新概念一定語從句
定語從句的概念在復(fù)合句中,修飾某一名詞或代詞的從句叫定語從句.被修飾的名詞或代詞叫先行詞。下面是小編整理的新概念一定語從句，歡迎大家閱讀參考。
篇一：新概念一定語從句
一、什么是定語(Attributive) :
a loyal friend 形容詞作定語
a woman teacher 名詞作定語
a girl with long hair 介詞短語作后置定語
falling / fallen leaves 分詞作定語
定語從句在句中相當(dāng)于一個(gè)定語的成分起修飾的作用。
二、定語從句的構(gòu)成：
1)which/that
a. Annawas wearing a hat.
b. Itwas too dirty.
定從： Annawas wearing a hat which/that was too dirty. (主語)
安娜戴了一頂很臟的帽子。
a. The hat was too dirty.
b. Anna was wearing a hat
定從： The hat that/ which Anna was wearing was too dirty.(賓語)
安娜戴著的那頂帽子太臟了。
2). who/whom
a. I meta boy.
b. Theboy can speak three languages.
定從： I met a boy who can speak three languages. (主語)
我見到了一個(gè)能說三種語言的男孩兒。
a. Theboy can speak three languages.
b. I met a boy.
定從：The boy whom/ who I met can speak three languages. (賓語)
我見到的男孩兒能說三種語言。
3. whose
a. We saw some people.
b. Their arms had broken.
定從： We saw some people whose arms had broken.
我們看見了一些手臂受了傷的人。
a. The desk belongs to Mary.
b. The leg of the desk is broken.
定從： The deskwhose leg is broken belongs to Mary.
腿壞了的桌子屬于瑪利。
三、只能使用關(guān)系代詞that的幾種情況。
1. 先行詞為all, little, few,much, nothing, something, anything, everything等不定代詞時(shí)
e.g.There is nothing that I can say
2. 先行詞被 all, each, few,much, every, no, some, any 等詞修飾時(shí)
e.g. I have few books that you needed
3. 先行詞既有人又有物時(shí)
e.g. He talked about the teachers and schools that he liked
4.先行詞被序數(shù)詞或形容詞最高級(jí)修飾時(shí)
e.g. This is the best composition that I have read.
5. 先行詞被the only, the very,the last 等修飾時(shí)
e.g. This is the very man that I am looking for.
6. 主句是以who或which開頭的疑問句時(shí)
e.g. Who is the man that is holding Mary’s hand?
四、非限定性定語從句 Non-restrictive Attributive Clause
1. “位置形式”：緊接先行詞，不用標(biāo)點(diǎn)分割
e.g. I want to buy the house which has agarden.
2. 用逗號(hào)與主句隔開，修飾“主句全句或部分內(nèi)容”，可置句末，中，首。
e.g. I want to buy the house, which has agarden.
The earth is round, which is known to all
As is known to all, the earth is round.
3. “先行詞”
限定性： n. / n. phrase
e.g. He wears a red shirt which makes himlike a girl.
非限定性：1). n. / n. phrase
2). the sentence
e.g. He wears a red shirt, which makes himlike a girl.
“關(guān)系詞的用法”
限定性：1).關(guān)系代詞作從句賓語時(shí)可省
2). that可替who, whom, which(口)
e.g. This is the book( which/that) I boughtyesterday.
非限定性：1).關(guān)系詞不能用that
2).不能替換，不能省(which, as)
e.g. I like the book, which I bought yesterday
Do you know Tom, whom we talked about?
She has to work on Sundays,which she doesn’t like.
篇二：二新概念一定語從句
一、定義
用來修飾句子中的名詞或代詞或其短語的從句，就叫做定語從句。其實(shí)，就是拿句子來做名詞、代詞或是其短語的定語。如：
It's a book.
I bought the book yesterday.以上兩句話中，都有book一詞，所以可以用定語從句把兩句話連起來。即：
It's the book that I bought yesterday.這句話中that引導(dǎo)的I bought yesterday就是一個(gè)定語從句，用來修飾the book。
二、兩個(gè)概念
要想學(xué)好定語從句，得先弄清楚兩個(gè)基本概念，即：先行詞和關(guān)系詞。
(一)先行詞
所謂先行詞，就是指定語從句所修飾的成分。這個(gè)名稱倒是挺形象的，為什么?因?yàn)橄刃性~永遠(yuǎn)出現(xiàn)在定語從句的前面，總是先走一步的，呵呵!
(二)關(guān)系詞
所謂關(guān)系詞，就是指用來連接定語從句的詞語。關(guān)系詞可以分為關(guān)系代詞和關(guān)系副詞。需要注意的是，關(guān)系代詞或關(guān)系副詞都要在從句中充當(dāng)成分的，所以是不可或缺的，盡管當(dāng)關(guān)系代詞在從句中作賓語時(shí)，經(jīng)常可以省略(本文會(huì)繼續(xù)講到這個(gè)情況)。
我們?cè)趤砜匆幌略诘谝还?jié)里出現(xiàn)的句子：
It's the book that I bought yesterday.句中的'the book就是先行詞，被后面的從句I bought yesterday所修飾。而that就是關(guān)系代詞，用來連接I bought yesterday，同時(shí)又在從句作bought的賓語，而且可以省略。
定語從句的學(xué)習(xí)，其實(shí)就是有關(guān)根據(jù)先行詞的特點(diǎn)選擇合適的關(guān)系詞的學(xué)習(xí)。
三、分類
按照定語從句與先行詞的關(guān)系緊密與否，可以分為限定性定語從句和非限定性定語從句。
(一)限定性定語從句
限定性定語從句對(duì)先行詞起著修飾限定作用，是不可或缺的。如：
These are the apples that/which they sent us two days ago.
(二)非限定性定語從句
非限定性定語從句對(duì)先行詞起著補(bǔ)充說明作用，可要可不要。非限定性定語從句都會(huì)被逗號(hào)與先行詞隔開。
