1、虚拟语气虚拟语气表达一种过于主观、计划、想法的语气态度。它用于时态方面往往是正常时态再套一层过去时，表示所说的话与事实相反或实现的可能性极小，或表示愿望、请求及建议等。虚拟语气用于以下几个方面。一、 非真实的 If 条件句（即虚拟条件句）1、形式和用法1)对现在情况的虚拟假设：表示现在实际上并不存在的情况were 形式：If + 主语 + Ved， 主语 + should(would, could, might) + 动词原形2) 对过去情况的虚拟假设：表示过去实际上并没有发生或已经发生了的事情形式：If +主语 + had +过去分词，主语 + should(would, could, mi
2、ght) + have+过去分词3) 对将来情况的假设：表示将来实现可能性不大的虚拟情况should形式：If + 主语+ were to +动词原形，主语 + should(would, could, might) + 动词原形考点 1、与现在事实相反的虚拟（说明：带的为重要例句）1.

If the whole operation _ before hand, a great deal of time and money would have been lost.A. was not planned B. has not been planned C. had not been planned D. were not planned考点 4.虚拟条件句的倒装在 if 从句中
7、，如有 were、should 、had 这三词，则可省去 if，并将这三词置于句首进行倒装，但如有否定词则否定词 not 须留原位不能前置。1. Had he worked harder, he _ the exams. A. must have got through B. would have got through C. would get through D. could get through2. _ the work, he would do it some other way.A. Was he doing B. Were he to do C. If he does D. I

If it _ too much trouble, Id love a cup of tea.A. isnt B. wasnt C. werent D. hadnt been考点 5. 错综时间条件句：错综时间是只主句和从句的动作不是发生在同一时间， 这时，需要根据意思采用表示不用时间的东西形式。当 if 虚拟条件是与过去事实相反，则用过去完成时；主句表达的意思若同现在事实相反，则不能用 would have done 而视具体情况而定，注意主

14、由 with, without, but for 等介词组成或由 but that, if it were not for, or, otherwise 等连词引出，并且均表示对过去发生事情的虚拟。1._, we could not have finished the work on time.A. If they do not help us B.Was it not for their help C. Should they offer to help us D. But for their help2. He was holding a consultation with his stu

21、注意它与 only if 的区别。if only 与 supposed/supposing/what if 功能相同，在其谓语动词的正常时态套一层过去时即可。过去发生的事虚拟用过去完成时，现在发生的虚拟用过去时，将来的虚拟用过去将来时。supposed/supposing I accepted this offer 假如我接受这提议，你怎么办？If only you hadnt offend him then! 你当时没冒犯他就好了。1.
