Among them, theeffects from Madame Ratignolle and Madame Reisz are of great importance in the process of Edna's awakening and to her final sui-cide. This dissertation will see how Edna is affected by and distinguished from them, and get the conclusion that Edna fails being alife mediator by contrasting with the two women.展开更多
