名词性从句一、定义：名词性从句相当于名词，可分别作主句的主语、表语、定语和同位语。因此，名词性从句可分为主语从句、 表语从句、宾语从句和同位语从句。

二、连接词：

三、用法：

连词：that, whether, if,as if 在从句中不充当成分 连接代词：who, whom, whose, what, which; 有词义，在从句中担任主语，表语，定语或宾语。 连接副词：when, where, why, how; 有词义，在从句中担任状语。 whatever, whoever…也可以引导

(1)主语从句——在复合句中用作主语的从句。 That I will win is certain. If 不能引导主语从句。 Whether we go together or separately doesn’t matter much. What you need is more experience. Where he has gone is not known yet. Why he failed the English exam wasn’t clear. Whatever was said here must be kept secret.

注意：当 that 引导主语从句时，习惯上多以 it 为形式主语， 而把主语从句后移。 e.g: It’s a shame that you can’t come to the party. It’s strange that he didn’t come yesterday.

可用 it 作形式主语的从句结构常有： 1. It’s a pity/shame/fact that...; It’s no wonder that..;(怪不得…) 2. It’s natural/possible/strange….; 3. It’s not known /decided that….; It’s said/reported that….; 4.

stay.b.介词后面的宾语从句不能用if. eg: I worry about whether I hurt

her feeling.

2).that在宾语从句中的省略与保留 a.在主+谓+it(形式宾语)+宾补+that 从句(真正宾语) 的句型中不省略. eg: We must make it clear that we mean what we say. b.由连词and连接的两个由that引导 的宾语从句中,第二个that 不省略. eg: He told me( that) he would come and that he would come on time.
