疯狂英语高三虚拟语气

1、虚拟语气学案学习目标：1.了解虚拟语气的用法及主从句的结构； 2.学会在语境中正确地使用虚拟语气。学习方法亦即学习过程：自学，梳理知识；小组学习 相互答疑解惑；讨论 展示问题，全班讨论；探究，通过选择题检验所学知识是否到位；能力升华 在完成句子中让所学的知识进行能力的提升。一 虚拟语气在条件状语从句中的用法 与现在事实相反条件从句主句一般过去时，be多用wereWould /should/could/might+动词原形与过去事实相反条件从句主句过去完成时(had done/been) Would /should/could/might+have done与将来事实相反条件从句主句if +主语

2、+动词过去时主语+would/should/might/could+动词原形 if +主语+were to +动词原形同上 if +主语+should+动词原形同上例句：If I were you, I would go at once . If it should rain tomorrow, we would not go camping .

4、, 可以把if省略，而把这些词提到句首.Were I you , I wouldnt do that .Had you come earlier , you would have seen him .四 用动词的过去时表示与现在或者将来事实相反，用动词的过去完成时表示与过去事实相反.1. 在wish引导的宾语从句中I wish I were as clever as you .I wish I had finished my homework yesterday .在wish后面所接的从句用would / could +动词原形表示与将来事实相反.I wish I could fly to t
