请写出进行式有哪些时态？

be doing
was were doing
has been doing

您好，进行时初衡宏携稿中阶阶段所学的进行时是现在进行时，比如
I'm having an English class，我正在上英语课，
再有就是过去进行时，
When I got home，my mother was cooking supper我到家的时候，妈咐隐册妈正在做晚饭。

现在、过去、将来

进冲竖塌行时态纤唯有：

现在进行时 (am/is/are doing)

过去进行时 (was/were doing)

将来进行时 (shall/will be doing)

过去将来进行时 (would be doing)

现在完成进行时 (have / has been doing)

将来完成进行时散圆 （shall/will have been doing）

过去完成进行时 (had been doing)

过去将来完成进行时(would have been doing)
