我的问题是but转折后but they are hungry creatures,not content with only three meals a day
为什么hungry creatures后面直接可以跟not content with only three meals a day 这句话是什么语法成分>?,
我的理解是第2句not content with.a day 为了避免重复 省略了they are 还有一种理解就是not content with...a day 作原因状语 但是原因状语接在句子后面的很少见 不是很确定.希望高手能讲这里的语法讲给我听听
我在语法书上看到这句话是作状语.什么状语请问
not content with three meals a day,they are hungry creatures
not content with three meals a day 是否是原因状语从句>?放在后面?

我的理解they are hungry creatures,not content with only three meals a day听起来就是对的句子 也很顺 第一句讲了他们是饥饿的野兽 第二句不需要重复讲‘他们’因为已经明白是讲前提 用了,而不是.not content with only three meals a day 意思就是3餐一天是不足够的‘对他们’已经不需要再提

伴随状语吧，解释一种状态
