句末代词的所指与位置及其对句子语势的影响

Designatum and Syntactic Position of Sentence Final Pronoun and Its Impact on Sentence Force

句末代词分为实指和虚指两类。本研究揭示虚指代词出现在句末位置时具有加强相应小句语势的功能。由于自身带有主观性特征[+ Subjectivity],因此出于核查相应[+ Subjectivity]特征的需要,相应句末虚指代词已由原先IP内的宾语位提升至了更高层的ForceP位。提升后的语迹为空,形式上不能被占据。而仍位于IP内的代词则不带主观性特征,语义上仍受到相应句内或句外成分的管辖。

Sentence final pronouns can be concrete or empty designata.This study proposes that pronouns of empty designata in the sentence final positions are used to strengthen the sentential force with the feature of subjectivity [+Subjectivity].Therefore,it is raised to ForceP in order to have the [+Subjectivity] feature checked.The trace left cannot be occupied by other elements.In contrast,the sentence final pronoun in IP has the [-Subjectivity] feature and thus remains in situ to be governed by corresponding sentential or contextual element.
