insist(坚持)、order/ command(命令)、suggest/ advise/ propose(建议)、demand/ require/ ask/ desire(要求)后面跟虚拟语气。
例1:The examination instructor asked that the students(should)not use a calculator.考官要求学生不要使用计算器。
例2:The workers demanded that their wages(should)be raised by 10 percent.工人们要求增加百分之十的工资。
比较:动词 suggest和insist 后面的宾语从句,应根据不同情况选用陈述语气或虚拟语气。
suggest作“建议”解时,用虚拟语气,作“使想起、暗示”解时,用陈述语
例:His silence suggested that he agreed with my decision.他的沉默暗示他赞同我的决定。(暗示)
例:He suggested that I(should)stick to my decision.他建议我坚持自己的决定。(建议)
insist作“坚决要求”解时,用虚拟语气,作“坚持认为”解时,用陈述语气。
例:He insists that doing morning exercises does good to people's health.他坚持认为做早操对健康有益。(强调)
例:He insists that he(should)do morming exercises every day.他坚持每天都要做早操。(要求)
扩展资料
1、名词性从句中要用过去时或should+动词原型构成虚拟语气。如:It is time we went home.
2、wouldrather,hadrather后的从句动词用相当于陈述语气的过去时来表示现在或将来发生的动作。如:I would rather you went with her.我宁愿你跟她走。
只有当wouldrather后面动作的主体与前面主语一致时才可以用不带to的动词不定式,如:I’d rather take the important letter with me.在这个句子中,rather后面的主语为I,和前面的主语一致,所以用的不是过去式,而是不带to的动词不定式。
3、在itisimportant/suggested/necessary/proposed等结构后的主语从句中要用虚拟语气表示应该做什么事情,即用动词原形或should+动词原型,如:It is important that you(should) be here on time.
4、词组but for相当于were it not for或had it not been for,表示一种含否定意义的条件,后面一般加名词或名词短语,如:He might have been killed but for the arrival of the police.要不是警察来了他本可能被杀死。
5、在某些表示祝愿的句子里需要用虚拟语气,如:May you be happy all your life!
一个坚持(insist),两个命令(order, command),三个建议(suggest, advise, recommend),四个要求(ask, require, demand, request)。
1、要求/请求”类宾语从句英语中某些表示“要求”意义的动词,后接宾语从句时,通常要用“should+动词原形”这样的虚拟语气(在美国英语中),这些动词主要包括ask(要求), beg(请求), demand(要求), desire(要求), insist(坚持要求), request(要求), urge(迫切要求)等。
如:I ask that he leave. 我要求他走开。
2、“建议”类宾语从句英语中某些表示“建议”意义的动词,后接宾语从句时,通常要用“should+动词原形”这样的虚拟语气,这些动词主要包括advise(建议), move(提议), propose(建议), recommend(建议), suggest(建议)等。
如:The doctor advised that he change his job. 医生劝他换工作。
3、“命令”类宾语从句英语中某些表示“命令”意义的动词,后接宾语从句时,通常要用“should+动词原形”这样的虚拟语气,这些动词主要包括order(命令), command(命令), direct(指示、命令)等。
如:He ordered that the goods should be sent by air. 他命令货物得空运。
4、决定”类宾语从句英语中某些表示“决定”意义的动词,后接宾语从句时,通常要用“should+动词原形”这样的虚拟语气,这些动词主要包括decide, determine等。
如:She determined that he should study music. 她下决心要他学习音乐。

其他用法:
1、would rather
因为本身would rather可以直接接动词原形,构成would rather do sth. (than do sth.else); 或者would do sth. rather than do sth.else。而虚拟语气的would rather 是这样使用的would rather sb. did(对现在或将来的假设)/ had done(对过去的假设)
2、for fear that
后面可以接虚拟语气should do,也可以接其他语气,但依然会有一个情态动词。
3、wish
后面的宾语从句,谓语动词要用虚拟语气,其形式主要有三种wish sb. did(对现在的虚拟); wish sb. had done(对过去的虚拟); wish sb. would do (对将来的虚拟).偶尔在对过去的虚拟时,也会出现wish sb. would have done的情况。

过去分词有:
desired, demanded, ordered, requested, suggested, recommended, required等.
例如:
It is essential that you (should) win the voters’hearts.赢得选民的心是绝对必要的.
It was suggested that he (should) join the club activities.有人提议他应该参加俱乐部的活动.
2.表语从句和同位语从句中的虚拟语气在表示建议、命令、主张、目的和愿望等名词后面的表语从句和同位语从句中谓语动词要求使用虚拟语气.其形式为:(should)+动词原形.
常这样用的名词有:
resolution决心,决议pray恳求decision决议motion提议suggestion建议preference选择proposal提议advice劝告recommendation推荐desire愿望demand要求requirement要求order命令necessity必要性request要求idea主意、想法例如:

His proposal is that we (should) get rid of the bad habits.他提议我们应该摈弃这些不良习性.
3.宾语从句中的虚拟语气
1)某些动词后所接宾语从句中的谓语动词要求用虚拟语气,用来表示建议、命令和要求等.其形式为:(should)+动词原形.常这样用的动词有:
ask要求advise劝告determine决定decide决定command命令insist坚持intend打算move提议prefer宁愿propose提议order命令recommend推荐request要求require要求suggest建议urge主张demand要求desire渴望direct命令例如:
He insisted that the meeting be put off.他要求推迟那个会议.
They proposed that all the plans should be discussed at the meeting.他们建议所有的计划都应该在会上讨论.
2)在以it为形式宾语的复合宾语从句中也可以用虚拟语气,其形式为:(should)+动词原形.这一句型中使用的形容词(宾补)与主语从句中的虚拟语气所使用的形容词相同.例如:
We think it advisable that he (should) think deeply before acting.我们认为他在行动之前好好考虑一下才是明智的.
3)wish后面所跟的宾语从句中的虚拟语气表示某种不能实现的愿望.
其主要形式有三种:
表示对现在情况的虚拟:wish +主语+动词过去式或were表示对过去情况的虚拟:wish +主语+ had +过去分词表示对将来情况的虚拟:wish +主语+ would +动词原形.
例如:
I wish I knew what was going to happen.但愿我能知道要发生什么事.
She wished she had stayed at home.她懊悔的是她当时要是在家就好了.
I wish I were rich.我恨不得我很有钱.
注意:在表示对过去情况的虚拟时,有时也可以用下列形式:
wish +主语+ would(could)+ have +过去分词I wish I could have seen her last night.要是我昨天晚上能够见到她那该多好.
4. if条件句中的虚拟语气形式1)if非真实条件句所表示的假设则是不可能或不大可能发生或实现的,句中的主句与从句都用虚拟语气.
在if非真实虚拟条件句中,主句和从句谓语动词主要有下面几种形式:
假设类型条件从句谓语动词形式主句谓语动词形式与现在事实相反动词过去时(be用were)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可能相反动词过去时(should+动词原形,were to +动词原形)Should(would,could,might)+动词原形
If there were no gravity, we should not be able to walk.假如没有引力,我们就不可能行走.
I wouldn’t have known what these were for if I hadn’t been told.假如别人不告诉我,我就不知道这些东西是干什么的了.
2)正式文体中,有时可把虚拟条件句中的连词if省去,而将were,had, should等助动词(不包括行为动词)提到主语前面.如果句中没有were,had或should时,既不能省略if,也不能倒装.例如:
Were I to meet him tomorrow (= If I were to met him tomorrow), I should ask him about it.要是我明天见到他,我就会问他这件事的.
Had I had the money last year (= If I had had the money last year), I would have bought the house.如果我去年有了这笔钱,我就买那所房子了.
Should there be any trouble with the boiler, the automatic controlling unit would cut off the fuel oil supply.假如锅炉出问题的话,自控装置会自动切断燃油的供给.
3)通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的,但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式.例如:
If I were you, I would have taken his advice.我要是你,我就采纳了他的建议.(从句指现在,主句指过去)
If the weather had been more favorable, the crop would be growing still better.如果气候更适宜一些,庄稼会长得更好.(从句指过去,主句指现在)
5.含蓄虚拟条件句1)有时假设的情况并不以条件从句形式表示出来,而是通过一个介词短语或其他方式表示.常用的词或短语有:without, but for, but that, otherwise, or, but等.例如:
Without your help (=If we had not had your help), we could not have succeeded.要是没有你的帮助,我们就不会成功的.
But for electricity (= If there were no electricity), there would be no modern industry.要是没有电,就不会有现代工业.
He was having a meeting; otherwise he would have come over to help us.他当时正与他的学生进行讨论,否则的话他就来帮我们了.
He felt very tired yesterday, or he would have attended the party.他昨天很累,不然他就参加那个聚会了.
2)在某些暗含虚拟条件的简单句中,虚拟语气可通过上下文表现出来.谓语动词用should/ would be形式和should/ would have been虚拟形式.例如:
Any men in his position would have done like that.任何人处在他的位置都会那么做的.
You should (ought to) have come earlier.你本应来得早点.
6.其他句型中的虚拟语气1)在would rather, would sooner, would just as soon, might as well和would prefer等后面所跟的从句中,也可以用虚拟语气,表示愿望,意为“宁愿、但愿”.其形式为:
①“would rather (would sooner…) +主语+谓语动词过去式”表示现在或将来的情况.
②“would rather (would sooner) +主语+动词过去完成式”表示过去的情况.例如:I’d rather he didn’t go now.要是他现在不走就好了I’d just as soon you had been here yesterday.要是你昨天在这里就好了.
2)在句型“It is (high/ about) time…”后面也可以跟虚拟语气,从句中常用过去式.有时也用“(should)+动词原形”,意为“该是……的时候了”.例如:
It is time that the boy (should) go to school.这个小孩该上学了.
It is high time (that) the weather improved.天气真该好起来了.
3)在“if only”引起的感叹句中也要求用虚拟语气,表示愿望.
形式为:①用过去时或“would/ could +动词原形”表示与现在或未来事实相反的愿望.
②过去完成时表示与过去事实相反的愿望.例如:
If only you would listen to our advice.要是你听我们的建议就好了.
If only I had not been busy last week!要是上周我不忙该多好啊!
If only she could marry me.但愿她能嫁给我.
注:if only也可以用于虚拟条件句中.例如:
If only I had more money, I could buy a car.要是我有更多的钱,我就可以买辆车了.
4)连接词“in case, lest, for fear that”可以用来引导虚拟语气.其形式通常为:“…lest (in case, for fear that) +主语+ should +动词原形”.Lest, for fear that句中的should可以省去,in case句中的should通常不省去,但是in case句中可以不用虚拟语气,而用陈述语气.Lest, for fear that后面也可以接其他形式.例如:
He took his coat with him in case it should rain.他带着雨衣以防下雨.
I will not make a noise for fear that I (should/ might) disturb you.我不会做声的,以免打扰你.
Care must be taken in using this method lest overflow (should) occur.在使用这以方法的时候要谨慎小心,以免发生溢流现象.
