虚拟语气的省略与倒装如何运用到英语作文中
省略：
(1)The suggestion that he (should) be invited was rejected.
(2)It's necessary that he (should) take the exam first.
(3)He insist that she (should) go home in good time.
倒装：
(1)Had it not been for the determined captain,all the people on board wouldn't have been saved.
(2)Were it not for you, I wouldn't have been got this job.
英语语法中 虚拟语气 倒装的知识点
在if引导的虚拟语气条件从句中，若有should. were . had . 那么在书面语气中就可以省略if，将这几个词提到句首，构成倒装。
虚拟语气的省略
虚拟条件从句中的谓语动词如果是had，should，were 的话，可以省略连词If, 但要将主语和谓语动词实行全部倒装或部分倒装。
从句 主句
Had / Should /Were +主语….. 主语 + 谓语….
Had they time（=If they had time）， they would certainly come and help us．
Should it be fine（=If it should be fine）， we would go for an outing．
Were I you（=If I were you）， I would go．
Were he to start out today he would get there by Thursday.
Had he listened to me, John would not have failed.
故你的句子不对， 不能倒装
几道英语倒装及强调句选择是，望详细解答，谢谢
1、 The old couple has been married for 40 years and never once() with each other.
A they had quarreled B they have quarreled C have they quarreled D had they quarreled
这题我选的是D，错的，为什么选C，这类题目当中我总是不知道用 “have” 还是用“had” 请问如何分辨
【这道题你没有注意到时态，and 前半句的时态是现在完成时：has been married，所以后半句的时态应该和它保持一致，也用现在的时态】
2、 so difficult () it to live in an english-speaking country that i determined to learn english .
A i have felt B have i felt C i did feel D did i feel
这题我选B ，应该选D，与上题同样不知道在have 还是did 两者选择
【这是个倒装句，如果你不知道该选have还是did，就把原句改回正常语序，即：I felt it so difficult to live...，所以改为倒装时添加的是助动词did】
3、only when your identity has been checked, （）.
A you are allowed in B you will be allowed in C will you allow in D will you be allowed in
这题我选C, 为什么选D ？
【同第2题，only 开头的句子要用部分倒装，正常的顺序应该是 you will be allowed in，改为倒装时，助动词will 提前】
4、it was () back home after the experiments.
A not until midnight did he go B until midnight that he didn't go C not until midnight that he went
D until midnight when he didn't go
这题为什么选C，不选B呢，为什么用went ?
【这里考查的是 not...until 的倒装句的用法，你可以把它看做是固定句型，即 It was + not unti' that 从句】
5、() a postgraduate,i would at least master two foreign languages.
A should i become B were i to become C had i become D i should become
为什么用were 不用had 呢
【这里是 if 条件句虚拟语气的用法，完整的句子应该是 If I were a postgraduate】
6、() he ill-mannered ,() the laziest and the most irresponsible creature you could ever hope to meet.
A not only is ...but he is also B not only is ...but also C not only is ...but also is he D not only ,,.but als o
这题怎么选A，不选B 了的？
【A和B的不同就在于but also 后面的内容，这句话中 not only...but also...连接的是两个句子，not only 句中的谓语动词是 is，but also 后面也需要谓语动词，所以选 but he is also】
7、() a machine been so efficient and accurate as the electronic computer.
A more than ever before B never before has
C in the past ,there never has D formerly ther never was
这题就一点也不懂了，不知道选什么了
【原题中有个been，所以判断是完成时，从B和C中选，而C选项中的there be 句型使用错误，所以答案选 B，这句话的意思是：以前从来没有像电子计算机一样高效精确的机器】
8、Little () about him when i first met him in that company.
A have i known B had i known C do i know D did i know
这题跟一开始几题相似，分不清选had 还是did 还是have
【跟开始几个题一样，思路就是把倒装改成正常语序，即：I knew little about him when I first met him in that company，表示否定的单词little 提前时，句子用部分倒装，即添加助动词 did，所以答案选D】
