有时,附加疑问句和陈述部分是非反意的,即陈述部分和疑问部分都是肯定或都是否定.这种疑问句有人称为“共感疑问句”,主要用来表示惊奇、怀疑、反感、讽刺、愤怒、威胁等感情色彩,陈述部分前常有so,oh等词.初学者不宜模仿.
So you are a seaman,are you?Well,I think you are nothing…
你是水手?你是吗?哼,我看你什么都不是……
You mustn’t listen to his story.Oh,I mustn’t,mustn’t

B should not=不应该
can not=不能
must not=禁止
need not=不需要
should not最合适，通常对于you must not这种责备成分的句子，回答应该是should not，表示自己不应该，暗示知道自己做错了
