动词加ed的规则口诀

一般直接加，“哑e”去e加，“重闭”双写加，“辅y”改i加。一般直接加，即在动词后直接加ed；以不发音的字母e结尾的动词直接加d（或去掉不发音的e,再加ed）；重读闭音节（必须是一个短元音加一个辅音字母）结尾的动词，要先双写结尾的辅音字母，再加ed；以辅音字母加y结尾的动词，先将y改为i再加ed。

（1）一般情况下,动词词尾加ed,如：worked played wanted acted

（2）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

（3）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

（4）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
