考博英语虚拟语气

一、混合虚拟语气  @ f$P*_G   
  有时主句和从句的谓语动词指不同的时间,这时需要用混合虚拟语气。一般来说,在这种情况下,主从句谓语动词指代的时间不同,所以我们又可以错综时间条件句,在这种虚拟情况,动词形式应根据实际情况灵活使用,在做这些题目时候尤其要注意每道题目的提示语:时间状语。绝大多数情况下,从句或者主句都有相关的时间状语,这是我解题的关键。  Ua:EI!`  
If you    that late movie last night, you wouldn’t be so sleepy.  G{J9Fb8  
A. haven’t watched   B. didn’t watch    HG^8&uh]  
C. hadn’t watched   D. wouldn’t have watched         答案选C。  /v8qT'$^  
Many dead would now be alive if they have not attempted to return for something.  ^b%AwzHH}  
Had Paul received six more votes in the last election, he would be our chairman now.  UeRenp  
  混合虚拟语气还有一种情况就是事实和虚拟假设的混合句,这样的句子不仅仅是时间的不同,而重要是事实和假设的混合。  aCMcu\rd  
I would have gone to visit him in the hospital had it been at all possible, but I was fully occupied the whole of last week.  v|hi;l@7E  
该句前半部分是假设虚拟,而后半部分是事实的陈述。  <sTa Xaq?  
Your math instructor would have been happy to give you a make-up examination had you gone and explained that your parents were ill at the time.  r8 xH A  
  该句前半句用的是假设虚拟,后半句主句也用的是假设虚拟(如果你去并且解释的话),但是后半句的从句用的是事实语气,因为“父母病了”是客观事实,故不需要用虚拟形式had been。  j_{gk"2:d`  
二、含蓄虚拟条件句  BYGLYT;Z  
  含蓄条件句是指句中没有明显的虚拟条件句,而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常来表示含蓄虚拟条件的手段有:  l"- D@]"  
(1)介词或介词短语,如but for, but that, without, in case of, under more favorable condition等。  ^^[,aBu  
      the leadership of the party, we could not be living a happy today.=If there hadn’t been the leadership of the party, we could not be living a happy today. o;O_N^_W  
`w q\K8v  
A. In spite of    B. But for    C. Because of    D. As for    答案选B。   Op|Be  
But that she was afraid, she would have said no.  .OjJK?  
(2)连词,如:so that, unless, in case, supposing, lest, provided(倘若……),for fear that(唯恐),in order that, on condition that, if only(要是……就好了)等。  UeVF@rw  
She listened carefully in order that she might discover exactly what he wanted.=if she listened carefully ,she might discover exactly what he wanted.  )~J/,\  
If only I had more money, I could buy a car.  g ` Wr3  
 (注:lest, for fear that 和 in case 引起的从句中谓语动词多用should+动词原形,但可以不用虚拟语气,而用动词的陈述语气形式。)例如:  <sPB|5Ak  
  The foreign teacher spoke slowly in case we misunderstood him. 这位外籍教师说得很慢以免我们听不懂。  \UiuJ+  
Care must be taken in using this method lest overflow should occur.在使用此法时要小心谨慎,以免会发生溢流现象。  OZ-F+#d  
(3)通过上下文及内在含义,句中往往有but, otherwise, unfortunately等类似转折词。  UVUHLu|^  
I thought the children      when we returned home, but they were still awake.  E 1>3[3  
A. were sleeping   B. would be sleeping   C. had been sleeping    D. would sleep选择 B。  6L4B$'&KQZ  
(4)形容词及其比较级  f[z#=zv  
A more careful person would not have made so many mistakes.  CfVz '  
A less conscientious man wouldn’t have tried so hard to get this job done.  Wl*\kQ}U  
(5)分词短语  kAAz|dhL-  
Having known in time, we might have prevented the accident.  ^EB}e15"  
Born ten days earlier, the boy could have seen his late father.  ;mMn-+3<  
(6)动词不定式短语。一般intended/meant/hoped/wished/planned 或 was/were+不定式完成式或had intended/meant/planned/hoped/wished/+不定式一般式表示虚拟。  3Y=S^*ztd  
I intended I should call on you, but I was busy at that time.  c,+oH<bZZs  
To hear him speak French, you would take him for an Englishman.  v"s}7trWV  
She would be stupid not to accept his invitation.  ^x4gUT-Wy  
It would be easier to do it this way.  2Aff3]-:Gd  
(7)名词短语和名词+and结构  Z,!Rj7wZ  
A judicious man would not have committed suicide.  J${wU @_ %  
A diligent student would have worked harder.  3fGy  
(8)独立主格结构  N!P* B $d  
All things considered, the price would be reasonable.  ,,i;6q_f  
(9)定语从句  b]J_R"}  
Anyone who had been in your position would have done the same.  OnD+/I  
A nation, which stopped working, would be dead in a fortnight.  y<5s)OehG  
(10)情态动词完成式暗示虚拟语气:  zJ#q*2A(Z  
I should have called to make an airline reservation, but I didn’t.  `OBDx ^6F

(11)动词原形表示虚拟  YWm:#{n.  
动词原形直接用在句子中也被看作是一种虚拟,最常见于正式文体中,动词原形一般用在条件从句中,有时倒装置于句首,同时这种用法也常见于独立句中表达愿望。  z/;NoQ-  
God bless you!  "--rz;+K  
All magnets behave the same, be they large or small.  (0Y6tcV]R
