一.名词性从句的概念:
一个句子在连接词的引导下,在句子中起名词作用的句子叫名词性从句。
二.名词性从句的功能:
相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等。
Hisjobisimportant.(主语)
Whathedoesisimportant.(主语)
Thisishisjob.(表语)
Thisiswhathedoeseveryday.(表语)
Idon’tlikehisjob.(宾语)
Idon’tlikewhathedoeseveryday.(宾语)
Idon’tknowaboutthefactthatheisateacher.(同位语)
Idon’tknowabouttheman,Mr.White.(同位语)
得出结论:
因此根据它在句中不同的语法功能,名词从句又可分为四类,即:
主语从句、宾语从句、表语从句和同位语从句。
三.引导名词性从句的连接词:
1、连接代词:
who,whoever,whose,whom,whomever,what,which。
有词义,在从句中担任成分,如主语、表语、宾语、或定语等。
●Idon’tbelieve__________hehasachievedsofar.
●__________breaksthelawshouldbepunished.
2、连接副词:
when,where,why,how。
有词义,在从句中担任成分,作状语。
●__________wewillhandintheprojectwillbediscussedlater.
●Parentsarethoughttounderstand__________importanteducationistotheirchildren’sfuture.
●Thereason__________hewasabsentwasthathewasill.
3、连接词:
that,whether,if,asif,asthough。
that无词义,在从句中不担任成分,有时可省略;
if(whether),asif虽有词义,但在从句中不担任成分。
●Idon’tcareabout__________youhavemoneyornot.
●Theproblemis__________Tomisabletoarriveontime.
●__________themeetingwillbeheldhereisnotdecidedyet.
●Itlooks__________itisgoingtorain.
●Thetruthis__________hedidn’tcomefortheconcert.

四.名词性从句的类型:
1.主语从句:
在复合句中作主句的主语。
连接词有that,whether;
who,what,which;
when,where,how,why等。
如:
●__________heisafamoussingerisknowntous.
●__________hewillgotoAmericaisnotyetfixed.
●__________she’scomingornotdoesn’tmattertoomuch.
●__________broketheglassyesterdayisnotclear.
注意:
1.为避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语。
