七年级可数名词单、复数练习（附加：名词单数面复数规则）
一、可数名词与不可数名词的区别
普通名词所表示的人或事物是可以按个数计算的，这类名词叫可数名词。
可数名词分为个体名词(表示某类人或事物中的个体，如
worker, farmer,desk, factory等)
集体名词(表示作为一个整体来看的一群人或一些事物，如
people, family等)。
如果普通名词所表示的事物是不能按个数来计算的，这类名词就叫不可数名词。
不可数名词分为
物质名词(表示无法分为个体的物质，如meat, rice, water, milk, orange等)
抽象名词(表示动作、状态、情况、品质等抽象概念，如
work, homework,time, health, friendship等)。
二、关于可数名词
可数名词有单数和复数两种形式。指一个人或一件事物时，用单数形式；指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下：
1.一般的名词词尾直接加-s 。如：
book → books room→ rooms
house → housesday → days
2.以s, ss, ch, sh, x 结尾的名词，在词尾加-es。但是有些以o结尾的外来词或缩写词的复数形式只加s,另外如果字母o前面是元音字母也只加s。
piano-->pianos(外来词，fromItalian)
photo-->photos(fromgreece)
bamboo-->bamboos(结尾的o前面是元音字母o）
cameo-->cameos（元音字母e）
bus→busesglass → glasses
watch →watches
dish→ dishes box → boxes
3.以"辅音字母+y"结尾的名词，要先将y改为i再加-es。如：
city →cities body →bodies
factory →factories等等。
boy→boys
play→plays
4.以f 或fe 结尾的名词，要将f或fe改为v再加-es。如：
half →halvesleaf → leaves
knife →knives wife →wives
5.特例，特例常常考，要记住。
①child → children
②man → men woman → women
policeman → policemen
(规律：man →men)
③tomato → tomatoes
potato → potatoes
注意： 初中英语以o结尾的名词变复数时只有这两个词加-es，其余的当然加-s喽！如：photo → photos ]以O结尾的单词变复数时，有生命的加es,无生命的加s.
如：photo,zoo,为无生命的，＋s
tomato,potato为有生命的，＋es.
④foot → feet tooth →teeth
注意：oo变成ee。]
⑤sheep, Chinese, Japanese单、复数同形
注意：变复数时词形不变。]
⑥people单数形式表示复数意义，要求谓语动词用复数； people的复数形式peoples通常指“多个民族”。
6.集体名词：表示一群人或物的名词叫集体名词。为便于弄清其特点，我们不妨把它们分为表示无生命的物的“类”和表示主要是由人构成的“群”的集体名词。
⑴表示“类”的集体名词，常见的有
Clothing、furniture、baggage/luggage、jewelry、traffic、information、machinery、merchandise、produce、scenery
①形式上总是单数，没有复数形式，作主语时，谓语用单数。The old machinery is out ofdate.
②不可直接与a（n）或数词连用。表数量时用much，little，some，a piece of，an article of等：Eachroom has five pieces of furniture.
③若需用代词，用单数代词：Do you want to see my jewelry?It is in thebox.
⑵表示“群”的集体名词常见的有
1.People、police、cattle、poultry、vermin、clergy、militia、crew；
以上的单词做主语时，谓语动词用复数：Thepolice are looking for him
2.amily、class、team、government、crowd、committee、jury、party、firm、couple、board、group、gang、enemy、union、audience、public、mankind、humanity、youth
以上的词把若集体当作一个整体时，用作单数；若考虑构成这些集体的各个成员时，看作复数。
My family is alarge one.我的家庭是个大家庭
My family are allworkers.我家里人都是工人
注意：把一个集体名词看作单数或复数，要注意前后一致。如：
The team isfamous for its(不能用their) longhistory.该对以历史悠久而闻名。
三、关于不可数名词
1.不可数名词没有复数，当它作句子的主语时，谓语动词要用单数形式。
如：The food isvery fresh. 食品很新鲜。
2.有的不可数名词也可以作可数名词，有复数形式，但他们的意义往往发生变化。
如：water (水) →waters (水域)
orange (橘汁) → oranges (橘子)
people（人）→peoples（民族）
3.很多不可数名词表示泛指时为不可数，表示种类时就可数，但意义大多不发生变化。
如：fruit →fruitsfood → foods
fish → fisheshair → hairs
四、名词可数不可数“六注意”
1、可数名词是可以用来计数的名词。可数名词有单数和复数形式。如：desk-desks,apple-apples等。不可数名词是不可以直接用来计数的名词。不可数名词没有复数形式，只有单数形式。如：some bread， alittle milk等。
2、单数可数名词表示泛指时，前面要用不定冠词a(an)，表示特指时，前面要用定冠词the;而不可数名词前不能用a(an)修饰，表示特指时，前面一定要用定冠词the。如：
Heis a factory worker. 他是一名工人。
Noone can see air. 没有人能看见空气。
3、可数名词和不可数名词前都可以用some,any, a lot of, lots of 等来修饰，表示"一些，许多"。如：
There are someoranges on the desk. 桌子上有一些桔子。
There is a lot ofwater in the bottle. 瓶里有许多水。
4、可数名词前可用具体的数词来表示具体的数量。如：twoapples, four books等。不可数名词前通常用"单位词+of"来表示数量。如： a piece of paper,three pieces of paper等。
5、可数名词作主语时，谓语动词的单复数与主语的单复数保持一致。如：
This picture isvery beautiful. 这幅画很美。
不可数名词作主语时，谓语动词要用单数形式，但是不可数名词前有复数"单位词"时，谓语动词要用复数形式。如：
There are twocups of tea on the table. 桌上有两杯茶。
6、对可数名词前的修饰语提问用howmany; 对不可数名词前的修饰语提问用how much。 如：
How many applesare there in the box?盒子里有多少个苹果？
How much tea isthere in the cup?杯里有多少茶水？
注意：对不可数名词前的"单位词"的修饰语提问时，疑问词用howmany。 如：
How many piecesof bread are there on the plate?盘子里有多少片面包？
单复数同形：
deer鹿 means 手段，方法
sheep 羊，绵羊 series 连续，系列
fish 鱼 species 种类
Chinese 汉语(单），中国人（复） works 工厂；作品
ethics 伦理学（单）；道德行为（复） statistics统计学（单）；数据（复）
名词可以分为可数名词与不可数名词，其中可数名词具有单复数的形式；而不可数名词没有可数名词复数变化规则如下：
1．一般情况下，直接加-s，如：book-books,bag-bags, cat-cats, bed-beds
2．以s. x. sh.ch结尾，加-es，如：bus-buses, box-boxes, watch-watches
3．以“辅音字母+y”结尾，变y为i,再加-es，如：family-families,strawberry-strawberries
4．以“f或fe”结尾，变f或fe为v,再加-es，如：knife-knives
5.以o结尾，有生命的加es, 无生命的加s. 如：potato-potatoes.zoo-zoos
6．不规则名词复数：
man-men,woman-women,
policeman-policemen,policewoman-policewomen,
mouse-micechild-children, foot-feet,.tooth-teeth,
fish-fish,sheep-sheep people-people, Chinese-Chinese,Japanese-Japanese,
当people后加上s时即peoples表示“民族”例如
There are 56peoples in China.
以下词为常为不可数名词，他们的复数形式就是他们本身。water(水) milk(牛奶) tea(茶) rice(米饭)orange（橙汁）juice（果汁）bread（面包）
不可数名词的数量关系可借助量词表示，如。acup of tea two cups of tea
