英语名词变复数的规则及练习题

1.名词

名词可以分为专有名词和普通名词，专有名词是某个（些）人，地方，机构等专有的名称，如Beijing，China等。普通名词是一类人或东西或是一个抽象概念的名词，如：book，sadness等。普通名词又可分为下面四类：

1）个体名词：表示某类人或东西中的个体，如：gun。

2）集体名词：表示若干个个体组成的集合体，如：family。

3）物质名词：表示无法分为个体的实物，如：air。

4）抽象名词：表示动作、状态、品质、感情等抽象概念，如：work。

个体名词和集体名词可以用数目来计算，称为可数名词，物质名词和抽象名词一般无法用数目计算，称为不可数名词。

1.1 名词复数的规则变化

情况

构成方法 读音 例词

一般情况 加-s 清辅音后读/s/ map-maps

浊辅音和元音后读 /z/ bag-bags /car-cars

以s, sh, ch, x等结尾 加-es 读 /iz/ bus-buses/ watch-watches

以ce, se, ze,等结尾 加-s 读 /iz/ license-licenses 以辅音字母+y结尾 变y 为i再加es 读 /z/ baby---babies

1.2 其它名词复数的规则变化

1）以y结尾的专有名词，或元音字母+y 结尾的名词变复数时，直接加s变复数。例如：

two Marys

the Henrys

monkey---monkeys

holiday---holidays

2）以o 结尾的名词，变复数时：

a.加s，如： photo---photos

piano---pianos

radio---radios

zoo---zoos；

b.加es，如：potato--potatoes

tomato--tomatoes

c.上述a和b两种方法均可，如zero---zeros / zeroes。

3）以f或fe 结尾的名词变复数时：

a.加s，如： belief---beliefs

roof---roofs

safe---safes

gulf---gulfs；

b.去f,fe 加ves，如：half---halves

knife---knives leaf---leaves

wolf---wolves

wife---wives

life---lives

thief---thieves；

c.上述a和b两种方法均可，如handkerchief: handkerchiefs /

handkerchieves。

1.3 名词复数的不规则变化

1）child---children

foot---feet

tooth---teeth

mouse---mice

man---men

woman---women

注意：由一个词加 man 或 woman构成的合成词，其复数形式也

是-men 和-women，如an Englishman，two Englishmen。但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans。

2）单复同形，如deer，sheep，fish，Chinese，Japanese，li，jin，yuan，two li，three mu，four jin等。但除人民币的元、角、分外，美元、英镑、法郎等都有复数形式。如：a dollar, two

dollars;a meter, two meters。

3）集体名词，以单数形式出现，但实为复数。例如：

people police cattle 等本身就是复数，不能说 a people，a

police，a cattle，但可以说a person，a policeman，a head of

cattle, the English，the British，the French，the Chinese，the

Japanese，the Swiss 等名词，表示国民总称时，作复数用，如The

Chinese are industries and brave.中国人民是勤劳勇敢的。

4）以s结尾，仍为单数的名词，如：

，politics，physics等学科名词，一般是不可数名词，为单数。

为不可数名词。

United States，the United Nations 应视为单数。

The United Nations was organized in 1945.联合国是1945年组建起来的。

d.以复数形式出现的书名，剧名，报纸，杂志名，也可视为单数。例如：

“The Arabian Nights” is a very interesting story-book.《一千零一夜》是一本非常有趣的故事书。

5）表示由两部分构成的东西，如：glasses（眼镜）trousers,

clothes等，若表达具体数目，要借助数量词 pair（对，双）;suit（套）;a pair of glasses;two pairs of trousers等。

6）另外还有一些名词，其复数形式有时可表示特别意思，如：goods货物，waters水域，fishes（各种）鱼。

1.4 不可数名词量的表示

1）物质名词

a.当物质名词转化为个体名词时为可数。

比较：Cake is a kind of food.蛋糕是一种食物。（不可数）

These cakes are sweet.这些蛋糕很好吃。（可数）

b.当物质名词表示该物质的种类时，可数。例如：

This factory produces steel.（不可数）

We need various steels.（可数）

c.当物质名词表示份数时，可数。例如：

Our country is famous for tea.我国因茶叶而闻名。

Two teas, please.请来两杯茶。

2）抽象名词表示具体的事例时也可数。例如：

four freedoms 四大自由

the four modernizations四个现代化

物质名词和抽象名词可以借助单位词表一定的数量，如a glass of

water 一杯水/ a piece of advice 一则建议。

5.定语名词的复数

名词作定语一般用单数，但也有以下例外。

1)

用复数作定语。例如：

sports meeting 运动会

students reading-room 学生阅览室

talks table 谈判桌

the foreign languages department 外语系

2）man, woman, gentleman等作定语时，其单复数以所修饰的名词的单复数而定。例如：

men workers

women teachers

gentlemen officials

3）有些原有s结尾的名词，作定语时，s保留。例如：

goods train（货车）

arms produce 武器生产

customs papers 海关文件

clothes brush

衣刷

4）数词+名词作定语时，这个名词一般保留单数形式。例如：

two-dozen eggs 两打鸡蛋

a ten-mile walk 十英里路

two-hundred trees 两百棵树

a five-year plan.一个五年计划

1.6 不同国籍人的单复数

国籍

总称（谓语用复数）单数 复数

中国人 the Chinese a Chinese

two Chinese

瑞士人 the Swiss a Swiss two Swiss

澳大利亚人

the Australians

an Australian two Australians

俄国人 the Russians a Russian two Russians

意大利人 the Italians an Italian two Italians

希腊人 the Greek a Greek two Greeks

法国人 the French a Frenchman two Frenchmen

日本人

the Japanese a Japanese two Japanese

美国人

the Americans an American two Americans

印度人 the Indians an Indian two Indians

加拿大人 the Canadians a Canadian two Canadians

德国人 the Germans a Germans two Germans

英国人 the English an Englishman two Englishmen

瑞典人 the Swedish a Swede two Swedes

1.7 名词的格

英语中有些名词可以加“'s”来表示所有关系，带这种词尾的名词形式称为该名词的所有格，如：a teacher's book。名词所有格的规则如下：

1）单数名词词尾加“'s”，复数名词词尾没有s，也要加“'s”，如the boy's bag 男孩的书包，men's room 男厕所。

2）若名词已有复数词尾-s，只加“ ' ”，如：the workers'

struggle 工人的斗争。

3）凡不能加“'s”的名词，都可以用“名词+of +名词”的结构来表示所有关系，如：the title of the song 歌的名字。

4）在表示店铺或教堂的名字或某人的家时，名词所有格的后面常常不出现它所修饰的名词，如：the barber's 理发店。

5）如果两个名词并列，并且分别有's，则表示“分别有”；只有一个's，则表示'共有'。例如：

John's and Mary's rooms（两间）

John and Mary's room（一间）

6）复合名词或短语，'s 加在最后一个词的词尾。例如：a month

or two's absence

第四篇：英语名词变复数口诀

可数名词的复数变化规律[1]：

名词复数有规律，一般词尾加s;辅音字母+y型，变y为i,es;

ch,sh真有趣，s,x,es;f,fe真小气，字母v来把它替，es在后别忘记；

字母o来真神奇，番茄土豆英雄来es,钢琴照片收音机+s.番茄(tomato)土豆(potato)英雄(hero)钢琴(piano)照片(photo)收音机(radio)

可数名词复数特殊变化规律[2]：

中日好友来聚会，绵羊、鹿、鱼把家回。

男士、女士a变e；

牙（齿）、脚双o变双e;

孩子们想去天安门，原形后面r、e、n;

老鼠本来爱大米，mice,ice和rice.注：中Chinese,日Japanese，好友people.绵羊sheep,鹿deer,鱼fish（这些单词单复数一样）

man--men woman—women tooth--teeth foot—feet child--children mouse--mice 记住f（e）结尾的名词复数

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

九个以-f(e)结尾的名词。wife（妻子）、knife（刀子）、wolf（狼）、thief（小偷）、shelf（架子）、self（自己）、life（生命）、half（一半）、leaf（树叶）

这些名词以-f(e)结尾变复数时，将-f(e)变v再加es。还有以-self结尾的反身代词复数用法也同样，如: lf-yourselves.例外的有serf（农奴）、chief（首领）、belief（信仰）、safe（保险柜）、gulf（海湾），它们以直接加-s变为复数形式，另外handkerchief可用两种复数形式。handkerchiefs或handkerchieves.

第五篇：英语名词单数变复数

英语中名词可分为可数名词和不可数名词。可数名词在应用时有单数和复数形式，表示一个用单数，表示两个或两个以上用复数。复数名词的构成分为规则变化和不规则变化。

一、名词单数变复数的规则变化 1.一般在名词词尾加“-s”

map—maps地图bird—birds鸟

orange—oranges 桔子bike—bikes自行车 2.以s, x, ch, sh结尾的名词加“-es” box—boxes盒子class—classes班级

watch—watches手表dish-dishes盘，碟子，餐具 3.以o结尾的无生命的名词后面加“-s” photo—photos相片radio—radios收音机 zoo—zoos动物园

以o结尾的有生命的名词后面加“-es”

tomato—tomatoes西红柿potato—potatoes土豆 hero—heroes英雄negro—negroes黑人 4.以辅音字母加y结尾的名词，变y为i加“-es” baby—babies婴儿family—families家庭 以元音字母加y结尾的名词直接加“-s” boy—boys男孩toy—toys 玩具

5.以fe或f结尾的名词，把fe或f变为v加“-es” knife—knives小刀wife—wives妻子 leaf—leaves树叶

二、名词单数变复数的不规则变化

—childrenfoot—feettooth—teeth mouse—miceman—menwoman—women 注意：与man和woman构成的

合成词，其复数形式也是-men和-women，例如：anEnglishman—two Englishmen 但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans（鲍曼一家）。

2.单复数同形的名词

例如：deer鹿，sheep绵羊，fish鱼，Chinese中国人，Japanese日本人

注意：除人民币元、角、分外，美元、英镑、法郎等都有复数形式。例如: a dollar—two dollars 3.集体名词，以单数形式出现，但实为复数。

例如： people人，police警察，cattle牛等本身就是复数，不能说 a people，a police，a cattle，但可以说 a person，a policeman，a head of cattle the English，the British，the French，the

Chinese，the Japanese等名词，表示国民总称时，作复数用，例如：

The Chinese are hard-working and brave.中国人民是勤劳勇敢的。

三、以s结尾，仍为单数的名词 数学，politics政治（学），physics物理学等学科名词，为不可数名词，是单数。

消息、新闻，为不可数名词。

United States美国，the United Nations联合国，应视为单数。

The United Nations was organized in 1945.联合国是1945年组建起来的。
