Talking about quantities
We can use a lot of, a little, a few, enough，much, many and no to talk about quantities.
Du Yun’s family were caught by a sudden storm when they were on holiday. Read how they check the quantities of water and drinks in their beach house. Pay attention to the words in bold.
Mum: How many bottles of milk do we have
Du Yun: We don't have many bottles of milk. Only
two. But we have a few cartons of yogurt.
Mum: How much water do we have
Du Yun: We don't have enough water. We've only got
two 5-litre bottles.
Dad: Oh, I just remembered! We've got a lot of fruit
juice in the car. I’ll go and get it when it stops
raining.
We use how much a little and much with uncountable nouns.
How much water is there in this bottle
We use how many, a few and many with countable nouns.
How many bottles of water are there in the fridge
We use a lot of、enough and no with both countable and uncountable nouns.
There is a lot of / enough / a little / not much / no water in this bottle.
There are a lot of / enough / a few / many / no bottles of water in the fridge.
We usually use a lol of in positive sentences, much in negative sentences and many in both.
He always puts a lot of sugar in his coffee.
There is not much fresh water on Earth.
There are (not) many new words in the article.
在肯定句中用a lot of, 在否定句中使用much,而 many 既可用于肯定句也可用于否定句。
He always puts a lot of sugar in his coffee.他总是在咖啡 中放许多糖。
There is not much fresh water on Earth.地球上淡水不多。
There are (not) many new words in the article.
这篇文章中 (没)有很多新单词。
英语一些量词的用法
1. many/much表数量的“多”
many +[C], much + [U]
There are many students in his school.
Tony ate much bread this morning before going to school.
*在非正式文体中，疑问句或者否定句中常使用
much来修饰不可数名词； 使用many来修饰复数可数名词。
Do you have much bread
I don’t have much bread.
Are there many apples in the basket
2. a lot of / lots of 表示“许多”，既可修饰可数名词，也可修饰不可数名词,一般不用于否定句。书面语用a lot of较多,口语用lots of较多.
There are a lot of (many/lots of) people in the park every morning.
We need a lot of (much/lots of) time to check the answers.
*在非正式文体中，肯定句常用a lot of而不用much;
I have much bread.(语法无错，但是古怪)
I have a lot of bread.(常见的用法)
3. few / a few / little / a little
含义用法 表示肯定 表示否定
用于可数名词 a few虽少，但有几个 few不多，几乎没有
用于不可数名词 a little，虽少，但有一点 little不多，没有什么
only a little=not much; only a few=not many
quite a little=much=a lot of
quite a few=many=a lot of
I have a little milk left.=I don’t have much milk.
I have a few friends.=I do not have many friends.
a little和little也可以用作副词，a little表示“有点，稍微”，little表示“很少”。
I’m a little hungry. (修饰形容词hungry)
Let him sleep a little. (修饰动词sleep)
Linda is a little taller than I. (修饰比较级)
He slept very little/too little last night.
4. no / none / enough 用法
no+可数/不可数名词= not any/not a
I have no pen. =I have not a pen.
There is no milk in the cup.=There is not any milk in the cup.
none后面不直接加名词, 可指可数/不可数名词=not any / not one*可以用none来回答由How many或者How much引导的特殊疑问句；
--How many people came to the party
--(There are) none.
---Is there any milk left ---No, none at all.
None of us is (are) right.
enough＋可数/不可数名词 adj. 足够的
Don’t worry. There is enough food for all.
I haven’t got enough time for it.
*enough在句中的位置：enough修饰名词，要放在名词前；enough修饰形容词/副词/动词，放在这些词之后；
They don’t have enough time/apples.(+n.)
He’s not kind enough.(+adj.)
You don’t exercise enough.(+v.)
Jim can’t run quickly enough.(+adv.)
5. how many /how much用来询问数量的“多少”。
How many+可数名词数量
How much+不可数名词数量
How many teachers are there in your school How many bags of rice are there in the box
How much water does your body need every day
6. too much, too many, too little, too few
too much 表示数量之 “太多 ”，后跟不可数名词，反义为“too little ”(太少)；这两个短语也可修饰动词。
用too many +可数名词，反义为too few (太少)+可数名词。
He eats too much meat. It’s bad for his health.
too much，much too
too much的中心词是“much”,后面跟不可数名词，意思是“太多的……”；
too是用来加强much语气的。
much too中的中心词是“too”，后面跟形容词或副词，意思是“非常，太”；much是用来加强too的语气的。
e.g. There is too much snow and ice. It’s much too cold.
7. plenty of + 可数 / 不可数名词, 表示“充分, 大量”。
There are plenty of men out of work.
We have plenty of time to finish the job.
描述数量 提问数量
修饰可数名词 (not) many， a great / large / small number of，a few，few， too many，too few how many
修饰不可数名词 (not) much，a great deal of，a great / large / small amount of，a little，little，too much，too little how much
既可修饰可数名词， 也可修饰不可数名词 a lot of，lots of，plenty of，some， any，no，(not) enough
