( H$ H$ f: w3 e6 b7 s4 U 名词性从句$ c& Y- b t# C) Z2 a0 J5 d
在主从复合句中,从句可以充当主句的主语、表语、宾语或同位语。由于在多数情况下,主语、表语、宾语或同位语这四种句子成分由名词性词类充当,所以,我们把这些作用相当于名词的从句统称为名词性从句,把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。也就是说充当什么成分就叫什么从句。名词性从句由连接词(或关联词)引导。& ?% X. D& e# m

疑问词(who, whom, whose, what, which, where, why, when, how)可以引导主语、宾语和表语从句。
