This article looks at constructions involving optional movement of contrastive foci and argues that this type of reordering cannot be accounted for by assuming that it is driven by a syntactic feature. I maintain that an interface‐based approach that rests on the principles of economy fares better at capturing the data, as it accounts not only for optionality of contrastive‐focus movement, which is found in a wide variety of languages, but also for multiple landing sites for contrastive‐focus movement, which are found in scrambling languages, such as Russian.

运动的选择性

本文研究了涉及对比焦点的可选运动的构造，并认为不能通过假设它是由句法特征来解释这种重新排序。我认为，基于经济原理的基于接口的方法更适合捕获数据，因为它不仅考虑了对比焦点移动的可选性（可以在多种语言中找到），而且可以实现多次着陆对比焦点移动的站点，这些站点以乱语（例如俄语）找到。
