高考英语一轮复习作文分类指导十一说明文写作课件新人教版

,说明文是以说明为主要表达方式，要求用简洁明了的语言来解说事物、阐明事理，从而给读者提供知识的一种文体。近几年高考说明文多数以图表、表格或文字的形式给出提示，并往往融合在应用文体中进行考查，一般分为：场所路线介绍；事物介绍；方式、方法或计划安排介绍三大类。写说明文宜采用三段式： 第一段：主要介绍要说明的对象及说明的目的； 第二段：说明事物的主要特征或做事情的方法步骤； 第三段：进行总结概括。时态通常用一般现在时。,写作时应遵循以下几个步骤： （1）仔细审题，明确说明对象，抓住要说明的事物或事理的主要特征。 （2）选择合理的说明顺序（时间顺序、空间顺序或逻辑顺序）分层次进行说明，注意条理清晰。 （3）选择恰当的说明方法，比如定义法、举例法、比较法和细节描述法等，不要遗漏主要内容。 （4）根据说明顺序及内容确定过渡词和恰当的句型结构。文字应客观、简洁、明了，不要追求华丽和加入太多个人观点。,说明“方位”常用语： .is located at the foot of/by the side of., to the east of.

Now more and more people use their own mobile phones to communicate and instead of writing on the paper they e-mail to each other on the computer.
