2) 不可数名词
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
注意事项:
1.不可数名词没有复数变化,不能用A,AN,但可用THE,或不用冠词,如:bread is the usual breakfast.
2.虽然不可数名词没有复数变化,但量词超过一时要加复数。

3.有量词修饰时注意名词是否可数,不可数时用单数,可数时用复数,如:ten bags of rice---- ten baskets of eggs
