首先你得明确先行词这个概念. 什么叫做先行词? 例,he is a hard-working student. 句子成分分别为主语,谓语,定语,表语. 变为定语从句后,he is a student who is hard-working. who 为引导词,引导定语从句修饰student. student 为先行词,也就是被修饰的词. 因此,其他从句是没有先行词的,除了定语从句和同位语从句. 给个同位语从句的例子,the news that he won the match made us surprised. the news 是先行词,that 为引导词. 再强调一下,其他从句是没有先行词的,除了定语从句和同位语从句.
