re，why，how)或whether引导。Ihavenoideawhathashappenedtohim.3.有时同位语从句不紧跟在它所说明的某个名词后，而是被别的词隔开。ThestorygoesthatWilliamTelldidkillthekingwiththatsword.,书面表达中名词性从句易错点聚焦,1.语序问题(误)Thesepicturesshowyouwhatdoesourvillagelooklike.(正)Thesepicturesshowyouwhatourvillagelookslike.宾语从句的语序应用陈述语序，而不是特殊疑问句的语序。(误)Doyouthinkwhichoftheseisthemostusefulinvention?(正)Whichofthesedoyouthinkisthemostusefulinvention?在疑问句中，宾语从句的连接词应担当特殊疑问词的角色位于句首。,2.what和that的运用(误)Americawasthatwasfirstcalled“India”byColumbus.(正)Americawaswhatwasfirstcalled“India”byColumbus.在名词性从句中，连接词that既不作任何句子成分，也没有意义；而连接代词what则相反，它既充当从句的主干成分也有其自身的意义。另外，我们可以把what解释为：the名词that/which。3.whether和if的运用(误)Ifwellholdthepartyhasnotbeendecidedyet.(正)Whetherwellholdthepartyhasnotbeendecidedyet.whether适用于任何情况；if(作“是否”讲)仅限于动词宾语从句中，但discuss，decide等动词后的宾语从句除外。,4.连接词的使用易受汉语干扰(误)ThereasonwhyIwaslateisbecauseIwastrappedinthetrafficjam.(正)ThereasonwhyIwaslateisthatIwastrappedinthetrafficjam.第一句通过提取简化可得出：Thereasonisbecause.在英语中显然造成了重复现象。,PART2,重温高考真题,考向1宾语从句中的连接词,.单句语法填空1.Thegoldmedalwillbeawardedtowinsthefirstplaceinthebicyclerace.(2018天津),答案,解析,解析句意为：无论谁获得自行车比赛第一名，金牌将授予他。分析句子可知，空格处作to的宾语，同时在后面的从句中作主语，再根据句意可知，从句主语指人，且意为“无论谁”，故用whoever。,whoever,1,2,3,2.Imnotsureismorefrightened，meorthefemalegorilla(大猩猩)thatsuddenlyappearsoutofnowhere.(2018全国),答案,解析,解析句意为：我不确定谁(哪一个)更害怕，我还是突然出现的雌性大猩猩。此处为宾语从句，空格处表示“谁”或“哪一个”，故用who/which。,who/which,1,2,3,3.Asnaturalarchitects，thePuebloIndiansfiguredoutexactlythicktheadobewallsneededtobetomakethecycleworkonmostdays.(2015全国),答案,解析,解析分析句子结构可知，这是一个宾语从句。根据形容词thick及结构可知，这里的意思是印第安人算出土坯墙的确切厚度。空格后为形容词，因此空格上应用副词，故填how。,how,1,2,3,.单句改错(每小题仅有1处错误)1.MyuncleistheownerofarestaurantclosetothatIlive.(2016全国),where,答案,解析,解析由句子结构可知，介词to之后为宾语从句，而宾语从句中缺少地点状语，故用where引导。,2.Afterlookingatthetoyforsometime，heturnedaroundandfoundwherehisparentsweremissing.(2015全国)或Afterlookingatthetoyforsometime，heturnedaroundandfoundwherehisparentsweremissing.,that,答案,解析,解析句意为：他转过身发现父母不见了。由句意可知，宾语从句句意完整且不缺少成分，所以应该用that引导从句或省略。,考向2表语从句中的连接词,.单句语法填空1.Withouthissupport，wewouldntbewearenow.(2018北京),答案,解析,解析句意为：假如没有他的支持，我们就不会取得现在的成就。“wearenow”是表语从句，结合句子的意思可知，此处表面意思是指我们所处的位置，故该从句应用where引导。,where,1,2,3,4,2.Thisismyfatherhastaughtmetoalwaysfacedifficultiesandhopeforthebest.(2018北京),答案,解析,解析句意为：这就是我父亲教我的总是要直面困难，并且抱最大的希望。“myfatherhastaughtme”是表语从句，该空在从句中作teach的直接宾语，且表示“父亲教我的道理”，故该从句应用what引导。,what,1,2,3,4,3.40gramsofmeatperdayispeopleshouldconsumeinordertostayfit.(2018北京海淀区二模),答案,解析,解析句意为：为了保持健康，人们每天应该消耗40克肉。“peopleshouldconsume”是表语从句，该从句中consume缺少宾语，且表示“所需消耗的东西”，故要用what引导该从句。,what,1,2,3,4,4.Earthquakesworrypeoplealot.Thereasonisweoftendonotknowwhentheyareing.Peoplecannotprepareforit.(2017河南中原名校联考),答案,解析,解析设空处引导表语从句，从句的结构和意义完整，所以用that引导。,that,1,2,3,4,.单句改错(仅有1处错误)Ibelievehardworkisthatittakestoacplishmygoal.(2018河北石家庄二中一模),what,答案,解析,解析本句中what引导表语从句，并在句中作动词take的宾语。that引导表语从句不作句子成分。,.单句语法填空1.Everyyear，makesthemostbeautifulkitewillwinaprizeintheKiteFestival.(2017北京),答案,解析,解析句意为：每年，在风筝节上风筝做得最漂亮的人会赢得奖品。whoever无论谁，表泛指，在句中作主语，相当于anyonewho。,whoever,考向3主语从句和同位语从句中的连接词,1,2,3,4,2.Yoursupportisimportanttoourwork.youcandohelps.(2016北京),答案,解析,解析句意为：你的支持对我们的工作很重要，无论你们做什么都会有帮助。从句谓语动词do后面缺少宾语，且此处引导主语从句，故用whatever。,Whatever,1,2,3,4,3.Itisoftenthecaseanythingispossibleforthosewhohangontohope.(2016江苏),答案,解析,解析句意为：通常情况下，对于那些心存希望的人来说，一切皆有可能。本句中的it为形式主语，真正的主语为后面的名词性从句，从句结构完整，不缺成分，故要用that引导。,that,1,2,3,4,4.youcanlearnfromtheantphilosophyis:Nevergiveup，lookahead，staypositiveanddoallyoucan.(2017江西上饶模拟),答案,解析,解析分析句子结构可知，设空处引导主语从句，且从句中learn后缺少宾语，故填What。,What,1,2,3,4,.单句改错(仅有1处错误)Itsagreatpitywhatwewontbeabletofinishthetaskontime.(2017唐山模拟),that,解析It作形式主语，真正的主语为that引导的从句。,答案,解析,PART3,热考点集训,.单句语法填空1.weunderstandthingshasalottodowithwhatwefeel.2.Ashipinharborissafe，butthatsnotshipsarebuiltfor.3.IsittruethatMikerefusedanofferfromYaleUniversityyesterday?Yeah，butIhavenoideahedidit；thatsoneofhisfavoriteuniversities.4.Thepaniesareworkingtogethertocreatetheyhopewillbethebestmeansoftransportinthe21stcentury.5.Itdoesntmatteryouturnrightorleftatthecrossingbothroadsleadtothepark.,查看答案,How,what,why,what,whether,6.Asmanyasfivecoursesareprovided，andyouarefreetochoose_suitsyoubest.7.Jerrydidnotregretgivingthementbutfelthecouldhaveexpresseditdifferently.8.Thenoticecamearoundtwointheafternoonthemeetingwouldbepostponed.9.Afarmeronceorganizedapetitionbetweenhisdogandhisrabbit.Hedugaholeinoneofhisbiggestfields，andhidacarrotandaboneinit.Hewantedtoseeanimalwouldfindthemfirst.10.Itcanbereallyupsettryingtoaskforsomethinginastoreortotellthetaxidriveryouaregoing.,查看答案,whichever,that,that,which,where,.单句改错(每小题仅有1处错误)1.ThatBarbaraJonesofferstoherfansishonestyandhappiness.2.Itwasneverclearwhetherthemanhadntreportedtheaccidentsooner.3.Itisstillunderdiscussioniftheoldbusstationshouldbereplacedwithamodernhotelornot.4.Hesaidhowalovelygirlshewas.5.Thevillagershavealreadyknownwhichwelldoistorebuildthebridge.,What,why,whether,what,查看答案,what,6.Whatheshoulddoishestaysathomeandwaitsforhismotherfromwork.7.Thereasonwhyhewaslatewasbecausehisbikewentwrong.8.Idliketostartmyownbusines
