【高考英语语法】虚拟语气-主语从句中的虚拟语气!今天,伊顿教育自主招生辅导老师为大家整理了英语语法是主语从句中的虚拟语气,供大家浏览学习!
A.名词性从句中的虚拟语气
主句中的动词、名词、形容词如表示要求、建议、命令或愿望等含义,与其相关的名词性从句(主语从句、宾语从句、表语从句和同位语从句)中的谓语动词要用虚拟语气。
1.主语从句中的虚拟语气
主语从句通常用于"It is +形容词名词动词的-ed形式+ that ..."结构。主语从句中是否用虚拟语气取决于所用的形容词或动词的-ed形式,其谓语动词常用"should +动词原形"(美国英语常省略should,只用动词原形)。
①表示建议或命令
