《宇宙的边疆》是一部电视片的解说词，它节 选自卡尔•萨根的作品《宇宙》。
解说词的文体特点 
解说词是对展览、实物、影视、图片、名胜古迹和历史文物进行解释说明的一种文体。它通过对事物的准确描叙，词语的渲染，来感染观众或听众，使其了解事物的来龙去脉和意义，收到很好的宣传效果。
解说词根据被解释的对象可分为文学性解说词和平实性解说词两种。用于参观浏览的导游解说词，用于电影电视风光片的解说词，多用文学、散文手法，既抒情又有解释说明，语言绚丽多彩，情感真挚浓郁。用于生产成就的参观展览的解说词，科普影片、新闻纪念片的解说词，如历史文献纪录片《邓小平》的解说词，则运用朴实真挚的语言，介绍邓小平光辉伟大的一生。 
解说词有补充视觉和听觉的作用，具有以下特点： 
（1）语言通俗、平易，读起来顺口，听起来顺耳（通俗的语言）。因为解说词是对形象画面的补充，是通过语言表达来宣传和教育群众的。 
（2）紧扣实物和形象进行解说（明确的对象，清晰的顺序）

。实物和形象是解说词写作的依据，忠实于实物和形象是解说词写作的基本原则。围绕实物、形象这一中心点，安排结构，组织段落，绝不能游离于具体的解说对象。 
（3）注重文艺性。解说词不是空洞的说教，必须通过形象的语言实物进行描绘，就像报告文学是报告事实和文艺创作一样，解说词是说明和描写的结合，具有文学伤口的一些特点，好的解说词是一支感人的歌，一首动人的诗。
