名詞性從句解析及練習(xí)題

高名性句習(xí)在句子中起名詞作用的句子叫名詞性從句，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句成分為主語從句、表語從句、賓語從句和同位從句。一引名性句連詞、連接代詞：who,whom,。有詞義，在從句中擔(dān)任成分，如主、表語、賓語、或定語等。、連接副詞：where,why,。有詞義，在從句中擔(dān)任成分，作狀語。、連接詞：that,whether,if,if。that無義，在句中不擔(dān)任成分，有時可省略if(whether),asif雖詞義，但在從句中不擔(dān)任成分。二主從、主語從句在復(fù)合句作主語。e.g.Whowillisnotimportant.、用it作式主語，主語從句放句末。e.g.It’tsomuchwhetherwillornot.、that引主語從句時，不能省略。e.g.Thatsuddenlyfellilllastsurprised.注意：that從作主語和賓語時，可以用it替換成以下幾種結(jié)構(gòu)表達。Itisclear/certain/likely/true/surprisingthat…Itisaidea/nothat...Itissaid/reported/believed/known/thought/suggestedthat（D）Itthat…如：IthappenedthatIwentoutlastnight.ItissaidthatChinawillwininthe三表從、表語從句在復(fù)合句中作表語，位于系動詞之后。e.g.Thequestionwaswhocouldgothere.四賓從、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一可省略。e.g.I(that)everythingisallright.賓從句中的連接詞that有可省有時又不可省，在以下幾種情況中that不能略當(dāng)that從和主句謂語動詞之間有插入詞語或者從句主語之間有插入語時that不省略that從句與另一名詞性從句并列作賓語時，that不省）當(dāng)that介詞賓語時，that不省掉。如：Hejudgedthat,becausehewasachild,didnotunderstandwineEveryoneandthatshewasworried.reasonliesinthatshetheothersdo.、whether和if的法。）whether和if在語從句中可以互換，但是作介詞賓語時連接詞一般用whether。如：Itallonwhethertheywillback.）后面直接跟ornot時。：Ididn’twhetherornothadarrivedinWuhan.）主語從句、表語從句、同位語從句中只能用whether。如：themeetingwillbeputoffnotdecidedyet.questioniswhethertheymuchmoney.oughttodiscusscarefullythequestionwhetherwecandoitornot.）whether常or連表示一選擇if不這樣用questionofwhethertheyorfemaleisnotimportant.）whether也與詞不定式連用但if能。如：Inotwhethertogoor6）賓語從句提前時用不if：Thankbut’llbefree’mnotsureatthemoment.7）引導(dǎo)條件狀語從句時，必用Ifitrains,we’tgotoPalace.五同語句同位語從句在句中作某一名詞的位語般于名doubt、idea等后，說明該名詞的具體內(nèi)容。e.g.InohebeThehehadnotanythingsurprised注意:同語從句與定語從句中that區(qū)別。同位語從句中的連詞that只接作用從中不擔(dān)當(dāng)任何句子成分定句中的關(guān)系代在中做賓語或主語，賓語與先行詞有飾關(guān)系。如果句子是同位語從句，就應(yīng)用連that不能用同位語從句一般放在表具體含義的名詞后釋名詞的含義或內(nèi)容，如以下名詞、fact、plan、等，而定語從句只是對先行詞的限定和修飾。如Theyexpressedthehopethattheywouldcometoagain.Thesheexpressedistoagain.六疑詞+ever和nomatter+疑問的別①疑問詞+引導(dǎo)名詞性句，在主從句中要充當(dāng)一定的部分。如：Whoeverbreakstherulemustpunished.Youcanwhateveryoulikeintheshop.②疑問詞+可引導(dǎo)讓步語從句。如：Whoeverbreakstherule,bepunished,Whateveryoudo,youdoit③nomatter問詞只能引導(dǎo)步狀語從句。如：Nomatterwhatyoudo,youdoitNomatterwhothebepunished.七名性句主和句時一（1）賓語從句中主句和從句的態(tài)保持一致，但如果從句中表示提示的是客觀現(xiàn)象，雖然主句過去時態(tài)，從句仍用一般現(xiàn)在時。如：Hello,IdidnknowyouwereLondon.HowlongTheteachertoldusthattravelsatspeed.（2）主語從句作主語相當(dāng)于單第三人稱作主語，謂語動詞用單數(shù)，如果a連個或兩以上的主語從句作主語時，謂語動詞用復(fù)數(shù)；兩個或多個連接詞引導(dǎo)一個主語從句，謂語動詞用單數(shù)。如Whenthewill______notbeenWhenwheretheygo_______notbeendecidedyet.Whenandthebegin_______notdecided.八名性句詞名詞性從句在句中要用陳述句語。如：Hemewhatmatterwithme.Weheardthenewsthatthenewhouse.Whateveryousayinterestus九that和what的區(qū)that引導(dǎo)性從句時，在主句中不以當(dāng)任何句子成分，也沒有任何含義；導(dǎo)名詞從句時，在主從句中都要充當(dāng)一定主語、賓語表語或定語what的思:什,…的.Whatsurprisedmemostisherexpressiononherface.名性句項習(xí)一、判斷下列各句哪句含有名詞性從句，并指出是什么從句：Chinaisnolongerittobe.truththattheearthturnstheistoall.hepersuadedthetotheplanisinterestingtoall.newsthattheyhadwonthesoonspreadthewholeschool.newsthatyoutoldreallydisappointing.ThatisLuXuntolive.asifunderstoodwhattalkingabout.DotheteachertaughtEnglishatIwonderwhyrefusedinvitation.二、歷屆高考名詞性從句試題youtootherpeople.(87)A.ThatB.C.D.This2.Theynoideaatall____________.(87)A.wheregoneB.didhegoC.whichplacegoneD.he3._____________thelastoughttoturnoffthelights.()A.AnyoneB.personC.WhoeverD.4.graduationtosentto_______________.(88)A.whereisneededB.whereheC.ismostlyD.ishemostlyneeded5.Thesephotographswillshow_____________.()A.whatourvillagelooklikeB.whatourvillagelookslikeC.howourvillagelooklikeD.howourvillagelookslike6.Canthegoldring?()A.whereAliceputB.hadAliceputC.AliceputD.Aliceput7.inamillionyears.(91)A.whatmanwilllooklikeB.whatwilllooklikeC.manwilllooklikeD.lookwillmanlike8._____________theGameswillheldinBeijingisnotknown.(92)A.B.IfC.D.That9.Itworriedabit_____________hairwasturninggrey.()A.B.thatC.ifD.for10.don’tlikehimisnoneofbusiness.()A.B.C.ThatD.Whether11.hesaidatthemeetingpresent.(93)A.B.ThatC.ThefactD.Thematter12.He_____________fortheviolin.(93)A.didIB.IpaidC.howmuchdidID.howmuchIpaid13.—youremember—Yes,Ido,bycar.()A.B.whenC.thatD.if14.isfactthatEnglishisacceptedasaninternational()A.ThereB.ThisC.ThatD.It15.Sarahhopestofriendof_____________sharesherinterests.(95)A.B.C.D.matterwho16.wecan’tgetseemsbetterwehave.()A.What;whatB.What;thatC.That;thatD.That;17.’llgocampingtheweather.()A.IfB.WhetherC.ThatD.18.Itisgenerallyconsideredunwisetogivechild_____________heor(97)A.howeverB.whateverC.whicheverD.19.theaccidentisstillcompletemystery.()A.B.ThatC.D.Where20.Itwasmatterofwouldtaketheposition.()A.B.C.whomD.21.—Idrovetofortheairlast（A）Isthatyouhaddaysoff?()A.B.whenC.D.22.hashelpedtosavethedrowninggirlisworthpraising.()A.B.TheoneC.AnyoneD.Whoever23.ThesewildflowersspecialI_____________Itosavethem.()A.thatB.whichC.whicheverD.whatever24.’tunderstandfewerandstudentsinterestinherlessons.()A.That;whatB.What;whyC.D.that25.Whatthedoctorsreallydoubtis_____________mymotherwillrecoverfromtheserious(01)A.B.C.whetherD.whyisnopossibility___________winthefirstprizeinthematch
