我确实知道，可不可以换成过去式为，i did know that

可以。
表示对过去时的强调！

换成过去式一般是： I knew that

i did know that是过去式，但是是起强调作用

强调主语：I knew that, he knew that but she had no idea
=It was just the two of us who knew

强调动词 know：I did know that (at the time but still i wouldn't give in)

不可以换
只能用do+动词原形表示 强调 我确实知道，”我确实知道”怎么过去时？我曾经确实知道？还是我确实曾经知道？严格地说i do know that不会有过去时出现

不可以
只能用do+动词原形表示 强调

我觉得不可以!!强调没有过去式的说法,只能在从句里换"过去式"
