only after talking with her teacher did she know what to do句子结构详解!

成分:
she——主语;
did...know——谓语;
what to do——宾语;
only after talking with her teacher——时间状语从句.
句意:
只有在与老师谈过之后她才知道该做什么.
语法特点:
only位于句首,谓语动词用了部分倒装.即借了一个助动词did提到主语的前面.如果不用倒装(只是如果,事实上,英语这种情况都倒装的),这唏句话就应当这样说:
only after talking with her teacher she knew what to do.
不明白的继续追问哟!

倒装句,
当Only修饰的状语位于句首时,主句要用倒装语序.正常语序为:
She only knew what to do after talking with her teacher.
