小升初必读语法: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, doesdid,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.

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.

典型例题

1) Why can't I smoke here?

At no time___ in the meeting-room

A. is smoking permitted B. smoking is permitted

C. smoking is it permitted D. does smoking permit

答案 A. 这是一个倒装问题。当否定词语置于句首以表示强调时,其句中的主谓须用倒装结构。这些否定词包括 no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.

2) Not until the early years of the 19 th century___ what heat is.

A. man did know B. man know C. didn't man know D. did man know

答案 D. 看到 Not until…的句型,我们知道为一倒装句,答案在 CD中选一个。

改写为正常语序为, Man did not know what heat is until the early years of the 19 th. 现在将 not提前,后面就不能再用否定了,否则意思就变了。
