學術論文的引言（Introduction）往往是論文中最難寫的部分之一。
如果你閱讀大量文獻並總結你會發現，其實論文寫作是有套路和模板的，就像寫八股文一樣。行文邏輯和句型都有套路和模板。
論文的Introduction的基本要素及邏輯關係一般包括：
· 1 背景，背景和或論文重要性
· 2 簡要回顧相關的學術文獻
· 3 研究領域中的問題、爭議/空白
· 4 引出研究目的和研究問題或假設
· 5 簡要帶出研究設計和方法
· 6 解釋研究的意義或價值
· 7 定義某些關鍵術語
· 8 簡要介紹論文或報告的組織結構
下面給出每個要素的句型模板。因內容過多，今天主要分享強調研究/主題的重要性：<主題/研究對世界、社會的的重要性><主題對學科的重要性><主題的重要性（給定時間範圍）><主題的重要性:要解決的問題>句型模板。
