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。
顺便说一句，以上移至句首的 had不一定是助动词，如果是实义动词也可倒装：
If he had money，he would buy a car.
→Had he money，he would buy a car.
他要是有钱，他就会买一辆小车。

虚拟语气 倒装
四级语法辅导倒装㈠．英语句子的语序英语句子通常有两种语序。
一种是主语在前，谓语在后，称为自然语序（Natural order）.大部分的句子都采用自然语序。
另一种则相反，谓语在前，主语在后，称为倒装语序（Inverted order）.倒装语序又分为两类：1．全部倒装（Whole Inversion）:指包括表语或状语在内的整个谓语放在主语之前，它的语序是：表语或状语+谓语动词+主语。
2．部分倒装（Partial Inversion）指谓语中的一部分，如助动词do,does,did,情态动词can,may,should,ought to,must 等，“有”动词have, 系动词be等放在主语之前，其余部分包括谓语动词仍在主语之后。
㈡．分类与应用1．疑问倒装英语的疑问句一般采用倒装。
e.g. Has he left me a book?注：疑问词作主语或修饰主语时，句子不必倒装。
e.g. What makes him think so?2.惊叹倒装在由what和how引起的感叹句中，表语常常放在主语之前；在旧式文学体裁的陈述句中常出现主谓部分倒装表示惊叹：在美国英语中，有时用疑问句的倒装形式表示感叹。
如：e.g. What a wide river it is!Did he look annoyed!3.假设倒装在非真实条件句中，如if被省略,had,were,should需与主语倒装。
如：Had you(=If you had) asked me, I would have told you the answer.( 与过去事实相反) 4．副词倒装⑴．全部倒装a. here, there, now, then 置于句首而主语不是人称代词时。
e.g. Then came a girl.比较：Then she came.b. 小品词（如out,in,away,off等）或拟声词置于句首时。
e.g. In came the girls talking and laughing.⑵.部分倒装a. 方式副词或often, many a time频度副词置于句首时。
虚拟语气与倒装句型
虚拟语气、倒装句型虚拟语气虚拟语气是通过特殊的谓语动词形式来表达的愿望、假设、怀疑、猜测或建议等语气，它不表示客观存在。
一、虚拟语气在单句中的用法常用来表示祝愿、采用固定的倒装句式。
例如：Long live the People ⨯s Republic of China!中华人民共和国万岁！be happy! 快乐！have a good time! 玩得愉快！ succeed! 成功！make progress! 进步！二、虚拟语气在复合句中的用法：1． 在非真实性条件句与主句中的用法1） 表示与现在事实相反如果我是你，我会接受邀请的。
If I had time,I would go there.如果我有空，我就去那儿。
2） 与过去事实相反例如：If you had come earlier,you couldn ⨯t/wouldn ⨯t have missed the bus.如果你早点来，你就不会错过那辆公共汽车了。
If he had seen you yesterday,he would have returned your book.如果他昨天见到了你，他就会还你的书的。
3） 与将来事实可能相反例如：If it should rain/were to rain/rained tomorrow,the sports meet would be put off.万一明天下雨，运动会就推迟。
（事实上明天下雨的可能性不大。
）If you dropped/should drop/were to drop the glass,it would break.万一杯子掉下来会打碎的。
4） i f 的省略如果条件句中有were,had,should 等助动词，可将if 省略，而把were,had 或should置于句首,来表达以if 引导的条件句的相同意思。
例如：Should it rain/were it to rain tomorrow,the sports meet would be put off./Had he seen May you 祝你you yesterday,he would have returned your book.5)条件句或主句的省略当有上下文或上下句中的语言环境暗示的时候，表示虚拟语气的从句或主句往往可以省略，以避免重复。
语法复习：虚拟语气和倒装句综合
语法复习：虚拟语气和倒装句知识总结与归纳：虚拟语气：是一种与事实（包括过去，现在或将来）完全相反的陈述，表示假设，愿望，怀疑，推测或后悔。
虚拟语气主要用于条件从句，让步从句和名词性从句。
虚拟语气句型中常见的动词形式：1. 动词过去式2. had done3. would/could/should/might do4. would/could/should/might have done5. were（一）虚拟语气用在与过去事实相反的假设的条件句中：表示假设，后悔或推测。
句型结构：If +主语+had been/done….，主语+should/could/might/would + have done….1. If the illness had been diagnosed a day earlier, it might have made all different.2. If she had told him about the danger, he would not have got hurt.3. If I had known more about giving first aid, I could have helped him.（二）虚拟语气用在与现在事实相反的假设的条件句中：句型结构：If +主语+were / 动词过去式，主语+should/could/might/would +do1. If I had HIV, I would know because I would feel sick.2. If I were you, I would give an AIDS patient a hug.3. 虚拟语气用在与将来的结果相反的假设的条件句中：句型结构：If +主语+were to do, 主语+should/could/might/would +doIf +主语+should doIf +主语+动词过去式（1）If we were to panic, we would not be able to help.（2）If the little girl should take piano lessons, she would have less free time.（3）If I were to live long enough to have a job, I would choose to be a doctor, helping these AIDS patients.注意：虚拟条件句的从句中如果有助动词were; had或should可以去掉if以后用倒装句语序。
