大家好，我是sweet老师，可数名词的复数形式多种多样，究竟应该选择哪一个呢？这些例子为大家总结了用法，涵盖了小学阶大部分单词，希望能对大家有所帮助。
1、可数名词有单数、复数之分，
名词复数形式的构成规则：
(1) 一般在名词词尾加“s”
如：teacher—teachers egg---eggs
(2) 以s, x, sh, ch结尾的名词加es
如class---classes box-- boxes bus --buses watch--watches
(3) 以辅音字母+y 的名词变y为i再加es
如：story---stories library---libraries,
dictionary----dictionaries hobby---hobbies
(4) 以f, fe 结尾的名词，变f, fe为v加es
如：life ---lives leaf ---leaves half---halves
knife---knives wolf-wolves wife---wives
(5) 以o结尾的名词“英雄芒果土豆西红柿”加es
hero---heroes mango--- mangoes
potato--- potatoes tomato--- tomatoes
其余加s（目前所学的词） zoo---zoos kilo---kilos
radio—radios photo--- photos piano-- pianos
(6)不规则名词单复数形式
如： child — children woman --- women
man ---men foot---feet tooth---teeth
有的可数名词单、复数形式相同，如 Japanese，Chinese，sheep,
如： I have one sheep. He has two sheep.
2、不可数名词没有复数形式
不可数名词有：(1)milk, water, juice, tea, ice;
(2) food, rice, meat, fish, chicken, bread, cheese
(3) paper, newspaper , hair, time, money, homework, housework
不可数名词的数量常表示如下
