强调句型重点用法例析

强调句型重点用法例析巩勃英语中“Itis/was+被强调部分+who/that+其它”是强调句型的基本构成。这种结构在中学英语课本中频频出现，引起高考命题者的格外关注。强调句的基本句型是：“Itis/was+被强调部分+that/who从句。”可强调的句子成分通常为主语,状语,宾语等,不能用来强调谓语动词,表语(主语补语),定语，让步状语,条件状语等。被强调部分可以是单词，短语，也可以是从句。一、具体用法:强调句的基本构成：Itis/was+被强调的部分+who（主要指人时）/that+其余部分[注意1]这种结构可以强调句子的主语、宾语、状语（包括时间，地点，方式，原因等），但是不能强调谓语动词。原句的谓语动词如果是现在或将来时态，用Itis…that/who….；原句的谓语动词如果是过去时态，用Itwas…that/who….；强调时间、地点、原因或方式时不要用when,where或how,必须用that。[例句1]Isawhiminthestreetyesterdayafternoon.→ItwasIwhosawhiminthestreetyesterdayafternoon.（强调主语）→ItwasinthestreetthatIsawhimyesterdayafternoon.（强调地点状语）→ItwasyesterdayafternoonthatIsawhiminthestreet.（强调时间状语）→Itwashimthat/whoIsawinthestreetyesterdayafternoon.（强调宾语）[例句2]Hedidn’tgotobeduntilhismothercameback.→Itwasnotuntilhismothercamebackthathewenttobed.Hedidn’tdohishomeworkuntilhisfathercamebackfromwork.→Itwasn’tuntilhisfathercamebackfromworkthathedidhishomework.[例句3]Onlywhenyounearlylosesomeonedoyoufullyrealizehowmuchyouvaluehim.→Itisonlywhenyounearlylosesomeonethatyoufullyrealizehowmuchyouvaluehim.只有你快要失去某个人时，你才意识到你是多么尊重他。[例句4]Iwaslateagainbecausethetrafficwasveryheavyduringtherushhour.→ItwasbecausethetrafficwasveryheavyduringtherushhourthatIwaslateagain.强调句中只能强调由because引导的原因状语从句，because不能换成since,as,for,nowthat等。[注意2]强调句的疑问结构一般疑问句Is/Wasit+被强调部分+who/that…?特殊疑问句特殊疑问词+is/was+it+who/that…?Whatis/wasitthat…?Whois/wasitthat…?Whenis/wasitthat…?Whereis/wasitthat…?Whyis/wasitthat…?Howis/wasitthat…?[例句1]Isawhiminthestreetyesterdayafternoon.→Whenwasitthatyousawhiminthestreet?→Whowasitthatyousawinthestreetyesterdayafternoon?→Wherewasitthatyousawhimyesterdayafternoon?[例句2]Idon’tknowwhenhewillcomeback.→Idon’tknowwhenitisthathewillcomeback.（宾语从句疑问词后用陈述句语序）–HowwasitthatyougotintouchwithMr.Smith?你是怎么和Smith先生联系上的？–Troughafriendofmine.通过一个朋友。二、强调句型使用的场合强调句型用于强调陈述句。形式：Itis/was+被强调部分+that/who…例：（1）Itwasthere,thepolicebelieve,___shewasabletoactivatetherecordershekeptinherbag.A. untilB.whichC.thatD.when解析：选C被强调部分为地点状语there，thepolicebelieve为插入语（2）Itwasafterhegotwhathehaddesired___herealizeditwasnotsoimportant.A. thatB.whenC.sinceD.as解析：选A被强调的是时间状语afterhegotwhathehaddesired强调句型用于强调一般疑问句。形式：Is/Wasit+被强调部分+that/who…?例：Wasitformthelake___heoftenwentfishing___hesavedthedrowninggirl?A.that;thatB.where;whereC.where;thatD.that;where解析：选C解答此题关键是能够对句型进行正确的分析和判断。本题题干为一个强调句式，itwas+被强调部分+that/who，lake后面是个定语从句，由关系副词where引导，第二空才是强调句中的that。注意：如果该句型用于宾语从句中，应使用陈述语序。强调句型用于强调特殊疑问句。形式：疑问词（Wh-）+is/wasitthat+其他部分Ireallydon’tknow___Ihadmymoneystolen.A.whenwasitthatB.thatitwaswhenC.whereitwasthatD.itwaswherethat解析：选C强调句作know的宾语，语序应为陈述句语序，被强调部分为where，但是强调句为宾语从句时，这类wh-连接代词或副词常置于it之前，作宾语从句的连接词。注意：如果该句型用于宾语从句中，应使用陈述语序。强调句型用于强调not…until…句型形式：Itis/wasnotuntil+被强调部分+that+其他成分例:（1）Itwasnotuntilshegothome___Jenniferrealisedshehadlostherkeys.ItistwohoursthathespendsonEnglisheveryday.他每天花2个小时学英语。Itis2yearssinceIbegantolearnEnglish.自从我开始学英语已经两年了。C．强调句型与Itis/wasnotlongbefore…从句的区别：Itwastwoyearsbeforehecamebackfromabroad.Itwastwoyearslaterthathecamebackfromabroad.两个句子都意为“他是两年后回国的。”，第一句中的it指时间，before引导的是时间状语从句；第二句为强调结构、强调状语twoyearslater.。四、使用强调句型应注意的几点1.被强调的是状语或状语从句时要用that引导从句，而不能用which,when,where。例如：ItwasalongtheMississippiRiver____MarkTwainspentmuchofhischildhood.A.howB.whichC.thatD.where（答案为C）2.被强调的是人时，引导词可用who也可用that。例如：ItwasXiaoMingwho/thattookhisbagaway.3．被强调的不管是单数还是复数名词，主句的be动词都用单数is或was。例如：ItwasMadameCurieandherhusbandwhodiscoveredradium.4.被强调成分是主语，who／that之后的谓语动词应该在人称和数上与原句中的主语保持一致。如：ItisIwhoamright．Itishewhoiswrong．Itisthestudentswhoarelovely．5.如果被强调的成分有同位语，同位语也应提前。Itwasfromhim，hischemistryteacher，thatPaullearnedtowatchcarefullyinclass．6.被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格Itwashethathelpedmeyesterday.Itwasmethathehelpedyesterday.7.被强调部分既包括人又包括物，用that不用whoItwasthethingsandpeoplethattheyrememberedthattheyweretalkingabout．五、常见强调句型经典练习归类（一）强调句型的强调部分必须是对that/who之后句子的某一成分表示强调，如果把"Itis(was)...that"去掉，该句应该意思完整，不缺任何句子成分：1.Isit_____whowantstoseeyou.A.himB.heC.hisD.himself2.Itwas_____whorespectedalltheirteachers.A.themB.theirC.theyD.themselves3.---WhatisMary?---Wasit_____thatyouwerereferredto?A.heB.sheC.herD.they4.It_____MikeandMarywhohelpedtheoldmanseveraldaysago.A.wasB.areC.wereD.hadbeen5.It_____atChristmasthatJohnSmithgaveMaryahandbag.A.musthaveB.willbeC.mighthavebeenD.mayhavehad6.---Wasthatnewschoolmasterwhowalkedby?---_____.A.ItmustbethatB.ItmusthavebeenC.HemustbeD.Thismusthavebeen【题解】强调部分如果是人称代词，应根据句子需要选择它的主格或宾格形式：如第⒈⒉⒊小题。注意谓语动词形式与整个句子语境的一致性：如第⒋⒌⒍小题。（二）强调部分为疑问词时：7._____electricityplaysanimportantpartinourdailylife?A.WhywasitthatB.WhyisitthatC.WhyisitD.Whyitisthat8.Whowasit_____wantedtoseemejustnow?A.thatB.whoC.whenD.when9._____youmettheforeignerfromCanada?A.WhereitwasthatB.WhoitwasthatC.WherewasitthatD.Wherewasthat【题解】强调部分为疑问代词或疑问副词时，该强调句句型结构与特殊疑问句句型相同，即：疑问词+一般疑问句”（三）强调部分为"not...until"句型：10.Itwasnotuntillateintheevening_____herhusbandarrivedhome.A.whichB.whenC.thatD.how11.Itwasnotuntil1920_____regularradiobroadcastsbegan.A.whichB.whenC.thatD.since12.Itwasnot__shetookoffherdarkglasses__Irealizedshewasafamousfilmstar.A.when;thatB.until;thatC.until;whenD.when;then【题解】注意"not...until"句型的变化。比较下列三个句子：Shedidn'trememberherappointmentwiththedoctoruntilshehadarrivedhome.Itwasnotuntilshehadarrivedhomethatsherememberedherappointmentwiththedoctor.Notuntilshehadarrivedhomedidsherememberherappointmentwiththedoctor.（四）复合句中的强调句型：13.Ican'tquiteremember_____youstarteddoingthework.A.thatitwaswhenB.whenitwasthatC.whenwasitthatD.thatwasitwhen14.Shewantstoknowifitis600milesanhour_____thenewestplanecango.A.whichB.thatC.whenD.onwhich15.Wasit_____hewasseriouslyillthathedidn'tcometoschoolyesterday.A.althoughB.thatC.becauseD.since16.ItwasonlywhenIrereadhispoemsrecently_____Ibegantoappreciatetheirbeauty.A.untilB.thatC.thenD.so17._____hecamebackhomethatweknewwhathadhappened.A.WhenitwasB.ItwaswhenC.WasitwhenD.Whenwasit18.Itwasthetraining_____hehadasayoungman_____madehimsuchagoodengineer.A.what;thatB.that;whatC.that;whichD.which:that19.Itwas_____hesaid_____disappointedmeatthattime.A.what;thatB.that;thatC.what;whatD.that;what【题解】当强调部分为从句或含从句的短语时，应首先确定它在句子中的作用。第⒔⒕小题为宾语从句；第⒖⒗⒘小题为状语从句,此时不能对for,as,since,although引导的从句表示强调;第⒙小题的强调部分又被一个由which引导的定语从句修饰;第⒚小题的强调部分则为what引导的主语从句。（五）强调部分为介词短语：20.ItwasthroughJack_____MarygottoknowBob.A.whoB.whomC.howD.that21.Itwas_____greatcarethattheydidthejob.A.forB.aboutC.withD.in22.ItwasonOctober1st1949_____newChinawasfounded.A.whichB.whenC.asD.that23.Wasitinthispalace_____thelastemperordied?A.thatB.inwhichC.inwhereD.which24.Itwastheschoolgate______Imetanoldfriendofmineafterclass.A.thatB.whichC.whereD.why【题解】强调部分为介词短语时，①应特别注意能引起误解的干扰选项，如第20小题；②表示时间或地点时，应注意与定语从句的区别，如第24小题。25、（2011
