虚拟语气的错综条件句子
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。
虚拟语气在条件从句中的用法

虚拟语气在条件从句中的用法一、虚拟语气在条件从句中的用法(一)形式注:1.在从句中,be动词多用were的形式。
在口语中,如果主语是第一、第三人称单数的话,be动词可用was,但人们总是说:If I were you...2.主句中的谓语可以由would,should,could和might这四个不同的情态动词来构成。
3.与将来事实相反的条件从句中,谓语有三种不同的形式:过去式、were +to do或should +do。
例句1:If I were you,I would study hard.我要是你的话,我就会好好学习。
(与现在事实相反)例句2:If I had studied hard,I would have passed CET-6 last semester.我要是早就好好学习的话,那么我上个学期就通过六级考试了。
(与过去事实相反)例句3:If Iwere to pass CET-6,I would treat you to dinner at KFC.我要是过了六级考试,就请你去吃肯德基。
(与将来事实相反)1/ 9(二)省略/倒装如果在虚拟从句中包含有一个助动词、情态动词、动词be 或have,则可把if省略,把上类动词提到主语之前,使用倒装语序。
例句4:Had it not been for the PLA,we wouldn't have been able to beat the flood.4要不是人民解放军,我们是无法战胜洪水的。
例句5:Were he here now,he would certainly help me.5他要是在这里肯定会帮我的忙。
注4:例句4中的从句部分出现了否定词not,如果把该句还原成正常语序,应该是:If it hadn't been for the PLA,we wouldn't have been able to beat the flood.但是一旦句子发生了省略,就必须把hadn't分开,否定词not还原,放在主语之后,不可写成Hadn't it been for的形式。
虚拟语气和错综条件时间从句区别

虚拟语气和错综条件时间从句区别You would be much better now if you had taken my advice.(错综时间条件从句)You would have been much better now if you had taken my advice.(虚拟)假若你当时听我的话,你现在就会好多了在表示虚拟语气的句子中,条件从句表示的动作与主句表示的动作发生的时间并不一致,这时,谓语动词的形式要根据各自所表示的时间来调整,这种现象叫做错综时间虚拟语气。
You would be much better now if you had taken my advice.假若你当时听我的话,现在就会好多了。
(从句过去,主句现在)would have been是与过去事实相反的非真实条件句一般来说虚拟语气中的混合时态的句子都有具体的时间词来进行提示的,比如说:If we had arrived at the shopping mall earlier, we would get more gifts now.如果我们早点来商场的话(过去的时间虚拟),我们现在就可以拿更多的礼物了(现在的虚拟)。
这是两个不同时间的虚拟语气,有相应的时间词来提示的,now来提示后句的时间是现在而不是和前面一样的过去。
If we had arrived at the shopping mall earlier, we would have got more gifts.如果我们早点来商场的话,我们就会拿到更多的礼物了。
(已经拿了礼物了,但是实际上过去拿的时候没有拿到那么多)如果从句和主句都表示过去的,那从句用had done,主句用would ,could,might,should+have done如:Ifyouhadtakenmyadvice,youwouldnothavebeenlateforthemeetingyesterday.如果从句表示过去的,但主句表示现在的,从句用haddone,主句用would,could,might,should+do,如:Ifyouhadtakenmyadvice,youwouldnotbe late forthe meeting now.这种一般都有个时间,如果没有表示时间的词也可以从上下文看出。
5组虚拟语气

*It’s high time we stopped / should stop cutting down the trees.
lest 在lest引导的目的状语从句中,谓语动词用(should )+ 动词原型 *She didn’t allow her sister go out lest she (should ) catch flu. in case 万一,以防,后面接现在时,或者should +动词原型 *I always take an umbrella in case it rains.
,重要,惊异,失望等形容词或者过去分词后 容词/ 过去分词+that 句型 mazing/ surprising /odd/ strange/ wrong/a pity/ a shame/ incredib hould 不可以省略 good that the children here should be given so much homework ocked that she should have said such a thing to you.
4. 跳层虚拟句(即句子一半为虚拟,另一半为陈述语气; but/前句用虚拟而or/otherwise后句用虚拟) 4. 跳层虚拟句(即句子一半为虚拟,另一半为陈 . 述语气;but/前句用虚拟而or/otherwise后句用虚 拟) *He would put on weight, but he doesn’t eat much. 与现在事实相反 *He would have put on weight, but he didn’t eat much. 与过去事实相反 or, or else, otherwise *I forget where I read the article, or I would show it to you now. 与现在相反 *Mary couldn’t have received my letter, otherwise she would have replied before now. 与过去相反 but / except+ 表示条件 * would have gone with her but / except I was ill.
高中英语语法-虚拟语气全总结

①错综时间条件句: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,被称为错综时间条件句,动词的形式要根据它表示的时间作出相应的调整。
如:If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首,变成倒装句式。
如:If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的时机,我会更加努力学习。
If you had e earlier, you would catch the bus.→Had you e earlier, you would catch the bus.如果你来得早点,你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话,我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如:What would you do with a million dollars" (=if you had a million dollars)如果你有100万元,你会做什么?We couldn’t have finished the work ahead of time without your help. (=if we hadn’t got your help)没有你的帮助,我们不可能提前完成这项工作。
虚拟语气的几种用法

虚拟语气的几种用法1.错综时间条件句虚拟语气通常用于含条件状语从句的主从复合句中。
条件状语从句中表示与现在、过去或将来事实相反的虚拟语气比较容易掌握,但绝不可把它们当作一成不变的数学公式一样对待。
就是说,不能只单纯背语法条条框框,而应充分理解句子锁定的语言环境。
有时从句动作与主句动作发生的时间不一致。
这时就要根据各自表示的时间概念加以调整。
如:If he had taken my advice, he would be much betternow.(从句与过去事实相反,主句与现在事实相反。
)2.含蓄条件句有时假设的情况并不是以条件状语从句的形式表示出来,而是通过一个介词(如:without; butfor)引出的短语,一个连词(如:but; or; otherwise)引出的从句或其它方式来表示。
如:Without your help, we couldn’t have finished the job intime.(Without your help=If you hadn’t helped us)He could have given you more help, but he was busy.(buthe was busy=if he had not been busy)3.倒装句如从句中有were, had或should,则可以省去if, 并将were,had或should提前到句首,构成部分倒装。
如:Were I to be young again, I would studymedicine.(从句正常语序为:If I were to be young again)Had you not left so early, you might have missed thetrain.(从句正常语序为:If you had not left so early)4.错综语气有时从句用虚拟语气,主句却用陈述语气或祈使语气。
虚拟语气用法总结

虚拟语气用法总结虚拟语气是说话者用来表示假设,或难以实现的情况,而非客观存在的事实。
学习虚拟语气,我们需要注意以下几个要点:一、虚拟语气在带有条件状语从句的复合句中的构成和用法。
根据不同的时间,主、从句中动词形式如下表:If we left now, we would arrive in good time. 如果我们现在就走的话,我们就会及时到达。
They would have come to your party if they had had time. 如果他们有时间就会参加你的聚会。
If you lived there for a while, you’d change your mind about the place. 如果你在那儿住上一段时间,你就会改变对那地方的看法。
这里我们需要注意以下三点:1. 错综时间条件句有时条件状语从句中的动作和主句中的动作发生的时间不一致,这时动词的形式要根据它所表示的时间加以调整。
如:If you had listened to the doctor, you would be all right now. 如果你当初听了医生的话,身体现在就好了。
2. 虚拟条件句的倒装形式如果虚拟条件从句中有were, had或should时,可以把if省略,而把这几个词放到主语之前,构成倒装句。
如:Were I you, I wouldn’t go there alone. 如果我是你,我不会一个人去那儿的。
Had he worked harder, he would have got through the exam. 如果他学习再努力点的话,他就会通过考试。
Should you be fired, your health care and other benefits will not be immediately cut off. 如果你被解雇,你的医疗保险和其他权益并不会立即中断。
(完整版)虚拟语气的错综条件句子

虚拟语气的错综条件句子,也就是常说的混合条件句,即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。
)混合虚拟语气有时主句和从句的谓语动词指不同的时间,这时需要用混合虚拟语气。
一般来说,在这种情况下,主从句谓语动词指代的时间不同,所以我们又可以错综时间条件句,在这种虚拟情况,动词形式应根据实际情况灵活使用,在做这些题目时候尤其要注意每道题目的提示语:时间状语。
绝大多数情况下,从句或者主句都有相关的时间状语,这是解题的关键。

Many dead would now be alive if they have not attempted to return for something. Many dead would now be alive if they have not attempted to return for something. Had Paul received six more votes in the last election, he would be our chairman now.混合虚拟语气还有一种情况就是事实和虚拟假设的混合句,这样的句子不仅仅是时间的不同,而重要是事实和假设的混合。

混合虚拟语气
有时主句和从句的谓语动词指不同的时间,这时需要用混合虚拟语气。
一般来说,在这种情况下,主从句谓语动词指代的时间不同,所以我们又可以错综时间条件句,在这种虚拟情况,动词形式应根据实际情况灵活使用,在做这些题目时候尤其要注意每道题目的提示语:时间
状语。
绝大多数情况下,从句或者主句都有相关的时间状语,这是解题的关键。

I would have gone to visit him in the hospital had it been at all possible, but I was fully occupied the whole of last week.n the hospital had it been at all possible, but I was fully occupied the whole of last week.该句前半部分是假设虚拟,而后半部分是事实的陈述。
Your math instructor would have been happy to give you a make-up examination had you gone and explained that your parents were ill at the time. e time.该句前半句用的是假设虚拟,后半句主句也用的是假设虚拟(如果你去并且解释的话),但是后半句的从句用的是事实语气,因为“父母病了”是客观事实,故不需要用虚拟形式had been。
