二、可数名词与不可数名词
名词按其所表示的事物的性质可分为可数名词和不可数名词。可数名词表示可以用数目计数的单词;不可数名词表示不能直接用数目计数的单词。
1. 可数名词和不可数名词的用法区别
(1) 可数名词有单数和复数两种形式，而不可数
名词只有单数形式。
pen →pens 钢笔（可数）
bread 面包（不可数）
(2) 不定冠词a/an、基数词可直接修饰可数名词，
表示数量；而不可数名词在表示数量时，
则用“冠词/基数词+表示计量单位的
名词+of+不可数名词”。
an apple 一个苹果
a piece of bread 一片面包
four cups of water 四杯水
(3) 可数名词复数前可用many, some, any, few, a few, a lot of, lots of等修饰；不可数名词 前可用much, some, any, little, a little, a lot of, lots of等修饰。
many teachers 许多教师
much money 许多钱
(4)可数名词作主语时，谓语动词与主语的单 复数保持一致。不可数名词作主语时，谓 语动词用第三人称单数形式。
注意：当不可数名词前表示计量的名词是 复数时，谓语动词用复数形式。
(5) 提问可数名词的数量用how many，提问
不可数名词的数量用how much。
例句：你有多少本书？
How many books do you have
我们需要多少盐？
How much salt do we need
情况 构成方法 读音
一般情况
2. 可数名词单数变复数的规则
(1) 规则变化
可数名词复数的构成，通常是在单数形式后面加s或es，其方法如下：
加-s
在清辅音后读/s/
在浊辅音和元音后读/z/
情况 构成方法 读音
以s, x, ch, sh等
结尾的大多数词
加-es
读/ z/
以辅音字母加y结尾的词
变y为i，再加-es
读/ z/
以f (e) 结尾的词
变f (e) 为v，
再加-es
读/vz/
以字母o结尾的名词有的加-es，有的加-s。
potato → potatoes 土豆
tomato → tomatoes 西红杮
radio → radios 收音机
photo → photos 照片
es和s都读/z/
(2)不规则变化
改变单数名词中的元音字母。
如：man → men 男人 tooth → teeth 牙齿
词尾有变化。
如：child → children 孩子
单、复数形式相同。
如：sheep → sheep 绵羊 deer → deer 鹿
(3) 当一个名词作定语修饰另一个名词时，一 般将 中心名词变为复数形式。但man或 woman修饰另一个名词，变复数时要将中 心名词及man或woman都变成复数。
a girl student → girl students 女学生
a woman teacher → women teachers 女教师
a man driver → men drivers 男司机
