初中定语从句名师讲解

　　定语从句就是在句子中充当定语成分的从句，分享了初中定语从句的名师讲解，一起来看看吧！

　　一、定语从句的概念

　　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。

　　The man who / that I saw at the school gate yesterday is my English teacher.

　　先行词定语从句

　　昨天我在校门口看见的那个人是我的英语老师。

　　二、定语从句的关系词

　　引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that, which, who(宾格whom，所有格whose)等，关系副词where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。

　　① I am waiting for the boy who /that is wearing a red coat. （关系代词作主语）

　　先行词关系代词

　　我正在等穿着红色外套的那个男孩。

　　② The dictionary that / which my sister gave me last Sunday is very expensive.

　　三、关系代词的用法

　　宾语时可省略。例如：

　　① Mary likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。(that作主语)

　　(that作宾语)

　　② The film (which) we saw last night was wonderful.

　　② Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?

　　which—指物，作主语，不能省略；作宾语，可以省略。

　　who—指人，作主语，不能省略；作宾语（常用whom），可以省略。

　　注：当关系代词在定语从句中作主语时，定语从句的谓语动词形式由先行词定。

　　注意——

　　(1) 当定语从句中含有介词，介词放在句末时，who, that, which可省略，但介词在关系代词前时，只能用“介词+ which/whom”结构。例如：

　　① This is the house in which we lived last year. 这是我们去年居住的`房子。

　　This is the person whom you are looking for. 这就是你要找的那个人。

　　(3) that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如：

　　The city that she lives in is very far away. 她居住的城市非常远。
