前面did后面为何不变成brought过去式

一般疑问句：在句首加did，句子中的动词过去式变回原形。如：Did Jim go home yesterday? 特殊疑问句： ⑴疑问词+did+主语+动词原形？如： What did Jim do yesterday? ⑵疑问词当主语时：疑问词+动词过去式？如：Who went to home yesterday?

还有比如does也是一样的

因为已经有了did，所以后面用原型。

因为前边变了,后边就不需要了.
是规定.

从你例出的句子，显然是个疑问句....我只能说这是英语的固定形式。疑问句中，为了保证句子的形式，英语不将动词提前，而用do（does，did）代替。后面的动词用原型。
Do you understand?
Did you understand?

你这个是疑问句

when did you do和what did you do 区别 When did you become a housewife? ------When did you _____this school? ----__________ when did you go to the school? when did you first meet her? What did you _____ when you were sick? when did you first read an english book 怎么回答有没有人听过“when did you fall” when did you fall哪里有下的? When did you last tidy your room?什么意思啊?
