怎么区分定语从句,谓语从句,同位语从句

没有谓语从句的。

定语从句就是修饰前半部分的内容,有关系代词 who that which whom 和 关系副词 when why where引导。

跟小明讲话那位是我语文老师。The person who/that is talking with XIAOMING is my chinese teacher.就举一例,其余去看语法书。这句话中关系代词用who和that都行,who that在定语从句中充当主语。

同位语从句通常有that 引导,有时也有how when =.同位语从句的引导词跟它前面的名词的内容是一样,相等的。如:我听到我同学获奖的消息。I heard the news that my classmate had won the prize.句中消息就是同学获奖,获奖就是这个消息。

只能简单叙述,还要靠你自己去揣摩。找个老师专门补下从句。
