（NounClausesastheSubject）

定義：用作主語的從句叫主語從句，它是名詞性從句之一。引導主語從句的連接詞有：連詞that,whether；連接代詞who,what和which；連接副詞when,where,how和why。編輯ppt主語從句：做主語用的名詞性從句，因其在復合句中做主語，又稱主語從句，引導主語從句的有連詞that，whether，連接代詞who，what，which，連接副詞when，where，how，why等。

編輯ppt1.連接詞：1）從屬連詞：that，whether等.that引導主語從句只起引導作用，本身無實際意義，在主語從句中不充當任何成分，但不能省略。

Thatshelefthimcuthimtotheheart.Thathewillcomeiscertain.編輯ppt2)連接代詞who，what，which,whatever,whichever,whoever

Whatseemseasytosomepeopleseemsdifficulttoothers.Whichsidewillwinisnotclear.由whether及其他連詞引導的主語從句放在句首，句后都可。

Whetheritwillpleasethemisnoteasytosay.編輯ppt3)連接副詞when，where，how，why等。Whyhediditremainsamystery.Whentheywillstartisnotknownyet.Howhebecameagreatscientistisknowntousall.2.位置：主語從句可以前置，也可以后置。用it做形式主語，而把主語從句，在句末，常用下面幾種句型。1）It+be+表語+主語從句表語：（名詞，形容詞，過去分詞）編輯pptItisstilluncertainwhetherheiscomingornot.ItisanhonourthatIwasinvitedtoattendthemeeting.Itisafact(ashame,apity,goodnews…)that…Itiscertainthatshewilldowellinherexam.ItistruethatItoldhereverything.ItissaidthatMr.GreenhasarrivedinBeijing.ItisreportedthatChinahassentanothermanmadeearthsatelliteintoorbit.編輯ppt2）It+不及物動詞+主語從句Itseemed(happened,doesn’tmatter,hasturnedout)that…

Ithappensthattheywereabsent.ItseemsthatAliceisnotcomingtothepartyatall.Itdoesn’tmatterwhethershewillcomeornot.Itmakesnodifferencewhereweshallhavethemeeting.編輯ppt3)It+及物動詞（被動語態(tài)）+主語從句IthasbeendecidedthattheexhibitionwillnotopenonSundays.注意:1）主語從句在句首時，必須由連接詞引導，不能省略這些連接詞；但是如果用it做形式主語，而把主語從句放在句末時，從屬連詞that可以省略。編輯ppt誤：Theyshouldlikeeachotherisnatural.正：Thattheyshouldlikeeachotherisnatural.正：Itisnaturalthattheyshouldlikeeachother.2)如果主語從句放在句首，不能用if引導，但是如果用it做形式主語，而把主語從句放在句末時，也可以用if引導.誤：IfMaryreallyheardhimisreallydoubtful.正：ItwasdoubtfulifMaryreallyheardhim.編輯ppt4).用于Itisimportant/natural/necessary/impossiblethat...句型中,主語從句應使用虛擬語氣,謂語動詞用\“should+動詞原形\”的形式,should有時可以省略。5)在It+be+suggested/advised/ordered/requested/insisted/required中,that從句的謂語也應該用\“should+動詞原形\”的形式,should有時可以省略。編輯ppt5.主語從句需注意的問題(1)主語從句中用陳述語序WhatsheisafraidofistheirtakinghertoParis.(Whatissheafraidof…Wrong)(2)主語從句后謂語動詞用第三人稱單數(shù)Thattheyhaven’tphonedisstrange.(3)that引導的主語從句中，that不可被省略Thatpricewillgoupiscertain.編輯ppt6.It作形式主語和it引導強調句的比較

It作形式主語代替主語從句，主要是為了平衡句子結構，主語從句的連接詞沒有變化。而it引導的強調句則是對句子某一部分進行強調，無論強調的是什么成分，都可用連詞that。被強調部分指人是也可用who/whom。例如：Itisapitythatyoudidn’tgotoseethefilm.Itdoesn’tinterestmewhetheryousucceedornot.

Itisinthemorningthatthemurdertookplace.ItisJohnthatbrokethewindow.編輯ppt7.what與that在引導主語從句時的區(qū)別what引導主語從句時在句時在從句中充當句子成分，如主語．賓語．表語，而that則不然。例如：1)Whatyousaidyesterdayisright.2)Thatsheisstillaliveisaconsolation.What在此引導主語從句,又做said的賓語That只起連接作用,不做成分編輯ppt1.Whereshallwespendtheholidayisn’tdecided.2.Youhavemadeamistakeisafact.3.Thatiscertainthatwecanwin.4.Nomatterwholeavestheroomlastoughttoturnoffthelights.5.Itisimportantthatastudentlearnsaforeignlanguage.weshallThatyouhaveItisWhoevershouldlearn改錯練習編輯pptDescribeyourmotherwithyourpartner.Suggestedstructures:Whatmymotherlikesis_________________.Whatmymotherdoesn’tlikeis_____________________Whethermymotherwouldfellhappyis_______________Whymymotherwouldbehappyis_________________Whymymotherfeelsupsadis______________________編輯ppt1.Ireadaboutitinsomebookorother,doesitmatter_______itwas?（01北京春季)
