The Suzhounese polar question exhibits intervention effects, manifested by the linearity constraint barring anti-topical expressions against c-commanding the polar particle. This paper proposes to derive the intervention pattern from two assumptions. Namely, the polar operator is interpreted higher than the C-domain Q operator, and topics project a secondary illocutionary act independently of the primary act associated with the comment. I further show that the Suzhounese pattern is linked to linearity constraints elsewhere (e.g. in why-adjuncts) that crucially draw upon the exceptional wide scope of topics. I point out that the connections I have drawn motivate a novel class of scope effect that is distinct from the better understood focus-induced intervention.

苏州话极地问题的干预效果

苏州极地问题表现出干预效应，表现为线性约束禁止反对c-指挥极地粒子的反话题表达。本文建议从两个假设中得出干预模式。即，极性运算符的解释高于 C 域 Q 运算符，并且主题投射独立于与评论相关的主要行为的次要言外行为。我进一步表明，苏州模式与其他地方的线性约束有关（例如为什么-附件），它们关键地利用了异常广泛的主题。我指出，我所绘制的联系激发了一类新的范围效应，它不同于更好理解的焦点诱导干预。
