范文一:单数变复数变化规则
可数名词单数变复数规律:
1、词尾直接加s 型:students, apples, bags, trees, books, brothers
2、以s 、x 、sh 、ch 结尾的名词加es 型:glasses, boxes, brushes, matches
3、以辅音字母加y 结尾的名词,变y 为i 加es 型:city-cities, baby-babies
4、以元音字母加y 结尾的名词,直接加s: boys, toys
5、以f 或fe 结尾的名词,多数变f 为v 加es: wives, knives, thief, life, half, leaf,
shelf, wolf, 除了roof
6、以o 结尾的名词,一般直接加s: radios, zoos, pianos, photos;除了5个特殊的词需要加 es: Negroes, heroes, potatoes, tomatoes,mangoes.(黑人英雄爱吃土豆和西红柿:薯条蘸番茄酱; 最后再吃点芒果)
7、不规则变化的词:foot → feet, goose→ geese, tooth→ teeth, man → men, woman→ women, sheep → sheep, deer→deer Chinese →Chinese, Japanese→Japanese ,child
→ children,mouse → mice.
不规则变化要特别记,oo 常常变ee, foot →feet 是一例; 男人、女人a 改e, woman →women 是一例;child 复数children 要记准,中、日、鹿、绵羊无变化,单数、复数是一家。

名词复数:bed(beds), tree(trees),
动词第三称单数:help(helps), play(plays)
2. 两者以s ,x ,ch ,sh结尾的词,在词尾加-es,原词尾已有e,一般只加-s都读作[iz]。如: 名词复数:box(boxes), orange(oranges)
动词第三人称单数:wash(washes), close(closes) 3. 以辅音字母加-y结尾的词,先变y为i,再加-es,读作[iz]。如:
名词复数:factory(factories), baby(babies) 动词第三人称单数:fly(flies), study(studies) 二、构成方式的不同点
1. 名词复数方面
1)有些名词的单、复数形式相同。如:sheep(sheep), Chinese(Chinese) 2)有些名词的复数形式是特殊的,不规则的。如:man(men), child(children) 3)以o结尾的名词,有的加s,也有的加es。如:radio(radios), phono(phonos),

(1)以o结尾的动词加es。如:go(goes), do(does)
(2)不规则的。如:have(has)
