There is no subjunctive mood in our life. Learning Plan ●

M6U3 Grammar and Usage (1st period)

---Yvonne Chan

【知识准备】

英语中的语气分为陈述语气(indicative mood)、祈使语气(imperative mood)、虚拟语气(subjunctive mood)三类。虚拟语气表示一种纯属假设的情况或主观愿望时(情况与事实相反或者不太可能成为事实)，动词需用一种特殊形式---虚拟语气。

Indicative mood--- You love me. Imperative mood--- Love me, please! Subjunctive mood--- If you loved me, I would love you more.

条件状语从句分类

条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设或实际可能性不大的情况，故采用虚拟语气。

eg：

1. If he doesn't hurry up, he will miss the bus. 2.If he is free, he will ask me to tell stories.

3.If I were you, I would go at once.

4.If there were no air, people would die. 以上四句中

和

是真实语气

；

和

是虚拟语气
