汉语中的空成分与主题投射假设

汉语中有PRO(大空代词)、pro(小空代词)和变量(variable)。汉语主语位置的空成分为pro,空成分之所以在汉语中存在,是因为它具备Rizzi指出的两个允准条件:恰当的管辖者和恢复者;汉语中pro的恢复者是独立投射在句法结构中的主题,而主题则是通过特征承袭或拷贝的方式来恢复pro的。汉语宾语位置的空成分是变量,但变量的先行词不处于Comp位置,而是位于主题位置。

The empty categories in Chinese and hypothesis of topic projection

There is the distribution of PRO,pro,and variable in Chinese.We believe that the empty category at the site of subject position of finite construction is pro.The pro can be existent in Chinese Language is because of the fact that two licensing conditions mentioned by Rizzi(1986a) are satisfied: a governor and an identifier.In Chinese,the identifier of pro is the topic that is independently projected into the language structure.The related topic recovers pro by means of feature inheriting or copying.The empty category at object position of sentence is variable.But the antecedent of variable is not in position of Comp.It is in the position of topic.
