eusedtolive.注意：先行詞是"地點(diǎn)名詞"，定語從句可用where引導(dǎo)，還可用which或that引導(dǎo)，which/that在從句中作主語或賓語。比較:※Thisisthefactorywhere/inwhichheworkedlastyear.（作狀語）Thetreatmentwillcontinueuntilthepatientreachesthepointwherehecanwalkcorrectlyandsafely.Ithinkyouhavegottothepointwhereachangeisneeded,oryouwouldfail.Governmentreports,legalpapersandmostbusinesslettersarethemainsituationswhereEnglishisused.He'sgothimselfintoadangeroussituationwherehe'slikelytolosecontroloftheplane.Thesmallmountainvillagewherewespentourholidaylastmonthliesinwhat/theplacewhichisnowpartofHubei.Thisistheparkwhich/thattheyvisitedlastyear.（作賓語）Nothavingbeentherebefore,hesimplyhadnoideaabouttheplace,whicheveryonesaysisworthvisiting.●Why指原因，在定語從句中作原因狀語。先行詞為reason時(shí)，可用forwhich指代；當(dāng)關(guān)系詞在從句中作主語或賓語時(shí)，則用which或that引導(dǎo)。如：Thereasonwhy/forwhich/(that)hedidn'tattendthemeetingwasthathewasill.Idon'tbelievethereason(that/which)hegaveme.（作賓語）Haveyouaskedhimthereasonthatmayexplainhissuccess?（作主語）Ex.)Hewaslate.That'sbecausehegotuplate..Hegotuplate.That'swhyhewaslate.(表語從句)(thereason)why/forwhichhewaslate.(定語從句)當(dāng)先行詞為way時(shí)，定語從句常用that,inwhich,或how引導(dǎo)，that?？梢允÷浴ay后的定語從句的引導(dǎo)詞不用時(shí)較多。但如果關(guān)系詞在句中作主語或賓語時(shí)，則用which或that引導(dǎo)。如:Thisistheway(that)/inwhichIdosuchthings.比較:Pleasedotheexperimentintheway（that/which）Ihaveshownyou.Ⅳ.限制性定語從句與非限制性定語從句的區(qū)別：1.形式上，非限制性定語從句往往用逗號(hào)隔開。2.語法上，非限制性定語從句一般不用that.3.語義上，限制性定語從句與先行詞關(guān)系緊密，起限定作用，如果去掉了這個(gè)定語從句，整個(gè)句子就不完整或者會(huì)改變意思；而非限制性定語從句與先行詞關(guān)系不是很緊密，對先行詞起補(bǔ)充說明或描述的作用。ThisisthebookIlikebest.這就是我最喜歡的那本書。Beijing,whichhasbeenChina'scapitalformorethan800years,isrichinculturalandhistoricrelics.北京是中國八百年之久的古都，它有著豐富的文化和歷史遺產(chǎn)。4.翻譯時(shí)，限制性定語從句可譯為一句（較短的一般譯為"的"字結(jié)構(gòu)）；而非限制性定語從句可譯為兩句。（見上句翻譯）比較:Hehasasister,whoisamusician.Hehasasisterwhoisamusician.引導(dǎo)非限制性定語從句的關(guān)系代詞，指人時(shí)用who,whom,whose,指物時(shí)用which,whose;關(guān)系副詞when，where,why,etc.1.Hestudiedhardatschoolwhenhewasyoung,whichleadstohissuccessinhislaterlife.2.Tom'sfather,whoarrivedjustnow,isafamousscientist.3.Theysetupaseparatestateoftheirown,wheretheywouldbefreetokeepNegroesasslaves.4.Hewasproud,whichhisbrotherneverwas.Ⅴ.幾個(gè)易混淆的關(guān)系代詞的比較:●that&which:在定語從句中，which和that在指代事物時(shí)，一般可以互換使用，但并非在任何情況下都是這樣，這里介紹宜用that,而不宜用which的情況.①先行詞為不定代詞,all,much,something,everything,anything,nothing,none,theone等,1.Weshoulddoallthatisusefultothepeople.2.There'snothingthatcanbesaidaboutit.3.Doyoumeantheonethatwasboughtyesterday?②先行詞被only,any,few,little,no,just,very,oneof等詞修飾時(shí)。1.Theonlythingthatwecoulddowastowait.2.That'stheverywordthatiswronglyused.Thelastplace(that)wevisitedwasthechemicalworks.Youcantakeany(=whichever)seatthatisfree.IhopethelittlethatIcanwillbeofsomehelptothem.比較*Thisisoneofthebestnovelsthatwerepublishedlastyear.*Thisistheonlyoneofthebestnovelsthatwaspublishedlastyear.③先行詞是序數(shù)詞時(shí)或被序數(shù)詞修飾時(shí)。1.WhenwetalkaboutWuxi,thefirstthatcomesintomindisTaiLake.2.Thisisthethirdfilmthathasbeenshowninourschoolthisterm.④先行詞是最高級(jí)或被最高級(jí)修飾時(shí)。1.Thisisthebestthatcanbedonenow.2.Themostimportantthingthatshouldbedonerightnowishowtostophimfromgoingon.⑤先行詞既有人又有物，用which和who都不適合，這時(shí)宜用that.如：1.Thewriterandhisnovelthatyouhavejusttalkedaboutisreallywellknown.2.Theriderandhisbikethathadrunoveranoldwomanwereheldupbythepolice.⑥被修飾詞為數(shù)詞時(shí).1.YesterdayIcaughttwofishandputtheminabasinofwater.Nowyoucanseethetwothatarestillalive.⑦如果有兩個(gè)從句，其中一個(gè)關(guān)系代詞已用which,另一個(gè)關(guān)系代詞宜用that，以避免語言的單調(diào)或重復(fù)。Edisonbuiltupafactorywhichproducedthingsthathadneverbeenseenbefore.⑧疑問詞是who或which，關(guān)系代詞宜用that，以避免重復(fù)。1.Whichisthebookthatyoulikebest?2.Whoisthemanthatisstandingatthegate?⑨主句是Therebe結(jié)構(gòu)，修飾其主句的定語從句宜用that作關(guān)系代詞.如：1.Thereisstillaseatinthecornerthatisstillfree.⑩被修飾成分為表語時(shí)，或者關(guān)系代詞本身是定語從句的表語時(shí),該關(guān)系代詞宜用that.1.That'sagoodbookthatwillhelpyoualot.2.Myhomevillageisnolongertheplace(that)itusedtobe.定語從句中宜用which而不宜用that的情況:①當(dāng)關(guān)系代詞的前面有介詞時(shí).1.Azooisaparkinwhichmanykindsofanimalsarekeptforexhibition.2.IsthistheroominwhichMr.Whitelives?②在非限制性定語從句中.1.Crusoe'sdog,whichwasarenowveryold,becameillanddied.2.MoreandmorepeoplearebeginningtolearnEnglish,whichisbecomingverypopularinourcountry.(which指代主句)③在一個(gè)句子中有兩個(gè)定語從句，其中一個(gè)定語從句的關(guān)系代詞用了that,另一個(gè)宜用which.1.Letmeshowyouthenovel，thatIborrowedfromthelibrarywhichwasnewlyopentous.2.AtthestationIboughtsomemagazinesthatmighthelpmetopassthetimeonthetrainandwhichIcouldpassontootherswhenIfinishedthem.④當(dāng)關(guān)系代詞后面帶有插入語時(shí).1.Here'stheEnglishgrammarwhich,asIhavetoldyou,willhelpimproveyourEnglish.⑤先行詞本身是that,宜用which.What'sthatwhichsheislookingat?⑥先行詞是those+復(fù)數(shù)名詞.Ashopshouldkeepastockofthosegoodswhichsellbest.(B)who&that:who和that指代人時(shí)，有些情況宜用who,而不宜用that①先行詞為anyone,anybody,those,all,one,ones,they,he,people時(shí).如：1.ThepersonIwanttolearnfromistheonewhostudieshardandworkswell.2.Anyonewho(=Whoever)failedtocometothemeetingyesterdaymustgivehisreason.3.Thosewhoarenotfitfortheirworkshouldleaveofficeatonce4.Ido
