在英语中,以前的年级可以用以下表达来表示:

previous grade: 之前的年级

例如:

She was in the previous grade when she learned about world history. (当她学习世界历史时,她在之前的年级。)

也可以用以下表达来表示:

prior grade: 之前的年级

例如:

He struggled in his prior grade, but he worked hard and was able to catch up. (他在之前的年级遇到了困难,但他努力工作并赶上了。)

这些表达都可以用来指代以前的年级,它们都来自英语中的副词,分别是"previous"和"prior"。
