主语从句在复合句中充当主句的主语。引导主语从句的词有：
从属连词：that, whether(通常不用if);
That she will come to our party is certain.
Whether it is true remains a question.
连接代词：who, whose, whom, what, which,whoever, whichever, whatever;

连接副词：when, where, why, how等。

注意：（1）从属连词if通常不能用来引导主语从句，应该用whether(or not)；
(2) 以wh-连接代词和连接副词引导的主语从句采用陈述句语序；
(3) 以that 为从属连词引导的主语从句如位于句末，在非正式场合，that可省略；如：It is clear rain will fall this evening.(rain前省去了that)
2.it作形式主语结构
主语从句位于句首常显得笨重，因此常将它移至句末，句首用it作形式主语。
1） that 从句作主语时，为了使句子平衡，常用it 作形式主语。
It is certain that he will come here. 他会来这里这是很确定的。
结构：it+be+adj.+主从
It is wonderful that we won the competition.
结构：it+be+adj.+主从
2）It was a pity that you failed the exam.
结构：it+be+n.+主从
3）It happened that I met her in the street.
结构：it+appear/happen/seem/matter等不及物动词+主从
4） It is said that she married last year.
结构：it+be+过去分词+主从
3.it作形式主语情况
（1）以that引导的主语从句通常用it作形式主语；
（2）以wh-引导的主语从句一般放在句首，也可用it作形式主语；
（3）全句如果是一般疑问句，则多用it作形式主语，如：
Is it probable that she will go there today?
（4）全句如果是感叹句，则必须用it作形式主语；

2)谓语动词think/thought 与that从句之间有插入的词语，that也不能省：

3) 宾语从句并列时，第一个that可以省略，第二个不能省略；
She said (that) she couldn’t tell me and that I wouldn’t understand.
4)if 和whether都可以引导宾语从句，但if后不能跟or not,whether后可以和or not连用；
5）动词doubt引导的宾语从句，肯定句用if/whether, 否定句或疑问句用that
6）that不能充当介词宾语，偶尔可作except，in的宾语。其他介词后，需要用that从句作宾语时，常用it作形式宾语。

Step7:课后反思



将主语位置换成一个句子，该句变成了一个含有主语从句的句子。

将宾语位置换成一个句子，该句变成了一个含有宾语从句的句子。

将表语位置换成一个句子，该句变成了一个含有表语从句的句子。

利用一个句子对主句的主语进行解释说明，就构成了一个同位语从句。
