缺少状语：用where（表地点）, when（表时间）, how（表方式）, why（表原因）。
3) 如不缺成份：主语从句、同位语从句用that引导，不能省略；表从、单个动词宾从可省略引导词that；介词宾从、第二个宾从，引导词that一般不省略；it作形式主语或宾语时，引导实际主从或宾从，一般that不省略；当主从、宾从本身为复合句时，引导词that不省略。
如：He told us sadly that what he had done secretly was dis covered by his parents.4) 含宾从的复合句中，主句和从句的时态保持一致，但如果从句中表示是客观现象，虽然主句是过去时态，从句仍用一般现在时。
5) 主语从句做主语，谓语动词用单数；如果由and 连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。

高中英语语法之 名词性从句(一)
名词性从句（一）●学而时习在英文中，名词或名词短语主要充当四种句子成分：主语、宾语、表语和同位语。
如果把句子当作名词来用，分别充当另一句话的主语、宾语、表语或同位语，于是便构成了四种从句：主语从句、宾语从句、表语从句和同位语从句。
因为这四种从句在本质上相当于名词的作用，所以将其统称为名词性从句。
●知识点精讲透析●考点一引导名词性从句的引导词●考点二主语从句1．作句子主语的从句叫主语从句。
主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。
that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
例如：Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：(1) It + be + 形容词（obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.）+ that从句。
如：It is certain that she will do well in her exam. 可以肯定她会考得很好。
It is probable that he told her everything. 很可能他把一切告诉了她。
