动词过去式和过去分词有规则变化和不规则变化两种
一、规则变化
1、一般在动词原形后加-ed
call-called open-opened need-needed
发音规则:
1、-ed在清辅音音素后 发音为t在浊辅音后发音为d在元音后发音也为d
2、-ed在t、d 后发音为id
注意但fix的过去式和过去 分词x不双写,为fixed.
2、以-e结尾的动词加-d
phone-phoned hope-hoped agree-agreed
3、以辅音字母加y结尾的动词,变y为i, 再加-ed
studied -studied carried-carried try-tried
4、以原音字母加y结尾的词,直接加-ed
enjoy-enjoyed stay-stayed play-played
5、末尾只有一个辅音字母的重读闭音节词,双写该辅音字母,再加-ed
plan-planned fit-fitted stop-stopped
6、以-r音节结尾的词,双写r字母,再加-ed
