---动词变化规律

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。

go - went make - made get - got buy - bought come - came fly-flew
