以不发音的e结尾的动词后面加d。

以“辅音字母+y”结尾的动词，变y为i，再加-ed。词尾只有一个辅音字母的重读闭音节动词，要双写辅音字母，再加-ed。不规则变化：5.以不变应万变。如：let→let→let;put→put→put;read→read→read6.若中间有双写e，则去掉一个e，单词末尾再加t。如：feel→felt→felt;keep→kept→kept;sleep→slept→slept7.结尾的字母d变t。如：lend→lent→lent;build→built→built;send→sent→sent8.变为以-ought或-aught结尾。如：buy→bought→bought;bring→brought→brought;catch→caught→caught;teach→taught→taught活学活用1.Writetheformsofthepasttenseandpastparticiple:drink____________see____________find____________leave____________tell____________drankdrunksawseenfoundfoundleftlefttoldtold
