As a Nobel Prize laureate ，John Steinbeck is among the most enduring writers that America has ever had． With a keen eye and unswerving dedication to the experimentation of writing ，he has completed many works of universal concerns． Al- though his works still enjoy great popularity among readers ，they have long been regarded as examples of the “Leftist Literature ” arising from the Great Depression． During his life time ，Steinbeck has rarely received due critical attention ，and the studies of his works have been apparently inadequate compared with those of his contemporaries． A careful reading of his major novels ，howev- er ，reveals that apart from the historical significance in representing the ordeal and dignity of mankind ，Steinbeck ’s fiction has also achieved great accomplishment in fictional narrative． The mythological narration structure ，flexible point of view ，varied nar- ration modes ，together with poetic language ，have not only strengthened the aesthetic appeal of the major historical events in his fiction ，but also expanded the sphere of modern American novel． The success of Steinbeck ’s narrative strategy ，to a large extent ， lies in the integration of mythological naturalism with poetic language．
