第一篇:英语名词单数变复数的若干规则

英语名词单数变复数的若干规则

1.名词复数的规则变化

(1)一般情况加词尾-s,如 book / books, desk / desks等。(2)以 s, x, z, sh, ch 等结尾的名词,通常加词尾-es:bus / buses, box / boxes, dish / dishes等。(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 ies;以“元音字母+y”结尾的名词,直接加词尾-s:city / cities, toy / toys, holiday / holidays 等。2.复数规则变化的几点说明

(1)以 ch 结尾的名词变复数时加词尾-es,指的是 ch 读音为[tF]时;若ch的读音为[k],则其复数应加词尾-s,如 stomach[tstQmEk]是 stomachs,而不是 stomaches。(2)以y结尾的专有名词,直接加词尾s变复数。如: There are two Marys in our class.我们班在两个玛丽。

(3)以 o 结尾的名词,有些加词尾-s,有些加-es,但在中学英语范围内,以o结尾的名词变复数加词尾-es 的主要有以下4个:tomato(西红柿),potato(土豆),hero(英雄),Negro(黑人)。

注:有些以o 结尾的名词在变复数时加-s或-es均可,如zero / zero(e)s(零)等。(4)以 f 或 fe 结尾的名词,也有两种可能:即有些直接加词尾-s,有些则把 f / fe 改为 ves:roof / roofs(屋顶),knife / knives(小刀)等。但在中学英语范围内,要改 f / fe 为 ves 的只有以下10个词(它们都是日常生活中的常用词):wife(妻子),life(生命),knife(小刀),leaf(树叶),thief(贼),half(一半),self(自己),shelf(架子),loaf(面包),wolf(狼)。注:中学英语中的handkerchief(手帕)在变复数时有两种形式:handkerchiefs / handkerchieves,但在现代英语中,以用 handkerchiefs 为多见。3.单数与复数同形的名词 这类名词不多,主要的有: sheep 绵羊

fish 鱼

deer 鹿 Chinese 中国人

Japanese 日本人 Portuguese 葡萄牙人 Swiss 瑞士人 aircraft 飞行器 means 方法 series 系列

head(牛等的)头数 works 工厂

注:(1)fish 有时也用 fishes 这样的复数形式,尤其是表示种类时;head 若不是表示牲口的“头数”,而是表示“人的头”或“人数”,则要用 heads 这样的复数形式。

(2)由汉语拼音形式出现的名词,其复数与单数同形,如 fifty yuan(5元),thirty fen(3角),five li(5里),ten mu(10亩)等。4.名词复数的不规则变化

有的名词单数变复数时,没有一定的规则,需特别记忆: man / men 男人

woman / women 女人 child / children 小孩 tooth / teeth 牙齿 foot / feet 脚

goose / geese 鹅 mouse / mice 老鼠 ox / oxen 公牛 注:(1)一些以 man, woman 结尾的合成词,在构成复数时与 man, woman 的变化形式相同,如:policeman / policemen(警察),Englishman / Englishmen(英国人),等等。但是 human(人),German(德国人),Walkman(随身听)不是合成词,它们的复数要按一般规则变化,即为 humans, Germans, Walkmans,而不是 humen, Germen, Walkmen。又如Bowman是姓,其复数是Bowmans,不是 Bowmen。

(2)foot表示“英尺”时,其复数可以有两种形式 feet / foot,如:He is about six feet [foot] tall.他大约6英尺高。

5.复合名词变复数的方法

复合名词变复数通常是将其主要名词变为复数:

passer-by / passers-by 过路人 looker-on / lookers-on 旁观者 若没有主要名词,则通常在最后一个词尾加s: know-all / know-alls 万事通

对于由man / woman用于另一名词前构成的合成名词,则需将两者变为复数: man nurse / nurse doctors 男护士

woman lawyer / women lawyers 女律师

英语语法---比较级和最高级的用法

在英语中通常用下列方式表示的词:在形容词或副词前加more(如 more natural,more clearly)或加后缀-er(newer,sooner)。典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中,将比较两个主体的方法叫做“比较句型”。其中,像“A比B更„„”的表达方式称为比较级;而“A最„„”的表达方式则称为最高级。组成句子的方式是将形容词或副词变化成比较级或最高级的形态。

一、形容词、副词的比较级和最高级的构成规则

1.一般单音节词和少数以-er,-ow结尾的双音节词,比较级在后面加-er,最高级在后面加-est;

(1)单音节词

如:small→smaller→smallest short→shorter→shortest

tall→taller→tallest great→greater→greatest

(2)双音节词

如:clever→cleverer→cleverest narrow→narrower→narrowest

2.以不发音e结尾的单音节词,比较在原级后加-r,最高级在原级后加-st;

如:large→larger→largest nice→nicer→nicest able→abler→ablest

3.在重读闭音节(即:辅音+元音+辅音)中,先双写末尾的辅音字母,比较级加-er,最高级加-est;

如:big→bigger→biggest hot→hotter→hottest fat→fatter→fattest

4.以“辅音字母+y”结尾的双音节词,把y改为i,比较级加-er,最高级加-est;

如:easy→easier→easiest heavy→heavier→heaviest

busy→busier→busiest happy→happier→happiest

5.其他双音节词和多音节词,比较级在前面加more,最高级在前面加most;

如:beautiful→more beautiful→most beautiful

different→more different→most different

easily→more easily→most easily

注意:(1)形容词最高级前通常必须用定冠词 the,副词最高级前可不用。

例句: The Sahara is the biggest desert in the world.(2)形容词most前面没有the,不表示最高级的含义,只表示“非常”。

It is a most important problem.=It is a very important problem.6.有少数形容词、副词的比较级和最高级是不规则的,必须熟记。

如:good→better→best well→better→best

bad→worse→worst ill→worse→worst

old→older/elder→oldest/eldest

many/much→more→most little→less→least

far →further/farther→ furthest/farthest

二、形容词、副词的比较级和最高级的用法

1.“A + be +形容词比较级 + than + B” 意思为“A比B更„„”。

如:This tree is taller than that one.这棵树比那棵树高。

注意:

① 在含有连词than的比较级中,前后的比较对象必须是同一范畴,即同类事物之间的比较。

②在比较级前面使用much,表示程度程度“强得多”。

如:A watermelon is much bigger than an apple.③ very, quite一般只能修饰原级,不能修饰比较级。

2.“比较级 + and + 比较级”或“more and more +原级”表示“越来越„„”

如:It becomes warmer and warmer when spring comes.春天来了,天气变得越来越暖和了。

It is getting cooler and cooler.天气越来越凉爽。

The wind became more and more heavily.风变得越来越大。

Our school is becoming more and more beautiful.我们的学校变得越来越美丽。

3.在含有or的选择疑问句中,如果有两者供选择,前面的形容词要用比较级形式。

如:Who is taller,Tim or Tom? 谁更高,Tim还是Tom?

4.“the +比较级„„, the+比较级”,表示“越„„越„„”。

The more money you make, the more you spend.钱你赚得越多,花得越多。

The sooner,the better.越快越好。

5.表示倍数的比较级用法:

①.A is „times the size /height/length/width of B.如:The new building is three times the height of the old one.这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高)

②.A is „times as big /high/long/wide/large as B.如:Asia is four times as large as Europe.亚洲是欧洲的四倍大。(亚洲比欧洲大三倍)

③.A is „times larger /higher/longer/wider than B.如:Our school is twice bigger than yours.我们学校比你们学校大两倍。

6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较,表示“最„„”的意思。

句子中有表示范围的词或短语。如:of the three, in our class等等。

如:He is the tallest in our class.他在我们班里是最高的。

7.“否定词语+比较级”,“否定词语+ so„ as”结构表示最高级含义。

Nothing is so easy as this.=Nothing is easier than this.=This is the easiest thing.8.比较级与最高级的转换:

Mike is the most intelligent in his class.Mike is more intelligent than any other student in his class

7.修饰比较级和最高级的词

1)可修饰比较级的词

①.a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。

②.还可以用表示倍数的词或度量名词作修饰语。

③.以上词(除by far)外,必须置于比较级形容词或副词的前面。

注意: 使用最高级要注意将主语包括在比较范围内。

(错)Tom is the tallest of his three brothers.(对)Tom is the tallest of the three brothers.2)下列词可修饰最高级:by far, far, much, mostly, almost。

This hat is nearly / almost the biggest.注意:

a.very可修饰最高级,但位置与much不同。

This is the very best.This is much the best.b.序数词通常只修饰最高级。

Africa is the second largest continent.8.要避免重复使用比较级。

(错)He is more cleverer than his brother.(对)He is more clever than his brother.(对)He is cleverer than his brother.9.要避免将主语含在比较对象中。

(错)China is larger that any country in Asia.(对)China is larger than any other country in Asia.10.要注意对应句型,遵循前后一致的原则。

The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out.11.要注意冠词的使用,后有名词的时候,前面才有可能有名词。

比较:Which is larger, Canada or Australia?

Which is the larger country, Canada or Australia?

She is taller than her two sisters.She is the taller of the two sisters.三.典型例题

1)----Are you feeling ____?

----Yes,I'm fine now.A.any well B.any better C.quite good

D.quite better

答案:B.any 可修饰比较级,quite修饰原级,well的比较级为better.2)The experiment was____ easier than we had expected.A.more B.much more C.much

D.more much

答案:C.much可修饰比较级,因此B,C都说得通,但easier本身已是比较级,不需more,因此C为正确答案。

3)If there were no examinations, we should have ___ at school.A.the happiest time B.a more happier time

C.much happiest time D.a much happier time

答案:D。

比较级和最高级的用法

1.两者相比(甲=乙),用“as+原级+as”表示 Tom is as tall as Mike.2.两者相比(甲〈 乙),用“not as(so)+原级+as”或“less than”表示 I didn’t do my homework so(as)carefully as you.The picture is less attractive than that one.3.两者相比(甲〉乙),用“比较级+than”表示

Our city is more beautiful than any other city in our country.注意:1)为了避免重复,在从句中常用one, that, those等词来代替前面提过的名词。

The weather here is warmer than that of Shanghai.The radios made in our factory are better than those in your factory.2)比较等级应注意避免和包括自己的对象比。比较级+than+

any other + 单数名词 all the other + 复数名词 anyone else

any of the other + 复数名词

3)如果形容词作定语修饰一个单数可数名词,一般将不定冠词a/an放在形容词之后。

Our neighbour has _____ ours.A.as a big house as

B.as big a house as C.the same big house as D.house the same big as

4)比较级前一般不用冠词,但若表示“两者中较„„时”。比较级前要加定冠词。若比较级后有名词,常在比较级前加不定冠词,表示泛指。E.g.他是两者中较高的一个 He is the taller of the two.她唱得真动听!我可从未听过比这更好的嗓音了。

How beautifully she sings!I have never heard a better voice.4.三者或三者以上相比,表示最高级时,用“the +最高级”的结构表示,这种句式一般常有表示比较范围的介词短语。Zhang Hua is the tallest of the three.He works(the)hardest in his class.That was the least exciting football game I’ve ever watched.This hotel is the most comfortable I’ve ever stayed.注意:当最高级的前面无限定词the或有不定冠词a/an时,仅表示“很„„,非常„„”

Monday is my busiest day.星期一是我很忙的一天。

Qingdao is a most(very)beautiful coastal city.青岛是一个非常美丽的海滨城市。

比较级的一些其他用法 倍数表示方法

a)

倍数+as+形容词/副词原级+ as b)

倍数+形容词/副词比较级+than c)

倍数+ the + n.+ of

This rope is three times longer than that one.(这条绳子比那条长三倍。)This rope is three times as long as that one.(这条绳子是那条绳子的三倍。)

This rope is three times the length of that one.(这条绳子比那条绳子长三倍。)2 用形容词比较级的否定形式,从反面来表示最高级,通常译为“没有比„„更„„”

No other book has a greater effect on my life.没有哪一本书比这本书对我的影响更大的了。=This book has the greatest effect on my life.考例: —Go for a picnic this weekend, OK?

--_____.I love getting close to nature.A.I couldn’t agree more

B.I’m afraid not.C.I believe not

D.I don’t think so.3 more and more 越来越„ „ Our city is getting bigger and bigger.Our city is getting more and more beautiful.4 the more „ the more „

越„ „就越„ „ The more you study, the more you know.The busier the old man is, the happier he feels.The more intelligent students are, the more quickly they understand ideas.可用下列词来修饰形容词的比较级

much a lot slightly a little almost far a bit still

第二篇: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

1.child—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 1.maths数学,politics政治(学),physics物理学等学科名词,为不可数名词,是单数。

2.news消息、新闻,为不可数名词。

3.the 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。

4.以复数形式出现的书名,剧名,报纸,杂志名,也视为单数。“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。注意:

1.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 2.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

例:man→men;woman→women;child→children;person→people;ox→oxen 十三、一些单数词得加en才能变成复数词: 例:ox→oxen;child→children;brother→brethren 十四、一些单数词得改头换面一番,才能变成复数词

二十一、除人民币元、角、分外,美元、英镑、法郎等都有复数形式。例:a dollar, two dollars;a meter, two meters 以O结尾的词,许多加es构成复数,特别是一些常用词如:heroes,potatoes,tomatoes,echoes,tornadoes,torpedoes,dominoes,vetoes,mosquitoes,Negroes,mangoes,buffaloes,volcanoes

但下面几类词只加s:1.以“元音+o”或“oo”结尾的词如:videos,radios,studios,folios,oratorios,embryos,zoos,bamboos,kangaroos,taboos

2.一些外来词,特别是音乐方面的词,如:pianos,solos,concertos,tobaccos,mottos,cellos 3.一些缩写词和专有名词,如:kilos,photos,memos,micros,Eskimos,Filipnos 有个别词加两种词尾都可以,如:archipelago(e)s,halo(e)s,cargoes(英),cargos(美)
