线索在写作中扮演着重要的角色，它们是故事的驱动力和情节的支撑点。线索可以是一个人物的行为举止，也可以是一个物品的出现，甚至是一个细微的提示。通过合理布置线索，作者可以引导读者进入故事情节，增强读者的阅读体验。同时，线索也是推动故事发展的关键因素，它们可以让故事更加紧凑、有趣、引人入胜。

The role of clues in writing is significant, as they are the driving force of the story and the support of the plot. Clues can be a character's behavior or an object's appearance, or even a subtle hint. By arranging clues logically, the author can guide the reader into the story and enhance the reader's reading experience. At the same time, clues are also critical factors that push the story forward, making it more compact, interesting, and engaging.
