词性从句（一）概念
在主从复合句中，由一个从句来充当主语、表语、宾语或同位语，这样的句子因为具有名词的性质，统称为名词性从句。（二）名词性从句种类
名词性从句包括主语从句、表语从句、宾语从句和同位语从句。（三）引导词
名词性从句的引导词主要根据句子的意思来决定。所有名词性从句表示陈述语气，用that若表示疑问语气，用whwordwhowhathowwhe
wherewhichwhetherwhateverwhoeverhoweverwhereverwhicheveretc。Thathewo

3区分定语从句与同位语从句两者结构类似，都是在名词后紧跟一个从句，但定语从句的引导词必须在定语从句中充当主语或宾语，而同位语从句的引导词在从句中不充当任何成分。
