2016年职称英语卫生类语法：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 didn't leave the room until the child fell asleep.
