单词+ed
①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
