怎么区分

what did you do 与what were you doing怎么区分
What did you do :你做过什么,是一般过去时态,表示动作在现在这个时间点已经结束,
What were you doing:你过去一直在做什么,是过去进行时态,指在过去某段时间里一直持续的动作.
GOOD LUCK !

what did you do ? 意思是你过去的工作是什么? 问的是职业
what were you doing?你刚才在做什么。问的是简单过去的事实

what did you do,有做过什么?
what were you doing,(在过去的某个时间)你正在做什么
祝楼主更上一层楼
