规则动词的过去式变化如下：

1.一般情况下，一般在动词原形后加''-ed'' ，如： work-worked , play-played , want-wanted , act-acted.

2.以不发音的''-e''结尾动词，动词词尾加''-d''，如：live-lived move-moved decide-decided hope-hoped judge-judged raise-raised 3.以辅音字母''+ y''结尾的动词，把''-y''变为''-i''再加''-ed''，如: study-studied try-tried copy-copied cry-cried carry-carried embody-embodied 4.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：stop-stopped beg-begged fret-fretted drag-dragged drop-dropped plan-planned 注:fix的过去式和过去分词x不双写，为fixed. 5.不规则动词的过去式变化规律性不强，须多加记忆。
