否定转移句的附加疑问句
I don't think you ever go to the market to buy food for the family, do you? 按照附加疑问句的使用规则，上句中的 do you? 应改为 do I? 请对比：You think it funny to plan a meeting like this, don't you?
你提到的第一个句子与第二个句子并不是相同的句型。第一个句子叫做否定转移句：从形式上看 not 是否定主句的，但实质上是否定 that 从句的。
I don't think he's serious. I think he isn't serious. 我认为他不是认真的。
否定转移句之后的附加疑问句应重复 that 从句中的主语和助动词,并把 that 从句看作是否定句:
-
I don't suppose he's serious, is he? 我认为他不是认真的,是不是呢?
-
I don't suppose you are serious, are you? 我认为你不是认真的,是不是?
-
I don't suppose he cares, does he? 我认为他不会介意的, 是吧?
-
I don't think this book is interesting, is it? 我认为这本书没有趣,是不是? (参见 transferred negation , tag questions )
