用作定語的從句叫作定語從句（AttributiveClause）。定語從句通常皆置于它所修飾的名詞（或代詞）之后，這種名詞（或代詞）叫作先行詞（antecedent）。引導(dǎo)定語從句的關(guān)聯(lián)詞為關(guān)系代詞和關(guān)系副詞。關(guān)系代詞在定語從句中可用作主語、賓語、定語等；關(guān)系副詞在定語從句中只用作狀語。定語從句可分為限制性定語從句（RestrictiveAttributiveClause）與描述性定語從句（Non-RestrictiveAttributiveClause，又稱作非限制性定語從句）。限制性定語從句與先行詞關(guān)系密切，對它有限制作用。因此不可缺少，否則會影響全句的意義。1.定語從句與先行詞的位置

定語從句一般緊跟其先行詞之后。有時亦可與先行詞分離。Theroomwhichservedforstudiowasdusty.（關(guān)系代詞which引導(dǎo)的定語從句緊跟其先行詞room之后）這個用作工作室的房間布滿灰塵。AnewmasterwillcometomorrowwhowillteachyouGerman.（關(guān)系代詞who引導(dǎo)的定語從句與其先行詞master分離）明天要來一位新教師教你們德語了。19限制性定語從句2.用作關(guān)聯(lián)詞的關(guān)系代詞

常見的關(guān)系代詞有兩種——代替人的關(guān)系代詞和代替物的關(guān)系代詞。（1）代替人1）關(guān)系代詞who或that充當(dāng)從句的主語：Hewasthebestkingwho/thateversatonthethrone.(who/that=theking)他是登上王位的最好的國王。2）關(guān)系代詞whom或who或that充當(dāng)從句的賓語：whom是非常正式的形式，幾乎不用于口語中。因此，在口語中，我們用who或that（that比who更常用），但更為常見的是省略關(guān)系代詞。Theman(that/whom)youmetyesterdayisanactor.(that/whom是met的賓語，代表theman)代替對象主格賓格所有格人who/

that------19限制性定語從句你昨天遇見的那個人是個演員。Thegirls(who/whom/that)heemploysarealwayscomplainingabouttheirlonghours.(who/whom/that=thegirls)他雇傭的那些女孩子老是抱怨她們的工作時間太長。3）whose——唯一的關(guān)系代詞所有格形式：Thepilotwhoseplanelandedinafieldwasnothurt.(whose=his)飛機(jī)降落在地里的那個飛行員沒有受傷。Peoplewhoserentshavebeenraisedcanappeal.(whose=their)房租被提高的人們可以起訴。（2）代替物1）關(guān)系代詞which或that充當(dāng)從句的主語，which較為正式：Thepathwhich/thatleadstothegardenisratherslippery.(which/that=thepath)通往花園的小路相當(dāng)滑。2）關(guān)系代詞which或that充當(dāng)從句的賓語；關(guān)系代詞也可以省略：19限制性定語從句

Thankyouforthehelp(which/that)youhavegiventome.(which/that=thehelp)

謝謝你給我的幫助。

注意：關(guān)系代詞在從句中作賓語時往往可以省略。另外，定語從句的時態(tài)一般不受主語的限制，但謂語動詞的數(shù)的變化取決于先行詞：Alltheapplesthatfalldownareeatenbythepigs.所有掉下來的蘋果都被豬吃掉了。（定語從句的先行詞是apples，因此必須用復(fù)數(shù)謂語動詞fall）3.用作關(guān)聯(lián)詞的關(guān)系副詞用作關(guān)聯(lián)詞的關(guān)系副詞有when，where，why等。when/where/

why等相當(dāng)于“介詞+which”。

IwentoffinsearchofagaragewhereIcouldbuysomepetrol.(where=inwhich)我出發(fā)去尋找汽車修理廠，以便買一些汽油。At65,anagewhenmanymenretire,hebeganthegreatestvoyageofhislife.(when=atwhich)65歲是許多男子退休的年齡，但他卻開始了人生最偉大的航程。19限制性定語從句1.OralpracticeWorkinpairsandtalkaboutthefastfoodrestaurantyoulikebest.2.Fillinblankswiththeproperrelativepronouns.
