一、若反意疑问句的陈述部分为:
I(we) think(believe,suppose,consider)+that从句时,问句部分的助动词和主语与that从句内的动词和主语保持一致。
eg.I think that he has done his best,hasn't he?
二、若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,问句部分的助动词和主语仍与that从句保持一致,用肯定形式。(也就是否定前移,反义疑问句用肯定形式)
eg.I don't think that you can do it,can you?
三、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,问句部分的助动词和主语与陈述部分的助动词和主语保持一致。
eg.They all think that English is very useful,don't they?
