illagelookslike,分析:在名词性从句中,除了关联词要提到句首之外,一律要用陈述句语序。当关联词含疑问意义时,有的学生就会受习惯影响错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。本题句子的意思是:这些照片会告诉你我们村子是什么样。本题中根据引导词what要作介词like的宾语,而副词how不能作介词like的宾语,所以首先排除C、D,而A项是疑问句语序,故只能选B。,48,考点之四:考查名词性从句中的whether,if以及that的区别考例1:_wellgocampingtomorrowdependsontheweather.A.IfB.WhetherC.ThatD.Where分析:句子的意思是:我们明天是否去野营要视天气而定.whether与if当是否讲时的区别是:在引导宾语从句时两者可以互换,但在引导主语从句、表语从句和同位语从句以及介词后面的宾语从句或后面紧跟ornot时通常只能用whether,而不能用if.考例2:Whatthedoctorsreallydoubtis_mymotherwillrecoverfromtheseriousdiseasesoon.A.whenB.howC.whetherD.why分析:本题句子的意思是:医生真正怀疑的是我母亲是否能很快从重病中恢复过来.whether引导的是表语从句.,49,考例3:Itworriedherabit_herhairwasturninggray.A.whileB.thatC.ifD.for分析:本题句子的意思是:头发变白使她有点儿不安。It作形式主语,that引导的是主语从句。whether,if以及that引导的名词性从句的区别是:whether与if(当是否讲时)引导的名词性从句含有疑问意义;而that引导的名词性从句不含有疑问意义。,50,考点之五:考查名词性从句中的疑问词+ever引导的名词性从句及其与nomatter+疑问词引导的从句的区别考例1:Itisgenerallyconsideredunwisetogiveachild_heorshewants.A.howeverB.whateverC.whicheverD.whenever分析:本题句子的意思是:一般认为孩子要什么就给什么是不明智的.whatever引导的是宾语从句,A.however和D.whenever是不能作宾语的;而C.whichever表示无论哪一个、无论哪些,表示在一定范围内的人或事物,此处并不涉及一定范围内的人或事物,所以也不能选.,51,考例2:Sarahhopestobecomeafriendof_sharesherinterests.A.anyoneB.whomeverC.whoeverD.nomatterwho分析:本题句子的意思是:萨拉希望跟自己有共同爱好的人交朋友.疑问词+ever引导的名词性从句与nomatter+疑问词引导的从句的区别是:前者既可以引导名词性从句也可以引导让步状语从句;后者只能引导让步状语从句.首先排除D.而选A.anyone则应在其后加who.从句中需要的是主语,所以whomever也不行.,52,考点之六:考查名词性从句的虚拟语气问题考例:Itisnecessarythatacollegestudent_atleastaforeignlanguage.A.mastersB.shouldmasterC.masteredD.willmaster分析:本题选B.句子的意思是:大学生至少应该掌握一门外语。Itisnecessary-that用should的虚拟语气.(1)在主语从句中用来表示惊奇、不相信、惋惜、理应如此等,谓语动词用虚拟语气(should)+do,常用的句型有:I.Itisnecessary(important,natural,strange,etc.)that.II.Itisapity(ashame,nowonder,etc.)that.III.Itissuggested(requested,proposed,desired,etc.)that.如:Itisstrangethatshe(should)thinkso.,53,(2)表示建议、请求、命令、要求、坚持等及物动词后面的宾语从句中要用虚拟语气,常用的这类动词有suggest,propose,insist,desire,demand,request,order,command等。如:Iinsistthatshe(should)doherworkalone.(3)主语是suggestion,proposal,request,decision等表示建议、请求、要求、决定等意思的词时,表语从句中谓语动词要用虚拟语气(should)+do。如:Hissuggestionisthatwe(should)holdanothermeetingtodiscussthequestion.,54,(4)表示建议、请求、命令、要求、决定等意思的名词后面的同位语从句中谓语动词要用虚拟语气(should)+do。如:Theyreceivedordersthatthework(should)bedoneatonce.,55,名词性从句典型错误例析,56,1.AsisknowntoallthatpaperwasfirstinventedinChina.析：that引导的从句是主语从句，用it作形式主语时，应把as改为it，或者原句改为定语从句：Asisknowntoall,paperwasfirstinventedinChina.2.Allthestudentswenttoseewhatthematterwaswithher.析：应把whatthematterwas改为whatwasthematter。whatwasthematter(with)和whatwaswrong(with)作宾语从句时语序不变。3.Wedontdoubtwhetherhecandoagoodjob.析：当谓语动词是doubt时，应用whether/if引导宾语从句，而donotdoubt(=believe)和疑问句中的doubt用that引导宾语从句，应把whether改为that。,57,4.Aretheshoesthatyouboughtyesterday?析：应把that改为what。that可用于名词性从句，但在从句中只能起连接作用，不充当任何成分。此句中的what引导表语从句，并在从句中作bought的宾语，相当于thethingswhich。5.ThereasonwhyIlikethedictionaryisbecauseitisusefulformywork.析：Thereason作主语，why引导定语从句，后面的表语从句习惯用that引导，应把because改为that。,58,6.ThissurprisedusverymuchthatTomshouldhaveleftwithoutaword.析：应把this改为it。it作形式主语，引导主语从句，而真正的主语是that引导的从句。7.Thequestionisifthefilmisworthseeing.析：whether可以引导表语从句，而if不能用来引导表语从句，应把if改为whether。8.Thenewscamewhichourfootballteamwon.析：应把which改为that。同位语从句只能用that来引导，不能用which来引导。,59,9.Wheredidtheyholdtheimportantmeetingisunknowntousall.析：名词性从句要用陈述句语序，主语从句Wheredidtheyholdtheimportantmeeting应改为Wheretheyheldtheimportantmeeting。10.Ifthesportsmeetwillbehelddependsontheweather.析：应把If改为Whether。whether引导主语从句，if不能引导主语从句。11.Whoknowsthetruthwilltellyouaboutit.析：应把Who改为Whoever。whoever相当于anyonewho。,60,12.Itdependsonifhehasenoughmoney.析：介词后的宾语从句用whether引导，而不用if引导，应把if改为whether。13.Studentsdonotstudyhardisnotagoodthing.析：Students前加That。that在引导宾语从句时可以省略，但引导其他名词性从句（主语从句、表语从句、同位语从句）时不能省略。14.Theywanttomakeitcleartothepublictheydoanimportantjob.析：当用it作形式宾语时，that不能省略，应在they之前加that。,61,定语从句,专项复习,62,1.(2006)北京.第31题Women_drinkmorethantwocupsofcoffeeadayhaveagreaterchanceofhavingheartdiseasethanthose_dont.A.who;/B./;whoC.who;whoD./;/2.(2006)天津卷.第12题TheBeatles,_manyofyouareoldenoughtoremember,camefromLiverpool.A.whatB.thatC.howD.as,C,D,Step1.Lead-in,63,3.(2006)重庆卷.第34题Isawawomanrunningtowardsmeinthedark.BeforeIcouldrecognizewhoshewas,shehadrunbackinthedirection_shehadcome.A.ofwhichB.bywhichC.inwhichD.fromwhich4.(2006)湖南卷.第30题Wesawseveralnativesadvancingtowardsourparty,andoneofthemcameuptous,_wegavesomebellsandglasses.A.towhichB.towhomCwithwhomD.withwhich,D,B,64,5.(2006)江西卷.第33题-Doyouhaveanythingtosayforyourself?-Yes.Theresonepoint_wemustinsiston.A.whyB.whereC.howD./6.(2006)辽宁卷.第25题Iwastoldthattherewereabout50foreignstudents_Chineseintheschool,most_werefromGermany.A.study;ofwhomB.study;ofthemC.studying;ofthemD.studying;ofwhom,D,D,65,7.(2006)福建卷.第22题Lookout!Dontgettooclosetothehouse_roofisunderrepair.A.whoseB.whichC.ofwhichD.that8.(2006)浙江卷.第13题Iwasgiventhreebooksoncooking,thefirst_Ireallyenjoyed.A.ofthatB.ofwhichC.thatD.which,A,B,66,9.(2006)陕西卷.第8题ShewaseducatedatBeijingUniversity,_shewentontohaveheradvancedstudyabroad.A.afterthatB.fromthatC.fromwhichD.afterwhich10.(2006)江苏卷.第29题Theownerofthecinemaneededtomakealotofimprovementsandemp
