一、总论：虚拟语气主要用来表示假设，所陈述的是一个条件，不一定是事实，也有可能与事实完全相反。

二、写作素材：1.没有你的帮助，我不会成功。
I couldn't have succeeded without your helpWithout your help, I would not have succeed.2.要不是你的指导，我不会取得如此大的进步。

虚拟语气用法总结及详细解析
虚拟语气用法英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。
1、表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。
China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句)2、祈使句表示说话人对对方的请求、警告，建议或命令。
如:Please come over here. 请到这边来。
Watch your steps! 当心!(走路)3、虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。
此外，如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。
虚拟语气是由句中的谓语动词的特殊形式表示出来的。
如: If I were a bird，I would be able to fly in the air. 如果我是一只小鸟，我就能在空中飞行。
I wish I could pass the examination. 我希望我能通过考试。
If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。
If she were to be here next Monday, I would tell her about the matter.如果她下周一来这儿的话，我就会告诉她这件事的始末。
4、有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。
这种条件句叫错综条件句。
①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。
If I had worked hard at school, I would be an engineer, too.如果我在学校学习刻苦的话，我现在也会成为一个工程师了If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。

高考英语二轮专题语法复习虚拟语气语法讲义15if的隐含和省略以及与butfor相关虚拟语气知识点总结
高中英语语法学习/复习讲义虚拟语气语法知识点讲义15【精讲版·全国通用】if的隐含和省略以及与but for相关虚拟语气知识点总结虚拟条件句中if的隐含或省略语言是灵活多变的，表达是丰富多彩的。
有的时候虚拟语气的表现形式也显得非常灵活，比如就说其中的虚拟条件吧——它有时会以if从句来表示，但有时会用某种短语来表示，比如不定式短语、分词短语、介词短语等等。
1. if 的隐含I should be happy to go with you. 如果能与你一起去，我将很高兴。
句中的不定式短语to go with you就是表示虚拟条件的，它相当于if I could go with you。
这句话的言外之意是：可惜我不一定有机会同你一起去。
To have studied harder, you would have passed the examination. 你学习更用功些，你早就考及格了。
句中的不定式短语to have studied harder也是表示虚拟条件的，它相当于if you had studied harder。
句子的言外之意是：可惜你当时没有更用功我，所以你就没有考及格。
Failing this time, what would you do？假若这次失败，那你怎么办？句中的分词短语failing this time表示虚拟条件，相当于if you failed this time。
其言外之意是：尽管失败的可能性很小，但还是有可能会失败，假若失败了，那怎么办？Without your help, we couldn’t have succeeded. 如果没有你的帮助，我们就不会取得成功。
句中的介词短语without your help表示虚拟条件，相当于if you hadn’t given us help。
其言外之意是：好在你帮助了我们，所以我们取得了成功。
I didn’t know that he was a cheat, or else I wouldn’t have believed him. 我不知道他是个骗子，不然我也不会相信他了。

虚拟语气用法归纳完整版
虚拟语气用法归纳英语的动词一般可带有三种不同的语气：陈述语气，祈使语气和虚拟语气。
不同的语气用动词的不同形式（有的还借助句法形式）来表示。
一、虚拟条件句条件句有两类：一类是真实条件句，一类是虚拟条件句如果假设的情况是有可能发生的，就是真实条件句，谓语用陈述语气。
If you don 'work hard, you will fail.If it is fine tomorrow, we will go for a picnic.如果假设的情况过去、现在、将来都不存在，则为虚拟语气虚拟条件句和对应主句的动词形式列表：1•与现在事实相反的虚拟What would you do if you won the lottery?If I were you, I would seize the cha nee to go abroad.If I had a lot of money no w, I would travel around the world.2. 与过去事实相反的虚拟If you had bee n here yesterday, you would have see n her.If he had driven more carefully, he would not have had the car accident yesterday.3. 与将来事实相反的虚拟If it were to rain/should rai n/rai ned tomorrow, our pla n would be put off.If we were to pic nic, we would not be able to help.二、错综、混合虚拟语气通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。
混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。
