二、主语从句
一、主语是个句子,或者从句在句中充当主语
1.当主语是陈述句时,连接词是that即:
that(不省略)+该陈述句
Eg.1.)Thatwewillbelateiscertain.(Wewillbelate.)
2.)Thathedidnotcomeyesterdayisapity.(Hedidnotcomeyesterday.)
(注意)主语从句的that一定不能省略,而宾语从句中的that可以省略。
Eg.1.)Thatwewillbelateiscertain.(主语从句,that不能省略)
2.)Ihope(that)wewillwinthegame.(宾语从句,that可以省略)
2.当主语是一般疑问句时,连接词是whether(ornot)
即:
whether(ornot)+该一般疑问句的陈述语序
(注意)“if”不能引导主语从句,这要与宾语从句进行区分。
1.)Whetherhewillgothereisnotknown.(Willhegothere?
)
2.)Whethertheycanfinishthejob(ornot)isnotclear.(Cantheyfinishthejob?
)
3.当主语是特殊疑问句时,连接词是特殊疑问词“8W+H”
即:
特殊疑问词“8W+H”+该特殊疑问句的陈述语序
(注:
8W指的是what/where/which/who/whom/why/whose/when,H指的是how)
1)Whathedidyesterdayisnotknown.(Whatdidhedoyesterday?
)
2)Wherehewentyesterdayisnotclear.(Wheredidhegoyesterday?
)
3)Whichteamhelikedhasnotbeendecided.(Whichteamdidhelike?
)
4)Whowonthegameseemscertain.(Whowonthegame?
)
5)Whomhemetyesterdayisnotclear.(Whomdidhemeetyesterday?
)
6)Whyhewaslateforthemeetingistobefoundout.
(Whywashelateforthemeeting?
)
7)Whosebookthisisisnotclear.(Whosebookisthis?
)
8)Whenhewillarriveisnotknown.(Whenwillhearrive?
)
9)Howwewillhelpthelostboywillbediscussedatthemeeting.
(Howwillwehelpthelostboy?
)
二、主语从句后置
1.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.
1.)Thatwewillbelateiscertain.
--It’scertainthatwewillbelate.
2.)Whetherhewillgothereisnotknown.
--Itisnotknownwhetherhewillgothere.
3.)Wherehewentyesterdayisnotclear.
--Itisnotclearwherehewentyesterday.
2.It作形式主语常用句型:
(that引导的主语从句是真正的主语)
Itispossible/important/necessary/clearthat...
1)It’ssaid/reportedthat..据说/据报道…
2)It’sbeenannounced/declaredthat...已经通知/宣布…
3)Itseems/appears/happensthat…显然、明显、碰巧..
4)It’snowonderthat…并不奇怪/无疑…
3.主语从句中谓语动词一般用单数,What引导的主语从句,谓语动词根据表语决定
Whatheneeds_is_thatbook.Whatheneeds_are_somebooks.
4.What与that引导主语从句的区别
Eg.
(1)Whatyousaidyesterdayisright.(Whatdidyousayyesterday?
)
(2)Thatsheisstillaliveisapuzzle.(谜题)(Sheisstillalive.)
练习题

C.iswaterD.thatwaterto
三、宾语从句
一、宾语从句:
宾语是个句子,或者说从句在句中充当宾语
1.当宾语是陈述句时,连接词是that即:
that(可省略)+该陈述句
1.)Ihope(that)hewillcometomorrow.(Hewillcometomorrow.)
2.)Heguesses(that)thisteamwillwin.(Thisteamwillwin.)
(注意)主语从句的that一定不能省略,而宾语从句中的that可以省略。
1.)Thatwewillbelateiscertain.(主语从句,that不能省略)
2.)Ibelieve(that)wewillwinthegame.(宾语从句,that可以省略)
2.当宾语是一般疑问句时,连接词是whether(ornot)/if
即:
whether(ornot)/if+该一般疑问句的陈述语序
1.)Iaskwhether/ifTomknowsJack.(DoesTomknowJack?
)
2.)Idon’tknowwhether/ifhecamebackyesterday.(Didhecomebackyesterday?
)
3.当宾语是特殊疑问句时,连接词是特殊疑问词“8W+H”
即:
特殊疑问词“8W+H”+该特殊疑问句的陈述语序
(注:
8W--what/where/which/who/whom/why/whose/when,H--how)
1)Idon’tknowwhathedidyesterday.(Whatdidhedoyesterday?
)
2)Hewantstoknowwherehewentyesterday.(Wheredidhegoyesterday?
)
3)Hedidn’ttellmewhichteamheliked.(Whichteamdidhelike?
)
4)Wewanttoknowwhowonthegameatlast.(Whowonthegame?
)
5)Hismomaskedwhomhemetyesterday.(Whomdidhemeetyesterday?
)
6)Hedidn’tfindoutwhyhewaslateforthemeeting.
(Whywashelateforthemeeting?
)
7)Iamnotsurewhosebookthisis.(Whosebookisthis?
)
8)Theyaskmewhenhewillarrive.(Whenwillhearrive?
)
9)Wehavediscussedhowwewillhelpthelostboy.
(Howwillwehelpthelostboy?
)
1.当主句的谓语动词是command/demand/insist/order/require/suggest等表示要求或建议的动词时,从句谓语动词用(should)+动词原词,should可以省略
eg
(1)Sherequired(that)he(should)gobackhomerightnow.
Sherequired(that)hegobackhomerightnow.
(2)Isuggested(that)he(should)askhisteacherforhelp.
Isuggested(that)heaskhisteacherforhelp.
2.当主句中believe/expect/suppose/think等作谓语动词时,否定要前移
Eg.Idon’tthinkthathewillcometomorrow.(Hewon’tcometomorrow.)
Hedoesn’tbelievethatitistrue.(Itisnottrue.)
3.宾语从句从句的语序必须是陈述语序,即连接词+主语+谓语+其他成分
eg.Ibelievethattheywillcomesoon.HeaskedmewhetherIwasateacher.
Theywantedtoknowwhattheycandoforus.
4.宾语从句的时态受主句的限制
主句是一般现在时态,从句根据实际情况而定
主句是一般过去时态,从句用相应的过去的时态
如果从句的动作发生在主句之前,则从句要用过去完成时态
eg.1)Shesaysthatsheisastudent.
Shesaidthatshewasastudent.
2)ShesaysthatshewillflytoJapaninaweek.
ShesaidthatshewouldflytoJapaninaweek.
5.由whether或特殊疑问词8W+H引导的宾语从句
如果宾语从句的主语和主句的主语是同一对象,可以用“疑问词+不定式”做宾语的简单句结构
Idon’tknowwhatIshoulddonext.
Idon’tknowwhattodonext.
Hedidn’tknowwherehewouldlive.
Hedidn’tknowwheretolive.
Hewasn’tclearwhichwayheshouldgotoreachthebank.
=Hewasn’tclearwhichwaytogotoreachthebank.
6.含有宾语补足语时,若宾语是个句子,宾语通常用形式宾语it代替,真正的宾语放在宾语补足语之后
Eg.1)Wethinkitwonderfulthatwewillgoonatripthisweekend.(宾语是陈述句)
2)Ithinkituncertainwhetherwewillwinthegame.(宾语是一般疑问句)
3)Wehopeitdiscussedhowwewillsolvetheproblem.(宾语是特殊疑问句)

—Sorry,Ihavenoidea.A.howmuchdidshepayfor
B.howmuchwillshepayforC.howmuchshepaidfor
四、同位语从句
一、同位语从句通常跟在某些名词之后,用以说明或解释该名词表示的具体内容
可以跟同位语从句的名词通常有:
advice,fact,truth,decision,hope,idea,information,message,news,promise,proposal,reply,report,suggestion,word(消息),agreement(一致),problem,question,doubt,thought等。
ThenewsthatMr.LiwillbeournewEnglishteacheristrue.
有时同位语从句可以不紧跟在被说明的名词后面,而被别的词隔开
ThenewsistruethatMr.LiwillbeournewEnglishteacher.
1.当同位语从句是陈述句时,连接词是that即:
that(不省略)+该陈述句
Eg.1)ThenewsthatMr.LiwillbeournewEnglishteacheristrue.
2.)Headmittedthefactthathehadstolenthewallet.
(注意)that引导同位语从句时只是中心词和同位语从句之间的桥梁而已,无任何意义,也不充当任何成分,但that不可以省略
2.当同位语从句是一般疑问句时,连接词是whether(ornot)
即:
whether(ornot)+该一般疑问句的陈述语序(注意)此处不能用if.
1.)Hehasn’tmadethedecisionwhetherhewillgothere.
(decision的内容是Willhegothere?
)
2.)Theyhavenotcometoanagreementwhetherheshouldtakepartinthisgame.(agreement的内容是Shouldhetakepartinthisgame?
)
3.当同位语从句是特殊疑问句时,连接词是特殊疑问词“8W+H”
即:
特殊疑问词“8W+H”+该特殊疑问句的陈述语序
(注:
8W指的是what/where/which/who/whom/why/whose/when,H指的是how)
1.)Ihavenoideawhattheboyisdoinginthenextroomnow.
2.)Wehaven’tyetsettledthequestionwherewearegoingtospendoursummervacationthisyear.
3.)Wehavenotcometoaconclusionwhichteamisthebest.
4.)Thequestionwhoshoulddotheworkisbeingdiscussedatthemeeting.
5.)Thedoubtwhomhetalkedwithyesterdayisimportanttothecase(案件).
6.)Thedoubtwhyhedidnotcomeyesterdayisimportanttothecase(案件).
7.)Theproblemwhosemoneythisishasnotbeensolved.
8.)Ihavenosuggestionwhenhewillbeback.
9.)ThethoughtcametomehowIcansolvethisproblem.
二、that引导的同位语从句和定语从句的区别
1.意义不同:
that引导的同位语从句是用来进一步说明前面名词的内容,是解释中心词
that引导的定语从句用来修饰、限定前面的先行词,是修饰中心词(先行词)
Eg.①Thenewsthatourteamhaswonthefinalmatchistrue.
②Thenewsthathetoldusistrue.
[分析]①中that引导同位语从句,解释说明“news”的内容:
我们队取得了决赛胜利。
②中that引导定语从句,对“news”加以限定:
是他告诉我们的,而非来自其他渠道,起修饰作用。
2.that功能不同:
that引导同位语从句是一个纯连词,只是中心词和同位语从句之间的连接词,不充当任何成分;
that引导定语从句时,是关系代词,不仅起连接作用,而且还指代先行词并在从句中充当主语、宾语等成分。
Eg.①DadmadeapromisethathewouldbuymeaCDplayerifIpassedtheEnglishtest.
②.Dadmadeapromisethatexcitedallhischildren.
[分析]①中that引导同位语从句,其中that无词义,也不充当任何成分;
②.中that引导定语从句,that指代promise,又在从句中充当主语且that可以用which替换。
3.that可否省略:
that引导同位语从句时,不可省略。
在引导定语从句时,若在从句中作宾语,可以省略,若作主语则不可以省略。
Eg.①Thenewsthatourteamhaswonthefinalmatchistrue.
②Thenews(that)hetoldusistrue.
③Thenewsthatisfromthisnewspaperistrue.
①中that引导同位语从句,不能省略。
②.中that引导定语从句,that指代news,充当宾语,that可以用which替换,也可以省略。
③中that也是引导定语从句,that指代news,在从句中充当主语,that可以用which替换,但that不能省略。
4.有时同位语从句可以不紧跟在被解释说明的名词后面,而被别的词隔开。
定语从句有时也可以不紧跟在被修饰的先行词后面,而被别的词隔开。
Eg.①ThenewsistruethatanewteacherwillcometomorrowtoteachusEnglish.
②AnewteacherwillcometomorrowwhowillteachusEnglish.
(定语从句whowillteachyouEnglish修饰anewteacher,被willcometomorrow隔开,定语从句与先行词分离)
