开头段的写作技巧
开头段是全文的引言，既要点题、表明观点，又要为中间核心段的具体论述做好铺垫但是一定要新颖、独特，切忌离题太远，内容空洞无物，讲了半天，读者还不知道你要说什么。因此，一篇好的文章开头一般具有以下几个特点。
一是新，即新颖，它可以是内容上的新颖也可以是形式上的新颖。
二是奇，就是奇特，通过超常规的东西来吸引读者。
三是险，指的是惊险，这特别表现在文艺作品的开头。
四是深，指深刻，要具有哲理深度或含蓄深邃。
五是美，指优美，特别体现在情感的抒发和风景的描绘上。
六是引人入胜，扣人心弦，尽可能吸引读者的注意力。尽管文章的开头可以各显神通。
七是简明扼要。
开头段的作用是表达观点、开启话题，为下文的论述作准备，因此，如果有要陈述的论据，务必要简单明晰，切中要害，切忌啰唆。
