动词变过去分词的时候什么样的词最后一个字母要双写

动词过去式、过去分词变化规则

一、规则变化：

1.一般在动词原形后加-ed

look->looked;need->needed

2.以-e结尾的动词加-d

move->moved

3.以辅音字母加y结尾的动词，变y为i，再加-ed

carry->carried;study->studied

4.以元音字母加y结尾的词，直接加-ed

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

stop->stopped;regret->regretted

（但fix的过去式和过去分词x不双写，为fixed）

6.以-r音节结尾的词，双写r字母，再加-ed

refered->referred;prefer->preferred

二、对于不规则变化，也有些规律可循，下面归纳得不错：
