what nice food,it?反疑问句填什么?what nice food,it?what nice food,____it?为什么填isn't?

问题描述:

what nice food,it?反疑问句填什么?
what nice food,it?
what nice food,____it?
为什么填isn't?

isn"t .....

如果前半句是否定,后面反意疑问就用肯定.
同理,如果前面是肯定,后面就要用否定.
所以应该填,isn't it
很明显啦,反意疑问,疑问的部分,要跟前面分句相反意思,这还要怎样解释才明白呢。

实际上此句有省略.说全了应为:What nice food it is,isn't it?明白了吧?
