few,a few,little ,a little的用法
few,a few,little,a little 虽然都表示“少”,但
1、few,a few修饰可数名词,little,a little修饰不可数名词.
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.
3、few修饰可数名词复数.few (= not many; hardly any)含否定意义；
4、a few (= some; several; a small number of) 含肯定意义.
5、not a few = no few = quite a few = a good few = many.
6、当 few受 every,last,past,next,some,very等词所修饰时,表示肯定意义,few之前不再有冠词.如：
In the last few minutes,he checked up his paper again.
It took us some few days to repair the machine.
They are very few in number.
There were too few of them.
He goes to see his grandma every few weeks.
7、little修饰不可数名词,表示“量”.
8、little含否定意义(反义词：much)；a little含肯定意义(反义词：none).
9、在非正式英语中,一般很少用little,常用not much,only a little来代替,如：
We haven’t got much money / time.
