虚拟语气

在英语文法中有三种语气，即直述式语气(Indicative Mood)、祈使语气 (Imperative Mood)和虚拟语气(Subjective Mood)，其中前两种我们早已熟悉了，这里则不多谈了，如： How beautiful she is! 则是直述式语气，而Hurry up! Don't hurry up 则是祈使语气。我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实，假想为事实予以表述。这样的动词结构称为虚拟语气。它主要有三种形式，即与现在事实相反的假设，与过去事实相反的假设，与将来事实相反的假设。它们具体结构如表８－７。

1.（2011江苏34） —I left my handbag on the train, but luckily someone gave it to a railway official.

— How unbelievable to get it back! I mean, someone it.

A. will have stolen B. might have stolen C. should have stolen D. must have stolen 解析：本题考查情态动词。句意：“我把包忘在车上了，幸运的是，失而复得了”。“很难相信会有这种事发生，我的意思是，很有可能是会被别人偷走的。” will have stolen是将来完成时，表示到将来某个时间，某件事一定会发生，显然不符合语境; should have stolen表示“本该最某事”，也不符合意思; must have stolen表示“一定做了某事”，显然错误。这里应该选用might have stolen表示说话者觉得包落在火车上，很有可能是会被

虚拟条件句主要有三种结构：

1)表示与现在情况相反：主句谓语用“would / could / might +动词原形”，从句谓语用“动词的一般过去时”（动词be的过去式一律用were）。

语法结构：虚拟语气

虚拟语气是英语三级考试的必考知识点之一，也是体现英汉语言习惯区别的一个语法现象。在汉语里表示假设虚拟的情况常用一些虚词来表示，例如“假设”、“如果”等等；而英文中表示虚拟的情况不但有虚词的提示，谓语动词也要相应的变化。 虚拟语气的基本作用是：

1. 表达假设的情况，与事实相反；

2. 表达异想天开很难实现的愿望；

3. 表达建议、命令、劝告等语气。

本节重在讲解if引导的虚拟条件句， 含蓄条件句，特殊结构中的虚拟语气，以及should+动词原形的用法。
