1關(guān)系代詞和關(guān)系副詞在定語從句中都要 充當(dāng)句子成分。

2當(dāng)關(guān)系代詞充當(dāng)動詞的賓語時可省略，當(dāng)關(guān)系代詞充當(dāng)介詞的賓語且介詞不在關(guān)系代詞之前的，關(guān)系代詞也可省略。

3定語從句中的謂語動詞要和先行詞保持一致。

4定語從句分為限制性和非限制性兩種。

5非限制性定語從句中的關(guān)系詞不可以省略并且一定不能用that引導(dǎo)。關(guān)系詞先行詞所指關(guān)系詞在句中作用關(guān)系代詞that人/物主、賓、表which物主、賓、who人主、賓whom人賓whose人/物定as人/物/事情主、賓、表關(guān)系副詞when時間時間狀語where地點(diǎn)地點(diǎn)狀語why原因原因狀語

關(guān)系詞（引導(dǎo)詞）的作用：

1、連接作用把主句和從句連接起來（可以從句子之間有連詞來理解）

2、替代作用在從句中代替在它前面 的先行詞

3、成分作用在從句中充當(dāng)一個成分（區(qū)分定語從句和同位語從句）Titanicistheship___________sankafterhittinganiceberg.which/that__________v.下沉ZhangGuorongisapopstar______diedinthefallinMarch,2003.

注意：which引導(dǎo)的非限制性定語從句。

Ihavelostmypen,whichIlikevery much.Shewasawardedagoldmedal,whichthe wholefamilyconsideredagreathonor.Sheisalwayslateforclass,whichmakes theteacherangry.非限定性定語從句一定不能用that引導(dǎo)！三、由that引導(dǎo)的定語從句。that在從句中可以指人或物，在從句中做主語或謂語動詞的賓語。Aplaneisamachinethatcanfly.TheletterthatIreceivedwasfrommyfather.但不能放在____詞后面作賓語。Thisistheschoolinthatyouwillstudy.(×)Thisistheschoolinwhichyouwillstudy.(√)Thisistheschool(which/that)youwillstudyin.(√)介★注意在下面幾種情況下必須用that引導(dǎo)定語從句。⑴先行詞是________________________________________________

Allthatwehavetodoistopractiseeveryday.

Somethingthatweheardwasofgreattruth.不定代詞all,few,littkemuch,something,nothing,anything等。當(dāng)先行詞是all,everybody,nobody,anybody等不定代詞時，如關(guān)系代詞在從句中當(dāng)主語，則優(yōu)先選用who連接主從句。Everybodywhowerewillingtoseethefilmsignedtheirnameshere.⑵先行詞被______________________________所修飾。

ThefirstthingthatIlearnedwillneverbe forgotten.ThisisthemostinterestingfilmthatIhave everseen.⑶先行詞被_____________________________等修飾。

Ihavereadallthebooksthatyougaveme.序數(shù)詞、thelast或形容詞的最高級all,any,every,each,few,little,no,some⑷先行詞被theonly,thevery修飾。

ThisistheverypenthatIamlookingfor.HeistheonlypersonthatIwanttotalkto.⑸先行詞______________。

Theytalkedofthingsandpersons

thattheyremembered.既有人又有物時⑹當(dāng)句中已有who或which時，為避免重復(fù)。WhoisthemanthatistalkingtoJohn?四、as引導(dǎo)的定語從句:⑴as用作關(guān)系代詞和關(guān)系副詞引導(dǎo)限制性定語從句，并在從句中做主語、表語和狀語，構(gòu)成thesame…as,such…as等結(jié)構(gòu)。

Iwanttohavesuchadictionaryashehas.Ishalldoitinthesamewayasyoudid.Ilikethesamebookasyoudo.⑵as引導(dǎo)非限制性定語。在從句中做主語、表語或賓語，這個定語從句說明整個句子，可以放在主句之前、之中和之后。Asisknowntoall,hestudiesveryhard.Asweallknow,Chinaisadevelopingcountry.注意：which和as的區(qū)別是：①which不能放在句首，而as則可以；②在句中時，as有“正如”、“就像”之意，而which沒有。③從句的結(jié)構(gòu)為“主語+謂語+賓語”時，as只可以作賓語，不可以做主語，而which都可以。1、由where引導(dǎo)的定語從句。定語從句在修飾一個表示____的名詞時,常用where引導(dǎo)。Abookofficeisaplacewhereticketsaresold.Where在從句中做_________，相當(dāng)于一個介詞短語。Abookofficeisaplaceinwhichticketsaresold.因此定語從句中關(guān)系副詞where=_____

+_____.關(guān)系副詞引導(dǎo)的定語從句：地點(diǎn)地點(diǎn)狀語介詞whichThisisthehousewherehelives.=Thisisthehouse___________helives.=Thisisthehouse___________helivesin.inwhich(which/that)2、定語從句在修飾一個表示_____的名詞時，常用when引導(dǎo)。Istillremembertheyearwhenwestudiedtogether.when在從句中_______________，其作用相當(dāng)于一個“介詞+關(guān)系代詞”Istillremembertheyear____________westudiedintogether.Istillremembertheyearinwhichwestudiedtogether.時間時間狀語which/that因此定語從句中關(guān)系副詞when=______+______介詞which3、由why引導(dǎo)的定語從句。①關(guān)系副詞why的先行詞只有reason,在從句中表示__________。DoyouknowthereasonwhyIleftearly?Why在從句中作原因狀語，其作用相當(dāng)于forwhich.Doyouknowthereason_____________Ileftearly?②但如果關(guān)系詞在從句中不是作狀語，而是作賓語時仍用that/which.Thereason___________hegaveuswasunacceptable.forwhichthat/which原因狀語關(guān)系代詞和關(guān)系副詞的選用。在定語從句中到底選用關(guān)系代詞還是關(guān)系副詞要看它們在從句中所充當(dāng)?shù)木渥映煞謥頉Q定，有時同一個先行詞往往關(guān)系詞卻不同。1.Thisisthefactory_____________producesTVsets.Thisisthefactory_________myfatheronceworked.2.I’llneverforgettheday____________wespenttogetherinthecountryside.I’llneverforgettheday________hishousewasbrokeninto.which/thatwherewhich/thatwhen3.Isthisthereason______________hetoldyou?Isthisthereason________hewaslateforclass? which/thatwhy限制性定語從句與非限制性定語從句:限制性定語從句非限制性定語從句和先行詞關(guān)系密切（刪去影響整個意思表達(dá)）和先行詞關(guān)系不密切（一種補(bǔ)充說明，刪去不影響全句意思的表達(dá)）不用逗號隔開一般用逗號隔開可用關(guān)系代詞that不可用關(guān)系代詞that關(guān)系代詞可省略（但在從句中作賓語）關(guān)系代詞不可以省略只可修飾先行詞，不可以修飾主句或主句的一部分除修飾先行詞還可以修飾整個主句或主句的一部分暗示被修飾的先行詞不是唯一的表示被修飾的先行詞是唯一的翻譯時先翻譯從句在翻譯主句翻譯時先譯主句再譯從句ExerciseFillintheblacks1.Ihaveafriend__________likeslisteningtoclassicalmusic.2.YesterdayEmilywaswearingthenewdress__________Igaveher.3.Theman______legbrokeinamatchusedtobeafootballplayer.4.Myparentsliveinahouse___________ismorethan100yearsold.5.Theboywith_______Johnspokeismybrother.6.Kevinisreadingabook__________istoodifficultforhim.who/thatwhich/thatwhosewhich/thatwhomwhich/that7.Isthereanything_______youwanttobuyinthetown.8.All______wecandoistostudyhard.9.RecentlyIboughtanancientChinesevase,thepriceof______wasveryreasonable.10.Theonlylanguage_____iseasytolearnisthemothertongue.11.Doyoustillremembertheday_____IfirstcametoBeijing?12.I’mgoingtovisittheschool______mymothertaughtphysicstenyearsago.thatthatwhichthatwhenwhere13.Theretiringteachermadeaspeech_____whichshethankedtheclassforthegift.14.Whichofthetwocows______youkeepproducesmoremilk?15.Motherboughtmeadictionaryonmybirthday,______mademeveryhappy.16.______isknown,heissuchabelovedteacher____westudentsallexpected.17.Chinahashundredsofislands,______whichthelargestisTaiwan.18.Heoftenhelpsthestudents____hatwhichAsasofwho19.Hisglasses,_______whichhewaslikeablindman,felltothegroundandbroke.20.Willthebook______coverisbluebedonatedtotheremoteschool?21.Jimlikestoliveinthehouse___________isontopofagreenhill.22.Jimlikestoliveinthehouse_______hegrewup.23.Jimlikestoliveinthehouse______windowfacesthegreenhill.24.Thereason_____Tomstolethe
