I‘ll tell him to ask my permission before he goes out alone to ask为什么不能
问题描述：
I‘ll tell him to ask my permission before he goes out alone to ask为什么不能
是asking（如果tell后加宾语从句）
答
tell sb to do sth 告诉某人做某事
如果tell要跟从句得这样
I'll tell him that he should ask for my permission before he goes out aloneasking不能动名词做主语吗在这个句子里不行，因为这个句子用的就是tell sb to do sth的结构
