they don't believe the boy is lying,do they?这个句子的反问句是do they还是isn't he
答案：do they
1、反意疑问句的陈述部分为I(We) don’t think(believe,suppose,consider)+ that从句时,从句为否定意义,问句部分的动词和主语仍与that从句保持一致且用肯定式.如：
①I don’t think that you can do it,can you?(不用do )
②We don’t believe that the news is true,is it?(不用do we?)
2、反意疑问句的陈述部分为非第一人称主语+ think(believe,suppose,consider) + that从句时,问句部分的动词和主语与陈述部分的主句动词和主语保持一致.如：
①They all think that English is very important,don’t they?(不用isn’t it?)
②He didn’t think that the news was true,did he?(不用wasn’t/ was it?)
