规律——
在【I/We + 谓语动词 + （that）从句】句型中,反意问句与that从句保持一致.如：
I suppose you are not serious,are you?
I'm sure that you'll succeed,won't you?
I don't think that you can do it,can you?（请注意否定转移）
I think that he has done his best,hasn't he?
We don't believe that the news is true,is it?（请注意否定转移）
I have been told that you are going to start your own online business,aren't you?
注意——
任何稍微不符合此句型特征的句子,都不遵循此规则.如：
He never said she would come,did he?（主句主语为He）
I have told you time and again that these rules should be strictly followed,haven't （主句谓语动词后多了间接宾语you）
之所以有此种规律,是因为此处的【I/We + 谓语动词】不承载实际内容,只起到句首发语、引起下文的作用.
