使用独立主格结构的几点注意
1. 独立主格与状语从句的转换
当状语从句的主语与主句的主语不是指同一个对象时，可用独立主格结构取代状语从句，但不再保留连词。如：
After class was over (=Class being over / Class over), the students soon left the classroom.下课后，学生很快离开了教室。
2. 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) 独立主格结构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。
3. 通常不用物主代词或冠词
在“名词（或代词）＋介词短语”构成的独立主格结构中，一般不用形容词性物主代词和冠词。如：
Miss Smith entered the classroom, book in hand.史密斯先生走进了课室，手里拿着一本书。
