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。

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
