五种变化规则
动词的`过去式和过去分词的变化规则有五种，详细如下：
1、一般在动词原形后加-ed。
例：look；looked；looked；call；called；called
注意：-ed在清辅音音素后 发音为[t]，在浊辅音后发音为[d]，在元音后发音也为[d]，-ed在[t]、[d]后发音为[id] needed[ni:did].
2、以-e结尾的动词直接加-d。
例：move；moved；moved；phone；phoned；phoned
3、以辅音字母加y结尾的动词，变y为i，再加-ed。
例：study；studied；studied
4、以元音字母加y结尾的词，直接加-ed。
例：play；played；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。
例：stop；stopped；stopped

规则动词过去分词构成规则：
(1)一般动词，在词尾直接加“-ed”。（然而要注意的是，过去分词并不是过去式）
work——worked——worked,visit——visited——visited.
(2)以不发音的“e”结尾的动词，只在词尾加“d”。
live——lived——lived.

过去式和过去分词区别：
过去分词表的'意义是被动或完成。而过去式和过去分词最主要的'区别是：过去式是一个动词，而过去分词是一个动词的非谓语形式，相当于一个形容词或副词
1、过去式是一个动词，单独作谓语。不能与助动词、情态动词连用。它的词性与动词的第三人称单数一样。
2、过去分词是动词的一种非谓语形式，也叫非限定性动词。
