虚拟语气倒装

虚拟语气倒装

当虚拟条件句中含有were，had，should，could等动词时，可以将if省略，然后将were，had，should，could 等词移至句首：

1）If he should fail，he would kill himself.

→Should he fail，he would kill himself.

万一失败，他就会自杀。

2）If I were you，I would do it at once.

→Were I you，I would do it at once.

假若我是你，我就会马上做。

3）If I could do it，I would.

→Could I do it，I would.

要是我能做此事，我一定会做。

4）If he had seen you yesterday，he would have asked you about it.

→Had he seen you yesterday，he would have asked you about it.

他昨天要是看到了你，他就会问你这事了。

再看一些例句：

1）Were they here now, they could help us.

=If they were here now, they could help us.

他们现在在的话，就会帮助我们了。

2）Had you come earlier, you would have met him.

=If you had come earlier, you would have met him.

你来得早一点，就碰到他了。

3）Should it rain, the crops would be saved.

=Were it to rain, the crops would be saved.

假如下雨，庄稼就有救了。

4）Were I（= If I were）in your place，I wouldn’t do it．

5）Had you（= If you had）seen it，you would have believed．

6）Were they to get married（= If they were to get married），the would not be happy．

7）Should he come，tell him to ring me up.

他要是来了，让他给我打个电话。

8）Were I in your position，I would go.

如果我处于你的地位，我就去。

9）Had they not helped us，our experiment would have failed.

如果没有他们的帮助，我们的试验是会失败的。

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 realize

B. did I realize

C. 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

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。

4）_____ to do the work, I should do it some other day.

A. If were I

B. I were

C. Were I

D. Was I

答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do, 而不能说Weren't I to do。

5）__________ your address，I would have written to you.

A. Did I know

B. Were I to know

C. Had I known

D. If I should know

此题应选C。这是虚拟语气的倒装形式。
