虚拟语气
一、词的语气
指我们平常说的说话人说话的口气。(在英语中,语气除了指语调以外,最主要的是通过动词发生变化而表示不同语气)
英语中的语气分为三类:
陈述语气(用于陈述句、疑问句、感叹句)
祈使语气(用于祈使句)
虚拟语气(用于条件状语从句、宾语从句等)
二、虚拟语气
如果所说的不是事实,而是一种假设、愿望、建议或是一种实现不了的空想,就用虚拟语气。
三、虚拟语气在非真实条件状语从句中的用法
1、真实条件状语从句与非真实条件状语从句
eg If he doesn’t hurry up, he will miss the bus.( 真实条件状语)
If he was free, he asked me to tell stories.(真实条件状语)
If I were you, I would go at once.(非真实条件状语从句)
If there was no air, people would die.(非真实条件状语从句)
2、虚拟语气在非真实条件状语从句中的用法及动词形式
① 表示与现在事实相反的情况
(条件)从句谓语动词形式 主句谓语动词形式
谓语动词用过去式(be用were) should/would/could/might+动词原形

如果我带钱了,我就会借给你些。(事实:没带钱)
If he studied harder, he might pass the exam.如果他在努力些,就能通过考试了。(事实:学习不用功)
②表示与过去事实相反的情况

如果我早到那儿,我就会见到她。(事实:去晚了)
If he had taken my advice, he would not have made such a mistake.
如果他听我的劝告的话,就不会犯这样的错误了。(事实:没有听我的话)
③表示对将来情况的主观推测(可能相反或可能性很小)
从句 例句 主句
① were
If+主语 ② did
③were to do
(①通常与一个表示时间状语连用)其 中were to do可能性最小,
should+动词原形。 If it rained tomorrow our picnic
would be put off.
万一那天下雨,我们的郊游
就推迟。
should/would do might
主句 /could
eg: If he would come here tomorrow, I should/would talk to him.
如果他哪天来这儿的话,我就跟他谈谈。(事实:来的可能性很小)

1、虚拟语气用在wish 后的宾语从句
a、表示与现在事实相反的愿望,谓语动词用过去式

c、表示将来难以实现的愿望

eg: I wish I should have a chance again.很难再有这样的机会了。(事实:很难再有这样的机会了)
②虚拟语气用在suggest(建议)、insist(坚持)、demand(要求)、order(命令)等动词后的宾语从句中。
在这种用法中,无论主句谓语动词为何种时态,从句的谓语动词都用:“should + 动
词原形”或只用“动词原形”。
如 He suggested
He insisted
He demand that we (should) take the teacher’s advice
