had done did/ were would do
之前 谓语动词 之后(1)
as if/as though (似乎是,好像是)的功能
① 引导表语从句,常和动词look / seem 连用:
She looks as if she were ten years younger.
她看上去好像年轻了10岁。
It seems as if our team is going to win.
好像我们队会赢。
② 引导方式状语从句:
He treated her as if she were his daughter.
他对待她好像是自己的女儿。(2)
as if (as though)可用于省略句中:as if 引导的从句常可省略主语和系动词,这样其后就只剩下名词、不定式、形容词(短语)、介词短语或分词(如文中例句)。
He acts as if (he were)a fool / mad.
他做事像个傻子 / 像疯了一样。
Tom raised his hands as if (he were going) to say something. 汤姆举起手好像要说什么。 根据汉语提示完成句子
(1) There are masses of dark clouds in the sky. It seems as if it is going to (将要) rain.
(2) He talked as if he had known (知晓) everything in the world. (1)is going to 从“天空中乌云密布”,我们就可以判断出天要下雨的可能性相当大,所以我们用陈述语气,因是客观推测的将来,所以答案是is going to。
