规则动词的变化规律

一般情况下，动词词尾加 -ed，如worked played wanted acted；

以不发音的 -e 结尾动词，动词词尾加 -d，如 lived moved decided declined hoped judged raised wiped；

以辅音字母 + y结尾的.动词，把-y变为-i 再加-ed，如；studied tried copied justified cried carried embodied emptied；

以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如stopped begged fretted dragged dropped planned dotted dripped。（仅供参考）
