Abstract This manuscript presents a dependency grammar (DG) theory of answer fragments. The ellipsis mechanism implicated in answer fragments is called fragment ellipsis. The potential of a DG account based on the catena unit is probed, but found to be insufficient because it fails to account for certain cases involving in-situ focusing, e.g. Institutional what is hindering progress? – Authority. Therefore, an alternative account is produced, one that identifies four constraints on answer fragments, two that pertain to the elided material and two that pertain to the remnants that survive ellipsis. These four constraints then predict the shape of answer fragments to a large extent.

答案片段

摘要该手稿提出了答案片段的依存语法（DG）理论。包含在答案片段中的省略号机制称为片段省略号。已探究了基于链结单位的DG帐户的潜力，但由于它无法解决涉及现场集中的某些情况（例如，机构在阻碍进展）的原因而被发现是不足的。–权限。因此，产生了一个备选帐户，一个帐户确定了对答案片段的四个限制，两个帐户与被删减的材料有关，另外两个帐户与省略号仍然存在。然后，这四个约束条件将在很大程度上预测答案片段的形状。
