◆名词性从句专项训练名词性从句是指初中学过的宾语从句和高中阶段最近所学的主语从句、表语从句以及同位语从句。宾语从句和主语从句容易理解。顾名思义，宾语从句是指由一个完整句子来充当宾语。主语从句是指由一个完整句子来充当主语。表语从句是指放在连系动词之后充当表语的完整句子。习惯上，称连系动词后面的成分为表语。常见的连系动词有:be，keep(保持),grow(变得),become(变得;成为;),get(变得),stay(保持),remain(仍然是;保持;),look(看起来),sound(听起来),smell(闻起来),taste(尝起来),feel(感觉),seem(看起来),go(变得),turn(变得)等。连系动词没有进行时态和被动语态。同位语从句是指由一个完整句子来解释说明某个抽象名词的具体内容。常见的此类抽象名词有:idea，thought，hope，news，possibility（可能性）fact，belief（观点/信念）等。当陈述句作名词性从句时，除了作宾语从句that可以省略以外，其余情形都不能省略。当一般疑问句作名词性从句时，除了在宾语从句中whether与if可以通用外，其余名词性从句均只能用whether。所有的特殊问句在作名词性从句时，均需用陈述语序。同位语从句1.WearesurprisedtolearnthefactthatCanada’spopulationisonlyslightlyover30million(加拿大只有3千万人口稍多一点).2.Yousayyoudon’thaveamobilephone.Howdoyouexplainthefactthatyouarechargingthemobilephone(你正在给手机充电)?3.Ihavenoideawhetherhewillpasstheexam(他将是否会通过考试).4.Thethoughtthatwewillbeabletovisitthemooninthenearfuture(我们在不久的将来能游览月球)isexciting.5.Theideathatwecangrowvegetablesonthesea(我们可以在海上种蔬菜)seemsstrange.6.Ihavenoideawhyhecheatedintheexam(他为什么要考试舞弊).7.Eachcultureandreligionhasitsownideahowtheearthbegan(地球是如何起源的).8.Iamsurethatthereisstillhopethatwewillwinthematch(我们会赢得这场比赛).9.Thebeliefthattheearthisthecentreoftheuniverse(地球是宇宙的中心的)seemsstupid.10.Thepossibilitythattherewillbeanearthquake(将有一场地震的)terrifiesme.11.Hehasmadeapromisethathewillnotplaycomputergames(他不再玩电脑游戏).12.ThereisnodoubtthatCanadahasmorefreshwaterthananyothercountryintheworld(加拿大比世界上其他任何一个国家的淡水资源要多).主语从句1.WhathappenedtotheAmberRoom(琥珀屋身上所发生的事)remainsamystery.2.Whoeverbreakstherule(任何一个违规的人)willbepunished.3.Itiswisethatyoustopyoursonfromplayingcomputergamesintime(你及时阻止你儿子玩电脑游戏).4.WhetherhewillflytoJapannextweek(他下周是否乘飞机去日本)hasn’tbeendecided.5.Howtheuniversebegan(宇宙是如何起源的)remainsamystery.6.Whatmanyscientistsbelieve(许多科学家所认同的)isthatwaterallowedtheearthtodissolveharmfulgasesandacidsintotheoceansandseas.7.Whatimpressesmemost(最使我印象深刻的)isthatCanadaisanemptycountry.8.WhatIknowaboutCanada(我对加拿大所了解的)isthatbothEnglishandFrencharespokeninCanada.9.Itiswell-knownthatVancouverissurroundedbymountainsandthePacificOcean(温哥华被高山和太平洋包围).10.ItisarulethatweshouldwearourschooluniformsonMonday(我们应该在周一穿校服).11.Whydinosaursdiedoutsuddenly(恐龙为什么突然灭绝)remainsamystery.12.WhateverLinTaodoes(林涛所做的任何事)doesn’tsatisfyhisboss,thushedecidestogiveuphisjob.表语从句1.Theproblemisthatnoneofuscanunderstandhisdialect(我们当中没有人能理解他的方言).2.Thereasonisthatwestayeduplatelastnight(我们昨晚熬夜很深).3.Theproblemiswhereweshouldplacethecomputer(我们应该把电脑放在哪里).4.Itisbecausehemissedthefirstbus(因为他错过了头班车).5.ThatwaswhyIquarreledwithher(我为什么与她争吵).6.WhatsurprisesmemostisthatCanada’spopulationisonlyslightlyover30million(加拿大的人口只有3千万稍多一点).7.Myworryiswhetherhewillpasstheexam(...
