名词的不规则变化
名词变复数分为规则变化和不规则变化
名词变复数分为规则变化和不规则变化：一. 规则变化1) 一般情况在词尾加-s清辅音后读/s/ map-maps book-books浊辅音和元音后读/z/ bag-bags car-cars2) 以s, sh, ch, x等结尾的，加-es ，bus-buses watch-watches3) 以辅音字母+y结尾的，变y 为i再加es ，family---families baby---babies注意：以y结尾的专有名词变复数时，直接加s two Marys the Henrys 4) 以元音字母+y结尾的，直接加–s , boy-boys toy-toys key-keysholiday-holidays5）以辅音字母加o 结尾的名词变复数有两种形式：1. 无生命的物体后加s如：photo---photos piano---pianos2. 有生命的物体后加es如：potato--potatoes tomato--tomatoes hero---herosNegro---Negros这五个词速记口诀：黑人英雄爱吃西红柿土豆6）以元音字母加o 结尾的名词变复数时直接加-s如：radio---radios zoo---zoos bamboo---bamboos7）以f或fe 结尾的名词变复数时：1. 改f, fe 为v 再加es，如：wife---wives knife---knives wolf---wolves thief---thieves shelf---shelves half---halves leaf---leaves self---selveslife---lives连成口诀就是：妻子持刀去宰狼，小偷吓得发了慌，躲在架后保己命，半片树叶遮目光。
2. 直接加s，如：gulf---gulfs roof---roofs chief---chiefs surf---surfsbelief---beliefs proof---proofshandkerchief—handkerchiefs；连成口诀就是：海湾边，屋顶上，首领奴仆两相望，谁说他们没信仰，证据就在手帕上。
初中知识点归纳名词的复数形式与不规则变化与句型转换
初中知识点归纳名词的复数形式与不规则变化与句型转换在初中英语学习中，名词的复数形式和不规则变化以及句型转换都是必须掌握的重要知识点。
正确理解和使用名词的复数形式以及掌握名词不规则变化的规则可以帮助我们准确地表达意思，并且在句型转换时也能够运用得当。
本文将对初中英语学习中的这些知识进行归纳总结，以帮助同学们更好地掌握。
一、名词的复数形式名词的复数形式主要有以下几种情况：1. 一般情况下，向名词后加-s即可形成复数形式。
例如：book-books，desk-desks。
2. 在以s, x, sh, ch等有音“/s/”音的字母结尾的名词后加-es。
例如：box-boxes，watch-watches。
3. 以辅音字母+y结尾的名词，去y加-ies。
例如：baby-babies，city-cities。
4. 以-o结尾的名词，大多数情况下加-es。
例如：tomato-tomatoes，hero-heroes。
但也有少数例外，例如：photo-photos，piano-pianos。
5. 特殊名词的复数形式需要进行记忆，例如：man-men，woman-women。
二、名词的不规则变化除了常见的复数形式变化外，还有一些名词是不规则变化的，我们需要熟记这些不规则的变化形式。
1. 以f或fe结尾的名词，变复数时通常去f或fe，加-ves。
例如：leaf-leaves，knife-knives。
2. 一些名词的复数形式与单数形式完全不同，需要进行牢记。
例如：child-children，foot-feet。
3. 一些名词的复数形式与单数形式相同，需要根据上下文进行判断。
例如：deer-deer，sheep-sheep。
三、句型转换在英语学习中，对于名词的复数形式和不规则变化的掌握不仅限于表达单个名词，还需要能够在句型转换中正确运用。
下面以一些常见的句型转换为例进行说明。
1. 肯定句与否定句的转换在转换肯定句和否定句时，除了动词的变化以外，名词的复数形式也需要进行相应的变化。
名词变复数规则、不规则变化
规则变化
1、一般在名词词尾加s，
map—maps地图，bird—birds鸟，
orange—oranges 桔子，
bike—bikes自行车；
2、以s, x, ch, sh结尾的名词加es，
box—boxes盒子，class—classes班级，watch—watches手表，dish-dishes盘，碟子，餐具；
3、以O结尾的名词后面加s或es
photo—photos相片radio—radios收音机zoo—zoos动物园
tomato—tomatoes西红柿potato—potatoes土豆
4、以辅音字母加y结尾的名词，变y为i+es
baby—babies婴儿family—families家庭；
以元音字母加y结尾的名词直接加s
boy—boys男孩toy—toys 玩具；
5、以fe或f结尾的名词，把fe或f变为ves
knife—knives小刀
wife—wives妻子
leaf—leaves树叶。
不规则变化
一、元音发生变化
二、词尾发生变化
三、单数、复数形式不变
四、只有复数的名词
五、第一个或最后一个词变成复数
六、构成合成名词的两个词都要变为复数。
名词变复数不规则变化(参考模板)
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；（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, socks6.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 bottle.food 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。

不规则名词变化规律汇总
不规则名词复数形式变化规律1.以－f或－fe结尾的名词变复数（1）加－s，如：belief-beliefs roof-roofs gulf-gulfs（2）去f，fe加－ves，如：half-halves knife-knives leaf-leaves life-lives wolf-wolvesthief-thieves self-selves wife-wives shelf-shelves歌诀记忆：树叶（leaf）半数（half）自己（self）黄；妻子（wife）拿刀（knife）去割粮；架（shelf）后窜出一匹狼（wolf）；就像小偷（thief）逃命（life）亡。
这9个名词变复数时，都要改－f（e）为v，再加－es，其他的以－f（e）结尾的名词则直接加－s变复数。
2.以－o结尾的名词，变复数（1）加s，如：photo-photos piano-pianos radio-radios zoo-zoos kilo-kilos（2）加es，如：potato-potatoes tomato-tomatoes Negro-Negroeshero-heroes歌诀记忆：黑人（Negro）和英雄（hero）爱吃西红柿（tomato）和马铃薯（potato）。

(word完整版)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；(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， Germans5.一般只有复数，没有单数的有：people， shoes, glasses, gloves， shorts, clothes， socks6.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。

food 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。
名词：可数名词、不可数名词变化
名词：可数名词、不可数名词变化* 可数名词是可以用简单的数词进行计数的名词,如：box, child, orange, desk等.*不可数名词是不可以用简单的数词进行计数的名词。

名词单复数不规则变化汇总
1. 复数不规则变化名词child---children；foot---feet；tooth---teeth；mouse---mice；man---men；woman---women；注意：与man 和woman构成的合成词，其复数形式也是-men 和-women。
如：an Englishman，two Englishmen. 但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans。
2.单复同形如：deer，sheep，fish，Chinese，Japaneseli，jin，yuan，two li，three mu，four jin但除人民币元、角、分外，美元、英镑、法郎等都有复数形式。
如:a dollar, two dollars; a meter, two meters3. 集体名词，以单数形式出现，但实为复数。

b. news 是不可数名词。

The United Nations was organized in 1945. 联合国是1945年组建起来的。
d. 以复数形式出现的书名，剧名，报纸，杂志名，也可视为单数。
名词的单复数形式及不规则变化
名词的单复数形式及不规则变化名词是我们日常书写和口语表达中最基本的语法成分之一，它们可以用来表示人、物、地点、抽象概念等等。
而名词的单复数形式以及不规则变化则是我们在使用名词时需要了解和熟练掌握的重要知识点。
本文将为您介绍名词的单复数形式及不规则变化，希望对您的学习有所帮助。
1. 名词的一般变化规则大部分名词在构成复数形式时，只需要在词尾加上-s即可。
例如：book（书）→books（书籍），cat（猫）→cats（猫咪），table（桌子）→tables（桌子们）。
此外，以辅音字母+y结尾的名词，将y变为i再加上-es构成复数形式。
例如：baby（宝宝）→babies（宝宝们），lady （女士）→ladies（女士们）。
2. 名词的不规则变化然而，并非所有名词都遵循上述的一般变化规则，一些名词存在不规则的变化方式。
下面列举几种常见的不规则名词变化形式：- 不变复数：一些名词在单数和复数形式上形态完全相同，即复数形式和单数形式相同。
例如：sheep（绵羊），fish（鱼），deer（鹿）。
- 变元复数：一些名词的复数形式与单数形式完全不同。
例如：man （男人）→men（男人们），woman（女人）→women（女人们），child（孩子）→children（孩子们）。
- 变化元音：一些名词在复数形式上变化其元音。
例如：foot（脚）→feet（脚），tooth（牙齿）→teeth（牙齿）。
- 不变单数：一些名词在单数和复数形式上形态完全相同，即复数形式和单数形式相同。
例如：series（系列），species（物种），sheep （羊）。
- 没有复数形式：一些名词没有复数形式，只存在单数形式。
例如：advice（建议），information（信息），furniture（家具）。
需要注意的是，虽然存在不规则变化形式，但英语中大部分名词的复数形式还是遵循一般变化规则的。
综上所述，名词的单复数形式以及不规则变化是英语学习中的基础内容之一。
英语语法：名词的不规则变化
名词的不规则变化 1) 元⾳字母发变化。
