标题: 动词变过去式的规则
表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下：　　（1）一般情况下，动词词尾加 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； decline—declined； hope—hoped；　（3）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 　　（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：　　stopped begged fretted dragged dropped planned dotted dripped 　　（5）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 ，is/am-was，are-were ，see-saw ，bring-brought，do-did，teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent, eat-ate,give-gave,sit-sat,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew, 　　put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam，sweep—swept，sing—sang，draw—drew，　　以上的（1）至（4）条中的发音均有改变，具体分别有/d/ /t/ /id/。　而不规则动词的过去式的发音则略有不同，但是有些还是按照一定规律变化的。如以上的：make - made，get - got ，buy - bought ，come - came ，fly-flew ，bring-brought，teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent,give-gave,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam，sweep—swept，sing—sang，draw—drew。
