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-brushes

2、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)—leaves

3、口诀：辅音+ y 在词尾，把y 变i 再加-es；

study-studies; baby-babies; city-cities

4、口诀：元音+y在词尾, 只加s就足够

boy –boys ; day –days; monkey –monkeys

5、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-pianos

6、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 docto—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; sheep

this---these(这些)I --- we 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。

②tooth(牙齿)—teeth,foot(脚)—feet,goose（鹅）—geese

③child(孩子)—children(孩子们) ④mouse(老鼠)—mice, louse(虱子)—lice

⑤sheep(绵羊)—sheep,deer(鹿)—deer, fish(鱼)—fish

（三）“某国人”复数

口诀：中日不变，英法变，其余s加后面。

【说明】

①“中日不变”指：Chinese（中国人），Japanese（日本人）的复数是其本身。

②“英法变”指：英国人和法国人的复数须把a改为e.有：Frenchman（法国男人）—Frenchmen Frenchwoman（法国女人）—Frenchwomen

Englishman（英国男人）—Englishmen

Englishwoman（英国女人）—Englishwomen

③“其余-s加后面”指：除了上面几个词外须加s. 如：German(德国人)—Germans

American(美国人)—Americans

二、不可数名词

不可数名词一般没有复数形式，不能与a/an或表示具体数量的词直接连用。这些名词前往往加some(一些)，any(任何，一些),no(没有),a little(少许)等词。

常见的不可数名词有：

饮料类：water,milk,orange,tea,coffee,juice

食物类：food,bread,cheese,rice,soup

肉类：meat,pork,fish,beef,duck,chicken,

其它：news（新闻、消息）,information（信息）,work（工作）,weather（天气）,homework（家庭作业）,money （钱）,time（时间）等。

不可数名词量的表达：“数词+名词+of+不可数名词”。需要注意的是，如果数词大于1时，量词要变为复数形式，不可数名词不能加s.如：

four bottles of orange/milk 四瓶桔汁/牛奶

five glasses of water 五杯水

nine bowls of rice 九碗米饭

a cup of tea 一杯茶
