the squad were having "visual training". one smart recruit was asked by the officer to count how many men composed a digging party in a distant field. the party was so faraway that the men appeared as mere dots, but unhesitatingly the recruit replied
：班裡正在進行“視力訓練”。一個聰明伶俐的`新兵被班長叫出來數遠處曠野上採掘隊的人數。採掘隊在很遠的地方，那些人看起來只是一些小點兒。但是這個新兵毫不猶豫地回答。
"sixteen men and a sergeant , sir."
“十六個兵外加一箇中士，長官。”
"right, but how do you know there's a sergeant there?"
“正確，可是你怎麼知道那兒有一箇中士？”
"he's not doing any digging, sir."
“他不幹活，長官。”
