在复合句中起名词作用的从 句叫做名词性从句。 名词性从句 主语从句 表语从句 宾语从句 同位语从句

that, whether, if, because as if /as though(不充当 从句的任何成分) 连接词

how, why, when, where however, wherever 连接副词

who, whom, whose, which, what, whatever

连接代词引导名词性从句的关联词 在名词性从句中一律用陈述句 的语序,即使从句表达的是疑 问含义。

The problem is what he has done


to the little boy问题是他对那个小男孩做了些 什么。 1. 主语从句

在句中作主语的句子叫主语从句。 主语从句通常由附属连词that, whether 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在从句中无词义,只起连接 作用;连接代词和连接副词在 句中既保存自己的疑问含义、 又起连接作用,在从句中充当 成分。

What he wants to tell us is not clear他要跟我们说什么,还不清楚。 Who will win the match is still unknownWhere the English evening will be held has not yet been

announcedThat he stole a bike was true单个的主语从句作主语时,谓 语动词用单数形式。如果是两 个或两个以上的主语从句作主


语,谓语动词那么用复数形式。 Where and when he was born has

not been foundWhen the person was murdered and why he was murdered are still unknown有时为防止句子头重脚轻,常 用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。主句的谓语动词一般用 单数形式。常用句型如下: 1)It + be + 名词 + that从句 2)It + be + 形容词 + that从句

3)It + be + 动词的过去分词 + that从句 4)It + 不及物动词 + that 从句 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。
