初中英语虚拟语气讲解及练习

英语中的语气分为陈述语气、祈使语气、虚拟语气三类。

虚拟语气表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。

如果假设的情况可能发生,是真实条件句,这种情况下谓语用陈述语气。如:If time permits, we'll go fishingtogether.如果时间允许,我们就一起去钓鱼。

如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。如: If you had come yesterday, youwould have met that famousprofessor.如果你昨天来,你就会见到那位著名的教授了。(隐含的事实是:你昨天没来,也没见到那位著名教授)。

虚拟语气的基本形式和用法在含有虚拟条件句的复合句中,主从句的谓语都要用虚拟语气。

1.含有条件状语从句的复合句
 wish(wouldrather)+宾语从句
  suggest(…)+宾语从句
2.主语从句Itis+adj./p.p/n.+that+S+(should)+do
表语从句S+isthat+s+(should)+do
同位语从句S+that+s+(should)+do

3.定语从句Itis(high)timethat+S+did
用过去式表现在情况
1.时态后退型用过去完成式表过去
两种形式用过去将来表将来
2.should+动词原形型

内容详述

I.含有条件状语从句的复合句(以do为例;S=主语)
时间条件状语从句主句
与现在事实相反的假设If+S+did…S+would/should/could/might+do…
与过去事实相反的假设If+S+haddone…S+would/should/could/might+havedone…
与将来事实相反的假设did…
If+Sshoulddo
weretodo
S+would/should/could/might+do…
注意事项:
1.倒装句。如果条件句中含有功能词had,should,were时,可以省去If,把功能词提前,构成倒装句。
2.错综条件句。若条件句和主句动作不存在同一个时间,则谓语形式应根据具体情况而定。
3.Ifthereweren't/hadnotbeen+…=without…
4.Ifitwerenotfor…/Ifithadn'tbeenfor…=butfor…
5.otherwise+虚拟语气的句子
6.虚拟语气的句子,but+陈述事实的句子
II.虚拟语气用在宾语从句中
sb.did…(希望现在用过去式)
1.wish+thatsb.haddone…(希望过去用过去完成式)
sb.would/shoulddo(希望将来用过去将来)
2.wouldrather后的从句要用虚拟语气。
时间从句
虚拟现在were,did(动词一般过去式)
虚拟过去haddone
虚拟将来did(动词一般过去式)
例:IwouldratherIhadn’tsaidsuchunkindthingstoyou.(虚拟过去)
I'dratheryoucameherefortheanswertomorrowmorning.(虚拟将来)
I’dratheryoupostedtheletterrightaway.(虚拟现在)
3.suggest+(that)S+should+do…
表示愿望、建议、请求等主观意向的动词之后的宾语从句,谓语用should+动词原形,should常常省略。
这类词有:decide,demand,desire,insist,order,propose,suggest,recommend,requested,require等。
注意:
1.suggest当“建议”讲时,其宾语从句用虚拟语气;当“暗示、表明”时,用陈述语气
2.insist当坚持“看法或建议”时,宾语从句用虚拟语气;当坚持“某个事实”时,用陈述语气。
 判断改错:(错)Yourpalefacesuggeststhatyou(should)beill.
(对)Yourpalefacesuggeststhatyouareill.
 (错)Iinsistedthatyou(should)bewrong.
 (对)Iinsistedthatyouwerewrong.
III.虚拟语气用在主语从句中
Itisdemanded/necessary/apity+that…等结构的主语从句,谓语动词用should加动词原形,should可省略。
Itis可用的词有三类that(should)do
suggested,ordered,required,proposed,demanded,requested,insisted等
important,necessary,natural,imperative,strange等
apity,ashame,nowonder等

IV.虚拟语气用在同位语从句中。
某些表示建议、请求、命令等主观意向的名词后同位语从句需用虚拟语气,其表达形式为(should)+动词原形。
这类名词常见的有:advice,suggestion,proposal(提议),order,demand,desire,request,requirement,recommendation(推荐),plan,resolution(决议),idea等。
eg.Weareallforyourproposalthatthediscussion(should)beputoff.
V.虚拟语气用在表语从句中。
某些表示建议、请求、命令等主观意向的名词作主语时,表语从句需用虚拟语气,其表达形式为(should)+动词原形。
这类名词常见的有:advice,suggestion,proposal,order,demand,desire,request,requirement,recommendation以及plan,idea,resolution等。
eg.Mysuggestionisthatthemayor(should)presenttheprizes.
VI.虚拟语气用在定语从句中
Itis(about/high)time+thatsb.didsth/shoulddosth..
eg.Don'tyouthinkit'sabouttimewewenthome?
注:在thisisthefirsttime/secondtimethat...句型中,从句中谓语动词用陈述语气完成时态。
eg.IsthisthefirsttimethatyouhavevisitedHongkong?
VII.虚拟语气用在让步、方式、目的状语从句中
1.在带有evenif/eventhough引导的让步状语从句的主从复合句中,主句和从句都用虚拟语气,动词形式与含有非真实条件句的虚拟语气相同。如:Evenifhehadbeenill,hewouldhavegonetohisoffice.即使生了病,他俩去办公室。
2.由asif或asthough引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或“had十过去分词”。如:HetreatedmeasifIwereastranger.他那样对待我,好像我是陌生人似的。Shetalkedaboutthefilmasifshehadreallyseenit.她谈论那部影片,就好像她确实看过一样。
3.虚拟语气用在lest(唯恐、免得),forfearthat及incase引导的目的状语从句中。在由lest等引导的目的状语从句中需用虚拟语气,表示“以防,以免”等意思,其谓语动词多由should+动词原形构成,should也可省略。
eg.Hewaspunishedlestheshouldmakethesamemistakeagain.
VIII.虚拟语气用情感语言中
1.虚拟语气在表示客气、遗憾以及祝愿等场合中,使用虚拟语气。
eg.Youshouldn'thavebeenfollowinghimsoclosely;youshouldhavekeptyourdistance.
2.Ifonlysb./sth.+时态后退型的谓语

eg.IfonlyIhadknowntheresultoftheexamination.

IX.虚拟语气的特殊用法:

1. 省掉if的条件从句结构:

Hadyou asked me, I would have told you.

(=If you had asked me,…)

2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示,如:

A true friend wouldnot do such a thing.

(=If he were a true friend, hewould...)

3.有时条件从句中的动作和结果从句中的动作发生的时间不一致,如:

If he had followed the doctor’s advice, he would be quite all rightnow.

If I were you, I would have gone home.
