2012届高考英语考前冲刺精品资料虚拟语气
是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等 (在宾语从句、表语从句、同位语从句)。
一、虚拟语气在条件句中
虚拟条件句 主句
与现在事实相反的假设 If+主语+动词的过去式（动词be用were) 主语+should,would,might,could＋动词原形
与过去相反的假设 If+主语+had +过去分词 主语＋should, would, might, could＋have done
与将来相反的假设 1、If+主语+动词过去式2、If+主语+were to+ 动词原形3、If+主语+should +动词原形 主语＋should, would might, could＋动词原形
eg:If I had time, I would attend the meeting.
If he had hurried ,he could have caught the train.
If I were to go abroad ,I would go to America.
More practice:
如果我是你，我就会努力学习．
如果我知道他的电话号码，我就给他打电话了．
如果明天下雨的话，我们会取消比赛．
使用虚拟条件句要注意的几点：
１． 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为：错综时间条件句“，动词的形式要根据它所表示的时间作出相应的调整．
If you had followed my advice , you would be better now.
如果你听我的建议，你现在就会痊愈了．
If you had studied hard before, you would be a college student now.
如果你努力学习的话，你现在就会是大学生了．
２．省略句
在条件句中，可省略 if，把were ,had, should 提到句首，变为倒装句式．
If I were at school again, I would study harder.
Were I at school again, I would study harder.
If you had come earlier, you would have met him.
