___ he said so at the meering ,made everyone present surprise.选答案that ,what ,when ,\ 哪一个____ he said so at the meeting made everyong present surprised.此题选哪个答案?A.That B.What C.When D.\Was it not until you began to work ______
A.That
有so,就是有了他说的内容了,所以排除what
用when的话,后面就缺主语了
这是一个从句,不会空着不填
综上所述,选A.That

这里选A.....
没有so，选What...
如果when, 后面要改。。
When he said so at the meeting, he made everyone present surprised.

A that引导的主语从句
what因为已经有宾语so了所以不能选
