看见妈妈正在打扫卫生 用英语怎么说 过去进行时看见妈妈正在打扫卫生 用英语怎么说 要过去进行时就是回忆,看见妈妈正在打扫卫生“连忙”用英语怎么说

I saw my mother cleaning the room.

I saw my mother cleaning the room.对的,SAW是感官动词,后加-ing 形式
promptly; at once; immediately连忙

两位好像说的都不对吧
好像是
I saw my mother was cleaning the room.
过去进行时是was/were doing

一楼说的不对吧
l saw my mother cleaned my room
