虚拟语气
一、词的语气
指我们平常说的说话人说话的口气。（在英语中，语气除了指语调以外，最主要的是通过动词发生变化而表示不同语气）
英语中的语气分为三类：
陈述语气（用于陈述句、疑问句、感叹句）
祈使语气（用于祈使句）
虚拟语气（用于条件状语从句、宾语从句等）
二、虚拟语气
如果所说的不是事实，而是一种假设、愿望、建议或是一种实现不了的空想，就用虚拟语气。
三、虚拟语气在非真实条件状语从句中的用法
1、真实条件状语从句与非真实条件状语从句
eg 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）
2、虚拟语气在非真实条件状语从句中的用法及动词形式
① 表示与现在事实相反的情况
