什么是表语呢？ 1. 她很漂亮。
She is very beautiful. 2. 这个故事听起来像是 真的。
The story sounds true. 3. 这些桔子很好吃。 These oranges taste good.
小结：放在系动词之后
注意： 表语常由名词、形容词、介词短语 、不定式、从句等来充当。
什么是表语从句呢？
The question is it. 表语从句
The question is who will do it.
表语从句放在连系动词之后，充 当复合句中的表语。

I t looks as if she is worried about her father’s disease. (与事实相符)
It looks as if it’s going to rain.
It was as though he were mad.
他似乎知道所有事情。 It seems as if he knows everything.
连接词：that / whether /as if /as though
It sounds as if/though somebody was knocking at the door. as if/as though引导的表语从句如果是事实，就用陈述语 气，如果与事实不符,就用虚拟语气

that
The fact is that our team has won the game.
1）that 在从句中不担任句子成分，无实际意义，一 般不能省略
2) 主 语 是 “ 建 议 ， 劝 说 ， 命 令 ” 的 名 词 ， 如 idea, suggestion, proposal, order, request, 表语从句 中谓语动词用“should + 动词原形”，should可省略
系动词的固定搭配:
come true, fall asleep, fall ill, go bad

why与 because引导表语从句时的区别
He was ill. Thawth’ys
注意：if 不能引导表语从句
连接词：that / whether /as if /as though
as if, as though 好像，似乎
常置于连系动词look, seem, sound, is, become等后面 It+连系动词（look/seem/appear……）+that/as if 从句 看起来似乎…
