一．主語從句

主語從句是在復(fù)合句中充當(dāng)主語的從句，通常放在主句謂語動(dòng)詞之前或由形式主語it代替，而本身放在句子末尾。

一般主語從句

It作形式主語1.Thatanyonewantstokillherwasunbelivable.2.Whethertheworkcanbefinishedontimeisdoubtful.3.Whotheletterwasfromisstillunknown.4.Whytheysuddenlydisappearedstillremainsamystery.6.Itisapitythatyoudidn’tgotoseethefilm.7.Itissaidthatthecathasfourfingers.

1)______yousaidyesterdayisright.2)______sheisstillaliveisagoodthing.Itisrightwhatyousaidyesterday.Itisagoodthingthatsheisstillalive.WhatThat

二．賓語從句

賓語從句就是在復(fù)合句中作賓語的從句，通常放在主句謂語動(dòng)詞(及物動(dòng)詞)或介詞之后。賓語從句中that可以省略1.作動(dòng)詞的賓語

(1)由that引導(dǎo)的賓語從句(that通?？梢允÷?,例如：

Oursuccessdependsuponhowwellwecancooperatewithoneanother.

三．表語從句

表語從句在復(fù)合句中作表語的名詞性從句，放在系動(dòng)詞之后，一般結(jié)構(gòu)是“主語＋系動(dòng)詞＋表語從句”。be動(dòng)詞感官動(dòng)詞feelsmelllooksoundtaste保持keepstayremain變得

gobecomegetturn似乎seemappear系動(dòng)詞OnegreatstrengthoftheInternetisthatitprovidesinformation.Sothatiswhattheydid.Thedoctor’srequestisthatyoulieinbedforafewdays.

四．同位語從句

1)Theking’sdecisionthattheprisonerwouldbesetfreesurprisedallthepeople.2)Theorderthatallthesoldiersshouldstaystillisgivenbythegeneral.

同位語從句就是在復(fù)合句中作名詞的同位語的名詞性從句。同位語從句對(duì)于名詞進(jìn)一步解釋，說明名詞的具體內(nèi)容，一般由that引導(dǎo)同位語從句有時(shí)可以不緊跟在它所說明的名詞后面，而是被別的詞隔開。

HegotthenewsfromMarythatthesportsmeetingwasputoff.

3.同位語從句與定語從句的區(qū)別(1)定語從句中的that既代替先行詞，同時(shí)以在從句中作某個(gè)成分（主語或賓語），而同位語從句中的that是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。(2)定語從句修飾限定先行詞；同位語從句對(duì)名詞進(jìn)行具體內(nèi)容的補(bǔ)充說明?！?..的”1)ThenewsthathetoldmeisthatTomwouldgoabroadnextyear.2)ThenewsthatTomwouldgoabroadistoldbyhim.同位語從句定語從句成分that不做成分that主，賓，表作用解釋說明對(duì)先行詞起修飾作用，“…的”省略that不能省that在從句中做賓語時(shí)，可以省that在同位語從句 與定語從句的區(qū)別（I）試比較下面兩個(gè)例句:1.Thesuggestionthatheraisedatthemeetingisverygood.2.Thesuggestionthatthestudentsshouldhaveplentyofexerciseisverygood.（that引導(dǎo)定語從句,作賓語,可以省略）（that引導(dǎo)同位語從句,在從句中不擔(dān)當(dāng)任何成分，但不可以省略）

辨別下列從句是定語從句還是同位語從句1.Weheardthenewsthatourteamhadwon.2.Wemustfacethefactthatwehadspentallourmoney.3.Thenewsthathetoldmeyesterdaywasfalse.4.Thefactisthatwehavespentallourmoney.同位語從句同位語從句定語從句表語從句一．辨別下列名詞性從句的類別：1.Howthebookwillselldependsonitsauthor.2.JohnsaidthathewasleavingforLondononWednesday.3.Thefactisthathehasnotbeenseenrencently.4.Thefactthathehasnotbeenseenrencentlydisturbseveryoneinhisoffice.5.HewilltalktousaboutwhathesawinU.S.6.ItisimpossiblethatIgoandattendthemeeting.7.Whetherhewillgothereisnotknown.8.Whathesaidisnottrue.9.Whoevercomesiswelcome.
