不能...完全错误
we weren't went to zoo yesterday,we were went to the park.
应改为,we didn't go to zoo yesterday.
we went to the park.
Did he flow a kitte on sunday Yes ,he did.
才对```
至於你所说的应该是be+动词的过去分词(注意,不是过去式),是被动语态
例如
1.He was attacked yesterday.他昨天被攻击了.
attack-attacked-attacked
原形-过去式-过去分词
2.The book was written by Steven.这本书是被史提芬写的.
write-wrote-written
