{Hisjobisimportant.Whathedoesisimportant.表语Thisishisjob.Thisiswhathedoeseveryday.

{宾语Idon’tlikehisjob.Idon’tlikewhathedoeseveryday.同位语Idon’tknowabouttheman,Mr.White.Idon’tknowaboutthefact

thatheisateacher.Whowillwinthematchisstillunknown.Iwanttoknowwhathehastoldyou.Thefactisthatwehavelostthegame.Thenewsthatwewonthegameisexciting.主语从句宾语从句表语从句

名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。同位语从句ObjectClauses

宾语从句

Iknowhim.2.Iknowwhoheis.主语谓语宾语（简单句）主语谓语宾语从句连词从句主语从句谓语

主句（复合句）句子做宾语就是宾语从句，跟在及物动词或介词后句子结构：主句+连词（引导词）+宾语从句。ConjunctionsofNounClauses(引导名词性从句的关联词):从属连词(不作成分）连接代词（作成分）连接副词（作状语）what,who,whom,whose,which,wh+everthat,whether,ifwhen,where,how,why一、连词（引导词）

1.that1.当宾语从句是由陈述句转变而来时（包括肯定句和否定句），连词由that引导，因为that在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略。LinTaofeels(that)hisownteamisevenbetter.

2.宾语从句中的连接词that在以下三种情况下不能省略：（1）当that从句与另一名词性从句并列作宾语时，第二个that不能省；（2）当that从句作介词宾语时，that不可省掉。（3）用it做形式宾语的宾语从句。当宾语从句是由一般疑问句变来时时，由连词whether或if引导，“是否”，不能省略。(1).Lilywantedtoknow___

hergrandmalikedthehandbag.(2).Let’ssee____

wecanfindoutsomeinformationaboutthatcity.(3).Sheaskedme---------

shecouldborrowthesebooks.注意whether和if的使用区别:1).whether和if都可以引导宾语从句

a.当有ornot时就用whether,不用if.Idon’tknowwhetherornotIwillstay.b.介词后面的宾语从句不能用if.

IworryaboutwhetherIhurtherfeeling.2.whether//ifif/whetherif/whetherif/whetherPracticetimeif/whether

1.Iaskedher____________shehadabike.

2.We’reworriedabout_________heissafe.

3.Idon’tknow_________heiswellornot.

4.Idon’tknow________ornotheiswell.

5.Idon’tknow__________Ishouldgo.

if/whetherwhetherwhetherwhetherwhether/if_______togo.whether3.当宾语从句是由特殊疑问句转变而来时，由疑问词（what,who,whom,which,whose

when,where,how,why等）引导，因为疑问词在从句中担任一定的句子成分，具有一定的意义，所以不可以省略。Doyouknow-----hesaidjustnow?Idon’tremember-------wearrived.Iaskedhim------

Icouldgetsomuchmoney.Pleasetellme-------wehavetosee.Doyouknow-------

timetheplaneleaves?whatwhenwherewho\whomwhatWethoughtit

thathewillnotgivein.注意：

it常可以放在动词think,find,consider,believe,feel,make等后作为形式宾语,真正的宾语-that从句则放在句尾.*________________________(我们觉得很奇怪)shedidn’tgotoschooltoday.Wethinkit

主语从句ConjunctionsofNounClauses(引导名词性从句的关联词):从属连词(不作成分）连接代词（作成分）连接副词（作状语）what,who,whom,whose,which,wh+everthat,whether,when,where,how,why1.————————————iscertain.（我们将迟到了）2.________________________isknowntoall.(地球是圆的)3.________________________isapity(你错过了这次机会)

ThattheearthisroundThatyoumissedthechance二whether是否，表不确定的事情.引导词Thatweshallbelate————————hurtshimsomuch.（她离开他）一.that

_---只起引导作用，不充当成分，但不能省略。没有意义

注意一:主语从句后置!为了避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.Thatweshallbelateiscertain.1.Thattheearthisroundisknowntoall.--2.Thatyoumissedthechanceisapity.--

Itisapitythatyoumissedthechance.It’sknowntoallthattheearthisround.--It’scertainthatweshallbelate.这样就构成了下面一些常用句型:

Itis+adj/nthat……(strange/apity…)Itis+v–edthat…..(…said/reported….由连词whether,连接代词what,who,which和连接副词when,where,why,how等引导,也常常后置:Whowilldoit____beendecided(have/has)Whatheneeds__thatbook.Whatheneeds__somebooks.√isare注意三：What与that引导主语从句what引导名词性从句时在从句中充当句子成分,如主语,宾语,表语,而that则不然,它在句子中只起连接作用。.(1)_____yousaidyesterdayisright.(2)_____sheisstillaliveisapuzzleWhatThat注意：主语从句中，谓语动词一般用单数注意二What引导的主语从句，可根据表语决定PredicativeClauses

表语从句从属连词(不作成分）连接代词（作成分）连接副词（作状语）what,who,whom,whose,which,wh+everthat,whether,asif/asthoughwhen,where,how,why.because表语从句是在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+系动词+表语从句”。可以接表语从句的系动词有be,look,remain,seem表语从句Thequestionis_____wecanrelyon

him.That’s_____wewereinneedofmoneyat

thattime.Helooked____hewasgoingtocry.That’s_____Iwaslate.whetherbecauseasifwhy注意：在表语从句中，表“是否”时，只能用“whether”不能用“if”。一般情况下，“that”不能省。
