📚 Year 7 AQA Media Studies: Formula & Theorem Quick Reference Handbook | 7年级AQA媒体研究：公式定理速查手册
In Media Studies, just like in Mathematics or Science, we use special ‘formulas’ and ‘theorems’ to understand how media texts are constructed and how they affect audiences. These are not equations with numbers, but powerful ideas and frameworks developed by media experts. This handbook compiles the essential formulas every Year 7 AQA Media Studies student needs to analyse films, advertisements, magazines, and online content with confidence.
在媒体研究中，就像在数学或科学中一样，我们使用特殊的“公式”和“定理”来理解媒体文本是如何构建的，以及它们如何影响受众。这些并非带数字的方程式，而是由媒体专家开发的强大思想和框架。本手册汇编了每位 7 年级 AQA 媒体研究学生需要的基本公式，以便自信地分析电影、广告、杂志和在线内容。
1. The Sign Formula: Signifier + Signified = Sign | 符号公式：能指 + 所指 = 符号
Signifier (the physical form) + Signified (the mental concept) = Sign (the meaning)
This formula, inspired by Ferdinand de Saussure, is the foundation of media language. The signifier is what we see or hear (a word, image, sound). The signified is the idea or concept it triggers in our mind. Together they form a sign with a shared meaning in a culture. For example, a red rose (signifier) may signify love or romance (signified). Media producers carefully choose signifiers to construct specific meanings.
这个公式起源于费迪南德·德·索绪尔，是媒体语言的基础。能指是我们看到或听到的（词语、图像、声音）。所指是它在我们头脑中引发的想法或概念。它们共同构成一个在某种文化中具有共享意义的符号。例如，一朵红玫瑰（能指）可能意指爱情或浪漫（所指）。媒体制作人精心选择能指来构建特定的意义。
2. Camera Shot & Angle Equations | 镜头与角度方程式
Camera shots and angles are like visual equations. Each type of shot or angle is a variable that influences the audience’s understanding of character, setting, and emotion. Knowing these ‘equations’ lets you ‘solve’ media texts.
摄影机镜头和角度就像视觉方程式。每种镜头或角度都是一个变量，影响着观众对角色、场景和情绪的理解。了解这些“方程式”让你能够“解构”媒体文本。
Extreme Long Shot (ELS) = Setting + Context (Character is small, environment dominates)
极远景 = 场景 + 背景（角色很小，环境主导）。通常用于建立场景或展示规模。
Long Shot (LS) = Full Body + Surroundings
远景 = 全身 + 周围环境。展示角色在环境中的位置。
Mid Shot (MS) = Waist Up + Facial Expression + Gesture
中景 = 腰部以上 + 面部表情 + 手势。常用于对话场景，建立角色关系。
Close-Up (CU) = Head/Face + Emotion + Detail
特写 = 头部/面部 + 情感 + 细节。让观众强烈感受角色的情绪。
Extreme Close-Up (ECU) = One Feature (eye, mouth) + Intensity
极特写 = 一个特征（眼睛、嘴巴） + 强度。创造紧张或强调细节。
High Angle = Looking Down → Character Appears Weak/Small
俯角 = 向下看 → 角色显得弱小/脆弱。
Low Angle = Looking Up → Character Appears Powerful/Dominant
仰角 = 向上看 → 角色显得强大/支配。
Eye-Level Angle = Equality → Neutral, Realistic
平视角度 = 平等 → 中性、现实感。
3. The Mise-en-Scène Equation | 场面调度公式
Mise-en-scène translates to ‘everything in the frame’. The formula combines all visual elements to create meaning:
场面调度翻译为“画面中的一切”。该公式将所有视觉元素结合起来创造意义：
Mise-en-Scène = Setting + Lighting + Costume + Props + Colour + Body Language
Setting: The location and time period provide context. A dystopian wasteland instantly signals danger and struggle.
场景：地点和时间段提供背景。一片反乌托邦的荒原立即传达出危险和挣扎。
Lighting: High-key lighting (bright, even) suggests happiness or glamour; low-key lighting (shadows, contrast) creates mystery or fear.
灯光：高调灯光（明亮、均匀）暗示快乐或魅力；低调灯光（阴影、对比）制造神秘或恐惧。
Costume: Clothes and make-up indicate character’s personality, status, or role. A superhero’s cape signifies power.
服装：衣服和妆容表明角色的个性、地位或角色。超级英雄的斗篷象征着力量。
Colour: Colours carry meaning – red for danger/passion, blue for calm/cold, green for nature/envy.
色彩：颜色携带意义——红色代表危险/激情，蓝色代表平静/寒冷，绿色代表自然/嫉妒。
Body Language: Posture and facial expressions communicate emotions non-verbally.
身体语言：姿态和面部表情非语言地传达情感。
4. The Sound Formula: Diegetic + Non-Diegetic Sound = Atmosphere | 声音公式：剧情声 + 非剧情声 = 氛围
Sound in media is classified into two main types. The formula for soundscape analysis is:
媒体中的声音分为两种主要类型。声景分析的公式是：
Total Sound Atmosphere = Diegetic Sound (in the story world) + Non-Diegetic Sound (outside the story world)
Diegetic sound includes dialogue, footsteps, traffic noise, music from a radio within the scene – anything characters can hear. Non-diegetic sound includes voice-overs, background music (score), and sound effects added for the audience only. The combination shapes mood: a horror film uses diegetic creaking doors with non-diegetic tense music to maximise fear.
剧情声包括对话、脚步声、交通噪音、场景内的收音机音乐——任何角色能听到的。非剧情声包括画外音、背景音乐（配乐）和仅为观众添加的音效。两者的组合塑造情绪：一部恐怖片使用剧情声的吱吱作响的门和非剧情声的紧张音乐，以最大化恐惧。
5. Todorov’s Narrative Theorem: Equilibrium → Disruption → New Equilibrium | 托多罗夫叙事定理：平衡 → 打破 → 新平衡
Narrative Structure = Equilibrium → Disruption/Conflict → Resolution/New Equilibrium
Tzvetan Todorov suggested that most stories follow a three-part structure. First, a state of balance (equilibrium) is established. Then an event or villain disrupts this balance, creating conflict. Finally, the disruption is resolved, leading to a new, often improved, equilibrium. This formula is visible in fairy tales, action films, and even advertisements.
茨维坦·托多罗夫提出，大多数故事都遵循三部分结构。首先，建立一种平衡状态（均衡）。然后一个事件或反派打破了这种平衡，制造冲突。最后，冲突得到解决，形成一个新的、通常是更好的平衡。这个公式在童话故事、动作片甚至广告中都很常见。
Example: In a typical superhero film, the city is peaceful (equilibrium), a villain attacks (disruption), the hero defeats the villain (resolution), and the city is safe again but with a changed hero (new equilibrium).
示例：在一部典型的超级英雄电影中，城市是和平的（均衡），反派发动攻击（打破），英雄击败反派（解决），城市再次安全，但英雄有所改变（新均衡）。
6. Propp’s Character Formulae: 7 Character Types | 普罗普角色公式：七种角色类型
Vladimir Propp analysed Russian folk tales and identified seven recurring character types. These ‘character formulas’ help us understand narrative roles:
弗拉基米尔·普罗普分析了俄罗斯民间故事，并识别出七种反复出现的角色类型。这些“角色公式”帮助我们理解叙事角色：
The Hero: The main character who seeks something or someone, often on a quest. Example: Harry Potter.
英雄：寻求某物或某人的主要角色，通常踏上征程。示例：哈利·波特。
The Villain: Opposes the hero and creates the disruption. Example: Voldemort.
反派：与英雄对立，制造混乱。示例：伏地魔。
The Donor: Gives the hero a magical object or special knowledge. Example: Dumbledore giving Harry the invisibility cloak.
捐赠者：给英雄提供魔法物品或特殊知识。示例：邓布利多给哈利隐形衣。
The Helper: Accompanies and aids the hero. Example: Ron and Hermione.
助手：陪伴并帮助英雄。示例：罗恩和赫敏。
The Princess (or Prize): The reward for the hero’s success; often needs rescuing. Example: Princess Leia.
公主（或奖品）：英雄成功的奖励；通常需要救援。示例：莱娅公主。
The Dispatcher: Sends the hero on the mission. Example: Gandalf sending Bilbo.
派遣者：派遣英雄执行任务。示例：甘道夫派遣比尔博。
The False Hero: Appears good but is eventually revealed as bad. Example: Professor Quirrell in Harry Potter.
假英雄：表面善良，但最终被揭露是坏人。示例：《哈利·波特》中的奇洛教授。
7. The Audience Uses and Gratifications Formula: 4 Reasons We Use Media | 受众使用与满足公式：我们使用媒体的四个理由
The Uses and Gratifications theory by Blumler and Katz states that audiences actively choose media to satisfy specific needs. The formula is:
布鲁姆勒和卡茨的使用与满足理论指出，受众主动选择媒体来满足特定需求。公式是：
