可数名词和不可数名词一、名词：名词是所有事物的名称，包括人、物及抽象概念。
名词分为普通名词和专有名词两大类。
名词在句子中作主语，宾语或表语等。
1) 可数名词（Countable Nouns）: 一般来说个体名词和集体名词可以用数目来计算，称为可数名词。
可数名词有单数和复数两种形式。
例如: a book, two books, a student, three students, a family, many families。
名词单数变复数变化如下：◆词尾直接加s如：cat——cats bag——bags day——days◆以s, sh, ch, x 结尾的词加es如：class——classes, match——matches ,box----- boxes, dish ---- dishes, bus --- buses, peach --- peaches .◆以辅音加y结尾的词变y为i加es. 元音加y 结尾的词直接加s,如: party----parties city----cities story----stories family---families baby --- babies boy---- toys monkey----- monkeys key---- keys等.◆以f或fe结尾的词, 变f或fe 为v, 加es,如: wife ---- wives, half---- halves, shelf—shelves, knife --- knives, life---lives, leaf---leaves. 注意特殊情况直接加“s”，要逐个记chiefs, handkerchiefs , roofs.◆以辅音加o 结尾的词常加es, 如: tomatoes, potatoes, heroes. 元音加o结尾直接加s. 如:radios, zoos, pianos, 特殊情况: photos◆名词单数变复数特殊变化也要逐个记得如: man-men, woman-women, tooth---teeth, goose---geese, foot---feet, child--children, mouse-mice, ox—oxen.（注意：以下单复同形：deer, sheep, species, means, Chinese, Japanese）2) 不可数名词（Uncountable Nouns）不可数名词不能用数字计算包括物质名词( air, water等)及抽象名词(advice, hate)等。
所以它通常只有单数形式。
如：English, air, water, cotton, work…不可数名词表示数量时，可以用量词来表达(量词有复数形式)其结构是数词+量词+OF+名词。
如：a bottle of water, two cups of tea, three pieces of paper不可数名词的类别：●食物：food ,salt, bread, rice, beef, meat, pork, butter（黄油）,cream.●液体：water, juice, milk, coffee, tea, coke, oil, wine.●表示自然现象：snow, ice ,rain, air.●其他类：money, news ,homework, housework, advice（意见）,information（信息，资料）time, work , room(空间), music, weather ,space, sand, furniture（家具）,注意：下列词语在不同含义下词性的不同。
