结果状语从句分析Unfortunately,his father died, leaving the family even worse off, so Charlie spent his childhood looking after his sick mother and his brother.
这里的主干 his father died, leaving the family even worse off 作结果状语怎么理解? 不是so引导结果状语从句嘛?那主干不是作原因状语从句嘛?
主干指主谓结构,不包括状语
So这里是连词,连接并列句
并列句的意思就是,有承接原因的第二个句子,因为他父亲去世了,因此。。。
两个并列句子,不是从属关系!
