    4.  现在分词短语 being ... 可以作原因状语，意思是“因为”、“由于“。句子的主语通常是该分词短语的逻辑主语。如：Being a quiet sort of person,I didn't want to get involved. （因为 / 由于）我是个喜欢清静的人，所以不想介入。 (摘自《朗文当代高级英语辞典》答6版) 

    如果句子的主语不是该分词短语的逻辑主语，应该在 being 前面加上逻辑主语。如：You can't expect them to sit still for that long, children being what they are. 你不能指望他们安安静静地坐那么长时间，(因为)小孩子就是小孩子。 (摘自《朗文当代高级英语辞典》答6版) 

    5. being as 可以作连词（英国口语用法，同义词是 as）意思相当于 because 。如：

    You might as well drink it, being as you've paid for it. 还是喝了吧，（因为）你钱都付过了。 (摘自《朗文当代高级英语辞典》答6版)
