1、MODULE 5 第三课时 虚拟语气讲解 一、语气的分类 语气 mood 是一种动词形式,用以表示说话者的意图或态度;英语中的语气有三种：陈述语气、祈使语气和虚拟语气;1 陈述语气 indicative mood,表示所说的话是事实;2 祈使语气 imperative mood,表示所说的话是请求或命令;3 虚拟语气 subjunctive mood,表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等;二、虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句或称虚拟条件句两种;真实条件句所表示的假设

2、是可能发生或实现的,句中的从句与主句都用陈述语气;例如：If it doesnt rain tomorrow,I will go for a picnic.虚拟条件句所表示的假设则是不可能或不大可能发生或实现的,句中的从句与主句皆须用虚拟语气;从句 主句 与现在事实 相反的假设 If+主语+动词过去式be的过去式用 were 主语+should/would/might/could动词原形 与过去事实 相反的假设 If+主语+had+过去分词 主语+should/would/might/could+have 过去分词 与将来事实 相反的假设 If+主语+动词过去式 be 的过 去式用 were；

5、句和从句的谓语动词要依照假设的时间而定;If the weather had been finer,the crops would be growing still better.If you had followed the teachers advice,you wouldnt be in trouble.如果虚拟条件句的谓语部分有 were,had 和 should 时,可省略 if,这是应把were,had 和 should 放到从句主语前面去进行倒装;If I were you,I would give it up.Were I you,I would give it up.If i

10、gest,propose,recommend demand,require,request,desire 这些动词后面的宾语从句要使用虚拟语气用法;即从句中的动词要使用should+动词原形,或者将 should 省略;1 We suggested that Tom have a rest.2 He insisted that I shouldbe present.3 The king ordered that the prisoners be killed the next day.4 They requested that we should send them to work there

11、.注意若 suggest 作“表明,暗示”将时不用虚拟语气；insist 表示“坚持认为”讲,也不用虚拟语气;例如：1 His expression suggested he was angry.2 He insisted that he had nothing to do with it.以上动词相应的名词 order,advice,suggestion,proposal,demand,request构成的名词性从句包括主语从句,表语从句和同位语也要使用虚拟语气;即从句中的动词要使用 should+动词原形;6.用介词短语代替条件状语从句;常用的介词有：with、without 和 but
