while的连词作用

Thirty people have been confirmed as having died while battling a forest fire in southwest China's Sichuan Province,authorities said Monday.

老师，连词的修饰作用具体如何用，从属连词，并列连词都是连接句子，短语，词与词之间的它的修饰作用与形容词修饰名词，副词修饰动词一个原理吗？

Thirty people have been confirmed as having died while battling a forest fire in southwest China's Sichuan Province,authorities said Monday.

while引导的省略形式的时间状语从句修饰的是实意动词die, 即死亡发生在救火过程中。die用现在分词完成体是因为要表示死亡是发生在confirm之前。
