什么是论文前言 (Introduction)
论文的前言(Introduction)是文章的开篇部分,其主要目的是为读者提供研究背景、阐述研究问题的重要性,并引出研究目的和主要论点。一个清晰有力的前言能够吸引读者继续阅读全文。
前言的基本结构
一个标准的英文论文前言通常包含以下几个部分:
- 背景介绍 (Background):介绍研究领域的总体情况。
- 问题陈述 (Problem Statement):指出当前研究中存在的空白或问题。
- 研究目的 (Research Purpose):明确本文的研究目标。
- 论文结构 (Outline):简要介绍文章后续部分的安排(可选)。
常用表达方式
以下是一些在英文前言中常用的句型和表达:
• This paper aims to investigate/examine/explore...
• The purpose of this study is to...
• Recent research has shown that...
• Despite extensive studies on..., little is known about...
• The main objective of this paper is to...
• The purpose of this study is to...

写作注意事项

- 避免在前言中提供过多细节或结果,这些内容应放在后续章节。
- 使用正式、客观的学术语言。
示例段落
以下是一个简短的前言示例:
"In recent years, climate change has become a major concern for scientists and policymakers alike. While numerous studies have focused on the impact of rising temperatures on polar regions, less attention has been paid to tropical ecosystems. This paper aims to fill this gap by examining the effects of climate change on rainforest biodiversity in Southeast Asia. The study combines field observations with satellite data to provide a comprehensive analysis of species distribution changes over the past two decades."
