Abstract: Beloved written by Toni Morrison is brimming with profound sense and tension which have been focused on by an increasing large number of scholars at home and abroad. The word “Tension” means the balance between at least two inconsistent literary factors which cannot be dispelled by their opposed relationships. Based on the sense of tension and previous studies, this thesis is about further exploring its tension in themes, characters, and aesthetics. The author employs many kinds of rhetoric, such as symbol, simile, personification and poetization, representing a new method of rhetoric and contributing to a unique “black” poetic impression, which makes the story not only have the charm of form, but the tension of its idea and spirit of nationality.
