He has just arrive but he talks as if he knew all about it.为什么用knew?为什么不用know?是不是只有在主句的谓语动词是实意动词才用虚拟语气?谢谢了两位老师!

if后面带的从句分两种,一种是非真实条件句,从句中作为条件的事情在实际情况是根本不可能发生的,这时候就用虚拟语气,if所带的从句的谓语用一般过去式.比如:If I were you.不过如果作为过去事实的非真实条件从句,谓语就要用过去完成式了.
还有一种是真实条件句,从句的条件是真实存在的,就不用虚拟语气,谓语用一般现在时.
出现了as if ,表虚拟,实际上他并不懂这个,而他假装懂得。
在英语语法里,用一般过去式表示虚拟。
因为。。has 吧
as if = as though = (好像) = 引导副词子句*** 表示 (强烈假定)
He speaks as if he were a teacher.
He behaved as though nothing had happened.
主要子句---现在式---副词子句---假设用过去式
as if虚拟语气
