从句的连接词 I know what he is talking about. (从句中缺宾语,指物)
Do you know who he is? (从句中缺表语,指人)
Where he will go is unknown. (从句中缺地点状语)
I’m sure that they will come tomorrow. (从句中什么都不缺)
I don’t know which book I should choose. (从句中缺定语)
定义：充当主语功能的句子叫主语从句
That she was chosen made a great stir (轰动) in her school.
注意: ①it作形式主语的that-从句有以下四种不同的搭配关系：
It + be +形容词+ that-从句 It is necessary / important that…. …是有必要 / 重要的….
It + be + -ed 分词+ that-从句 It is universally acknowledged that../ It is known that…众所周知…
It + be +名词+ that-从句 It is common knowledge/ a fact that… ……是常识/事实
It +不及物动词+ that-分句 It happens that…碰巧.. / It occurs to sb.that… 突然想起……
名 主语从句 ②It 作形式主语和it引导强调句的比较
强调句： It is in the morning that the murder took place. (去掉该结构后,句子成分完整)
词 主语从句：It was a pity that you shouldn’t go to see the film. （在句子中做主语成分）
③whatever /whichever/ whoever引导主语从句的区别
Ⅰ Whatever 是what的强调形式表示“无论什么”相当于 anything that…
从 Whatever / Anything that she does is wrong.
Ⅱ whoever 是who的强调形式，表示‘无论谁’ 相当于anyone who….
句 ~ever Whoever / Anyone who walks around in such a heavy rain will catch a cold.
Ⅲ whichever ‘无论哪个;无论哪些’,既指人,又指物. 可修饰名词与of连用
