However, when the subject of the statement part is I, and the predicate is think, believe, suppose, expect, etc., the additional question part often maintains a correspondence with the subject and predicate verb in the clause, but pay attention to the transfer of negation.

18. In colloquial and informal genres, in order to strengthen the tone, it is only to express some kind of emotion of surprise, doubt, disgust, sarcasm, etc., rather than to seek an answer, when the affirmation and negation of the two parts are the same. As:
