教师寄语: Actions speak louder than words.

倒装句之部分倒装

部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。

　1)　句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until... 等。

Never have I seen such a performance.

Nowhere will you find the answer to this question.

Not until the child fell asleep did the mother leave the room.

当Not until引出主从复合句，主句倒装，从句不倒装。

注意 如否定词不在句首不倒装。

I have never seen such a performance.

The mother didnt leave the room until the child fell asleep.
