📚 Year 8 CIE Media: Formula & Theorem Quick Reference Handbook | Year 8 CIE 媒体：公式定理速查手册
This handbook gathers the essential 'formulas' and 'theorems' of media studies – the key concepts, models, and rules that help you decode any media text. Treat each idea as a tool for analysis, just like a maths formula is used to solve problems. From semiotics to narrative theory, camera conventions to audience frameworks, this reference will support your revision and classroom discussions throughout the Year 8 CIE Media course.
这本手册汇集了媒体研究中的核心“公式”与“定理”——帮助你解读任何媒介文本的关键概念、模型和规则。把每个概念都看作一种分析工具，就像数学公式用于解题一样。从符号学到叙事理论，从镜头惯例到受众框架，这份速查手册将为你整个 Year 8 CIE 媒体课程的复习和课堂讨论提供有力支持。
1. Semiotics: Signifier and Signified | 符号学：能指与所指
Every sign in media is made of two parts: the signifier (the physical form – a word, image, sound) and the signified (the mental concept it triggers). The relationship is learned through culture. A red heart shape (signifier) conveys love (signified) because we have been taught this connection.
媒介中的每一个符号都由两部分组成：能指（物理形式——词语、图像、声音）和所指（它所引发的心理概念）。这种关系是通过文化习得的。红心形状（能指）传达爱意（所指），因为我们被教会了这种关联。
Mini-formula: Sign = Signifier + Signified
迷你公式：符号 = 能指 + 所指
2. Peirce's Sign Categories | 皮尔斯的符号分类
Charles Peirce divided signs into three types based on how the signifier relates to the signified. This 'theorem' helps you classify any media element.
查尔斯·皮尔斯根据能指与所指的关联方式将符号分为三类。这个“定理”能帮助你给任何媒介元素归类。
| Icon | Index | Symbol |
|---|---|---|
| Resembles the object (e.g. a photograph of a tree looks like a tree) | Has a direct physical link (e.g. smoke is an index of fire) | Arbitrary, learned by convention (e.g. a red rose means romance) |
| 像似符 | 指示符 | 象征符 |
|---|---|---|
| 与对象相似（例如一张树的照片看起来像一棵树） | 与对象有直接物理联系（例如烟是火的指示） | 任意约定俗成（例如红玫瑰代表爱情） |
3. Todorov's Narrative Structure | 托多罗夫叙事结构
Tzvetan Todorov proposed that most stories follow a five‑step 'formula' moving from one state of equilibrium to another. This model is especially visible in films, TV dramas, and advertisements with mini‑stories.
茨维坦·托多罗夫提出，大多数故事都遵循一个五步“公式”，从一种平衡状态过渡到另一种平衡。这个模型在电影、电视剧以及带有微型故事的广告中尤其常见。
The 5‑step model:
五步模型：
1. Equilibrium (一切正常) → 2. Disruption (平衡被打破) → 3. Recognition (意识到破坏) → 4. Attempt to repair (尝试修复) → 5. New equilibrium (新的平衡)
4. Propp's Character Types | 普罗普角色类型
Vladimir Propp analysed Russian fairy tales and found that characters fit into seven recurring 'functions'. Unlike Todorov's plot focus, Propp gives us a cast‑of‑characters formula for storytelling.
弗拉基米尔·普罗普分析了俄罗斯民间故事，发现角色可以归入七种重复出现的“功能”。与托多罗夫关注情节不同，普罗普为我们提供了一套故事叙述的角色阵容公式。
- The Villain (反派) – opposes the hero
- The Donor (捐助者) – gives a magical object or advice
- The Helper (帮手) – assists the hero
- The Princess (公主) – sought‑after figure, often reward
- The Dispatcher (派遣者) – sends the hero on the quest
- The Hero (英雄) – main protagonist
- The False Hero (假英雄) – pretends to be good but is exposed
- 反派 – 与英雄对立
- 捐助者 – 提供魔法物品或建议
- 帮手 – 协助英雄
- 公主 – 被寻求的人物，常是奖励
- 派遣者 – 派英雄踏上征程
- 英雄 – 主要主人公
- 假英雄 – 假装好人但最终暴露
5. Camera Shots and Angles | 摄影机镜头与角度
A media 'formula' can be a simple rule: the shot size and angle directly influence how the audience feels about a character or setting. The table below summarises the basic visual grammar.
媒介“公式”可以是一条简单的规则：镜头大小和角度会直接影响观众对角色或场景的感受。下表总结了基本的视觉语法。
| Shot/Term | Effect (English) | 效果 (中文) |
|---|---|---|
| Extreme Long Shot (ELS) | Establishes setting; character is small, often isolated | 交代环境；角色渺小，常显孤立 |
| Close‑up (CU) | Shows emotion; creates intimacy or tension | 表现情感；营造亲密感或紧张感 |
| Low Angle | Makes subject look powerful, dominant | 使被摄体看起来强大、占主导 |
| High Angle | Makes subject look weak, vulnerable | 使被摄体显得弱小、易受伤害 |
6. Editing Techniques | 编辑技巧
Editing is the 'grammar' of moving image. The way shots are joined creates meaning. Two key 'formulae' are continuity editing (invisible cuts that flow smoothly) and the Kuleshov effect (meaning created by the order of images).
剪辑是动态影像的“语法”。镜头的连接方式会产生意义。两个关键的“公式”是连贯性剪辑（无缝连接、流畅叙事）和库里肖夫效应（通过画面顺序创造意义）。
- Continuity editing: shot/reverse shot, eyeline match, 180° rule – these keep the viewer oriented.
- Montage: rapid succession of short shots to compress time or create emotional impact.
- Jump cut: a jarring cut that breaks continuity, often used for stylistic effect.
- 连贯性剪辑：正反打、视线匹配、180°规则——保持观众的空间方向感。
- 蒙太奇：快速连续短镜头以压缩时间或营造情感冲击。
- 跳切：打破流畅感的突兀剪辑，常用于风格化表达。
7. Sound in Media | 媒体中的声音
Sound can be diegetic (coming from within the story world) or non‑diegetic (added for the audience, e.g., background music). This simple binary is a fundamental analytical 'theorem' for any audio‑visual text.
声音可以是剧情内音（来自故事世界内部）或非剧情内音（为观众添加，如背景音乐）。这个简单的二元分类是分析任何视听文本的基本“定理”。
- Diegetic: dialogue, footsteps, car engines, radio playing in the scene.
- Non‑diegetic: voice‑over narration, musical score, sound effects added in post‑production.
- 剧情内音：对话、脚步声、汽车引擎、场景内收音机播放的声音。
- 非剧情内音：画外音叙事、配乐、后期添加的音效。
Remember the formula: Sound = Diegetic + Non‑diegetic. Always ask: who can hear this sound?
记住公式：声音 = 剧情内音 + 非剧情内音。始终问：谁能听到这个声音？
8. Mise-en-scène: Visual Composition | 场景调度：视觉构图
Mise‑en‑scè everything placed in front of the camera: set design, props, costume, lighting, and actors' positioning. The 'rule of thirds' ; placing key elements along the lines or intersections creates a balanced, dynamic image.
场景调度是摄影机前的一切：布景设计、道具、服装、灯光以及演员的位置。“三分法”是一种构图公式，将画面划分为3×3的网格；将关键元素放在线条或交点上可以形成平衡、有活力的图像。
Additional 'quick‑check formulas':
- Foreground, middle ground, background – layers create depth.
- Lead room – space in front of a moving subject to suggest direction.
- Headroom – space above a character's head; too much or too little changes meaning.
额外的“速查公式”：
- 前景、中景、背景 – 层次营造深度感。
- 引导空间 – 运动主体前方的空间，暗示方向。
- 头顶空间 – 角色头顶上方的空间；过多或过少都会改变含义。
9. Lighting and Colour | 灯光与色彩
Lighting creates mood and directs attention. The basic formula is three‑point lighting: key light (main source), fill light (softens shadows), and back light (separates subject from background). Low‑key lighting (high contrast, deep shadows) often signals mystery or danger; high‑key lighting (bright, even) suggests optimism or realism.
灯光营造情绪并引导注意力。基本公式是三点布光：主光（主要光源）、辅助光（柔化阴影）和背光（将主体与背景分离）。低色调照明（高对比、深阴影）常暗示神秘或危险；高色调照明（明亮均匀）则传达乐观或真实感。
Colour also follows a 'connotation formula':
- Red – danger, passion, anger
- Blue – calm, sadness, technology
- Yellow – happiness, warmth, caution
色彩同样遵循“内涵公式”：
- 红色 – 危险、激情、愤怒
- 蓝色 – 平静、悲伤、科技
- 黄色 – 快乐、温暖、警示
10. Audience Theories | 受众理论
Two contrasting 'theorems' help explain how audiences receive media. The hypodermic needle model (passive audience) assumes media injects ideas directly into a passive audience, while uses and gratifications theory (active audience) says people actively choose media to satisfy needs: information, personal identity, social interaction, and entertainment.
两种对立的“定理”有助于解释受众如何接收媒介信息。皮下注射模型（被动受众）假设媒体将观念直接注入被动的受众；而使用与满足理论（主动受众）则认为人们主动选择媒体来满足需求：信息获取、个人身份认同、社会互动和娱乐。
Active audience formula: Media choice = function of needs (information + identity + social + entertainment).
主动受众公式：媒体选择 = 需求函数（信息 + 身份 + 社交 + 娱乐）。
11. Representation and Stereotypes | 再现与刻板印象
All media texts are representations of reality, not reality itself. A key 'theorem' is that repeated representations can create stereotypes – simplified, often exaggerated, images of a group. The stereotype 'formula' works by selecting a few traits and exaggerating them, reducing complexity to a shorthand.
所有媒体文本都是对现实的再现，而非现实本身。一个关键的“定理”是，反复出现的再现会形成刻板印象——对某个群体简化且常常夸大的形象。刻板印象的“公式”通过选取少数特征并加以夸大，将复杂性简化为一种速记符号。
- Always ask: Who is represented? By whom? For what purpose?
- Countertypes challenge stereotypes by presenting more complex, positive portrayals.
- 始终问：谁被再现了？由谁再现？出于什么目的？
- 反刻板印象通过呈现更复杂、正面的描绘来挑战刻板印象。
12. Media Industry: Public vs Commercial | 媒体产业：公共与商业广播
A structural 'formula' divides broadcasters into two models: public service broadcasting (PSB), funded by licence fees or government, aiming to inform, educate, entertain – think BBC; and commercial broadcasting, funded by advertising, where content is designed to attract audiences for advertisers – think ITV or YouTube ads.
一种结构性“公式”将广播机构分为两种模式：公共服务广播（PSB），由执照费或政府资助，旨在告知、教育、娱乐——如BBC；商业广播，由广告资金支持，内容旨在吸引受众以服务于广告商——如ITV或YouTube广告。
Understanding this industry 'theorem' helps explain why certain programmes exist: PSB may take risks on niche content; commercial channels tend to programme proven popular formats.
理解这一产业“定理”有助于解释为何存在某些节目：公共服务广播可能在利基内容上冒险；商业频道则倾向于播放已被验证受欢迎的节目形式。
