名词

一、可数名词与不可数名词的区别

普通名词所表示的人或事物是可以按个数计算的，这类名词叫可数名词。可数名词分为个体名词(表示某类人或事物中的个体，如worker, farmer, desk, factory等)和集体名词(表示作为一个整体来看的一群人或一些事物，如people,family 等)。

如果普通名词所表示的事物是不能按个数来计算的，这类名词就叫不可数名词。不可数名词分为物质名词(表示无法分为个体的物质，如meat, rice, water, milk, orange 等)和抽象名词(表示动作、状态、情况、品质等抽象概念，如work, homework, time, health, friendship等)。

二、可数名词

可数名词有单数和单数两种形式。指一个人或一件事物时，用单数形式；指两个或多个人或事物时用单数形式。名词由单数形式变成单数形式的规则如下：

1. 一般的名词词尾直接加-s 。

如：book → books room → rooms house → houses day → days

2. 以s,ss, ch,sh, x 结尾的名词，在词尾加-es 。

如：bus → buses glass → glasses watch → watches dish → dishes box → boxes

3. 以"辅音字母+y"结尾的名词，要先将y改为i再加-es。

如：city → cities body → bodies factory → factories等等。

4. 以f 或fe 结尾的名词，要将f或fe改为v再加-es。

如：half → halves leaf → leaves knife → knives wife → wives

5. 特例[悄悄话：特例常常考，要记住。]

① child → children

② man → men woman → women policeman → policemen police woman-policewomen

③ tomato → tomatoes potato → potatoes [悄悄话：初中英语以o 结尾的名词变单数时只有这两个词加-es，其余的当然加-s喽！如：photo → photos ]

④ foot → feet tooth → teeth [悄悄话：oo变成ee。]

⑤ mouse-mice

⑥ fish, sheep, Chinese, Japanese单、单数同形[悄悄话：变单数时词形不变。]

⑦ people单数形式表示单数意义，要求谓语动词用单数；people的单数形式peoples通常指"多个民族"。

三、不可数名词

1. 不可数名词没有单数，当它作句子的主语时，谓语动词要用单数形式。

如：The food is very fresh.食品很新鲜。

2. 有的不可数名词也可以作可数名词，有单数形式，但他们的意义发生变化。

如：water (水) → waters (水域) orange (橘汁) → oranges (橘子)

3. 很多的不可数名词表示泛指时为不可数，表示种类时就可数，但意义大多不发生变化。

如：fruit → fruits food → foods fish → fishes hair → hairs
