可数名词有单数和复数两种形式。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复数形式。名词由单数形式变成复数形式的规则如下： 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 (规律：man → men) ③ tomato → tomatoes potato → potatoes
[悄悄话： 初中英语以o 结尾的名词变复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 sheep, Chinese, Japanese单、复数同形 [悄悄话：变复数时词形不变。] ⑥ people单数形式表示复数意义，要求谓语动词用复数； people的复数形式peoples通常指"多个民族"。 三、 不可数名词的家务事
1. 不可数名词没有复数，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，有复数形式，但他们的意义往往发生变化。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
