compendium(学科)概要: 对某学科主要知识点及其细节的简要概述，syllabus提纲大纲: 用标题列出某课程学习内容，digest文摘: 将出处不同的文章摘录浓缩，为了快速方便阅读，survey纵览综述: 指简短但全面的概述，作为后续研究基础，sketch梗概速写: 指粗略概述，需要修改扩充，precis大意概述:  是对他人文章或作品的概述(而非自己的)


记忆方法: 1）首字母CSDSSP排序成PSCSDS平时尝试的事<==概述      "概"的本义是"量米粟的器具，是量米栗时刮平斗斛（hú）用的木板"。放在斗斛上刮平，不使过满。引申为一种衡量标准，现在有2个主要意思 1、某人的态度气势，如气概   2、包括，如概括一概概念大概   概述中的概指"大概=general,approximate"，这些词都来自"包括include"的意思

         2) 练习一下         科技论文的摘要用abstract: a brief statement of the main points in a thesis or paper，论文的开头是abstract，之后是introduction，再往后是正文，最后是conclusion。abstract和precis的区别是: abstract是对自己文章的概述，而precis是对"他人"文章的概述。precis介绍分析的内容更多，长度更长通常是原文的1/4，而abstract往往不超过10句话，简短得多。

         3）概述的意思是简要叙述mean a brief treatment of a subject or topic.   treat表示处理对待治疗叙述论述，和deal、handle是一组同义词，区别是treat通常接context上下文，如本例的brief简要的。如treat the subject realistically in the essay对散文主题如实地叙(论)述。
