愛華網(wǎng)一、可數(shù)名詞指可以數(shù)清數(shù)量，可以分割成獨立個體的名詞（countable nouns can either be countedor are separable objects）。
二、不可數(shù)名詞：
1. 無法分割的名詞，只能看做一個整體(Nouns that have no distinct, separate parts,we look as a whole)。
air, fog, smoke, fog, oxygen
water, rain, oil, wine, glue, tea, coffee, yogurt, blood, honey,juice, milk, cream, gasoline, soup
sugar, salt, bread, meat, paper, butter, ice cream, cheese, ice,beef, pork, chicken, fish, copper, iron, gold, glass, chalk
2. 組成成分太小而不宜數(shù)的名詞(Nouns that have parts that are too small orinsignificant to count)。
rice, hair, sand, popcorn, salt, sugar, grass, corn, snow
3. 總稱名詞，側(cè)重于表示某類事物的總的概念，而不是具體的事物(Nouns that are classes orcategories of things)。
clothing, food, furniture, fruit, luggage, makeup, homework,housework, jewelry, money/cash, equipment, machinery, poetry,scenery, character
4. 抽象名詞（Abstraction）。
art, fun, life, patience, time, pollution, love, happiness,beauty, health, luck, truth, music, education, nature,intelligence, energy, nutrition, noise, trouble, employment,
三、許多名詞既是可數(shù)名詞也是不可數(shù)名詞，取決于說話者在特定的語境下想要表達的意思。同一個名詞在不同的語境下，表達不同的含義，導致不同的可數(shù)性。
1. We all like beer, so let’s order 3 beers. (3 bottles/glassesof beer)
2. Air is vital for life, but the air in this room isvery unpleasant.
3. Radiators should produce hear, but the heat from thatradiator is minimal.
4. This ceiling is made of glass(玻璃). We need four wineglasses.（玻璃杯）
當一個名詞表示抽象的，總稱的概念（abstract or generalizingvalue）時，一般作為不可數(shù)名詞。當他具有具體的、特定的含義(restricted value)時，通常為可數(shù)名詞。
四、不可數(shù)名詞的度量
不可數(shù)名詞不和不定冠詞（a/an）和基數(shù)詞(one, two)連用，沒有復數(shù)形式。不可數(shù)名詞和特定的量詞連用。
a loaf of bread
a bar of soap/chocolate
a piece of information/news/luggage/furniture
