参考:
主语从句
定义:在句子中担当主语的是一个从句,这个从句就叫做主语从句.
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、主语从句常用it作形式主语,一般常用句型为:
It is+{名词/形容词/过去分词}+主语从句例如:
It is still a question whether she will come or not.
It is strange that you should like him.
It is still unknown which team will win the match.
另外,还有一些比较多见的结构:
It turned out that……;
It has been proved that……;
It happened/occurred that……;
It is well-known that……等等
2.用it 作形式主语的结构
(1) It is +名词+that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+that从句
It is natural that… 很自然…
It is strange that… 奇怪的是…
(3) it +不及物动词+that从句
It seems that… 似乎…
It happened that… 碰巧…
(4) it is+过去分词+that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.
(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.
(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.
(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?
其中(4) it is+过去分词+that从句
It is reported that… 据报道…
It has been proved that… 已证实… 这里就是
和(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.
要注意区别 宾语从句是说that成分整个在句子中作宾语 而这个that做主语的

做主语
因为it's只是形式主语,他后面的从句或者是不定动词才是真正的主语。
这是八年级的重要知识。
