Mood at Syntax-Pragmatics Interface

本研究旨在探讨句法-语用界面的一个方面，特别关注语法范畴语气。我们认为，情态不对称（观察到不允许嵌入祈使句）可以从句法上用言外之力来捕捉。更具体地说，我们提出了一种限制性机制--言语行为复合，从而使两种不同的以言行事的力量在所谓的表征言语环境下整合成一种言语行为成为可能。据此可以预测，在相同的环境下，嵌入式小句中既可以出现祈使句，也可以出现词根句。事实上，这一预言得到了证实。

This research project explores an aspect of syntax-pragmatics interface, focusing in particular on a grammatical category mood. We have argued that modal asymmetry, where it is observed that embedded imperatives cannot be allowed, can be syntactically captured in terms of illocutionary force. More specifically, we have presented a restrictive mechanism"speech act compounding, thereby making it possible for two distinct illocutionary forces to be integrated into one single speech act under so-called Represented Speech environments. It is, then, predicted that root sentences as well as an imperative sentence can occur in embedded clauses under the same environment. The prediction was, in fact, borne out.
