在英语中，动词的过去式有规则变化和不规则变化两种。规则变化的动词过去式是加上-ed，如walked、played、talked等。而不规则变化的动词过去式则没有固定的规则，需要记忆。
下面是一些常见的不规则动词过去式：
| 原形 | 过去式 | | --- | --- | | be | was / were | | begin | began | | break | broke | | come | came | | do | did | | eat | ate | | find | found | | give | gave | | have | had | | know | knew | | make | made | | see | saw | | take | took | | write | wrote |
从上表可以看出，不规则动词的过去式形式各不相同，需要通过记忆来掌握。但是，有一些动词的过去式和原形相同，如cut、put、set等，这些被称为同形同音词。
当我们学习英语时，需要掌握这些不规则动词的过去式，可以通过写作和口语练习来加深记忆。同时，也可以通过工具书或者应用程序来帮助记忆。
记住动词过去式不规则变化规律，可以更好地理解和运用英语语法。
