关于“his mother being ill,he had to stay at home,looking after her”
his mother being ill,he had to stay at home,looking after her
这个句子中,为什么用being ill 不用was ill或者is being ill呢?
还有,looking after her与主语是什么关系,是状语从句吗?

优质解答

“his mother being ill,he had to stay at home,looking after her” 句中主语是 he 而不是 his mother；如果is/was being 那么前部分就是his mother 作主语,主语就不一致了,就错呗!其实his mother being ill是省略...
