文档介绍：英语动词的过去式及过去分词 
规则动词的过去式和过去分词变化非常简单,即
一般情况下,动词词尾加-ed ,如: 
work ---worked play---played wanted----wanted act----acted 
2、以不发音的-e 结尾动词,动词词尾加-d,如: 
live---lived move----moved taste---tasted hope---hoped 
3、以辅音字母+ y结尾的动词,把-y变为-i 再加-ed,如: 
study---studied copy---copied cry---cried carry---carried 
4、以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加-ed,如: 
stop ---stopped 
不规则动词的过去式变化规律性不强,须多加记忆,经常思考反复整理发现其实也是有些规律的,如下:
1. A---A---A型(现在式、过去式和过去分词同形)
cost 花费
cut割,切
hit 打
let让
put放下
read 读(读法不一样)
hurt 伤
2. A---A---B型(现在式和过去式同形)
beat beat beaten 打
3. A---B---A型(现在式和过去分词同形)
come e 来
e became e 变
run ran run 跑
4. A ---B ---B型
在动词原形后加一个辅音字母d或t构成过去式或过去分词。

learn learned/learnt learned/learnt 学习
mean meant meant 意思是
hear heard heard 听见
把动词原形的最后一个辅音字母“d”改为“t”构成过去式或过去分词。
