名词单数变复数变化规则：一．可数名词1．一般名词复数是在名词后面加上“s”，如map→maps，bag→bags，book-books 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，是不可数名词；2.fish 指“鱼的多少”时，是可数名词，但单数和复数同行；There are many fish in the river。

3.fish 强调鱼的“种类“时，复数是“fishes”。

There are many kinds of fishes in the river。

9. 有些名词以-s 结尾，但表达的是单数意义，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，要表达他们的量时常用pair，例如：a pair of glasses/shoes; 复数只需量词变复数，例如：two pairs of shoes11. 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，如果后面的名词是复数，则man，woman 也要跟着变复数。

如： a woman teacher - t hree 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 office2. 以-s 结尾的复数名词后加“'” 如：the teachers' s office3. 不以-s 结尾的名词复数后加“'s”，如：the Children's Palace4.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 我的一张照片名词单数变复数的练习题一、写出下列名词的复数形式1、orange ___________2、class ___________3、monkey __________4、piano ____________5、child ____________6、shelf ______________7、bed ____________8、country __________9、family ___________ 10、toy ____________ 11、foot __________ 12、radio ___________13、photo___________ 14、tomato ___________ 15、woman ____________ 16、knife ________17、sheep___________ 18、ship ___________ 19、dish____________ 20、mouse _____________二、用所给的单词的复数的正确形式填空：1> There are three _____________ (chair) in the classroom.2> These ____________ (tomato) are red.3> My brother looks after two ______________ (baby)4> My father likes to eat _____________ (potato).5> Chinese ______________ (people)like to eat noodles.6> I have a lot of ____________ (toy) in my bedroom.7> My mother wash ______________ (dish) in the kitchen. 8> I have two ____________ (pencil-box).9> There are some _______________ (bus)in the street. 10> Monster has eight _____________ (foot). 三、选择填空( )1．I can see three __________ in the zoo.
