高考英语重点知识点大全
主语从句
主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较。
It
作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。
例如：
It is a pity that you didn’t go to see the film.
It doesn’t interest me whether you succeed or not.
It is in the morning that the murder took place.
It is John that broke the window.
2. 用it 作形式主语的结构。
(1) It is +名词+从句
It is a fact that …事实是…
It is an honor that …非常荣幸
It is common knowledge that …是常识
(2) it is +形容词+从句
It is natural that…很自然…
It is strange that…奇怪的是…
(3) it is +不及物动词+从句
It seems that…似乎…
It happened that…碰巧…
(4) it +过去分词+从句
It is reported that…据报道…
It has been proved that…已证实…
3. 主语从句不可位于句首的五种情况。
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said ，(reported) …结构中的主语从句不可提前。
例如：
It is said that President Jingo will visit our school next week. (right)
That President Jiang will visit our school next week is said. (wrong)
(3) It happens…，It occurs…结构中的主语从句不可提前。
例如：
It occurred to him that he failed in the examination. (right) That he failed in the examination occurred to him. (wrong) (4) It doesn’t matter how/whether …结构中的主语从句不可提前。
例如：
It doesn’t matter whether he is wrong or not. (right) Whether he is wrong or not doesn’t matter. (wrong)
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。
例如：
Is it likely that it will rain in the evening? (right)
Is that will rain in the evening likely? (wrong)
4. What 与that 在引导主语从句时的区别。
What 引导主语从句时在句时在从句中充当句子成分，如主语.宾语.表语，而that 则不然。
例如：
1) What you said yesterday is right.
2) That she is still alive is a consolation.
