/*
 * 岐黄天使学习助手 - 重要说明
 * 
 * 本工具设计理念：
 * 1. 学习辅助而非替代学习：帮助用户更好地学习，而不是替代学习过程
 * 2. 答案参考而非直接作答：提供参考答案供用户思考，不会自动选择答案
 * 3. 促进理解而非应付考试：鼓励用户理解知识点，而不是单纯应付考试
 * 
 * 功能说明：
 * - 题目识别：自动识别当前学习的题目
 * - 答案参考：从题库中查找相关题目的参考答案
 * - 学习提醒：在适当时机提醒用户复习和巩固
 * - 进度跟踪：帮助用户了解学习进度
 * 
 * 使用建议：
 * 1. 先尝试自己回答问题，再查看参考答案
 * 2. 对照参考答案分析自己的理解是否正确
 * 3. 对于错误的题目，建议查阅相关资料深入学习
 * 4. 定期复习，巩固所学知识
 * 
 * 免责声明：
 * - 本工具仅供学习参考，使用者应遵守相关平台的使用规则
 * - 开发者不对使用本工具产生的任何后果承担责任
 * - 建议将此工具用于学习复习，而非考试作弊
 * - 真正的学习需要理解和思考，工具只是辅助手段
