Thesubjectclause主语从句大挑战：唱歌，从8句从句中找出主语从句！看谁最先找到！

学习目标1.理解什么叫主语和主语从句。2.掌握主语从句引导词的用法和注意事项。

3.在作文中会写有关主语从句的句子。1.Theydidn’tknowmyaddress._________2.Seeingisbelieving._________3.Todomorningexercisesisgoodforyourhealthy.___________4.Itisagreathonorforustobeinvitedtotheparty.______________5.Sixplussevenisthirteen.________6.Thevillagersdidn'trealizehowseriousthepollutionwas.__________7.Whatwewilldonextisnotdecided.________

PartA先找谓语动词，并指出主语所在，说出由什么词充当。————————————————————————————————————————————代词动名词不定式形式主语(代词)数词————————名词—————————————句子概念：主语是动作的发出者，位谓语动词________,是_____词或_____词性表达，表示____\____\______之前名名人物事1Thathewillcomeiscertain.2Whetheritwillpleasethemisnoteasytosay.3Whatseemseasytosomepeopleseemsdifficulttoothers.4Whichsidewillwinisnotclear.5Whyhediditremainsamystery.找出谓语动词和引导词，并定位主语从句所在(用下划线表示)提示

：主语从句如何划全？由引导词

划到下一个谓语动词出现为止。6.Whentheywillstartisnotknownyet.7.Howhebecameagreatscientistisknowntousall.8.Whowilltakepartinthemeetinghasnotbeendecided.9.Whoeverbreaksthelawwillbepunished.10.Wheresheisfromisunknown.找出谓语动词和引导词，并定位主语从句所在(用下划线表示)归纳总结：主语从句是在_______________，通常放在主句谓语动词______,表示_______。归纳总结：主语从句是在_______________，通常放在主句谓语动词______,表示_______。引导主语从句的连词有（基本参照宾从，请列举）：从属连词that,whether连接代词

who(ever),whom(ever),which(ever),what(ever)，whose连接副词where(ever),when(ever),why,how(ever)

整个大句子作主语之前一件事思考：这些连词在主语从句（小句子）中是否充当成分，有无意义？1)_________sheisfromisaquestion.2)_________we’llgooutdependsontheweather.3)_______dinosaursdiedoutremainsamystery.4)_______hewillcomeiscertain.5)______causedhisdeathisstillunknown.6)______hesaidmadememad.7)______wasresponsiblefo(对...负责)rtheaccidentisnotclear.8)__________leavestheroomlastshouldturnoffthelights.9）————themeetingwillbeheldisnotknown.WhereWhetherWhyThatWhatWhatWhoWhoeverWhen/Where/Why/How(由语境决定)1.连词:that,whether；（___________________）2.连接代词:who,whose,whom,what,which等；（___________________）3.连接副词where,when,how,why等。（_________________________）主语从句引导词的选择思考：这些连词在主语从句中是否充当成分，有无意义？不作成分，不可省略作主语，宾语，定语，表语作状语（时间，地点，方式，原因）此为正常的身材比例

为了使句子保持平衡，常用__来代替主语从句，而把主语从句放到______，尤其是连词that引导的主语从句常用于如下各种句式中。it后面Thatastormiscomingisreported.主语—————————————————————————————谓语头长脚短Itisreported

thatastormiscoming.头短脚长

由that引导的主语从句有时为了使句子结构平衡,避免“头重脚轻”,常用it

作形式主语,而把从句放在后面。例如:

1.That

hewillrefusethisgiftisimpossible._______________________________________2.Thattheyshouldlikeeachotherisnatural._____________________________________*it为形式主语Itisnaturalthattheyshouldlikeeachother.Itisimpossiblethathewillrefusethisgift.Task3是不是所有的主语从句都放在句首呢?有特殊情况吗?知识拓展：你能举例出用it作形式主语的常用句型吗？

It+be+adj.+that....e.g.Itisimpossiblethatyoucanfly.=Thatyoucanflyisimpossible.你能飞这是不可能的。真正的主语其实是youcanfly(这件事)，It作形式主语就代表了youcanfly这件事。It+be+n.+that...e.g._______________________________________________It+be+done+that...e.g._______________________________________________It+v.+that...e.g._______________________________________________Itisapitythat....Itisatruththat....Itwassaidthat....Itisbelievedthat....Ithappenedthat........是个遗憾....是个事实据说....人们认为........发生了框出主语从句的部分，比如：Thatlighttravelsfasterthansoundiscommonknowledge.1.Thatheisgood-lookingiswell-knownamongus.2.Whetherthemeetingwillbeputoffhasnotbeendecidedyet.3.Itwasrequested（要求)thateveryoneshouldmadeaspeechatthemeetingforthewholeclass.Whetheris需要注意的地方？travelsisiswillbeputoffhasnotbeendecided

wasrequestedshouldmade

请找出谓语动词并翻译整个句子例1).Thathewontheprizesurprisedus.__他赢得了比赛(这件事)使我们惊讶。2).Whetherhewillgotherehasnotbeendecided._______________________________________________3).Whowilltakepartinthemeetingisstillunderdiscussion._____________________________________________4）WhatmattersmostinlearningEnglishisenoughpractice._____________________________________________5).Howheworkedouttheprobleminterestedus._______________________________________________他去不去那(事)还没有被决定。谁将参加会议(事)还在讨论中。在学英语中最重要的(事)就是足够的练习。他是如何解决这个问题的(事)使我们很感兴趣。1.我们何时举行运动会还没有决定。________weshallholdoursportsmeetingisnotdecided.2.我不知道昨天谁打破了玻璃。Idon’tknow_________broketheglassyesterday.3.我不知道他长的什么样子。Ihavenoidea_________helookslike.4.这就是我忘记眼镜的地方。Thisis_________Ileftmyglasses.5.他迟到的原因是因为他的车坏了。Thereason______hewaslatewasthathiscarbrokedownontheway.Whenwhowhatwherewhy6.无论谁最后一个离开房间都应该关灯。____________leavestheroomlastoughttoturnoffthelights.7.有一个疑问就是他们如何成功去月球的。Thereisadoubt________theymanagedtotraveltothemoon.8.不管他妈妈给他什么，这个小男孩都吃。Thelittleboyate_____hismothergavehim.9.他们是男性还是女性不重要。Thequestionof__________theyaremaleorfemaleisnotimportant.10.很可能他偷了小车。Itispossible_______hehasstolenthecar.Whoeverhowwhatwhetherthat四、用形式主语it改写下例句子。（每小题2分，共10分）例`.Whenwewillholdthemeeting
