新闻报道新闻报道属于应用文体裁。一般来说,新闻有六个要素,即人物(wh)、事件(what)、时间(when)、地点(where)、原因(why)和过程(hw)。如果把这六个要素串起来,就能简洁地概括出新闻报道的内容了。它一般分为四个部分:标题、导语、主体、结语。写新闻报道时,首先要有一个吸引人的标题,简洁且能概括中心大意,是对最有新闻价值内容的浓缩、概括和提炼。
导语是消息开头的第一段或第一句话,它简明扼要地揭示出报道的核心内容(包括时间、地点、人物和事件)。主体是导语之后的新闻展开,补充更加翔实的细节,使新闻报道内容更加充实。要尽可能地引例子、举事实、列数字等,以使新闻真实可信,并引起读者的兴趣。结语一般是最后一句话或者一段话,通常对全文内容进行概括性的总结或对新闻事件的发展趋势做出预测,往往要照应标题或文章的中心。
