名詞性從句復(fù)習(xí)

NounClause名詞性從句TheboyisliMing.Mr.Liang,a24-year-oldboy,teachesusEnglish.主語主語表語同位語賓語1.名詞:表示人或事物的名稱的詞叫名詞。2.名詞在句子當(dāng)中一般可以作什么成分?名詞在句中主要作主語、賓語、表語和同位語。在英語的句子結(jié)構(gòu)中，本來該由名詞充當(dāng)?shù)闹髡Z、賓語、表語和同位語，由一個句子來充當(dāng),這個句子就叫名詞性從句。名詞性從句主語從句(TheSubjectClause)賓語從句(TheObjectClause)表語從句(ThePredicativeClause)同位語從句(TheAppositiveClause)

從句一律保持陳述語序。引導(dǎo)名詞性從句的詞:1.連接詞有：thatwhether和lf2.連接代詞有：whowhomwhosewhichwhat

等3.連接副詞有：whenwherewhyhow等另外whateverwhoeverwhichever等也可以引導(dǎo)主語和賓語兩種從句。名詞性從句中的“that”沒有詞義，也不作任何成分。主語從句(TheSubjectClause)在復(fù)合句中起主語的作用。他星期三來這里是肯定的。_______________________________________iscertain.

HewillcomehereonWednesdayThat注意：從句作主語時，就算是句子意思完整，都要加上從屬連詞that(不做成分也無意義)他星期三是否來這里還不肯定的。____________________________________isnotcertain.WhetherhewillcomehereonWednesday注意：主語從句表示“是否”只用“whether”而不用“if”(不做成分但有意義“是否”

)h

主語從句做主語時,謂語動詞通常用單數(shù).但what引導(dǎo)的從句做主語時,如果表示復(fù)數(shù)意義,謂語動詞用復(fù)數(shù).1.Whathesaid_____muchforustothinkabout.A.leaveB.leaves2.ThatIshallworkwithyou__agreatpleasure.A.areB.is3.Whatheleftme______someoldbooks.A.areB.is____________________________________________________________________________________★★★主語從句有時用“it”作形式主語，把真正的主語放在后面，以避免頭重腳輕。Thathewillcomehere

我不知道你會來這里。注意：that在從句中不充當(dāng)任何成分也無意義，在口語或非正式的文體中常常被省去。youwillcomehere.（that）Myunclesaid(that)Peterwouldcomeandthathewouldalsobringhisson.

有兩個或多個并列的賓語從句時,引導(dǎo)第二和以后幾個從句的that不可以省略.注意：在賓語從句中，表示“是否”既可以用whether,也可以用if.從句是否定句時一般用if。但下列情況只能用whether:1.與ornot連用;2.作介詞和discuss的賓語;3.后接動詞不定式時;4.用if引導(dǎo)會引起歧義.Pleasetellmeifyoulikeit.Canyoutellmewhethertogoortostay.1.請告訴我你是否喜歡它.(賓語從句,用whether好).2.如果你喜歡它就告訴我.(狀語從句).我不知道他來不來。我想知道他來還是不來。你們是在談?wù)撍欠褚獊韱?？他不在乎天氣是否好。Idon’tknowwhether/ifhewillcome.Iwanttoknowwhetherhewillcomeornot.Areyoutalkingaboutwhetherhewillcome?Hedoesn’tcareifitisn’tafineday.賓語從句中的否定轉(zhuǎn)移注意：如果賓語從句是由think,believe,imagine,suppose,expect等詞引導(dǎo)且主句主語是第一人稱，要將從句中的否定形式轉(zhuǎn)移到主句中去。反意問句由賓語從句決定。Ithinkhewon’tcomehere.()Idon’tthinkhewillcomehere.()我認為他不會來這里我認為他不會來這里,是嗎？Idon’tthinkhewillcomehere,__________?willheHedoesn’tthinkhecangoabroad,_______?doeshe注意：主句主語不是第一人稱時上述原則不適用。賓語從句中用it作形式賓語注意：如果主句中有形容詞或名詞作賓語補足語時，一般用it來作形式賓語，把從句放在賓補后面。這種情況that不可以省略.1)Wethinkthatweshouldhelpothersourduty.Wethinkit

goeswereplayinghavereturnedhadbeen表語從句(ThePredicativeClause)在復(fù)合句中起表語的作用。一般結(jié)構(gòu)是“主語+系動詞+表語從句”。可以接表語從句的系動詞有be,look,remain,seem等。另外,常用的還有thereasonwhy…isthat…和Itisbecause…等結(jié)構(gòu)。（1）我們的目的是他能認識到錯誤。Ourpurposeis________________________.hecanrealizehisfaults.that注意：引導(dǎo)表語從句的連接詞一般不省略。（2）問題是它是否值得做。Thequestionis_______________________whether

★★★★練習(xí)：同位語從句(TheAppositiveClause)在復(fù)合句中起同位語的作用。同位語從句一般放在如idea,news,fact,promise,suggestion,belief,truth等含有豐富內(nèi)涵的詞語后面，用來說明前面那個詞的具體內(nèi)容。他給了她一個承諾，他會在兩個月后回來。Hegaveherapromise______________________________________.hewouldcomebackintwomonthsthat一般說來，同位語從句都用that來作連接詞，而且不能省略。也可用how,when,where等。1.Theideathatcomputerscanrecognizehumanvoicessurprisesmanypeople.2.WordcamethatNapoleonhimselfwascomingtoinspectthem.3.ImetaproblemhowIcouldgetmydestination.4.Ihavenoideawhetherit’llraintomorrow.同位語從句中表示“是否”只能用whether.辨析：1.同位語從句與定語從句(1)Thenewsthatourteamhaswonthefinalmatchisencouraging.

Thenewsthatyoutoldusis

reallyencouraging.從句的作用不同：同位語從句用來進一步說明前面名詞的內(nèi)容；定語從句用來修飾、限定前面的名詞。

（定語從句）（同位語從句）(2)Thesuggestion

thatstudentsshouldlearnsomethingpractical

isworthconsidering.Thesuggestionthatisworthconsideringisthatthestudentsshouldlearnsomethingpractical.（同位語從句）（定語從句）引導(dǎo)從句的關(guān)聯(lián)詞that的功能不同：that引導(dǎo)同位語從句時是一個純連詞，不充當(dāng)任何成分且無意義；而引導(dǎo)定語從句的that是關(guān)系代詞，既指代先行詞又須在從句中充當(dāng)成分。

同位語從句——that不能省定語從句——that在從句中作賓語時，可以省(3)Ihaveheardthenewsthathevisitedourfactory.Ihaveheardthenews(that)hetoldyoutheotherday.說出下列從句屬于哪種從句：A:Appositive（同位語）;B:Attributive（定語）Hisproposalthatwegothereonfootisacceptable.Manyteachersholdtheviewthatteenagersshouldnotspendtoomuchtimeonline.3.Thefirstrequestthathemadewastoaskforfreedom.4.Doyouhaveanyideawherewewillbesent?5.Isthisthecompanywhereyourfatherworks?6.Thisisthereasonthathegaveforhisabsence.7.Hemadeanexcusethathiscarbrokedownon

WhatWhat

在名詞性從句中that不充當(dāng)成分只起連接作用，而what則在從句中作主語、賓語和表語。3.疑問詞＋ever可引導(dǎo)名詞性從句相當(dāng)anyonewho,anythingthat等，在從句中要充當(dāng)一定的成分。疑問詞＋ever還可引導(dǎo)讓步狀語從句，相當(dāng)于nomatter＋疑問詞。Whoeverbreaksthelawwillbepunished.

＝Anybodywhobreaksthelawwillbepunished.Parentsshouldn'tbuywhatevertheirchildrenwant.＝Parentsshouldn'tbuyanythingthattheirchildrenwant.Whereveryouare,youmustbehaveyourself.＝Nomatterwhereyouare,youmustbehaveyourself.4.名詞性從句中的虛擬語氣：（1）賓語從句中的虛擬語氣

在表示建議、要求、命令等動詞后的賓語從句要用虛擬語氣，其謂語動詞用動詞原形或“should+動詞原形”。常見的這類動詞有ask,advise,argue,arrange,determine,decide,command,insist,intend,move,prefer,propose,order,recommend,request,require,suggest(建議)，urge,demand,desire,direct等。e.g.Theyurgedthatthelibrary_____________openduringthevacation.(keep)

Hedemandedthathe______________therighttoexpresshisoption.(give)

(should)bekept(should)begiven（2）主語從句中的虛擬語氣主語從句中的虛擬語氣形式為“Itis+引起虛擬的形容詞或過去分詞+that主語從句（謂語動詞用原形或should+動詞原形）”。常用的這類形容詞有advisable,appropriate,crucial,desirable,essential,important,natural,necessary,preferable,strange,urgent,vital等，常用的過去分詞有desired,demanded,ordered,requested,suggested,advised,recommended,required等。

e.g.Itisdesiredthatwe_____________ourlessonbeforeclass.(preview)(should)previewItisessentialthattheprogram___________loadedintocomputer.(be)(should)be(3)表語從句和同位語從句中的虛擬語氣在表示建議、命令、主張、要求、愿望等名后面的表語從句和同位語從句中謂語動詞要求用虛擬語氣，其形式為“（should）+動詞原形”。常見的這類詞有resolution,pray,decision,motion,suggestion,preference,proposal,advice,recommendation,desire,demand,requirement,order,necessity,request,idea等。
