C．whatD．how名詞性從句之主語從句一、名詞性從句概述：在句子中起名詞作用的各種從句統(tǒng)稱為名詞性從句。根據(jù)它們在句中的語法作用，這類從句又可分為主語從句、同位語從句、表語從句和賓語從句。二、主語從句定義：在句中起主語作用的從句稱為主語從句。引導(dǎo)主語從句的連接詞主要有：單純連詞(that,whether/if)、連接代詞(what,whatever,who,whoever,whom,whose,which,whichever等)和連接副詞(when,where,why,how,whenever,wherever,however等)。that引導(dǎo)的主語從句(1)由連詞that引導(dǎo)的主語從句:引導(dǎo)詞that無含義/在句中不做成分/不可以省。例如：Thatyouwillwinthemedalseemsunlikely.你能得獎(jiǎng)看起來不大可能。Thatlighttravelsinstraightlinesisknowntoall.眾所周知，光沿直線傳播。Thatyoudon,tlikehimisnoneofmybusiness.你不喜歡他不管我的事。(2)形式主語it替代主語從句位于句首，that引導(dǎo)真正的主語從句會(huì)放到句子的后面。常用的句式主要有如下幾種：1.It+系動(dòng)詞+形容詞+that從句。如：Itisnecessarythat…有必要……Itisclearthat…很清楚……Itislikelythat…很可能……Itisimportantthat…重要的是……類似的形容詞還有：strange;natural;obvious;true;good;wonderful;possible;unlikely;quite;unusual;certain;evident;worth-while;surprising;interesting;astonishing,etc.例如：Itwasreallyastonishingthatherefusedtotalktoyou.Itisessentialthatheshouldbeherebytheweekend.Itseemsobviousthatwecannotgoonlikethis.Itisnecessarythatyou(should)masterthecomputer.ItisimportantthatastudentlearnEnglishwell.It’sclearthattheybadlyneedhelp.Itislikelythatahurricanewillarrivesoon.知識(shí)拓展：在“Itisnecessary/important/surprising/strange/unthinkable/unbelievable/incredible+that從句”這類主語從句結(jié)構(gòu)中，從句中謂語動(dòng)詞常用(should)+動(dòng)詞原形”，形式，即要用虛擬語氣,should可省略。例如：Itisnecessarythatacollegestudent(should)masteroneortwoforeignlanguages.大學(xué)生掌握一兩門外語是有必要的。Itisstrangethatyou(should)trustJane.很奇怪你竟然相信簡。另外，需要注意的是，it作形式主語代替主語從句時(shí)，要注意和as引導(dǎo)的定語從句的區(qū)別。試比較：ItwasreportedthattheUSwasundertheterroristattack.Aswasreported,theUSwasundertheterroristattack.(2)常見用it作形式主語的復(fù)合句結(jié)構(gòu)It+系動(dòng)詞+名詞+that從句如：Itisafactthat…事實(shí)是 Itisgoodnewsthat………是好消息Itisaquestionthat………是個(gè)問題Itiscommonknowledgethat………是常識(shí)類似的名詞還有：apity；awonder；agoodthing； nowonder；surprise等。例如：Itisamysterytomehowitallhappened.Itiscommonknowledgethatthewhaleisnotafish.ItisnosurprisethatBobshouldhavewonthegame.It’sapitythatyoumissedthefilm.It+be+動(dòng)詞的過去分詞+that從句如:Itissaidthat…據(jù)說……Itisreportedthat…據(jù)報(bào)道……Ithasbeenprovedthat…已證明……Itmustbeprovedthat…必須指出 類似的過去分詞還有：known;estimated;expected;believed;thought;hoped;noted;discussed;required;decided;suggested;demanded;madeclear;foundout,etc.例如：Itisthoughtthatheisthebestplayer.Itisestimatedthatthevaseis2000yearsold.Ithasnotbeenmadeclearwhenthenewroadistobeopenedtotraffic.Itissaidthathewaskilledintheearthquake.+特殊詞+that從句。如：Itseems(happened/appears/doesn'tmatter/makesnodifference/occurred…)that…如：Itseemsthattheywillwinthegame.Itmakesnodifferencewhetherhewillattendthemeetingornot.ItdoesnotmatterifImissedmytrain.IthappenedthatIsawhimyesterday.用連詞whether引導(dǎo)的主語從句whether有含義“是否”在句中不做成分/不可以省。注意：引導(dǎo)主語從句，不能用if,只能用whether。例如：Whetheryoulikehimornotisnoneofmybusiness.Whetherwewillholdapartyintheopenairtomorrowdependsontheweather.Whethersheiscomingornotdoesn’tmattertoomuch.用連接代詞引導(dǎo)的主語從句在由連接代詞who,whose,whom,which,what,whoever,whomever,whichever,whatever引導(dǎo)的名詞性從句中，其連接代詞在句中起名詞性作用，擔(dān)當(dāng)一定成分.例如：Whatyouneedismorepractice.WhatIwanttoknowisthis.Whateverwedoistoservethepeople.注：whatever/whoever的功用whatever,whoever在主語從句中不含疑問意義。它引導(dǎo)主語從句，并在從句中作主語、賓語、表語等。whatever=anythingthat;whoever=anyonewho。要注意和whatever,whoever引導(dǎo)的讓步狀語從句的區(qū)別。如：Whoeverbreaksthelawshouldbepunished.（主語從句）（=Anyonewhobreaksthelawshouldbepunished.）Whoeverbreaksthelaw,heshouldbepunished.（讓步狀語從句）（=Nomatterwhobreaksthelaw,heshouldbepunished.）4）用連接副詞引導(dǎo)的主語從句用連接副詞when,where,why,how,whenever,wherever,however等引導(dǎo)的主語從句從句（其連接副詞有含義,在句中作狀語。）例如:Whereweshouldleaveitisaproblem.Whentheywillcomehasn’tbeenmadepubic.溫馨提示：如果主語從句是由連接代詞what,whatever,whoever等引導(dǎo)的，表示的是一個(gè)具體的東西或人時(shí)，這樣的主語從句不能用it作形式主語。Whatisworthdoingisworthdoingwell.Whateverwassaidherehasleftusmuchtoothink.Whoevercomeswillbewelcome.1）隨堂練習(xí)Itdoesn’tmatter
