if引导的非真实性条件状语从句即虚拟语气（最新整理）
if引导的非真实性条件状语从句即虚拟语气（最新整理）if 引导的非真实性条件状语从句即虚拟语气通过动词形式的变化来表示说话人对发生的动作或存在的状态所持的态度或看法的动词形式称为语气。
.英语中的语气分三种：陈述语气、祈使语气、虚拟语气。
虚拟语气表示说话人所说的话不是事实，而是一种祝愿，建议，与事实相反的假设或实际可能性不大的情况等（即非真实的假设）。
If 引导的条件状语从句分为真实和非真实条件句（虚拟条件句）。
真实条件句表示在假设的条件下，有可能实现的情况。
非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
If he doesn’t hurry up, he will miss the bus.( 真实条件状语)If he was free, he asked me to tell stories.（真实条件状语）If I were you, I would go at once.（非真实条件状语从句）If there was no air, people would die.（非真实条件状语从句）1）非真实条件句中虚拟语气的基本形式。

(事实上我不可能是你。
if引导的条件状语从句和虚拟语气的区别
1.if引导的条件状语从句所引导的是原因状语，可以是现实生活中已经出现的真实事件或有可能出现的事情，发生的可能性较大。
而虚拟语气所引导的往往是非真实的，对于过去，现在或将来的虚拟或推断，发生的可能性较小，或已经不可能发生了可以从2个角度去区分：1。
时态A，由if引导的条件状语从句通常都是主句为一般将来时，从句为一般现在时。
B，而在虚拟语气中，时态都是有很多，往往都是根据句子的含义判断，究竟是与现在，过去还是将来的事实相反。
2。
真实与非真实A，由if引导的条件状语从句一般都是真实的，只要所谓的条件成立，一定会成为事实B，但虚拟语气并非如此，if，既然是虚拟，就一定是非真实的，可以根据句意判断其是...条件状语从句连接词主要有 if, unless, as/so long as, on condition that 等。
if 引导的条件句有真实条件句和非真实条件句两种。
unless = if not. 例如：Let's go out for a walk unless you are too tired. 如果不太累，我们去散散步。
If you are not too tied, let's go out for a walk.You will be late ___ you leave immediately.A. unlessB. untilC. ifD. or答案A。
句意：除非你立即走，否则你就回迟到的。
可转化为 If you don't leave immediately, you will be late。
B、D句意不对，or表转折，句子如为 You leave immediately or you will be late.虚拟语气1）虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
虚拟语气在条件句中应用比较多。
2）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。
if引导的条件状语从句的用法
（3）假设
真的，或者有可能成为真的；
（二）假设将来，假设的条
将来
件是将来可能实现的。
1. if 非真实条件句（虚拟）——假设现在
（二）遵循的原则
should do
might+do
例 7 If I _____(be) a bird,I would fly to you right
状态，是正在玩球的意思，
所以此空填 is playing。
3. if 引导的真实条件状语从句——假设将来
例 3 If it _____(rain) tomorrow,we will stay at home.
解析：如果你不想受伤，
就不要玩刀。根据 Don’
t
play with the knife,主句是祈使句，所以从句为 if 引导
to the park.
he will take me to the park,主句用的一般将来时，而且
可以分析出，他哥哥现在还没有回，所以从句为 if 引
导的表将来的条件状语从句。根据“主将从现”的原
则，此空填 comes。
2. if 非真实条件句（虚拟）——假设过去
例8
Years ago if someone_____ (turn) round to

if 非真实条件句中的虚拟语气
一，if 非真实条件句中的虚拟语气1，if非真实条件句的基本用法由if一道的非真实条件句表示对现在，过去，将来的事实进行假设时，主句与从句谓语动词的形式可分为下列三种形式：1,The victim would have had a chance to survive if he had been taken to hospital in time.遇难者如果及时送到医院，他本来会有机会活下来的。
（与过去事实相反）2,If I knew his telephone number,I would tell you.如果我知道他的电话号码，我会告诉你。
（与现在事实相反）3,If there should be a heavy snow next Sunday,we would not go skating. 如果下周日下大雪的话，我们就不去滑冰了。
（表将来）2，省略if的虚拟条件句的用法在虚拟条件句中，如果从句中含有were，had或should 等词时，可将if省去，把were，had或should等提到主语之前，引起倒装。
如果居中没有were，had或should 等，则不能省略if，也不能倒装结构。
例如：Had it not been for the fact that she broke her leg,she might have passed the exam.要是她没有摔断腿，也许她会通过考试。
3,错综时间虚拟条件句有些时候，条件从句表示的动作和主句表示的动作发生在不同的时间，比如一个是过去发生的，一个是现在发生的。
这是，主句和从句的谓语动词要根据各自所指的不同时间选用适当的虚拟形式。
例如：If they had invited me ,I would go with them now.如果他们邀请过我，我现在就和他们一起走了。
二，介词或介词短语表示虚拟条件有些介词或介词短语隐含条件之义，其虚拟形式与if引导的非真实条件状语从句类似，需根据从句所用的时态，来选择主句的谓语形式。
if引导的非真实条件句的三种类型
"if引导的非真实条件句" 是指在现实情况中，条件句中的情况并不一定能够实现，或者实现的可能性很小。
这种句子通常用来表达与事实相反的情况，或者在虚拟环境中进行假设。
以下是 if 引导的非真实条件句的三种类型：1. 与现在事实相反或不可能发生的情况：这种类型的句子使用了一般现在时和一般过去时，但实际上这两种时态并不矛盾，因为它们只是表达了假设的情况。
例如：If I had enough money, I would buy a car. （如果我有很多钱，我会买车。
）If he were here, he would help us. （如果他在这里，他会帮助我们。
）2. 与过去事实相反或不可能发生的情况：这种类型的句子使用了过去完成时和过去进行时。
例如：If he had known your phone number, he would have called you. （如果他知道你的电话号码，他会打电话给你。
）If they had been here, they would have seen the movie. （如果他们在这里，他们会看到电影。
）3. 与将来事实相反或不可能发生的情况：这种类型的句子使用了过去将来时和过去将来进行时。
例如：If it were to rain tomorrow, we would stay at home. （如果明天下雨，我们会待在家里。
）If they were to come with us, we would plan to go out. （如果他们和我们一起去，我们会计划出去玩。
）。
