1.-Does your brother serve in the army?
-NO,not now,but he __ in the army for eight years.
A.served B.was serving
答案是A 我的疑问是：过去式怎么可以跟一段时间啊? 还有 B为什么不可以选啊

for eight years在这里是个补充,是说他过去在军队服役过8年,这并不影响说这件事情是发生在过去的事实.重点是他过去做过这样一件事.不选B,过去进行时一个是语法错误的关系,简单点说,你直接翻译会发现不合逻辑,for eight years 已经是说过去的时间了这里,过去八年内正在...没有这样表达的
