《从宜宾到重庆》是一篇选自电视系列片《话说长江》的解说词。解说诃,即口头解释说明的词。它是说明文的文艺性和形象性的发展.它与一般说明文相比,既有共性,又有个性。现以本文为例,谈谈解说词的一般特点.文字与被说明的图像相依相辅,互为补充,相得益彰,这是解说词最主要的特点。解说词有补充视觉的作用,它没有必要象一般说明文那样说明得 “From Yibin to Chongqing” is a commentary from a television series “Saying the Yangtze River.” Commentary 诃, the word spoken orally explained. It is a description of the literary and visual development of the text. Compared with the general exposition, it has both commonalities and personalities. Now take this article as an example to talk about the general characteristics of the narration word. The text and the illustrated image are complementary, complement each other and complement each other. This is the most important feature of the commentary. The commentary has the function of supplementing vision. It does not need to be described as a general exposition.
