过去式的变化规则

【过去式的变化规则】

①一般情况下，在动词原形后直接加ed。

如：wanted，played。

②以不发音的字母e结尾的动词，直接加d。

如：hoped，lived。

③重读闭音节单词需双写最后一个辅音字母，再加ed。如：stopped, shipped。

④以辅音字母+y结尾的动词变y为i，再加ed。

如：studied，worried。

⑤有些动词不符合上面的规则，需要特殊记忆。

如：am(is)-was, are-were, go-went, eat-ate,

swim-swam, buy-bought, see-saw,

teach-taught, bring-brought, think-thought,

fall-fell, hurt-hurt, break-broke, win-won,
