13、现在的虚拟结果，所以用“would + 动词原形” 。4. leave 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
14、拟条件从句要用过去完成时。 8. couldnt be couldnt 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
15、，should 时， if 可省,将 were, had, should 提到主语前面，从句是与将来事实相反的假设，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
16、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；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，ot
17、herwise 相当于“如果昨天不忙的话” ，所以主句用 would have done。11. D。 “Without electricity”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：学优高考网()
