初一英语名词单数变复数用法口诀及练习测试一、可数名词的复数形式(一)规则变化1、口诀：名词单数变复数，直接加-s 占多数；book-books; pen-pens; apple-apples※s, x, z, ch, sh 来结尾，直接加上-es；bus—buses,box—boxes,watch—watches,dish—dishes. dress-dresses; buzz-buzzes; watch-watches; brush-brushes2、词尾是f 或fe，去掉f或fe再加上ves；口诀：妻子持刀去宰狼，小偷吓得发了慌；躲在架后保己命，半片树叶遮目光。
①wife(妻子)—wives,knife(小刀)—knives,wolf(狼)—wolves(妻子”拿着“小刀”杀了“狼”)②thief(小偷)—thieves③shelf(架子)—shelves,self(自己)—selves,life(性命)—lives④half(一半)—halves,leaf(树叶)—leaves3、口诀：辅音+ y 在词尾，把y 变i 再加-es；study-studies; baby-babies; city-cities4、口诀：元音+y在词尾, 只加s就足够boy –boys ; day –days; monkey –monkeys5、口诀：词尾字母若是o，常用三个已足够，要加-es 请记好，hero, tomato, potato。
美国黑人和英雄爱吃土豆和西红柿。
negro-negroes; hero-heroes; potato-potatoes; tomato-tomatoes其余o结尾的词加s, photo-photos; piano-pianos6、口诀：复合名词变复数，一般后面一个变复数，但是碰到man,woman复合词，两个都要变复数。
如：grown-up—grown-ups (成年人)man doctor—men doctors (男医生)(二) 不规则变化男人女人a 变e，鹅足牙oo 变ee；man-men; woman-women; goose-geese; foot-feet; tooth-teeth老鼠虱子也好记，ous 变ic；mouse-mice; louse-lice孩子加上ren，鱼鹿绵羊不用变child-children; fish; deer; sheepthis---these(这些)I --- we it/he/she--- they that -- those(那些)【说明】①man（男人）—men,woman（女人）—women,含有man,woman的合成词，其复数是把a变成e.如：policewoman, postman, f isherman等。
