few和a few的区别:few / a few用来修饰可数名词,few表示否定意义,没有,几乎没有,a few表示有肯定意思,有几个。
1. few的意思是"很少的...,几乎没有的...", 表示" 虽然有,但很少", 强调"少",表示否定的意思。
例句:There are few people in the room.
房间里没有几个人。(虽有但少)

2. a few的意思是"少数的...几个...,一些..."表示虽然少,但"还有",强调"有",表示肯定之意,两者之间的差别主要是主观上的,而不是实际数字上的差别。
例句:There are a few eggs in the basket.
篮子里有几个鸡蛋。
3. few作形容词用,都表示“几乎没有”,后面跟复数可数名词。
例句:He has few friends here, he feels lonely.
他在这里几乎没有朋友,他感到孤独。
4. a few 后加可数名词复数。
例句:I'm going to buy a few bananas.
我要去买几个香蕉。
5. not a few = no few = quite a few = a good few = many
例句:Now,the crowd outside his church includes teenage couples and not a few miniskirts.
现在,他教堂外边的人群包括青少年夫妻,不少人穿迷你短裙。
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。
例句:In thelast fewminutes, he checked up his paper again.
在最后的几分钟里,他又检查了一下他的论文。
