Title: The Impact of Social Media on Adolescents' Mental Health
Abstract:
This paper investigates the impact of social media on adolescents' mental health. With the increasing popularity of social media platforms, concerns have been raised about their potential negative effects on mental well-being, particularly among adolescents. This study aims to explore the relationship between social media use and mental health outcomes in this age group.
The research adopts a quantitative approach, collecting data from a sample of 500 adolescents aged 13 to 18 years. Participants completed self-report questionnaires measuring their social media use and mental health status. The questionnaires included validated scales such as the Social Media Use Scale and the Depression and Anxiety Scale for Adolescents.
The results indicate a significant association between social media use and mental health outcomes. Adolescents who reported higher levels of social media use also reported higher levels of depression and anxiety symptoms. Furthermore, the study found that the frequency of social media use and the duration of use were positively correlated with the severity of mental health symptoms.
These findings highlight the need for further research on the complex relationship between social media use and mental health among adolescents. It is crucial for parents, educators, and mental health professionals to be aware of the potential risks associated with excessive social media use and to develop strategies to promote healthy digital habits.
Keywords: social media, adolescents, mental health, depression, anxiety

Title: The Impact of Renewable Energy on Sustainable Development
Abstract:
This paper examines the impact of renewable energy on sustainable development. As the world faces the challenges of climate change and increasing energy demands, the transition to renewable sources of energy has become a global priority. This study aims to explore the potential benefits of renewable energy in achieving sustainable development goals.
Through a comprehensive literature review, this research examines the environmental, social, and economic dimensions of renewable energy. The findings indicate that renewable energy sources, such as solar and wind power, have the potential to reduce greenhouse gas emissions, mitigate climate change, and improve air quality. Moreover, the adoption of renewable energy technologies can create job opportunities, stimulate economic growth, and enhance energy security.
Case studies from different countries and regions are analyzed to provide empirical evidence of the positive impact of renewable energy on sustainable development. These case studies include successful renewable energy projects in Germany, Denmark, and Costa Rica, which have demonstrated the feasibility and benefits of transitioning to a sustainable energy system.
The study concludes that renewable energy plays a crucial role in achieving sustainable development targets. Policymakers, businesses, and individuals should prioritize the development and utilization of renewable energy sources to promote a more sustainable and resilient future. However, challenges such as the intermittency of renewable energy supply and the need for supportive policies and investments should be addressed to maximize the potential benefits.
Keywords: renewable energy, sustainable development, climate change, energy transition, case studies

英文论文摘要格式
摘要在一篇论文中的位置举足轻重。它可以快速简洁地将作者的作文意图传达给读者。以下小编就为大家介绍英文论文摘要格式以及书写方法，一起来阅读学习吧!
一、英文论文摘要的种类
摘要主要有三种：学术论文摘要，学术会议摘要及由专门摘要撰写者撰写的摘要。
本文主要探讨学术论文英文摘要。本文所选英文摘要例子均引自国内外语类核心期刊，以体现该研究对象的代表性。Arbor认为，根据撰写方法的不同，学术论文摘要主要有两种：一种是结果式摘要。这种摘要围绕研究发现结果为中心而撰写，有时会附带写上基于发现结果而得出的结论;另外一种是总结陈述式摘要，即对所撰写论文的总结陈述。
还需要注意的是，这片摘要并没有在研究结果的基础上写出据此得出的结论。选择何种方法撰写摘要，主要根据论文内容所属的研究类型和所采取的研究方法而定。本文认为，一般情况下，采用定量研究方法的论文摘要多为“结果式”;采用定性研究方法的论文摘要多为“总结陈述式”。
二、英文摘要的结构要素
黄国文将英文摘要的结构要素归纳为六个：主题阐述、背景信息、目的.陈述、方法论和语料、研究结果、发现和研究所带来的启示和结论，并指出并非所有的论文摘要都完全包括这六个要素，“事实上，一些成分是必选的，而其他成分是可有可无的”。
Slade也认为,“一篇摘要必须包括简明扼要的主题阐述，主要发现及意义，还有结论”。“摘要中一定要有方法和论文内容的重要词句，这样，此篇摘要才会在电脑中被搜索到，进而让读者决定是否阅读”。所以，在撰写摘要时，要根据具体的论文明确判断哪些要素是摘要必须包括的。
三、英文摘要的语法特点
1.英文摘要语句中主语的语法特点
黄国文认为，英文摘要中主要是由名词短语或作名词词组作主语。但本文所引实例可以使我们更具体的发现，充当主语的通常为非人的名词短语或名词词组。被动语态也在适当的时候出现，这些特点都表明摘要写作要遵循客观性这一道理。表明论文的研究不是作者的主观想象，而是通过大量的科学研究而的得出的结论。
2.英文摘要的时态特点
时态上，摘要也具有其自身的特点。Arbor认为，表示总结的语句通常与一般现在时或现在完成时;表示结果的语句可用过去时。Arbor还指出，“现在时态用于表示结果的语句这一情况通常易发生在自然科学领域而少发生在社会科学领域”。“主观用语的使用也易发生在自然科学领域”。
四、英文论文摘要的书写方法
摘要是论文内容的简要陈述，是一篇完整的、可以独立使用的短文，因而必须具有自含性。即：读者即使不阅读论文的全文也可以从摘要中获得必要的、与论文等量的信息，以判断有无必要阅读全文。摘要一般应包括研究题目的选择理由和目的;研究的方法或者过程;研究的发现或者成果。
五、摘要格式
英文主标题格式：可选用本模板中的样式所定义的“论文英文主标题”，或手动设置(Times New Roman
英文副标题格式：可选用本模板中的样式所定义的“论文英文副标题”，或手动设置(Times New Roman，小四，加粗，居中，段前0.5行，段后0行，单倍行距)。
英文标题下空一行为英文摘要。英文摘要正文格式：可选用本模板中的样式所定义的“英文摘要正文”或手动设置(Times New Roman，小四，行距为固定值20磅)。英文摘要后空一行，另起一行列出英文关键词。“Key words：”格式：首行缩进2字符，Times New Roman，小四，加粗。“Key words：”后紧接英文关键词。关键词之间用分号间隔，最后一个末尾不加标点。英文关键词全部小写。英文关键词格式：Times New Roman，小四，行距为固定值20磅。
