帮我写出这些单词的过去式

he is 、is not、are not、it is、what is 、that is、we are、she is、they are、do not?帮我写出这些单词的过去式
is, are, do 分别是系动词和助动词,
对应的过去式是was, were,did
所以:
he was、was not、were not、it was、what was
that was、 we were、 she was、they were、did not

he was ,was not , were not ,it was , what was, that was, we were, she is , they were, did not.

he was,was not,weren't (were not),it was,what was,that was,we were,she was,they were,did not。
is变成was,are变成were,do变成did。
