语法讲解
1. 可数名词与不可数名词的区别
(1) 定义:
可数名词是能直接用数目进行计数的名词，如apple，cup；
不可数名词是不能直接用数目进行计数的名词，如water, milk。
(2) 特点：
可数名词有单、复数形式，如a bag→two bags ；
不可数名词没有复数形式，如rice。

语法讲解
可数名词与不可数名词
(3)表达：
可数名词可以直接用不定冠词a/an或具体的数词来修饰，如an egg, two pears；不可数名词不能直接用a/an或数词修饰；如果表示确切数量时，用“数量词+of+不可数名词”结构，如a glass of water。
可数名词也可以用“数量词+of+可数名词复数”结构，如a pair of shoes（一双鞋）
(4)谓语选择：
可数名词单数作主语时，谓语动词用单数形式；多个可数名词单数或可数名词复数作主语时，谓语动词用原形；不可数名词作主语时，谓语动词常用单数形式；当不可数名词前的数量词是复数时，谓语动词要用原形。

2. 可数名词复数形式的规则变化
(1) 一般情况加-s：bed-beds
(2)以s,x,ch,sh等结尾的词加-es：
glass-glasses；box-boxes；watch-watches；brush-brushes
(3)以辅音字母加y结尾的词变y为i再加-es：baby-babies
(4)以f，fe结尾的词
①把f，fe变为v再加-es：leaf-leaves；knife-knives
②直接加-s：roof-roofs
(5)以-o结尾的名词变复数加-es的有：
英雄（heroes）爱吃西红柿（tomatoes）和土豆（potatoes）
可数名词与不可数名词

单复数不同形：
man-men；woman-women；child-children；tooth-teeth；foot-feet

就转换为不可数名词。
