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.
