在日语学习和日常会话中,我们经常会遇到「かなり」和「けっこう」这两个表示程度的词。经考察发现,两者均可表示“程度很高”。虽然其用法对于我国日语学习者来说比较简单,但是出错的情况也不少见。由于「かなり」和「けっこう」的词性和用法较多,本论文主要以其最容易让人混淆的副词和形容词的用法为主,试着进行分析和比较。 In Japanese learning and daily conversation, we often encounter the words “ka na ri” and “kedokugo”. After investigation, both can be said “very high ”. Although its usage is relatively simple for our Japanese learners, it is not uncommon for mistakes to be made. Because of the more part-of-speech and usage of “ka na ri” and “e ko ko u”, this essay mainly tries to analyze and compare the usage of adverbs and adjectives which are most confusing to people.
