,防止”头重脚轻”,惯用

作

，从而把主语从句放在

．

句首保持平衡

1)Itis+n.+that

Itisapity/shamethat...可惜是……

Itisasurprisethat…令人吃惊是…

Itisafactthat…事实是…Itiscommonknowledgethat……是常识

找出以下句子中错误，并总结规律例1.Whenwillhecomeisnotknown.规律一、主语从句一律用陈说语序，即主语在前，谓语在后。正：Whenhewillcomeisnotknown.26/72主语从句规律：

例2.Hewillnotcometothemeetingthiseveningistrue.正：Thathewillnotcometothemeetingthiseveningistrue.规律二、连词that在从句中无实际意义，但不能省略。27/72主语从句规律：例3.Ifthemeetingwillbeputoffhasnotbeendecidedyet.正：Whetherthemeetingwillbeputoffhasnotbeendecidedyet.规律三、whether能够引导主语从句，放在句首，但if不能28/72主语从句规律：

例4.

Thatwhetherhewillhelpothersisafact.正：Thathewillhelpothersisafact.规律四、主语从句中连词不能重合使用。29/72主语从句规律：例5.

Whenhewillcomeareapuzzle.正：Whenhewillcomeisapuzzle.规律五、含主语从句主句谓语动词多用单数第三人称形式。30/72主语从句规律：1.Whatheneedsisthatbook.2.Whatheneedsaresomebooks.规律六、what引导主语从句，可依据表语决定主句动词单复数形式。31/72规律七、主语从句为了防止头重脚轻现象，用it做形式主语，而把从句放在后面。Thattheearthturnsaroundthesunisknowntoall.

Itisknowntoallthattheearthturnsaroundthesun.32/72主语从句三要素hebecameagreatscientistisknowntousall.Iswhatyoutoldmereallytrue?谓语动词多用单数从句用陈说语序不能省略关联词How33/72在主语从句中，谓语普通用单数。1、不论他说什么都不主要。Whateverhesaysisofnoimportance.2、不论谁说这话都不对。Whoeversaysthisiswrong．但谓语动词用单数还是复数，不可一概而论，而要视句子意义而定。

WhatIneedismoney.WhatIneedarebooks.34/72注意事项1.主语从句位于句首时必须由连接词引导。2.主语从句位于句末时引导词that可省略。3.主语从句位于句首时,不能用if引导。4.主语从句位于句末时,能够用if引导。35/72找犯错误，并给出理由：1.Whereshallwespendtheholidayisn’tdecided.2.Youhavemadeamistakeisafact.

3.Ifthepolicemanwillcomeisnotcertain.4.Thatiscertainthatwecanwin.

主语从句需注意问题(1)主语从句中用陈说语序WhatsheisafraidofistheirtakinghertoParis.(Whatissheafraidof…Wrong)(2)主语从句后谓语动词普通用第三人称单数（特殊情况见练习册P60）Thattheyhaven’tphonedisstrange.(3)that引导主语从句中，that不可被省略Thatpricewillgoupiscertain.40/724).用于Itisimportant/natural/necessary/impossiblethat...句型中,主语从句应使用虚拟语气,谓语动词用\“should+动词原形\”形式,should有时能够省略。5)It+be+suggested/advised/ordered/requested/insisted/required

中,that从句谓语也应该用\“should+动词原形\”形式,should有时能够省略。41/72Step4.小试牛刀42/721._____youdon’tlikehimisnoneofmybusiness.（与我无关）2._____hesaidatthemeetingsurprisedeveryone.3.________theOlympicGameswillbeheldinBeijingisnotknownyet.4.________we’llgofishingtomorrowdependsontheweather.5.________leavestheroomlastoughttoturnoffthelights.ThatWhatWhetherWhetherWhoever43/721.他是否是我孩子依然(remain)是个问题。___________________remainsaquestion.Whetherheismychild补全句子练习44/72
