1、名词由单数变复数的基本方法如下:
①在单数名词词尾加s。如:map
→
maps,boy→
boys,horse→
horses,
table→
tables.
②s,o,x
,sh,ch结尾的词加es.如:class→classes,
box→boxes,
hero→heroes,
dish→dishes,
bench→benches.
[注]:少数以o结尾的词,变复数时只加s。如:photo→photos,
piano→pianos.
③以辅音字母加y结尾的名词,变y为i,再加es。如:family→families,
city→cities,
party→parties.
④以f或fe结尾的名词,变f或fe为v,再加es。如:shelf→shelves,
wolf→wolves,
life→lives,
knife→knives.
2、不规则变化:man→men,
woman→women,
sheep→sheep,tooth→teeth,
fish→fish,
child→children,
ox→oxen,
goose→geese
不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。如:a

of

bags
of
rice,
a
piece
of
paper→three
pieces
of
paper,
a
bottle
of
milk→five
bottles
