问题补充：
The army officer his men to fire as soon as the enemies came up.
A. requested
B. commanded
C. begged
D. suggested
答案：
A. requested
(答案→)B. commanded
C. begged
D. suggested
解析：句意为“那位军官命令士兵们等敌人一走近就开火射击”。command 意思是“命令，指挥”；而 request表“请求，要求”；beg“请求，乞求，恳求”；suggest“建议，暗示”。相比之下，只有 command 命令意义较强。故选B
