规则动词的过去式变化如下：
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
注：不规则动词的过去式变化规律性不强，须多加记忆。
