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：
