名词变复数及三单变化规则总结

名词变复数及三单变化规则总结

第一篇:名词变复数及三单变化规则总结

名词变复数规则:

1.一般名词复数是在名词后面加上“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:photo→photos,piano→pianos,radio→radios,zoo→zoos b)加es的名词有: 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);

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;9.最特殊的一个:German-Germans.第三人称单数时动词变化规则:

1、一般现在时主语为第三人称单数时的动词变化

①在一般现在时中,当主语为第三人称单数时,动词要用“s”型(即第三人称单数形式)。

②所谓动词“s”型的构成,可按名词变复数的规则来记,即: i)在动词尾直接加 s。如:play—plays,want—wants,work—works,know—knows,help—helps,get—gets)ii)以字母s、x、ch、

sh或o结尾的动词加-es;如:guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch—watches,catch—catches)iii)以辅音字母+y结尾的动词,先变y为i,再加-es。如:study—studies,carry—carries,fly—flies,worry—worries

动词加ing变化规则:

1、一般情况下,在动词原形后面直接加ing,-going ,doing, walking, talking, speaking, sleeping,cooking.2、以不发音的e 结尾,去e加ing,(刮脸)-shaving,coming,

living, dancing, making.3、在少数几个以 –ie 结尾的动词后:须将–ie 变作y,再加-ing。(这些动词词典一般均注明) – dying;tie –

tying,lie – lying

4、在闭音节的单音节动词后、以重读闭音节结尾的多音节动词,而末尾只有一个辅音字母时,将这个辅音字母双写(x除外),然后再加 – – sitting;run – running;begin – beginning;forget –

forgetting 特别要注意:这和第三人称一般现在时的词尾变化不同,动词词尾如为“辅音字母 + y” 时不变,在其后直接加 –ing。 – studying;carry– carrying;fly – flying;worry – worrying

第二篇:名词单复数变化

名词的单复数形式变化

一、最常见的就是直接在名词后面+s Boy—boys(男孩)cat—cats(猫)room—rooms(房间)horse—horses(马)tree—trees(树)rose—roses(玫瑰)

二、如果名词是以x、s、sh、ch结尾的,在名词后面+es

Branch—branches(树枝)match—matches(火柴)fox—foxes(狐狸)class—classes(班级)bus—buses(公交车)Box—boxes(箱子)watch—watches(手表)dish—dishes(盘子)coach—coaches(车厢)couch—couches(沙发)

三、如果名词是以辅音加y结尾的,要变y为i加es;如果不是以辅音结尾的,就直接在y后面加上s Family—families(家庭)

study—studies(学习)party—parties(派对)baby—babies(宝贝)city—cities(城市)

Boy—boys(男孩)toy—toys(玩具)way—ways(方法、路)monkey—monkeys(猴子)key—keys(钥匙)

四、当名词是以fe或f结尾的,要变fe或f为v,再加es;有的直接加s Thief—thieves(小偷)shelf—shelves(书架)leaf—leaves(树叶)half—halves(一半)Wolf—wolves(狼)life—lives(生活、生命)wife—wives(妻子)knife—knives(刀)Roof—roofs(房顶)belief—beliefs(信念)proof—proofs(证据)

五、当名词是以o结尾有生命的加es,没有生命的加s Potato—potatoes(土豆)tomato—tomatoes(西红柿)

hero—heroes(英雄)Photo—photos(相片)zoo—zoos(动物园)radio—radios(广播)piano—pianos(钢琴)

六、名词复数不规则变化

Child—children(小孩)mouse—mice(老鼠)man—men(男人)woman—women(女人)German—Germans(德国人)

Englishman—Englishmen(英国人)Frenchman---frenchmen(法国人)foot—feet(足,脚)tooth—teeth(牙齿)1)单复数同形

Deer—deer(鹿)fish—fish(鱼)Chinese—Chinese(中国人)Japanese—Japanese(日本人)2)集体名词,名词以单数的形式出现,但是实际上是指的复数 People(人们)police(警察)public(公众)

第三篇:名词变复数不规则变化

名词变复数不规则变化:

1.单词内部发生变化:口诀“oo常常变ee,男人女人a变e”

eg:foot→feet脚;tooth→teeth牙齿;man→men男人;woman→women女人; 2.单复数相同:“羊鱼小鹿无变化,单数复数是一家”

eg:sheep→sheep绵羊;fish→fish鱼;deer→deer鹿;

3.不规则变化:child→children孩子;mouse→mice老鼠;

4“某国人”的复数有三种类型: 口诀“中日不变,英法变,其它S加后边”

(1)Chinese, Japanese单数复数同形,不需加s;

1(2)Englishman, Frenchman, Dutchman复数要把 man 变为men;

(3)其他各国人以–an,-ian收尾的均直接加s。如:Americans,

Australians, Germans 5.一般只有复数,没有单数的有:people,

shoes, glasses, gloves, shorts, clothes, socks 6.代词的复数: It, he,

she →they;I→we;you→you;this→these;that→those

二.不可数名词:

⒈不可数名词概念:不可以数出数目的名词叫做不可数名词。

⒉不可数名词特点:

⑴不可数名词没有复数形式,也不能与a, an及数词连用,常作单数看待。

例: water

There’s some water in the

My favourite food is noodles.⑵不可数名词如表数量,常和a

bottle of, a glass of a pieces of 等名词词组连用。如表示复数,只把量词改为复数。

例:a bottle of pop一瓶汽水 , two glasses of orange juice 两杯桔子汁,three cups of tea 三杯茶,a piece of paper一张纸

⑶有些物质名词有时可数,有时不可数,要根据上下文决定,其意义也有所不同。

Glass(玻璃)glasses(眼镜)

⑷集体名词看作整体时,谓语用单数;指成员时,谓语用复数。

His family is a large family like animals.指整体

指成员

⑸有的名词单复数意思不同:

例:hair 和fruit 通常作单数,表示总体。My hair is black.我的

头发是黑色的。I like ’s good for you.我喜欢水果,水果对你的身体有好处。

但如果表示若干根头发或各种水果,则需用复数形式.Danny has

three hairs.丹尼有三根头发。She likes pears, peaches and other

fruits.他喜欢梨,桃和其它水果。
