复合动词在日语学习中占有重要的地位,它们虽具有丰富的表现力和数量多等特点,但是对于日语学习者来说要学会正确掌握其语义和灵活应用有着相当的难度。本文将从认知语言学的角度出发,运用认知语言学的意象图式等理论成果,对日语动词的多义性以及复合动词的构成等方面进行分析。在本文中,通过分析日语动词「落とす」的多义性,找出其对复合动词「V+落とす」的语义影响规律,从而能够帮助日语学习者更好地掌握和使用日语复合动词。 Compound verbs play an important role in Japanese language learning. Although they are rich in expressiveness and quantity, compound verbs are quite difficult for Japanese learners to learn how to grasp their semantics and flexibility. In this paper, from the perspective of cognitive linguistics, this thesis analyzes the polysemy of Japanese verbs and the composition of compound verbs by using the theoretical results of cognitive linguistics such as image schema. In this paper, by analyzing the polysemy of the Japanese verb “落 と す”, we can find out its influence on the semantic meaning of the compound verb “V + と と す”, which can help Japanese learners to grasp and use Japanese compound verbs better.
