名词变复数规则及练习（含五篇）第一篇：名词变复数规则及练习名词一．名词的数名词分可数名词和不可数名词两大类 1.不可数名词A.不可数名词没有单复数之分，包括专有名词抽象名词和物质名词例如：抽象名词health 健康advice 建议物质名词water 水air 空气wood 木头专有名词America 美国China 中国Mike 人名B.表示学科名称以ics 结尾的名词常做单数例如：physics 物理mathematics 数学2.可数名词可数名词有单数和复数之分A．一般情况下在词尾直接加 s例如： tables 桌子books 书friends 朋友 B.以 s，x，ch，sh结尾的名词后加 es 例如： bus-buses 公车box-boxes 盒子brush-brushes 刷子watch-watches 手表例外：stomach-stomachs 胃C.一些以辅音字母加o结尾的单词加es 例如： hero-heroes 英雄tomato-tomatoes 西红柿potato-potatoes 土豆口诀：黑人和英雄喜欢土豆和西红柿Negroes and heroes like potatoes and tomatoes.很多以o结尾的单词变复数时只加s，pianos 钢琴photos 照片zoos 动物园等 D.以辅音字母加y结尾的单词，把y变为i加es。

英语名词变复数的规则及练习题第一篇：英语名词变复数的规则及练习题英语名词变复数的规则及练习题1.名词名词可以分为专有名词和普通名词，专有名词是某个（些）人，地方，机构等专有的名称，如Beijing，China等。
普通名词是一类人或东西或是一个抽象概念的名词，如：book，sadness等。

2）集体名词：表示若干个个体组成的集合体，如：family。
3）物质名词：表示无法分为个体的实物，如：air。
4）抽象名词：表示动作、状态、品质、感情等抽象概念，如：work。
个体名词和集体名词可以用数目来计算，称为可数名词，物质名词和抽象名词一般无法用数目计算，称为不可数名词。

在英语中，大部分名词的复数形式是通过在词尾加上"s"或"es"来构成的。
然而，也存在一些特殊规则和例外情况。
本文将探讨名词复数形式的构成规则，并提供一些习题范例来帮助读者加深理解。
一、名词复数形式的构成规则：1. 在大部分情况下，只需在名词的词尾加上"s"来构成复数形式。
例如：- book → books (书→ 书籍)- dog → dogs (狗→ 狗们)- car → cars (汽车→ 汽车们)2. 若名词的词尾是"ch"、"sh"、"s"、"x"或"z"，则需要加上"es"。

例如：- city → cities (城市→ 城市们)- baby → babies (婴儿→ 婴儿们)- fly → flies (苍蝇→ 苍蝇们)4. 名词的词尾是元音字母+y时，只需加上"s"。
例如：- day → days (天→ 天数)- boy → boys (男孩→ 男孩们)- key → keys (钥匙→ 钥匙们)5. 若名词的词尾是"f"或"fe"，则通常将"f"或"fe"变为"ves"。
