did是do的过去式，作为助动词时用在行为动词过去式的一般疑问句和否定句中，was是be动词am和is的过去式如：I did my homework last night.Did you do your homework last night.？(一般疑问句)I didn't do my homework last night.(否定句)He was a student last year.

did作为一般过去式助动词，常用在一般疑问句和否定句中Did you go to work yetserday? I did not go to work yesterdy.was是be动词过去式 was作为实义动词是说过去某人或者某物的状态，身份I was a student ten years ago.was也可以作为助动词，比如现在进行时过去式助动词，比如： I was doing my homework at 22:00 yeterday
