1个回答

1．一般情况下在原形后加-ed.如：work-worked,help-helped.2．以e结尾的单词,在原形后加-d.如：like-liked,joke-joked,hope-hoped.3.以"辅音字母+y"结尾的单词,变y为i再加-ed.如：study-studied,carry-carried,copy-copied.4．以重读闭音节、末尾只有一个辅音字母结尾的单词,双写末尾的辅音字母再加-ed.如：stop-stopped,prefer-preferred,admit-admitted,plan-planned.有些动词的过去式和过去分词有特殊的形式.cost-cost-cost meet-met- met catch-caught-caught rise-rose-risen drive-drove- driven get-got-got/gotten leave-left-left smell-smelt/smelled-smelt/smelled tell-told-told take-took-taken
