1. Media Language and Semiotics | 媒体语言与符号学
Media language refers to the system of codes and conventions that producers use to communicate meaning. Semiotics, pioneered by Ferdinand de Saussure and Charles Peirce, treats media texts as collections of signs. A sign is made up of the signifier (the physical form, such as a word or image) and the signified (the mental concept it represents). For example, a red rose can be a signifier for the signified of romance or passion.
媒体语言指制作者用来传递意义的代码与惯例系统。由索绪尔和皮尔斯开创的符号学将媒体文本视为符号的集合。一个符号由能指（物理形式，比如词语或图像）和所指（它所代表的心理概念）构成。例如，一朵红玫瑰可以是能指，其所指是浪漫或激情。
Denotation is the literal, descriptive meaning of a sign, while connotation is the associated, cultural meaning. A photograph of a stormy sea denotes a body of water under dark clouds, but may connote danger, turmoil or emotional conflict. Analysing both layers is crucial for deconstructing media texts.
外延是符号的字面、描述性意义，而内涵是与之相关联的文化意义。一张狂风暴雨的大海照片，其外延是黑云下的水域，但可能内涵着危险、动荡或情感冲突。解析媒体文本时，同时分析这两个层面至关重要。
Technical codes involve camera work (close-ups, high angles), lighting (low-key for mystery), editing (fast cuts for excitement), and sound (diegetic vs non-diegetic). Written and symbolic codes include headlines, captions, body language and mise-en-scène. Mastery of these elements allows you to explain how meaning is constructed.
技术代码包括镜头运用（特写、仰拍）、灯光（低调光营造神秘感）、剪辑（快切传达兴奋）和声音（剧情声与非剧情声）。书面与象征代码包括标题、图说、肢体语言和场面调度。掌握这些元素，你就能解释意义是如何被建构的。
2. Narrative and Structure | 叙事与结构
Narrative is the way a story is organised and presented. Todorov's narrative theory proposes a five-stage structure: equilibrium (a state of balance), disruption (something disturbs it), recognition (the disruption is noticed), attempt to repair, and a new equilibrium. This model can be applied to many film and television narratives, from fairy tales to superhero movies.
叙事是故事被组织和呈现的方式。托多罗夫的叙事理论提出了五阶段结构：平衡（稳定状态）、打破平衡（某事扰乱）、意识到破坏、尝试修复和新的平衡。该模型适用于众多电影电视叙事，从童话故事到超级英雄电影。
Vladimir Propp identified seven character types (spheres of action) in folk tales: the hero, villain, donor, helper, princess, dispatcher and false hero. While most modern media texts feature more complex characters, these archetypes often underpin character functions in advertising, drama serials and video games.
普罗普识别出民间故事中的七种角色类型（行动圈）：英雄、反派、赠与者、帮手、公主、派遣者和伪英雄。尽管大多数现代媒体文本的角色更加复杂，但这些原型常构成广告、连续剧和电子游戏中角色功能的基础。
Barthes' enigma and action codes explain how narratives create suspense and drive the plot. An enigma code poses a question that keeps the audience guessing (e.g., a mysterious locked door), while action codes suggest that a particular action will lead to a consequence (a character picking up a knife implies violence).
巴特的谜题代码与行动代码解释了叙事如何制造悬念并推动情节。谜题代码提出一个问题，让观众不断猜测（如一扇神秘的上锁的门），而行动代码则暗示某个动作将导致后果（角色拿起刀意味着暴力）。
3. Genre and Conventions | 类型与惯例
Genre is a way of categorising media texts based on shared conventions. Conventions are the expected features that define a genre, such as the dark alleyways and jazz music in film noir, or the upbeat presenter and headline issues in a tabloid talk show. Audiences use genre to predict and select media; producers use it to target markets and innovate.
类型是基于共享惯例对媒体文本进行分类的方式。惯例是定义一个类型的预期特征，例如黑色电影中的黑暗小巷和爵士乐，或格调小报脱口秀中活泼的主持人与头版话题。受众利用类型进行预测和选择；制作者则借此定位市场并进行创新。
Genres are not fixed; they evolve through repetition and variation. Steve Neale argued that genre consists of 'repetition and difference'. A successful horror film respects conventions like the jump scare and isolated setting, but also offers something new to avoid being predictable. Hybrid genres, such as romantic comedy or docudrama, blend conventions from two or more genres.
类型并非一成不变；它们通过重复与变异而演变。史蒂夫·尼尔认为类型由“重复与差异”构成。一部成功的恐怖片尊重突吓和孤绝场景等惯例，但也会提供新意，避免可预测性。混合类型，如浪漫喜剧或纪录剧情片，融合了两种或多种类型的惯例。
The iconography, setting, characters and narrative patterns of a genre form a repertoire of elements. For instance, a Western typically features Stetson hats, saloons, sheriffs and a conflict between civilisation and wilderness. Being able to identify and discuss these elements is a key exam skill.
