第三篇:英語名詞單數(shù)變復(fù)數(shù)
英語中名詞可分為可數(shù)名詞和不可數(shù)名詞。可數(shù)名詞在應(yīng)用時(shí)有單數(shù)和復(fù)數(shù)形式,表示一個(gè)用單數(shù),表示兩個(gè)或兩個(gè)以上用復(fù)數(shù)。復(fù)數(shù)名詞的構(gòu)成分為規(guī)則變化和不規(guī)則變化。
一、名詞單數(shù)變復(fù)數(shù)的規(guī)則變化 1.一般在名詞詞尾加“-s” map—maps地圖bird—birds鳥
orange—oranges 桔子bike—bikes自行車 2.以s, x, ch, sh結(jié)尾的名詞加“-es” box—boxes盒子class—classes班級(jí)
watch—watches手表dish-dishes盤,碟子,餐具 3.以o結(jié)尾的無生命的名詞后面加“-s” photo—photos相片radio—radios收音機(jī) zoo—zoos動(dòng)物園
以o結(jié)尾的有生命的名詞后面加“-es”
tomato—tomatoes西紅柿potato—potatoes土豆 hero—heroes英雄negro—negroes黑人 4.以輔音字母加y結(jié)尾的名詞,變y為i加“-es” baby—babies嬰兒family—families家庭 以元音字母加y結(jié)尾的名詞直接加“-s” boy—boys男孩toy—toys 玩具
5.以fe或f結(jié)尾的名詞,把fe或f變?yōu)関加“-es” knife—knives小刀wife—wives妻子 leaf—leaves樹葉
二、名詞單數(shù)變復(fù)數(shù)的不規(guī)則變化
1.child—childrenfoot—feettooth—teeth mouse—miceman—menwoman—women 注意:與man和woman構(gòu)成的合成詞,其復(fù)數(shù)形式也是-men和-women,例如:anEnglishman—two Englishmen 但German不是合成詞,故復(fù)數(shù)形式為Germans;Bowman是姓,其復(fù)數(shù)是the Bowmans(鮑曼一家)。
2.單復(fù)數(shù)同形的名詞
例如:deer鹿,sheep綿羊,fish魚,Chinese中國(guó)人,Japanese日本人
注意:除人民幣元、角、分外,美元、英鎊、法郎等都有復(fù)數(shù)形式。例如: a dollar—two dollars 3.集體名詞,以單數(shù)形式出現(xiàn),但實(shí)為復(fù)數(shù)。
例如: people人,police警察,cattle牛等本身就是復(fù)數(shù),不能說 a people,a police,a cattle,但可以說 a person,a policeman,a head of cattle the English,the British,the French,the Chinese,the Japanese等名詞,表示國(guó)民總稱時(shí),作復(fù)數(shù)用,例如:
The Chinese are hard-working and brave.中國(guó)人民是勤勞勇敢的。
三、以s結(jié)尾,仍為單數(shù)的名詞 1.maths數(shù)學(xué),politics政治(學(xué)),physics物理學(xué)等學(xué)科名詞,為不可數(shù)名詞,是單數(shù)。
2.news消息、新聞,為不可數(shù)名詞。
3.the United States美國(guó),the United Nations聯(lián)合國(guó),應(yīng)視為單數(shù)。
The United Nations was organized in 1945.聯(lián)合國(guó)是1945年組建起來的。
4.以復(fù)數(shù)形式出現(xiàn)的書名,劇名,報(bào)紙,雜志名,也視為單數(shù)。“The Arabian Nights” is a very interesting story-book.<<一千零一夜>>是一本非常有趣的故事書。注意:
1.表示由兩部分構(gòu)成的東西,如:glasses(眼鏡)trousers,clothes若表達(dá)具體數(shù)目,要借助數(shù)量詞 pair(對(duì),雙);suit(套);a pair of glasses;two pairs of trousers 2.還有一些名詞,其復(fù)數(shù)形式有時(shí)可表示特別意思,如:goods貨物,waters水域,fishes(各種)魚
第四篇:英語單數(shù)變復(fù)數(shù)規(guī)則
英語名詞單數(shù)變復(fù)數(shù)的規(guī)則
一、絕大多數(shù)的可數(shù)名詞的復(fù)數(shù)形式,是在該詞末尾加上后輟-s。
讀音變化:結(jié)尾是清輔音讀[s],結(jié)尾是濁輔音或元音讀[z]。(輔音按發(fā)音時(shí)聲帶的振動(dòng)模式,可以分為清輔音和濁輔音兩大類。發(fā)音時(shí)聲帶不震動(dòng)、送氣的叫清輔音;發(fā)音時(shí)聲帶震動(dòng)、不送氣的叫濁輔音。)
例: cat→cats;sport→sports;friend→friends;style→styles;eye→eyes
二、凡是以s、z、x、ch、sh結(jié)尾的詞,在該詞末尾加上后輟-es構(gòu)成復(fù)數(shù)。讀音變化:統(tǒng)一加讀[iz]。
例:bus→buses;fox→foxes;match→matches;flash→flashes
三、輔音結(jié)尾的名詞
1.以輔音字母+y結(jié)尾的名詞,將y改變?yōu)閕,再加-es。讀音變化:加讀[z]。
例:candy→candies;daisy→daisies;fairy→fairies;lady→ladies;story→stories 2.以元音+y結(jié)尾的名詞,直接加s 例:boy→boys;monkey→monkeys;
四、以-o結(jié)尾的名詞
1.有生命的名詞+es(英雄、土豆、西紅柿、芒果就加-es)
例1:hero-heroes;tomato→tomatoes;potato→potatoes;mango→mangoes 2.無生命的名詞+s 例2:silo→silos;piano→pianos;photo→photos;macro→macros radio-radios
五、以-f或-fe結(jié)尾的名詞,多為將-f或-fe改變?yōu)?ves,但有例外。讀音變化:尾音[f]改讀[vz]。
例:knife→knives;life→lives;leaf→leaves;staff→staves;scarf→scarves
反例:roof→roofs
六、極少數(shù)單詞,其復(fù)數(shù)形式?jīng)]有任何規(guī)律。讀音變化:沒有規(guī)律。
例:man→men;woman→women;child→children;person→people;
ox→oxen;mouse→mice;foot→feet;tooth→teeth 注意:
1.部分單詞的單數(shù)、復(fù)數(shù)形式不變。讀音變化:保持原音。
例:fish→fish(當(dāng)fish表示不同種類的魚時(shí),可以加復(fù)數(shù)詞尾);sheep→sheep;
cattle→cattle;deer→deer;Chinese→Chinese
2.另一些名詞則以復(fù)數(shù)詞出現(xiàn)的機(jī)會(huì)較多
例:bellows風(fēng)箱;clothes衣物;shorts短褲;scissors剪刀;spectacles/glasses眼鏡;shears大剪刀;trousers長(zhǎng)褲;jeans牛仔褲;wages工資
