▪ 虚拟语气是一种特殊的动词形式,用来表 示说话人所说的话不是一个事实,而只是 一种愿望、假设、怀疑、建议、猜测、可 能或纯粹的空想等。
▪ 在英语中,虚拟语气是通过句子中谓语动词的特 殊形式来表示的。这又一次证明动词在英语中的 核心地位,又一次证明要学好英语语法,就要学 好英语动词。由于虚拟语气是通过句子中谓语动 词的特殊形式来表示的,因此,掌握虚拟语气中 所使用的各种谓语动词形式变化是掌握虚拟语气 的关键,这也是虚拟语气的难点。虚拟语气本身 也是英语语法的一个难点。学习虚拟语气的方法 是分别弄通虚拟语气的各种句型和结构,各个击 破。下面对虚拟语气在各种句式中的用法分别介 绍。

(But he doesn’t own it or probably doesn’t own it or we don’t know whether he owns it or not.)

英语句子中谓语动词的语气有三种:1. 直陈语气(The Indicative Mood)直陈语气用于直截了当地陈述事实、描述状态:He has published quite a number of essays this year .他今年已发表了好几篇论文。
2. 祈使语气(The Imperative Mood)祈使语气用于提出请求、命令、建议或是劝告等:Wait outside until you are asked . 请在外面等候,请你进再进去。
Let's just take a break, shall we ? 我们休息一会儿,好吗?3. 虚拟语气(The Subjunctive Mood)虚拟语气用于表示主观愿望和假设的虚拟情况。
虚拟语气不太顾及事实的存在,它表现出说话人的主观因素比较多。
所以说话人所讲的内容往往是与事实相反的;或是其实现的可能性微乎其微,甚至于没有实现的可能性。
当然,有时为了使说话的语气客气、缓和、委婉,也使用虚拟语气。
例如:I wish you were more careful .但愿你更细心一些。
If I had more money, I would buy a bigger apartment.我要是有再多一点钱,我就买一套更大一些房子。
Would you mind shutting the door ? 劳驾您把门关上。

如:If you had come here yesterday, you would have seen him. 如果你昨天来到这里,你就会看见他了。
2. 表示一种与目前事实相反的假设情况,条件状语从句中的谓语动词要用一般过去式(be动词常用were),而主句中的谓语动词则要用“would / should / could / might+动词原形”。
