3.20 few, little, a few, a little
 
(a) few + 可数名词, (a) little + 不可数名词
 a few / a little 为肯定含义,还有一点
 few / little 为否定含义,没有多少了。
 He has a few friends.   他有几个朋友。
 He has few friends.    他几乎没有朋友。
 We still have a little time. 我们还有点时间。
 There is little time left.几乎没剩下什么时间了。

典型例题:
  Although he 's wealthy,he spends___ on clothes.
  A. little  B. few C. a little  D. a few
  答案: A. spend所指的是钱,不可数,只能用little或 a little. 本句为although引导的让步状语从句,由句意知后句为否定含义,因此应用little表示几乎不。
