宾语从句的反义疑问句,应根据从句的主谓的,需要句子时态是一般现在时吗?

宾语从句的反意疑问句的对应规则：
一、若主句为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、若主句为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、若主句为非第一人称主语＋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?

that从句内的动词和主语保持一致,如果句子时态是一般现在时，那么反义疑问句就是一般现在时。
