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？
不可数名词量的表达
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.
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。
frozen foods冷冻食品
用法 例句
fruit 表示水果的总称时，为不可数名词； 表示水果的种类时，是可数名词，其复数形式为fruits。 I eat some fruit every day.我每天都吃一些水果。
Apples, bananas and pears are my favorite fruits.苹果、香蕉和梨是我最喜欢的水果。
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。
Please give me an ice-cream.请给我一份冰激凌。
作可数名词的词义 作不可数名词的词义
chicken 鸡 鸡肉
glass 玻璃杯 玻璃
room 房间 空间
time 次； 回 时间
orange 橙子 橙汁
有些名词既可作可数名词，又可作不可数名词， 但词义不同。
有些名词既是可数名词，又是不可数名词，在不同语境中有不同用法。如很多表示蔬菜、动物等的名词， 一般来说是可数的，但是表示餐桌上的食品时， 就转换为不可数名词。
a salad of tomato salad
a chicken chicken
some oranges orange
an ice cream ice cream
一份番茄沙拉
