so...that引导的倒装句

在讲到部分倒装时会举这种例句：So cold was the weather that we had to stay at home.但主句中weather后没成分了啊，主系表完全倒置了啊，不应该是完全倒装吗，请解答

这个句子仍然是部分倒装，但给人感觉仿佛是完全倒装。

对于主系表结构的倒装，因为系动词be 本身也是操作词，所以，仅需把它提到主语前即可。比如：

So excited was Mike that he forgot to bring me the gift. 迈克是这样开心，居然忘记给我带礼物了。

So good a girl is she that we all like her. 她是一个这样好的女生，大家大伙都爱她。

但谓语动词若是实意动词，则要提前操作词（助动词或情态动词），实意动词仍在原位。比如：

So fast does light travel that we can hardly imagine its speed. 光速这样之快，大家几乎没法想象它的速度。

So well did our group do in the experiment that we were praised by our teacher.

大家组的实验做得这么好以至于得到了老师的表彰。
