独立主格中being省略与否的问题

Question

比如以下：
His homework done, Mary decided to go shopping.
变成：
His homework being done, Mary decided to go shopping.
对不对？这两句意思一样吗？
那么什么时候可以省略呢？

另外：
The monitor being ill, we'd better put the meeting off.
中的being能否省略？？？

Answer 1

两句意思基本相同.
但是第一句强调后半句,第二句强调前半句被完成的动作.所以是否省略应该放在具体语境中.

BEING不能省略,因为ILL是形容词,如果省略就没有谓语了.
