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。

（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。

芦笋炒蘑菇fish 鱼肉（不可数名词）鱼的种类（可数名词）
room 空间（不可数名词）房间（可数名词）
glass 玻璃（不可数名词）杯子（可数名词）
