高中英語三大從句

千里之行，始于足下讓知識帶有溫度。第第2頁/共2頁精品文檔推薦高中英語三大從句高中英語主要要把握三大從句。

分離是：

1、定語從句（形容詞從句）

2、名詞詞從句（包括主語從句，賓語從句，表語從句，同位語從句）

3、狀語從句（副詞性從句，包括時光，地點，結果，目的，緣由等）

一、定語從句：

定語從句（AttributiveClauses）在句中做定語，修飾一個名詞或代詞，被修飾的名詞,詞組或代詞即先行詞。定語從句通常浮現在先行詞之后，由關系詞（關系代詞或關系副詞）引出。

1、關系代詞引導的定語從句

關系代詞所代替的先行詞是人或物的名詞或代詞，并在從句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主詞保持全都。

（1）,who,whom,that

這些詞代替指人，“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。

（2），Which用來指人或物

(用作主語、賓語，作賓語時可以省略）

（3），whose

“whose”表示誰（可以為人也可以為物）的（東西）

2、關系代詞引導的定語從句

（1），關系副詞why主要用于修飾表示緣由的名詞（主要是thereason），同時它在定語從句中用作緣由狀語。

（2），關系副詞when主要用于修飾表示時光的名詞，同時它在定語從句中用作時光狀語。

（3），關系副詞where主要用于修飾表示地點的名詞，同時它在定語從句中用作地點狀語。

3、非限制性定語從句

它起補充說明作用，缺少也不會影響全句的理解。在非限制性定語從句的前面往往有逗號隔開。

二、名詞性從句

在句子中起名詞作用的句子叫名詞性從句(NounClauses）。名詞性從句的功能相當于名詞詞組,它在復合句中能擔任主語、賓語、表語、同位語、介詞賓語等，因此按照它在句中不同的語法功能，名詞性從句又可分離稱為主語從句、賓語從句、表語從句和同位語從句。

引導名詞性從句的銜接詞可分為三類：

1、連詞（5個）：that（賓語從句或表語從句中that有時可以省略）

whether,if（均表示“是否”表明從句內容的不確定性）

asif,asthough（均表示“好似”，“似乎”）

以上在從句中均不充當任何成分

2、銜接代詞（9個）：what,whatever,who,whoever,whom,whomever,whose,which,whichever

3、銜接副詞（7個）：when,where,how,why,whenever,wherever,however

三、狀語從句

狀語從句（AdverbialClause）狀語從句指句子用作狀語時，起副詞作用的句子。它可以修飾謂語、非謂語動詞、定語、狀語或囫圇句子。按照其作用可分為時光、地點、緣由、條件、目的、結果、讓步、方式和比較等從句。狀語從句普通由連詞(從屬連詞)引導，也可以由詞組引起。從句位于句首或句中時通常用逗號與主句隔開，位于句尾時可以不用逗號隔開。

狀語從句細分的話，共包括九種：

1.時光狀語從句

2.地點狀語從句

3.緣由狀語從句

4.條件狀語從句

5.目的狀語從句

6.讓步狀語從句

7.比較狀語從句

8.方式狀語從句

高中英語定語從句匯總講解

發(fā)表日期：2022年1月9日：ZolaStone【編輯錄入：admin】

◆英語諺語觀賞

1.Hewhoknowsnothingbutpretendstoknoweverythingisindeedagood-for–nothing.

不懂裝懂，一事無成.

2.It’sthefirststepthatcosts.千里之行，始于足下

3.Hethatmakeshimselfasheepshallbeeatenbythewolf.甘當小綿羊，遲早要喂狼.

Ⅰ.概念：

(1)定語從句：在主從復合句中用作定語的從句叫定語從句。定語從句普通緊接在先行詞(antecedent)后面。

(2)先行詞：被定語從句修飾的成份。先行詞可以為一個詞，短語，或囫圇主句。

(3)引導定語從句的詞叫關系詞，分為關系代詞和關系副詞。

關系詞的作用：

1)引導定語從句，銜接主句和從句，相當于一個連詞；

2)必在從句中作某個句子成份（可以做主語，賓語，表語，定語，狀語）

常用的關系代詞:that、which、who、whom、whose、as、but(文語,置于否定詞之后=that/who…not…,"沒有……不……",在從句中作主語，賓語)

常用的關系副詞（在從句中只作狀語）:when、why、where

ThestudentwhoansweredthequestionwasJohn.

Iknowthereasonwhyhewassoangry.

Theboy(whom)youaretalkingtoismybrother.

I'dlikearoomwhosewindowlooksoutoverthesea.

定語從句三步：

第一找出先行詞；

其次看先行詞在定語從句中的語法功能（做主語、賓語或狀語）；

第三挑選合適的關系詞。

Ⅱ.幾個關系代詞的基本用法：

●that:可指人或物；在定語從句中作主語，賓語，表語。(指人時，相當于who或whom；指物時，相當于which)(普通不用于非限制性定語從句;不行置于介詞后作賓語)如：

1.Aletterthat/whichiswritteninpencilisdifficulttoread.(主語)

2.Doyouknowthegentlemanthat/whospokejustnow?

3.Youcantakeanything(that)youlike.（賓語）

4.Whatisthequestion(that/which)theyaretalkingabout?

5.Hereistheman(who/whom/that)youwanttosee.

6.She'snolongerthegirl(that)sheusedtobebefore.（表語）

7.Ourhometownisnolongertheone(that)itusedtobe.

=Ourhometownisnotthesameasitusedtobe.

=Ourhometownisdifferentfromwhatitusedtobe。

=Ourhometownisnotwhatitusedtobe.

●which:指物；在定語從句中作主語，賓語，表語，定語。如：

1.Thebookwhich/thatwasonthedeskwasboughtbymyfather.（主語）

2.Thebook(which/that)Iboughtyesterdayisveryinteresting.（賓語）

3.Thefactoryinwhichhisfatherworksisfarfromhere.

4.Hewasproud,whichhisbrotherneverwas.（表語）

5.Tomspentfouryearsincollege,duringwhichtimehelearnedFrench.（定語）

6.Hemaybelate,inwhichcaseweoughttowaitforhim.

●who,whom,whose:

who:主格,在從句中作主語，在口語或非正式用法中作賓語;只可指人

whom:賓格，在從句中作賓語;只可指人

whose:屬格，在從句中作定語，可指人也可指物。

Ilikethestudentswho/thatworkhard.（主語）

Allwhoheardthestorywereamazed.(代詞如he,they,any,those,all,one等后多用who.)Chaplin,forwhomlifehadoncebeenveryhard,wasasuccessasanactor.（賓語）

He'samanfromwhomweshouldlearn.

=He'saman(whom/who/that)weshouldlearnfrom.

比較：Heisthestudentwhomyouthinktobeworthyofyourpraise.

Heisthestudentwhoyouthinkisworthpraising.

Achildwhoseparentsaredeadiscalledanorphan.（指人）

I'dlikearoomwhosewindowfacessouth.（指物）

=I'dlikearoomofwhichthewindowfacessouth.

=I'dlikearoomthewindowofwhichfacessouth.

ThereisateapotshapedlikeaChineseduck,outofwhosemouthteaissupposedtocome

關系代詞作介詞賓語:

關系代詞在定語從句中用作介詞賓語時,介詞可放于從句之首,也可放于從句之末.但以放于句首較為正式.（介詞前置，必需注重不影響動詞詞組的含義。關系代詞who和that用作介詞賓語時,介詞必需放在句末.）

Thisisthebookforwhichyouasked.

=Thisisthebook(that/which)youaskedfor.

DoyouknowthepersonwithwhomIshookhands？=Doyouknowtheperson(whom/who/that)Ishookhandswith?

Thebeginningofagriculturewasabigstepinhumanprogresswithwhichnothingcouldcompareuntilourinformationage.

Inthedarkstreet,therewasn'tasinglepersontowhomshecouldturnforhelp.

Isthisthefactorytowhichyoupaidavisitlastweek?

Isthisfactorytheonetowhichyoupaidavisitlastweek?

Thisisthegirlwhomtheyarelookingafter.(介詞after與look構成固定詞組，不行前置。lookat,lookfor,lookafter,takecareof等)

●as的用法:(as引導定語從句,在定語從句中作主語、賓語、表語)

①如為限制性的，多用于thesame…as;thesameas；such…as…;asmany/muchas；so…as等結構中。如：

※Ihavethesamebookasyou(have).我有一本和你的一樣的書。

Herattitudetohimwasquitethesameasithadalwaysbeen.(關系代詞as和指示代詞same連用,在從句中用作表語,先行詞是same.)

※.Whydidn'tyoumentionthatinfaceofthepolicejustnow?

Ithoughtitwassuchaminordetailaswashardlyworthmentioning.

Wewillonlydiscusssuchproblemsashavesomethingtodowithourowninterests.

Don'tdosuchthingsasyouarenotsureabout.

Thereisnosuchplaceasyoudreamofinallthisworld.

比較：Iliveinthesamehousethatheusedtolivein.

I'mwearingthesameshirtasyouworeyesterday.

比較：Hereissobigastoneasnoonecanlift.（定語從句）

Hereissobigastonethatnoonecanliftit.（結果狀語從句）

②如為非限制性的，多單獨引導一個定語從句，這種定語從句可置于句首，句中或句尾，譯為"正如，這一點"。（動詞常為know,see,expect,pointout,etc.）

※Asweallknow,smokingisharmfultoone'shealth.(as作賓語)

=Asisknowntoall,smokingisharmfultoone'shealth.（as作主語）

=It'sknowntoallthatsmokingisharmfultoone'shealth.

=Smokingisharmfultoone'shealth,asweallknow.（as作賓語）

=Smoking,asweallknow,isharmfultoone'health.

※Hewasaforeigner,asIknewfromhisaccent.(賓語,先行詞是前面囫圇句子)

Ⅲ.關系副詞引導的定語從句:

●When指時光，在定語從句中作時光狀語。其先行詞是表時光的名詞（如：time,day,week,tear,month,etc.）

HecamelastnightwhenIwasout.

Wewillputoffthepicnicuntilnextweek,whentheweatherwouldbebetter.

注重：先行詞為"時光名詞"，可用when引導定語從句，when在定語從句中作狀語；還可以用which或that引導，which或that在從句中作主語或賓語。

比較:Istillrememberthedaywhen/onwhichmybrotherjoinedthearmy.（作狀語）

Nextmonth,whenyouwillbeinyourhometown,isjustaroundthecorner.

Istillrememberthedayswhich/thatwespenttogether.（作賓語）

Nextwinterwhich/thatyou'llspendinHarbin,I'msure,willbeexciting.

IshallneverforgetthedaywhenShenZhouⅤwaslaunched,whichhasagreateffectonmylife.

Thereareoccasionswhenjokingisnotpermissible.

●Where指地點，在定語從句中作地點狀語。其先行詞是表示地點的名詞，如：place,school,factory,room,etc.

ThisistheplacewhereIwasborn.

Iliveintheroomwhere/inwhichheusedtolive.

注重：先行詞是"地點名詞"，定語從句可用where引導，還可用which或that引導，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指緣由，在定語從句中作緣由狀語。先行詞為reason時，可用forwhich指代；當關系詞在從句中作主語或賓語時，則用which或that引導。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)

當先行詞為way時，定語從句常用that,inwhich,或how引導，that常可以省略。

way后的定語從句的引導詞不用時較多。但假如關系詞在句中作主語或賓語

時，則用which或that引導。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)分：

1.形式上，非限制性定語從句往往用逗號隔開。

2.語法上，非限制性定語從句普通不用that.

3.語義上，限制性定語從句與先行詞關系緊密，起限定作用，假如去掉了這個定語從句，囫圇句子就不完整或者會轉變意思；而非限制性定語從句與先行詞關系不是很緊密，對先行詞起補充說明或描述的作用。

ThisisthebookIlikebest.這就是我最喜愛?的那本書。

Beijing,whichhasbeenChina'scapitalformorethan800years,isrichinculturalandhistoricrelics.北京是中國八百年之久的古都，它有著豐盛的文化和歷史遺產。

4.翻譯時，限制性定語從句可譯為一句（較短的普通譯為"的"字結構）；而非限制性定語從句可譯為兩句。（見上句翻譯）

比較:Hehasasister,whoisamusician.

Hehasasisterwhoisamusician.

引導非限制性定語從句的關系代詞，指人時用who,whom,whose,指物時用which,whose;關系副詞when，where,why,etc.

1.Hestudiedhardatschoolwhenhewasyoung,whichleadstohissuccessinhislaterlife.

2.Tom'sfather,whoarrivedjustnow,isafamousscientist.

3.Theysetupaseparatestateoftheirown,wheretheywouldbefreetokeepNegroesasslaves.

4.Hewasproud,whichhisbrotherneverwas.

Ⅴ.幾個易混淆的關系代詞的比較:

●that&which:

在定語從句中，which和that在指代事物時，普通可以互換使用，但并非在任何狀況下都是這樣，這里介紹宜用that,而不宜用which的狀況.

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。

1.Theonlythingthatwecoulddowastowait.

2.That'stheverywordthatiswronglyused.

Thelastplace(that)wevisitedwasthechemicalworks.

Youcantakeany(=whichever)seatthatisfree.

IhopethelittlethatIcanwillbeofsomehelptothem.

比較*Thisisoneofthebestnovelsthatwerepublishedlastyear.

*Thisistheonlyoneofthebestnovelsthatwaspublishedlastyear.

③先行詞是序數詞時或被序數詞修飾時。

1.WhenwetalkaboutWuxi,thefirstthatcomesintomindisTaiLake.

2.Thisisthethirdfilmthathasbeenshowninourschoolthisterm.

④先行詞是最高級或被最高級修飾時。

1.Thisisthebestthatcanbedonenow.

2.Themostimportantthingthatshouldbedonerightnowishowtostophimfromgoingon.

⑤先行詞既有人又有物，用which和who都不適合，這時宜用that.如：

1.Thewriterandhisnovelthatyouhavejusttalkedaboutisreallywellknown.

2.Theriderandhisbikethathadrunoveranoldwomanwereheldupbythepolice.

⑥被修飾詞為數詞時.

1.YesterdayIcaughttwofishandputtheminabasinofwater.Nowyoucanseethetwothatarestillalive.

⑦假如有兩個從句，其中一個關系代詞已用which,另一個關系代詞宜用that，以避開語言的單調或重復。

Edisonbuiltupafactorywhichproducedthingsthathadneverbeenseenbefore.

⑧疑問詞是who或which，關系代詞宜用that，以避開重復。

1.Whichisthebookthatyoulikebest?

2.Whoisthemanthatisstandingatthegate?

⑨主句是Therebe結構，修飾其主句的定語從句宜用that作關系代詞.如：

1.Thereisstillaseatinthecornerthatisstillfree.

⑩被修飾成分為表語時，或者關系代詞本身是定語從句的表語時,該關系代詞宜用that.

1.That'sagoodbookthatwillhelpyoualot.

2.Myhomevillageisnolongertheplace(that)itusedtobe.

定語從句中宜用which而不宜用that的狀況:

①當關系代詞的前面有介詞時.

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在一個句子中有兩個定語從句，其中一個定語從句的關系代詞用了that,另一個宜用which.

1.Letmeshowyouthenovel，thatIborrowedfromthelibrarywhichwasnewlyopentous.

2.AtthestationIboughtsomemagazinesthatmighthelpmetopassthetimeonthetrainandwhichIcouldpassontootherswhenIfinishedthem.

④當關系代詞后面帶有插入語時.

1.Here'stheEnglishgrammarwhich,asIhavetoldyou,willhelpimproveyourEnglish.

⑤先行詞本身是that,宜用which.

What'sthatwhichsheislookingat?

⑥先行詞是those+復數名詞.

Ashopshouldkeepastockofthosegoodswhichsellbest.

(B)who&that:

who和that指代人時，有些狀況宜用who,而不宜用that

①先行詞為anyone,anybody,those,all,one,ones,they,he,people時.如：

1.ThepersonIwanttolearnfromistheonewhostudieshardandworkswell.

2.Anyonewho(=Whoever)failedtocometothemeetingyesterdaymustgivehisreason.

3.Thosewhoarenotfitfortheirworkshouldleaveofficeatonce

4.Idon'tliketheones(=those)whotalkbig.

5.Personswhoarequarrelsomearedespised.

②在Therebe結構中，修飾主語的定語從句宜用關系代詞who指代人.如：

1.Thereisagentlemanwhowantstoseeyou.

2.Thereareseveralstudentsinourclasswhoarestillnotsureabouttheuseofattributiveclauses.

③當先行詞有較長的后置定語時.如：

1.ImetaforeignerintheparkyesterdayafternoonwhocouldspeakChineseverywell.

④一個句子中帶有兩個定語從句，其中一個定語從句的關系代詞是that,另一個則宜用who,以免重復.如：

1.Thestudentthatwaspraisedatyesterday'smeetingisthemonitorwhoisverymodestandworksveryhard.

●as&which:

as&which引導非限制性定語從句的區(qū)分：

①位置的不同：

which引導的定語從句只置于所限制的句子后；as位置較靈便，也就是說as可置于所限

制的句子前面；插在句子中或放在句子后。如：

1.Hewaslateagain,whichmadehisteacherveryangry.

2.Jack,asyouknow,isanhonestman.或Jackisanhonestman,asyouknow.

或Asyouknow,Jackisanhonestman.

②先行詞的不同：

as引導非限制性定語從句時，其先行詞多為一個句子；

which引導非限制性定語從句時，其先行詞可以是一個詞，一個短語或一個句子。

※Hewasproud,whichhisbrotherneverwas.（先行詞是一個詞）

Shewasverypatienttowardsthechildren,whichherhusbandseldomwas.

Hewasproud,whichIdislikeverymuch.（先行詞是一個句子）

※Heisanhonestman,asisknowntoall.

Hewasaforeigner,asIknowfromhisaccent.

③as普通譯為"正如""就像"，"這一點"

asweallknow；asyouknow;asisknowntoall;asyousee;aswecansee;ashasbeenexpected;aswehaveimagined.
