虚拟语气归纳总结.pptVIP

* Part2 语法专题 考点7 虚拟语气 对虚拟语气的考查在湖南高考中主要出现在单项填空部分。 　1.主要考查的知识点： 　(1)在状语从句和名词性从句中虚拟语气的用法 　(2)含蓄虚拟语气 　复习重点： 　(1)掌握虚拟语气的基本概念及用法。 　(2)在条件句中省略if的虚拟语气。 　(3)意义上不是虚拟语气，但必须使用虚拟语气的情况。 　2. 如何应对虚拟语气的考查 　解题时，首先要确定题干句子表示的句意为真实的还是虚拟的，来决定是否该用虚拟语气。带有状语从句的复合句应重点看从句，根据从句句意所表达的信息来判断是否该用虚拟。虚拟语气确定后要明确是对现在、过去还是对将来的虚拟，从而确定虚拟语气的形式。 (2009·福建)But for the help of my English teacher, I ______ the first prize in the English Writing Competition. would not win B. would not have won C. would win D. would have won 思路点拨：分析题干，根据But for the help of my English teacher(要不是我的英语老师)，可知该句为虚拟语气。整句语意为：要不是英语老师的帮助，我就赢不了英语写作比赛一等奖。“赢得一等奖”是已经过去的事情了，所以此处表达的是对过去的虚拟，谓语该用would not have done的形式。故判断空格处应该选B。 熟 读 深 思 1. 状语从句中的虚拟语气 (1) If I __had__(have) time, I would go there.
