若要比较两件份量不相等的事物，我们会用到这样的句型：
表达分量的的形容词 +（名词）+ than
要用哪一个分量形容词，取决于比较的名词是可数还是不可数。
可数名词
若名词是可数的，就要用 more 和 fewer。要注意，当比较的事物已经很明确，就可以省略不再提。下面最后一个例句针对此情况示范。
举例
- They have more children than we do.
- We have more customers than they do.
- Tom has fewer books than Jane.
- There are fewer houses in his village than in mine.
- You know more people than I do.
- I have visited the States more times than he has.
- I have three brothers. That's more than you have.（由第一个句子可知，后面要比较的是「brothers」）
不可数名词
若名词是不可数的，就用 more 或 less。要注意，当比较的事物已经很明确，就可以省略不再提。下面最后一个例句针对此情况示范。
举例
- John eats more food than Peter.
- Jim has less patience than Sam.
- You've heard more news than I have.
- He's had more success than his brother has.
- They've got less water than we have.
- I'm not hungry at all. I've had more than I want.（由第一个句子可知，后面要比较的是「food」）
