bus可数名词的复数形式篇一
不可数名词都默认为单数,所以总是用is或者was;最好不要根据some、any、a lot of等词去作判断,以免受误导。
可数名词如何变“复数形式”:
a.一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds ;读音:清辅音后读[s],浊辅音和 元音后读[z]。b.结尾,加-es,如:bus-buses, box-boxes, brush-brushes, watch-watches ;读音:[iz]。
c.以“辅音字母+y”结尾,变y为i, 再加-es,如:family-families, strawberry-strawberries ;读音:[z]。
d.以“f或fe”结尾,变f或fe为v, 再加-es,如:knife-knives,thief-thieves;读音:[z]。e.以“o”结尾的词,分两种情况
1)有生命的+es 读音:[z] 如:mango-mangoes(芒果)
两人两菜一火山:hero(英雄)negro(黑人)tomtato(西红柿)potato(土豆)volcano(火山)2)无生命的+s
读音:[z] 如:photo-photos
radio-radios f.不规则名词复数: man-men, woman-women, policeman-policemen, policewoman-policewomen,snowman-snowmen, mouse-mice, child-children, foot-feet, tooth-teeth, 单复数形式相同:fish, deer,sheep-,people, chinese, japanese。
2、不可数名词没有复数。如果要计算不可数名词所表达的数量,就得在数词和不可数名词之间加上“量词+of”。例如:a glass of water, a piece of paper, a bottle of juice 判断步骤:
↗如是am、is或was→原形 读句子→读该单词→认识该单词→理解意思→看be动词
↘如是are或were→加s或es 练习题

可数名词及其单复数
更多知识点关注微信公众平台:菁优英语 1一般现在时的构成
一、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,a little milk等.二、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:
he is a factory one can see air.没有人能看见空气.三、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 some oranges on the is a lot of water in the bottle.瓶里有许多水.四、可数名词前可用具体的数词来表示具体的数量.如:two apples,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.五、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 is very 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:

bus可数名词的复数形式篇五
名词的数
(一)规则变化:
1.一般名词的复数形式是在词尾直接加-s构成。如: page→pages pen→pens student→students 2.以-s,-x,-ch,-sh结尾的名词,变成复数时在词尾加-es。如: class→classes box→ boxes brush→ brushes watch→watches 3.以-f和-fe结尾的词变f或fe为v,再加-es。如: leaf→ leaves knife→knives wife→wives 注意:roof,gulf,belief,chief,safe,proof,staff等其复数直接在词尾加-s。handkerchief的复数为handkerchiefs或handkerchieves.
4.以辅音字母加一y结尾之名词,先将y变成i,再加-es。如: party-→parties story→stories university→universities 5.以字母o结尾的词,一般来说,生物名词,包括动、植物名词加-es构成复数。例如: negro→ negroes黑人 hero→ heroes英雄 potato→potatoes土豆tomato→ tomatoes西红柿 以-o结尾的无生物名词一般直接加-s构成复数。例如:
photon→ photos照片piano→pianos钢琴 kilo→kilos公斤tobacco→tobaccos烟草 外来的有生物以-o结尾的名词也只加—s构成复数。例如: eskimo→ eskimos爱斯基摩人 filipino-→filipinos菲律宾人(二)不规则变化:
1.变化名词中所含的元音字母。如:
foot-→feet tooth→ teeth goose→geese man→men 2.词尾加-en或-ren。如: child→ childlien ox→oxen 3.单复数同形。如:
sheep,deer,fsh,means(方法),aircraft(飞机)4.表“某国人”的名词,其复数变化有3种情况。(1)单复数形式相同。如:
a chinese→ ten chinese;a japanese→ five japanese(2)变词尾的.man/woman。如:
frenchman→ frenchmen;englishman→englishmen dutchman→dutehmen;englishwoman→englishwomen(3)词尾加-s。如:
german→ germans;russian→ russians;american→ americans 口诀记忆法:中日同形用不变,英法同盟变a为e,其他一律加s。
5.有一些词如hair(头发),fruit(水果),通常是用它们的单数形式来表示总称。但在表示“几根头发”,“若干种水果”时,则要用复数形式。如:
a few white hairs几根白发several foreign fruits几种外国水果 常用复数的可数名词
有些衣物和工具,如“裤子”“剪刀”等是由相似的两部分组成的,通常用复数。
briefs 贴身短内裤;compasses 圆规;glasses 眼镜;jeans 牛仔裤;leggings 绑腿;pants 短裤pajamas 睡衣scales 天平;scissors 剪刀;shorts 短裤;spectacles 眼镜;sunglasses 太阳镜;tights 紧身衣;tongs 钳子trousers 裤子
如:where are my pajamas? 我的睡衣在哪里?my trousers are too long.我的裤子太长了。如果要表示一件衣服或一件工具要用a pair of: he was wearing a pair of gray trousers.他穿一条灰色长裤。lisa has three pairs of jeans.莉萨有三条牛仔裤。
一副手套,一双鞋,一双袜子也是用“a pair of”表示a pair of new gloves 一副新手套 a pair of shoes 一双鞋a pair of old socks 一双旧袜子。
因为手套,鞋子,袜子是可以拆开而独立存在的,所以它们不属于常用复数的名词。复数形式与原义不同一些名词的复数形式具有与原来不同的含义,常用复数。
damage 伤害damages 赔偿金good 好goods 货物green 绿色greens 青菜ground 地面grounds 围院
import 进口imports 进口货look 看looks 外貌manner 方式manners 礼貌 minute 分钟minutes 记录paper 纸papers 文件ruin 毁灭ruins 废墟time 时间times 记录troop 群troops部队
如:your manners are improving.你的礼貌有长进。
imports from africa included coffee, cocoa and olive oil.来自非洲的进口物品包括咖啡、可可和橄榄油。
(三)复合名词的复数
1.一般将主体名词变为复数。mother-in-law→ mothers-in-law岳母 passer-by→passers-by过路人
looker-on→lookers-on旁观者 editor-in-chief→editors-in-chief主编 2.无主体名词构成的复合词,在词尾加一s。如:
go-between→ go-betweens中间人,媒人 grown-up→grown-ups成年人 3.由man或woman构成的复合名词,两者都要变成复数。如:
a man teacher→ two men teachers; a woman doctor→ ten women doctors 注意:有一些名词,包括一些学科名词,形式上为复数,但意义上却是单数。如: news(消息); mathematics(数学); physics(物理); politics(政治)(四)不可数名词的数
1.不可数名词就是表示无法分清个体的名词。这类词主要为抽象名词和物质名词。计算不可数名词时,用“数词或冠词+量词+0f+不可数名词”这样的结构来表示,量词可以是单数也可以是复数.但of后的名词只用单数。如:
a piece of apple pie一块苹果派 two cups of tea两杯茶 three items of news三条消息 four buckets of water四桶水 a drop of water一滴水 a ray of hope一线希望 2.有些物质名词可用复数形式表示数量或不同的类别。如: two coffees,please.请来两杯咖啡。
the old should take some heath foods.老年人应食用些保健品。3.有些抽象名词可以用单数或复数形式表示具体的事物。如:
difficulty困难→difficulties难事 success成功→ a success一个成功的人或一件成功的事
