一、变内部元音

foot-feet

man-men

mouse-mice

tooth-teeth

woman-women

二、词尾加-en

child-children

ox-oxen

三、形式不变,即单复数同型(通形名词)

deer-deer

fish-fish

means-means

series-series

sheep-sheep

四、加-es(是加-s的'特殊情况)

match-matches

tomato-tomatoes

五、去y改i加-es或去f改v加-es(亦为加-s的特殊情况)

leaf-leaves

六、外来词的不规则变形

ovum-ova

locus-loci

basis-bases

(不少外来词有两种复数形式)

focus-foci/focuses

cactus-cacti/cactuses

fungus-fungi/funguses

规则 变形 :

1)一般情况下(大多数)词尾加s:

book→ books

pen → pens

bag → bags

teacher→ teachers

parent→ parents

tree→ trees

2)名词以s, x, sh, ch结尾时,(为了发音清晰)加es:

kiss→kisses

tax→ taxes(税)

brush→ brushes

lass→lasses(小姑娘)

box→ boxes

wish→ wishes

peach→ peaches

match→ matches

3)以o结尾的名词有些加es,有些加s:

tomato→ tomatoes

potato→ potatoes

echo→ echoes(回音)

hero→ heroes(英雄)

Negro→ Negroes(黑人)

veto→ vetoes(否决)

但以两个o或者两个元音字母结尾时只加s(如果再加es,则有ooe三个元音连在一起,不太好念。英语中很少允许三个元音字母在一起):

bamboos(竹)

radios

zoos

cuckoos(布谷鸟)

kangaroos(袋鼠)

studios(画室)

embryos(胚胎)

有些以o结尾的外来词只加s:

photos(照片)

solos(独唱 )

pianos(钢琴 )

kilos(千克 )

memos(备忘录)

Filipions(菲律宾人)

Eskimos(爱斯基摩人)

有些加s或者es都可以:

motto(e)s(座佑铭)

cargo(e)s(货物)

volcano(e)s(火山)

buffalo(e)s(水牛)

banjo(e)s(班卓琴)

tornado(e)s(龙卷风)

4)以“辅音字母+y”结尾时,改y为i,再加es(便于发音清晰):

city→ cities

country→ countries

county→ counties(县)

注意:“元音+y”结尾时不能改y,直接加s,因为如果改y为i, 整个词形和发音会产生很大影响:

√boy → boys

√toy → toys

√guy → guys

×box → bois

5)以f或者fe结尾的名词,多数变f为v再加es(为了发音清晰):

wife→ wives

self→ selves

loaf→ loaves (面包片)

wolf→ wolves (狼)

thief→ thieves

knife→ knives

shelf→ shelves (书架)

half→ halves

leaf→ leaves

但是,“两个元音字母+f”结尾时只加s(不能再变f为浊音v再加es,那样听起来会太硬):

roof → roofs(屋顶)

proof → proofs(证据)

chief → chiefs(首领)

hoof → hoofs(马蹄)

个别词两种形式都可以:

scarf→ scarfs, scarves(围巾)

dwarf→ dwarfs, dwarves(矮人)

handkerchief→ handkerchiefs, handkerchieves(手巾)
