名词性从句与定语从句的区别

一．定义

在句中修饰名词的从句是定语从句。

在句中充当名词通常所充当的成分的从句是名词性从句。

Idon’tknowwhentheywillputtheplanintopractice.

（thetimewhen）

Ican’trememberthedaywhentheywillhavethemeeting.

Hetoldmethatanaccidenthappenedattheschoolgate.

Hetoldmeanaccidentthathappenedattheschoolgate.

定语从句有先行词。

名词性从句没有先行词。

1.看是否在从句中作成分。
