题目：Update Semantics for Imperatives with Priorities
摘要： Imperatives occur ubiquitously in our social communications.
In real life we often get conflicting orders issued by di erent speakers
whose authorities are ranked. We propose a new update semantics to
interpret the meaning of imperatives with priorities and illustrate what
changes they bring about in the addressee's cognitive state. The general
properties of the semantics, as well as its core philosophical ideas are
discussed extensively in this talk.
