这儿的FOR是作“因为”的意思讲,因为某人做了某事for sb do sth,因为某人没做某事而道歉for sb not to do sth

not在动词之前

being 的否定式是not being. 因此，being not 就错了。

one's doing sth 是一个动名词短语，所以her not being abkle to attend在这里是作为一个名词短语出现的。至于her being not able to attend 不正确的原因：being able to attend 是一个整体，也就是一个动名词短语，not表否定，而her being not able to attend 只是一个v_ing形式
