名词单数变复数变化规则

名词单数变复数变化规则:

一.可数名词

1.一般名词复数就是在名词后面加上“s”,如map→maps, bag→bags,book-books 等;

2.以s,x, sh, ch结尾的词加“es”,如bus→buses, watch→watches, box-boxes等;

3.以f或fe结尾的名词变复数时,去掉f, fe 加ves的名词有: half→halves knife→knives leaf→leaves wolf→wolves wife→wives life→lives thief→thieves

4.以o 结尾的名词变复数时:

a)加s的名词有(无生命):photo→photos ,piano→pianos, radio→radios

b)加es的名词有(有生命): potato→potatoes tomato→tomatoes

5.以辅音字母＋y结尾的词,变y为i加es,如baby→babies, family-families, study-studies等;

以元音字母＋y结尾的名词变复数时,直接加s变复数,如monkey→monkeys, holiday→holidays, storey→storeys(楼层);

6、oo变ee的单词:foot-feet, goose-geese, tooth-teeth;

7、a变e的单词: man-men, woman-women, policeman-policemen;

8、复数与原形一致的单词:fish-fish, sheep-sheep, deer-deer, Chinese-Chinese, Japanese-Japanese;

注:1、fish指“鱼肉”时,就是不可数名词;2、fish指“鱼的多少”时,就是可数名词,但单数与复数同行;There are many fish in the river。3、fish强调鱼的“种类“时,复数就是“fishes”。There are many kinds of fishes in the river。

9、有些名词以-s结尾,但表达的就是单数意义,例如:news,maths,politics,physics,the United States等。

10、常以复数形式出现的名词,例如:glasses,trousers,shoes,gloves,socks等,要表达她们的量时常用pair,例如:a pair of glasses/shoes; 复数只需量词变复数,例如:two pairs of shoes

11、名词作定语时,不用复数形式,如:a shoe shop。如果要表示复数,则去掉不定冠词,把名词词组中的最后一个名词变成复数形式,如:an apple tree---apple trees 例外:man,woman作定语时,如果后面的名词就是复数,则man,woman也要跟着变复数。如:a woman teacher----three women teachers

常见的不可数名词:

Food, meat, fish, chicken, beef, drink, milk, water, homework, news, information, fun, work, Chinese, English, music等

二.名词所有格

(一)表示有生命的名词所有格

1、在单数名词后加---’s,如:the teacher’ s office

2、以-s结尾的复数名词后加“’”如:the teachers’ s office

3、不以-s结尾的名词复数后加“’s”,如:the Children’s Palace

4、用and连接两个并列的单数名词表示共有时,只需在后一个并列名词词尾加“’s”;如果不就是,则需在各个并列名词后分别加“’s”。如:John and Mary’ s house, John’ s and Mary’ s house

(二)表示无生命的名词所有格

一般用“of +名词”表示,如:the capital of China

(三)双重所有格

将’s与of 结合一起使用构成双重所有格,

例如:

a friend of my father’s 我父亲的一位朋友

a photo of mine 我的一张照片
