英语动词过去分词的变化规则可分为以下几种情况:
一、规则动词的变形规则
在动词原形后直接加 -ed
例:
- walk → walked → walked
- call → called → called
以“e”结尾的动词
直接加 -d
例:
- move → moved → moved
- live → lived → lived
以辅音字母 + y结尾的动词
将 y变为 i,再加 -ed
例:
- study → studied → studied
- stop → stopped → stopped
重读闭音节,末尾只有一个辅音字母
先双写该辅音字母,再加 -ed
例:
- plan → stopped → stopped
- help → helped → helped
二、不规则动词的变形规则
不规则动词的过去分词需单独记忆,常见形式包括:
单复数同形:
cast → cast → cast
过去分词与过去式相同:
think → thought → thought
特殊变形:
buy → bought → bought
三、发音注意事项
-ed发音规则:
清辅音后读 [t](如 help[helped])
浊辅音/元音后读 (如 move[moved])
以 -t、 -d、 -l、 -th结尾时读 [id](如 needed[needed])
四、示例汇总
| 动词原形 | 过去式 | 过去分词 |
|----------|--------|----------|
| work | worked | worked |
| study| studied | studied |
| stop | stopped | stopped |
| help | helped | helped |
| think| thought | thought |
| buy | bought | bought |
通过以上规则,大多数动词的过去分词变形可通过加 -ed实现,但需注意不规则动词的特殊形式。
