I received many books,many of them books,这个是独立主格 但为什么不需要在books前面加being啊

I received many books,many of them books,这个是独立主格 但为什么不需要在books前面加being啊
有些非谓语动词为什么很多都不需要加being啊?好像 So many people absent from the meeting,the meeting had to be called off.为什么不需要在absent前面加being,
答
明显的主表关系 则不需要加being
如So many people absent from the meeting这是形容词短语的独立主格结构 形容词与逻辑主语是明显的主表关系 加being属于多余
