虚拟语气的用法虚拟语气表示一种假设的情况,或一种主观的愿望,即动词所表示的动作或状态并非事实,或不可能实现。
英语虚拟语气的形式有下列几种:一、虚拟语气用于条件状语从句注意:主句中的should通常用于第一人称,would 可用于任何人称,同时也可根据意思用情态动词could, might等代替should, would。
1.与现在事实相反条件从句结果从句连接词2.3.错综时间虚拟语气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,动词的形式要根据它所表示的时间来调整。
例如:If I were you, I would have gone home.(从句说的是现在,主句指的是过去。
)If you had followed the doctor's advice, you would be quite all right now.(从句说的是过去,主句指的是现在。
)If the weather had been more favorable, the crops would be growing still better.其它状语从句1.方式状语as if(as though)如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用"had+过去分词";表示与将来事实相反;谓语动词用"would(might, could)+动词原形"。
unit 1 ArtGrammar虚拟语气Subjunctive Mood教案一:分类1在英语中有三种语气,陈述语气,祈使语气和虚拟语气2 虚拟语气表示说话的人的一种愿望、意见、命令、要求,有时候是一种非真实的假设、料想或者是不可能实现的与事实相反的愿望。
二、形式虚拟语气经常用在if引导的条件状语从句中,在条件句中做出和事实不相符的一种假设。
a.和现在事实相反的假设如:If I were you, I would study hard.If he had enough money, he would buy a puter.b.和过去事实相反的假设如:If you had e five minutes earlier, you would have met him.If they had been treated in time, they would not have died.c.和将来事实相反的假设如:If I were to do it, I would do it in another day.If it rained tom orrow, we wouldn’t be able to go on piic.d.混合条件句混合条件句是指条件句是对过去事实相反的假设,而主句则表示现在的某种情况。
三、注意事项①如果从句中有were、had或者should时,则可以省略if,并将were、had或者should提前至句首,构成部分倒装,但如果是否定句,则否定词not不提前。
如:Were I to be young again, I would study medicine.=If I were to be young again, I would study medicine.Had you not left so early, you might have missed the train.=If you had not left so early, you might have missed the train.②用介词短语代替条件状语从句,常用的介词有with, without, but for.如:Without your help, we couldn’t have finished the work ahead of time.=But for your help, we couldn’t have finished the work ahead of time.=If it had not been for your help, we couldn’t have finished the work ahead of time.=Had it not been for your help, we couldn’t have finished the work ahead of time.③在句中出现了表示转折的连词,如or, or else, otherwise等,如果句意和事实不符也要用虚拟语气。
