过去式英文是past tense。
过去式（past tense）是英语语法的一种，表示过去某个时间里发生的动作或状态。一般过去式的动词通常用动词原形的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。
定义
1、过去发生的而已经结束的动作需要用一般过去式来表示。
2、表示过去某个时间里发生的动作或状态。
【过去时态】表示行为、动作和状态在各种时间条件下的动词形式。
【过去时态结构】是指过去时态下的动词形式的语法构成。
动词变化规则
1、一般动词直接加-ed，例如：look-looked；
2、以哑e结尾的动词直接加-d，例如：dance-danced；
3、辅音字母加y结尾的，变y为i再加ed，例如：study-studied；
4、以重读闭音节结尾，末尾只有一个辅音字母，双写这个辅音字母加-ed，例如：skip-skipped；
5、以c结尾的动词，要变c为ck，再加-ed；
6、以l结尾的动词，若以非重读音节结尾，则末尾的字母双写与不双写均可。其中不双写的是美式拼写。例如：travel-travelled/traveled（美）；
7、部分以-p结尾的动词同样遵循第6条，这类词多由“前缀+名词”构成。例如：worship-worshipped/worshiped（美）、handicap-handicapped/handicaped（美）。
注：英语26个字母中，除了a，e，i，o，u 这几个元音字母外，其他都是辅音字母。
