文档介绍：虚拟语气解析及练****与答案详解
虚拟语气
一、虚拟语气的运用
1、状语从句中的虚拟语气
（1）非真实条件句中的虚拟语气（if引导的条件句）
说明
从句谓语
主句谓语
例句
与现在事实相反
动词的过去式（be的过去式一般用were）
would/ should/ could/ might + 动词原形
If I were you, I should buy it.
如果我是你，我就买了它。
If I had time, I would study French.
如果我有时间，我会学****法语的。
If she knew English, she would not ask me for help.
如果她懂英语的话，她不会找我帮忙的。
与过去事实相反
had + 过去分词
would/ should/ could/ might + have + 过去分词
If you had got up earlier, you could have caught the train.
如果你早一点起床，就会赶上火车的。
If you had studied harder last term, you could have passed the exam. 如果上学期你努力学****的话，你考试就会及格了。
与将来事实相反
动词过去式（be用were）/should + 动词原形/were to + 动词原形
would/ should/ could/ might + 动词原形

如果明天天气好，我就去买东西。
省略if 的用法
有were, had, should等可省if，将were/had/should移至句首

如果我是你，我就买了它。
Had you studied harder last term, you could have passed the exam.
如果上学期你努力学****的话，你考试就会及格了。

含蓄条件句
在虚拟语气中，有时并没有明显的表示条件的句子，而是通过句子的逻辑关系或一些词、短语等暗示出来，如without, but for(要不是), otherwise(否则)
But for the English test, I would have gone home this week.
要不是英语测试，我这个礼拜就回家了。
Without war in the world, people would live a more happy ，人们生活得会更幸福。
He is ill. Otherwise he could e.
他病了，否则他会来的。
错综时间的条件句
主句与从句的动作发生在不同的时间，主句和从句的谓语动词的虚拟语气形式因时间不同而不同。
If you had listened to me, you wouldn’t be in such trouble now. （过去-----现在）
如果你听了我的话，你现在就不会有这样的麻烦了。
If I were you, I wouldn’t have missed the movie last night.
如果我是你，我就不会错过昨晚那部电影了。(现在-过去)
