2.Weformthesimplepasttensebyadding‘-ed’toregularverbs.1绝大多数动词+edwalk—walked2以e结尾的动词+dlive—lived3以辅音字母+y结尾的动词变y为iedcry—cried4以一个元音字母+一个辅音字母结尾的短动词双写末尾的辅音字母+edstop—stopped

提示:以元音字母+y结尾的动词按第一条规则，即：+ed,如:stay—stayedplay--played

want—talk—like—worry—try—stop—wantedtalkedlikedworriedtriedstopped写出下列动词的过去式。

规则动词-ed的读音1、清念/t/，即ed在清辅音后面念/t/,例：finishedhelpedpassedcooked2、元浊/d/,即ed在元音，浊辅音后面念/d/,例：borrowedenjoyedcalledmoved3、/t//d/之后念/id/,即ed在/t//d/音后面念/id/例：wantedshoutedneededcounted

3.不规则动词的过去式不是加ed构成的,需要我们记住它们。不规则动词的过去式归纳起来有这样几种类型(见下表)：
