常见动词过去式过去分词的变化规则

动词过去式和过去分词有规则变化和不规则变化两种。

一、规则变化:

1. 一般情况直接加ed，如ask—asked, work—worked

2. 以不发音的e结尾，只加d，如love—loved, dance—danced

3. 以辅音字母加y结尾，把y变为i，再加ed，如try—tried, study—studied

4. 以一个元音字母和一个辅音结尾的重读闭音节结尾的动词(以重读闭音节或r 音节结尾而末尾只有一个辅音字母),先双写末尾这个辅音字母,再加ed,如stop—stopped, permit—permitted 注：A. 以l结尾的动词,尾音节重读时,双写l,如control—controlled;尾音节不重读时,双不双写都可以，如travel—traveled(美) /travelled(英) 。

B. 特例:

picnic—picnicked—picnicked(去野餐),traffic—trafficked—trafficked（交易,在…通行）另外,还有很多动词的过去式和过去分词是不合乎上述规则的,需要熟记.(见后)

①.-ed在清辅音音素后发音为[t]: helped, liked, finished, fetched, stopped, clapped
