(2)由于空格后的 if 条件状语从句的谓语用的是虚拟语气(这是很重要的信息)，所以主句要用 would 而不用 will，即答案应选D.
4. "He will come tomorrow." "But I'd rather he _____ the day after tomorrow."
A. will come B. is coming
C. came D. had come
【陷阱】容易误选A或B.根据上文的 He will come tomorrow 以及下文的时间状语 the day after tomorrow 似乎都表明空白处应填一个一般将来时态。
【分析】但此题的最佳答案是 C.按照英语习惯，would rather 后接that 从句时，从句谓语通常要用虚拟语气，即用过去式表示现在或将来，用过去完成时表示过去。又如：
I'd rather you left right now. 我宁愿你现在就离开。
I would much rather it was forgotten. 我更愿这事被遗忘掉。
I'd rather he hadn't told me about it. 我宁愿他没告诉我这事。
请再做以下试题(答案均为B)：
(1)"Shall I come tomorrow?" "I'd rather you ______."
A. won't B. didn't
C. don't D. wouldn't
(2)"I've told him about it." "But I'd rather you ______."
A. didn't B. hadn't
C. don't D. wouldn't
(3)"He will take you as well." "But I'd rather he ______."
A. won't B. didn't
C. doesn't D. wouldn't
5. All the doctors in the hospital insisted that he ____ badly wounded and that he ____ at once.
A. should be; be operated on
B. were; must be operated on
C. was; should be operated
D. was; be operated on
【陷阱】几个干扰项均有可能误选。
【分析】最佳答案选 D.insist后的从句谓语有时用"should+动词原形"这样的虚拟语气，有时不用，具体要看该谓语动词所表示的含义。一般说来，若该谓语动词所表示的动作尚未发生，或尚未成为事实，则用虚拟语气;若该谓语动词所表示的动作已经发生，或已经成为事实，则要用陈述语气。分析上题的句意，可知只有选D最合适。请做以下类似试题(答案选B)：
(1)The patient insisted that he _______ ill and _______ to the hospital.
A. wasn't, wasn't sent B. wasn't, shouldn't be sent
C. shouldn't be, wasn't sent D. shouldn't be, shouldn't be sent
(2)The man in prison insisted that he _______ nothing wrong and _______ set free.
A. should do, should be B. had done, should be
C. had done, had been D. should do, had been
(3)I advised that he ______ to the hospital at once, but he insisted that he ______ quite well then.
A. was sent; felt B. be sent; was feeling
C. he sent; feel D. should be sent; should feel
6. ______ smoking, he would not have got cancer in the lung.
A. Was he given up B. Had he given up
C. Did he give D. If he gave up
【陷阱】容易误选 D.
【分析】正确答案应选B.之所以不能选D，是因为时态前后有矛盾。由于主句谓语是would not have got，这表明是对过去事实作出的假设，所以从句谓语应该是 had given up，而不是像D项那样用一般过去时。另外，当虚拟条件句中有 had, should, were 等词时，通常可以省略 if，并将 had, should, were 提前置于句首。又如：
Were they to cease advertising, prices would come down. = If they were to cease advertising, prices would come down. 如果他们停止做广告，价钱会降下来。
Had I been there, I would have filmed the occasion. = If I had been there, I would have filmed the occasion. 如果我在那里，我会把那场面拍摄下来了。
