这是高中的语法,考查的是否定前置的疑问句形式,我先来说一下否定前置的情况吧：
1) 将think,believe,suppose,expect,fancy,imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式.
I don't think I know you.我想我并不认识你.
注意：若谓语动词为hope,宾语从句中的否定词不能转移.
I hope you weren't ill.我想你没有生病吧.
2) 将seem,appear 等后的从句的否定转移到前面.
It doesn't seem that they know where to go.
看来他们不知道往哪去.
3) 有时将动名词,介词短语或整个从句的否定转变为对谓语动词的否定.
I don't remember having ever seen such a man.
我记得从未见过这样一个人.(not否定动名词短语 having…)
It's not a place where anyone would expect to see strange characters on the street.
在这里,人们不会想到在街上会碰上陌生的人.
(anyone 作主语,从句中的谓语动词不能用否定形式.)
上面三种较常用!
然后我再说一下变换成疑问句的情况,
(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.
举个例子,she didn't think it was beautiful.did she?
d
选d，主语为I，并为否定，反义疑问句应转为肯定”are they"
D
i don't think they are right. 叫做否定前移，其实原句是：i think they aren't right.(这种反以疑问句要根据从句的主语和助动词来改)
类似的有I think/believe/guess 引导的宾语从句的反义疑问句
