Previous researches have shown that non-native Japanese learners believe it's unchallenging to be proficient in using passive sentences. On the contrary, passive sentences are tough to master, and learners are prone to make mistakes on them. This study aims to enhance intermediate-level Japanese learners' ability to apply passive sentences, we'll elaborate it in two methods. The first method emphasizes the literal meaning of passive sentences; the second method introduces story-telling and peer tasks. Based on our experimental test results, we found that the first method is effective in aiding learners to understand sentence structures better, while the second one helps them to apply passive sentences more accurately in situational conversations. However, these methods failed to meet our expectation on improving learners' capability to identify grammatical logics. In conclusion, to improve Japanese learners' ability to apply passive sentences, it is crucial to choose correct subjects and form grammatically logical sentences.
