黄霄云中国好声音盲选:when did you do that ?中do 为什么用原形不用过去式?

you did that when这个是这句话的原来位置
转换成问句 be动词或助动词要提前
所以用did you do
did就是do 的助动词形式
比如:i had lunch at 8 o'clock
转换:did you have lunch at ..............?
did已经表示过去式了!
问句中不是有did 吗?!
did已经表示过去式了.do还原
前面有了助动词,后面的动词还原为原形
因为前面有did
在一句句子中,过去式后加原形
when did you do that ?中do 为什么用原形不用过去式?
