as if有几下几种用法:
1、as if后接表语从句。
当as if后接表语从句中,其通常用于“It loos/seems as if…”的句型中,表示“看起来似乎……”。
例句:
It looks as if the pessimists are being proved right.
现在看来似乎悲观论者是正确的。
2、as if后接状语从句。
当as if后接状语从句,其含义为“似乎,就好像……”。当所描述的内容,是真实的或极有可能发生或存在的事实,从句通常用陈述语气,句子的谓语用look,seem,taste,smell,feel等。
例句如下:
It sounds as if they might have made a dreadful mistake
听起来他们似乎犯下了一个可怕的错误。
3、as if后从句也可以用虚拟语气。
as if的谓语动词有时也要使用虚拟语气,用来表示句子中所描述的情况与事实相反,或极少情况发生的情况。
例子:
I can remember our wedding as if it were yesterday.
我们的婚礼我记忆犹新,就像昨天一样。
as though这个短语的用法和as if类似,其含义为“好像,似乎”,其后也能接表语从句、状语从句和从句使用虚拟语气。
例如:
At one stage it looked as though they would win.
有一段时间,他们好像大有获胜的希望。
Mike looks as though he hasn"t had a square meal for weeks.
看迈克那样子,就好像几个星期没吃过一顿像样的饭了。
