大家不妨來看看小編推送的表語從句和定語從句的區別，希望給大家帶來幫助！
表語從句緊跟在聯絡動詞之後;而定語從句一般緊跟在先行詞之後;另外,兩種從句的`功能也大不相同,表語從句是對主語的描述,解釋或者身份的說明;而定語從句是對先行詞的修飾或者限制.
區別：定語從句所修飾的是名詞，表語從句是接在系動詞後面的做表語的成分，比如形容詞
例如:
That is why he was late for class that day.（表語從句）
That is the reason why he was late for class that day.（定語從句）
The reason why he was late for class that day was that there was a traffic jam on his way.（此句中why引導的是定語從句,修飾the reason;而 that是表語從句.
