一篇好的文献综述应该批判性地评价以前的研究，而不是简单地总结之前的工作。
作者要指出以往作品的不足，以证明你的研究值得进一步研究和探讨。
在文献综述的最后，作者还需要说明你的研究是独特的，没有文献可以直接解决这个问题。解释你的研究的重要性及其对你所在领域知识体系的价值。
文献综述的结构
Introduction:
●定义topic,井提供一个合适的背景来回顾文献
●建立你的理由(郾观点-文献回顾.
●解释这-部分的组织架构(次序) ;
●说明文献回顾的范围，即哪些内容包括在内哪些内容不包括在内。
例如，如果你在回顾关于儿童肥胖的文献。你可能会这样说有大量关于普通人群肥胖趋势的研究。然而。由于这项研究的重点是儿童的肥胖，这些文献将不会被详细研究。
Main body:
●根据共同的主题组织和批判分析文献
●对你选择的主题与更广泛的E题领域之间的关系提供见解，例如儿童肥胖和一般肥胖之间的关系:
●从文献综述的general.更广泛的视角转向你研究的具体重点。
Conclusion:
●总结现有文献主体的重要方面:
●评价文献综述的现状:
●识别现有知识中的重大缺陷或gap;
●低述未来研究的范畴:
●将你的研究与现有知识联系起来。
文献综述撰写要点:
●它不是一个描述性的列表。
它不是一本书接一本书, 一篇接一篇文章的摘要。
●它不是关于你的主题所写的每一件事的调查
●它必须由一个指导概念来定义。即论文要研究的问题或研究目标。
●它必须告诉读者在你的研究领域里已经建立和形成了哪些知识和观点，并概述它们的优点和缺点.
