请教语法网的专家:
One of the thieves was struck by a heavy statue, but he was too busy helping himself to diamonds to notice any pain.
The raid was all over in three minutes, for the men scrambled back into the car and it moved off at a fantastic speed.
关于in+一段时间的用法,理解含义:
The raid was all over in three minutes - was all over 整体是短暂动词吗?是3分钟之内,还是3分钟之后呢?为什么?
我的困惑是这里的in three minutes 应该怎么理解?有什么方法?
