如何講解定語從句

想要講解定語從句嗎？那麼應該從哪些方面進行講解呢？下面就和小編一起來看看吧。

一、定義：在複合句中，修飾某一名詞或代詞的從句叫做定語從句。 定語 定語用來限定、修飾名詞或代詞的，是對名詞或代詞起修飾、限定作用的詞、短語(動詞不定式短語、動名詞短語和分詞短語)或句子，漢語中常用‘……的’表示。主要由形容詞擔任，此外，名詞，代詞，數詞，分詞，副詞，不定式以及介詞短語也可以來擔任，也可以由一個句子來擔任。 單詞作定語時通常放在它所修飾的詞之前，作前置定語。短語和從句作定語時則放在所修飾的詞之後，作後置定語。定語從句是指在一個句子中作定語的句子，定語從句要放在所修飾的詞後。如：

1) The man who lives next to us is a policeman.

2) You must do everything that I do.上面兩句中的man和everything是定語從句所修飾的詞，叫先行詞，定語從句放在先行詞的後面。

引導定語從句的詞有關係代詞that, which, who(賓格whom, 所有格whose)和關係副詞where, when、why關係詞常有三個作用：

1、引導定語從句

2、代替先行詞

3、在定語從句中擔當一個成分

　二、關係代詞引導的'定語從句

1、who指人，在從句中做主語

(1)The boys who are playing football are from Class One.

(2)Yesterday I helped an old man who lost his way.

2.、whom指人，在定語從句中充當賓語，常可省略。

(1) Mr. Liu is the person (whom) you talked about.注意：關係代詞whom在口語和非正式語體中常用who代替，可省略。

(2) The man who/whom you met just now is my friend.

3、which指物，在定語從句中做主語或者賓語，做賓語時可省略

(1) Football is a game which is liked by most boys. ( which 在句子中做主語)

(2) This is the pen (which) he bought yesterday. ( which 在句子中做賓語)

三、定語從句的結構：在複合句中，修飾某個名詞或代詞的句子（做這個名詞或代詞的定語）叫定語從句，定語從句一般放在被修飾的名詞或代詞後面，被修飾的名詞或代詞叫做定語從句的先行詞，它與定語從句之間要有一個詞連接，這個詞指代先行詞的內容叫做關係詞（關係代詞或關係副詞：that, which, who, whose, when, where, why）。先行詞在定語從句中充當主語，賓語，時間，地點，原因狀語。

結構：先行詞+關係詞+定語從句。
