英语中的虚拟语气
虚拟语气是说话者用来表示假设,或难以实现的情况,而非客观存在的事实,所陈述的是一个条件,不一定是事实,甚至完全与事实相反。此外如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。虚拟语气通过谓语动词的特殊形式来表示。
中文名: 虚拟语气
外文名: Subjunctive Mood
意义: 说话人的主观愿望或非真实情况,而不表示客观存在的事实。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如:
If I were a bird,I would be able to fly in the air.
如果我是一只小鸟,我就能在空中飞行。
I wish I could pass the examination.
我希望我能通过考试。
在表示假想的虚假的、与事实相反的或难以实现的情况时用虚拟语气,表示主观愿望或某种强烈情感时,也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法,愿望,假想,猜测,怀疑或建议,而不是根据客观实际,就用虚拟语气。
虚拟语气有三种基本结构,分别是:对过去的虚拟,对现在的虚拟和对将来的虚拟
