本文通过对趋向动词“上”在系统内部各成员之间语义、句法特征等方面的比较,找出各自所具有的核心语义,并进一步以此确立判断趋向动词的五个检测条件。并通过“上”在古汉语、普通话和方言中的语义演变,区分出不同层次的趋向动词系统。 In this paper, the semantic and syntactic features of the verb “Shang ” in the system are compared to find out their core semantics, and then to establish the five testing conditions to judge the verb. Through the semantic evolution of “Shang” in ancient Chinese, Putonghua and dialect, we can distinguish different levels of tendency verbs.
