请问老师：
问题1、So one important thing was that the rooms were arranged around a chimney in the center of the house, which could provide heat for the whole house through flues, uh, small air passageways into each room, as opposed to having a fireplace in every room, which would require more cleaning and make the air inside the house dirtier.
请问：small air passageways into each room算是flues的同位语还是非限制性定语？as opposed to引导的是什么状语，其中as是什么词性，这个短语能拆开剖析吗？
问题二 ：The mines were fairly remote, so there was no way to bring coal or other fuel to keep the fires going.
请问：to bring coal or other fuel我的理解是way的定语，但to keep the fires going是目的状语还是coal or other fuel的定语呢？若是目的状语，那样逻辑主语是什么，一般仿佛不定式的逻辑主语是句子主语或者是for sb/sth加在不定式前面，但这里是there be句型，我没办法理解？除此之外目的状语是否必须要找到对应的逻辑主语才成立呢？？

【答】flues 和small air passageways，是同位语，后者讲解前者，说明其内容。两个名词被逗号隔开，如何能成为定语呢？记住：同位语的主要用途，是讲解说明前文的。我用红色描述一下，你就了解了：through flues（= small air passageways） into each room
as opposed to：不再作结构剖析了。仅需记住、会用即可。意为：相对于；与…相反；而不是。

【答】你的理解正确：to bring coal or other fuel是way的定语。除此之外，to keep the fires going 是coal or other fuel的定语。
