A. 九年级英语语法聚焦翻译
一、定义：
在复合句中，修饰主句中的某一名词或代词的句子（从句）叫定语从句。定语从句所修饰的词叫先行词。定语从句作定语放在先行词的后面。
引导定语从句的词叫关系词，关系词有：关系代词that，which，who(宾格whom, 所有格whose)和关系副词when，where，why。关系代词或关系副词放在先行词和定语从句之间，既起连接作用，同时又作定语从句的一个成分。如：
The girl who is standing on the stage is my sister.
正站在台上的那个女孩是我的妹妹。（关系代词who在句中作主语）
I can’t find the book (that) I bought yesterday.
我找不到我昨天买的那本书。（关系代词that在句中作宾语，可省去）
Madam Curie was a great scientist whose name is known all over the world.
居里夫人是一位全世界闻名的伟大科学家。
二、用法：
（一）关系代词的用法：
（1）that指物，有时也指人，在从句中作主语或宾语。作主语不可省略，作宾语可省略。
which指物，不指人，在从句中作主语或宾语。作主语不可省略，作宾语可省略。如：

注意：
(一) which与that指物时可互相代替，但that比which更常见，尤其在口语中。但要注意that可用来指人，而which则不能指人。

⑦定语从句修饰的词为one, ones时，定语从句用that引导：

⑧当主句的主语是疑问词 who或 which来提问时，为了避免重复，用that引导定语从句：]
