以《望岳》多个英译本分别适合不同读者群阅读需求为研究目的，立足《望岳》多个英译本，以原型-模型翻译理论为理论基础，引入其“适合”与“忠实”的翻译观和读者满足的观点，运用译文对比的研究方法，得出如下结论：许渊冲的译语文本适合满足专业读者的阅读需求；孙大雨的译语文本适合满足非专业成人读者的阅读需求；宇文所安的译语文本适合满足非专业儿童读者的阅读需求。因此，文章认为，诗歌翻译的译者只有运用合适的翻译策略“忠实”地将诗歌源语文本的写作特征翻译出来，“适合”不同分类的译语文本读者的阅读需求，不同版本才能因适合不同读者群阅读需求而具有共存性。

The different English versions of Wang Yue can meet the reading needs of different reader groups. Based on three English versions of Wang Yue, drawing on the Prototype-model Translation Theory, this paper introduces the translation concepts of "fitness" and "faithfulness" and readers' satisfaction, and reaches the following conclusions by using the research method of translation comparison: Xu Yuanchong's version can meet the reading needs of professional readers; Sun Dayu's version can meet the reading needs of non-professional adult readers; The version by Stephen Owen can meet the reading needs of non-professional children readers. Therefore, the article holds that only by using appropriate translation strategies to faithfully translate the writing features of the source text, and only by "adapting" to the reading needs of different reader groups, can different versions coexist because they fit the reading needs of different readers.
