英语语法 虚拟语气的知识点归纳
英语语法虚拟语气的知识点归纳一、虚拟条件句(一)含有if条件句的主从句的虚拟语气总结：1. If 条件句中谓语动词的虚拟结构是在原来陈述语气所用时态的基础上倒退一个时态（对将来虚拟的were to do/should do例外）2. 主句要借助于情态动词的过去式，后跟动词原形（现在或将来）或have done(过去)；if条件句中只出现一个情态动词，即对将来虚拟的should.3.做此类题目时一定要分清是从句还是主句谓语动词的虚拟，还要把握好时态。
注意：1. 在虚拟条件从句中，动词“be”的过去时态一律用”were”，不用was。
2. 在虚拟条件状语中如果有were, should, had这三个词中任何一个，可省略if，把这三个词提到主语之前, 变成：were/should/had +主语+剩余成分。
3.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。
4.在表示与将来事实相反的条件句中，只能用should，而不能用would，could和might 等。
5.主句中的should通常用于第一人称，would，could以及might 可以用于各种人称eg :①If I were a bird, I could fly in the air.如果我是一只小鸟，我就能在空中飞行。
②I wish I could pass the examination.我希望我能通过考试。
在虚拟条件句中，对于与将来事实相反的情形，请注意以下几点：（1）条件从句表示的内容与将来事实相反，实为对将来情况的推测，用过去时表示虚拟；（2）条件从句谓语除用过去式外，有时也用“should+动词原形(表示可能性极小，常译为“万一”)”或“were to+动词原形(表示与将来事实相反的假设)”；（3）条件从句使用“should+动词原形”这样的谓语形式时，主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气形式外，也可用直陈语气或祈使语气。
虚拟语气句型
虚拟语气一、if 引导的虚拟条件句（表示与事实相反的假设）：现在：If+主语+过去式/were ，主语+should/would/could/might+动词原形过去：If+主语+had+过去分词，主语+should/would/could/might+have+过去分词过去式/were将来：If+主语+ should + 动词原形， 主语+should/would/could/might +动词原形were to + 动词原形另外：有些词，如：or ／otherwise （否则）；without （没有）；but for （要不是……）等，表示一个隐含的条件，所用的虚拟语气与if 引导的虚拟条件句结构相同注意：if 引导的虚拟条件句中，谓语部分含有were ／had ／should ，可将引导词if 省略，并将were ／had ／should 提到句首。
二、wish 之后接的宾语从句（表示不可能实现的愿望）：过去式/were （现在）Wish +（that ） had + 过去分词 （过去）would/could/might +动词原形 （将来）三、as if/as though 常与seem/look/appear 等动词连用，表示“看起来似乎……好象……”；以及if only 表示“要是……该多好啊”所用的虚拟语气结构与wish 结构相同；四、虚拟语气在名词从句中的运用：1、表示“命令”、“建议”、“要求”、“坚持”等词后所带的名词从句用虚拟语气，结构都是：（should ） + 动词原形，其中should 可以省略。
记忆口诀：insist2、动词 order +（that ）+ 主语+ （should ）+ 动词原形advise/suggest/recommend （宾语从句）require一坚持：insist 二命令：order ／command 三建议：advise ／suggest ／recommend 四要求：demand ／require ／request ／ask3、名词：advice/suggestion/order /request之后接表语从句或同位语从句，谓语部分也是用（should）+ 动词原形；4、在主语从句中：It is suggested/required/ordered/…that + 主语+ （should）+ 动词原形；It is important/strange/necessary/…that + 主语+ （should）+ 动词原形；过去式（现在／将来）五、would rather + sb. +had + 过去分词（过去）六、It is (high) time that + 主语+ 过去式鱼儿，在水中串上串下，吐着顽皮的泡泡；鸟儿从荷叶上空飞过，想亲吻荷花姑娘的芳泽。

虚拟语气(整理版)
虚拟语气(整理版)虚拟语气定义：虚拟语气指不行能实现的愿望或与事实相反的状况，而不表示客观存在的事实。
大致可分为以下几种状况：一、虚拟条件句（Unreal conditions）(一)含有if条件句的主从句的虚拟语气总结：1. If条件句中谓语动词的虚拟结构是在本来陈述语气所用时态的基础上倒退一个时态（对未来虚拟的were to do/should do例外）2. 主句要借助于情态动词的过去式，后跟动词原形（现在或未来）或have done(过去)；if条件句中只浮现一个情态动词，即对未来虚拟的should.3.做此类题目时一定要分清是从句还是主句谓语动词的虚拟，还要掌握好时态。
注重：1. 在虚拟条件从句中，动词“be”的过去时态一律用”were”，不用was。
2. 在虚拟条件状语中假如有were, should, had这三个词中任何一个，可省略if，把这三个词提到主语提之前, 变成：were/should/had +主语+剩余成分。
3.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 todo。
4.在表示与未来事实相反的条件句中，只能用should，而不能用would，could和might 等。
5.主句中的should通常用于第一人称，would，could以及might 可以用于各种人称（二）混合虚拟条件句当假设条件句的主句和从句不表达同一时光的时候，我们应使用混合时光的假设条件句，动词的形式要分离按照它所表示的不同时光做相应的调节，变法同if条件虚拟句的主从句谓语动词变法。
（三）含蓄条件句在含蓄条件句中，我们常使用otherwise ，or, but以及with ，without ，but for开头的介词短语来代替条件句。
注：1. but for =1)If it weren’t fo r(对普通现在时虚拟)2)If it hadn’t been for(对普通过去时虚拟)2.分句（直陈）+otherwise/or+分句→对主句谓语动词的虚拟3.分句（对主句谓语动词虚拟）+but/unfortunately+分句（直陈）4.with/without/but for+宾语+句子（对主句谓语动词虚拟）填空：1. 假如现在不下雨的话, 我们就出去野餐了。

如：If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。
如：If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会，我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点，你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话，我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如：What would you do with a million dollars? (=if you had a million dollars)如果你有100万元，你会做什么？We couldn’t have finished the work ahead of time without your help. (=if we hadn’t got your help) 没有你的帮助，我们不可能提前完成这项工作。
