1、精选优质文档-倾情为你奉上名词性从句的重点、难点、考点：名词性从句在功能上相当于名词名词性从句的定义:在复合句中起名词作用的从句叫名词性从句(Noun Clauses）。名词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，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。(一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语
2、。3、连接词：that, whether, if, as if。 that 无词义，在从句中不担任成分，有时可省略；as if（好象）虽有词义，但在从句中不担任成分。注意：连词的选用： 依据“缺什么补什么”原则确定正确的连词。如果句子中缺主语，指人用who，指物用what；如缺宾语，指人用whom，指物用what；如缺时间状语用when；地点状语用where；原因状语用why；方式状语用how；定语用what或which；什么都不缺用that。whether 和if（是否），1.
