独立主格疑问：It being +名词（代词）
It being +名词（代词）
如：
It being Christmas,the government offices were closed.由于圣诞节的缘故,*机关都休息.
It being a holiday,all the shops were shut.由于今天是假日,所有商店都关门了.
不太懂.这里的独立主格可以改成什么?
不能省略being (having been)的情形在下列两种情况下，独立主格结构中的being（或having been）不能省略。
(1) 独立主格的逻辑主语是代词时。如：It being Sunday,we went to church.因为是星期天，我们去了做礼拜。
(2)在There being＋名词的结构中。如：There being no bus,we had to go home on foot.因为没有公共汽车，所以我们不得不步行回家。
上面指的是独立主格改成状语从句，怎么改
答
it是形式主语
只有两个*的主语不一致的时候采用独立主格结构
It being Christmas,the government offices were closed
这句话的前半句主语是圣诞节,后半句主语是*,it只是形式上的主语
It being +名词（代词）这只是一个独立主格结构的特殊现象,记住就好
这句话也可以改成 Christman was coming,the government offices were closed.
下一句同理,我就不说了
