⑧ 九年級上冊英語有哪些重要語法阿
——定語從句（the Attributive Clause）
Name: ______________ Class: ______________ No.:______________
一、定義：
在復合句中，修飾主句中的某一名詞或代詞的句子（從句）叫定語從句。定語從句所修飾的詞叫先行詞。定語從句作定語放在先行詞的後面。
引導定語從句的詞叫關系詞，關系詞有：關系代詞that，which，who(賓格whom, 所有格whose)和關系副詞when，where，why。關系代詞或關系副詞放在先行詞和定語從句之間，既起連接作用，同時又作定語從句的一個成分。如：
The girl who is standing on the stage is my sister.
正站在台上的那個女孩是我的妹妹。（關系代詞who在句中作主語）
I can』t find the book (that) I bought yesterday.
我找不到我昨天買的那本書。（關系代詞that在句中作賓語，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聞名的偉大科學家。
二、用法：
（一）關系代詞的用法：
（1）that指物，有時也指人，在從句中作主語或賓語。作主語不可省略，作賓語可省略。
which指物，不指人，在從句中作主語或賓語。作主語不可省略，作賓語可省略。如：
His father works in a factory that/ which makes TV set. （作主語，指物）
The coat (that/ which) I put on the desk is black. （作賓語，可省去）
The books (that/ which) they bought were written by me. （作賓語，可省去）
注意：
(一) which與that指物時可互相代替，但that比which更常見，尤其在口語中。但要注意that可用來指人，而which則不能指人。
只能用that不能用which引導的定語從句：
①定語從句所修飾的詞，同時又被形容詞最高級修飾時，定語從句只能用that引導；
