a few后面加可数名词复数。例如，I stayed there a few days longer.我在那里多住了几天。
few、little区别
（1）few,a few是可数的,little,a little是不可数的。
（2）a few,a little含肯定意味，few,little含否定意味。
这里所谓的“肯定意味”和“否定意味”应该这样来理解：
同样是半杯水，口渴者会认为：There is little water in the glass.
而不口渴的人则会认为：There is a little water in the glass.
a few例句
I made a few phone calls
我打了几个电话。
We had a few drinks afterwards
后来我们喝了几杯。
