时间状语 last night 表示过去，动词应用过去式；grind 是不规则动词，过去式为 ground，不能用原形 grind。
Not this

Use this
I bought some ground beef.
表达“碎牛肉”时英语有固定搭配 ground beef，源于 grind 的过去分词 ground；grinded 虽是 ground 之外的一种过去分词形式，但在这个惯用搭配中不用，不能按规则动词类推成 grinded beef。
Not this

Use this

grind 表示“刻苦、费力地持续做（功课等）”时是不及物动词，常用 grind away at something；直接把 homework 作宾语是汉语“啃功课”的直译，不符合英语搭配。
