36. 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月四级第44题)

　　A. has to get 　　B. had got 　　C. were to get 　　D. could have got

　　解析：本句的意思是：“琼不想马上就工作，她认为要是找了工作，就不能经常探访她的朋友了”。这说明，琼目前没有工作。句中假设的情况在近期内并不会存在。该条件句应当用表示将来情况的虚拟语气。条件从句的谓语用should或were to引出。因此C. were to get 是本题答案。选项A. has to get是陈述语气的现在时，不能用于虚拟条件句中。选项B. had got是虚拟语气的过去时，不能表示将来时间。选项D. could have got不能用于虚拟语气的条件从句中。

　　37. Look at the terrible situation I am in! if only I ____ your advice.(1993年6月四级第70题)

　　A. follow 　　B. had followed 　　C. would follow 　　D. have followed

　　解析：if only 引出感叹句，意思是“要是……多好”，表示说话人的一种愿望，希望发生(事实上不可能发生)与过去事实相反的情况。本句的全句意思是：“看我现在的处境多糟糕!要是我听从你的劝告多好”。事实上，句中的“我”没有听从劝告，所以处境很糟糕。题中空格处应当用虚拟语气，答案是B。

　　38 .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：本题测试as if 从句的虚拟语气。一般来说，as if 从句所表达的内容完全与实际情况相反或纯粹是一种假设时，通常使用虚拟语气。

　　39. 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，后接从句用虚拟语气，用过去时。

　　40. 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：本题测试if only 引起的感叹句的虚拟语气。if only 引起的感叹句，相当于“how I wish +宾语从句”。其谓语动词形式与wish后的宾语从句形式相同。

　　41. We are all for your proposal that discussion _____.(1998年6月四级第68题)

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

　　解析：全句意思是：我们都赞成你的建议，把讨论推迟。答案是A。虚拟语气在定语从句中的应用

　　在It's (high) time 之后的定语从句中需用虚拟语气。谓语动词用过去式。

　　42. It's already 5 o'clock now. Don't you think it's about time _____ ?(1995年6月四级第43题)

　　A. we are going home 　　B. if she leaves C. we went home 　　D. if she had left

　　解析：“现在已经十六点钟了，难道你不认为该回家了吗?”句中的“it's about time …”引起虚拟。因此答案是C。

　　43. The mad man was put in the soft-padded cell lest he _____ himself.(1998年1月四级第38题)

　　a. injure　　b. injured 　　c. had injure　　d. would injure

　　解析：“这个疯子被关进墙上装有衬垫的病房，以免伤了他自己。”在lest 引导的状语从句中，谓语动词多用虚拟语气，(should )+ 动词原形。答案是a。

　　44. 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：答案为：C. to go 。 as though或as if引导的状语从句中,从句主语和主句主语相同时,从句中可省略主语和部分谓语,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)

　　由此可见,本题中省略she wanted。

　　45. 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：“我宁愿你乘火车去，因为我无法想像在如此恶劣的天气你呆在飞机里。”主语+would rather后接宾语从句,从句中谓语须用虚拟语气：用一般过去时表示希望现在或将来实现的行为或状态,用过去完成时表示希望过去实现的行为或状态。本题中原因状语从句用一般现在时,暗示希望现在或将来发生的行为动作,故选答案为 C. went。

　　46. 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：“要不是老百姓的及时投资，我们的公司不会像现在这样兴旺。”本题测试交错时间的虚拟语气。从句是表示过去时间的虚拟条件，if省略，主语it与助动词had倒装。虚拟条件句也可写成这样：If it had nor been for the timely investment from the general public。这是重点句型，在各类测试中常考。答案： A. Had it not been

　　47. 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：“一次安全隐患分析本来会确认这个目标是潜在的危险。不幸的是，这样的分析从未做过。”这是对过去时间的虚拟，表示过去要做而没有做的事。因而答案选 C. would have identified

　　48. In the past men generally preferred that their wives in the home.

　　A. worked　B. would work　C. work　D. were working

　　解析：“过去男子一般都愿意他们的妻子在家里工作。”因为prefer(宁愿)是欲望动词,其后所接的宾语从句中谓语需用(should)+动词原形。 答案：C. work

　　49. 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：本题前半句是表示与过去事实相反的虚拟条件从句，后半句是表示与过去事实相反的主句。相当于：If he had worked harder, he would have got through the exams.本题的答案是B. would have got through。选项A. must have got through(肯定通过)表示一种对过去事情的主观推测，不是与过去事情相反的情况。另外，must不能用在虚拟条件句中。选项C.

　　would get through(就会通过)是虚拟语气现在时的一种表示方法，表示与现在事实相反。选项D. could get through(可能通过)，could也可以用于非真实条件句里，表示与事实相反的情况，但这里，它只表示与现在事实或将来可能的事实相反。

　　50. 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：主语+would rather后接宾语从句,从句中谓语须用虚拟语气：用一般过去时表示希望现在或将来实现的行为或状态,用过去完成时表示希望过去实现的行为或状态。本题中原因状语从句用一般现在时,暗示希望现在或将来发生的行为动作,故选C. went。
