文档介绍:高中定语从句语法总结
定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,有时也可以修饰部分或整个句子。
被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that, which, as。
关系副词有:when, where, why, how。
关系代词和关系副词放在先行词和定语从句之间,起连接作用,同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。
定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。
定语从句分为限制性定语从句和非限制性定语从句。
关系代词引导的定语从句
1) who, whom, that 这些词代替的先行词是人的名词或代词,在从句中所起作用如下:
Is he the man who/that wants to see you?
(who/that在从句中作主语)
He is the man whom/ that I saw yesterday.
(whom/that在从句中作宾语)
2) whose 用来指人或物,(只用作定语,若指物,它还可以同of which互换).
例如:
Please pass me the book whose (of which) cover is green.
3) which, that 它们所代替的'先行词是事物的名词或代词,在从句中可作主语、宾语等.
例如:
A prosperity which / that had never been seen before appears in the countryside.
(which / that在句中作宾语)
The package (which / that) you are carrying is about to come unwrapped.
(which / that在句中作宾语)
关系代词that和which 都可以指物,that 和Who 都可以指人,其用法区别:
不用that的情况:
a) 在引导非限定性定语从句时
(错)The tree, that is four hundred years old, is very famous here.
b) 介词后不能用
We depend on the land from which we get our food.
c) 多用who 的情况
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend.
②先行词为those, people 时
Those who were either fools or unfit for their offices could not see the cloth.
③先行词为all, anyone, ones, one 指人时
One who doesn't work hard will never succ
