This study focuses on the semantic prosody of Chinese light verbs"Nong"and"Gao". Although both of them have thesame grammatical function as light verbs, they are distributed differently in contexts. The current study proposes that"Nong"and"Gao"are different in semantic prosody, in which the former tend to appear in negative constructions while the later denotes posi-tive meaning. This paper is going to contrast the their performances by corpus searching.
