英语动词的过去式有规则变化和不规则变化两种。其中，不规则变化的动词需要我们特别注意，因为它们的过去式形式并不遵循“加-ed”的规则。
下面列出了一些常见的不规则变化动词及其过去式形式：
| 基本形式 | 过去式形式 | | ------------- |:-------------:| | be | was / were | | become | became | | begin | began | | break | broke | | bring | brought | | build | built | | buy | bought | | catch | caught | | choose | chose | | come | came | | do | did | | draw | drew | | drink | drank | | drive | drove | | eat | ate | | fall | fell | | feel | felt | | find | found | | fly | flew | | get | got | | give | gave | | go | went | | grow | grew | | have | had | | hear | heard | | hide | hid | | hit | hit | | hold | held | | keep | kept | | know | knew | | leave | left | | lend | lent | | let | let | | lose | lost | | make | made | | meet | met | | pay | paid | | put | put | | read | read | | ride | rode | | run | ran | | say | said | | see | saw | | sell | sold | | send | sent | | set | set | | shake | shook | | show | showed | | sing | sang | | sit | sat | | sleep | slept | | speak | spoke | | spend | spent | | stand | stood | | swim | swam | | take | took | | teach | taught | | tell | told | | think | thought | | understand | understood | | wake | woke | | wear | wore | | win | won | | write | wrote |
以上列出的动词都是实义动词，它们的过去式形式的变化并没有特别的规律，需要我们多多练习记忆。在英语学习中，熟记这些不规则变化动词的过去式形式是非常重要的一步，它们常常出现在英语听力、阅读和写作中。
