问一下关于as if (as though)在虚拟语气中的用法
答
同学你好,我是来自新东方优能学习中心的老师陶然.
as if引导条件从句（即假设部分）,因此从句的时态有三种：
1、从句与主句动作同时：He looks as if he were an artist.——用过去时（am,is,are的过去时都是were）
2、从句动作先于主句动作：She speaks English so fluently as if she had studied English in Britain.——用过去完成时.
3、从句动作后于主句动作：He learns English so hard as if he would go to the U.S.A..——用过去将来时.
祝你取得好成绩.
