物质名词和抽象名词一般是不可数的,但在一定条件下这些不可数名词可转化为可数名词。
1. 物质名词和抽象名词用来表示个别、具体的事物时,一般是可数的,但意义发生了一定的变化,如:
There is a glass of red wine on the
table. (葡萄酒)
Two wines, please. (两杯葡萄酒)
Every girl loves beauty. (美丽)
He married a beauty. (美女)
2. 物质名词表示“各种、各类”概念时,一般是可数的,如:
teas in the mountains (山里的各种茶叶)
fruits in the store (店里的各种水果)
slight stomach pains (轻微的胃痛)
3. 抽象名词表示“某一种”或“某一方面”的概念时,也可以是可数的,如:
Knowledge is power.(知识)
The book tells us a knowledge of Africa.(非洲方面的知识)
She lives in luxury.(奢侈)
My salary is low, so I get few luxuries.(奢侈品)
