专 题 突 破 第 二 部 分 专题六　书面表达 第 3 讲　说明文 一般说来，事物说明文就是对具体事物进行说明或介绍，使读者了解和认识事物的特征，透过现象认识本质。其基本特点是：层次清晰，条理分明，语言简洁而逻辑性强。要 “ 明明白白 ” 地写好一篇事物说明文，准确地传递作者想要说明的信息，在写作中要注意以下几点： 1 ．明确写作重点，突出语言特色：在写作时要抓住写作对象的本质或主要特征，选用准确、简明的语言，精当地对其说明。有时为了把文章写得通俗易懂、生动活泼可以根据需要运用打比方、类比等修辞手段。 2 ．选好说明顺序，用好说明方法：根据说明对象的不同灵活安排，运用时间、空间、逻辑等写作顺序，力求做到解说清楚、条理分明。另外，根据实际需要合理使用说明方法，突出说明对象的特征，努力达到 “ 复杂事物简单化、抽象事物直观化、枯燥事物生动化 ” 的效果。在写作中可灵活选用下定义、例证法、分类法、比较法、因果分析法、列数字、打比方等说明方法。 一、表示原因 There are three reasons for this.
