参考答案与简析：
1. C。一些表心理活动的动词（如think， suppose，guess， hope等）可用“过去完成时或一般过去时后接宾语从句”表示一个“与事实不符的过去的想法、猜想或希望”。
2. D。可用“should / would + have liked / loved + to do sth.”表示“过去本来想要做某事而未曾做到”。
3. A。可用“was / were + to have done sth.”表示“过去本来计划、安排做某事，但并未做到”。
4. C。可用“would rather + have done sth.”表示“主观上本来宁愿做某事，而实际上却没有做”，用否定式则表示“主观上本来宁愿不做某事，而实际上却做了”。
5. B。be supposed有“应该”之意，后面只接不定式，若不定式用完成式，表示“过去本来应该做某事，而实际上没有去做”，用否定式意思相反，此用法也含有批评、责备、抱怨之意。
6. D。当if条件状语从句表示对过去情况的假设时，从句谓语用had done，主句用would have done。
7. D。有时虚拟if条件从句不出现，而是通过某些词语（如otherwise， or， without， but for， but等）暗示虚拟语境，这时句子要用虚拟语气，注意要准确判断时间，决定句子谓语动词形式。此题显然与过去相关。

篇6：考研英语虚拟语气三种用法
考研英语虚拟语气三种用法
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气， 表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气。
下面，英语考研辅导专家们就为广大的的考生们详细地分析一下虚拟语气的三种用法，以供大家参考。
一、虚拟语气在状语从句中的运用
虚拟语气在状语从句中的运用除了可以表示条件外，还可以表示比较、结果、目的等。虚拟语气用于表示条件的状语从句中，一般称为虚拟条件句。根据时间的不同，虚拟条件句中谓语动词时态的变化可能有三种形式，即现在、过去和将来。
If it did, it would open up its diversity program, now focused narrowly on race and
gender, and look for reporters who differ broadly by outlook,values, education,
and class。( TEXT1)
这是一个含有条件状语从句的复合句。If it did是条件状语从句。主句中主语是it；谓语动词有两个，分别是would open up.。.和look for...。
这是一个与现在事实相反的虚拟语气，从句用一般过去时，主句用would+动词原形open up和look for。
参考译文：如果它能注意这个问题的话，它就会拓展其雇员多样化项目，而目前的项目只单纯考虑招收不同种族和性别的员工，去雇佣那些在世界观、价值观、教育背景及社会阶层方面各不相同的记者。
二、虚拟语气在名词性从句中的运用
虚拟语气除了用作状语从句中外，还可以用作主语从句、宾语从句、表语从句、同位语从句等名词性从中。
第一， 虚拟语气在主语从句中的运用
当it作形式主语，后面用形容词作表语，即在it is + adj。这样的句型中，当描述主语的表语形容词是advisable，critical，crucial，desirable，essential，imperative，important，
incredible，inevitable，necessary，recommend，strange，urgent等形容词时，主语从句的谓语动词多用虚拟语气，如果是现在时，谓语动词用should/would +动词原形(should/would经常省略)；如果是过去时，则用should/would + have done的形式。
It was inevitable that this primacy should have narrowed as other countries grew
richer. Just as inevitably，the retreat from predominance proved painful。
这是一个含有主语从句的复合句。句首的It是形式主语，真正主语是that从句，该主语从句使用了虚拟语气should+完成时。( TEXT1)参考译文：随着其他国家日益富裕，美国的这一优势地位逐渐下降是不可避免的。惟其不可避免，从优势地位上退出愈发痛苦不堪。
第二， 虚拟语气在宾语从句中的运用
表示“建议、请求、命令、要求”等主观意向的词(如：suggest、advise、assume、decide、demand、desire、insist、propose、order、recommend、require、suggest……)，引导宾语从句时需用虚拟语气。虚拟语气中的格式很固定：谓语动词用should+动词原形，should可以省略。注意这种句型中的虚拟语气形式不受主句动词时态的影响。Theories concerning on the individual suggest that children engage in criminal
behavior because they were not sufficiently penalized for previous misdeeds or that
they have learned criminal behavior through interactions with others。( CLOSE)
此句是个含有一个宾语从句、两个原因状语从句的复合句。suggest是主句谓语，Suggest后面的宾语从句中的谓语动词engage in前面省略了should。
参考译文：关于个体研究的理论认为，孩子们从事犯罪活动是因为以前他们做错事情时对他们的惩罚力度不够，或是因为他们通过与其他人的交往学会了犯罪。
第三， 虚拟语气在同位语从句中的运用
名词advice、assumption、decision、demand、desire、insistence、order、proposal、requirement、recommendation、suggestion……后面若有同位语从句，从句的谓语动词也应使用虚拟语气的形式。
Such behaviour is regarded as “all too human”，with the underlying assumption that
other animals would not be capable of this finely developed sense of grievance. ( TEXT1)
这是个含有同位语从句的复合句。that引导的同位语从句的.谓语动词由would+动词原形be构成。
参考译文：这样的行为被认为“完全是人类独有的特点”，其潜在的含义是其它动物没有这种敏锐的委屈感。
第四，虚拟语气在表语从句中的运用
与同位语从句一样，若主语是某些特定动词的同根名词(参考上一部分同位语从句)，要在它后面的表语从句要用虚拟式。
Another decision is whether the school should be one of the vast majority financed
by the State or one of the very small but influential minority of private schools，
though this choice is，of course，only available to the small number of those who
can pay. (英语专业四级考试Text D)
这是个含有表语从句的复合句。主语是another decision；谓语是is；whether……or……是表语从句，其中谓语动词由should＋动词原形be构成。参考译文：另一个要做出的决定是：应该选择一所占绝大多数的国立学校呢，还是选择一所数量虽小却有影响力的私立学校呢，当然，只有少数有支付能力的人才有这种选择的权利。
总之，虚拟语气是考研英语中的重要考点，频繁地出现在历年真题中。所以，考研辅导专家们温馨提示，20的考生在平时备考中一定要认真复习，理解它在不同语境中的用法。
。篇7：would rather虚拟语气用法总结
would rather的.近义词：as soon.
as soon.
释义：宁愿。
语法：指未发生的动作。时态规律是“主将从现”，即主句用一般将来时，从句用一般现在时代替一般将来时。
例句：
As soon as we found this out, we closed the ward.
我们一发现此事就关闭了病房。
篇8：without虚拟语气的用法总结
without作表语的用法
without引出的'介词短语通常用作状语,但有时也可用作表语.如：
She is completely without shame.她恬不知耻.

篇9：虚拟语气的用法
一、虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。也可用于主语从句、
表语从句、宾语从句等。
二、if条件状语从句中虚拟语气的判断
判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子
意思，看假设的条件是否能够实现，能够实现是真实条件句，不能使用虚拟语气；假设的条件
不能实现则是非真实条件句，要用虚拟语气。
判断这个假设是与哪个事实相反。通常有三种情况：①与过去事实相反。②与现在事实相
反。③与将来事实可能相反。
三、“后退一步法”
后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从
句谓语动词的时态。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就
是：
①与过去事实相反，在从句中用过去完成时形式表示。
②与现在事实相反，在从句中用过去一般时形式表示。
③与将来事实可能相反，在从句中用过去将来时形式表示。
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。
例：If I had come her yesterday, I would have seen him.
If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn't go out.
四、注意事项
①if条件句中如有were, should, had，可以省去if，并使用倒装语序。
②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
->宾语从句中的虚拟语气
一、wish 后面宾语从句中的虚拟语气
wish 后面宾语从句中的虚拟语气，按“后退一步法”处理从句的谓语动词。注意：与哪
个事实相反，不能以主句的时态为判断依据，而是根据从句的意义判断。
二、表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有：
advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose,
request, suggest等。
注意：当insist表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。
The look on his face suggested that he was quite satisfied with what I had done
for him. He insisted that he was honest.
三、would rather ＋从句
在这种结构中，从句的位于动词用过去形式表示虚拟。
I would rather you did this instead of me.
->主语从句中的虚拟语气
一、It be + 形容词 + that ．．．（should）．．．
用于该句型的形容词是：necessary, good, inportant, right, wrong, better, natural,
proper, funny, strange, surprising ．
一些名词也可以用于 在该结构中。如：a pity， no wonder．．．．
二、It be + 过去分词 + that ．．．（should）．．．．
用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如：desired，
suggested， requested， ordered， proposed等。
三、It is time（about time， high time）that ．．．（过去式动词形式或should＋动词原形）
．．．．
It is high time I went home now. = It is high time I should go home now.
->表语从句、同位语从句中的虚拟语气
在suggestion， proposal， order， plan， idea， advice， decision等需要有内涵的名词后
面的表语从句、同位语从句中，要使用虚拟语气。其谓语动词应用：should＋原形动词。另外连
接从句的that不能省略。
例：My suggestion is that weshould go there at once.

篇10：虚拟语气的用法
虚拟语气有哪些用法
1.虚拟条件句的`三种基本类型：与现在事实相反、与过去事实相反、与将来事实相反。
2.与现在事实相反，条件从句的谓语用过去式，主句谓语用should（would,could,might）+动词原形。
3.与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用should（would,could,might）+have+过去分词。

篇11：虚拟语气的用法
虚拟语气表示说话人的愿望、假设、猜测或建议,而不表示客观存在的事实。虚拟语气通过谓语动词的特殊形式来表示。下面分别介绍虚拟语气在各种句式中的用法。
1. 虚拟语气用于条件状语从句
注意:主句中的should通常用于第一人称,would可用于任何人称,同时也可根据意思用情态动词could, might等代替should, would。
1)表示与现在事实相反:
If I were you, I should stay at home.
If the peasants could farm the land themselves, food production would be much higher.
If fewer cash crops were grown, more food could be produced and there would be less or no starvation.
2)表示与过去事实相反:
If you had come yesterday, you would have met him.
If the hurricane had happened during the daytime, there would have been many deaths.
3)表示与将来事实相反:If you came tomorrow, we would have the meeting.
If it were to/should rain tomorrow, the meeting would be put off.
If it should rain, the crops would be saved.
4)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,动词的形式要根据它所表示的时间来调整。例如:If you had followed the doctor's advice, you would be quite all right now. (从句说的是过去,主句指的是现在.)
5)以上句型可以转换成下列形式:①从句省略if,用倒装句式“were, had, should+主语”。例如:Were I in school again, I would work harder. Had you been here earlier, you would have seen him. Should there be a meeting tomorrow, I would come.②用介词短语代替条件状语从句。例如:Without air, there would be no living things. I would not have succeeded but for your help.
2.虚拟语气用于宾语从句
1)“wish+宾语从句”表示不能实现的愿望,汉语可译为“可惜……”、“……就好了”、“悔不该……”、“但愿……”等。表示现在不能实现的愿望,从句的谓语动词用过去式;表示将来不能实现的愿望,用“would(could)+动词原形”;表示过去不能实现的愿望,用“had+过去分词”或“(could)would + have + 过去分词”。例如:
I wish we could go to the seaside today.
I wish you told me earlier.
We wish we had arrived there two hours earlier.
2)虚拟语气在动词arrange, command, demand, desire, insist, order, propose, request, require, suggest 等后面的宾语从句中,用“(should)+动词原形”。例如:
I suggested that the meeting (should) be put off.
The doctor ordered that she (should) stay in bed for a few days.
They demanded that the black people should be treated as well as white people.
注意:insist作“力言”、“强调”解时,宾语从句不用虚拟语气。只有当insist作“坚持(应该)”解时,宾语从句才用虚拟语气。例如:
Mike insisted that he had never stolen anything.
I insisted that you give me my money back.
3.虚拟语气用于表语从句、同位语从句做advice, idea, order, demand, plan, proposal, suggestion, request 等名词的表语从句和同位语从句,其谓语动词要用虚拟语气的结构“(should)+动词原形”。例如:
We all agreed to his suggestion that we (should)go to Beijing for sightseeing.
My idea is that he (should) do exercises first.
4.虚拟语气用于以as if(as though)引导的表语从句或状语从句
如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用“had+过去分词”;表示与将来事实相反,谓语动词用“would(might, could )+动词原形”。例如:
He looked at me as if I were mad.
He speaks English so fluently as if he had studied English in England.
It looks as if it might rain.
但as if(as though)后的从句也常用陈述语气,这是因为从句中的情况往往是可能发生的或可能被设想为真实的。例如:
It looks as if our side is going to win.
5.虚拟语气用于主语从句
在主语从句中,谓语动词的虚拟语气结构用“should+动词原形”的结构,表示惊奇、不相信、惋惜、理应如此等。例如:
It is necessary (important, natural, desirable, advisable, strange, etc.) that we should clean the room every day.
It was a pity (a shame, no wonder, etc.) that you should be so careless.
It will be desired (suggested, decided, ordered, requested, proposed, etc.) that she should finish her homework this afternoon.
在上述三种主语从句中,should意为“应该”、“竟然”,可以省去,但不可换用would。主句所用动词的时态不限。
注意:这种从句表示的是事实。如果说话人对这种事实表示惊奇,就可用虚拟语气。反之,如果不表示惊奇,that从句也可用陈述语气。例如:
It is strange that he did not come yesterday.
It is a pity that you can't swim.

篇13：虚拟语气用法简介
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事条件状语从句分类
一 . 条件句
1、表示与现在事实相反的情况：
从句：If 主语+过去时(Be动词用were) 主句：主语+should/would/could/might+do
2．If I knew his telephone number,I would tell you.
如果我知道他的电话号码，我就会告诉你。（事实：不知道）
2、表示与过去事实相反的情况
从句：If 主语+had+done主句：主语+should/would/could/might+have done
1． If I had got there earlier,I should/could have met her. 如果我早到那儿，我就会见到她。
3、表示对将来情况的主观推测
①if+主语+were to do 主句：①主语+should/would/could/might+do
②if+主语+did/were ②主语+should/would/could/might+do
③if+主语+should+do ③主语+should/would/could/might+do
1．If he should come here tomorrow,I would talk to him.
如果他明天来这儿的话，我就跟他谈谈。（事实：来的可能性很小）
2．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。（事实：下雪可能性很小）
3．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。（事实：来的可能性很小）
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.
If they had informed us,we would not come here now.
②从句的动作与现在事实相反，而主句的动作与过去事实不符。
If he were free today,we would have sent him to Beijing.
5、当虚拟条件句的谓语动词含有were,should,had时，if可以省略，这时条件从句要用倒装语序，即把were,should,had等词置于句首，这种多用于书面语。eg：
Should he agree to go there,we would send him there.
Were she here,she would agree with us.
6、非真实条件句中的条件从句有时不表达出来，只暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句，在多数情况下，条件会暗含在短语中，如without…，but for…等
But for his help,we would be working now.
Without your instruction,I would not have made such great progress.
二.wish 后宾语从句
a、表示与现在事实相反的愿望，谓语动词用过去式
eg. I wish I had your brains.
b、表示与过去事实相反的愿望，谓语动词：had+done
eg:.I wish I had known the truth of the matter.
(注：if only引导的感叹句和as if/as though引导的状语从句也有相同用法）
三.目的状语从句
1、在for fear that,in case,lest引导的从句中，若用虚拟语气时，从句谓语为：should + do。并且 should能省略
She examined the door again for fear that a thief (should) come in.
He started out earlier lest he (should) be late.
四. 其他用法
1、一想要(desire一宁愿(prefer)一坚持（insist）二命令(order. command)三建议(advise. suggest. propose/recommend)四要求(demand. require. request. ask)中，无论主句谓语动词为何种时态，从句的谓语动词都用：“should + do”。should可以省略。eg：
He suggestedthat we (should) take the teacher's advice.
He insisted that we (should) take the teacher's advice.
He demand that we (should) take the teacher's advice.
He orderedthat we (should) take the teacher's advice.
insist意为“坚持某种动作”才用虚拟语气；意为“坚持某种观点，某个事实”则不用虚拟语气。 He insists he is a student.
suggest意为“建议”才用虚拟语气，意为“暗示”则不用虚拟语气。
His face suggests that he looks worried .
2、表情绪.观点的形容词或名词也要用虚拟语气.如：necessary、important、impossible、natural、strange、surprising、funny、right、wrong、better、a pity ,the shame ,no wander等。
句型：It is.......that +主语从句，从句的谓语动词都要用should+原型 或只用动词原型。
eg:
It is strange that such a person should be our friend.
3、在even if,even though 所引导的让步状语从句中用may/might+动词原形，may/might可以省略，表示与现在相反的情况；从句用过去完成时，表示与过去相反的情况，类似的词有though/even though/whatever/however/so long as; 主句、从句的结构与if所引导的条件从句结构相同。
Even if he were here himself,he should not know what to do.
Nobody could save him even though Hua Tuo should come here.
5、一般would rather,had rather,would sooner等之后的宾语从句常表示与客观事实不相符的一种愿望，故使用虚拟语气。其虚拟语气的结构为：
过去 had + done 现在 过去时(be 用were )
将来 过去时(be 用were ) （would rather将来情况用一般过去时）
I'd rather you had seen the film yesterday.
I'd rather you were here now.
We'd rather you went here tomorrow.
6、虚拟语气还可用在定语从句中，表示：“早该做某事了”时，定语从句中的谓语动词须用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语+ 动词的过去式/ should + do（优先使用动词过去式），即从句用虚拟过去式。
It is time that I went to pick up my daughter at school.
篇14：关于as if虚拟语气的用法
有时用虚拟语气，若表示与现在事实相反，谓语动词用一般过去时;若表示与过去事实相反，用过去完成时;表示将来的可能性不大，用would (might, could)+动词原形。
英语语法网要特别提醒同学们，这是一个中考英语中的高频考点，同学们一定要多加注意。
它的常规用法相信同学们都很熟悉，今天小牛英语要跟大家强调两点罕见情况。
(1) 从句所表示的内容若为事实或可能为事实，也可用陈述语气：
It looks as if we'll be late. 我们似乎要迟到了。
This meat tastes as if it has already gone bad. 这肉吃起来似乎已经坏了。
在现代英语中，有时即使从句内容不是事实，也可能用陈述语气：
I feel as if [as though] I'm floating on air. 他感到好像漂浮在空中。
The stuffed dog barked as if it is [were, was] a real one. 玩具狗叫起来像真狗。
(2) 注意 It isn't as if…的翻译：
It isn't as if he were poor. 他不像穷的样子(或他又不穷)。
It isn't as if you were going away for good. 又不是你离开不回来了。
篇15：考研英语虚拟语气三种不同用法
考研英语虚拟语气三种不同用法
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气， 表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气。
下面，专家们就为广大的的考生们详细地分析一下虚拟语气的三种用法，以供大家参考。
一、虚拟语气在状语从句中的运用
虚拟语气在状语从句中的运用除了可以表示条件外，还可以表示比较、结果、目的等。虚拟语气用于表示条件的状语从句中，一般称为虚拟条件句。根据时间的不同，虚拟条件句中谓语动词时态的变化可能有三种形式，即现在、过去和将来。
If it did, it would open up its diversity program, now focused narrowly on race and
gender, and look for reporters who differ broadly by outlook,values, education,
and class。( TEXT1)
这是一个含有条件状语从句的复合句。If it did是条件状语从句。主句中主语是it；谓语动词有两个，分别是would open up.。.和look for...。
这是一个与现在事实相反的虚拟语气，从句用一般过去时，主句用would+动词原形open up和look for。
参考译文：如果它能注意这个问题的话，它就会拓展其雇员多样化项目，而目前的项目只单纯考虑招收不同种族和性别的员工，去雇佣那些在世界观、价值观、教育背景及社会阶层方面各不相同的记者。
二、虚拟语气在名词性从句中的运用
虚拟语气除了用作状语从句中外，还可以用作主语从句、宾语从句、表语从句、同位语从句等名词性从中。
第一， 虚拟语气在主语从句中的运用
当it作形式主语，后面用形容词作表语，即在it is + adj。这样的句型中，当描述主语的表语形容词是advisable，critical，crucial，desirable，essential，imperative，important，
incredible，inevitable，necessary，recommend，strange，urgent等形容词时，主语从句的谓语动词多用虚拟语气，如果是现在时，谓语动词用should/would +动词原形(should/would经常省略)；如果是过去时，则用should/would + have done的形式。
It was inevitable that this primacy should have narrowed as other countries grew
richer. Just as inevitably，the retreat from predominance proved painful。
这是一个含有主语从句的'复合句。句首的It是形式主语，真正主语是that从句，该主语从句使用了虚拟语气should+完成时。( TEXT1)参考译文：随着其他国家日益富裕，美国的这一优势地位逐渐下降是不可避免的。惟其不可避免，从优势地位上退出愈发痛苦不堪。
第二， 虚拟语气在宾语从句中的运用
表示“建议、请求、命令、要求”等主观意向的词(如：suggest、advise、assume、decide、demand、desire、insist、propose、order、recommend、require、suggest……)，引导宾语从句时需用虚拟语气。虚拟语气中的格式很固定：谓语动词用should+动词原形，should可以省略。注意这种句型中的虚拟语气形式不受主句动词时态的影响。Theories concerning on the individual suggest t
篇16：高中英语虚拟语气的用法
一、考查虚拟语气在条件从句中的用法
虚拟语气在条件从句中的用法是其最基本的用法，也是高考最可能涉题的用法。为了便于理解和记忆，我们虚拟语气在虚拟条件从中的用法分为三类--涉及现在时间的虚拟条件，涉及过去时间的虚拟条件，涉及将来时间的虚拟条件。下面就是这三类基本句型的谓语动词形式：
时间 从句谓语形式 主句谓语形式
将来 一般过去时(be用were) would/should/might/could+动词原形
现在 一般过去时(be用were) would/should/might/could+动词原形
过去 过去完成时 would/should/might/could have+过去分词

(1) -John went to the hospital alone.
-If he _______ me about it, I would have gone with him. (2010天津卷)
A. should tell B. tells C. told D. had told
二、考查特殊句型中的虚拟语气
英语中需要使用虚拟语气的特殊句型不多，主要有以下类：
1. “倒装”类虚拟语气
当虚拟条件句中含有were, should, had时，有时可将引导虚拟条件句的连词if省略，而将从句中的were, should, had 提到句首，构成倒装形式的虚拟语气。如：
If he were here, she would agree too. →Were she here, she would agree too. 如果她在这里，她也同意的。
If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match. 假若明天下雨，我们只好推迟这场比赛。
If we had found him earlier we could have saved his life.→Had we found him earlier we could have saved his life. 要是我们当时早点找到他的话，我们就可以救活他。
注意，如果条件从句的谓语为否定式，其中的否定词not应置于主语之后，而不能与were, should, had 等缩略成Weren’t, Shouldn’t, Hadn’t而置于句首。如：我如不是警告了你，你就可能丧命了。
正：If I hadn’t warned you, you could have been killed. 正：Had I not warned you, you could have been killed.
误：Hadn’t I warned you, you could have been killed. 另外，有时省略if后提前到句首的had可能不是助动词，而是实义动词。如：Had I time, I would go with you. 假如我有时间，我就同你们一起去。句中的had不是构成过去完成时的助动词，而是表示“有”，如果不省略if，其完整形式为：If I had time, I would go with you.
【有关考题】（答案分别为AB）
(1) Had I known about this computer program, a huge amount of time and energy _______. (2010浙江卷)

(1) _______ fired, your health care and other benefits will not be immediately cut off. (湖北卷)
A. Would you be B. Should you be C. Could you be D. Might you be
3. “宁愿”类虚拟语气
这里说的“宁愿”主要是指would rather。当它后接句子的时候，句子的谓语通常要用虚拟语气，其用法及结构形式为：若从句内容是涉及的是对现在或将来情况的希望，则从句谓语用一般过去时；若从句内容是涉及的是对过去已发生情况表示遗憾或后悔，则从句谓语用过去完成时。如：
I’d rather you went home now. 我希望你现在就回家。
Tomorrow’s difficult. I’d rather yon came next weekend. 明天有困难，我希望你下周末来。
I’d rather I had gone to the theatre last night. 我倒希望我昨晚我去了剧院看戏。(zn)

4. “建议”类虚拟语气
但是，若suggest表示“暗示”“表明”“指出”“提出(看法)”等，则从句谓语要用陈述语气。如：
His smile suggested that he was satisfied. 他的微笑表明他是满意的。

【有关考题】（答案为C）
The workers will go on strike if the demands they _______ put forward are turned down. (2006福建卷)
A. could B. would C. 不填 D. had
答案为C。
7. “坚持”类虚拟语气
这类虚拟语气主要指动词insist后接宾语从句时所用的虚拟语气--若从句内容是既成的事实，不容置疑，则从句谓语用陈述语气，此时insist的意思是“坚持说”；若从句内容虽然还不是事实，但非常希望它成为事实，从句谓语用虚拟语气，即采用“should+动词原形”的形式，且其中的should在美国英语中可以省略，此时insist的意思是“坚持要”。比较并体会：
He insisted that I had read his letter. 他坚持说我看过他的信。
He insisted that I should read his letter. 他坚持要我看他的信。
He insisted that he was not ill, but the doctor insisted that he should take the medicine. 他坚持说他没有病，但医生却坚持要他服药。
8. “愿望”类虚拟语气
这类虚拟语气主要指动词wish和固定搭配if only后所接从句使用的虚拟语气，但不包括动词hope在内。此类虚拟语气的结构特点如下：
从句所涉及时间 从句谓语形式
从句内容涉及现在情况 一般过去时 / 过去进行式
从句内容涉及过去情况 过去完成时 / would (could)+have +过去分词
从句内容涉及将来情况 would (could, might)＋动词原形
I wish I could swim. 我要是会游泳就好了。
I wish I had been here yesterday. 我真希望我昨天在这里。
I wish he could come tomorrow. 我希望他明天能来。
I wish you would come if you had time. 你如有时间的话，我希望你来。
If only I knew her name! 我要是知道她的名字就好了!
If only you had let me know earlier. 要是你早点让我知道就好了。
If only she would go with me! 她要是愿意和我一道去就好了!
9. “似乎”类虚拟语气
这类虚拟语气主要指由表示“好像”和“似乎”的as if以及as though引出的虚拟语气句子。既然是“好像”怎么样，或者是“似乎”怎么样，所以它描述的内容就不大可能是事实，或者说可能是非真实的，所以它的谓语通常要用虚拟语气，其结构形式与wish后从句的谓语形式差不多。如：
I’ve loved you as if you were my son. 我爱你就像我的儿子。
He talks as if he had a potato in his mouth. 他讲起话来仿佛嘴里含了一个土豆似的。
She looked as if she had seen a ghost. 她看起来好像刚才遇见了鬼似的。
根据各句的句意可知，“你”显然不是“我”的儿子，所以第一句中as if从句的内容是非真实的，故用虚拟语气；“他”说话的时候嘴里肯定没有含一个土豆，所以第二句中as if从句的内容也是非真实的，故也用虚拟语气；大家知道“鬼”是不存在的，所以她好像见到鬼的内容也是不真实的，所以第三句的as if从句也用虚拟语气。
但是，如果说话者认为as if或as though从句所表示的内容是真实的，或者说是有可能成为事实的，那么也可以使用陈述语气。如：
We’ve missed the bus. It looks as if we’ll have to walk. 我们错过了公共汽车，看来我们得走路了。
10. “时候”类虚拟语气
这类虚拟语气主要是指It’s time…（是做某事的时候了）后接从句时所使用的谓语形式--不管是针对现在还是将来的情况，一律使用一般过去时。如：
It’s time we ordered dinner. 现在该叫菜了。
It’s time you washed those trousers. 你该洗洗那条裤子了。
I’m getting tired. It’s time we went home. 我累了，我们该回家了。
另外，有时还可在名词time前加上修饰语high表示强调。如：
It’s high time you bought a new car. 你早该买辆新车了。
有一点值得注意，就是动词be在这类虚拟语气中的用法与其他的虚拟语气结构不同，前面我们讲到动词be在虚拟语气句式中通常在该用was的时候而用were，但是it’s time后的从句中，该用was的时候不能用were来代替。如：
大家都该上床睡觉了。
误：It’s time everyone were in bed. 正：It’s time everyone was in bed.
11. “若不是”类虚拟语气
英语中有三个表示“若不是”“要不是”的固定表达，它们总是用于引出虚拟条件，句子谓语总是用虚拟语气。这三个固定表达是but for, if it were not for, if it had not been for。如：
The car broke down. But for that we would have been in time. 汽车出毛病了。要不是那个我们会及时赶到的。
If it weren’t for your help, I would still be homeless. 若非你的帮助，我仍会无家可归。
If it hadn’t been for the doctor’s care, I wouldn’t have recovered so soon. 要不是医生的照顾，我不会痊愈得这么快。注：介词without有时也可表示虚拟条件，意为“若不是”“要不是”，与but for用法相同。如：
Without [=But for] your help, I would have failed. 要不是有你的帮助，我就会失败了。
但是，without也可以不表示条件，只表示“没有”的意思。如：
Without a word he left the room. 没有说一句话他离开了房间。

篇17：虚拟语气的几点特殊用法
1、在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。例如： 1）If I were you，I wouldn't have missed the film last night．如果我是你，我就不会错过昨天晚上的那部电影。（从句与现在事实相反，主句与过去事实相反。） 2）If he had followed the doctor's advice，he would recover already．如果他遵照医生的劝告，现在病就好了。（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should移到句首构成非真实条件从句的另一种句型，其意思不变。例如： 1）Had we time to spare，we would be glad to go to the park．如果能抽出时间，我们很乐意逛公园。 2）Were it not for the discovery of electricity，the modern world would experience great inconveniece．假如没有发现电，现代世界将很不方便。 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词（如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。例如： 1）But for your advice，I would not be able to do this work．要不是你的劝告，我是不会做这份工作的。 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．显然维克多不知道发生了什么事情。不然的话，他就不会说这样愚蠢的话了。 4、在一些表示愿望、建议、请求、命令等含义的动词后面的宾语从句中，谓语动词用动词原形或“should ＋动词原形”表示虚拟语气。这类动词有ask，demand， insist，order，propose，move，desire，require等。例如： 1）They demanded that the aggressor troops（should）be withdrawn immediately．他们要求立即撤出侵略军。 2）I moved that he（should）be discharged for his serious mistake．我建议，由于他犯有严重错误，应解除他的职务。 5、在“would（had）rather（would sooner，would as soon）＋宾语从句”句型中，要求后面的宾语从句用虚拟语气。但这种虚拟语气表示的不是与事实相反的假设，而是一种尚未实现的愿望，其从句谓语动词用一般过去时。例如： 1）I would rather you came next Friday．我希望你下周五来。 2）I'd just as soon you didn't speak rudely to her．我真希望你别对她那么粗鲁地讲话。 6、在和idea，necessity，plan， motion，order，proposal，recommendation，suggestion，under- standing等词有关的同位语或表语从句中，谓语动词用动词原形或“should ＋动词原形”表示虚拟语气。例如： 1）M y idea is that the group（should）hold another session to discuss the problem．我的意见是小组召开另一次会议来讨论这个问题。 2）Emphasis is laid on the necessity that all the objectives to be attained be taken into account before starting a new project．我们强调在开始制定一个新的计划之前，必须把要达到的所有目标都考虑进去。 7、在某些“It is ＋形容词＋that．．．”句型中，如“It is important（necessary，essential， natural，desirable，unusual，pity，strange）that．．．”，that所引导的主语从句中谓语动词均用动词原形或“should ＋动词原形”来表示虚拟语气。例如： 1）It is highly desirable that a new president be appointed for this college．人们迫切地希望能给这个学院派一个新院长。 2）It is strange that the girl（should）be so arrogant．真奇怪，这个女孩竟会如此傲慢。 8、在“It is ordered（suggested，demanded，moved，planned等）＋that．．．”这个句型中，that引导的主语从句要用虚拟语气形式，谓语动词用动词原形或“should ＋动词原形”。例如： 1）It is moved that Lucy give a performance at the party．有人提议露茜在晚会上表演一个节目。 2）It was suggested that more teachers （should）be sent there to help them．有人建议派更多的老师去那儿帮助他们。 9、as if ／though可以引出一个状语从句也可以引出一个表语从句。当as if ／though跟在be，feel，look，seem ，sound等系动词之后时，引导的是表语从句；如果主句的谓语动词不是联系动词be等，as if ／though引导的则是方式状语从句。无论是哪种类型的从句，只要从句的内容是不真实的，都必须用虚拟语气。当从句表示与现在的事实相反，谓语动词用一般过去时；表示与过去事实相反要用“had ＋过去分词”；表示与将来可能相反的则用“would（could，might）＋动词原形”。例如： 1）I feel as if I were going to faint．我感到我像要昏过去似的。（与现在事实相反的表语从句） 2）She cried as if her heart could be broken．她哭的好像心都要碎了。（与将来可能相反的主语从句） 10、在It is（about ／high）time引导的定语从句中，也可以根据需要使用虚拟语气，用以表示“（此刻）该做......而没有做”的意思，其谓语动词用过去时或“should ＋动词原形（用should时，不能将其省略）”。例如： 1）It is time I should leave．我该走了。 2）It is about time that you got（should get） dressed．你该穿衣服了。 11、if only引导的是省略了表示结果的主句的虚拟结构，现在已成为惯用法，表达愿望。从句用过去时表示现在没有实现的愿望；对过去没有实现或不能实现的愿望，从句就用过去完成时。这类句型表示一种不真实的条件，常译成“要是......就好了！”例如： 1）If only I had taken mother's advice．我要是听取妈妈的建议就好了。 2）If only I could speak several foreign languages．我要是能讲几种外语就好了。 12、在以in order that，so that，lest引导的目的状语从句中，谓语动词一般用虚拟语气。从句中的谓语动词用“may（might）＋动词原形”或“should ＋动词原形”。在以lest引导的从句中，谓语动词用“should ＋动词原形”。例如： 1）She stayed at home for a few days so that she might take care of her sick mother．她在家里呆了好几天，以便能照顾生病的母亲。 2）The teacher explained the sentences again and again in order that the students could understand them clearly．老师一再解释这些句子以便学生能够清楚地理解。

篇19：英语虚拟语气知识点
1、基础用法
2. 注意四个情态动词的用法
(1)若表示在某一假设的条件下，必然而然就会发生某事，第一人称可用should或would, 而二、三人称只用would.
(2)若表示在某一假设条件下就能够干某事，各人称都用could.
(3)如果表示在某种假设条件下有可能会发生某事，各人称都用might.
3.虚拟语气的倒装
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。
注意：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. Hadhe money，hewould buy a car.
(1)从句与过去事实相反相成，而主句与现在事实相反。例如：
If you had not been strict withme when I was young, I could not be such a successful person now.(这种虚拟语气的特点是主句中常含有时间准状语now
或nowadays)
(2)Should anyone come and ask for me, tell them I willcome back tomorrow.(主句为祈使句，条件句与将来事实相反，表示说话人认为某件事情发生的可能性很小。)
5.含蓄虚拟条件句
含蓄虚拟条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。这类用法主要见于以下七种方式：
(1)将条件隐含在不定式短语中。
I should be happyto go with you. (=I should be happy if I could go with you.)
(2)将条件隐含在分词短语中。
Born in bettertimes, he would have been a scholar. (=If he had been born in better times, he…)
(3)将条件隐含在介词短语中。
Without air, no onecould live. (=If there were no air, no one could live.)
常用的介词或介词短语，如but for, but that, without, in case of, under,under more favorable condition等。
(4)将条件隐含在名词短语中。
A true friend wouldnot have betrayed me. (=If he had been atrue friend, he would…)
(5)将条件隐含在某些连词(如or, or else, otherwise等)中。用法如下：它们后的句子如果说的不是客观事实，它们前边的句子采用陈述语气，后边的句子采用虚拟语气。
(a)句子(一般现在时)+ or, or else, otherwise + 句子(谓语部分：should\would\could\might等+ 动词原形)
Don’t bother toread all these papers. It would take too long.
(=…If you read all these papers, it would taketoo long)
常用来表示含蓄虚拟条件的手段连词如：so that, unless, in case, supposing, lest,provided，for fear that, oncondition that, if only等。
(注：lest, for fear that和in case引起的从句中谓语动词多用should+动词原形，但可以不用虚拟语气，而用动词的陈述语气形式。)
注意：but后面转折成真实情况的用法
例：I would have bought it yesterday, but I had nomoney.
