宾语从句变反义疑问句,对主句还是从句提问？

宾语从句变换为反意疑问句的规则：
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?
注意：记住前两者特殊情况，其他的遵照第三种变换即可。希望能够给你带来帮助！
