A comparative study of the two English versions is made to figure out how the two translators linguistically and culturally make adaptive selections in the process of translation of Lu Xun's stories—In other words, how the eco-environment has greatly influenced the two translators' decisions to make adaptations and choices in linguistic and cultural aspects.The thesis discovers that the eco-environment has greatly influenced the process of translating Lu Xun's stories into English and eco-translatology is feasible to analyze the two translations, that both the Yangs and Lovell have offered successful translations by making adaptive selections and selective transformations. Therefore, neither of the two translations is superior or inferior to one another in different translational eco- environments. Hopefully, the thesis may enrich current researches on the Yang's and Lovell's translations and may be useful for the further study of applying eco-translatology to studies on other translators and their works.展开更多
