They spent half an hour packing their bags.spend time (in) doing sth 是固定结构（in往往省略）,这里不用过去完成时.过去完成时用来表示“在过去的某个动作之前已完成的动作,也就是”过去的过去”.When we arrived at the station, the train had already left.======以下答案可供参考======供参考答案1:They spent half an hour (packing)their bags sb spend (times...)in doing sth 或sb spend sth on doing sth供参考答案2:packing
