1、 条件句中的用法
虚拟语气的条件句是用谓语动词的特殊形式来表现与现在、过去事实相反的情况或对将来发生的情况表示怀疑,和直陈语气条件句中的谓语动词形式以及表达的含义完全不同。虚拟语气条件句中所用的谓语动词的过去时、过去完成时、过去将来时等,只表示不同的虚拟语气,和直陈语气的过去时、过去完成时、过去将来时等毫无关系。
现将虚拟语气的各种具体形式和用法分述如下;
a. 表示与现在事实相反的情况
①形式

If I (we,you,he,she,it,they)+行为动词的过去式(be的过去式一般用were) I (we) should

they,it ) would
所有人称+might(could)+动词原形
