英语虚拟语气的三种时态三种时态中的英语虚拟语气虚拟语气(Subjunctive Mood)是英语语法中的一种特殊形式,用来表达与事实相反、与现实不符合或带有假设、建议、命令等语气的情况。
在英语中,虚拟语气可用于过去、现在和将来三种时态。
本文将详细介绍英语虚拟语气在这三种时态中的应用。
一、过去式虚拟语气(Past Subjunctive)过去式虚拟语气用于对过去发生的事情进行虚拟表达。
它通常与“if”或“wish”等引导的从句连用,表示对过去事实的非真实假设或对过去的遗憾、愿望等。
用法如下:1. 与现在事实相反的假设:If I were you, I would apologize.(如果我是你,我会道歉。
)If she had studied harder, she would have passed the exam.(如果她学得更努力,她就能通过考试。
)2. 对过去的遗憾、愿望:I wish I had taken that job.(我希望我当时接受了那份工作。
)He wishes he were taller.(他希望自己更高一些。
)二、现在式虚拟语气(Present Subjunctive)现在式虚拟语气用于对现在或将来的事情进行虚拟表达。
它通常与“if”或“suggest”等引导的从句连用,表示对现实的非真实假设、建议或要求。
用法如下:1. 对现在事实相反的假设:If it were to rain, we would stay at home.(如果下雨的话,我们将呆在家里。
)I suggest that he be more careful.(我建议他更加小心。
)2. 对现在的建议或要求:It is important that she arrive on time.(她准时到达是很重要的。
) They demanded that he pay the bill immediately.(他们要求他立即支付账单。

(3)(钟、表等)走快【典型例句】We gained experience by working during the summer.我们从暑期的工作中获得了经验.Students gain knowledge by reading.学生们通过阅读增加知识。
We gained our destination before dark.我们天黑之前到达了目的地。
My watch gains five minutes a day.我的表一天快五分钟。
2. concentrate vi.&vt.集中(注意力、思想等)集中于某处;使集中于一点【精讲拓展】concentrate on/uponconcentrate one’s attention onconcentration n.【典型例句】We must concentrate our attention on efficiency.我们必须把注意力集中在效率上。
For centuries the population of Europe has been concentrated in large cities.几个世纪以来,欧洲的人口一直集中在大城市里。
It’s hard to concentrate on writing a letter with the TV on.开着电视机很难集中精力写信。
Concentration is essential if you want to do a good job.如果你想把事情做好,专心是必要的。
3. connect vt.&vi.连接;结合;连结,接通电话,(与with连用)有联系,有关搭配:connect with /to;connection n.be connected to/with/by【典型例句】This railway connects London and Edinburgh.这条铁路连接伦敦与爱丁堡。
Unit13虚拟语气专题讲解【知识要点】语气(mood)是一种动词形式,用以表示说话者的意图或态度。
英语有三种语气:*直陈语气(indicative mood)---- 事实France lies to the east of England.*祈使语气(imperative mood)---- 请求、命令Make yourself at home.*虚拟语气(subjunctive mood)If there were no air and water , we should not be able to live on the earth.虚拟语气表示说话人的一种主观愿望或假想,所说的是一个条件而不一定是事实,或与事实相反。
一. 虚拟语气在if条件状语从句中的用法假设类型条件从句谓语动词形式主语谓语动词形式与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形与过去事实相反had + 过去分词should/ would/could /might + have+过去分词与将来事实相反1.should+动词原形2.动词过去式3.were to+动词原形should/ would/ could/ might +动词原形1. 在错综条件句子中,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。
1)If I were you,I wouldn't have missed the film last night.2)If he had followed the doctor's advice,he would recover already.(从句与过去事实相反,主句与现在事实相反。
)2、在if虚拟条件句中,有时可把连词省去,采用倒装语序把谓语动词were或助动词did,had,should 移到句首构成非真实条件从句的另一种句型,其意思不变。
1)Had we time to spare,we would be glad to go to the park.2)Were it not for the discovery of electricity,the modern world would experience great inconvenience.3、有时假设的情况不用if引导虚拟条件从句来表述,而用介词(如without, but for等)引出的短语、分词(如supposing等)引出的短语、并列连词(如or,otherwise,but,though等)、由动词suppose引出的祈使句或通过上下文的意思来表达。
此时句中谓语动词仍采用虚拟语气的相应形式。
1)But for your advice,I would not be able to do this work.2)Victor obviously doesn't know what's happened,otherwise he wouldn't have made such a stupid remark.。
4、通过Were it not for...或Had it not been for...等句式表达条件Were it not for(=If it were not for) the leadership of the Party,we could not live a happy life.Given more attention, the trees could have grown better.与现在事实相反过去时(were)与过去事实相反had+过去分词与将来事实相反would/could/might+动词原形I wish I were as tall as you.He wished he hadn't said that.I wish it would rain tomorrow.三.表示要求,命令,建议的虚拟语气一个(坚持) ___insist______两个(命令) ___order, command_________三个(建议) ___suggest, advise, propose_(recommend)__四个(要求) __require, demand, request, __ask________这些动词后面的宾语从句要使用虚拟语气用法。
即从句中的动词使用should + 动词原形, 或者将should省略。
The doctor suggested that he (should) try to lose his weight.He insisted that we (should) tell him the news.It is arranged that he leave for Canada on Friday.What do you think of his proposal that we should put on a play at the English eveningMy suggestion is that we should go there at once.四.It’s necessary/strange/natural/ important/pity/no wonder/impossible + that Clause 从句中的动词要用虚拟, 即(should)+动词原形I It is a great pity that you (should) think so.It is highly desirable that a new president be appointed for this college.It is strange that the girl(should)be so arrogant.五. would rather 后的宾语从句,用虚拟语气I would rather you could teach me again.The manager would rather that his secretary went to the meeting instead of him .六. as if, as though引导的从句, 用虚拟语气以as if 、as though(似乎,仿佛)引出的方式状语从,如果表示真实情况应该用直陈语气;如果表示非真实情况,都必须用虚拟语气。
当从句表示与现在的事实相反,谓语动词用一般过去时;表示与过去事实相反要用"had +过去分词";表示与将来可能相反的则用"would(could,might)+动词原形"。
The little boy knows so many things as if he were an adultHe acted as usual as though nothing had happened.七. 由if only (要是……,那该多好啊!)引导的惊叹句,用虚拟语气If only I had passed the test !If only it stopped raining!If only I had taken mother's advice比较if only与only ifonly if表示“只有";if only则表示"如果……就好了"。
If only也可用于陈述语气。
I wake up only if the alarm clock rings. 只有闹钟响了,我才会醒。
If only the alarm clock had rung. 当时闹钟响了,就好了。
If only he comes early. 但愿他早点回来。
八. It is (high) time thatIt is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形,但should不可省略。
It is time that the children went to bed.It is high time that the children should go to bed.It is high time that we had our lunch. 该是我们吃午饭的时候了。
It is time that he made up his mind. 该是他作出决定的时候了。
九、在和idea,necessity,plan, motion,order,proposal,recommendation,suggestion,under- standing 等词有关的同位语或表语从句中,谓语动词用动词原形或"should +动词原形"表示虚拟语气。
My idea is that the group(should)hold another session to discuss the problem.Emphasis is laid on the necessity that all the objectives to be attained be taken into account before starting a new project.十、虚拟语气用在简单句中,表示祝愿,命令。
May you be happy. 祝你幸福。
May you have a good time. 祝愿你玩的痛快十一、情态动词中的虚拟语气didn't need to do表示:过去不必做某事, 事实上也没做。
.needn't have done表示:过去不必做某事, 但事实上做了。
John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽,所以她不必步行回家了。
