"I used to think the place my parents lived was boring."的附加问句是什么?是和主句一致还是和从句一致?

与从句一致
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.1.I think that he has done his best, hasn't he?
2.We think that English is very useful, isn't it?
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。
eg.1.I don't think that you can do it, can you?
2.We don't believe that the news is true, is it?
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.1.They all think that English is very useful, don't they?
2.He didn't think that the news is true, did he?

wasn't it？

如果主句是I think(suppsoe/ am sure...) 等， 要和从句的主谓语保持对应关系
