fast and left the room before they were able to understand ______ she said meant.

A．what

B．that

C．what what

D．what that

Answer 1

A

考查名词性从句。what she said meant做understood的宾语，what she said 做meant的主语， what做she said 的宾语。that引导从句，那后面应该是一个完整的句子，而 she said meant不是一个完整的句子。故选A。
