高中英语 名词性从句第2课时

名词性从句2TeachingAims:1.学习表语从句，同位语从句基本考点。2.了解名词性从句的常考点并能融会贯通PredicativeClause

表语从句表语从句是在复合句中作表语的名词性从句。放在系动词be,look,seem，appear,taste,sound,remain等之后,一般结构是“主语+系动词+表语从句”。表语从句1连接词：that/whether/

who/whom/whose/which/what/when/where/why/how/asif/asthough/because2that/what:Ourplanis________we’llgothereonceaweek.That’s_______hesaid.that引导表语从句时，不充当句子成分，只起连接作用，无意义，不可省略。what引导表语从句时既起连接作用，又做句子主语或宾语或表语。thatwhat2.

Thequestioniswhether

wecanrelyon

him.表语从句中表“是否”，只能用________。3.Helookedasif

hewasgoingtocry.Ifeltasifwehadknowneachotherforyears.asif/asthough表“似乎”，有时会用虚拟语气。whether4.表语从句三个易混句式Ithinkit’sbecauseyouarecareless.Hewasill.That’swhyhewasabsent.Thereason________hewasabsentwas________hewasill.注意句型：This/Thatiswhy…“这/那就是……的原因”，why后面指的是事情的结果。This/That/Itisbecause…“这/那是因为……”，because后指的是原因。Thereasonwhy…isthat…“……的原因是……”,why引导的是reason的定语从句，that引导的是表语从句。whythat1.That’s___thePartycalledonustodo.A.whyB.whatC.howD.that2.Thereasonis___heisunabletooperatethemachine.A.becauseB.whyC.thatD.Whether3.Thatis___theyseparated.A.thatB.whatC.whichD.where4.Janeisnolonger___shewasfouryearsago.A.whatB.whichC.thatD.whenBCDAAppositiveClause

wherewearegoingtospendoursummervacation.总结：同位语从句对于名词进一步解释，说明名词的具体内容，常见的名词有fact,idea,news,truth,hope,doubt,suggestion,belief,evidence,information,thought,plan,story等一些有内容可说的名词。Thenewsthatourteamwonthefirstprizeexcitedallofus.ThefactthatPollydidn’taskfortheman’snameisapity.特点：对前面的名词作进一步的说明，无实际意义，不作任何成分，但不可以省略。1.关于that引导的同位语从句2.Mywishwillcometrueoneday_______Ishouldbuyabighouseformyparents.有时主句的谓语较短，而同位语从句内容较长，这是为避免“头重脚轻”，常常将谓语部分提到从句前面，形成分隔式同位语从句。that考点1：thatvs.what考点2:whatvs.whatever,whovs.whoever考点3：ifvs.whether考点4:同位语从句vs.定语从句考点5：名词性从句语序问题考点6：名词性从句时态问题名词性从句重要考点

考点1：thatvs.what________hesaidatthemeetingmadeusangry.________hesaidsomadeusangry.2.Acomputercanonlydo_________youhaveinstructedittodo.3.Amoderncityhasbeensetupin______wasawastelandtenyearsago.A.thatB.whichC.whatD.whereThatWhatWhat总结：that与what

的区别that只起连接作用，在句中不充当任何成分，无意义what

在从句中充当成分(主宾表)本身含有意义

(…的东西;什么；所…)做题技巧：判断从句是否缺少主宾表：如不缺少并且句意完整则填___________;如缺少主宾表之一，则填___________;如不缺主宾表而句意不完整，则填表达对应意义的连接副词，例：thatwhat1.Cindyshutthedoorheavilyandburstintotears.Nooneintheofficeknew_____shewassoangry.whereB.whetherC.thatD.why2.—IprefershuttingmyselfinandlisteningtomusicalldayonSundays.—That’s_____Idon’tagree.Youshouldhaveamoreactivelife.A.where B.howC.whenD.what

_________________等引导的名词性从句，一般泛指，译为任何…，相当于名词后加一个定语从句。

考点4：同位语从句vs.定语从句

Thenewsthatourteamwonthegameistrue.

----同位语从句

Thenewsthathetoldmeistrue.

----定语从句1.作用不同。

a.同位语从句位于名词之后，用来解释说明名词的具体内容，回答它是什么。常见的此类名词有：news,idea,fact,hope,promise,information,belief等.

b.定语从句是对先行词的修饰和限制，回答哪一个的问题。2.引导词及其在句中的作用不同。that引导同位语从句时，不充当成分，不可省略；that在定语从句中,充当从句的主宾表，作宾语时可省略，否则不可省。判断下列各句是什么从句：1.Thetruththattheearthturnsaroundthesunisknowntoall.2.Thenewsthatyoutoldmeyesterdaywasreallydisappointing.3.TheideathatIgetfromreadingthebookisofgreathelp.4.Thenewsthattheyhadwonthegamesoonspreadoverthewholeschool.同位语从句定语从句定语从句同位语从句考点5：名词性从句的语序

Sheaskedmewhenwewouldstarttomorrow.名词性从句的词序与陈述句语序相同，尤其注意那些由连接代词who(m),whose,which,what

和连接副词

when,where,why

等引导的名词性从句，不要受它们在特殊疑问句中用法的影响而误用疑问句词序。

1.Myvoicewassolittleandtheshopownerhadtobenddowntohear_______Iwantedtobuy.A.whatitwas B.itwasthat C.whatitwasthat D.whatwasthatC2.Marylooksupset.Iwonder____________withher.A.whatthematterisB.whatisthematterC.howisthematter D.howthematterisB考点6：时态问题1.

当主句的谓语动词是过去式时，宾语从句谓语动词一般用某种过去时态。如：Shesaid_______________________.

她说她不想知道。Iaskedher________________________.

我问她是否会同意。2.当从句表达的是客观事实，即使主句谓语动词用一般过去时，从句仍用一般现在时Yesterdaytheteachertoldusthatlight________(travel)fasterthansound.that

shedidn'twanttoknowwhethershewouldagreetravels3.

Idon’tknowwhenhe____________(come),butwhenhe____________(come),I’llcallyou.

when,if

这两个词既可引导名词性从句，也可引导状语从句。当它们引导名词性从句且表示将来意义时，要直接使用将来时态；但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。willcomecomesPractice1.Afterfivehours’drive,theyreached______they’dbeendreamingof.2.___________theearthisroundisknowntousall.3.Ourschoolisquitedifferentfrom_______itwasbefore.4.Fathermadeapromise______ifIpassedtheexaminationhewouldbuymeacomputer.5.Sarahhopestobecomeafriendof________sharesherinterests.6.Thereisnodoubtthat_____willbeourmonitoratlastisveryimportant.7.Thequestionis______thisbookisworthreading.Thatwhatthatwhatwhoeverwhowhether8.____youarenotfreetomorrow,I’llgowithoutyou.9.Heisabsentfromschool.Itis________heisseriouslyill.10.___hashelpedtosavethedrowninggirlisworthpraising.AWhoBTheoneCAnyoneD
