2.名词单数变复数的用法 篇二

1.名词复数的构成方法

规则变化的复数名词遵循以下原则:(1)在一般情况下,加词尾-s:

desk→desks 书桌 tree→trees 树 face→faces 脸

(2)以 s, x, sh, ch 等结尾的名词,通常加词尾-es: bus→buses 公共汽车 box→boxes 盒子 dish→dishes 盘子 peach →peaches桃子

(3)以y 结尾的名词,其复数构成要分两种情况:以“辅音字母+y”结尾的名词,将 y 改为 i+s;以“元音字母+y”结尾的名词,直接加词尾-s:

city→cities 城市 boy→boys 男孩 key→keys 钥匙 family→families

(4)以o结尾的名词,一般词尾-s,(除了四个单词-es tomato(西红柿),potato(土豆),hero(英雄),Negro(黑人)。piano→pianos 钢琴 tomato→tomatoes 西红柿

(5)以 f 或 fe 结尾的名词,一般将 f / fe 改为 ves: knife→knives 小刀 thief→thieves 贼 life→lives 生命

【注】初中英语中这类名词主要的有wife(妻子),life(生命),knife(小刀),leaf(树叶),thief(贼),half(一半),self(自己),loaf(面包),wolf(狼)。它们的复数形式均是将词尾的f或fe改为ves。另外,也有的以 f 或 fe 结尾的名词直接加词尾-s构成复数(如roof →roofs 屋顶),但这在初中英语中很少见。

2.单数与复数同形的名词

初中英语中主要的有: sheep 绵羊 fish 鱼 deer 鹿 Chinese 中国人

Japanese 日本人 Swiss 瑞士人 等

3.不规则的复数名词

有的名词单数变复数时,没有一定的规则:

man→men 男人 woman→women 女人 child→children 小孩

tooth→teeth 牙齿 foot→feet 脚 mouse→mice 老鼠 goose→ geese鹅

【注】一些以 man, woman 结尾的合成词,构成复数时与 man, woman 的变化形式相同,如:

policeman→policemen 警察 Englishwoman→Englishwomen(女)英国人

另外,当man和woman用于名词前作定语时,若其后被修饰的名词为复数,则man和woman也要用复数:

3.有趣的名词变复数小口诀 篇三

1.以O结尾的名词顺口

规律:有生命的以o结尾的名词变复数时,词尾加es,凡无生命的以o结尾的名词变复数时,词尾加s。

口诀1:黑人和英雄吃土豆和西红柿要加es

其余全部加s 解释:negroes and heroes eat tomatoes and potatoes 口诀2:你在“zoo”里

看见一根“bamboo”

上面挂着一张“photo”

所照的是一架“piano”

上面放着一台“radio”

解释:zoo-zoos, bamboo-bamboos, photo-photos piano-pianos, radio-radios.2.表示民族的名词顺口溜

口诀:“中、日、瑞”友好是一致;

“英、法”联盟a变e;

其他一律加s。

解释: Chinese,Japanese单复数同形;

Englishman,Frenchman的复数为Englishmen,Frenchmen; 其他像German,American,Australian等的复数形式是在后面加“s”。

3.以f、fe结尾的顺口溜

规律:以f(e)结尾的名词变为复数时,改“f(e)”为“ve”再加“s”。

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。解释:

wife(妻子),knife(刀子),wolf(狼)

thief(小偷),shelf(架子),life(生命)4.巧记不规则名词单变复

口诀:大鹅老鼠齐步走

男男女女龇龇牙 解释:goose-geese;mouse-mice;foot-feet;man-men;woman-women;tooth-teeth;5.单复数形式一致的顺口溜

4.主谓一致和复数名词时谓语单复数 篇四

*不定代词/疑问代词(something/anything/anywhere/somewhere/where/when)+单数

语法一致原则:句子谓语动词的数取决于该句子主语的数。

1。“the+姓氏名词的复数形式”(---的成员)+复数

2。all/some/half/enough/two thirds +名词(单/复数)+单/复数

3.复数形式的名词:clothes/trousers/shorts(短裤)/glasses/scissors/gloves/chopsticks等+复数

计量单位(pair)+ 复数形式的名词+谓语取决于 计量单位

意义一致原则:谓语动词的单、复数形式,取决于主语所表达的概念。

1.集体名词:people/public(公共)/police/crew(船员)+复数

2。复数形式,单数意义。(news/physics/maths/politics)

3.集合名词:class/family/team/Chinese/Japanese强调总体--单数;强调个体--复数。The class has 45 students.The class are planting trees on the hill.4.时间、距离、价格、重量的复数名词/算式+单数

Ten days is a long time.5.the +形容词“表一类人”+复数;

The rich have much money.6.and/both---and + 复数

7。one of/each of/none of/either of/neither of +名词+单数

8.a number(许多)+n +复数;the number(---的数量)+n +单数

9。名词+and+名词“表同一人/物用单数”“表不同人/物用复数”

The writer and the speaker are from the USA.The writer and speaker is from the USA.就近一致原则:谓语动词的数要与它紧邻的名词/代词的数保持一致。

1.or/not---but/either---or---/neither---nor---/not only---but also---+就近原则

2.There be+并列主语

(一)主谓一致的种类

1.语法形式上的一致

主语为单数形式,谓语动词用单数形式;主语为复数形式,谓语动词也用复数形式。如:

The number of the students present is 200.Jane and Mary look alike.2.意义上一致

1)主语形式虽为单数,但意义为复数,谓语动词用复数。如:The crowd were shouting.单数形式代表复数内容的词有:people, police, cattle等。

2)主语形式为复数,而意义上却是单数,谓语动词用单数。如:The news was so surprising.形复意单的单词有news和一些以ics结尾的学科名称,如physics,politics, economics等。

3.就近原则

即谓语动词的单、复数形式取决于最靠近它的词语。如用连词or,either…or, neither…not, not only…but also等连接的并列主语,如果一个是单数,一个是复数,谓语动词与靠近它的主语一致。如:

Either your students or Mr.Wang knows this.(二)主谓一致的应用

1.名词作主语

1)某些集体名词,如family, team等作主语时,如果作为一个整体看待,谓语动词用单数形式,如果就其中一个个成员而言,谓语动词用复数形式。如:

His family is a happy one.The whole family are watching TV.这类名词有:audience,class,club,company,crew,enemy,crowd,government,group,party,public,team等。

名词population一词的使用情况类似。“a group(crowd)of +复数名词”等短语之后的谓语动词也同样可用单数或复数,前者强调整体,后者强调各个部分。

2)某些集体名词,如people, police, cattle等,只当复数看待,谓语动词必须用复数。如:

The police are searching for the thief.3)单、复数同形的名词主语时,谓语动词应根据意义决定单、复数。如:

A sheep is over there.Some sheep are over there.4)名词所有格之后的名词被省略,这种情况一般只指商店、工厂、住宅等,作主语时,动词一般用单数。如:

The doctor’s is across the street.My uncle’s is not far from here.常见的省略名词有:the baker’s, the barber’s, the carpenter’s, the Zhang’s等。

表示店铺的名词,一般作集体名词看待,但用作主语时,谓语动词往往用复数。如:

Richardson’s have a lot of goods to sell.5)当名词词组中心词为表示度量、距离、金额、时间、书名等复数名词时,往往可以根据意义一致的原则,把这些复数名词看作一个整体,谓语用单数形式。如:

Three years has passed since then.6)不定代词each, every, no所修饰的名词即使以and或逗号连接成多主语时,谓语动词仍用单数形式。如:

Each boy and each girl wants to go to the cinema.7)如果主语有more than one…或many a…构成,尽管从意义上看是复数内容,但它的谓语动词仍用单数形式。如:

More than one student has read the book.Many a girl has been there.但是,“more +复数名词+than one”结构之后,谓语动词一般多用复数形式。如:

More members than one are against your plan.8)一些有两个部分构成的名词表示衣物或工具作主语时,谓语动词通常用复数形式,例如:glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。但如果主语用“a kind of, a pair of , a series of等加名词”构成时,谓语动词一般用单数形式。如:

A pair of shoes was on the desk.9)this kind of book =a book of this kind(这种书),其谓语动词用单数;短语this kind of men =men of this kind =these kind of men(口语)(这一类人),但this kind of men的谓语动词用单数,men of this kind和these kind of men的谓语动词用复数,all kinds of后跟复数名词,谓语动词用复数形式。如:

This kind of men is dangerous.Men of this kind are dangerous.10)复数形式的单、复数同形名词作主语时,按意义一致原则,作用单数意义时,谓语用单数,反之,谓语用复数。这类名词有:means(方法),works(工厂),species(种类),Chinese,Japanese等。如:

The(This)glass works was set up in 1980.(这家玻璃厂建于1980年。)

The(These)glass works are near the railway station.(这些玻璃厂在火车站附近。)

当它们前面有a, such a , this, that修饰时,谓语用单数;有all, such, these, those修饰时,谓语用复数,但means, no means, the means等词前没有以上修饰词时,可用作单数,也可用作复数。

11)如果名词词组中心词是all,most, half, rest等词语,所指的复数意义,谓语动词用复数形式;反之,用单数。如:

All of my classmates like music.All of the water is gone.12)在主谓倒装的句子中,谓语动词的数应与其后的主语一致。如:

Between the two windows hangs a picture.2.由连接词连接的名词作主语

1)

用and或both…and连接并列主语,谓语动词通常用复数形式。如:

Plastics and rubber never rot.Walking and riding are good exercises.但是,并列主语如果指的是同一个人、同一事物或同一概念时,谓语动词用单数形式,这时and后面的名词没有冠词。如: Truth and honesty is the best policy.The girl’s teacher and friend is a young doctor.To love and to be loved is great happiness.Going to bed early and getting up early is a good habit.A knife and fork is on the table.2)当主语后面跟有as well as, as much as, no less than, along with, with, like, rather than, together with, but, except, besides, including, in addition to等引导的词组时,其谓语动词的单、复数而定。如:

The teacher as well as the students was reading in the library.3)以or, either…or, neither…nor, not only…but also等连接的名词(代词)作主语时,谓语动词的单复数应根据就近一致的原则。如:

Tom or his brothers are waiting in the room.Either you or he is to go.3.代词作主语

1)名词性物主代词作主语时,既可以用作单数,也可以用作复数,这取决于它所代替的是单数还是复数。如:

Ours(Our Party)is a great party.Your shoes are black, and mine(=my shoes)are brown.2)such, the same起指示代词作用时,应根据其所指的内容来决定单、复数。如:

Such is our plan.Such are his words.3)关系代词who, that, which等在定语从句中作主语时,其谓语动词的数应与句中先行词的数一致。如:

Those who want to go please put up your hands.Some of the energy that is used by man comes from the sun.4)疑问代词who, what, which作主语时,谓语动词可根据说话人所要表达的意思决定单、复数。如:

Who lives next door ? It is Xiao Liu.Who live next door ? It is Zhang and Liu.What produce(s)heat ?

5)不定代词any, either, neither, none, all some, more等作主语时,有以下两种情况:

单独作主语时,视其在文中的意义,动词用单数或复数形式,例如:

Now all has been changed.All are present.either, neither单独作主语时,谓语通常用单数。

但后接of时,若of的宾语为不可数名词,动词当然用单数形式,若of的宾语为复数名词或代词时,动词可以是单数,也可以是复数,在正式文体中,单数形式的动词更常用。如:

Do(es)any of you know his address ?

None of them has(have)seen the film.4.分数、量词作主语

1)“分数或百分数+名词”构成的短语以及由“a lot of, lots of plenty of, a large quantity of, a heap of, heaps of, half of +名词”构成的短语作主语时,其谓语动词要与短语中of后面的名词的数保持一致,这是因为短语中后面的名词是中心词,而短语中前面的量词是修饰语,例如:

Lots of damage was caused by fire.About three-fourths of the earth’s surface is covered with water.Three-fifths of the workers here are women.和这种情况类似的还有“a number of+名词复数”,但是,“the number of +名词”的中心词却是number, 试比较:

A number of students have gone home.The number of pages in this book is two hundred.注意:(large)quantities of修饰可数或不可数名词,其短语作主语时,谓语动词一般用复数,例如:

Quantities of food(nuts)were on the table.短语in quantity, in large quantities意为“大量”;in small quantities意为“少量”。

2)a great deal of , a large amount of修饰不可数名词,其短语作主语时,谓语动词通常用单数;large amounts of修饰不可数名词,其短语作主语时,谓语动词通常用复数,例如:

A large amount of(A great deal of)damage was done in a very short time.Large amounts of money were spent on the bridge.3)表示数量的one and a half后,名词要用复数形式,但是其短语作主语时,谓语动词用单数形式,例如:

One and a half bananas is left on the table.4)half of,(a)part of修饰可数名词单数及不可数名词时,谓语动词用单数,修饰可数名词复数时,谓语动词用复数。

5.名词化的形容词作主语

如果主语由“the+形容词(或过去分词)”结构担任时,谓语通常用复数,这类词有:the brave, the poor, the rich, the blind, the young, the old, the sick, the dead, the deaf and dumb, the oppressed, the injured, the wounded, the unemployed等;但也有少数的过去分词与定冠词连用时指个别,则用单数。如:

The blind study in special schools.The departed was a well-known engineer.这类形容词或分词如果要表示个体时,就要与名词man, person或表示人的单数连和,如:an old man, a rich person, the(a)wounded soldier

6.从句作主语

1)由what引导的主语从句,谓语动词通常用单数,但所指的具体内容是复数意义时,谓语动词一般用复数形式,例如:

What we need is more time.What we need are doctors.2)在“one of+复数名词++who/that/which”引导的从句结构中,关系代词who/that/which的先行词是靠近它的复数名词而不是one,因此,从句中的动词应该是复数形式。如:

5.decide的名词复数 篇五

以-O结尾的名词名词变复数,有时加-s,有时加-es。(1)基本上有生命的词加-es: hero 英雄 tomato 西红柿 potato 马铃薯 Negro 黑人 echo 回声 torpedo 鱼雷 veto 否决权

(2)无生命的词加-s:

radio收音机 photo 照片 piano钢琴 solo 独唱,独奏曲 cello 大提琴 memo 备忘录 kilo 千克,公里 coo 咕咕声 taboo 禁止,禁忌 bingo 宾戈游戏 oratorio 清唱剧,宗教剧 zoo 动物园 Eskimo爱斯基摩人 Filipino 菲律宾人 micro 微米 hippo 河马 kangaroo 袋鼠 bamboo 竹子

(3)加-s /-es均可的词: zero 零 volcano 火山 archipelago 群岛 halo 光环,荣光 cargo 货物 tobacco 烟草 tornado 龙卷风,大雷 domino 多米诺骨牌 mosquito 蚊子 mango 芒果 buffalo 水牛 motto 座右铭,格言

当然还有一些词汇没有总结到,平日里我们也可以参照一下几个规则来变: 基本上有生命的词加es,无生命的加s,词末为两个元音字母的加s,一些外来词汇加s。

Negro hero likes to eat tomato and potato.此句中的negro,hero,tomato,potato变复数时,都要加“es”。

6.decide的名词复数 篇六

不可数名词 集体名词 不规则名词单复数

【不可数名词】

1、最常见的不可数名词有:advice, baggage, change(零钱), furniture, hair, homework, information, knowledge, luggage, money, news, progress, traffic

2、其它不可数名词还有:absence, age, anger, courage, energy, equipment, experience, failure, fear, food, fun, health, ice, industry, kindness, labour, luck, marriage, music, nature, paper, peace, pleasure, power, pride, rain, research, respect, safety, salt, sand, silence, sleep, strength, snow, technology, time, trade, transport, travel, trust, truth, waste, water, wealth, weather, wind, work(工作)

【集合名词】

有些集合名词,ommittee,council,crew,crowd,family,gang,government,group,mob,staff,team, union等,在意义上是复数,但在语法形式上是单数,这类名词作主语的主谓一致问题往往遵循“语法一致”或“意义一致”原则。

例如:

The committee has/have decided to dismiss him.A council of elders governs the tribe.The present government is trying to control inflation.The school staff are expected to supervise school meals.(一)通常作复数的集体名词

包括police,people, cattle, militia, vermin等,这些集体名词通常用作复数。例如:

The British police have only very limited powers.The militia were called out to guard the borderland.It seems the cattle on the sides of the dikes were the only living creatures in these desolate surroundings.(二)通常作不可数名词的集体名词

通常作不可数名词的集体名词,包括poultry,foliage,machinery, equipment,furniture, merchandise等,这类名词后的动词用单数形式。例如:

Poultry is expensive at this time of year.That green foliage was restful.The merchandise has arrived undamaged.All the machinery in the factory is made in China.The suite of furniture he bought was of contemporary style.The equipment of the photographic studio was expensive.(三)可作单数也可作复数的集体名词

可作单数也可作复数的集体名词,包括audience, committee, crew, family, government,jury等。

例如:

The audience was/were enthusiastic on the opening night of the play.The committee has/have decided to dismiss him.The jury is/are about to announce the winners.The government has/have discussed the matter for a long time.【不规则名词】

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:与 man 和 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 但除人民币元、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。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 pers on,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: a.maths,politics,physics等学科名词,为不可数名词,是单数。b.news 是不可数名词。c.the 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。The Arabian Nights is a very interesting story-book.>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 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

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 【双写】 在不特殊的情况下,当原形最后一个音节为重读闭音节时,需要双写。比如:swim——swimming run——running put——putting begin——begging 想不起来都是双写的.不一定都只有一个元音字母

【规律】

7.复数名词读音有规则 篇七

曾 文:Miss Huang, 上七年级以来,我们学了不少复数名词,它们的变化规则我们都很熟悉了,可它们的读音有规律吗?

Miss Huang: 当然有。哦,我这里正好有个可数名词复数形式的课件。请先看展示:

1. lamps, cakes, months 2. animals, flags, planes; bananas, brothers, eyes, knees, radios

3. aunts, dates; cards, friends 4. boxes, glasses, oranges 5. leaf -leaves, wife - wives

李诗慧:哦,看得出来,第1组中的s都发/s/,第2组发/z/,第3组/ts/或/dz/,第4组/Iz/,第5组/vz/。

Miss Huang: 下面我来总结一下:以清辅音结尾的单数可数名词变复数名词后,词尾所加的-s读/s/;若单数名词以浊辅音或元音结尾,那词尾所加的-s,-es就读/z/;如果单数名词是以/t/或/d/结尾,变复数名词在词尾加-s或-es之后,就要与/t/、/d/一起读作/ts/或/dz/;若单数名词词尾是以/s/, /z/, //, /t/, /d/这五个辅音音素结尾,变复数后所加的-s,-es就读/Ιz/;我们知道,以-f或-fe结尾的单数名词变为复数名词时,常将-f或-fe变为-ves,其中的-ves就读/vz/。

霍远强: 可是,这些都是规则变化的复数名词的读音规律,如果是不规则的该怎么办呢?

8.小学英语语法-名词复数 篇八

一、名词分可数名词和不可数名词。

1、可数名词(可数),如:book ,dog ,apple ,school 等。可数名词有复数。如: books ,dogs ,apples ,schools.2、不可数名词(不可数),如:water ,milk , meat等。不可数名词没有复数,通常通过量词来修饰。如:a cup of water ,a bottleof milk ,a plate of meat.这里我们重点说可数名词的复数。

二、可数名词的复数。

1.一般情况下,结尾直接加-s,如:book-books, bag-bags, cat-cats, bed-beds。

2.以s.x.sh.ch结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches ,match-matches

3.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries.4.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-kniveswolf-wolvesleaf-leaveslife-livesthief-thieves

5.不规则可数名词的复数。

9.名词变复数的规律是什么 篇九

一个名词如果表示一个或一样东西,它取单数形式,如pen,dog,tree,fact,church,kiss.如果表示两个或更多的这类东西,则需要用名词复数形式,如pens,dogs,trees,facts,churches,kisses.构成名词复数,大多数在单数形式后加-s或-es,有下面5种情况:

1.直接加-s.

如: tree-trees树, desk-desks桌 card-cards卡片, parent-parents;

2.以s、sh、ch、x结尾加es

如:bus-buses, box-boxes, watch-watches 手表, brush-brushes 刷子, glass-glasses.

3.以辅音字母+ y结尾的,改y为i再加es.

如:country-countries 国家、乡村, city-cities 城市, baby-babies, family-families,

特例:boy-boys, monkey-monkeys, toy-toys, play-plays(剧本)

4.以f或者fe 结尾的词,改f为v,再加es.
