一、名词变复数的规则变化：1、一般情况在后面加s，读音为清辅音后读/s/,浊辅音后读/z/，如：book--books,bed--beds2、以s,es,ch,sh 结尾的在后面加es，读音为/iz/，如：box--boxes,watch--watches.3、以ce,ze,se,(d)ge 结尾的在后面加s，读音为/iz/，如：orange--oranges,horse--horses.4、以辅音字母加y结尾的，先把y变成i，再加es，读音为/z/，如family--families,baby--babies.另外还有不规则地变化，如man--men,woman--women,child--children. 如果是动词变三单规则与名词变复数规则差不多，去掉第三条，第二条加上以o 结尾的加es,如go--goes,do--does二、写出下列名词单复数的形式。
