1高一下学期重点语法：名词性从句自编资料建议打印出来，认真学习，一定受益匪浅英语中的三大从句：定语从句、名词性从句和状语从句。一、概念名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。二、名词性从句的种类（找出下面划线句子分别是什么名词性从句）1.Whenwewillstartisnotclear.2.Shewon’tbelievethathersonhasbecomeathief.3.Myideaisthatweshoulddoitrightnow.4.Ihadnoideathatyouwereherfriend.（1）主语从句：三种结构1.主语从句+谓语Thatshewillwinthematchiscertain.2.主语从句+形容词（名词词组、过去分词）+that从句ItisimportantthatweteensshouldlearnEnglishItissaidthatourschoolwillholdasportsmeeting3.It+seem(happen，appear等不及物动词)+that从句ItseemsthatKatyisnotcomingtothisparty.（2）宾语从句在句子中起宾语作用的句子叫宾语从句，宾语从句放在及物动词或介词之后作宾语。宾语从句的结构主句+连接词(引导词)+宾语从句Idon'tknowwhyheisalwayslateforschool.Weallagreewithwhatyousaidatthemeeting.（3）表语从句表语从句位于连系动词后,有时用asif引导。结构为:主语+系动词+that从句1.be,look,remain,等系动词后均可跟表语从句：Mysuggestionisthatweshouldgoshopping.2.asif也可引导表语从句。Itlooksasifit’sgoingtorain.3.thereasonwhy…isthat…和Itisbecause…等结构。①Thereasonwhyhewaslatethismorningisthattherewasalotoftrafficontheroad.②ItwasbecauseIgotuplate.（4）同位语从句同位语从句在句中作同位语，它一般要放在主句中某些名词的后面，说明这些名词的含义。可跟同位语从句的名词主要有：fact,news,promise,reason,idea,hope,word,belief等。Beijing,thecapitalofChina,ismyhometown.Weheardthenewsthatourteamhadwon.Wewerehappytohearthenewsthatwasannouncedbyourboss.同位语从句的简易判断方法：我们可以在名词和从句之间加be,使之构成一个新句子，如果合乎逻辑，句子通顺，则是同位语从句，定语从句是不能用系表结构把先行词与从句连接起来的。eg:Thebeliefthattheearthisflatisstillheldinsomecountries.判断：定语从句,同位语从句1.ThefactthatGreatBritainismadeupofthreecountriesisstillunknowntomany.2.Thenewsthatisspreadingaroundtheairportiscoming.3.Thesuggestionthatstudentsshouldlearnsomethingpracticalisworthconsidering.4.Weexpressedthehopethattheyhadexpressed.5.WeexpressedthehopethattheywouldcometoChinaagain.Key:1同谓语从句2定语从句，that充当主语代替先行词3同位语从句4定语从句，that充当宾语5同位语从句三、名词性从句的引导词：1.连接词：that、if、whether（不充当句子成分）2.连接代词：who、whom、whose、what、which（充当句子成分）3.连接副词：when、where、why、how（充当状语）四、名词性从句考点归纳:考点1：连接词：that与what的区别1.______hewantsisabook.22.______hewantstogothereisobvious.3.Theresultis______wewonthegame.4.Thisis_____wewanttoknow.5.Is_____hetoldustrue?6.Weshouldpayattentionto______theteacherissaying.7.Ihavenodoubt_____hewillcome.8.Ihavenoidea_____hedidthatafternoon.归纳总结：Key1what2That3that4what5what6what7that8what考点2.区别if与whether1.Idon’tknow__________I’llbefreetomorrow.2.Theargument_______we’llhaveasportsmeetremainstobesettled.3.Thequestionis_______thisbookisworthwriting.4.Itdependson_______wewillhaveenoughmoney.5._______theycandoitmatterslittletous.6._____youarenotfreetomorrow,I’llgowithoutyou.7.Hedoesn’tknow________tostayornot.请你归纳：只能使用whether的情况：Key1whether/if2whether3whether4whether5whether6whether7whether考点3.what,whatever,who,whoever___________________等引导的名词性从句不含有疑问意义，相当于名词后加一个定语从句，而____________等引导的名词性从句含有疑问意义。1.__________wassaidheremustbekeptsecret.2._______weneedismoretime.3._______hastakenawaymybagisunknown.4._________breaksthelawwillbepunished.Key1What2What3Who4Whonomatterwho/what与whoever/whatever考例1:Itisgenerallyconsideredunwisetogiveachild_______heorshewants.A.howeverB.whateverC.whicheverD.whenever归纳总结：KeyBNomatter+疑问词不能引导名词性从句。考点4：it作形式主语,形式宾语it作形式主语翻译：1.他犯了那样一个错误真是遗憾。___________________________isapity.2.他来不来不重要。________________________doesn’tmatter.Key1Thathemadesuchamistakeisapity.=Itisapitythathemadesuchamistake.2Whetherhewillcomeornotdoesn’tmatter.=Itdoesn’tmatterwhetherhewillcomeornot.用it作形式主语的结构(1)Itis＋名词＋从句Itisafactthat…事实是…Itisanhonorthat…非常荣幸Itiscommonknowledgethat…是常识(2)Itis＋形容词＋从句Itisnaturalthat…很自然…Itisstrangethat…奇怪的是…(3)Itis＋不及物动词＋从句Itseemsthat…似乎…Ithappenedthat…碰巧…Itappearsthat…似乎…(4)It＋过去分词＋从句Itisreportedthat…据报道…Ithasbeenprovedthat…已证实…Itissaidthat…据说…it作形式宾语(1)make/find/feel/consider/thinkit+adj/n+that…/todo…(2)it指代后面从句所叙述的内容,常用like/dislike/love/hate/appreciate/make+it+if或when从句Ilike___intheautumnwhentheweatherisclearandbright.3A.thisB.thatC.itD.oneKeyC考点5语序问题(陈述语序，主语在前，谓语动词在后)1.Thephotographswillshowyou_______．A.whatdoesourvillagelooklikeB.whatourvillagelookslikeC.howdoesourvillagelooklikeD.howourvillagelookslike2.Youcanhardlyimagine______whenheheardthenews.A.howhewasexcitedB.howwasheexcitedC.howexcitedhewasD.hewashowexcited3.Heasked_______foraviolin.A.didIpayhowmuchB.IpaidhowmuchC.howmuchdidIpayD.howmuchIpaid4.Thephotographswillshowyou_______.A.whatdoesourvillagelooklikeB.whatourvillagelookslikeC.howdoesourvillagelooklikeD.howourvillagelookslikeKey1B2C3D4B挑战高考2011重庆22Itisstillunderdiscussion__________theoldbusstationshouldbereplacedwithamodernhotelornot.A.whetherB.whenC.whichD.where〖09重庆〗Weshouldconsiderthestudents’request___theschoollibraryprovidemorebooksonpopularscience.A.thatB.whenC.whichD.where〖08重庆〗PeopleinChongqingareproudoftheyhaveachievedinthepasttenyears.A.thatB.whichC.whatD.how〖10浙江〗.Itisuncertainsideeffectthemedicinewillbringabout,althoughabouttwothousandpatientshavetakenit.A.thatB.whatC.howD.whetherKey1A2A3C4B同学们，快通过题目测试一下，自己掌握得怎样？名词性从句1.Itdependson________wehaveenoughmoney.A.ifB.whetherC.ifornotD.what答：B。在主语从句、表语从句、同位语从句、让步状语从句、不定式前或介词后一般用whether，不用if。2.Wediscussed________weshouldmakehimmonitor.A.ifB.whetherC.thatD.what答：B。在discuss动词后一般用whether，不用it。3.Seeingmesopale,heaskedme________.A.whatwasthematter
