规则动词的过去式词尾变化有几种
1．一般情况下加ed，如watched, planted, watered, pulled, climbed, picked。
2．以不发音字母e结尾的加d，如liked, moved, tasted。
3．以辅音字母加y结尾的变y为i再加ed，如study——studied。
4．以1个元音字母加1个辅音字母结尾的重读闭音节，
双写最后一个辅音字母再加ed，如stop——stopped。
词尾读音有3种：
a．在浊辅音和元音后读[d]，如lived, watered, listened, played。
b．在清辅音后读[t]，如liked, helped, watched。
c．在[t],[d]音后读[Id]，如planted, wanted, handed(上交)。
