题目

He thinks his aunt is right.(改为反意疑问句） He thinks his aunt is right.____ ____?
我认为应该是：isn't she 是对aunt来做答,并且是否定的,但是正确答案是doesn't he,请问为什么用doesn't 而不是isn't
刚才有人回答对he think提的反意疑问,所以是doesn't he,这个我能理解,
可是我看到一个规则,就是I think/know/believe/guess/等词汇,要根据后面的that从句来形成反意疑问句的,还举了三个例子,我就是根据 这个两个例子来做的上面这道题,
例1：I know that you don't want to hurt me.do you?
例2：I believe that he will try his best.won't he
例3：I don't think that we can spend so much money on clothes,can we?
我想问到底是对think提反意疑问,还是对从句提反意疑问?

答案

含有think,believe,suppose,imagine,expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时,视情况不同有两种不同的构成方式.
(1.)当主句的主语为第一人称时,其后的简短问句应与从句相一致.例如：
I expect our English teacher will be back this weekend,won't she/he?
We suppose you have finished the project,haven't you?
值得注意的是,当这些动词后接的宾语从句的否定转移到主句时,其仍属否定句,故其后的简短问句应用肯定式,而非否定式.
例如：I don't believe that he can translate this book,can he?We don't imagine the twins have arrived,have they?
此类句子的回答同"前否后肯"型反意疑问句一样,如上述后一个句子,若双胞胎已经到了,则回答为"Yes,they have."；若尚未到达,使用"No,they haven't.".
(2).当主句的主语为第二、三人称时,其后的简短问句则应与主句相一致（此时,否定只看主句,与从句无关...）.
例如：Your sister supposes she needs no help,doesn't she?You thought they could have completed the project,didn't you?They don't believe she's an engineer,do they?
She doesn't expect that we are coming so soon,does she?
(3)但如果主句的时态是过去时等等,疑问句应和主句的人称时态保持一致.
