九年級定語從句「推薦」

導語：九年級定語從句有哪些?以下是小編精心為大家整理的有關九年級定語從句示例，希望對大家有所幫助，歡迎閲讀。

　1定語的定義

定語是用來修飾或限定名詞的。定語一般位於被修飾名詞的周圍，在名詞前面或名詞後面。被修飾的詞有時也叫先行詞。定語可以是詞，短語或句子。

　2定語的位置

當定語是詞時通常是形容詞，放在所修飾名詞的前面。

如“一本有趣的書” an interesting book.

當定語是短語時通常用介詞短語，放在所修飾名詞的後面。

如 “教室裏的學生” the students in the classroom.

當定語是一個句子時，通常位於句子的後面，這個句子就叫定語從句。

如：I have a book which is interesting. 對比 I have an interesting book.

3定語從句中的關係代詞的用法

常見的`關係代詞：which / who / whom / that / whose

1.當先行詞為人時，可用關係代詞who / whom / that / whose

如：

He is the manwho thathelped me yesterday.(作主語）

He is the manwhomwho hat省略I helped yesterday.（作賓語）

He is the manwhosehouse is beautiful.（作定語）

2.當先行詞為物時，可用關係代詞which / that /whose

如：

I like the housewhich thathas new furniture. (作主語）

I like the housewhich that 省略you showed me around yesterday.

I like the housewhosefurniture is new.（作定語）

I like the housethe furniture of whichis new.

小結：關係代詞that 可用來修飾人或物，

who / whom只能用於修飾人，

which只能用於修飾物,

whose既可修飾人也可修飾物，但只能用於表所屬關係時。

4that 與 which 的用法區別

　1. 只能用 that 作為定語從句的關係代詞的情況

（1）當先行詞是 everything, anything, nothing （something 除外）, all, none, few, little, some 等不定代詞時，或當先行詞受every, any, all, some, no, little,few, much等詞修飾時。如：

Allthe booksthatare sold in the shop are very interesting.

（2）當先行詞被序數詞或形容詞最高級修飾時。如：

The firstmoviethatI watched was the Titanic.

This isthe bestbookthatI have read all my life.

（3）當先行詞被 the very, the only, the first / last 等修飾時 (當先行詞是人時，也可用 who,whom）如：

The old house isthe onlythingthathe owns.

She isthe onlyforeignerthat whowas invited to the party.

（4）當先行詞既有人又有物時。如：

I will never forgetthe persons and thingsthatare important to my life.

（5）當句子以who,which 等疑問詞開頭時。如：

Whois the manthatis standing in front of the room?

Whichis the roomthatyou live in?

2. 只能用which作為定語從句的關係代詞的情況

（1）當關系詞前面有介詞時，指物常用 which,指人常用whom.

The housewhich / that 省略we live in is very large.

（2）非限制性定語從句多用 which

　5關係副詞引導的定語從句
