名词性从句认得出做得对用得好1、Understandthedefinitionandclassificationofnounclauses;2、Knowhowtochoosetheconjunctionofnounclauses;3、Mastertheuseofnounclausesinwriting.Learningaims:一、认得出：按所处位置辨认四类名词性从句1.定义：在复合句中起名词作用的从句2.类别：主语从句、宾语从句、表语从句和同位语从句。如何识别名词性从句？【要点1】在谓语动词is之前；引导词when在从句中

作时间状语。从句作主语时谓语动词一般

用单数。1.

Exactlywhenthepotatowas

introducedinto

Europe

isuncertain,butitwasprobablyaround

1565.主语从句【要点2】在谓语动词excites之前；从句结构及意义均完整，故需要“无成分，无意义的”引导词

that。that引导主语、表语、同位语从句时一般不可省。2.ThatwewillhaveapicnicnextSunday

excites

usallthesedays.

Itisknowntousallthattheearthgoesaroundthesun.【要点3】本句中It作形式主语，替代后面真正主语从句3.Thattheearthgoesaroundthesunisknowntous.平衡常用it作形式主语的基本句式（1）It+be+

名词

（nowonder,anhonor,agoodthing,apity,nosurprise）+that从句；（2）It+be+

形容词（obvious,surprising,good,wonderful,funny,possible,likely,certain,probable）

+that从句；（3）It+be+

动词的过去分词

（said,reported,thought,expected,decided,announced,arranged，knowntoall）+that从句；（4）It+

不及物动词(happens,appears,occurstosb

）+that

whenhewillcome.Shealwaysthinksofhowshecanworkwell.2.主语+谓语+介词+宾语从句3.主语+系动词+形容词

+宾语从句IamsorrythatIlostyourbook.宾语从句Iamglad

thatyouaresatisfiedwithyourjob.

【要点】be+glad/certain/sure/afraid/pleased...等后可以接宾语，称之为“be+形容词”搭配。宾语从句连接词选择4要点：

1.如果宾语从句是个陈述句，就用连词that引导；2.如果宾语从句是由特殊疑问句变来的，该从句可以用由原来引导特殊疑问句的疑问代词或疑问副词变来的连接代词或连接副词引导；3.如宾语从句表示不肯定或疑问，如"是否"、"是不是"、"能否"等，就用连词if/whether来引导；4.有的宾语从句表示"某人在某地、某时""做的事"、"说的话"、"想到的"、"记得的"等意思，就要用关系代词what来引导该从句，what本身既是引导词，又是从句中宾语。宾语从句中常常后跟“should+动词原形”（should可省略）的动词：1个“坚持”（insist）；2个“命令”（order,command）；3个“建议”（suggest,advise,recommend）；4个“要求”（demand,desire,request,ask）单句语法填空1．Whenwearrivedat________peoplecallBirdParadise,weweredelightedtofindthousandsofbirdssettingthere.2．Ifyoufollow________ismentionedabove,youwillbeacceptedbypeoplearoundyou.3．Youcanvisitalocalchocolatefactorytolearn________chocolateismadeandmanufactured.whatwhathow作“是否”的意思讲时，在下列情况下一般只能用whether，不用if：1.

引导主语从句并在句首时；2.

引导表语从句时；3.

引导从句作介词宾语时；

4.

连词后紧接“ornot”时，但若分开时也可以用if；5.

后接动词不定式时。if和

Thatshewillwinthematchiscertain.3.that引导宾从后置，用形式宾语it代替时不能省；Chinahasmadeitcleartotheworldthatitisstronglyagainstterrorism.4.名词性从句本身为复合句且复合句在主句前时，that不能省略。Hesaid

（keep,

ThenewsthatourWomenVolleyballTeamhaswonthegameisexciting.2.

WordcamethatourWomenVolleyballTeamhaswonthegame.【简析】这两句均为同位语从句，特征是说明其前面名词的具体内容。其中第二句出现了“分割现象”——名词和同位语从句被谓语动词等分割开来。同位语从句通常由that引导，也可根据需要用到其他一些连接词。同位语从句

advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word…【知识拓展七】常见的同位语从句前的抽象名词

同位语从句和定语从句的区别：

that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；

that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。

试比较下面两个例句:

1.Ihadnoideathatyouwerehere．

（

that

引导同位语从句，不能省略）

2.Haveyougottheidea（that）thisbookgives

接

词：that,whether,if（不充当从句的任何成分）连接代词：what,whatever,who,whoever,whom,

whose,which连接副词：when,where,how,why所谓“缺什么补什么”是指句型结构与连词之间的关系。①如果从句中缺主语，指人用who，指物用what；缺宾语，指人用whom，指物用what；②缺时间状语用when；地点状语用where；原因状语用why；方式状语用how；③缺定语用what或which；④什么都不缺用that。2.抓住两个要点“语法功能”（从句中所缺成分）“词义辨析”（连词的意义）Whichever，whatever引导两种从句的区别一、whichever引导的两类从句1.引导名词性从句，用于引导名词性从句，相当于any…that，其意为“无论哪个”“随便哪个”。如：Youcanpickwhicheveroneyoulike.你喜欢哪个就挑哪个。2.引导让步状语从句，用于引导让步状语从句时，相当于nomatterwhich，其意为“无论哪个”“不管哪个”。如：Whicheveryouchoose,theotherswillbeangrywithyou.无论你选哪个，其余的人都会生气的。二、whatever引导的两类从句1.引导名词性从句，用于引导名词性从句（主要是引导主语从句和宾语从句），其意相当于anythingthat或everythingthat。如：Whatevershedidwasright.她做的一切都是对的。Hedoeswhateversheaskshimtodo.她要他做什么，他就做什么。Iwilljustsaywhatevercomesintomymind.我想到什么就说什么。2.引导让步状语从句，用于引导让步状语从句，其意相当于nomatterwhat。如：Whateverhappens,don’tforgettowrite.无论怎样别忘了写信。Whateveryousay,Iwon’tbelieveyou.不管你说什么，我决不相信你的话。
