Each child in Heaven's playground knows each other child by name.
They choose up sides as all take part in some exciting game
Like Hide=and=Seek, Red Rover, Cops and Robbers, Pris'ner's Base.
Our Lord is glad to referee their every game and race.
[John Bernard Kelly, "Heaven is a Circus," 1900]
英语中有许多名词cop，有些是古旧的或过时的，许多名词与古英语cop"top，summit"有或多或少的联系，这与 cup (n.)的来源有关。
