- You can use numbers with them: one apple, two apples.

什么是不可数名词？
Uncountable nouns are for things we cannot count individually. These often include:
- Liquids: water, coffee, milk
- Materials: wood, metal, plastic
- Abstract ideas: information, advice, happiness
- Gases: air, oxygen
- Small particles: rice, sand, sugar
They usually only have a singular form and do not take a 或 an. We cannot use numbers directly with them. Instead, we use quantifiers like much, a little, some, any, a lot of.
How Do We Use Quantifiers with These Nouns?
Choosing the correct quantifier depends on whether the noun is countable or uncountable. Here are the main ones:
- Many: Used with countable nouns in plural. How many books do you have?
- Much: Used with uncountable nouns. How much money do you need?
- A lot of / Lots of: Can be used with both countable (plural) and uncountable nouns. This is very common in informal English. She has a lot of friends. / We have lots of work.
- Few / A few: Used with countable nouns in plural. Few people came. / I have a few questions.
- Little / A little: Used with uncountable nouns. There is little hope. / Can I have a little sugar?
- Some / Any: Used with both countable (plural) and uncountable nouns. Some is for positive statements and offers. Any is for questions and negative statements. I have some ideas. / Do you have any water? / I don’t have any money.
When Can Uncountable Nouns Become Countable?
Sometimes, an uncountable noun can be used in a countable way, but its meaning changes slightly. This is important for B2 learners.
- General vs. Specific Types: Coffee (uncountable, the drink) vs. two coffees (countable, two cups/orders of coffee).
- Abstract vs. Concrete Instance: Experience (uncountable, general knowledge) vs. an experience (countable, a specific event).
- Using Measuring Words: We can count uncountable nouns by using specific units or containers. For example, instead of two waters, we say two bottles of water 或 two glasses of water. Other examples include a slice of bread, a piece of advice, a carton of milk.
| Quantifier | Countable Nouns (Plural) | 不可数名词 |

西班牙语母语者常犯的错误
Spanish speakers often make mistakes with countable and uncountable nouns because some nouns are treated differently in English and Spanish.
- 添加 -s 对于不可数名词： In Spanish, nouns like ‘información’ or ‘consejo’ can sometimes be pluralized in a way that doesn’t directly translate to English. For example, you cannot say
informations或advices. The correct forms are information 和 advice. - 使用 many 与不可数名词搭配时： It’s incorrect to say
many money或many furniture. The correct forms are much money 和 much furniture （或 a lot of furniture). - 使用 a/an 与不可数名词搭配时： You cannot say
an advice或a bread. Instead, use a piece of advice 或 a slice of bread.
常见问题
What is the main difference between countable and uncountable nouns?
The main difference is that countable nouns refer to individual items you can count and pluralize (e.g., three apples), while uncountable nouns refer to things you cannot count individually and usually only have a singular form (e.g., some water).
Is ‘fruit’ countable or uncountable?
一般来说，, fruit is used as an uncountable noun in English when referring to fruit in general (e.g., Fruit is good for you.). However, when talking about different types of fruit, it can be countable (e.g., There are many exotic fruits in this market.).
How do I know if a noun is countable or uncountable?
A good test is to try to put a number in front of it or add an -s to make it plural. If it sounds natural (e.g., two chairs), it’s countable. If it doesn’t (e.g., two waters), it’s uncountable. For uncountable nouns, think about whether you need a measuring word like a piece of 或 a glass of.
