2.、以s、x、ch、sh结尾的单词，在该词末尾加上-es；读音规则：读[iz]； eg：bus→buses; box→boxes; watch→watchches; dish→dishes

3、以辅音字母+y结尾的名词，要把y变为i，再加-es；读音规则：读[z]。 eg：fly→flies; baby→babies; 元音字母加y结尾的单词直接加s；eg：toy→toys；boy→boys；

4、以-f或-fe结尾的名词，要将-f或-fe变为-v，再加es；读音规则：读[vz]； eg：knife→knives；leaf→leaves；wife→wives

5、以-o结尾的名词，只有四个单词要加-es，其余都加-s；读音规则：读[z]。 eg：tomato→tomatoes西红柿; potato→potatoes土豆; hero→heroes英雄; Negro—Negroes黑人 口诀：“黑人英雄喜欢吃土豆和西红柿” 其余eg：zoo→zoos; photo→photos, radio→radios； 特殊名词变复数不规则变化：
