Language points
可数名词与不可数名词
1.分辨可数名词和不可数名词
（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、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“不定冠词/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
等修饰；不可数名词前可用much, some, any,
little, a little等修饰。
many teachers 许多教师
much money 许多钱
（4）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。
How many books do you have
你有多少本书？
How much salt do we need
我们需要多少盐？
2.可数名词的复数
名词复数的变化分规则变化和不规则变化两种。
（1）规则变化
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：
情况 构成方法 读音
一般情况
加-s
在清辅音后读/s/
在浊辅音和元音后读/z/
在/t/后读/ts/
在/d/后读/dz/
情况 构成方法 读音
以s, x, ch, sh等结尾的大多数词
加-es
读/Iz/
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
（2）不规则变化
①改变单数名词中的元音字母。
如：man → men男人 tooth → teeth牙齿
②词尾有变化。
如：child → children孩子 mouse → mice老鼠
③单、复数形式相同。
如：sheep → sheep绵羊 deer → deer鹿
（3）通常情况下，当一个名词作定语修饰另一个名词
时，其复数形式只须将其主体词变为复数形式。
但man或woman修饰另一个名词，变复数时要将
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
