英语中动词的过去分词形式主要根据动词的结尾和发音规则变化而来。以下是主要的转换规则：
一般情况
直接在动词原形后加“-ed”。例如：
play -> played
work -> worked
look -> looked
以不发音的e结尾
只在动词原形后加“-d”。例如：
love -> loved
use -> used
face -> faced
以辅音字母加y结尾
将y变为i，再加“-ed”。例如：
try -> tried
study -> studied
cry -> cried
以重读闭音节结尾且末尾只有一个辅音字母
先双写该辅音字母，再加“-ed”。例如：
stop -> stopped
plan -> planned
permit -> permitted
以辅音字母加y结尾且y前面是元音字母
直接加“-ed”。例如：
boy -> boyed（但这种情况较为罕见）
以c结尾的动词
将c变为ck，再加“-ed”。例如：
picnic -> picnicked
traffic -> trafficked
不规则动词
不遵循上述规则，需要单独记忆。例如：
been -> been
gone -> gone
seen -> seen

love -> loved
dance -> danced

live -> lived
eat -> eaten
play -> played
