我来补答
解题思路: 整个句子是一个主系表结构,主语是the reason ,is是系词,obvious做表语。 why做关系副词,引导一个定语从句,限定先行词the reason 。
解题过程:
The reason (why he was late )is obvious.
此句是一个主从复合句。why做关系副词,引导一个定语从句,先行词是the reason ,he was late是定语从句,限定先行词。意思是“他迟到的原因”。在这个定语从句(The reason why he was late )中,先行词the reason,在从句he was late中做原因状语。
整个句子是一个主系表结构,主语是the reason ,is是系词,obvious做表语。
最终答案:略
