Question

Answer 1

独立主格结构一般在句子中做状语，是由一定的从句变换而来，主从句主语不一致的情况下用，结构有：n.+ to do/ doing/ done/ adj./adv./介词短语，有时还要注意时态语态（having done/having been done, to do/ to be done) 其他结构：there being / it being + n.
eg.
there being no buses, let's walk home.
it being Sunday, they had no classes.
meeting (being) over, our headmaster stepped out of the meeting room.
weather permitting, we will go out to play. = if time permits, we will go out to play.
