英语虚拟语气
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形式，用来表示说话人所说的话并非是事实，而是一种假设、愿望、疑心或推测。
Ⅰ用以表示虚拟条件的虚拟语气虚拟条件句的三种大体类型:1.与此刻事实相反。
假设与此刻事实相反，条件从句的谓语用过去式(be通经常使用were)，主句谓语用“should (would, could, might)+动词原形”：If you took a taxi，you’d get there quicker. 若是你坐出租车去，你能够快一点到那里。
(但你不坐)If I knew her number I could ring her up. 若是我明白她的号码，我就能够够给她打了。
(可惜我不明白)2.与过去事实相反。
假设与过去事实相反，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.若是我早点起身，我就准时到了。
(但我起身太迟了)If we had found him earlier we could have saved his life. 若是咱们那时早点找到他的话，咱们就能够够救活他。
(可惜咱们找到他太晚了)3.与以后事实相反。
假设与以后事实相反，条件从句的谓语用过去式(be通经常使用were)，主句谓语用“should (would, could, might)+动词原形”：If he went，would you go too? 若是他去，你也去吗?(可能他可不能去) If I asked him，I’m sure he’d help us. 若是我向他提出要求，确信他会帮忙咱们。
(只是我不打算如此做)大多数的虚拟条件句属于上面三种情形的一种，但并非排除存在条件和后果中，一个和此刻情形相反，另一个和过去情形相反，例如：If you had followed what the doctor said, you would not have been so painful now.那个句子在高中显现频率颇高。

虚拟语气的用法与高考必考知识点语气(mood)是一种动词形式，用以表示说话者的意图或态度。
英语中的语气有三种：陈述语气、祈使语气和虚拟语气。
直陈语气(indicative mood),表示所说的话是事实。
祈使语气(imperative mood),表示所说的话是请求或命令。
虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。
一、虚拟语气在条件状语句中的应用条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。
真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。
如：If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。
Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。
虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should／would／might／could +动词原形。
如：If it were not raining, we should go for a picnic. 如果现在不下雨的话，我们就出去野餐了If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。
2. 与过去事实相反的虚拟条件句，条件从句的谓语用had + 过去分词，主句的谓语should ／would／might／could + have ＋过去分词。
如：She would have gone to the party if she had been invited.要是当初她被邀请的话，她就会去参加这次聚会了。
If she hadn't called me, I would have overslept this morning.今天早上，她要是不叫我的话，我就会睡过头了。
3. 与将来事实可能相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were)；should＋动词原形；were to＋动词原形，主句用should／would／might／could +动词原形。
如：If I were to be twenty years old next year, I would take the course of French.明年我要是二十岁，我就会学法语。
If it should fail, I would try again. 要是失败了，我会再试一次。
二、连词if的省略如果虚拟条件句的谓语部分有were，had和should时，可省略if，把were，had和should放到从句主语前面去，多见于书面语。
Had you not helped me，I should have failed. 要是没有你的帮助，我就失败了。
Were you in my position, you would do the same. 假如你处在我的地位，你也会这样干的。
Should they attack us, we’ll wipe them out completely. 假如他们进攻我们，我们就把他们彻底消灭干净。
三、情态动词＋have ＋done的用法1.“could＋have ＋done”是虚拟语气，表示对过去事情的假设，意思是“本来可以／能够做某事而没有做”。
1）He could have passed the exam, but he was too careless. 本来他能够通过考试，但是他太粗心。
2）We could have solved the problem in a more reasonable fashion. 这个问题我们本来是可以更合理得解决的。
3）He could have told her, but he did not choose to.他本来可以告诉她的，但他不愿这样做。
2. “may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测，might的语气比may弱一点。
这种结构主要用于肯定句和否定句，意思是“可能已经”或“也许已经”，疑问句改用can或could。
1）—What has happened to George?—I don't know. He may have got lost.2）They may not have known it beforehand.3）He might have given you more help, even though he was busy.4）She might have achieved greater progress, if you had given her more chances.（5）You might have read about it in the papers.3. “would + have + done”虚拟语气，表示对过去事情的假设，意思是“本来会做”。
1）I would have told you all about the boy's story, but you didn't ask me. 我本来会告诉你这个小男孩的故事，但是你没有问我。
2）Without your help, I wouldn't have achieved so much. 没有你的帮助，我是不会取得如此大的成绩。
3）The victim would have a chance to survive if he had been taken to hospital in time. 4）Had you told me the matter earlier, I would not have done the foolish things. 要是你早点告诉我那件事，我也许就不会做那样的傻事。
4. “should + have + done”意思是“本来应该做某事，而实际没做”。
“shouldn't + have + done”表示本来不应该做某事，而实际做了。
含有指责对方或自责的含意。
1）Tom, you are too lazy. The work should have been finished yesterday. 汤姆，你太懒惰了，这项工作本来应该昨天就做完的。
2）Look, Tom is crying. I shouldn't have been so harsh on him. 看，汤姆哭了，我本来不应该对他如此严厉。
3）You shouldn’t /oughtn’t to have come here alone at such a late hour.你这么晚的时候本不一该一个人来这里的。
（实际是一个人来的）4）You should have come here ten minutes earlier. 你本应该早１０分钟来才是。
5. “ought to+have+done”表示过去应该做而实际并没有做，译成“理应做……”，往往表示遗憾。
与“should+have+done”用法基本一样。
1）I ought to have gone home last Sunday. 我理应上星期日回家。
2）You ought not to have given him more help. 你不应该帮助他那么多。
6. “needn't + have + done”则表示“本来不需要做某事而做了”。
1）I needn't have bought so much wine—only five people came. 我本来没有必要买这么多酒，只来了五个人。
2）I needn’t have borrowed the money yesterday.昨天我根本不需要借钱的。
（实际上已经借了）四、虚拟语气在宾语从句中的应用（1）宾语从句在表示提议、要求、命令、意志等动词后，其谓语用should+动词原形或只用动词原形的虚拟语气，作为suggest，request，demand，propose，advise，insist，require，order，command等动词的宾语。
The doctor suggested that he not go there．医生建议他不要去那里。
He suggested that we should leave early. 他建议我们早点动身。
The judge ordered that the prisoner should be remanded. 法官命令被告还押。
（2）wish的宾语的从句，表示愿望，常省去连词that。
☆表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；be动词统统都用wereI wish I knew everything in the world.I wish that the experiment were a success. I wish it were true．☆表示与过去相反的愿望，从句谓语用“had +过去分词”或“could／would／might／+have+过去分词”How she wished his family had gone with him？I wish you had called yesterday．We wish you had come to our New Year’s party.我们真希望你来参加了新年联欢会。
She wished she had stayed at home. 她后悔的是她当时要是留在家里就好了。
I wish that I could have gone with you last night.☆表示将来没有把握或不太可能实现的愿望，用would (could)＋动词原形。
I wish you would stay a little longer. 我希望你再待一会儿。
I wish you wouldn’t smoke any more.我希望你不再抽烟了。
I wish that he could try again. I wish that someday I should live on the moon.五、虚拟语气在表语从句中的应用名词suggestion，proposal，order，advice，demand等作主语，其后的表语从句中的谓语动词一般使用虚拟语气，用should +动词原形或省略should。
