定語從句知識點分析
引導語:定語從句在句中做定語,修飾一個名詞或代詞,有時也可以修飾部分或整個句子。以下是本站小編分享給大家的定語從句知識點分析,歡迎閲讀!
被修飾的名詞,詞組或代詞即先行詞。定語從句通常出現在先行詞之後,由關係詞(關係代詞或關係副詞)引出。
關係代詞有:who, whom, whose, that, which, as。
關係副詞有:when, where, why, how。
關係代詞和關係副詞放在先行詞和定語從句之間,起連接作用,同時又可做定語從句的一個成分。當關系代詞做賓語時可以省略。
定語從句中的謂語動詞必須在人稱上和數量上和先行詞保持一致。
定語從句分為限制性定語從句和非限制性定語從句。

關係代詞引導的定語從句
1) who, whom, that 這些詞代替的先行詞是人的名詞或代詞,在從句中所起作用如下:
Is he the man who/that wants to see you?
(who/that在從句中作主語)
He is the man whom/ that I saw yesterday.
(whom/that在從句中作賓語)
2) whose 用來指人或物,(只用作定語,若指物,它還可以同of which互換).
例如:
Please pass me the book whose (of which) cover is green.
3) which, that 它們所代替的.先行詞是事物的名詞或代詞,在從句中可作主語、賓語等.
例如:
A prosperity which / that had never been seen before appears in the countryside.
(which / that在句中作賓語)
The package (which / that) you are carrying is about to come unwrapped.
(which / that在句中作賓語)
關係代詞that和which 都可以指物,that 和Who 都可以指人,其用法區別:

不用that的情況:
a) 在引導非限定性定語從句時
(錯)The tree, that is four hundred years old, is very famous here.
b) 介詞後不能用
We depend on the land from which we get our food.
c) 多用who 的情況
①關係代詞在從句中做主語
A friend who helps you in time of need is a real friend.
②先行詞為those, people 時
Those who were either fools or unfit for their offices could not see the cloth.
③先行詞為all, anyone, ones, one 指人時
One who doesn't work hard will never succeed in his work.
④在There be句型中There is a stranger who wants to see you.
⑤在被分隔的定語從句中
A new teacher will come tomorrow who will teach you German.
⑥在有兩個定語從句的句子中,其一用who,其二用that,但若先行詞後接兩個以上的並列定語從句時,後一個必須重複前一個關係代詞。
The student who was praised at the meeting is the monitor that is very modest and studies very hard.
There is a teacher who is always ready to help others and who enjoys what he does.
