英语 宾语从句中为何不用ago而是 before
例 he told me that he had seen his father two days ago or before

英语 宾语从句中为何不用ago而是 before例 he told me that he had seen his father two days ago or before
你可以说2 days ago,也可以说before 2 days,但在完成时中常只单独用BEFORE,例子:I HAVE MET HER BOFORE.

before是介词,动词介词才可以加宾语呀
ago是副词,副词后不可以家宾语呀

就是不用的吧,
个人觉得语法这个东西,有什么太过深究也没意思啦``记住就好啦
