【摘要】 越来越多的癌症患者在网络上分享抗癌经历，这些自述不仅为记录者提供了医学讨论平台，也为其他癌症患者提供了大量医疗信息和精神慰藉。本研究从知乎网络平台收集癌症患者自述，并以其为语料自建语料库，通过语料库关键词及其索引行研究方法，结合批评话语分析中的话语策略理论，从语料库批评话语分析角度深入探究癌症患者的身份建构。研究发现，癌症患者通过自述话语主要构建了七种身份，即战斗者身份、受难者身份、回馈者身份、恐慌者身份、拖累者身份、求助者身份和重生者身份。该研究旨在为癌症患者提供借鉴与参考，帮助他们以乐观的心态看待疾病，建立积极的自我身份认知。更多还原

【Abstract】 More and more cancer patients are sharing their anti-cancer experiences online. These self-narratives not only serve as a platform for medical discussions but also offer a wealth of medical information and spiritual solace for other cancer patients. This study collected self-statements from cancer patients on the Zhihu online platform, and constructed a corpus. Through the study of keywords and their index lines under the guidance of discursive strategies of critical discourse analysis, it delved deeply into the identity construction of cancer patients from the perspective of corpus-assisted critical discourse analysis. It is shown that cancer patients construct seven main identities through self-narrative discourse, including fighters, victims, givers, panickers, procrastinators, seekers and rebirths. The primary aim of this study is to provide a reference for cancer patients, assisting them in adopting an optimistic attitude towards the disease and establishing a positive self-identity cognition.更多还原
