一,名词的数
我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:
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)以辅音字母加y 结尾的变y 为i 再加es 如:city-cities body-bodies factory-fctories, baby-babies, family-families, duty-duties, comedy-comedies, dstory-stories
2)以元音字母加y 结尾的直接加s 。如:day-days, boy-boys, toy-toys, key-keys, ways
四)以o 结尾加s (外来词)。如:radios, photos, 但如是辅音加o 的加es :如: tomatoes 西红柿, potatoes 马铃薯
五)以f 或fe 结尾的变f 为v 再加es(s)。如:knife-knives, wife-wives, half-halves, shelf-shelves,
leaf-leaves, yourself-yourselves
六)单复数相同(不变的)有:fish, sheep, deer 鹿子, Chinese, Japanese
七)一般只有复数,没有单数的有:people,pants, shorts, shoes, glasses, gloves, clothes, socks 八)单词形式不变,既可以是单数也可以是复数的有:police 警察局,警察, class 班,同学, family
家,家庭成员
九)合成的复数一般只加主要名词,多数为后一个单词。如:action movie-action movies, pen pal-
pen pals; 但如果是由man 或woman 所组成的合成词的复数则同时为复数。如:man doctor-men doctors, woman teacher-women teachers
十)有的单复数意思不同。如:fish 鱼 fishes 鱼的种类, paper 纸 papers 报纸,卷子,论文, work
工作 works 作品,工厂, glass 玻璃 glasses 玻璃杯,眼镜, orange 桔子水 oranges 橙子, light 光线 lights 灯, people 人 peoples 民族, time 时间 times 时代, 次数, chicken 鸡肉 chickens 小鸡十一) 单个字母的复数可以有两种形式直接加s 或’s 。如:Is (I ’s), Ks (K ’s)。但如是缩略词
则只加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
二,名词的格
当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:
一)单数在后面加’s 。如:brother ’s, Mike ’s, teacher ’s
二)复数以s 结尾的直接在s 后加’,如果不是以s 结尾的与单数一样处理。如:Teachers ’ Day
教师节, classmates ’; Children ’s Day 六一节, Women ’s Day 三八节
三)由and 并列的名词所有时,如果是共同所有同一人或物时,只加最后一个’s ,但分别拥有时
却分别按单数形式处理。如:Mike and Ben ’s room 迈克和本的房间(共住一间),Mike ’s and Ben ’s rooms 迈克和本的房间(各自的房间)
