最基本的虚拟语气句型
: 最基本的虚拟语气句型:1. 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might +动词原形。
If places were alike, there would be little need for geographers.如果各个地方都一样,就不需要地理学家了。
2. 虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had+过去分词,主句用would / should / could / might + have +过去分词。
If he had known your address yesterday,he would have telephoned you.3. 虚拟将来时是表示对将来实现的可能性很小的或不确定的假设。
If从句的谓语形式用一般过去式或用were to / should +动词原形,主句用would / should/could/ might +动词原形。
If he were to leave today, he would get there by Friday4.省略if 采用倒装语序的条件句。
有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if省去,而将had , should, were等词提到主语之前,即用倒装结构。
If he had worked harder, he would have got through the exams.==>Had he worked harder, he would have got through the exams.If he were to leave today, he would get there by Friday.==>Were he to leave today, he would get there by Friday.If I were in your place, I wouldn’t do that.==>Were I in your place, I wouldn’t do that.5. 有时虚拟条件句并没用if 从句表示出来,而是用介词短语(otherwise, or, without, but for)、上下文或其它方式来表示。
什么是虚拟语气
什么是虚拟语气?虚拟语气(Subjunctive Mood)是英语中一种用来表达假设、愿望、建议、要求等非真实情况的语气。
与陈述语气不同,虚拟语气用于表达与事实相反或与现实不一致的情况。
虚拟语气常见于条件句、表达愿望的句子和建议命令等语境中。
虚拟语气的使用有以下几个方面:1. 条件句中的虚拟语气:- If I were rich, I would travel around the world.(如果我富有,我会周游世界。
)- If he had studied harder, he would have passed the exam.(如果他学习更努力,他就会通过考试。
)在虚拟语气的条件句中,谓语动词的过去式常用于表示与现实相反的假设情况。
对于"be"动词,无论主语是什么,都使用"were"。
2. 表达愿望和建议的虚拟语气:- I wish I were taller.(我希望我更高。
)- It's important that she study for the test.(她应该为考试学习很重要。
)在表达愿望和建议时,虚拟语气常用于动词的基本形式,而不是现实情况下的时态形式。
3. 命令和要求的虚拟语气:- I insist that he be here on time.(我坚持要求他准时到达。
)- It is essential that they submit the report by Friday.(他们必须在星期五之前提交报告。
)当我们使用虚拟语气来表达命令和要求时,谓语动词常用于动词的基本形式,并使用"that"引导从句。
虚拟语气在英语中的使用非常灵活,可以用于不同的语境和句型中。
掌握虚拟语气的使用可以帮助我们准确地表达假设、愿望、建议和要求等非真实情况,从而提升英语表达的准确性和表达能力。
英语语法:三个常考虚拟语气句型
英语语法:三个常考虚拟语气句型一、句型介绍这两个句型是If it weren’t for…和If it hadn’t been for…,这是两个很常用的虚拟语气句型,也经常受到命题人的青睐,其意为“若不是(有)”“要不是有”。
如:If it weren’t for water, no plant could grow. 要是没有水植物就无法生长。
You wouldn’t be anywhere if it weren’t for Ruth. 若不是有鲁思你不会有任何成就。
If it hadn’t been for the doctor, he would have died.要不是医生救了他,他就会死了。
If it hadn’t been for Mary, I might not have understood. 要不是有玛丽,我可能还不理解。
二、与but for, without等替换这两个句型有时可用but for, without等替换。
如:要不是有你帮忙,我们是不会成功的。
If it hadn’t been for your assistance we wouldn’t have succeeded.=But for your assistance we wouldn’t have succeeded.=Without your assistance we wouldn’t have succeeded.三、时间上的同与异原则上说,if it weren’t [wasn’t] for 用于谈论现在的情况,而if it hadn’t been for 用于谈论过去的情况。
但实际上if it weren’t [wasn’t] for有时也可用于谈论过去的情况:If it weren’t for their help, we couldn’t have got over the difficulties. 要不是他们协助,这些困难我们是克服不了的。
虚拟语气句型
常用虚拟语气句型1.if条件句条件状语从句可分为真实条件句,即条件满足,事实就发生的情况;和非真实条件句,即与事实相反或难以实现的假设情况。
虚拟语气的基本句型,即是这种非真实条件状语从句。
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 was you, I would accept the invitation.②主句中的would可用于各种人称,而should只用于第一人称。
③在主句中也可用情态动词could,might代替would,should。
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。
