要學定語從句，得知道什麼是定語。定語是用來限定、修飾名詞或代詞的。那麼在會考中常考福定語從句知識是哪些？
會考英語常見考點：定語從句
一、關係代詞引導的定語從句
1、由who, whom, that，Whose引導的從句
這些詞代替的先行詞是人的名詞或代詞，who作主語指人，whom作賓語指人，that既可作主語又可作賓語（作賓語可以省略），可以指人也可以指物。Whose 用來指人或物，只用作定語。
(1) Is he the man who/that wants to see you? 他是那個想見你的男人嗎？（who/that在從句中作主語）
(2) He is the man whom/ that I saw yesterday. 他就是我昨天見的那個人。（whom/that在從句中作賓語）
(3) The man whom you spoke to just now is our English teacher 你剛剛說話的那個男人是我們的英語老師
(4) he man whose son is a doctor is our professor. 那個兒子是醫生的男人是我們的教授。
2、由which, that引導的從句
它們所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等，作賓語時可以省略，例如：
(1) Prosperity which / that had never been seen before appears in the countryside. 農村出現了前所未有的繁榮。（which / that在從句中作主語）
(2) The package (which / that) you are carrying is about to come unwrapped. 你拿那個包裹快要散開了。(which / that在從句中作賓語）
注意： 代表物時多用which，但在下列情況中用that而不用which：
a)先行詞是anything, everything, nothing , none等不定代詞時；
b)先行詞由every, any, all, some, no, little, few, much等修飾時，這時的that常被省略；
c)先行詞前有序數詞或被形容詞最高級修飾時；
d)先行詞中既有人又有物時；
e)整個句中前面已有which，who,that時；
f)當先行詞爲 物並作表語時；
g)先行詞爲one時；
h)先行詞同時又被the only,the very,the same修飾時；
二、關係副詞引導的定 語從句
1、when指時間在定語從句中做時間狀語也可做連接詞用 I still remember the day when I first came to the school.
2、where指地點在定語從句中做地點狀語 Shanghai is the city where I was born.
3、why指原因在定語從句中做原因狀語 ，用在reason 後面。 Please tell me the reason why you missed the plane.
常見考法
對於定語從句的'考查，多以單選的形式 考查學生靈活運用的能力。一般情況下，常從關係詞的意義和功能的角度考查，重點是that,which,who引導的定語從句。
典型例題：You're the only person ______I've ever met ______could do it .
A. who B. whom C. whom D. who
解析：先行詞person後有兩個定語從句,第一個從句省略了關係代詞whom.因爲, wh om作從句中met的賓語,可以省略.第二 個從句who could do 在從句中作主語,不可省略.
答案：D
誤區提醒
當表示時間或地點的名詞作先行詞時，要判斷出它們在從句中作狀語還是主語或賓語。作狀語時用關係副詞，反之用關係代詞。
典型例題：I c an never forget the day _______ we worked together and the day ______ we spent together .
A . when; which B. which; when C. what; that D. o n which; when
解析 ：. 兩個先行詞the day都是表示時間的名詞,但第一個空白處要填的關係詞在從句中作狀語,因此要用關係副詞when. 第二個空白處要填的關係詞在從句中作動詞spent的賓語,因此要用關係代詞which或that來引導定語從句.
