第2页第2页主语从句惯用it作形式主语放句首因而我们常见到这种句式：It+be+n./adj./-ed从句（that,whether,etc.)例：It'sapitythatyoushouldhavetoleave.=Thatyoushouldhavetoleaveisapity.ItisgreatthatIhaveateacherlikeyou.=ThatIhaveateacherlikeyouisgreat.第3页第3页

Ⅲ.主语从句连接词一、主语从句连词that(无词义,不作成份,不能省略);whether(是否),if不能位于句首。Thathewillcomeandhelpusiscertain.Whetherwewillsucceedisstillaquestion.Itisnotknownifhewillcome.注意:已拟定事由that引导;没决定事由whether引导.

第4页第4页3.连接副词when,where，why,how,howlong,howoften,howsoon,howfar,howmany/much等.Whenthetestwillbegivenisnotyetdecided.Howmuchwecanspendmustbeagreedon.2.连接代词what,whatever,who,whoever,whose,which,whichever等.Whatheishasnothingtodowithyou.Whoseticketthisishasnotbeenfoundout.第5页第5页特殊句式1.Ihate____

D．for第6页第6页第7页第7页同位语从句在一个更长句子中作同位语使用句子叫同位语从句。同位语与其前词或短语表示是同一事物。如：Thefact

thatsheisillshouldbeconsidered.第8页第8页Thenews

thatourteamhaswonthematch

istrue.Hisdelayisdueto

thefactthatthecarwentwronghalfway.同位语从句同位语从句普通跟在名词fact,news,promise,truth,belief,thought,idea,answer,information,doubt,knowledge,hope,law,opinion,plan,suggestion后面,用以阐明或解释前面名词.第9页第9页TheDifferencesBetweenAppositiveclausesandAttributiveClauses

如何区别同位语从句与定语从句第10页第10页同位语从句与定语从句不同之处1、从句作用不同：同位语从句用来深入说明前面名词内容；定语从句用来修饰、限定前面名词。e.g.Thenewsthatourteamhaswonthefinalmatchisencouraging.（从句阐明“消息”内容：我们队取得了决赛胜利。）Thenewsthatyoutoldusisreally

encouraging.（从句对“消息”加以限定：是你告诉我们，而非来自其它渠道。但消息是何内容却不得而知。）第11页第11页2、引导从句关联词that功效不同：that引导同位语从句时是一个纯连词，不充当任何成份；而引导定语从句that是关系代词，既指代先行词又须在从句中充当成份。e.g.1)DadmadeapromisethathewouldbuymeCDplayerifIpassedtheEnglishtest.（that不充当任何成份）2)Dadmadeapromisethatexcitedallhischildren.（that指代promise，又在从句中充当主语。）第12页第12页高一英语语法同时辅导3、that引导同位语从句时是一个纯连词，故不能用which替换；而that引导定语从句时是代词，常能够和另一关系代词which替换。e.g.ThefactthatheisfromCanadaisnewtome.（that不可换为which）ThefactthatsurprisedmeisthatheisnotChinese.（第一个that可换为which，第二个不行，由于它引导是表语从句。）第13页第13页4、引导同位语从句关联词，除that外，还可以依据句义使用任何其它疑问代词或副词；而定语从句不可用what,how,whether等引导。e.g.IhadnoideaatallwhatIshoulddonext.

Thereisnoproofwhetherhewaskilledbyothers.第14页第14页同位语从句定语从句引导词that只起连接作用不充当句子成份引导词that除了引导句子外还充当一定句子成份同位语从句与前面名词是同位关系表示这个名词内容定语从句对先行词起修饰作用，表示“…”。同位语从句that普通不能省而定语从句中关系代词that，当其在从句中做宾语时，常省略一.同位语从句PK定语从句第15页第15页PracticeI.Tellthefunctionoftheclausesinthefollowingsentences说出下列从句功效：A:Appositive（同位语）;B:Attributive（定语）Hisproposalthatwegothereonfootisacceptable.Manyteachersholdtheviewthatteenagersshouldnotspendtoomuchtimeonline.3.Thefirstrequestthathemadewastoaskforfreedom.4.Doyouhaveanyideawherewewillbesent?5.Isthisthecompanywhereyourfatherworks?6.Thisisthereasonthathegaveforhisabsence.7.Hemadeanexcusethathiscarbrokedownon
