可数名词与不可数名词:从名词所表示的事物的性质来看,名词分为可数名词与不可数名词两类。可数名词有复数形式,不可数名词一般没有复数形式。
可数名词:可数名词是可以计数的,它们分为单数和复数两种形式。
指单个人或事物时,用单数形式,a pencil
指两个或多个人或事物时,用复数形式,two pencils
名词复数变化规则:
(1)一般在词尾加-s。
book→books bag→bags
(2)以s,x, ch, sh结尾的名词,一般在词尾加-es。class→classes
(3)以“元音字母+y”结尾的名词,在词尾加-s. boy→boys
(4)以“辅音字母+y”结尾的名词,先将y变为i,再加-es。family→families
(5)以f或fe结尾的名词,变f或fe为v,再加-es. knife →knives
(6)一些以字母o结尾的名词变复数时有生命加-es,没有生命加-s
hero→heroes (英雄) potato→potatoes(土豆)
tomato→tomatoes (西红柿) photo→photos (照片)
(7)一些名词变化不规则
man →men child→childrenes
不可数名词:不可数名词没有复数形式,不能直接用数词来表示数量,如果要表示数量,必须借助其他词来完成。用“计量单位词+of短语”表示,其数量也应该通过of前面的名词来体现出来。
a glass of water 一杯水 two glasses of water 两杯水
a cup of tea 一杯茶 two cups of tea 两杯茶
a piece of bread 一片面包 two pieces of bread两片面包
还有一类词既可作可数名词又可作不可数名词,

oranges(橘子,可数)
chicken(鸡肉,不可数)
chickens (小鸡,可数)
