The character"lai"in the Shouxian dialect of Anhui is one of the progressive aspect markers.The study explores the syntactic combination of"lai"with different types of verbs based on the syntax-semantics interface.It founds that there are obvious combination restrictions between"lai"and state verbs,achievement verbs,and semelfactive verbs.The study believes that the[+duration]feature is the key to whether the verb can be matched with the progressive aspect marker"lai"in the Shouxian dialect.This study further shows that the study of syntax-semantics interface issues should not ignore the study of aktionsart and grammatical aspects,which is an important direction for explaining syntactic phe-nomena.
