以不發(fā)音的e結(jié)尾的動(dòng)詞后面加d。

以“輔音字母+y”結(jié)尾的動(dòng)詞，變y為i，再加-ed。詞尾只有一個(gè)輔音字母的重讀閉音節(jié)動(dòng)詞，要雙寫(xiě)輔音字母，再加-ed。不規(guī)則變化：5.以不變應(yīng)萬(wàn)變。如：let→let→let;put→put→put;read→read→read6.若中間有雙寫(xiě)e，則去掉一個(gè)e，單詞末尾再加t。如：feel→felt→felt;keep→kept→kept;sleep→slept→slept7.結(jié)尾的字母d變t。如：lend→lent→lent;build→built→built;send→sent→sent8.變?yōu)橐?ought或-aught結(jié)尾。如：buy→bought→bought;bring→brought→brought;catch→caught→caught;teach→taught→taught2、表過(guò)去發(fā)生的某一動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果。例如：Ihavejustcleanedmyclothes.我剛洗過(guò)衣服。（“洗衣服”是發(fā)生在過(guò)去的動(dòng)作，對(duì)現(xiàn)在造成的結(jié)果是“衣服干凈了”）Ihavejusthadmybreakfast.(對(duì)現(xiàn)在的影響：不餓)--HaveyoureadLittleWomenyet?--No,Ihaven’t.(我對(duì)該書(shū)不了解）3、通常與表示包括現(xiàn)在在內(nèi)的時(shí)間副詞just（剛剛）,already（已經(jīng)）,before,yet（一般疑問(wèn)：已經(jīng)；否定句：還）never,ever等狀語(yǔ)連用。
