在句中充当主语的从句叫做主语从句。
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。

That he will win is certain.Whether he’ll jin us in the discussin is f great imprtance.
1. 从属连词：that：只起引导作用，本身无实际意义，不充当任何成分，但不能省略。whether：意为“是否”，不充当从句的任何成分。
2. 连接代词wh, what, which, whever, whatever, whichever引导主语从句，包含意思，并在从句中充当成分。
Wh will meet him is nt decided.What yu tld me just nw was really a surprise.Which class will win the ftball game is nt clear.Whever breaks the law shuld be punished.Whatever he says is f n imprtance. Whichever f yu cmes first will receive a prize.

WhatThatThat
注： what 与 that在引导主语从句时的区别
what 在从句中充当句子成分，如主语、宾语、表语，而that 则不然。
What that
What what
Where we will hld the basketball game tmrrw is nt imprtant.When she will be back is still a questin.Why he came here is nt knwn.Hw we can prtect the grain frm damp needs t be discussed.
3. 连接副词when, where, why, hw等引导主语从句，包含意思，并在从句中充当成分，不可省略。
为了避免句子头重脚轻，通常把形式主语it放在主语位置，真正主语置于句末。
(1)it作形式主语，从属连词that引导的从句作真正的主语。①It＋be＋形容词(bvius，true，natural，surprising，gd，wnderful，funny，pssible，likely，certain，prbable等)＋that从句。It isn't likely that I shuld accept such an ffer as that.我不可能接受像那样的帮助。②It＋be＋名词词组(n wnder，an hnr，a gd thing，a pity，n surprise等)＋that从句。It's n wnder that he didn't want t g.难怪他不想去。

根据语意缺什么补什么都不缺用that或whether

that 、what、 which区别
that 在从句中不作成分，只起连接作用，无意义；
what在从句中作主宾表或定语，“what 什么, 或所 …”
which在从句中作主宾表或定语，which“哪一个”有选择范围。
