“ Know something front and back ”一词是指通过学习Know something front and back在专家水平上拥有完善的知识。这个成语来自于表达对know something backwards and forwards的know something backwards and forwards 。这种表述比front and back更为普遍。例子: She's read the book so many times, she knows it backwards and forwards. (她读过很多本书,所以她非常了解这本书。)例子: He knows cars front and back. (他很了解汽车。)
