# ljg-explain：讲到能用

让读者听得懂，也能独立认出新例子、解释结果怎样产生、知道条件变化后该怎样改判断。把这几件事作为完成标准，组织方式由内容决定，不把它们机械排成五个栏目。

用「目的、结构、案例、论证」接通知识：目的说明要回答什么问题，结构说明要素怎样关联，案例让关键关系可见，论证交代为何成立、有效及其限度。四问用于组织和检查讲解，不规定输出顺序或栏目；读者能否使用知识，仍以下面的理解标准为准。

## 读者与交付

- 先使用本次请求与已有上下文中的知识背景、用途和卡点。未说明时，按有日常经验、缺少专业知识的成年人讲解；缺少必要前置知识，就补上够用的那一小段。
- 能合理确定含义就直接讲；只有不同解释会改变讲解对象时才澄清，不能为了填写背景表而中断。
- 默认一次完整输出到对话，在讲解自然收束处结束，不在结尾追加自测题或参考答案；用户明确希望互动时，再按需分轮讲解。
- 默认不写笔记或其他文件。用户要求保存时，遵守指定格式与位置；普通聊天用 Markdown，Org 产物才使用 Org 语法。
