Which do you prefer, lamb chops or pork chops? 你比较喜欢羊排，还是猪排？

finely [ˈfaɪnli] adv.成颗粒；细微地；细小地；华丽地

筷子单词：chopsticks，是由chop延申而来的。

chop：切、砍；stick：棍子；

chop(切) + stick(棍子) +s (复数) = chopsticks

所以在英美人看来，咱们使用的筷子，就是切东西的棍子。

【总结】

chip：指的是碎片、切成碎片；

chop：指的是切、砍，尤其指砍骨肉相连的东西。

共同之处：都有“碎”的含义。

不同之处：在于“碎”的程度不同，我们可以这样简单联想记忆：chip和chop的区别在于一个是i，一个是o，i比较瘦，o比较胖，那么chip的结果就是变成碎片，chop的结果就是变成块状或者小碎块状。
