虚拟语气分三种情况来掌握
虚拟语气分三种情况来掌握:1、虚拟条件句。
2、名词性虚拟语气。
3、虚拟语气的其他用语。
一、虚拟条件句:条件状语从句是非真实情况,在这种情况下要用虚拟语气。
1、条件从句与现在事实不一致,其句型为:If 主语+过去时,主语+should(could, would,或might)+动词原形,如:If I were you, I wouldstudyhard.If it rained, I wouldnot be here now.2、条件从句与过去事实不一致,句型为:If 主语+had+过去分词,主语+should(could, would,或might)+have+过去分词,如:If the doctor had come last night, the boy wouldhave saved.If I had not studie d hard, I wouldhave failed in the exam last term.3、条件从句与将来事实不一致,句型为:+do,主语+should(could…)+原形do过去时(与现在事实条件句一样)。
If it should rain tomorr ow, we wouldstay at home.If I were to go to the moon one day, I couldsee it with my own eyes.If you missed the film to night, you wouldfeel sorry.注意问题:1、If条件句中绝对不可出现“would”。
2、根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都是遵守上述句型。
3、在条件句中如果出现we re, had, should可省去if,将主语与这些词倒装,例如:Had the doctor come last night, the boy wouldhave saved.Were I to go to the moon one day, I wouldsee it with my own eyes.Should it rain tomorr ow, we wouldstay at home.二、名词性虚拟语气:在表示命令、建议要求、惊叹时的名词性从句中需用虚拟语气,基本句型:主语+(should)+动词原形,如:Mother insist ed that John go to bed at 9 o’clock.(宾语从句)We sugges ted that the meetin g should not be held.It was requir ed that the cropsshould be harves ted at once.(主语从句)The sugges tionthat he be invite d was reject ed.(同位语从句)That is theirdemand that theirwagesbe increa sed.(表语从句)注意:在这种句子中绝不出现“would”“must”“could”等。

虚拟语气的基本句型,即是这If I had got up early, I wouldn’t have been late.If I were to do it, I should do it at once.【说明】①在非正式英语中,条件从句中的第一、第三人称单数主语后可用was代替were。

If I had had enough time, I might have done it better.④条件从句中的谓语动词含有were,had,should时,可以省略从属连接词if,然后采用倒装结构,把were,had,should移到主语前面。
Should you pass this way, do drop in for a visit.= If you should pass this way,……Had I known it, I wouldn’t had made such a silly mistake.= If I had known it,……Were it left to me to decide whether I should have a job immediately or go on to study at college, I wouldn’t hesitate a moment to choose the latter.= If it were left to me to decide……..⑤在同一个句子中不能一部分表示真实条件,另一部分表示非真实条件。

虚拟语气的用法与句型
虚拟语气的用法与句型虚拟语气是指在句子中表达一种假设、愿望、建议、命令等非真实情况的语气。
它在表达的内容上与现实相悖,用于描述与实际情况相反或与现在事实相反的假想情况。
虚拟语气在汉语中分为虚拟条件和虚拟假设两种情况。
本文将详细介绍虚拟语气的用法和常见句型。
一、表示假设的虚拟条件句型1. 如果引导的条件句条件句使用“如果+主语+动词”的结构,表示与实际情况相反的假设。
举例:如果我会飞,我就飞到天空中。
如果你能去,我们就一起去旅行。
如果明天下雨,我就不去跑步了。
2. 要是引导的条件句条件句使用“要是+主语+动词”的结构,表示与实际情况相反的假设。
举例:要是你在这里,我就不会感到孤单。
要是他努力学习,他就可以考上大学。
要是明天放假,我就会去看电影。
3. 假如引导的条件句条件句使用“假如+主语+动词”的结构,表示与实际情况相反的假设。
举例:假如我是你,我就不会这样选择。
假如我有足够的时间,我就会旅行。
假如天气好,我们就可以去海边玩。
二、表示愿望的虚拟条件句型1. 祈使句+“但愿(希望)”句型使用祈使句来表达对未来情况的愿望,后接“但愿(希望)”引导的句子,表示非真实情况的愿望。
举例:多带雨伞,但愿今天不下雨。

努力学习,但愿能考好成绩。
2. 希望/愿望+“(能)+动词原形”使用希望或愿望来表达对未来情况的期望,后接能否+动词原形,表示非真实情况的愿望。

上班迟到是不对的,你应该注意时间。
2. 要是/如果+动词过去式使用要是或如果来引导一个非真实情况的条件句,表示一种建议或建议的情感色彩。
虚拟语气
虚拟语气1. without1)当表示“若没有”时,如果谈论的是一种与事实相反的假设,要用虚拟语气,此时,和but for用法相同:Eg. Life would be quiter without the telephone.2)如果without谈论的只是一种普通的假设,并不强调与既定事实相反,则不必用虚拟语气:Eg. Can you see without your glasses. 如果不戴眼镜,你能看见吗?3)if it weren’t for与if it hadn’t been for这两个也是常见的虚拟句型,表示“若不是有,要不是有”,与but for和without同义:Eg. If it wasn’t for the children, we wouldn’t have anything to talk about.Were it not for this misfortune, he might never have been forced into the business of grinding out novels to support his family. 如果不是因为这一不幸变故,他可能永远不会被迫从事创作小说养家糊口。
注:一般,if it weren’t for用于谈论现在的情况,if it hadn’t been for用于谈论过去的情况,但有时if it weren’t for也可用于谈论过去的情况。
2. 常见的介词短语:in the absence of(如果没有),were it not for(要是没有),but that (假设……不)等:Eg. In the absence of gravitity, there would be no air around the earth.3. 虚拟语气用在would rather,had rather,would sooner(宁愿,宁可),had better,had best (最好),would have句型中,后面如果是动词,后接原形动词。
虚拟语气讲义(15个句式)

虚拟语气用法总结
虚拟语气用法总结虚拟语气分三种情况来掌握:1、虚拟条件句。
2、名词性虚拟语气。
3、虚拟语气的其他用语。
一、虚拟条件句:条件状语从句是非真实情况,在这种情况下要用虚拟语气。
1、条件从句与现在事实不一致,其句型为:If 主语+过去时,主语+should (could, would, 或might)+动词原形,如:If I were you, I would study hard.If it rained, I would not be here now.2、条件从句与过去事实不一致,句型为:If 主语+had+过去分词,主语+should(could, would, 或might)+have+过去分词,如:If the doctor had come last night, the boy would have saved.If I had not studied hard, I would have failed in the exam last term.3、条件从句与将来事实不一致,句型为:If主语+should/wereto+do,主语+should(could…)+原形do,如:If it should rain tomorrow, we would stay at home.If I were to go to the moon one day, I could see it with my own eyes.If you missed the film to night, you would feel sorry.注意问题:1、If条件句中绝对不可出现“would”。
2、根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都是遵守上述句型。
3、在条件句中如果出现were, had, should可省去if,将主语与这些词倒装,例如:Had the doctor come last night, the boy would have saved.Were I to go to the moon one day, I would see it with my own eyes.Should it rain tomorrow, we would stay at home.二、名词性虚拟语气:在表示命令、建议要求、惊叹时的名词性从句中需用虚拟语气,基本句型:主语+(should)+动词原形,如:Mother insisted that John go to b ed at 9 o’clock.(宾语从句)We suggested that the meeting should not be held.It was required that the crops should be harvested at once.(主语从句)The suggestion that he be invited was rejected.(同位语从句)That is their demand that their wages be increased.(表语从句)注意:在这种句子中绝不出现“would”“must”“could”等。
虚拟语气
虚拟语气句型 1 (与现在事实相反)在条件句中用虚拟语气是表示对现在情况的假设,是一种非真实条件句。
句型:If +主语did (were)…,主语would do …主句中除了would之外,还可用情态动词could, might, should.If I were you, I would (could, might, should) help him.虚拟语气句型 2 (与过去事实相反)句型2是对过去情况的假设,表示与过去事实相反的条件和结果。
句型:If 主语 had done,主语 +would have done虚拟语气句型 3 (与将来事实相反)句型3是对将来情况的假设,表示与将来事实相反或可能相反的条件和结果。
句型:If +主语were to / should + 动词原形…,主语woulddo…虚拟语气句型 4 (错综时间虚拟条件句)有时条件从句和主句所表示的动作在时间上可以不一致(例如一个与过去事实相反,另一个与现在事实相反),这种虚拟条件句就称为错综时间虚拟条件句。
在这种条件句中,动词的形式要根据具体情况进行调整。
例句:She would never have behaved like that if she had some common sense.如果她有一些常识的话,她就决不会像那样做了。
If he had listened to me, he would not be in such trouble now.如果他听了我的话,他现在就不会有这样的麻烦。
If I had a bike (now), I would have lent it to you yesterday.假如我有自行车,昨天早就借给你了。
If you had not studied the problem carefully, you would find difficulty now.如果当初你没有认真研究这个问题,现在你就会遇到困难。
