1、1可 数 名 词 的 复 数 变 化可数名词一般有单数和复数两种形式,名词由单数变成复数的变化分为规则变化和不规则变化两个大类。1.名词复数的规则变化:绝大多数名词直接在词尾加 s变成复数,如:cupcups, bathroom-bathrooms以 s, x, ch, sh结尾的名词变复数要加 es,如:class(班级)classes, box(盒子)boxes, match(火柴)matches, brush(刷子)brushes以 f或 fe结尾的名词变复数时,去 f或 fe再加 ves。f、fe 结尾的顺口溜:妻子持刀去宰狼,小偷吓得发了慌;躲在架后保己命,半片树叶遮月光。按:顺口溜

2、中的黑体字是中学阶段学过的九个以f(e)结尾的名词:wife(妻子),knife(小刀),wolf(狼),thief(小偷),shelf(架子),self(自己),life(生命),half(一半),leaf(树叶)。这九个词变复数时,都是改-f(e)为 ve再加-s。注意:以 f结尾的名词,一般把把 f改为 ves,但也有特殊情况是直接加-s 的,如 gulf(海湾), roof(屋顶), chief(首领), serf(农仆), belief(信仰), proof(证据), handkerchief(手帕) 。编成口诀联想:海湾边、屋顶上,首领农仆相望;谁说他们无信仰,证据定在手帕上。 以

3、 y结尾的名词变复数时视以下两种情况而变: 元音+y:直接+s ,如:boyboys, toytoys, day-days辅音+y:变 y为 i,再+es ,如:study(书房)studies, city(城市)cities, party(晚会)-parties以 o结尾的名词变复数时视以下三种情况而变:O结尾的名词顺口溜1)有生命的以 o结尾的名词变复数时,词尾加 es,凡无生命的以 o结尾的名词变复数时,词尾加 s。有生命:potato(土豆)-potatoes, tomato(西红杮)-tomatoes, hero(英雄)-heroes, Negro(黑人)-Negroes如无生命:z

6、mans, humanhumans, walkmanwalkmans表示民族的名词顺口溜(1) “中、日、瑞”友好是一致。(2) “英、法”联盟 a变 e。(3)其他一律加 s 即 Chinese,Japanese 单复数同形;Englishman,Frenchman 的复数为Englishmen,Frenchmen;其他像 German,American,Australian 等的复数形式是在后面加“s” 。在词尾加 en或 ren变成复数,如:oxoxen, childchildren,单复数同形,如:sheepsheep, deerdeer, ChineseChinese, Japane
