主语从句（SubjectClause）

定义：用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的连接词有：连词that,whether；连接代词who,what和which；连接副词when,where,how和why。1.连接词：Thatshelefthimcuthimtotheheart.Thathewillcomeiscertain.Whetheritwillpleasethemisnoteasytosay.Itisnoteasytosaywhetheritwillpleasethem.1）从属连词：that，whether等.that引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。由whether及其他连词引导的主语从句放在句首，句后都可。

既引导主语从句，又充当句子成分。Whyhediditremainsamystery.Whentheywillstartisnotknownyet.Howhebecameagreatscientistisknowntousall.3)连接副词when，where，how，why既引导主语从句，又充当句子成分。。2.位置：主语从句可以前置，也可以后置。用it做形式主语，而把主语从句放在句末，常用下面几种句型。1）It+be+表语+主语从句表语：（名词，形容词，过去分词）Itisafact(ashame,apity,goodnews…)that…Itisstilluncertainwhetherheiscomingornot.ItisanhonourthatIwasinvitedtoattendthemeeting.ItissaidthatMr.GreenhasarrivedinBeijing.ItisreportedthatChinahassentanothermanmadeearthsatelliteintoorbit.2）It+不及物动词+主语从句Itseemed(happened,doesn’tmatter,hasturnedout)that…Ithappensthattheywereabsent.ItseemsthatAliceisnotcomingtothepartyatall.Itdoesn’tmatterwhethershewillcomeornot.Itmakesnodifferencewhereweshallhavethemeeting.IthasbeendecidedthattheexhibitionwillnotopenonSundays.3)It+及物动词（被动语态）+主语从句注意:1）主语从句在句首时，必须由连接词引导，不能省略这些连接词；但是如果用it做形式主语，而把主语从句放在句末时，从属连词that可以省略。误：Theyshouldlikeeachotherisnatural.正：Thattheyshouldlikeeachotherisnatural.正：Itisnaturalthattheyshouldlikeeachother.误：IfMaryreallyheardhimisreallydoubtful.正：ItwasdoubtfulifMaryreallyheardhim.2)如果主语从句放在句首，不能用if引导，但是如果用it做形式主语，而把主语从句放在句末时，也可以用if引导。3).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\”的形式,should有时可以省略。4)在It+be+suggested/advised/ordered/requested/insisted/required中,that从句的谓语也应该用\“should+动词原形\”的形式,should有时可以省略。3.主语从句需注意的问题WhatsheisafraidofistheirtakinghertoParis.(Whatissheafraidof…Wrong)Thattheyhaven’tphonedisstrange.(1)主语从句中用陈述语序;(2)主语从句后谓语动词用第三人称单数;(3)that引导的主语从句中，that在句首时不可被省略。Thatpricewillgoupiscertain.4.what与that在引导主语从句时的区别what引导主语从句时在从句中充当句子成分，如主语．宾语．表语，而that则不然。例如：

1)Whatyousaidyesterdayisright.2)Thatsheisstillaliveisaconsolation.What在此引导主语从句,又做said的宾语。That只起连接作用,不做成分。1.Whereshallwespendtheholidayisn’tdecided.2.Youhavemadeamistakeisafact.3.Thatiscertainthatwecanwin.4.Nomatterwholeavestheroomlastoughttoturnoffthelights.5.Itisimportantthatastudentlearnsaforeignlanguage.weshallThatyouhaveItisWhoevershouldlearn改错练习Ireadaboutitinsomebookorother,doesitmatter_______itwas?A．whereB．whatC．how
