可数名词和不可数名词复数变化规则英语中的名词指的是一种抽象的或者具体的事物，它有可数和不可数之分。

所谓可数名词指的就是在数量上可以计数，可以数出数量的事物；所谓不可数名词是指不能以数目来计算，不可以分成个体的概念、状态、品质、感情或表示物质材料的东西。

一、可数名词在它之前可以加上冠词a/an（以元音字母a,e,i,o,u开头的字母前冠词用an)。

而不可数名词前面是不可以直接加冠词的。

可数名词复数变化规律如下：a. 一般情况下，直接加-s，如：book-books, bag-bags, cat-cats, bed-beds ；读音：清辅音后读[s]，浊辅音和元音后读[z]。

b．以s,x,ch,sh结尾，加-es，如：bus-buses, box-boxes, brush-brushes, watch-watches ；读音：[iz]。

c．以“辅音字母+y”结尾，变y为i, 再加-es，如：family-families, baby-babies 婴儿；读音：[z]。

以“元音字母+y”结尾，直接加-s，如：monkey-monkeys,toy-toys ; 读音：[s]。

d．以“f或fe”结尾，变f或fe为v, 再加-es，如：knife-knives, leaf---leaves树叶；读音：[z]。

e．以“o”结尾的词，分两种情况1）有生命的加-es 读音：[z] 如：mango-mangoes，tomato-tomatoes ，hero-heroes2)无生命的加-s 读音：[z] 如：photo-photos，radio-radiosf. 以ce,se,ze,de,ge结尾，加-s，如：exercise-exercises，读音：[z]。

g. 不规则名词：小老鼠爬灯台，偷油吃下不来。

男人当警察，保护妇女跟儿童；英国人的牙咬了法国人的脚；养了一头日本羊，送给了中国人；养了一头鹿跟鹅，卖给了瑞士人。

man-men, woman-women, policeman-policemen, policewoman-policewomen,goose---geese鹅，mouse(老鼠）-mice, child-children, foot-feet, tooth-teeth, ox-oxen(公牛）h. 除此之外，还有一部分名词单复数同形，如：fish鱼，deer鹿，sheep绵羊,news 新闻，goods 商品，fish，people 人，human人类i. 有一些名词则只有复数形式：trousers裤子，pants裤子，shorts短裤glasses眼镜，compasses圆规，scales天平，pliers钳子，clips剪子j. “某国人”的复数有三种类型：（1）Chinese, Japanese, Swiss 三国人单数复数同形，不需加s；（2）Englishman, Frenchman, Dutchman复数要把man 变为men；注意：German的复数是Germans,它的man不是词根，而是由Germany演变过来的。

（3）其他各国人以–an, -ian结尾的均直接加s。

如：Americans, Australians, Indians等。

可依照这个口诀记忆：中日瑞士均不变，英法荷兰都要变，其他”s”加后面。
