社交媒体是一种行为方式，是人类参与社交和分享经验这一固有需求的表现。社会环境与媒体环境互相渗透，在创造与分享的过程中，新语言伴随着新技术一起诞生。社交媒体影响人们的线上线下社交行为，进而影响着信息传播和语言文化等社会要素。

本报告从翻译理论家卡特福德的翻译转换理论出发，以笔者选择的翻译实践项目《混乱的机器：社交媒体如何重塑我们的思维和世界》（The Chaos Machine: The Inside Story of How Social Media Rewired Our Minds and Our World）第一章节选为例，主要分析从原文到译文的语言结构转换如何实现，探讨社交媒体和互联网文化背景的文本翻译策略。这份翻译实践报告包含四个部分：项目概述、翻译过程、翻译理论和相关案例分析。第一章将深入探讨翻译实践报告的背景，以及研究的目标和重要性，以便更好地理解这一领域。第二章则介绍翻译的各个阶段，包括准备工作、实施过程和译后部分。第三章将引入翻译转换理论并深入探讨，并通过实际案例来证明其重要性。主要结合第二章文本特征分析，从翻译实践难点出发，从文化负载词、修辞以及长难句翻译这三大部分详述翻译转换理论的应用。这三大翻译难点均运用到了到层次与范畴转换，具体包括不同词类的词性转换与语法时态的转换，主语及主题突出、主动与被动语态的转换；除此之外，在文化负载词的翻译分析中还一定程度上探讨了文化转换策略。第四章则是翻译实践总结，总结翻译过程中不足之处、改进方法及反思展望。

通过本翻译实践研究分析后，笔者总结发现，对于文化负载词的翻译，主要从单复数、词性以及从句与短语的转换入手，同时结合社交媒体及网络背景和译入语文化，选择与原文等值的恰当语域进行翻译，实现文化转换。对于修辞手法的翻译，主要通过将短语转译为句子、调整主语和主题突出、主被动语态的转换，实现单位转换和结构转换等。而对于长难句的翻译，则对原文的语言结构进行适当调整与重组，比如时态、肯定与否定的转换等，以适应目的语的语言结构，形成可读性强，便于读者理解的译文。

Social media is a platform where human engage in socializing and sharing experiences. The society and media environments interpenetrate each other, and in the process of creating and sharing, new languages are born along with new technologies. Social media affects people's social behavior both online and offline, which in turn affects social elements such as information dissemination and language culture.

Starting from Catford's translation shifts theory, this report takes the translation practice project The Chaos Machine: The Inside Story of How Social Media Rewired Our Minds and Our World chapter one. The report focuses on analyzing how the shifts of language structure from the original text to the translated text is realized and exploring the translation strategies of text under social media and Internet background. This translation practice report is divided into four parts, including introduction, translation process, translation shifts theory and relevant case study, and summary. The first part introduces the background of the translation practice report, and elaborates the purpose and significance of the study. The second chapter includes pre-translation preparation, translation process and post-translation review. Chapter three contains an overview of translation shifts theory and relevant case studies. The application of translation shifts theory is discussed in the context of the previous analysis of text characteristics, from the three major difficulties: culture-loaded words, rhetorical techniques and translation of long and difficult sentences. These are all applied to hierarchical and category shifts, specifically including the shifts of lexical and grammatical tenses of different parts of speech, the shifts of subject and theme prominence, active and passive voice; in addition, the translation analysis of culture-loaded words also discusses cultural shifts to a certain extent. The fourth chapter is a summary of translation practice, summarizing the shortcomings, improvement methods and reflective outlook in the translation process.

After analyzing, the author concludes that for culture-loaded words, the translation could mainly applies shifts of singular and plural forms, clauses and phrases, and also combines the social media and network background to select the equivalence domain of to realize cultural shift. For the translation of rhetorical techniques, unit shifts and structure shifts are realized mainly by translating phrases into sentences, adjusting the subject and theme prominence, and converting the subject-passive voice. As for the translation of long and difficult sentences, the language structure of the original text is appropriately adjusted and reorganized, such as the shifts of tenses, affirmation and negation, in order to adapt to the language structure of the translated language and form a readable translation.
