视力训练

　　班里正在进行“视力训练”。一个聪明伶俐的新兵被班长叫出来数远处旷野上采掘队的人数。采掘队在很远的地方，那些人看起来只是一些小点儿。但是这个新兵毫不犹豫的回答：

　　“十六个士兵和一个中士，长官。”

　　“正确。可你如何知道那儿有一个中士？”

　　“他不干活，长官。”

Visual Training

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 far away that the men appeared as mere dots, but unhesitatingly the recruit replied:

"Sexteen men and a sergeant, sir."

"Right; but how do you know there's a sergeant there?"

"He's not doing any digging, sir."
