1、第三讲 名词性从句第一课时 知识过关课1.主语从句作主语,主句谓语动词通常用单数;为使句子平衡,常用it作形式主语。2.表语从句还可以用asif,asthough引导。3.表示“是否”,引导宾语从句时可用if或whether,但在介词后或直接与ornot连用时,只能用whether引导;引导表语从句、同位语从句或位于句首的主语从句时,只能用whether,不用if。4.同位语从句一般放在fact,news,idea,promise,suggestion,advice等抽象名词之后,说明或解释这些
2、抽象名词的具体内容。多用that引导,不能由which引导。5.当宾语从句又带有补语时,要用it作形式宾语。6.在表示“建议”“命令”“要求”,如advice,suggestion,proposal,order,demand,request等词后的名词性从句,其谓语通常用“(should+)动词原形”。7.that引导名词性从句时,不作任何句子成分;但that引导定语从句时,它代表先行词,而且在从句中作主语、宾语或表语。Istillrememberthepromisethat__he__made
3、.我依然记得他许下的诺言。(定语从句)Thenaughtyboymadeapromisethat__he__would__never__make__a__noise.那个淘气的男孩保证说他以后再也不吵闹了。(同位语从句)8.what可引导名词性从句但不能引导定语从句。what引导名词性从句,有时相当于“the+名词+that”,表示“(所)……的”。What(=The__thing__that)yousaidwasright.你所说的是正确的。读语篇,悟语法。反复朗读下列短文,领悟画线和黑体部分
4、,思考:画线部分在全句中作何种成分,即是什么从句,该从句为什么要由这个黑体词来引导。What__worries__my__classmate__Mary__a__lot__these__days[1]isthat__she__puts__on__too__much__weight__and__she__is__frequently__ill[2].Shehassomedoubtswhether__she__eats__too__much__fast__food__high__in__fat__o
