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→thieves4.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→radiosb)加es的名词有(有生命): potato→potatoes tomato→tomatoes5.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 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 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、A、monkeysB、monkeysC、monkey ( )2、The pig has four ________、A、footB、feetC、foots( )3、My two brothers are ________、A、policemanB、policemansC、policemen ( )4、I can see ten _____ in the picture、A、sheepB、dogC、pig( )5、The _____ has three_____、A、boys, watchesB、boy, watchC、boy, watches ( )6、Can you see _______on the plate?A、breadB、breadsC、breades ( )7、The girl often brushes her_____ before she goes to bed、A、toothB、toothsC、teeth ( )8、Mr、Black often drink some _________、A、milkB、milksC、milkes ( )9、There are some _____on the floor、A、childB、manC、books ( )10、Lucy will has some _______、A、photoB、photosC、photoes ( )11、I am drinking two ________、A、cups of waterB、cup of waterC、cups of water s ( )12、The cat eats two _______ on Monday、A、mousesB、miceC、mouse( )13、I need a pen and some _____、A、booksB、deskC、chair( )14、There are______ in the room、A、photosB、photoesC、photo( )15、There is some _____ in the river、A、fishB、fishesC、fishs( )16、There___ two ___in the box、A、is watchB、are watchesC、are watch( )17、We have to clean ___ every day、A.our tooth B、our tooths C、our teeth( )18、My _____ room is next to the reading room、A、teacherB、teacher’sC、teachers( )19、Tom and Jim are ______、A、friendsB、friendC、brother( )20、How many _____do they have?A、pictureB、picturesC、a picture四写出下列名词的复数形式。
