易错句子I usually eat snack after dinner.

正确表达I usually eat a snack after dinner.

snack 是可数名词，单数形式不能单独出现，前面必须有限定词（a/an/the、my 等）。汉语说「吃零食」时名词前不带任何冠词，学生容易把这种零标记习惯直接搬进英语。这里泛指任意一次零食，用不定冠词 a。

易错句子She bought too much snacks for the party.

正确表达She bought too many snacks for the party.

snack 是可数名词，其复数 snacks 要用 many / too many / a few 来修饰，而 much / too much 只能修饰不可数名词。汉语的「太多」不区分可数与不可数，所以容易误用 much。

易错句子I often eat snacks between the meals.

正确表达I often eat snacks between meals.

between meals 是固定搭配，泛指「两餐之间」这个日常时段，用零冠词；加上 the 会指代谈话双方已知的某几顿饭，在泛泛陈述习惯的句子里不成立。汉语「两餐之间」本身不含定指，学生常按 the＝「那个」而多加了 the。
