名词性从句的引导词
名词性从句的引导词的基本用法。
1、用于引导名词性从句的引导词有以下几类:
连接代词: what, which, who, whom, whose
连接副词: when, where, why, how
连接连词: that (宾语从句或表语从句中"that"有时可以省略);whether,if (均表示“是否”表明从句内容的不确定性);as if ,as though (均表示“好像”,“似乎”)
2、what, which在从句中作主语、宾语、表语或定语;who在从句中作主语、表语;whom在从句中作宾语;whose在从句中作定语;when, where, why, how在从句中分别作时间状语、地点状语、原因状语、方式状语。
3、what作连接代词引导的名词性从句既可以表示一个问“什么……?”的问题, 也可以表示相当于“名词/代词+关系代词引导的定语从句”结构的意思, 这种特殊用法在语法上被称作“关系代词型的what”。
