动词过去分词变化规则与不规则变化

动词过去分词变化规则与不规则变化（一）变化规则：与过去式规则一样。

1.一般直接在词尾加上ed。look---looked----looked

2.以e结尾的动词，直接加d。move---moved----moved

3.以y结尾，y前面是辅音字母的动词，变y为i，再加ed。carry---carried-----carried

4.部分动词需双写尾字母，加ed。stop----stopped----stopped

（二）不规则变化：

不规则动词的变化因词而异。但如对不规则动词的过去式和过去分词做一分析，就可发现其中的“规则”。为方便同学们记忆，现将部分不规则动词的原形、过去式和过去分词列出并规为五种类型。以便准确记忆。
