This paper attempts to study those typical texts in detail,on the basis of the in-depth analysis of the narrative art and techniques of the 1940's narrative poems,mainly from four aspects:the lyric narration,imagery narration, dramatic narration,"moledicized" narration,so as to explore and appraise their historical contribution,values,functions and limitations in the modem poem history.In the narrative poems in the 1940s,the technique of"lyric narration" is embodied mainly in the high degree of artistic integration of "felling" and "polt".The lyricism is fully embodied in both structure and language,and generally through two ways:the lyricism of the dramatis personae and the lyricism of relaters or poet himselfThe narrative poets in 1940s have further developed the "mood" type of narrative poems(a kind of structure model of the modem narrative poem)which was created by predecessors.

本文试图在对有代表性的文本进行细致研读的基础上，对40年代叙事长诗的叙事艺术与策略进行深入剖析，主要从抒情化叙事、意象化叙事、戏剧化叙事、谣曲化叙事四个层面展开，以发掘、评判其在现代诗歌史上的历史贡献、价值、功能及局限等。40年代叙事长诗中的&抒情化叙事&策略主要体现于&情&与&事&的高度艺术融合，抒情形态表现在抒情结构与抒情语言方面；其抒情策略大体有两种方式：一是诗中人物的自我抒情，一是诗人自己或叙述人的抒情。40年代叙事诗人进一步发展了前人创造的&情绪型&叙事诗这种现代叙事诗的结构模式。
