Question

这个英语句子我不懂结构
with nanny surveillance companies reporting business having doubled in the past few years.
having 为什么加ing doubled在此是过去分词还是其他的形容词?
特别是reporting business having doubled 这部分我不懂

Answer 1

你可以这样理with nanny surveillance companies which report that business have doubled in the past few years.
reporting动名词修饰companies,表示companies的动作；having动名词修饰business,表示business发生的动作
