单词+ed①单词加ed后的发音：ed后缀读音规则单词最后加了ed读音为，/d/，/t/，/id/，有一些简单的规则 ：记住“清清浊浊”所谓清清是指清辅音后面的ed也发清辅音——“/t/”比如。
worshipped tapped等等。所谓浊浊是指浊辅音和元音（即声带震动的音）后的ed发浊辅音——“/d/”比如。lived，opened等等另外，比较特别的是：“t”、“d”两个辅音结尾的单词后面ed是发“/id/”的音。
②动词加ed的规则（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
