1.概念 在句子中起名词作用的句子叫名词性从句。
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, 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。
Who will win the match is still unknown.
whichever (book) you like.
whose
• Whose表示“谁的”。 • 在句子中充当定语的成分，其后一定会加
when, where, how, why, however… when, where, how, why, however…
that的用法
• 在从句中不充当任何成分，也没有任何具体意思。 • 引导的句子相当于一个陈述句。 • 只起到连接的作用。
主语 做及物动词宾语

表语从句
位于系动词之后作表语的从句叫表语从句。 The problem is who is to pay and when we can start.
