题目内容：

She had little to eat,_______ she?
填“had”不对吗?little是否定的吧

优质解答

She had little to eat,__did_ __she___?
little 本身有否定意味
参考：
（1）当陈述部分有never,seldom,hardly,few,little,barely,scarcely,nothing,none,rarely 等否定意义的词汇时,后面的反意疑问句则为肯定形式：
There are few apples in the basket,are there?
He can hardly swim,can he?
They seldom come late,do they?
（2）当陈述部分含有否定意思的词是unhappy,dislike,unfriendly等含有否定词缀的派生词,也就是有un-前缀、-less后缀等含有词缀而意思否定的词,当做肯定句处理,疑问部分要用否定形式.如：　　He looks unhappy,doesn'the?他看上去不高兴,不是吗?
The girl dislikes history,doesn'tshe?这女孩不喜欢历史,不是吗?
有less,fewer等词视为肯定词,疑问部分用否定形式.
如：　There will be less pollution,won't there?
