1. I forget where I read the article， or I _____ it to you now. A.
will show B. would show C. am going to show D. am showing 「陷阱」几个
干扰项均有可能误选。

    「分析」正确答案选B.根据上文的语境可知句中的 or 隐含有一个虚拟的条
件，即 or=if I didn't forget where I read the article （要是我没忘记我
在哪儿读过这篇文章的话——但事实上忘了）。

    2. "It looks as if he were drunk." "So it does. _____." A. He'd better
give up drinking B. He shouldn't have drunk so much C. Health is more
important than drink D. I wonder why he is always doing so「陷阱」几个
干扰项均有可能误选，主要是受句中 drunk一词的影响。

    「分析」最佳答案为D.关键信息是It looks as if he were drunk中的虚拟
语气，句子既然用了虚拟语气，也就是说，" 他喝醉了" 不是事实，只是他的言
行好像是醉了，所以此题的最佳答案是D.

    3. "Mary looks hot and dry." "So _____ you if you had so high a fever."
A. do B. are C. will D. would 「陷阱」容易误选A 或C.选A 者，认为前后两
句的动词性质应一致；选C 者，认为其后带有if条件状语从句，从语气上看，主
句应用将来时态。

    「分析」此题最佳答案为D.分析如下：（1 ）"so + 助动词 +主语" 是一个
很有用的结构，它表示" ……也一样" 时。如：He likes to watch TV， and so
do I. 他喜欢看电视，我也一样。

    When animals and plants disappear ， so will man. 当动植物消失的时
候，人类也会随之消失。

    （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C 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。
