示人或事物的名称的词叫名词。2.名词的句法作用：名词在句中主要作主语、宾语、表语和同位语。另外还可以作定语、状语。3.名词性从句：在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语，由一个句子来充当，这个句子就叫名词性从句。4.名词性从句的种类：根据名词性从句在句子中所充当的不同成分，名词性从句可以分为主语从句、宾语从句、表语从句和同位语从句。.二.主语从句1.主语从句的连接词1).连接词:that,whether(1).Thathewillwiniscertain.(2).IthasbeenreportedthatsalesofbeefinChinawillincrease.(3).Whetherweshallraiseducksorgeeseremainstobedecided.(4).Whetherhe’lljoinusinthediscussionisofgreatimportance..2).连接代词:who,whom,whose,what,which,whoever,whatever,whichever(1).Itisclearwhoisafraidofhavingachangeinlandownership.(2).Whosebagitiscannotbetold.(3).WhatIndianeedsisalawtomakelandownershipfairer.(4).Itisnotyetdecidedwhichcashcrop（经济作物）willbeproducednextyear.(5).Whateverhesaidwasright.(6).Whoevergotheremustgetreadyby6o’clock..3).连接副词:when,where,why,how,howmany,howmuch,howlong,howsoon,howoften例:(1).Whenwe’llstarttomorrowwillbetoldsoon.(2).Wherewecanbuyoxenissomethingweneedtofindout.(3).Whyhecamehereisnotknown.(4).Howwecanprotectthegrainfromdampneedstobediscussed.(5).Howmanypeoplediedfromstarvationthatyearwillneverbeknown.(6).Howoftenhe’llgotoseehisgrandmotherdependsonthetimehecanspare..2.注意点1).主语从句一律用陈述句语序,即主语在前,谓语在后.例:正:Whenhewillcomeisnotknown.误:Whenwillhecomeisnotknown.2).连接词that在从句中无实际意义,但不能省略.例:正:Thathewillnotcometothemeetingthiseveningistrue.误:Hewillnotcometothemeetingthiseveningistrue..4).whoever,whatever,whichever等词可以引导主语从句,但nomatterwho,nomatterwhat等不能.5).为避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.Itiswellknown/reported/thought/said/…that…Itisclear/necessary/certain/doubtful/…that…Itisapity/ashame/anhonour/…that…Itdoesn’tmatterwhether…/Itseemsthat…Ithappensthat….it作形式主语和it引导强调句的比较It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。例如：Itisapitythatyoudidn’tgotoseethefilm.Itdoesn’tinterestmewhetheryousucceedornot.Itisinthemorningthatthemurdertookplace.ItisJohnthatbrokethewindow..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….主语从句不可位于句首的五种情况：（1）if引导的主语从句不可居于复合句句首。（2）Itissaid/reported…结构中的主语从句不可提前。例如：ItissaidthatPresidentJiangwillvisitourschoolnextweek.ThatPresidentJiangwillvisitourschoolnextweekissaid.（3）Ithappens/occurs…结构中的主语从句不可提前。例如：Itoccurredtohimthathefailedintheexamination.Thathefailedintheexaminationoccurredtohim.√×√×.（4）Itdoesn’tmatterhow/whether…结构中的主语从句不可提前。例如：Itdoesn’tmatterwhetherheiswrongornot.Whetherheiswrongornotdoesn’tmatter.（5）含主语从句的复合句是疑问句时，主语从句不可提前。例如：Isitlikelythatitwillrainintheevening?Isthatwillrainintheeveninglikely?√×√×主语从句不可位于句首的五种情况：.三.宾语从句1.宾语从句的引导词:宾语从句的连接词与引导主语从句的连接词相同.2.注意点1).宾语从句一律用陈述句的语序.2).引导宾语从句的连词that也无实际意义,多数情况下可以省略.3).whether和if都可以引导宾语从句但:(1).当whether后紧跟ornot时,不用if.例:Idon’tknowwhetherIwillstayornot.(2).介词后面的宾语从句不能用if.例:IworryaboutwhetherIhurtherfeeling..4).that在宾语从句中的省略与保留(1).在主+谓+it(形式宾语)+宾补+that从句(真正宾语)的句型中不省略.例:Wemustmakeitclearthatwemeanwhatwesay.(2).由连词and连接的两个由that引导的宾语从句中,that不省略.例:Hetoldmethathewouldcomeandthathewouldcomeontime.宾语从句.1.作动词的宾语(1)由that引导的宾语从句(that通常可以省略),Iheardthatbejoinedthearmy.(2)由what,whether(if)引导的宾语从句，例如：Shedidnotknowwhathadhappened.Iwonderwhetheryoucanchangethisnoteforme.(3)动词＋间接宾语＋宾语从句。例如：Shetoldmethatshewouldacceptmyinvitation.2.作介词的宾语，Oursuccessdependsuponhowwellwecancooperatewithoneanother..3.作形容词的宾语Iamafraid(that)I’vemadeamistake.注意：that引导的从句常跟在下列形容词后作宾语：anxious,aware,certain,confident,convinced,determined,glad,proud,surprised,worried,sorry,thankful,ashamed,disappointed,annoyed,pleased,hurt,satisfied,content等。也可以将此类词后的that从句的看作原因状语从句。4.it可以作为形式宾语it不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that从句则放在句尾，特别是在带复合宾语的句子中。Wehearditthatshewouldgetmarriednextmonth..5.否定的转移若主句谓语动词为think,consider,suppose,believe,expect,fancy（想象）,guess,imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。Idon’tthinkthisdressfitsyouwell.我认为这件衣服不适合你穿。.四.表语从句1.表语从句的引导词:基本上与主语从句的引导词相同.连词除了that,whether(不用if)外,还可以用because.在连系动词seem,look之后还可用asthough(asif).例:(1).Thatishowmiceruinmanystoresofgraineveryyear.(2).Thequestionwaswhenthebutcherwaslikelytocomebackfromthetown.(3).ThefactremainsthatachangeinlandownershipisneededinIndia.(4).Thatiswhathetoldus.(5).Itseemsasifitisgoingtorain..2.注意点1).表语从句一律用陈述句的语序.2).表语从句的引导词that无实际意义,但不能省略.3).表语从句只能用whether,而不能用if引导.4).特别注意：Thereason…isthat…或This/it/that/isbecause…等句型.例如:今天早上他迟到的原因是因为路上行人太多.正:Thereasonwhyhewaslatethismorningisthattherewasalotoftrafficontheroad.或:Hewaslatethismorning.Thatwasbecausetherewasalotoftrafficontheroad.或Therewasalotoftrafficontheroad.Thatwaswhyhewaslatethismorning..五.同位语从句1.同位语从句的引导词:that2.同位语从句和定语从句的区别:如果that作从句中的某一成分,则是定语从句,如果that不作从句中的任何成分,则是同位语从句.例:(1).Ihadnoideathatitwassolate.(主系表结构,that不作从句中的成分,同位语从句)(2).Istillremembertheplacethatwevisitedlastyear.(主谓宾结构,that作从句中的宾语,定语从句)3.that引导的同位语从句前面的名词常见的有:idea,fact,news,belief,thought,doubt,suggestion,proof,message,order,conclusion,desire,theory,truth,word等..同位语从句与定语从句的区别(1)定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。(2)定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：ThenewsthathetoldmeisthatTomwouldgoabroadnextyear.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）2)ThenewsthatTomwouldgoabroadistoldbyhim.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）.名词性从句几乎每年高考都要考,在各种
