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(dǎo)的條件句在這里最真實(shí)的條件句,用一般現(xiàn)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(shè),而主句是對現(xiàn)在(now)的情況的假設(shè),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(dǎo)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(dǎo)虛擬語氣。
5. We didn't 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(dāng)于if we had known his telephone number,we would have telephoned him。答案是(A) would have telephoned。
6. Jean doesn't want to work right away because she thinks that if she ______ a job she probably wouldn't 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(rèn)為要是找了工作,就不能經(jīng)常探訪她的朋友了”。這說明,瓊目前沒有工作。句中假設(shè)的情況在近期內(nèi)并不會存在。該條件句應(yīng)當(dāng)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(xiàn)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(fā)生(事實(shí)上不可能發(fā)生)與過去事實(shí)相反的情況。本句的全句意思是:“看我現(xiàn)在的處境多糟糕!要是我聽從你的勸告多好”。事實(shí)上,句中的“我”沒有聽從勸告,所以處境很糟糕。題中空格處應(yīng)當(dāng)用虛擬語氣,答案是B。
8 .That tree looked as if it _____ for a long time.
a.hasn't watered b.had not been watered
c.didn't water d.wasn't 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(dá)的內(nèi)容完全與實(shí)際情況相反或純粹是一種假設(shè)時,通常使用虛擬語氣。
9. I'd rather you ____ anything about it for the time being.
a. don't do b.did
c.didn't 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(dāng)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。
