【正确答案】正确答案：Allegory is a story or visual image with a second distinct meaning partially hidden behind its literal or visible meaning. The principal technique of allegory is personification, whereby abstract qualities are given human shape. An allegory may be conceived as a metaphor that is extended into a structured system. In written narrative, allegory involves a continuous parallel between two(or more)levels of meaning in a story, so that its persons and events correspond to their equivalents in a system of ideas or a chain of events external to the tale: each character and episode in John Bunyan" s The Pilgrim" s Progress, for example, embodies an idea within a pre-existing Puritan doctrine of salvation. Allegories are often moral, religious, or political.
