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:

⑴绝大多数名词直接在词尾加s变成复数,如:cup—cups, bathroom-bathrooms

⑵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

⑶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。 ⑷以y结尾的名词变复数时视以下两种情况而变:

① 元音+y:直接+s ,如:boy—boys, toy—toys, day--days

②辅音+y:变y为i,再+es ,如:study(书房)—studies, city(城市)—cities, party(晚会)-parties ⑸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:zoo-zoos, radio-radios, photo-photos, piano-pianos, zero-zeros, bamboo(竹竿)--bamboos, tobacco(烟丝)--tobaccos

2)两人两菜一水果。(+es)

小学-中学课本中以o结尾的名词构成复数时,加es的只有Negro(黑人),hero(英雄),potato(土豆),tomato(西红杮),mango(芒果)这就是“两人两菜一水果”。

3)其余以o结尾的名词变复数时均加s。

图景:你在“zoo”里,看见一要“bamboo”,上面挂着一张“photo”,所照的是一架“piano”,上面放着一台“radio”。

zoo-zoos , bamboo-bamboos, photo-photos piano-pianos, radio-radios.
