过去 stayed tried added burned/burnt emailed climbed visited waited hated listened laughed
过分 stayed tried added burned/burnt emailed climbed visited waited hated listened laughed
其实英语经过几次改革不规则的过去式和过去分词已经很少了,很多不规则的都变规则了（如burn,所以建议多使用burned）.英语在不断地国际化和简化!所以有不知道的过去式和过去分词大多直接加-ed,少数有专门的不规则表.还有不要随便双写t、d,除非重音在最后一个音节.
好了,祝楼主英语水平节节高,兔年快乐!
