一般情况下,动词词尾加 -ed ,如: worked played wanted acted 以不发音的 -e 结尾动词,动词词尾加 -d,如: lived moved decided declined hoped judged raised wiped 以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如: studied tried copied justified cried carried embodied emptied 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: stopped begged fretted dragged dropped planned dotted dripped 注:不规则动词的过去式变化规律性不强,须多加记忆。 go - went make - made get - got buy - bought come - came fly-flew
规则动词一般在动词后+ed,如played。不发音e结尾+d,如moved,以辅音字母+y结尾的动词,把-y变为-i 再加-ed,如studied。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 stopped。
不规则动词也有一些不明显的规律,但是需要在阅读中记忆,以下列举几个:
