定语从句的语法【4篇】

定语从句也称为关系从句或形容词性从句,由关系代(who, whom, whose, which, that, as )或关系副词(when, where, why)等引导。关系词除了起引导作用外,还在从句中指代前面的先行词,并在从句中担任一定的成分。的小编精心为您带来了定语从句的语法【4篇】,如果对您有一些参考与帮助,请分享给最好的朋友。

all that 和 what 篇1

在定语从句中,许多人往往分不清all that 和what,what 实际上只引导名词性从句,它相当于all that 两个字,例如:

All that I know is that he has made up his mind to heave the country for a new place.

= What I know is that he has...

which和 as 篇2

在定语从句的非限制性定语中,which 和as 是容易混淆的。在很多情况下两者兼可互换,但在下列情况中不可互换:

(1)通常as 可以放在整句的句首,而which 只能在逗号之后,as 本身含有“正如”,as 在定语从句中既可是主语也可做宾语。

As appear from her paper, she has read widely in Romantic literature.

She is remarkable, as I have told you .

(2)which 在做非限制性定语从句关联词时可以无明确先行词,指前句整个的意思,如:She has married again, which surprises us.

定语从句的概念 篇3

在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。

关系副词的用法 篇4

(1)when指时间,其先行词表示时间,在句中作时间状语。例如:

This was the time when he arrived. 这是他到达的时间。

(2)where指地点,其先行词表示地点,在句中作地点状语。例如:

This is place where he works. 这是他工作的地点。

(3)why 指原因,其先行词是原因,起原因状语作用。例如:

Nobody knows the reason why he is often late for school. 没人知道他为什么上学总迟到。
