VOA一分钟英语：Fewer 和 less 应该用哪个？

量词 “fewer” 和 “less” 的含义相似，它们都可以用来谈论两个或两组事物中的一个或一组 “少一点，少一些”。什么时候用 “fewer”？什么时候用 “less”？
 
Hi, I'm Sam from BBC Learning English, and today we are going to look at the difference between lessand fewerwhen comparing things.
It's actually very simple – we usefewerwith countable nouns andlesswith uncountable nouns, but even native speakers get this wrong, so let's have a look at some examples:
I moved recently, and comparing my old area to my new neighbourhood, I can say:
There are fewerrestaurants and fewercafes.
And there islesstraffic andlesspollution.
'Cafes' and 'restaurants' are countable nouns – you can count them on your fingers, and you can make them plural – so we use fewer.
'Pollution' and 'traffic' are uncountable nouns – you can't count them on your fingers, and you can't make them plural – so we use less.
 
用法总结
1 “Fewer” 用来修饰可数名词。
There are fewerrestaurants and fewercafes.
 
2 “Less” 用来修饰不可数名词。
There islesstraffic andlesspollution.
