名词性从句(整理完整版)

名词性从句

一、定义：名词性从句在功能上相当于名词，是一个句子分别充当另一个句子的主语、

表语、宾语和同位语，由此被称为主语从句，表语从句，宾语从句和同位语从句。

辨别下列从句属于哪种名词性从句并分析：

1）Why they haven’t left yet is unclear.

2）It was good news that everyone got back safely.

3）Polly didn’t know which way she should go.

4）I’m interested in who that tall man is.

5）We all thought it good news that the fog had finally gone.

6）My question is whether Polly can find her way home.

7）The fact that Polly didn’t ask for the man’s name is a pity.

总结：名词性从句主要由陈述句、一般疑问句、特殊疑问句充当。

1）陈述句充当名词性从句时，由that引导；2）一般疑问句充当名词性从句时，由if或whether 引导从句；3）特殊疑问句充当名词性从句时，由疑问词本身做连词引导从句。4）名词性从句的语序应使用陈述句语序，不可用一般问句语序。
