1. 名词性从句： 例句：Whatever she said was true. 解释：此句为名词性从句，其中的“whatever（无论什么）”是一个名词，它指代一句话，换句话说，“whatever she said”就相当于“the thing she said”。 2. 定语从句： 例句：The man who comes here every day is my uncle. 解释：此句中的“who comes here every day”为定语从句，它修饰主句中的名词“The man”，翻译过来就是：每天来这里的那个人是我的叔叔。 3. 状语从句： 例句：He suddenly disappeared when I looked away. 解释：此句中的“when I looked away”为状语从句，它修饰主句中的动词“disappeared”，翻译过来就是：当我把视线移开时，他突然消失了。 拓展知识：除了以上三种从句，还有其他一些从句，如并列从句、同位语从句、目的状语从句、结果状语从句等。比如： 并列从句：He spoke slowly and clearly. 同位语从句：His promise, that he would come back soon, made me happy. 目的状语从句：He left early so that he could catch the train. 结果状语从句：He worked hard, so he passed the exam.
