Question

动词变过去分词的时候什么样的词最后一个字母要双写

Answer 1

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：

Answer 2

重读闭音节，一个辅音字母结尾
即：1.元音字母非字母本音的音节重读
2.一个（不是两个、三个）辅音字母结尾
