概要是一种对原始文献或文章的基本内容进行浓缩的语义连贯的短文。读者在正确理解文章的基础上， 在不改变原文中心思想、体裁和结构的前提下，用简明、精练的语句高度浓缩文章的主要内容和观点，写出一篇内容概要。
N details——抓住主旨大意，省去细节信息。N examples——抓住主题要点，省去举例说明。N repetitin——抓住文本主线，省去重复信息。N cmments——抓住作者意图，不加任何评论。N cpying——抓住关键信息，巧妙同义转换。

1．读：细读原文材料，准确理解原文(1)理解作者的意图、观点和态度；(2)理解文章的基本结构；(3)理解主旨和要义。2．思：确定大纲框架，盘点要点信息发现问题：陈述是什么问题——是什么(what)?分析问题：原因1：……——为什么(why)?原因2：……原因 3：……解决问题：陈述怎么来解决这个问题——怎么办(hw)?
