高二英語寒假專題——名詞性從句精講精練人教版【本講教育信息】一、教學內(nèi)容寒假專題：名詞性從句精講精練名詞往往在句中充當主語，賓語，表語和同位語。在復合句中，代替名詞充當主語，賓語，表語和同位語的句子統(tǒng)稱為名詞性從句。名詞性從句分為：主語從句、賓語從句、表語從句、同位語從句。（一）引導名詞性從句的連接詞引導名詞性從句的連接詞可分為五類：a.連詞：that（無任何詞意，不作成分，只起連接作用，賓語從句中?？墒÷裕?)Myhopeisthatshewillsoonbewellagain.(表語從句)我的希望是她能很快康復。2)Everybodyhopesthatshewillsoonbewellagain.（賓語從句）大家都希望她能很快康復。3)Thatshewillsoonbewellagainisourhope.（主語從句）她能很快康復是我們的希望。b.whether,if（均表示“是否”表明從句內(nèi)容的不確定性，不作成分）1)Whetherheiscomingornotdoesn’tmattertoomuch.(主語從句，不能用if)2)Iwentinandaskedif/whethertheyhadacheapsuit.3)Iwonderwhether/ifhewillcomeinsuchbadweather.c.連接代詞：what,whatever,which,whichever,(在從句中作主語，賓語，表語，指物)1)____heneedismoretime.顯然，主語從句：he是主語，謂語動詞need缺賓語，因此應填what.2)Tellus___yousawandheardduringyourvisittothatuniversity.3)Thisisnot___Iwant.4)____somepeopleareagainstis___otherpeoplearefor.5)Thequestioniswhichteamwillwin.6)Ihavetwoapples,Idon’tknowwhichyouwant.歸納：what一般用于不知道內(nèi)容或范圍的句子；which“哪一個……”一般用于給出內(nèi)容或范圍的句子?？勺髦髡Z，賓語，表語，還可作定語。d.who,whoever,whom,whomever,whose（在從句中作主語，賓語，表語，定語，指人）1)Whowillgiveusalectureisunknown.2)Thequestioniswhowillcomehere.e.連接副詞：when,where,how,why,whenever,however,wherever(在從句中作狀語)1)Ihavenoideahowhelearnedaboutit.2)Whereshehasgoneisnotknownyet.3)Whenhewillstartisnotknownyet.4)Thisiswhyheislate.注意：連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用，在從句中充當從句的成分。（二）具體分類一）主語從句在復合句中作主語的從句叫主語從句。1)Thatyouareleavingisapity.你要走，真遺憾。2)Whetherthefootballgamewillbeplayeddependsontheweather.足球比賽是否舉行將視天氣而定。3)Whathewantstotellusisnotclear.他要跟我們說什么，還不清楚。4)Whowillwinthematchisstillunknown.誰能贏得這場比賽還不得而知。5)WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.英語晚會將在哪里舉行，還沒有宣布。6)Itisknowntoushowhebecameawriter.我們都知道他是如何成為一名作家的。有時為避免句子頭重腳輕，常用形式主語it代替主語從句作形式主語放于句首，而把主語從句置于句末。主語從句后的謂語動詞一般用單數(shù)形式。常用句型如下：（1）It+be+名詞+that從句①It’sapitythatwecan’tgo.很遺憾我們不能去。②ItisafactthatEnglishisbeingacceptedasaninternationallanguage.英語正在被人們接受為國際語言，這是事實。③Itisnowonderthatheisnothungry;hehasbeeneatingsweetsallday.難怪他不餓，他整天在吃糖果。（2）It+be+形容詞+that從句①Itiscertainthatshewilldowellintheexam.毫無疑問她考試成績會很好。②Itisprobablethathetoldhereverything.很可能他把一切都告訴她了。③Isittruethatthescientistwillgiveusalecture.下周那位科學家將給我們作報告是真的嗎？（3）It+be+動詞的過去分詞+that從句①ItissaidthatMr.GreenhasarrivedinBeijing據(jù)說格林先生已經(jīng)到了北京。②ItisreportedthatChinahassentanotherman-madeearthsatelliteintoorbit.據(jù)報道中國又成功地將一顆人造地球衛(wèi)星發(fā)射進入軌道。（4）It+不及物動詞+that從句①ItseemsthatAliceisnotcomingtothepartyatall.愛麗絲似乎不來參加晚會。②IthappenedthatIwasoutthatday.碰巧那天我外出了。（5）其他情況①Itdoesn’tmatterwhethershewillcomeornot.她是否來無關緊要。②Itmakesnodifferencewhereweshallhavethemeeting.我們在哪里開會毫無區(qū)別。③Itsuddenlyoccurredtoherthatshehadforgottentolockthedoor.她突然想到,她忘記鎖門了。另注意：在主語從句中用來表示驚奇、不相信、惋惜、理應如此等語氣時，謂語動詞要用虛擬語氣“(should)+do”，常用的句型有：a.Itisnecessary(important,natural,strange,funny,surprisingetc.)that…Itisimportantandnecessarythatwe(should)keepthebalanceofnature.我們要維持生態(tài)平衡，這很重要而且是必不可少的。b.Itisapity(ashame,nowonder,etc.)that…Itisapitythatyou(should)misssuchagoodchance.真遺憾你竟然失去這么好的機會。c.Itissuggested(requested,proposed,desired,etc.)that…It’ssuggestedthatwe(should)dotheexperimentasecondtime.有人建議我們再做一次實驗。Exercises:1.____ispowerisafamoussayingknowntousall.A.Whatknowledge

D.Why;because答案：1.C2.A3.D4.B5.B6.A二）表語從句在復合句中作表語的從句叫表語從句。其基本結構為：主語+系動詞+that從句。表語從句位于連系動詞后，可接表語從句的連系動詞有：be,look,seem,sound,appear，remain等。1)Thefactisthatwehavelostthegame.事實是我們已經(jīng)輸了這場比賽。2)That’sjustwhatIwant.那正是我想要的。3)Thequestioniswhethertheywillbeabletohelpus.問題是他們能否幫我們。【注意】whether可引導表語從句，但與之同義的if卻通常不用于引導表語從句。4)Thisiswhereourproblemlies.這就是我們的問題所在。5)Thatiswhyhedidn’tcometothemeeting.那就是他不到會的原因。asif/asthough也可以用在連系動詞后，引導表語從句。1)Itlooksasifitisgoingtorain.看上去天要下雨了。2)Atthattime,itseemsasifIcouldn’tthinkoftherightwordanyhow.當時，我似乎怎么也想不出一個恰當?shù)淖盅蹃?。注意：當主語是reason時，表語從句要用that引導而不是because。例如：Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning.because,why引導的表語從句1)That’sbecausehedidn’tunderstandme.那是因為他沒有理解我。（That’sbecause...強調(diào)原因）2)That’swhyhegotangrywithme.那正是他對我生氣的原因。（That’swhy...強調(diào)結果）使用虛擬語氣的表語從句在表示建議、勸告、命令含義的名詞后的表語從句，謂語動詞需用“should+動詞原形”表示，should可以省略。常見的詞有：advice,suggestion,order,proposal等。1)Mysuggestionisthatwe(should)startearlytomorrow.我的建議是我們明天一早就出發(fā)。2)Hisproposalwasthatthey(should)challengetheotherclassestoafriendlycompetition.他的提議是挑戰(zhàn)別的班級進行一場友誼競賽。1.Goandgetyourcoat.It’s___youleftit.A.there

D.how答案：1.B2.A3.A4.B5.A6.A7.D8.B三）同位語從句（1）同位語從句用于對前面的名詞作進一步的解釋，說明其前面的名詞的具體內(nèi)容。同位語從句通常由that引導，但也可以由連接代詞whether和連接副詞引導。1)Theywereallverymuchworriedoverthefactthatyouweresick.對你生病這件事，他們都很焦慮。2)Wehaven’tyetsettledthequestionwherewearegoingtospendoursummervacation.到哪去度暑假，這個問題我們還沒有解決。3)Thequestionwhetherweneedmoretimetodotheworkhasn’tbeendiscussed.我們是否要更多的時間來做這項工作，這個問題還未解決。（2）可用于同位語從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：1)Thenewsthatwewonthegameisexciting.我們贏得這場比賽的消息令人激動。2)Theproblemwhetherweshouldcontinuetodotheexperimenthasbeensolved.我們是否該繼續(xù)做這項實驗，這個問題已經(jīng)解決了。3)Ihavenoideawhenhewillcomebackhome.我不知道他什么時候回家。注意：當含有同位語從句的主句的謂語部分過短時，可以把謂語動詞提前，使同位語從句與名詞隔開，以避免頭重腳輕的現(xiàn)象。1)ThethoughtcametohimthatMaryhadprobablyfallenill.他想到的是瑪麗可能生病了。2)WordcamethatMr.Presidentwouldcomeandinspectourschoolhimself.有消息說總統(tǒng)先生將親自來視察我們學校。（3）使用虛擬語氣的同位語從句在一些表示“建議、勸告、命令”含義的名詞后的同位語從句中，謂語動詞需用“should+動詞原形”表示，should可以省略。1)Thisisourrequestthatthis(should)besettledassoonaspossible.盡快解決這個問題，這是我們唯一的要求。2)Hemadethesuggestionthatwe(should)gobytrain.他建議我們坐火車去。（4）有時可用namely,thatistosay,inotherwords,thatis,.(=thatis),forexample等引出同位語，說明其前面的名詞或代詞。1)Hetoldusthegoodnews,namely,themuseumisopentoall.他告訴了我們這個好消息：博物館對外開放了。2)ThereisonlyonewayofimprovingyourEnglish,thatis,topracticemore.要提高你的英語水平只有一個辦法，那就是多練。對比與用法同位語從句和定語從句的區(qū)別：①that引導定語從句時，為關系代詞，代指先行詞，有實際意義，在句子中充當句子成分，作賓語時可以省略；定語從句對名詞加以限制。②that引導同位語從句時，起連詞的作用，沒有實際意義，不充當句子成分，一般不能省略。同位語從句對名詞加以補充說明。試比較下面兩個例句:1)Ihadnoideathatyouwerehere．（that引導同位語從句，不能省略）2)Thenews(that)youtoldmeyesterdaywasreallydisappointing.（that引導定語從句，作賓語，可以省略）Exercises:isknowntousall,Williamhadbrokenhisword___hewouldgiveTomarise.A.As;that
