把下列单词按划线部分的读音分类.played visited worked washed called wanted endedturned laughede opened mended/t/_________________/d/________________/Id/________________

/t/ worked washed laughed
/d/ played called turned opened
/Id/ visited wanted ended mended
规律如下：
1。 如果单词以/t/或者/d/ 结尾，词尾加ed读音需要加/Id/
2。 如果单词以清辅音（即声带不振动）结尾，例如/k/，/p/,/f/等，词尾加ed读音需要加/t/
3。 如果单词以浊辅音（即声带振动）结尾，例如/g/，/b/,/v/等，词尾加ed读音需要加/d/

/t/ worked washed laughed
/d/ played called turned opened
/Id/ visited wanted ended mended

played visited worked washed called wanted ended
turned laughede opened mended

答案：
/t/ : worked, washed, laughed
/d/ : played, called, turned, opened
/id/ : visited, wanted, ended, mended

解析：本题考察的是动词过去式,ed结尾的发音,在清辅音后面+ ed,发/t/ 的音,在元音或浊辅音结尾+ ed 发/d/ 的音,在t, d 后面+ed,发/id/的音.
