2017届高考英语一轮复习热点课件：第7节情态动词和虚拟语气高效语法

　　4. It is important that all of us ______ others when they are in trouble.

　　答案：

　　1. (should) go　

　　2. would　

　　3. had; helped

　　4. (should) help 1. ________ he followed my advice, he would have succeeded.

　　A. When

　　B. If

　　C. Had

　　D. Has 【分析】C　但容易误选B。不能选B，主要是因为时态前后有矛盾。由于主句谓语是would have succeeded，这表明是对过去事实作出的假设，所以从句谓语应该是 had followed，所以，如果选B，句子应该是 if he had followed my advice。但按英语语法，在此类表示虚拟条件的从句中，若有 had, should, were 等词，便可省略 if，而将 had, should, were 提前置于句首。 2. The man in prison insisted that he ________ nothing wrong and ________ set free.

　　A. had done; should be

　　B. should do; should be

　　C. had done; had been

　　D. should do; had been 【分析】A　此题容易误选B，想当然地认为 insist 后的从句谓语要用“should＋动词原形”这样的虚拟语气。事实上，insist后的从句谓语是否用“should＋动词原形”这样的虚拟语气，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。对上题而言，坐牢的这个人坚持了两点：一是没做错事，二是应该释放。很显然，在坐牢这个人看来，“没做错事”应该是事实，故用陈述语气；“被释放”还不是事实(因为他还在坐牢)，故用虚拟语气。所以此题的最佳答案应为A。 3. — It looks as if he were drunk.
