英语试讲1，Isthereanything()Icandoforyou?3，Thebiggestbird()Icaughtyesterdayisthisbird.2，Theproject,()lastedfouryears,costonebilliondollars.4,Hetalkedabouttheteachersandschools()hevisited.thatthatwhichthat①先行词为不定代词:all,much,something,everything,none,theone等,e.g.Allthatisneededisasupplyofoil.②先行词是no,little,theonly,thevery,thesame,thelast等或被这些词修饰时,e.g.Shehaslittleinformationthatisusefulforourresearch.③先行词是序数词或被序数词修饰时。e.g.1，WhenwetalkaboutLuzhou,thefirstthatcomesintomindiswine.2，Thisisthethirdfilmthathasbeenshowninourschoolthisterm.④先行词是形容词最高级或被最高级修饰时。e.g.1,Thisisthebestthatcanbedonenow.2,ThisisthebestdictionarythatI’veeverused.在定语从句中，that和which在指代事物时，一般可以互换使用，但并非在任何情况下都是这样。这里先介绍只能用that作为定语从句的关系代词的情况：⑥先行词既有人又有物，用which和who都不适合，这时宜用that。e.g.Thewriterandhisnovelthatyouhavejusttalkedaboutisreallywell-known.⑤先行词为数词时，e.g.YesterdayIcaughttwofishandputtheminabasinofwater,Nowyoucanseethetwothatarestillalive.⑦1,如果有两个从句，其中一个关系代词已用which,另一个关系代词宜用that,以避免语言的单调或重复。e.g.Edisonbuiltupafactorywhichproducedthingsthathadneverbeenseenbefore.2,当主句是以which或who开始的特殊疑问句时，为避免重复用that,如Whichisthecarthatkilledtheman?⑧在therebe句型中，只用that不用which.e.g.Thereisstillaseatinthecornerthatisstillfree.二、定语从句中宜用which而不宜用that的情况：①当关系代词的前面有介词时.e.g.1,Azooisaparkinwhichmanykindsofanimalsarekeptforexhibition.2,IsthistheroominwhichRoselives?②在非限制性定语从句中.e.g.MoreandmorepeoplearebeginningtolearnEnglish,whichisbecomingverypopularinourcountry.③先行词本身是that.e.g.What’sthatwhichsheislookingat?1，Thecurrent,()isveryrapid,makestheriverdangerous.3，Thedocumentsfor()theyweresearchinghavebeenrecovered.2,Theonlything()couldbedoneistofindourwayhome.4，ThefirstEnglishbook()Ireadwas“Thelittleprince”.5，Whoistheperson()isstandingatthegate?Practicewhichwhichthat6,Thesleepingman’ssubconsciousmindretainedeverything()wassaidaroundhim.7,ThusthenexttaskbeganofclearingArabforcesfromtheareaandthenrebuildingtheroad,()wouldbepavedandfivemeterswide.8,Hehadacoupleofrevolverswith()hecoulddefendhimself.9,Thereisnopossibility()hewillbeheretomorrow.thatwhichwhichthat谢谢观赏。
