有一读者问：有这样一道填空题：
(1)He has few friends, _____?
如何填空？
应填has he, 因为few表否定。当陈述部分含有no, little, few, none, nobody, nothing, never, seldom, hardly, scarcely等否定词时，附加疑问句应用肯定结构，再如：
(2)He has no friends here, has he ?
(3)You know nothing about it, do you ?
(4)They have little money, have they ?
(5)I seldom get a letter from you，do I ?
但请注意，当陈述部分含有由表否定的前缀如un-, dis-, im-, in- 等构成的词，则不可将之作否定词对待，换言之，反意疑问句仍须用否定结构，如：
(6)It's unfair, isn't it ?
