尤金·奥尼尔在其戏剧创作中勇于探索,大胆实践,他不仅将传统的戏剧创作手法和现代主义创作手法相结合,而且还将小说创作技巧用于其戏剧创作之中。1920～1932年是奥尼尔创作的独特阶段,他将面具等现代主义表现手法融入其戏剧创作,因此,面具在其剧作中以不同的形式出现,如同镜子般反映和揭示了剧中人扭曲、变态而复杂的心路历程。 Eugene O’Neill has the courage to explore and bold practice in his dramatic creation. He not only combines the traditional methods of drama creation with those of modernism, but also applies novelistic techniques to his dramatic writing. From 1920 to 1932 he was the unique stage of O’Neill’s creation. He integrated modernist techniques such as masks into his dramatic writing. Therefore, masks appear in different forms in his plays, mirroring and revealing distortions of people in the play, Metamorphosis and complex mental journey.
