Grammar
量词（Quantifiers）
一、核心概念
量词用于表示名词的数量或程度。选择哪个量词取决于名词的可数性（可数/不可数）以及数量的多少（少量/大量）。
教材定义：
Use a little to describe a small amount of something you cannot count, such as energy.
（用 a little 描述不可数名词的小量，如 energy。）
Use a few to describe a small amount of something you can count, such as cars.
（用 a few 描述可数名词的小量，如 cars。）
Use a lot of or lots of to describe a big amount of something we can or cannot count.
（用 a lot of 或 lots of 描述大量，可数/不可数名词均可。）
教材例句：
Hector uses a little energy.（Hector 用了一点能源。——不可数，少量）
There were only a few cars on the road.（路上只有几辆车。——可数，少量）
Mr. Big uses a lot of energy.（Mr. Big 用了很多能源。——不可数，大量）
There were lots of cars in the traffic jam.（交通堵塞中有很多车。——可数，大量）
二、量词分类表
量词 用法 含义 名词类型
a little 少量 一点儿 不可数名词
a few 少量 几个 可数名词（复数）
a lot of / lots of 大量 很多 可数/不可数均可
some（扩展） 一些 一些 可数/不可数均可（肯定句）
any（扩展） 一些 一些 可数/不可数均可（疑问/否定句）
much（扩展） 大量 很多 不可数名词（疑问/否定句）
many（扩展） 大量 很多 可数名词（疑问/否定句）
注意：a little 和 a few 强调“少”，但语气中性或积极（“虽然少，但还是有一些”）。如果想强调“几乎没有”，用 little 或 few（不带 a）。
三、可数名词与不可数名词的区分
1. 可数名词（Countable Nouns）
可以用数字数出来的名词，有单数和复数形式。
可数名词 例句
car → cars a few cars / a lot of cars
book → books a few books / lots of books
apple → apples a few apples / a lot of apples
student → students a few students / lots of students
2. 不可数名词（Uncountable Nouns）
不能用数字数出来的名词，没有复数形式（通常用单数）。
不可数名词 例句
energy a little energy / a lot of energy
water a little water / lots of water
money a little money / a lot of money
information a little information / a lot of information
