标题要幽默风趣
新闻报道的结构一般分为四个部分：(一)标题、(二)导语、(三)主体、(四)结语。标题是新闻的题目，是编辑对最有新闻价值内容的浓缩、概括、提炼和再创造。撰写标题是为了撷取新闻要点、诠释新闻意义、吸引读者阅读。在今天繁忙的现代社会中，报纸的读者大多是标题浏览者。导语是消息开头的第一段或第一句话，它扼要地揭示出消息的核心内容。主体是消息的主要部分，它用充足的事实表现主题，是对导语内容的进一步开展和阐释。新闻报道的结语一般是最后一句话或者一段话，通常对全文内容作概括性的总结，或对新闻事件的发展趋势作出预测。有时，作者根据报道的事实在结语中提出令人深思的问题。
一般来说，标题、导语和主体是构成新闻报道的必不可少的三部分。可根据新闻报道的内容而确定是否要结语或其它内容(如事件和历史背景等)，有时，还可将它们暗含在主体中。
在写新闻报道时，首先要注意新闻的标题具有语言幽默风趣的特点，有较强的吸引力。同时，写作依据的材料要充分，要用事实来说话，语言力求简洁。最后，报道中要有亮点，能引人深思或能让人产生强烈的兴趣。
