Were I to do the job, I would finish doing it within two weeks.Had it not been for his help, we couldnt have arrived there on time.Should it rain tomorrow, I would stay at home.3. wish后宾语从句中的谓语构成动词wish后的宾语从句表示未实现的或不行能实现的愿望，其宾语从句中的谓语动词要用虚拟语气，有以下三种构成形式。
大学英语语法精讲【重点、考点全涵盖】
语法部分第一讲虚拟语气I. 考点分析：虚拟语气是动词的特殊形式，用来表达说话人的意愿、建议、请求、意图、惊奇、设想等未能或不可能成为事实的情况，以及在说话人看来实现的可能性很小的情况。
虚拟语气是非常重要的语法考点。
考察历届四级试题，我们发现与虚拟语气有关的考题每次至少2题，有时甚至3-4题。
虚拟语气的考查要点有：1. 虚拟语气的形式：分清虚拟时间和主句、从句所使用的动词形式十分重要，因此我2. 要注意从句中第一/三人称的过去式was用were代替。
例如：If I were invited, I would come.If she were not ill, she could do a lot of things.3. if条件句中如谓语动词是were, had, should, could时，可以省略if, 把它们前置。
例如：Had my father a lot of money, he would send me abroad.Could I do it, I would surely do it.Should the Black Death reappear, what should we do?（万一黑死病再次出现，我们该怎么办？）4. 错综时间的条件句是难点，如99年1月第60题: If I hadn’t stood under the ladder to catch you when you fell, you wouldn’t be smiling now.（从句用过去完成时，主句用现在进行时）又如：If I were you, I would have gone to the film last night.(从句虚拟现在，主句虚拟过去)；If we hadn’t got everything ready by now, we should be having a terrible time tomorrow.(从句虚拟过去，主句虚拟将来)；If the weather had been more favorable, the crops would be growing still better.(从句虚拟过去，主句虚拟现在)5. 虚拟句的另一难点是省略if条件句的含蓄条件句，如：I would have written the paper before, but I have been ill.(=If I had not been ill, I would have written the paper before.);A true friend would have acted differently. (=A friend, if he had been true, would have acted differently.)6. 注意介词短语without, but for, in the absence等表示虚拟条件。
大学英语六级虚拟语气例题解析
大学英语六级虚拟语气例题解析大学英语六级虚拟语气例题解析汇总大学英语六级虚拟语气例题解析(一)1、Jean Wagner’s most enduring contribution to the study of Afro-American poetry is his insistence that it in a religious, as well as worldly, frame of reference.A. is to be analyzedB. has been analyzedC. be analyzedD. should have been analyzed解析：(C)在表示要求、愿望、建议、请求、命令等含义的名词同位语从句中，从句谓语动词要用虚拟语气形式，即should(可以省略)+动词原形。
2、 I would have gone to visit him in the hospital had it been at all possible, but I ______ fully occupied the whole of last week.A. wereB. had beenC. have beenD. was解析：(D)本道题目的前半句话是对过去情况的一种假设，但事实上并没有发生，而事实上没有发生的真实原因是句子的后半部分由but 引导的转折句所表述的真实。
因而but所引导的句子中应该用表示志过去事实相符合的表陈述的时态，即一般过去时。
3. I apologize if I you, but I assure you it was unintentional.A. offendB. had offendedC. should have offendedD. might have offended解析：(B)此题要求在if从句中选择适当的动词形式，以主句中的动词apologize(抱歉)来看，if从句中表达的内容应该是过去做的事，因此可以排除(A)，因为(A)是现在时。
(完整版)虚拟语气详解
虚拟语气详解虚拟语气表示说话人的主观愿望（往往与客观事实相反），或是表示假象和猜测。
虚拟语气无论从形式上还是时态上都比较复杂，需要归类记忆。
虚拟语气大体分为三类：(1) be型虚拟(2) were型虚拟(3) if 条件句及主句虚拟下面会详细说每种虚拟形式的特征和规律，考试时先判断属于哪种虚拟类型，剩下的皆是套路~（1）be型虚拟（基本是套路）形式：should + 动词原形，should可以省略用法：1）表示“命令、建议、要求”等意义词语之后的宾语从句用be型虚拟，常见的词如下: demand, desire, insist, order, ask, command, propose, recommend, suggest, prefer, require, request等最常见的形式是这类动词后面接着一个宾语从句，则宾语从句的谓语部分要用（should）+ 动词原形来虚拟例: We demand that the meeting（should）be postponed.The manager suggested that we (should) work together.注意：有时候你所见到不一定是上述动词引导的宾语从句，而是由上述词变体后所引导主语从句(it做形式主语，如：it is advised/ suggested/ requested/ ordered/ proposed that…)、表语从句或同位语从句例如：It is required that the students (should) learn a foreign language. (主语从句) The requirement is that all the equipment in the meeting room (should) be checked twice before. (表语从句)We didn’t stand for his proposal that the meeting (should)be postponed. (同位语从句)只要看到句中有上述动词或其变体，不管词性怎么变、句型怎么变，都用be型虚拟！特例：suggest和insist这两个比较特殊，当suggest作“暗示、表明、说明”讲，insist作“坚持说”讲，后面一般跟的是客观事实，不需要虚拟~这是一个比较重要的考点，体会下面两组句子：We all suggest that a lab (should) be built. 我们都建议建一个实验室。

2 语气的种类⑴ 陈述语气：表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。
如：①There are two sides to every question.每个问题都有两个方面。
②Were you busy all day yesterday?昨天一整天你都很忙吗?③How good a teacher she is!她是多好的一位老师啊!⑵祈使语气：表示说话人对对方的请求或命令。

• B。Should you be fired是由If you should be fired变来的，又如：Should you require (=If you should require) anything give me a ring.如 果需要什么，可以给我打电话。
4. 连词if的省略。 在书面语中，条件从句可以不用连词if, 而将谓语中 的过去式were, had或should等移至主语之前。如： Had I time, I would come. Were you in my position, you would do the same. Should they attack us, we’ll wipe them out completely.
“Mary looks hot and dry” “So _________ you if you had a high fever.” A. do B. are C. will D. would
D。那是因为其后的 if条件状语从句的谓语用 的是虚拟语气（许多同学会忽略此信息）， 所以主句要用 would而不用 will。
Yesterday, Jane walked away from the discussion. Otherwise, she ________ something she would regret later. A. had said B. said C. might say D. might have said
—Don’t you think it necessary that he ________ to Miami but to New York? — I agree, but the problem is ________ he has refused to. A. will not be sent; that B. not be sent; that C. should not be sent; what D. should not send; what

英语虚拟语气讲解
虚拟语气虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。
虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。
Ⅰ用以表示虚拟条件的虚拟语气虚拟条件句的三种基本类型:1.与现在事实相反。
若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”：If you took a taxi，you’d get there quicker.如果你坐出租车去，你可以快一点到那里。
(但你不坐)If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。
(可惜我不知道)2.与过去事实相反。
若与过去事实相反，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”：If I’d left sooner，I’d have been on time.要是我早点动身，我就准时到了。
(但我动身太迟了)If we had 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。
(可惜我们找到他太晚了)3.与将来事实相反。
若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”：If he went，would you go too? 如果他去，你也去吗?(大概他不会去)If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。
(不过我不打算这样做)大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和后果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高。

英语的虚拟语气知识点讲解
英语的虚拟语气知识点讲解一、虚拟语气的概念。
虚拟语气是一种特殊的动词形式，表示所说的话不是事实，而是一种假设、愿望、怀疑、推测或与事实相反的情况等。
二、虚拟语气在非真实条件句中的用法。
1. 与现在事实相反。
- 条件从句的谓语动词用一般过去式（be动词一般用were），主句的谓语动词用“should/would/could/might + 动词原形”。
- 例如：If I were you, I would take an umbrella.（实际上我不是你）2. 与过去事实相反。
- 条件从句的谓语动词用“had + 过去分词”，主句的谓语动词用“should/would/could/might+have +过去分词”。
- 例如：If he had taken my advice, he would have passed the exam.（实际上他没听我的建议，也没通过考试）3. 与将来事实相反。
- 条件从句的谓语动词有三种形式：一般过去式、“should+动词原形”、“were to+动词原形”，主句的谓语动词用“should/would/could/might +动词原形”。
- 例如：If it rained/were to rain/should rain tomorrow, we would not go out.三、虚拟语气在宾语从句中的用法。

英语虚拟语气知识点总结
英语虚拟语气知识点总结英语虚拟语气知识11、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。
虚拟语气
2.虚拟语气9．1 虚拟语气概说虚拟语气是英语学习中的一个难点，也是大学英语四级考试及其它各种考试的一个考点。
因此，我们应该熟练掌握虚拟语气的各种形式，较好地把握虚拟语气的用法。
虚拟语气是一种特殊的动词形式，用来表示说话人表达的不是事实，而是一种与实际事实相反的假设、愿望、怀疑或者主观的设想以及没有把握的建议等。
虚拟语气主要用在条件句中。
9. 2 虚拟语气在一般条件句中的应用9．2．1 与现在事实相反的假设这种虚拟语气表示一种在现实事实中并不存在的假设情况，其主句、从句谓语动词的表现形式如下表。
例 1 If I were you, I would not go out with him. 假如我是你，我不会跟他出去。
例 2 Y ou wouldn‟t be so sleepy in the morning if you went to bed earlier.假如你早点睡觉的话，早上就不会打瞌睡。
例 3 If I had time, I would certainly go. 如果我有时间，我一定去。
例 4 If John were here, we could play tennis. 要是约翰现在在这儿，我们就能打网球。
例 5 If Mary weren‟t always ready to help, I would not ask her to look after the ch ildrenwhile I was away.如果玛丽不是一向乐于助人的话，我外出的时候就不会请她帮我照看孩子们的。
9．2．2 与过去事实相反的假设这种虚拟语气表示过去实际上没有发生过的事情，其谓语动词的时态要用过去完成式表示过去时。
主句、从句的谓语动词的表现形式如下表。
例 1 If we had known that she had planned to arrive today, we could have met her atthe bus station. 当时我们要是知道她计划今天到，我们就会到汽车站去接她。
大学英语语法-虚拟语气
虚拟语气1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。
(事实上是不知道)2. He wishes he hadn't lost the chance.他真希望没有失去机会。
(其实已失去)3. You wished she would arrive the next day.(would + arrive)你希望她第二天会到。
(事实上她还没到)Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。
它仅有两个形式，即be型虚拟式和were型虚拟式。
Be型虚拟]-----be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。
其主要用法如下：1)用于表命令、决定、建议、坚持等词语之后的that分句中这一用法又分三种情况：a)用在decide,decree,demand,insist,move,order,prefer,propose,recommend,request,req uire,suggest,vote等动词之后的that分句中.（宾语从句）在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。
He ordered that all the books be sent at once.He ordered that all the books be sent at once.we propose that somebody neutral take the chair.She insisted that she go to the south for her holiday.b)用在advisable,appropriate,desirable,essential,fitting,imperative,important,impossibl e,necessary,obligatory,proper等形容词之后的that分句中。
