可数名词有单数和复数两种形式。复数形式通常是在单数形式后加词尾“-s”构成，其主要变法如下：

（1）一般情况在词尾加-s，例如：book→books，girl→girls，boy→boys，pen→pens,doctor→doctors, boy→boys。

（2）以s，x，ch，sh，结尾的词加-es，例如：bus→buses，class→classe...

可数名词有单数和复数两种形式。复数形式通常是在单数形式后加词尾“-s”构成，其主要变法如下：

（1）一般情况在词尾加-s，例如：book→books，girl→girls，boy→boys，pen→pens,doctor→doctors, boy→boys。

（2）以s，x，ch，sh，结尾的词加-es，例如：bus→buses，class→classes，box→boxes，watch→watches，brush→brushes。

（3）以ce, se, ze,（d）ge结尾的名词加s，例如：orange—oranges。

（4）以辅音母加y结尾的词变“y”为“i”再加-es,例如：city→cities, factory→factories, country→countries, family→families。但要注意的是以元音字母加y结尾的名词的复数形式只加s，如：boy→boys, day→days。

（5）以o结尾的词多数都加-es。例如:hero→heroes，potato→potatoes，tomato→tomatoes,但词末为两个元音字母的词只加-s。例如：zoo→zoos，radio→radios，还有某些外来词也只加-s，例如：photo→photos，piano→pianos。

（6）以f或fe结尾的词，多数变f为v再加-es，例如：knife→knives，leaf→leaves, half→halves。

复数词尾s（或es）的读音方法如下表所示。

复数词尾s（或es）的读音方法


情 况
读法
例 词

在[p][t][k][f]等清辅音后
.[s]
cups, hats, cakes

在[s][z][t][ ][f]等音后


.[iz]
glasses, pages, oranges, buses, watches,faces

在[b][d][ g][v]等浊辅音后
.[z]
beds, dogs, cities, knives




（7）少数名词有不规则的复数形式，例如：man→men，woman→women，tooth→teeth，foot→feet，child→children，mouse→mice。

【注意】与man和woman构成的合成词，其复数形式也是-men和-women。例如：an Englishman，two Englishmen。但German不是合成词，故复数形式为 Germans；man, woman等作定语时，它的单复数以其所修饰的名词的单复数而定，如：men workers， women teachers。

有个别名词单复数一样，例如：Chinese，Japanese，sheep，deer，fish等。但当fish表示不同种类的鱼时，可以加复数词尾。
