Question

He____for three years A)has joined the army B) has been in the army C) has been an army

这题为什么选B不选C呢？

Answer 1

您好

army是一个集体名词，军队的意思，这个句子里不可以表示个人。

be in the army= be a soldier

Answer 2

B
这里指be in the army"在部队（服役）”这个状态持续多久
C 肯定错， 因为主语是“他”， 他是军队？！显然不对。如果把C 改为 【has been a soldier"是个士兵“】就对了！！

如不明白请追问，要是满意请【采纳】

祝学习进步

Answer 3

C 应是has been an army member=has been a soldier =has been a member of the army
