名詞
A)、名詞的數(shù)
我們知道名詞可以分為可數(shù)名詞和不可數(shù)名詞，而不可數(shù)名詞它沒有復(fù)數(shù)形式，但可數(shù)名詞卻有單數(shù)和復(fù)數(shù)之分，復(fù)數(shù)的構(gòu)成如下：
一)在后面加s。如：fathers, books, Americans, Germans, apples, bananas
二)x, sh, ch, s, tch后加es。如：boxes, glasses, dresses, watches, wishes, faxes
三)1)以輔音字母加y結(jié)尾的變y為i再加es 如：baby-babies, family-families, duty-duties, comedy-comedies,documentary-documentaries, story-stories
2)以元音字母加y結(jié)尾的直接加s。如：day-days,boy-boys, toy-toys, key-keys, ways
四)以o結(jié)尾加s(外來詞)。如：radios, photos, 但如是輔音加o的加es：如: tomatoes西紅柿, potatoes馬鈴薯
五)以f或fe結(jié)尾的變f為v再加es(s)。如：knife-knives, wife-wives, half-halves, shelf-shelves, leaf-leaves,yourself-yourselves
六)單復(fù)數(shù)相同(不變的)有：fish, sheep, deer鹿子, Chinese, Japanese
七)一般只有復(fù)數(shù)，沒有單數(shù)的有：people,pants, shorts, shoes, glasses, gloves, clothes, socks
八)單詞形式不變，既可以是單數(shù)也可以是復(fù)數(shù)的有：police警察局，警察, class班，同學(xué), family家，家庭成員
九)合成的復(fù)數(shù)一般只加主要名詞，多數(shù)為后一個單詞。如：ACTion movie-ACTion movies, pen pal-pen pals; 但如果是由man或woman所組成的合成詞的復(fù)數(shù)則同時為復(fù)數(shù)。如：man doctor-men doctors, woman teacher-women teachers
十)有的單復(fù)數(shù)意思不同。如：fish魚 fishes魚的種類, paper紙 papers報紙，卷子，論文, work工作 works作品，工廠, glass玻璃 glasses玻璃杯，眼鏡, orange桔子水 oranges橙子, light光線 lights燈, people人 peoples民族, time時間times時代, 次數(shù), chicken 雞肉 chickens 小雞
十一)單個字母的復(fù)數(shù)可以有兩種形式直接加s或’s。如：Is (I’s), Ks (K’s)。但如是縮略詞則只加s。如：IDs, VCDs, SARs
十二)特殊形式的有：child-children, man-men, woman-women, foot-feet, mouse-mice,policeman-policemen, Englishman-Englishmen
B)名詞的格
當(dāng)我們要表示某人的什么東西或人時，我們就要使用所有格形式。構(gòu)成如下：
一)單數(shù)在后面加’s。如：brother’s, Mike’s, teacher’s
二)復(fù)數(shù)以s結(jié)尾的直接在s后加’，如果不是以s結(jié)尾的與單數(shù)一樣處理。如：Teachers’ Day教師節(jié), classmates’; Children’s Day六一節(jié), Women’s Day婦女節(jié)
三)由and并列的名詞所有時，如果是共同所有同一人或物時，只加最后一個’s，但分別擁有時卻分別按單數(shù)形式處理。如：Mike and Ben’s room邁克和本的房間(共住一間)，Mike’s and Ben’s rooms邁克和本的房間(各自的房間)
