以下是一些常见的动词过去式变化规律:
1. 规则变化(-ed)
对于许多动词,过去式是在动词词尾加上 "-ed":
- work → worked
- play → played
- want → wanted
2. 不规则变化
有些动词的过去式不规则,需要单独记忆:
- go → went
- eat → ate
- see → saw
3. 以 "e" 结尾的动词
有些以 "-e" 结尾的动词,在变为过去式时去掉 "-e" 并加上 "-d":
- dance → danced
- live → lived
- use → used
4. "y" 结尾的动词
以 "-y" 结尾的动词在变为过去式时,将 "-y" 改为 "-ied":
- study → studied
- carry → carried
5. 双写最后一个字母的动词
有些动词在变为过去式时,将最后一个字母重复一次再加 "-ed":
- stop → stopped
- plan → planned
6. "I" 变成 "a" 的动词
有一些以 "-i" 结尾的动词,变为过去式时 "i" 变为 "a",再加 "-ed":
- begin → began
- drink → drank
7. 无变化
有些动词的过去式和原形相同:
- see → saw
- go → went
- do → did
请注意,这只是一些常见规律,英语中还有许多其他动词过去式的不规则变化。要掌握动词过去式的变化,建议多阅读、多写作、多做练习,增加词汇量和熟练度。
