What were you doing; what did you do; 它们有什么区别?

第一个是过去进行时态, 表示过去某个时候你正在做什么第二句是一般过去时态,只是说你做了什么

What were you doing?和What did you do?

两者都是提问过去式.也就是说是提问你过去所发生的事. What were you doing?的意思是“你正在做什么?” What did you do?则是说“你做了什么?” 还有什么要补充的么?

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 !

为什么是What were you doing,是过去式为什么要用doing,不是what

这个是过去进行时的固定结构,be后面是不能加原形的
