学术论文的引言（Introduction）往往是论文中最难写的部分之一。
如果你阅读大量文献并总结你会发现，其实论文写作是有套路和模板的，就像写八股文一样。行文逻辑和句型都有套路和模板。
论文的Introduction的基本要素及逻辑关系一般包括：
· 1 背景，背景和或论文重要性
· 2 简要回顾相关的学术文献
· 3 研究领域中的问题、争议/空白
· 4 引出研究目的和研究问题或假设
· 5 简要带出研究设计和方法
· 6 解释研究的意义或价值
· 7 定义某些关键术语
· 8 简要介绍论文或报告的组织结构
下面给出每个要素的句型模板。因内容过多，今天主要分享强调研究/主题的重要性：<主题/研究对世界、社会的的重要性><主题对学科的重要性><主题的重要性（给定时间范围）><主题的重要性:要解决的问题>句型模板。
