副词性从句(状语从句)02怎么辨认名词性从句主语从句在句中做------宾语从句在句中做------表语从句在句中做------同位语从句在句中-----

主语宾语表语同位语1.Thathewillcomeiscertain.2.Iknowthathewillcome.3.ThetruthisthatIhavebeenthere.

4.Thefactthatshewaslatesurprisedus.主语从句宾语从句表语从句同位语从句Itiscertainthathewillcome.看从句出现的位置和充当的成分主语从句同位语和定语从句的辨析Doyouknowthefactthathestolethecar?Doyouknowthefactthattheyweretalkingabout?注意：1.如果是定语从句，它的从句肯定是不完整的，关系词肯定在句中充当成分的；而同位语从句中的that只起连接作用。

2.定语从句是对先行词起修饰作用，而同位语从句则解释说明先行词的具体内容。(同从)(定从)请判断出下列的句子属于哪种从句WhatIwanttodoistakingabath.Thenewsthattheywonthegamespreadthewholeschool.Idon’tthinkheisanhonestboy.Thefactisthathestolethecar.Doyouknowthefactthathestolethecar?Doyouknowthemanwhoisstandingoverthere?Itissaidthattheywonthegame.(主从)(同位语从句)(宾从)(表从)(同位语从句)(定从)(主从)03单击此处添加副标题内容引导词的分类名词性从句的引导词既可以有含义，又可以在句子当中充当成分。eg.WhoIrespectmostismymathteacher.ThepersonwhoIrespectmostismymathteacher.引导词包括

that，if/whether，who，whom，whose，what,which,when,where,why,how,whoever,whomever,whatever,whichever注意：

名词性从句的引导词和定从，状从引导词有很多相同的，所以要求大家首先学会区分不同类型的从句。……的人

宾语1、Thatwewillrealizeourdreamsinthefutureiscertain.2、ThefactisthatBeijingwillhold29thOlympicGamesthisyear.3、Iknowthatwellbegunishalfdone.4、HeheardthenewsthatLiuxiangsetanewworldrecord.“that”---无词义、不作成分、起连接作用（主语从句）（表语从句）（宾语从句）（同位语从句）引导词that的几点注意：1.主语从句的that放在句首看着很别扭，但必须有2.it做形式主语的句子，后方也是主语从句。Thatwewillrealizeourdreamsinthefutureiscertain.Itiscertainthatwewillrealizeourdreamsinthefuture.3.表语从句的that不可以省略。

作文总爱犯这样的错

eg.ThereasonwhyIrespecthimmostisheworksveryhard.4.宾语从句that可有可无，改错中不要专门去添加that

eg.Iknowheworksveryhard5.同位语从句的引导词

理论上都可以用，但实际使用中还是以that为主1、Whethershewillcomebackontimedependsonweather.2、Theproblemiswhetheryoucouldgiveussomevaluableadvice.3、Iaskedhimwhether/ifhecoulddomeafavor.4、CouldyoutellmethequestionwhetherEnglishisusefulforusnow.“if/whether”---“是否”、不作成分、起连接作用（主语从句）（表语从句）（宾语从句）（同位语从句）if只能引导两种名词性从句：宾语从句(介词后方的宾从不行）、不放于句首的主语从句。eg.We’reworriedaboutwhetherheissafe.2.whether四种从句均可以引导。3.whetherornot连在一起可以，但if不可以。而“whether…ornot=if…ornot”If与whether的区别：eg.Idon’tknowwhether/ifheiswellornot.Idon’tknowwhetherornotheiswell.1.Whowillgotothecollegeisstilluncertain.2.Theproblemiswhowecanfindtoreplaceher.3.Iknowwhoyouare.who,译为“谁”，在名词性从句中

作宾I

don'tknowwhosebookitis.whose译为“谁的”，在名词性从句中

作

定语what译为“1.什么2.的sth.”，在名词性从句中

作状语Whenthemeetingwillbeginisn’tdecidednow.WhereIcouldbuythebookisuncertainnow.Whatsurprisedmewaswhytheyfailedagain.Howthethiefstolethebikeisstillamystery.主语从句特殊性主语从句的that放在句首看着很别扭，但必须有it做形式主语的句子，后方也是主语从句。Thatwewillrealizeourdreamsinthefutureiscertain.Itiscertainthatwewillrealizeourdreamsinthefuture.3.单个句子作主语，谓语用单数。

Thathewillsucceediscertain.表语从句特殊性表语从句不是只能跟在be动词后方，还有look,appear,seem,remain表从引导词除了常规的词以外，还有as,asif=asthough,becauseHewaslatethismorning.Thatwasbecausehewascaughtinatrafficjam.Allthiswasovertwentyyearsago,butit’sasifitwasonlyyesterday.Helookedjustashehadlookedtenyearsbefore.宾语从句特殊性介词后方的宾语从句一般不用that，如果用，则不可以省略thatSheisnotsatisfiedwithwhatshehasachieved.Maryalwaysthinksofhowshecandomorefortheclass.Hewrotealetterofthankstowhohelpedhim.(任何一个)2.it作形式宾语时，真正的宾语从句不可以省略thatWethinkitourdutythatweshouldhelpothers.3.be+adj.这一结构后方的句子也叫宾语从句

I’mafraid(that)I’llbelate.

Weweresurprisedthathelostthegame.同位语从句特殊性同位语从句和被解释说明的名词有隔裂现象HegotthenewsfromMarythatthesportsmeetingwasputoff.WordcamethatNapoleonwouldcomeandinspecthisgrandarmy.04单击此处添加副标题内容做题思路名词性从句做题思路1.找到从句部分，判断是什么从句2.确定是名词性从句后，判断从句是否缺成分。3.如果不缺成分，根据翻译考虑that，if/whether,when/where/why/how4.如果缺成分，根据翻译考虑what(ever)，

由于名词性从句引导词与定语从句，状语从句引导词重复的较多，容易形成混杂，因此同学们需要注意训练区分各类从句判断以下句子是什么从句Sheisthegirlthattalkedtoyouyesterday.ThebookwhichIboughtlastweekwaslost.Thefactisthathestolethecar.MrLiuisthepersonwhomyoutalkedaboutonthebus.I'lltellyouwhenIcomebacksoyoucanpickmeupontime.Hewasalwaystryingoutnewideaswhenhewasachild.Youshouldhaveputthebookwhereyoufoundit.定从定从同位语从定从名词性从句状从状从05单击此处添加副标题内容配套练习1.____LiBai,agreatChinesepoet,wasbornisknowntothepublic,butsomewon’tacceptit.
