名词性从句又可称作为宾语从句，就是在复合句中作宾语的名词性从句，它通常放在主句谓语动词（及物动词）或介词之后。
1.作动词的宾语
1）由that引导的宾语从句（that 通常可以省略）,例如：
I heard that be joined the army.（that可以省略）
2）由what, whether (if) 引导的宾语从句，例如：
She did not know what had happened.
I wonder whether you can change this note for me.
3）动词＋间接宾语＋宾语从句。例如：
She told me that she would accept my invitation.

2.作介词的宾语 例如：
Our success depends upon how well we can cooperate with one another.

3.作形容词的宾语 例如：
I am afraid (that) I’ve made a mistake.
That 引导的从句常跟在下列形容词后作宾语： Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。

4.It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如：
We heard it that she would get married next month..

5.有些动词后边不能直接跟that 从句，这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。例如： I admire their winning the match. （此句中admire后面不能加that）

6.有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的这类词有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如： 正：He impressed the manager as an honest man.
误：He impressed the manager that he was an honest man.

7.若主句谓语动词为Think, consider, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式，这就是否定转移。例如：
I don’t think this dress fits you well.（我认为这件衣服不适合你穿。）
