Abstract: Doris Lessing, the Nobel Prize laureate in literature, constructed two different worlds in her science novel The Marriages Between Zones Three, Four and Five: one is an old and wicked world full of darkness, and the other is a new world full of imagination and hope. From the perspectives of utopia and dystopia, this paper aims to explore the author's utopian vision of a good society carried by the dystopian narration of a wicked world, thus revealing Lessing's concern and hope for human civilization and future world.
