12、r country knew first aid, many lives would be saved.10. I would rather you paid me now. 请改正下列句子中的错误。1. stayed (should) stay。order的宾语从句的谓语用“（should）+ 动词原形”的虚拟结构。 2. will go went。would rather后的宾语从句中，用过去时表示现在或将来要做的事情。 3. would have been would be。从句说的是过去，所以用过去完成时，而主句指的是现在，即现在的虚拟结果，所以用“would + 动词原形”。4. l
13、eave left/should leave。在“It is （high）time that ”句型中，从句的谓语动词一般用过去式或should+动词原形，should不可省。 5. can could。if only引出的句子要用虚拟语气,谓语动词用一般过去时表示目前的愿望。 6. didnt do hadnt done。wish后的宾语从句谓语用过去完成时，表示与过去事实相反的愿望。7. didnt help hadnt helped。主句用“would / should + have + 过去分词”，表示过去时间的虚拟条件从句要用过去完成时。 8. couldnt be couldnt
14、have been。句意：要不是你那么努力，工作就不会准时完成了。从but for（要不是）短语中的“great”可知，“你”已经付出了努力，是暗含的条件，所以后面句子相当于虚拟条件句的主句，而且与过去事实相反，应该用couldnt have been。. 单项选择。1. B。考查if条件的虚拟语气，与过去事实相反，条件句省略了if，把had提前。2. B。考查混合虚拟语气，根据at the age of seven可知从句为对过去的假设，须用过去完成时。3. B。虚拟条件句中含有were或had，should时， if可省,将were, had, should提到主语前面，从句是与将来事实相
15、反的假设，所以用should，实际上“you”也不会被解雇。而主句说明的事实，所以用了will。4. D。从上下文可知，说话人没有参加讲座，省略了从句“if I hadnt been busy”，主句与过去事实相反，因此选D。5. D。前句是省略了if的与过去事实相反的虚拟条件句，而由now可知主句与现在事实相反，所以用would be。6. B。从句子的后半部分“I would have gone to the concert last Sunday.”可知用了虚拟语气形式，所以前面用but for（要不是）引出相当于条件句的介词短语。In spite of 尽管；Because of 因为
16、；As for 就.而言。7. C。If only引出的句子是一个条件句，要用虚拟语气；从上文可知说话人后悔没有听从对方的建议，应该用与过去事实相反的虚拟语气。8. A。此句是混合虚拟条件句，前面是与过去事实相反的虚拟条件句，后面的结果句受now影响应该与现在事实相反，所以选A。9. B。句型“It is time that.”从句的谓语动词用一般过去时表示虚拟。10. C。从“He was very busy yesterday”可知，谈论的是过去的事，otherwise相当于“如果昨天不忙的话”，所以主句用would have done。11. D。“Without electricity
17、”相当于条件句，从today可知句子与现在事实相反，所以谓语动词用would be。句意：如果没有电，人类今天的生活会完全不同了。12. D。句意：如果他认真听老师讲课了，他现在就会知道问题的答案了。从句与过去事实相反，用had listened；主句与现在事实相反，用would+动词原形。13. A。前面的分句是与过去事实相反的主句形式，but引出了过去的事实，而省略了与过去事实相反的条件句“if I had known that.”。即：如果我知道你在等我，我早就来了，但是我不知道你正在等我。“不知道”是过去的事实，用didnt know。14. D。从if从句中可知谈论的是与过去的事实相反的假设，主句应该用would have done。所以选D。15. D。主句是与现在事实相反的虚拟语气，从而排除A、C；if it is not for. 要不是因为.，此短语用于虚拟语气，省略了if，is变成were提前。句意：如果不是因为那些云彩，你会很容易地看到空中的飞机。版权所有：高考资源网()
