定语从句与名词性从句中的同位语从句
同位语从句和定语从句一样通常都放在由名词充当的先行词后面,
且其先行词和关联词特点与定语从句先行词及关联词特点十分相似,极易混淆,不过两者的区别还是十分明显的。

when, where, how, why
定语从句
同位语从句
1.从句性质不同
同位语从句属于名词性从句,是用来进一步解释或补充说明前面的名词;
而定语从句是用来说明先行词的性质或特征,起修饰或限制的作用,与先行词的关系是修饰与被修饰的关系,从句相当于形容词。
2.同位语从句经常用于下列有限的几个词后： hope（希望），idea（想法）， news（消息）， order（命令）， fact（事实）， question（问题），reason（理由），belief（相信），doubt（怀疑），evidence（根据），conclusion（结论），truth（真理），result（结果）等。
3.引导词that在同位语从句中不作句子成分；而在定语从句中必作句子成分，是从句所修饰的词的替代词。
语从句）

4.what, how, whether等不能用引导定语从句，但可用于引导同位语从句。

whatever 和 whoever 的意思是“无论什么”“无论谁”用所引导的不是疑问句式，而是表示假设条件的句子 ，而who，what是疑问词，分别提问“谁”“什么”
Who
Whoever
what=the thing(s) which 为特指概念。
whatever= anything that 为泛指概念，用于非肯定语境。
本句中主句谓语为一般过去时，表示确实发生的事件，为肯定语境，故不能用anything that.
