独立主格用法

独立主格
特点：
1首先它不是一个“句子”，在这个结构中，没有真正的主语和谓语动词，但又在逻辑上构成主谓或主表关系
2 充当状语，表原因，条件，伴随，时间，补充。

3 它的主语与句子主语不一致。

用法
1) 名词/代词+形容词
It stood silent in the noon sunlight, its door open. （伴随）
2）名词/代词+分词
Winter coming, it gets colder and colder. （时间）
“Mars,” said the boy, turning to the man, his eyes opened wide, and his right hand raised. （伴随）
4）名词/代词（主格）+不定式
The two boys said good-b ye to each other, one to go home, the other to go to his friend’s.（时间）
5）名词/代词+介词短语
The huntsman entered the forest, gun in hand. 那位猎人手里提着枪走进了树林。

（伴随）
A 在此结构中，如果逻辑主语与介词短语中的名词都是单数名词，这些名词前不用冠词。

B 如果与with连用，名词前需要加冠词或物主代词。

He was standing there, with a pipe in his mouth.
6）名词/代词+副词
Nobody in, the thief took a lot of things away. （原因）
7）名词/代词+名词
He fought the wolf, a stick his only weapon. 他和狼搏斗着，唯一的武器是一根棍棒。

（补充）
8 以上的结构都可以加上with, 显得更加口语化。
