few 的用法说明
1. 比较 few 和 a few：两者均表示复数意义，few 表示数量很少或几乎没有，强调“少”，含有否定意义：a few 表示数量虽然少但毕竟还有，强调“有”，含有肯定意义。比较：
His theory is very difficult, and few people understandit. 他的理论很深奥，没有几个能懂。
His theory is very difficult, but a fewpeople understandit. 他的理论很深奥，但是有些人懂。
2. 一般说来，在 only, still, quite, not 等词之后通常用带有不定冠词的 a few, 而在 very, some, the, no, so, too 等词之后通常用不带冠词的 few。如：
only a few students passed the exam. 只有几个学生考及格。
Very few people understand what he said. 几乎没什么人懂他的话。
【注】可说 very few 或 a very few, 但不能说 very a few。
3. 其比较级和最高级分别为 fewer, fewest。如；
Who has the fewestmistakes? 谁的错误最少?
You ought to smoke fewercigarettes and drink less beer. 你应该少抽烟，少喝啤酒。
4. 用作形容词，其后可直接跟名词，无需用 of, 但是若其后名词之前有限定词修饰或者是代词或从句等，则必须要用介词 of。如：
Few of them know this. 他们当中没几个人知道这一点。
A few ofthese books are mine. 这些书当中有几本是我的。
5. a man [person] of few words 是习词，其中的 few 前不用冠词或其它限定词。
