Grammar
可数名词复数的变化规则
通常情况下，当一个名词作定语修饰另一个名词时，变复数时只把后一个名词变为复数。 但当man 或woman修饰另一个名词时， 变复数时要把man或woman和另一个名词一起变为复数。
an apple tree apple trees 苹果树
a woman leader women leaders 女领导
a man doctor men doctors 男医生
不可数名词
物质名词一般是不可数名词，它们所表示的事物不能用数来计数。如：rice, milk, yogurt, beef, …不可数名词的具体数量可以用适当的量词（由普通名词充当）作单位来表示，结构为“数词 + 量词（普通名词）+ of + 不可数名词”。其单复数变化就体现在量词上。如：a piece of paper 一张纸 three pieces of paper 三张纸。
不规则变化 例子 改变单词中间的元音字母 man-men woman-women
foot-feet tooth-teeth（牙齿）
mouse-mice goose-geese（鹅）
在词尾加-en/ren child-children ox-oxen（公牛）
单复数同形 sheep-sheep fish-fish
deer-deer（鹿） people-people
“某国人”变复数规则 中国、日本不变 Chinese-Chinese Japanese-Japanese
英国、法国a变e Englishman-Englishmen Frenchman-Frenchmen（法国人）
其余的国家加-s American-Americans German-Germans
（德国人）
可数名词复数的变化规则不规则变化：
二、不可数名词
1．物质名词：milk, water, rice
2．抽象名词：work, time, health
3．不可数名词的量的表达：数词＋量词＋of＋不可数名词。如：a piece of paper, two glasses of water/milk等。
三、既可数又不可数的名词
有些名词既能用作可数名词，又能用作不可数名词，但意义不同。
chicken—鸡(可数)；鸡肉(不可数)
room—房间(可数)；空间(不可数)
fish—鱼(可数)；鱼肉(不可数)
glass—玻璃杯(可数)；玻璃(不可数)
paper—试卷，报纸(可数)；纸张(不可数)
