高中英语语法专攻-《虚拟语气》
【考点1-用于条件句】
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甚至完全不可能发生的情况,故采用虚拟语气。
例如:If he doesn't hurry up,he will miss the bus.如果他不快点,他将错过巴士。( 真实)
If he is free,he will ask me to tell stories.如果他有空,他会要求我讲故事。(真实)
If I were you,I would go at once.如果我是你,我马上就会去。(我不可能是你。非真实,虚拟语气,与现在事实相反)
If there were no air,people would die.如果没有空气,人就会死亡。(不可能没有空气。非真实,虚拟语气,与现在事实相反)
If I have time, I will go with them. 假若我有时间,我就同他们去。(陈述语气)
If I were you, I would go with them. 假若我是你,我就同他们去。(虚拟语气)

(事实:没有带钱)
