[請益] VOA一則新聞的用法

[adgh (come true)]

And for poor kids, the loss can be as much as three months of school learning
that just disappears over the course of the summer. That’s a very
significant part of the achievement gap that separates kids from low-income
communities from kids from more affluent communities.







大致意思應該是說 成績差距會加遽較貧困與較富裕學生的差距

但我不是很理解句子的用法

為什麼會用3個from呢
