下面是英語六級虛擬語氣例題解析(四)，供考生學習。
　　1. We are all for your proposal that discussion _____.(1998年6月四級第68題)
　　a. be put off 　　b. was put off 　　c. should put off 　　d. is to put off
　　解析：全句意思是：我們都贊成你的建議，把討論推遲。答案是A。虛擬語氣在定語從句中的應(yīng)用
　　在It's (high) time 之后的定語從句中需用虛擬語氣。謂語動詞用過去式。
　　2. It's already 5 o'clock now. Don't you think it's about time _____ ?(1995年6月四級第43題)
　　A. we are going home 　　B. if she leaves
　　C. we went home 　　　　D. if she had left
　　解析：“現(xiàn)在已經(jīng)十六點鐘了，難道你不認為該回家了嗎?”句中的“it's about time …”引起虛擬。因此答案是C。
　　3. The mad man was put in the soft-padded cell lest he _____ himself.(1998年1月四級第38題)
　　a. injure　　b. injured 　　c. had injure　　d. would injure
　　解析：“這個瘋子被關(guān)進墻上裝有襯墊的病房，以免傷了他自己。”在lest 引導的狀語從句中，謂語動詞多用虛擬語氣，(should )+ 動詞原形。答案是a。
　　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)
　　由此可見,本題中省略she wanted。
　　5. I'd rather you _____ by train, because I can't bear the idea of your being in an airplane in such bad weather.
　　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。”主語+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(xiàn)在或?qū)韺崿F(xiàn)的行為或狀態(tài),用過去完成時表示希望過去實現(xiàn)的行為或狀態(tài)。本題中原因狀語從句用一般現(xiàn)在時,暗示希望現(xiàn)在或?qū)戆l(fā)生的行為動作,故選答案為 C. went。
　　6. _____ for the timely investment from the general public,our company would not be so thriving as it is.
　　A. Had it not been　B. Were it not　C. Be it not　D. Should it not be
　　解析：“要不是老百姓的及時投資，我們的公司不會像現(xiàn)在這樣興旺。”本題測試交錯時間的虛擬語氣。從句是表示過去時間的虛擬條件，if省略，主語it與助動詞had倒裝。虛擬條件句也可寫成這樣：If it had nor been for the timely investment from the general public。這是重點句型，在各類測試中常考。答案： A. Had it not been
　　7. A safety analysis _____ the target as a potential danger. Unfortunately, it was never done.
　　A. would identify 　B. will identify
　　C. would have identified　D. will have identified
　　解析：“一次安全隱患分析本來會確認這個目標是潛在的危險。不幸的是，這樣的分析從未做過。”這是對過去時間的虛擬，表示過去要做而沒有做的事。因而答案選 C. would have identified
　　A. worked　B. would work　C. work　D. were working
　　解析：“過去男子一般都愿意他們的妻子在家里工作。”因為prefer(寧愿)是欲望動詞,其后所接的賓語從句中謂語需用(should)+動詞原形。 答案：C. work
　　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(xiàn)在時的一種表示方法，表示與現(xiàn)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(xiàn)在事實或?qū)砜赡艿氖聦嵪喾础?br />　　10. I'd rather you _____ by train, because I can't bear the idea of your being in an airplane in such bad weather.
　　A. would go　B. should go　C. went　D. had gone
　　解析：主語+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(xiàn)在或?qū)韺崿F(xiàn)的行為或狀態(tài),用過去完成時表示希望過去實現(xiàn)的行為或狀態(tài)。本題中原因狀語從句用一般現(xiàn)在時,暗示希望現(xiàn)在或?qū)戆l(fā)生的行為動作,故選C. went。
