A,一般第一人称反义疑问句用从句中的提问,陈述部分有have to +v.,疑问部分常用don't +主语

A.doesn't it
I think 句型的反意疑问句，要以从句的主语和助动词决定的。本句的主语是something,对应是it

选B 我认为
因为 i think是形式主语
something是主语

A啦。

选A。something是个代词，在这里做从句的主语，谓语动词用单数，反问式当然要用dosen't了。

选A ！！！I think...是主语，反疑疑问句应针对它来说，又因为后面陈述的为一项观点，故用单数形式--doesn't it ?
这也是常见的题型，例如 I think （that）the movie is moving,doesn't it? 等等等等。主要看是不是主从关系。

以I think that造句 that's what i think I also think that you I'm think about that. i think that that that that that is I think that I should change my I do that sometimes I think it I think that I am the I think so 和I think that的不同 I think that ...可以用什么代替 Do you think i was like that? I think that sounds so 中文啊用I think that造句,并翻译 i think造句用that,whether,if i think that's everything翻译 I do not think that的造句 I think that clouse怎么造句 I think that she is right.
