高考英语难点突破-虚拟语气课件.pptxVIP

虚拟语气 subjunctive mood Queenie 英语中有陈述语气，祈使语气，虚拟语气，疑问语气和感叹语气 首先，我们先来举例区分五种语气： 1、陈述语气 There is a house. 2、祈使语气 Go into house. 3、虚拟语气 If there were a house，I would go into it. 4、疑问语气 Is there a house？/ Where is the house? 5、感叹语气 How beautiful a house is！/ What a beautiful！ 条件状语从句 在以上情况中，其他四种语气基本表示真是的情况，只有虚拟语气表示一中假设的情况，If there were a house，I would go into it. 可以翻译为 ：如果有一座房子，我会进入它。 Def：虚拟语气： 1、是说话者用来表示假设，或难以实现的情况，并非客观存在的事实； 2、陈述的是一个条件，不一定是事实，甚至完全与事实相反； 3、表示主观愿望或者某种强烈的感情时，也可以用虚拟语气。 表示方式：谓语动词的特殊形式 内容 CONTENTS 在条件状语从句中的使用 01 条件状语从句 条件状语从句是由引导词if以及unless等词引导的状语从句。在英文中，“条件”是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”、“如果”。 注意：非真实条件句用虚拟语气 非真实条件句表示的是假设的或者实际可能性不大的情况，故采用虚拟语气 条件句虚拟式 从句 主句 例句 与现在事实相反 动词的过去式（be-were） would/ should/ might/ could+do If I were a bird, I would fly to you. 与过去事实相反 had+done would/ should/ might/ could+have done If we had started earlier, we should not missed the train. 与将来事实相反 should+do； 动词过去时； were to +do would/ should/ might/ could+do If teacher Li should have time tomorrow, we could ask him some question. 在虚拟语气中，有后退一个时态，注意be 动词的过去需要用were 省略if 的虚拟语气 从句中含有were/ should/ had 可将其放置于句首，省略if，用倒装 原句 一省二提 If I were you， I would take an umbrella. Were I you, I would take an umbrella. If it should happen, what would you do ? Should it happen, what would you do ? If he had recognized me, he would have come over. Had he recognized mehe would have come over. 在虚拟语气中，若有had/were/should等助动词，可将其提到句首，省略if变成为倒装句式，简称“一省二提” 例题巩固 1、 today，he would get there by Friday. A. would he leave B. was he leaving C. were he to leave D. If he leaves [考点解析] C 本题考察虚拟语气省略if 的用法，if 引导的非真实条件句中，如果从句中有were， should， had时，if 可以省略，但是句子必须用倒装结构。 2、 I you， I would go with him to the party. A. Was B. Had been C. Will be D. were [考点解析] D 本题考察虚拟语气省略if 的用法，if 引导的非真实条件句中，如果从句中有were， should， had时，if 可以省略，但是句子必须用倒装结构。 注意，在虚拟语气中，be 动词的过去式是were 含蓄条件句 采用暗含的方式表述假设的情况 例如通过介词短语表示 but for， without， otherwise等 例句 But for your advice, I could
