新概念英语第二册 虚拟语气语法总结+专项训练（含答案）

《新概念英语第二册》语法总结 四、虚 拟 语 气 虚拟语气分三种情况来掌握： 1、虚拟条件句。[来源:Z&xx&k.Com] 2、名词性虚拟语气。 3、虚拟语气的其他用语。 一、虚拟条件句： 条件状语从句是非真实情况，在这种情况下要用虚拟语气。 1、条件从句与现在事实不一致，其句型为： If 主语＋过去时，主语＋should（could, would, 或might）＋动词原形，如： If I were you, I would study hard.

Were I to go to the moon one day, I would see it with my own eyes. Should it
