问题描述:

I went to the aquarium _____ my day off.A.on B.in C.with D.at

您好
当名词 morning afternoon evening last yesterday year week month 前有下面这些词修饰时前不加介词 last next this that these those every each yesterday 如 this week. next year
yesterday morning each year every day 但on the next day off这句中后面还有介词off其实是一固定结构。也就是on the ,,,day off
因此选A

答案是A。on my day off是休息日的意思,固定搭配

on
具体时间(如某一天)用 on,
