(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。

固定搭配:

only a few (=few)　 not a few (=many)　 quite a few (=many)

many a (=many)

Many books were sold.

Many a book was sold.

卖出了许多书。
