be的过去式有两个,一个是was,另一个是were was是is 和am的过去式,were是are的过去式

不用的,be和动词往往是构成进行时或者完成时,be为过去式时,后面的动词依然用ing或者done,不用过去式。比如was doing,was done,不是was did 满意请采纳,谢谢

be动词中 am, is 的过去式都是was,are的过去式是were. 过去分词been 一般用于完成时态中。。。

主语+be+过去完成时表示被动,为被动语态。 有很多动词的过去式和它们的过去完成式一样,所以很容易弄混。 满意望采纳。:)

be动词变,be动词后边的动词应该是表示被动或者状态的,你把题放上来,情况不同,变化不同,比如过去进行时就应该是be动词过去式,动词ing

过去进行时
