NounClauses名词性从句为何叫名词性从句？_______________________主语从句It作主语惯用句型有:用形式主语it主语从句常见结构用it句型翻译:表语从句注意以下表语从句中where,how,why译法宾语从句中连接词that在以下三种情况下不能省略：（1）当that从句与另一名词性从句并列作宾语时，第二个that不能省；（2）当that作介词宾语时，that不可省掉。（3）用it做形式宾语宾语从句Everyoneknewwhathappenedandthatshewasworried.Thereasonliesinthatsheworksharderthantheothersdo.whether与if辨用1).whether和if都能够引导宾语从句a..当whether后紧跟ornot时,不用if.eg:Idon’tknowwhetherornotIwillstay.b.介词后面宾语从句不能用if.eg:IworryaboutwhetherIhurtherfeeling.PracticetimeIdoubtif/whetherhewillpasstheexam.Idon’tdoubtthatwewillwinthematch.Doyoudoubtthathediditonhisown?宾语从句经常做介词宾语correction同位语从句4.Timetravelispossible./Thereisnoscientificprooffortheidea.一、同位语从句与定语从句相同之处2、两种从句都能够用that引导e.g.二、同位语从句与定语从句不一样之处2、引导从句关联词that功效不一样：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。考点之一:考查名词性从句中that与what区分考例:_______wecan'tgetseemsbetterthan_______wehave.A.What;whatB.What;thatC.That;thatD.That;what分析:(注:划线选项为最正确答案,下同.)在名词性从句中that与what区分是:that在名词性从句中不作句子成份,只起连接作用;而what在名词性从句中不但起连接作用,而且作句子成份.句子意思是:我们不能得到似乎比我们已经拥有要好.此题考查了两个名词性从句:主语从句和宾语从句,what在这两个名词性从句中都作宾语.考点之二:考查名词性从句中it作形式主语或形式宾语考例1:_______isafactthatEnglishisbeingacceptedasaninternationallanguage.A.ThereB.ThisC.ThatD.It分析:在这种名词性从句中为了保持句子平衡,往往用先行词it作形式主语或形式宾语,而把真正主语或宾语放到后面,尤其是that引导主语从句往往用先行词it作形式主语.此句也能够改写为:ThatEnglishisbeingacceptedasaninternationallanguageisafact.考例2:Ihate_______whenpeopletalkwiththeirmouthsfull.A.itB.thatC.thisD.them分析:此题考查是用先行词it作形式宾语,而把真正宾语从句放到后面.其它几个词均不能作形式宾语.考点之三:考查名词性从句语序考例:Thephotographswillshowyou_______.A.whatdoesourvillagelooklikeB.whatourvillagelookslikeC.howdoesourvillagelooklikeD.howourvillagelookslike考点之四:考查名词性从句中whether,if以及that区分考例1:_______we'llgocampingtomorrowdependsontheweather.A.IfB.WhetherC.ThatD.Where分析:句子意思是:我们明天是否去野营要视天气而定.whether与if当"是否"讲时区分是:在引导宾语从句时二者能够交换,但在引导主语从句、表语从句和同位语从句以及介词后面宾语从句或后面紧跟ornot时通常只能用whether,而不能用if.考例2:Whatthedoctorsreallydoubtis_______mymotherwillrecoverfromtheseriousdiseasesoon.A.whenB.howC.whetherD.why分析:本题句子意思是:医生真正怀疑是我母亲是否能很快从重病中恢复过来.whether引导是表语从句.考例3:Itworri
