虚拟语气口诀与总结
虚拟语气总结
（1）一种定语从句：It’s time that+did
（2）两种目的状语从句：
so that/in order that+ can/may/could/might +do
in case\lest\for fear(以防) that+should do
（3）三种随时变化句：
①wish 现在→did/were
if only ＋过去→had done
as if/though 将来→could/would do
②would rather＋/将来→did/were
过去→had done
③现在：if+did/were, would+ do
过去：if+had done, would+ have done
将来：did
if+ were to do, would+ do
should do
注意：除了由if引导的虚拟条件句外，还有倒装条件句，即把were、had或should提前；混合时间句，虚实错综句，以及含蓄条件句，即由or, otherwise, with, without, but for来引导的。
（4）四种名词性从句：
①当表语是important, natural, necessary, possible, strange, arranged, decided, demanded, ordered, requested, suggested, surprising, a pity, no woder时，主语从句要用虚拟语气。
例：
It’s important that we (should) help each other.
②动词一坚持(insist)，两命令(command, order)，三建议(advise, propose, suggest)，四要求(ask, demand, request, require)后的宾语从句要用虚拟语气。
例：
He insisted that he (should) be sent to the West.
注：insist(坚持说), suggest(暗示，表明)时，从句应用陈述语气。
如：
Her pale face suggested that she was ill.
1). Mother insisted that John (should) go to bed before 9 o’olock.
对比：He insisted that I had taken away his dictionary.（不是建议、要求、命令或主张）
2). His suggestion that Tony (should) be invited to the party was refused.（同位语从句）
对比：His words suggested that he was very angry with me.（不是建议、要求、命令
③idea, plan以及表示“坚持，命令，建议，要求”等动词的同源名词作主语时，表语从句用虚拟语气。
例：
My suggestion is that we (should) hold a class meeting.
④idea, plan以及表示“坚持，命令，建议，要求”等动词的同源名词后的同位语从句要用虚拟语气。
例：
The office gave an order that his soldiers fight back bravely.
If +were/ did (动词过去式)，主语+情态动词（would, could, might, should）+do（用来表示对现在情况的假设）1). I don’t have a cellphone. If I had one , it would be convenient for me to contract others.
If +had done (过去完成式)，主语+情态动词（would, could, might, should）+have
done（用来表示对过去情况的假设）
1). If I had gone to the concert, I would have seen the famous singer.
If +were/ did (动词过去式)，主语+情态动词（would, could, might, should）+ do
were to do
should do （用来表示对将来情况的假设）
1). If I were not to take/ should take/ took the exam tomorrow, I would go shopping with you.
虚拟语气条件句的倒装：在虚拟语气条件句中，如果出现助动词were, should, had，
可省略if, 把这些词提到主语前面，变成倒装句。
1). Should he act like that again, he would be fined. If he should act like that again, he would be fined。
Were he to act like that again, he would be fined. If he were to act like that again, he would be fined.
If he acted like that again, he would be fined.（不可以倒装）
2). Had the doctor come in time last night, the boy would have been saved.
If the doctor had come in time last night, the boy would have been saved.
3). If I had time now, I would go to the film with you. （不可以倒装,因为句中的had不是助动词）
But for….--> If it were not for…../ If it hadn’t been for
1). But for the determined captain, all the passengers on board wouldn’t have been saved.
If it hadn’t been for the determined captain, all the passengers on board……
2). But for your rich parents, you wouldn’t live such a easy life.
If it were not for your rich parents, you wouldn’t live such a easy life.。
虚拟语气的规则总结
虚拟语气虚拟语气：表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。
一、if从句：（二）错综时间的虚拟句：通常情况下,在条件句中主句和从句的谓语动词所指时间一致, 但有时也可能指不同的时间,这时主句和从句的动作不是发生在同一时间，其动词形式要根据时间而定。
1. If I were you, I would have taken his advice. (从句指现在, 主句指过去)。
2. If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在)。
3. If we hadn’t been working hard in the past few years, things wouldn’t be going so smoothly.（从句指过去，主句指现在）。
4. If the weather had been more favorable, the crops would be growing still better.（从句指过去，主句指现在）。
5. If we had not got everything ready by now, we should be having a more terrible time tomorrow. （从句指现在，主句指将来）??（三）省略：If 从句中含有were, should, had时，可省略if并把were, should, had提前。
例如：Were I you, I wouldn’t quarrel with him.备注：注：would, should, could与might的选择：①一般常用would，如同在真实条件句中主句常要用will一样。
常译作“将、就会”。
如：If I knew him, I would ask him for help. 如果我认识他的话，我就会向他求助。
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。

巧学活记虚拟语气
巧学活记虚拟语气第一、条件虚拟语气条件虚拟语气是最常用的虚拟语气，在历年高考中也经常出现。
学生需要掌握基本的三种条件虚拟语气条件句：对现在表示虚拟；对过去表示虚拟；对将来表示虚拟。
例如：If I were you, I would refuse the money.I would have dropped by if we had time.If you came/were to come/should come tomorrow, I would give the book to you.当然，除了基本用法外，学生还需注意以下2点：1、if 省略句在条件句中可省略if, 把were, had, should提到句首，变为倒装句式。
例如：If I were you, I would take his advice.→Were I you, I would take his advice.If he had been in your position, he’d probably have done the same.→Had he been in your position, you’d probably have done the same..2、错综虚拟语气（混合虚拟语气）当条件句是表示对过去的虚拟，而主句表示对现在的虚拟，则用错综虚拟语气（混合虚拟语气）。
例如：If you had followed your advice, you would be better now.If you had studied hard before, you would be a college student.第二、含有should的虚拟语气含有should的虚拟语气，可分为2类：用于表示建议、愿望、命令等词后的宾语从句中；用于其它名词性从句中（包括主语从句、表语从句和同位语从句）。
1、表示建议、愿望、命令等词后的宾语从句中，可以归纳为“一坚持(insist)，二命令(order, command)，三建议(advise, suggest, propose)，四要求(demand, desire, require, request)”。

虚拟语气
一、虚拟语气的规则用法：
1主、从句都表示与过去事实相反：
从句的.谓语动词用：had + 动词过去分词;
主句的谓语动词用：情态动词 + have + 动词过去分词。
注意：能用于虚拟语气的情态动词只有四个：should, could, would, might.
使用哪一个情态动词要由句子含义决定，考试中出现最多的是could, would.
2 主、从句都表示与现在事实相反：
从句的谓语动词用：动词过去式(如果是be则只能用were)
主句的谓语动词用：情态动词 + 动词原形。
3 主、从句都表示与将来事实相反：
从句的谓语动词用：were to + 动词原形(重点)、should + 动词原形、动词过去式;
主句的谓语动词用：情态动词 + 动词原形。
二、虚拟语气的特殊应用：
1 would rather + 句子，这时句子谓语动词用一般过去时来体现虚拟语气。
2 if only 如果，要是...就好了，if only + 句子，这时句子一定要用虚拟语气。
