be动词过去式后动词一定要ing形式吗

be动词过去式后动词一定要ing形式吗
不一定的
be动词的过去式是 was were
如果是被动语态 后面跟的是过去分词 而不是现在分词
比如 the bike was broken

是的

要看句意而定。
e.g.
1. She was watching TV at this time last night. (was+watching体现过去进行时结构)
2. The window was broken by the boy yesterday afternoon. (was+broken体现一般过去时态的被动语态结构)

不一定的哦,要看情况
