PETS语法辅导系列之:倒装句型c

五、only在句首要倒装的情况

Only in this way, can you learn English well.

Only after being asked three times did he come to the meeting.

如果句子为主从复合句，则主句倒装，从句不倒装

Only when he is seriously ill, does he ever stay in bed.

六、as, though 引导的倒装句

as / though引导的让步从句必须将表语或状语提前 （形容词, 副词, 分词, 实义动词提前）。

注意：

1) 句首名词不能带任何冠词。

2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语,　 随实义动词一起放在主语之前。

Try hard as he will, he never seems able to do the work satisfactorily.

注意:

让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。

七、 其他部分倒装

1)　 so… that 句型中的so 位于句首时，需倒装。

So frightened was he that he did not dare to move an inch.

2)　在某些表示祝愿的句型中：

May you all be happy.

3)　在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。

Were I you, I would try it again.

典型例题：

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

A. man did know　 B. man knew　 C. didn’t man know　 D. did man know

答案为D.　否定词Not在句首，要求用部分倒装的句子结构。

2） Not until I began to work ___ how much time I had wasted.

A. didn’t I realizeB. did I realizeC. I didn’t realize　D. I realize

答案为B。

3)　Do you know Tom bought a new car?

I don’t know, ___.

A. nor don’t I care　 B. nor do I care

C. I don’t care neither　D. I don’t care also

解析：答案为B.　句中的nor引出部分倒装结构，表示"也不"。由 so, neither, nor引导的倒装句，表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
