2. 文献综述与研究现状 (Literature Review)
简要回顾已有研究,指出当前研究的空白或不足。
"While numerous studies have examined the impact of temperature rise on crop yields, limited research has focused on the combined effects of heat stress and water scarcity in arid regions."
3. 研究问题与目的 (Research Problem and Objectives)
明确指出你的研究要解决的具体问题和研究目标。
"This study aims to investigate the synergistic effects of elevated temperatures and reduced precipitation on wheat production in semi-arid zones."
4. 研究方法简述 (Brief Methodology)
简要说明你采用的研究方法。
"Using a combination of field experiments and climate modeling, we analyze yield variations under different climate scenarios."
5. 论文结构预览 (Structure Overview)
简要介绍论文后续部分的组织结构。
"The remainder of this paper is organized as follows: Section 2 reviews relevant literature, Section 3 describes the methodology, Section 4 presents the results, and Section 5 discusses implications and concludes."

逻辑清晰
确保各部分之间有清晰的逻辑过渡,使用恰当的连接词(however, therefore, furthermore, in addition等)。
避免过度承诺
不要夸大你的研究发现,保持学术严谨性。
注意时态使用
- 背景介绍:通常使用现在时(如 "Climate change affects...")

完整范例
以下是一个简短的论文前言范例:
Artificial intelligence (AI) is transforming various sectors of society, from healthcare to transportation. While AI offers unprecedented opportunities for efficiency and innovation, it also raises significant ethical concerns regarding privacy, bias, and accountability. Although numerous frameworks have been proposed to address AI ethics, there is limited consensus on practical implementation strategies in organizational settings. This study aims to identify key challenges in implementing AI ethics guidelines in medium-sized technology companies and to develop a practical framework for ethical AI deployment. Through qualitative interviews with 15 technology managers, we analyze current practices and identify common barriers. The findings contribute to the growing body of knowledge on responsible AI and provide actionable recommendations for practitioners. The paper is structured as follows: Section 2 reviews literature on AI ethics, Section 3 describes the methodology, Section 4 presents results, and Section 5 discusses implications and limitations.
