不可数名词没有复数形式， 要表示数量的多少时，其前可以加some, any等，作主语时，谓语动词要用单数形式。 用代词指代不可数名词时，用单数it。
不可数名词
粉末/颗粒类，如：flour（面粉），rice（米饭）
液体、气体等，如：water（水），air（空气）
语言、学科等，如：English（英语）,Chinese（汉语）
肉类，如：beef（牛肉），pork（猪肉）
油脂类，如：oil（油），butter（黄油）
一些抽象名词,如: knowledge (知识),friendship (友谊)
常见的不可数名词
我们应该如何来表达不可数名词的数量呢？
1. 用much, a lot of, some, little, a little
修饰不可数名词，表示量的多少。
1) We have much homework today.
2) There is a lot of water in the bottle.
3) She needs some help.
4) He has little time to finish his work.
5) I have a little juice in my glass.
不可数名词量的表达
2. 用数词+量词+of+不可数名词，表示具体的量。常用的量词有cup, glass, bottle, piece等。
1) I had a cup of tea yesterday.
2) She drinks a glass of milk every morning.
3) He opened two bottles of orange juice.
4) Can I have a piece of cake
量词既可与不可数名词连用，也可与可数名词连用。与可数名词连用时，可数名词必须用复数形式。如：two bags of apples
既可作可数名词又可作不可数名词的词
用法 例句
food 通常作不可数名词，表示食物的总称； 当表示特定种类的食品时，其复数形式为foods。 The food here is very delicious.
这儿的食物很美味。

2) Apples, bananas and pears are my favorite fruits.

ice-cream 表示“一份冰激凌”时，为可数名词时，用不定冠词修饰时，用an。 I like ice-cream.
我喜欢冰激凌。

请给我一份冰激凌。
