大學英語六級虛擬語氣例題解析(一)
1、 Jean Wagner’s most enduring contribution to the study of Afro-American poetry is his insistence that it in a religious, as well as worldly, frame of reference.
A. is to be analyzed B. has been analyzed
C. be analyzed D. should have been analyzed
解析：(C)在表示要求、愿望、建議、請求、命令等含義的名詞同位語從句中，從句謂語動詞要用虛擬語氣形式，即should(可以省略)+動詞原形。
2、 I would have gone to visit him in the hospital had it been at all possible, but I ______ fully occupied the whole of last week.
A. were B. had been C. have been D. was
解析：(D)本道題目的前半句話是對過去情況的一種假設，但事實上并沒有發生，而事實上沒有發生的真實原因是句子的后半部分由but引導的轉折句所表述的真實。因而but所引導的句子中應該用表示志過去事實相符合的表陳述的時態，即一般過去時。
3. I apologize if I you, but I assure you it was unintentional.
A. offend B. had offended C. should have offended D. might have offended
解析：(B)此題要求在if從句中選擇適當的動詞形式，以主句中的動詞apologize(抱歉)來看，if從句中表達的內容應該是過去做的事，因此可以排除(A)，因為(A)是現在時。(C)中should+have+過去分詞結構表示本來應該做卻沒有做的事，在此不合題意。(D)選項中的might+have+過去分詞表示對過去發生的事情很不肯定的猜測，它表達的內容還不能成為事實，所以藉此道歉真是不知從何說起，因此此處也不合題意。(B)had offended表示當時已經發生了的動作。這是復雜條件句：apologize 是現在，而條件句是表示對過去假設的條件句。
4. If you hadn’t taken such a long time to get dressed, we’d there by now.
A. be B. circles C. is circling D. be circling
解析：該句也是一個復雜條件句(或稱作混合虛擬條件句)。條件句表示對過去情況的假設，而主句表示對現在情況的假設，但事實上卻與此相反，所以正確答案應該是(A)。
5. The sun rises in the east and sets in the west, so it seems as if the sun ________round the earth.
A. were circling B. circles C. is circling D. be circling
解析：if引導的從句要求用虛擬語氣，表示同時或將來的情況，動詞要用過去式(be動詞用were)或would(could等)+動詞原形，本句話中指的是當時的情況，所以要用過去式，故(A)是正確答案。
6. If the Watergate Incident______ Nixon would not have resigned from the presidency.
A. did not occur B. had not occurred C. was not occurring D. be circling
解析：(B)had not occurred表示對過去的虛擬，條件句中要用過去完成式，主句中要用should(would, could, might)+動詞原形的過去分詞。
7. I hadn’t expected James to apologize but I had hoped ______ .
A. him calling me B. that he would call me C. him to call me D. that he call me
解析：(B)had hoped是常見的要求其后的賓語從句用虛擬語氣的句型,虛擬語氣would+動詞原形。
8. George would certainly have attended the proceedings ______ .
A. if he didn’t get a flat tire B. if the flat tire hadn’t happened
C. had he not had a flat tire D. had the tire not flattened itself
解析：表示對過去情況的假設，主句動詞形式為would(should, could, might)+have+過去分詞，條件句為過去完成式，if可以省略，但要把had提前主語前面。(B)，(D)的表達不符合英語表達習慣，所以(C)是正確答案。
9. The teacher suggested that her students ______experiences with ESP.
A. write a composition on their B. to write composition about the
C. wrote some compositions of his or her D. had written any compositions for his
解析：(A)suggest后面的從句要用虛擬語氣形式，其形式為should(可以省略)+動詞原形。
10. He speaks Chinese as fluently as if he ______a Chinese.
A. were B. had been C. is D. has been
解析：(A).表示與現在相反的虛擬。
大學英語六級虛擬語氣例題解析(二)
1. As usual, he put on a show as though his trip______ a great success.
A. had been B. has been C. were D. was
解析：A.as though引導的與過去相反的虛擬。
2. Looking round the town, he felt as though he ______ away for ages.
A. has been B. was C. is D. had been
解析：D.felt是過去式，所以該句是由as though引導的與過去相反的虛擬。
3. John is so strongly built that he looks as if he ______ as elephant.
A. lifts B. is lifting C. lifted D. could lift
解析：D.as if引導的與現在事實相反的虛擬。
4. He described the town as if he ______ it himself.
A. had seen B. has seen C. saw D. sees
解析：A.as if引導的與過去相反的虛擬。
5. Most insurance agents would rather you______ anything about collecting claims until they investigate the situation.
A. do B. don’t C. didn’t D. didn’t do
解析：(D)would rather后接從句要求用虛擬語氣，形式為過去式，表示對現在或將來的假設，或為過去完成式表示對過去的情況的假設。6. Although most adopted persons want the right to know who their natural parents are, some who have found them wish that they ______ the experience of meeting.
A. hadn’t B. didn’t have had C. hadn’t had D. hadn’t have
解析：(C)who引導的定語從句中的現在完成時表示動作業已發生，所以主句中表示的虛擬是針對已經發生了的行為，所以應該用過去完成式表示對過去的虛擬。
7. Without electronic computers, much of today’s advanced technology ______ .
A. will not have been achieved B. have not been achieved
C. would not have been achieved D. had not been achieved
解析：(C)這是一人含蓄虛擬條件句，通過介詞短語without,表示潛在的一種假設，而主句中的情況也早已經發生，所以是對過去情況的一種假設，因此用would not have been achieved這一形式。
8. He told her to return the book in time so that others ______ a chance to read it .
A. may have B. will have C. would have D. might have
解析：(D)連so that引導的從句中要求用虛擬語氣，表示一種假設，形式為might+動詞原形。
9. It is time that the government ______ measures to protect the rare birds and animals.
A. takes B. took C. has taken D. taking

10. He was very busy yesterday, otherwise he ______ to the meeting.
A. would come B. came C. would have come D. had come
解析：(C)otherwise用來表示一種含蓄的虛擬假設，因為是對過去(yesterday)的情況的假設，所以應該用would have come形式。
大學英語六級虛擬語氣例題解析(三)
1. I must say he reads very well, and I shouldn’t be surprised if he ______ acting for a living one day.
A. had taken up B. takes up C. have taken up D. would have taken up
解析：(B)所給的四個選項中沒有一個表示對未來的情況的虛擬的形式should+動詞原形，或是were to do，因此可以斷定if引導的條件句在這里最真實的條件句，用一般現在時表示一般將來時，故(B)是正確答案。
2. If I had seen the movie, I ______ you all about it now.
A. would tell B. will tell C. have told D. would have told
解析：(A)這是一個混合虛擬語氣的句子，if條件句表示的是對過去情況的假設，而主句是對現在(now)的情況的假設，故用would tell形式。
3. I’d rather you ______ anything about it for the time being.
A. do B. didn’t do C. don’t D. didn’t
解析：B.would rather引導的虛擬語氣其謂語用過去式。
4. Mary ______ my letter； otherwise she would have replied before now.
A. has received B. ought to have received
C. couldn’t have received D. shouldn’t have received
解析：C.注意單詞otherwise引導虛擬語氣。
5. We didnt know his telephone number, otherwise we _____ him. ( 1995年6月四級第46題)
A) would have telephoned B) must have telephoned
C) would telephone D) had telephoned
解析：本題是與過去時相反的虛擬句，從句中用過去完成式，主句中用would have done。本句相當于if we had known his telephone number，we would have telephoned him。答案是(A) would have telephoned。
6. Jean doesnt want to work right away because she thinks that if she ______ a job she probably wouldnt be able to see her friends very often.(1996年1月四級第44題)
A. has to get B. had got C. were to get D. could have got
解析：本句的意思是：“瓊不想馬上就工作，她認為要是找了工作，就不能經常探訪她的朋友了”。這說明，瓊目前沒有工作。句中假設的情況在近期內并不會存在。該條件句應當用表示將來情況的虛擬語氣。條件從句的謂語用should或were to引出。因此C. were to get 是本題答案。選項A. has to get是陳述語氣的現在時，不能用于虛擬條件句中。選項B. had got是虛擬語氣的過去時，不能表示將來時間。選項D. could have got不能用于虛擬語氣的條件從句中。
7. Look at the terrible situation I am in! if only I ____ your advice.(1993年6月四級第70題)
A. follow B. had followed C. would follow D. have followed
解析：if only 引出感嘆句，意思是“要是……多好”，表示說話人的一種愿望，希望發生(事實上不可能發生)與過去事實相反的情況。本句的全句意思是：“看我現在的處境多糟糕!要是我聽從你的勸告多好”。事實上，句中的“我”沒有聽從勸告，所以處境很糟糕。題中空格處應當用虛擬語氣，答案是B。
8 .That tree looked as if it _____ for a long time.
a.hasnt watered b.had not been watered
c.didnt water d.wasnt watered
解析：本題測試as if 從句的虛擬語氣。一般來說，as if 從句所表達的內容完全與實際情況相反或純粹是一種假設時，通常使用虛擬語氣。
9. Id rather you ____ anything about it for the time being.
a. dont do b.did
c.didnt do d.would do
解析：would rather 表示愿望，后接從句用虛擬語氣，用過去時。
10. Look at the terrible situation I am in! If only I ____ your advice
a.follow b.would follow
c.had followed d.have followed
解析：本題測試if only 引起的感嘆句的虛擬語氣。if only 引起的感嘆句，相當于“how I wish +賓語從句”。其謂語動詞形式與wish后的賓語從句形式相同。

a. be put off b. was put off c. should put off d. is to put off

4. Christie stared angrily at her boss and turned away, as though _____ out of the office.
A. went B. gone C. to go D. would go
解析：答案為：C. to go 。 as though或as if引導的狀語從句中,從句主語和主句主語相同時,從句中可省略主語和部分謂語,如：1) She paused, as if to let the painful memories pass. (省略she wanted)
2) From time to time Jason turned round as though searching for someone. (省略he were)
3) The boy started, as if awakened from some dream. (省略he were)

A. would go B. should go C. went D. had gone
解析：“我寧愿你乘火車去，因為我無法想像在如此惡劣的天氣你呆在飛機里�！敝髡Z+would rather后接賓語從句,從句中謂語須用虛擬語氣：用一般過去時表示希望現在或將來實現的行為或狀態,用過去完成時表示希望過去實現的行為或狀態。本題中原因狀語從句用一般現在時,暗示希望現在或將來發生的行為動作,故選答案為 C. went。

9. Had he worked harder, he _____ the exams.
A. must have got through B. would have got through
C. would get through D. could get through
解析：本題前半句是表示與過去事實相反的虛擬條件從句，后半句是表示與過去事實相反的主句。相當于：If he had worked harder, he would have got through the exams.本題的答案是B. would have got through。選項A. must have got through(肯定通過)表示一種對過去事情的主觀推測，不是與過去事情相反的情況。另外，must不能用在虛擬條件句中。選項C.
would get through(就會通過)是虛擬語氣現在時的一種表示方法，表示與現在事實相反。選項D. could get through(可能通過)，could也可以用于非真實條件句里，表示與事實相反的情況，但這里，它只表示與現在事實或將來可能的事實相反。

虛擬語氣知識點
1. 表示現在/過去/將來情況的虛擬條件句
虛擬條件句主要有三種結構：
1) 表示與現在情況相反：主句謂語用“would / could / might +動詞原形”，從句謂語用“動詞的一般過去時”(動詞be的過去式一律用were)。
If I were you, I would not accept his offer.
If I had time, I would certainly go to the cinema with you.
2) 表示與過去情況相反：主句謂語用“would / could / might + have +過去分詞”，從句謂語用過去完成時。
If I had got up a little earlier, I wouldn’t have missed the train.
If I had been more careful, I might have passed that exam.
3) 表示與將來情況相反：主句謂語用“would / could / might +動詞原形”，從句謂語用“were +動詞不定式”或“should +動詞原形”。
If I were to do the job, I would not be able to have enough time to study.
If it should rain tomorrow, I would not go out with you.
2. 虛擬條件句連接詞if的省略
如果虛擬條件句的從句中含有were, had, should, could等詞時，可以省略連接詞if，但這時必須把were, had, should, could等詞移到主語前面，形成倒裝。這種句型主要用于書面形式。
Were I to do the job, I would finish doing it within two weeks.
Had it not been for his help, we couldn’t have arrived there on time.
Should it rain tomorrow, I would stay at home.
3. wish后賓語從句中的謂語構成
動詞wish后的賓語從句表示未實現的或不可能實現的愿望，其賓語從句中的謂語動詞要用虛擬語氣，有以下三種構成形式。

I wish I had enough money to buy a car.
I wish I were as young and energetic as you.

6. 錯綜時間條件句
條件從句表示的動作和主句表示的動作，有時發生的時間是不一致的.如從句是對過去情況的假設，而主句可能是對現在正在進行情況的假設。 這種句子稱為錯綜時間條件句.
If the weather had been more favourable, the crops would be growing still better.
