英语语法 虚拟语气的知识点归纳
英语语法虚拟语气的知识点归纳一、虚拟条件句(一)含有if条件句的主从句的虚拟语气总结:1. If 条件句中谓语动词的虚拟结构是在原来陈述语气所用时态的基础上倒退一个时态(对将来虚拟的were to do/should do例外)2. 主句要借助于情态动词的过去式,后跟动词原形(现在或将来)或have done(过去);if条件句中只出现一个情态动词,即对将来虚拟的should.3.做此类题目时一定要分清是从句还是主句谓语动词的虚拟,还要把握好时态。
注意:1. 在虚拟条件从句中,动词“be”的过去时态一律用”were”,不用was。
2. 在虚拟条件状语中如果有were, should, had这三个词中任何一个,可省略if,把这三个词提到主语之前, 变成:were/should/had +主语+剩余成分。
3.在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。
如我们可说Were I not to do., 而不能说Weren‘t I to do。
4.在表示与将来事实相反的条件句中,只能用should,而不能用would,could和might 等。
5.主句中的should通常用于第一人称,would,could以及might 可以用于各种人称eg :①If I were a bird, I could fly in the air.如果我是一只小鸟,我就能在空中飞行。
②I wish I could pass the examination.我希望我能通过考试。
在虚拟条件句中,对于与将来事实相反的情形,请注意以下几点:(1)条件从句表示的内容与将来事实相反,实为对将来情况的推测,用过去时表示虚拟;(2)条件从句谓语除用过去式外,有时也用“should+动词原形(表示可能性极小,常译为“万一”)”或“were to+动词原形(表示与将来事实相反的假设)”;(3)条件从句使用“should+动词原形”这样的谓语形式时,主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气形式外,也可用直陈语气或祈使语气。

它表达的是建议、不满、怀疑、忧虑、推测、假设、想象、祝愿等。
2.虚拟语气用于非真实条件句英语中的条件句有两种:真实条件句和非真实条件句。
真实条件句实现的可能性非常大,常用if, unless, as long as, so long as, once等引导,谓语动词常用陈述语气;非真实条件句常表示不能实现或纯假象的情况,谓语动词要用虚拟语气。
非真实条件句包括虚拟条件句、推测条件句、错综时间条件句。
①虚拟条件句、推测条件句虚拟条件句可分为两类:一类是叙述与现在事实相反的情况,一类是叙述与过去事实相反的情况。
另外,还有一类用于推测将来的情况,也称作推测条件句。
从句中提出一种与客观现实不相符或根本不可能存在的条件,主句会产生一种不可能获得的结果。
句中的虚拟语气根据不同的时间有3种不同的形式:I would lend him the money if he asked me.他要是问我,我愿意借钱给他。
(意愿)If he had time, he should do it.要是有时间,他愿意做那件事。
(意愿)He could move the big stone if he should try.努力的话,他能搬动那块大石头。
(能力)If he forgot to come, you could go instead.他要是忘了没来,你可要替他来。
(许诺)A.与现在事实相反If I had enough money, I would buy a computer.如果我有足够的钱,我将买一台电脑。

It it weren’t for your help, we would be in serious trouble.若不是你帮忙,我们会遇到大麻烦。

虚拟语气在非真实条件句中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。
否定句时not留在原来位置不变。
如:If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会,我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come 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。
Without your help, we couldn’t have finished the work ahead of time.= But for your help, …= If it had not been for your help, …= Had it not been for you help, …没有你的帮助,我们不可能提前完成这项工作。
④含蓄条件句有时在虚拟语气中并不总是出现if引导的条件句,而是通过其他手段来代替条件句。
如:I was ill that day. Otherwise, I would have taken part in the sports meeting. (副词)He telephoned to inform me of your birthday, or I would have known nothing about it. (连词)A man who stopped drinking water would be dead in about seven days. (定语从句)I might have given you more help, but I was too busy. (连词)Everything taken into consideration, they would have raised their output quickly. (独立主格结构) ⑤even if, even though也可用于虚拟语气,其形式与if 从句在虚拟语气中的形式相同。
