2023届高三英语总复习（人教版2019）名词性从句考点运用在复合句中起名词作用的从句叫做名词性从句。名词可以充当句子的主语、宾语、表语和同位语，因此，名词性从句包括主语从句，宾语从句，表语从句和同位语从句。①Whatwasmostimportanttoherwasherfamily.(主语从句)②Idon’tknowwhatyouwanttosay.(宾语从句)③Thegoodnewsisthatwehavewonthegame.(表语从句)④Thenewsthatwehavewonthegameistrue.(同位语从句)引导名词性从句的关联词：从属连词that,because疑问代词who,whom,whose,which,what,whether,if疑问副词when,where,why,how,缩合连接词whatever,whoever,whomever,whichever,however,whenever,wherever关联短语asif,asthough注意：连词that在引导名词性从句时无词义，不充当句子成分，只起连接作用，在主语从句、表语从句和同位语从句中不能省略，在引导宾语从句时，口语或非正式的文体中常被省去；疑问代词、疑问副词、缩合连接词以及关联短语在句中既保留自己的含义又起连接作用，在从句中充当成分。名词性从句一般都用陈述句的语序，即使从句表达的是疑问含义。例如：①Theproblemiswhathehasdonetothelittleboy.②Wealldon’tknowwhenhewillcome.一、明备考方向语法填空常考点短文改错常考点写作常用句式1.连接代词what,who(m)，whoever,which,whose等的用法；2.连接副词when,where,why和how等的用法；3.连接词that,1.连接词that与连接副词的混用；2.连接词that与连接代词的混用；3.连接词that的缺失；4.连接代词what,which,who等之间的混用；1.It＋be＋名词/形容词/动词的过去分词＋that从句2.Itlooks/seemsasif...“好像……；仿佛……”3.Thisisbecause...“这是因为……(强调原因)”4.Thereasonwhy...isthat...“……的原因是……”5.Thatiswhy...“那就是……的原因(强调结果)”6.Thequestion/problemiswhether/when/where...“问题是……”
1whether和if的用法。5.连接代词与连接副词的混用。7.Hisdream/suggestion/aim/purposeisthat...“他的梦想/建议/目标/目的是……”8.What从句＋be＋that从句1.主语从句在复合句中作主语的句子叫主语从句主语从句通常由从属连词that，whether和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。例如：①Thathestoleabikewastrue.②Whathewantstotellusisnotclear.③Whowillwinthematchisstillunknown.④WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.⑤Whetherhecanpasstheexamdependsonwhetherhestudyhardornot.⑥Whateveryoudoisnoneofmybusiness.⑦Whoevercomestoourlibrarywillbewelcome.单个的主语从句作主语时，谓语动词用单数形式。如果是两个或两个以上的主语从句作主语，谓语动词则用复数形式。例如：①Whereandwhenhewasbornhasnotbeenfound.②Whenthepersonwasmurderedandwhyhewasmurderedarestillunknown.主语从句比较长的时候，为避免句子头重脚轻，常用it代替主语从句作形式主语放于句首，而把主语从句置于句末。主句的谓语动词一般用单数形式。常用句型如下：（1）It+be+名词+主语从句。例如：①Itisafactthathehasgoneabroad.②Itisapitythatyoumissedthesportsmeetinglastweek.（2）It+be+形容词+主语从句。例如：①Itisobviousthathetoldalie.②Itiscertainthathewillwinthegame.（3）It+be+过去分词+主语从句。例如：①Itissaidthatshewillcometothepartytomorrow.②Ithasnotbeenannouncedwhentheplanearetotakeoff.（4）It+不及物动词+主语从句。例如：①Ithappenedthatthemeetingwascanceledthatday.②ItoccurredtomethatIhadforgottentobringmywallet.注意:在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气(should)+do，常用的句型是：Itisnecessary/important/natural/strange/essential,etc.)that…例如：
2①It’snecessarythatyoushouldstudyhard.②Itisstrangethatheshouldsaythat.③Itisessentialthatacollegestudentshouldmasteratleastaforeignlanguage.2.宾语从句在复合句中作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。例如：①Iwanttoknowwhathehastoldyou.②Shealwaysthinksofhowshecanworkwell.③Shewillgivewhoeverneedshelpawarmsupport.1).由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去。但如从句是并列句时,第二个分句前的that不可省。例如：Hehastoldme(that)hewillleaveWuhanandthathewillgotoShanghaitomorrow.注意:在insist,suggest,advise,decide,demand,desire,require,request,order,command等表示“坚持、建议、决定、要求、命令”（“坚决要命”）等意义的动词后，宾语从句中谓语部分常用虚拟语气，即should+动词原形。例如：①Iinsistthatshe(should)doherworkalone.②Thecommanderorderedthattroops(should)setoffatonce.但是,如果suggest作“表明、暗示”讲,insist作“坚持说、坚持认为”讲，则其后的宾语从句中用陈述语气。例如：①Thesmileonhisfacesuggestedthathehadpassedtheexamination.②Theboyinsistedthathehadnotstolenthemoney.2).用whether或if引导的宾语从句whether和if均可引导动词后的宾语从句，常可互换。但从句中有ornot时或介词后的宾语从句中只能用whether连接。其它名词性从句，如主语从句、表语从句、同位语从句中表示“是否”只用whether.介词后的宾语从句一般不用which和if引导，要用whether和what。that也很少引导介词宾语从句，只在except,but,besides等之后才用。例如：①Idon’tcareaboutwhetheryouhavemoneyornot.②Everythingdependsonwhetherwehaveenoughmoney.③Heseldomloseshistemperexceptthatyoumakeafoolofhim.3).宾语从句中的时态呼应宾语从句的谓语动词时态受主句谓语动词的影响，如果主句的谓语动词是一般现在时，从句中的谓语动词可以用各种时态。例如：①IknowthathestudiesEnglisheveryday.②IknowthathestudiedEnglishlastterm.③Iknow(that)hewillstudyEnglishnextyear.
3④WeallknowthathehasstudiedEnglishsince1998.如果主句中的谓语动词用了一般过去时，则从句中的语动只能用过去时的某种形式，如一般过去时，过去进行时，过去将来时等。例如：①Webelievedthathehadearnedenoughmoneytobuildahouse.②TheteachertoldusthatTomhadleftusforAmerica．当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：Theteachertoldusthatthesunrisesintheeast.4).当主句是I/Wethink(suppose,expect,believe,guess,imagine)时，其后的宾语从句如果是否定形式，常把否定词not从从句中转移到主句中成为否定的转移。例如：①Wedon’tbelievethathewillwinthegame.②Idon’tthinkhewilldoso.注意：doubt用于肯定结构时，后面用whether/if引导名词性从句；用于否定结构或疑问结构时，后面用that引导名词性从句。besure用于肯定句或疑问句时，后接that引导的名词性从句；用于否定句时，后接whether/if引导的名词性从句。例如：①Idoubtwhetherhewillcometomorrow.②Thereisnodoubtthathewillcometomorrow.③Iamsurethathewillwinthegame.④Iamnotsurewhetherhewillwinthegame.3.表语从句在复合句中作表语的句子叫表语从句。表语从句常放在系动词之后。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用asif,because引导。其基本结构为：主语+系动词+表语从句。例如：①Thefactisthatwehavelostthegame.②That’sjustwhatIwant.③Thisiswhereourproblemlies.④Thatiswhyhedidn’tcometothemeeting.⑤Itlooksasifitisgoingtorain.⑥Thisisbecausehemissedthetrainbyoneminute.注意：当主语是reason时，表语从句要用that引导而不是because。例如：Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning.4.同位语从句在复合句中作同位语的从句叫同位语从句。同位语从句用于解释说明其前面的名词的具体内容。同位语从句一般跟在某些表示抽象概念的名词后,如news,idea,information,fact,hope,thought,belief等，用来说明名词所表示的具体内容，引导同位语从句的连接词通常有that,whether和连接副词when,where,why,how；连接代词who，what，whose，which也可以引导同位语从句。例如：①Thenewsthathewonthefirstplacewastrue.②Itisaquestionhowhedidit.
4③Theproblemwhetherweshouldcontinuetodotheexperimenthasbeensolved.④Wehaven’tsettledthequestionwherewearegoingtospendoursummervacation.⑤Ihavenoideawhenshewillbeback.⑥Thequestionwhoshoulddotheworkrequiresconsideration.同位语从句一般紧跟在被解释的名词之后，但有时候也可以分开，将从句放在句末。例如：①Thesuggestioncamefromthechairmanthatthenewruleshouldbeadopted.②WordcamethatMr.Presidentwouldcomeandinspectourschool.5.同位语从句与定语从句的区别（1）定语从句修饰限定先行词，它与先行词是修饰关系；同位语从句解释说明先行词的具体内容，它与先行词是同位关系。①The plane that has just taken off is for Paris. （定语从句） ②The fact that he has died is quite clear. （同位语从句）（2）定语从句由关系代词或关系副词引导，关系词在从句中担当相应的句子成分，关系代词在从句中作宾语时经常可省略。同位语从句主要由连词that 引导，在从句中不充当句子成分；where, when, how, who, whether, what 等连词也可以引导同位语从句，这些连词则在从句中担当成分。①The news that he told me is true. （定语从句）②The news that he has just died is true. （同位语从句）③The problem that we’re facing now is how we can collect so much money. (定语从句)④The problem how we can collect so much money is hardto solve. （同位语从句）⑤The question that he raised puzzled all of us. （定语从句）⑥The question whetherheissuretowinthegameishardtoanswer.（同位语从句） （3）同位语从句与先行词一般可以用be动词发展成一个完整的句子, 而定语从句则不能。如：①Theideathatwecanasktheteacherforadviceiswonderful.（同位语从句）→The idea is that we can ask the teacher for advice.②The fact that the earth moves around the sun is known to all. （同位语从句）→The fact is that the earth moves around the sun.③Pay attention to the problem how we can protect the wild animals. （同位语从句） →The problem is how we can protect the wild animals.1.Wenowrealize________importantfamilyisandhowimportanttobenearthem,especiallywhenyou’reraisingchildren.2.Membersleavebooksonparkbenchesandbuses,intrainstationsandcoffeeshops.________findstheirbookwillgotothesiteandrecordwheretheyfoundit.3.Thejourneywasintendedtoachievemorethan________CaptainRobertFalconScotthaddone.4.Themostpleasantthingoftherainyseasonis________onecanbeentirelydust.5.Scientistsarestillnotexactlysure________genesinfluenceaging,buttheybelievethattheydo.6.Itisoftenthecase________anythingispossibleforthosewhohangontohope.7.Youhavetoknow________you'regoingifyouaretoplanthebestwayofgettingthere.8.Itrulybelieve________beautycomesfromwithin.

6Whetherthereislifeonthemoonisaninterestingquestion.月球上有没有生命是个有趣的问题。Ihavenoideawhenhewillcomebackhome.我不知道他什么时候回到家。ThethoughtcametohimthatMaryhadprobablyfallenill.他想到玛丽可能生病了。(二)连接代词who/whom,what,which与whoever/whomever,whatever,whichever的用法和区别在这两类连接词中，前面三个连接词在引导名词性从句时依然带有疑问的语气和含义，分别表示“谁”“什么”和“哪一个”。后面三个连接词则表示“无论……”的含义，并带有具体的针对性，不带疑问的语气和含义。Theproblemiswhowecangettoreplaceher.问题是我们找谁去替代她。Whoeverdiditshouldbepunished.无论是谁干的都应当受到惩罚。(三)虚拟语气在名词性从句中的使用一般来说，在某些特定动词后的宾语从句中，谓语动词用“should＋动词原形”，should可省略。常见的这类动词有“一个坚持”(insist)；“两个命令”(order,command)；“三个建议”(suggest,advise,recommend)；“四个要求”(desire,require,demand,request)；“外加一个敦促”(urge)。Iinsistthatshe(should)doherworkalone.我坚持她应当单独做她的工作。Thecommanderorderedthattroops(should)setoffatonce.司令员命令部队马上出发。(四)同位语从句与定语从句的区别同位语从句的作用相当于名词，用来解释说明前面名词(短语)的内容，常见的名词(通常是抽象名词)有idea,thought,fact,evidence,belief,doubt,fear,hope,proposal,truth,news,possibility等；定语从句的作用相当于形容词，充当定语用来修饰主句中的某个名词或代词。Thenewsthatourfootballteamwonthematchwastrue.(同位语从句)我们足球队赢了那场比赛的消息是真的。Thenews(that)weheardontheradiowastrue.(定语从句)我们在收音机里听到的那则消息是真的。三、练高频题点Ⅰ.语法填空题点全练1．I'mnotsureismorefrightened,meorthefemalegorilla(大猩猩)thatsuddenlyappearsoutofnowhere.2．Thisismyfatherhastaughtme—toalwaysfacedifficultiesandhopeforthebest.3．Thegoldmedalwillbeawardedtowinsthefirstplaceinthebicyclerace.4．Earthquakesworrypeoplealot.Thereasonisweoftendonotknowwhentheyarecoming.5．Successpartiallydependsonyouhavethepatiencetodosimplethingsperfectly.6．Fromspace,theearthlooksblue.Thisisabout71%ofitssurfaceiscoveredbywater.

9语篇解读：本文讲述了两位异国的老太太，虽然语言不通，但是在现代技术的帮助下互相交流，彼此关心，让人再次想起“远亲不如近邻”这句古语。1．is 【解析】考查动词时态。表示方位的介词短语位于句首，谓语动词是be,stand,sit,lie等时，用完全倒装形式。本句真正的主语apaperbag是第三人称单数，全文的基本时态是一般现在时，故填is。2．the 【解析】考查冠词。根据后面的“nextdoor”可知，此处应特指隔壁的那所房子，故填定冠词the。3．obviously 【解析】考查副词。设空处修饰动词told，要用副词，故填obviously。4．tosupply 【解析】考查非谓语动词。decide后跟动词不定式作宾语，意为“决定做某事”，故填tosupply。5．container 【解析】考查名词。句意：我知道纸袋里面是什么——一瓶热汤和一个装有米饭、蔬菜和肉的容器。冠词后面应填名词，根据句意可知，设空处指“盛饭菜的容器”，故填container。6．between 【解析】考查介词。根据设空后的内容可知，此处指作者和老太太之间的交流，两者之间应用介词between。7．which 【解析】考查定语从句。分析句子结构可知，空处引导非限制性定语从句，先行词是表示物的thescreen，而且在从句中作主语，故填关系代词which。8．if/whether 【解析】考查宾语从句。分析句子结构可知，空处引导宾语从句作know的宾语，根据语境可知，该空表示“是否”之意，故填if/whether。9．us 【解析】考查代词。介词of后面要用代词的宾格作宾语，故填us。10．ringing 【解析】考查非谓语动词。keep后面用动名词作宾语，意为“一直做某事”。故填ringing。
