B.So did he;so l did
C.So he was;so was l
D.So was he;so l was
为什么

Answer 1

A,应该是So she did 吧.
So she did 是“确实是”的意思,So did I 是“我也是”的意思.助动词变了位置,意思就不一样了.
She is a good girl.要肯定的话回答就应该是“So she is ."
要是说我也是的话就是”So am I ."
So +be/助动词（do ,does ,did )/情态动词（can ,must)+主语,表示某某也如此.要是把主语跟助动词那些换一下位置,就成了对前面所说的肯定了.
如果前面是助动词,后面也用助动词,前面是情态动词,后面也用情态动词.
