可数名词及其单复数的定义

可数名词：

是指能以数目来计算，可以分成个体的人或东西；因此它有复数形式，当它的复数形式在句子中作主语时，句子的谓语也应用复数形式。

1）以y 结尾的专有名词，或元音字母+y结尾的名词变复数时，直接加s变复数：

如：　two Marys　　　　 the Henrys

monkey---monkeys　holiday---holidays

比较：层楼：storey---storeys　 story---stories

2）以o 结尾的名词，变复数时：

a. 加s，如： photo---photos　　piano---pianos

b. 加es，如：potato--potatoes　tomato--tomatoes

c. 均可，如：zero---zeros / zeroes

3）以f或fe 结尾的名词变复数时：

a. 加s，如： belief---beliefs　roof---roofs

safe---safes　 gulf---gulfs；

b. 去f,fe 加ves，如：half---halves

knife---knives　leaf---leaves　wolf---wolves

wife---wives　life---lives　thief---thieves；

c. 均可，如：handkerchief:

handkerchiefs / handkerchieves

2、可数名词复数的不规则变化

1）child---children　foot---feet　tooth---teeth

mouse---mice　　　man---men　 woman---women

注意：与 man 和 woman构成的合成词，其复数形式也是 -men 和-women。

如：an Englishman，two Englishmen. 但German不是合成词，故复数形式为Germans；Bowman是姓，

其复数是the Bowmans。
