📚 Year 7 AQA Media Studies: Formulas & Theories Quick Reference | Year 7 AQA 媒体：公式定理速查手册
Just as mathematics relies on formulas to solve problems, Media Studies uses a set of key concepts and theories that act like ‘formulas’ to decode and understand media texts. This quick reference handbook breaks down essential principles you’ll encounter in Year 7, from semiotics to audience models.
就像数学依靠公式来解题一样，媒体研究使用一系列关键概念和理论，如同“公式”一般，帮助我们解读并理解各种媒介文本。这本速查手册将拆解你在 7 年级会学到的核心原理，从符号学到受众模型。
1. Semiotics: The Sign Equation | 符号学：符号方程式
In semiotics, a sign is the basic unit of meaning. The sign equation is: Sign = Signifier + Signified. The signifier is the physical form (image, word, sound), and the signified is the mental concept it triggers.
在符号学中，符号是意义的基本单位。符号方程式是：符号 = 能指 + 所指。能指是物理形式（图像、词语、声音），所指是它引起的心理概念。
For example, a red rose (the signifier) often signifies romance or love (the signified). In media texts, producers carefully choose signs to convey specific messages.
例如，一朵红玫瑰（能指）通常代表浪漫或爱情（所指）。在媒介文本中，制作者精心挑选符号来传达特定的信息。
2. Camera Shots & Angles: The Visual Grammar | 镜头与角度：视觉语法
Camera shots and angles form a visual grammar that guides how we feel about a character or scene. A close-up shot frames a subject’s face to reveal intense emotion, creating a sense of intimacy or tension.
镜头与角度构成了一种视觉语法，引导我们对角色或场景的感受。特写镜头框住主体的面部以揭示强烈的情感，营造亲密或紧张感。
An extreme wide shot establishes the setting and makes characters appear small or vulnerable. A low-angle shot looks up at a subject, making them appear powerful, while a high-angle shot looks down, making them seem weak.
极远景镜头建立场景，使角色显得渺小或脆弱。低角度镜头仰拍主体，使其显得强大；高角度镜头俯拍，使其显得弱小。
Low Angle = Power | High Angle = Vulnerability
3. Colour Symbolism: The Colour Code | 色彩象征：色彩密码
Colours in media are not just decorative; they follow a ‘colour code’ that communicates mood and meaning. Red often signals danger, passion, or anger, while blue suggests calmness, trust, or sadness.
媒体中的色彩并不仅仅是装饰，而是遵循一套“色彩密码”，传达情绪和含义。红色常表示危险、激情或愤怒；蓝色则暗示平静、信任或悲伤。
Warm colours (red, orange, yellow) can create a sense of warmth and energy, often used in food advertising. Cool colours (blue, green) are linked to nature, health, and tranquility. Black can represent evil, mystery, or elegance.
暖色（红、橙、黄）能营造温暖和活力感，常用于食品广告。冷色（蓝、绿）与自然、健康和宁静相关。黑色可以表示邪恶、神秘或优雅。
4. Mise-en-scène: The Setting Formula | 场面调度：场景公式
Mise-en-scène refers to everything placed in front of the camera: setting, props, costume, and lighting. The formula is: Setting + Props + Costume + Lighting = Meaning. Each element contributes to the story and character development.
场面调度指摄影机前的一切：场景、道具、服装和灯光。其公式为：场景 + 道具 + 服装 + 灯光 = 意义。每个元素都有助于故事和角色的发展。
A messy bedroom with scattered clothes suggests a disorganised character; a lab coat and glasses can signify intelligence or scientific authority. Lighting can be high-key (bright, low contrast) for comedies or low-key (dark shadows) for thrillers.
杂乱的卧室和散落的衣物暗示一个缺乏条理的角色；白大褂和眼镜则可表示智慧或科学权威。灯光可以是高调光（明亮、低对比）用于喜剧，或低调光（暗影）用于惊悚片。
5. Representation & Stereotypes: The Bias Theorem | 再现与刻板印象：偏差定理
Media representations are constructed versions of reality. The ‘bias theorem’ reminds us that producers make choices about how to portray people, events, and issues. A stereotype is a simplified and often exaggerated representation of a group, reducing them to a few characteristics.
媒体再现是现实的构建版本。“偏差定理”提醒我们，制作人对于如何描绘人物、事件和议题做出选择。刻板印象是对群体的简化且往往夸张的再现，将其简化为少数特征。
For instance, teenagers are sometimes stereotyped as moody or rebellious in TV dramas. Such portrayals can shape audience perceptions and reinforce unfair biases. Critical analysis involves questioning why a representation was constructed in that way.
例如，在电视剧中，青少年有时被刻板化为情绪化或叛逆。这种描绘可能塑造观众的看法并强化不公的偏见。批判性分析包括追问为什么再现要以这种方式构建。
6. Audience Theory: Uses & Gratifications Model | 受众理论：使用与满足模型
Instead of asking what media do to people, the Uses & Gratifications model asks what people do with media. Audiences actively choose media to satisfy four main needs: Information, Personal Identity, Integration & Social Interaction, and Entertainment.
“使用与满足”模型不问媒体对人们做了什么，而是问人们用媒体做什么。受众主动选择媒体来满足四种主要需求：信息、个人身份认同、整合与社交互动，以及娱乐。
Watching a news programme fulfils the need for information; following a celebrity on Instagram might support personal identity; discussing a film with friends provides social interaction; playing a video game offers entertainment and escape.
观看新闻节目满足信息需求；在 Instagram 上关注名人可能支持个人身份认同；与朋友讨论一部电影提供了社交互动；玩电子游戏则提供娱乐和逃避现实。
7. Narrative Theory: Todorov’s Equilibrium Principle | 叙事理论：托多罗夫平衡原则
Todorov’s narrative theory suggests that most stories follow a five-stage pattern: Equilibrium (a stable beginning), Disruption (something disturbs the balance), Recognition (characters realise the problem), Attempt to Repair, and New Equilibrium (a restored, often changed, balance). This is a fundamental storytelling formula.
托多罗夫的叙事理论认为，大多数故事遵循五阶段模式：平衡（稳定开端）、破坏（某事打破平衡）、认识（角色意识到问题）、尝试修复，以及新平衡（恢复但常有改变的平衡）。这是一个基本的叙事公式。
In many superhero films, the city is safe (equilibrium), a villain attacks (disruption), the hero acknowledges the threat (recognition), battles the villain (repair), and the city is saved but the hero has changed (new equilibrium).
在许多超级英雄电影中，城市安全（平衡），反派发动攻击（破坏），英雄认清威胁（认识），与反派战斗（修复），城市得救但英雄已改变（新平衡）。
8. Persuasive Techniques: The AIDA Formula | 说服技巧：AIDA公式
Advertising and many media messages use the AIDA formula to influence audiences: Attention, Interest, Desire, Action. First, grab attention with a bold image or headline, then build interest with relevant features, create desire by appealing to emotions or needs, and finally prompt action with a call to buy or click.
广告和许多媒介信息使用 AIDA 公式来影响受众：注意、兴趣、欲望、行动。首先用醒目的图像或标题吸引注意，然后用相关功能建立兴趣，通过诉诸情感或需求创造欲望，最后以号召购买或点击来推动行动。
Other persuasive devices include rhetorical questions, emotive language, rule of three, and bandwagon appeals. These are like ‘equation shortcuts’ to boost persuasion.
其他说服手段包括反问句、情感语言、三连结构法、从众效应。它们就像是增强说服力的“方程式快捷方式”。
9. Layout & Design: The Z-Pattern Rule | 排版与设计：Z型视线法则
Many posters, web pages, and magazines arrange elements following the Z-pattern: the eye naturally scans a page from top-left to top-right, diagonally down to bottom-left, and across to bottom-right. Designers place the most important information (logo, headline) along this path.
许多海报、网页和杂志按照 Z 型模式排列元素：眼睛自然地沿左上到右上、斜向下到左下、再到右下的路径扫视页面。设计师将最重要的信息（标志、标题）放置在此路径上。
The Rule of Thirds divides an image into nine equal sections; placing key subjects at intersection points creates a balanced, more dynamic composition. These visual formulas make media texts more effective.
三分法将图像分成九个相等的部分；将关键主体放在交叉点上可创造出平衡且更富动感的构图。这些视觉公式使媒介文本更有效。
10. Sound & Music: The Emotional Frequency Theorem | 声音与音乐：情感频率定理
Sound carries meaning through pitch, tempo, and volume. A high-pitched, fast tempo builds excitement or fear, while a low, slow melody suggests sadness or menace. Diegetic sound comes from inside the story world (e.g., characters talking, car engine); non-diegetic sound is added for the audience (e.g., background music, voice-over).
声音通过音高、节奏和音量传递意义。高音调、快节奏能营造兴奋或恐惧，而低沉缓慢的旋律暗示悲伤或威胁。剧情声来自故事世界内部（如角色说话、汽车引擎）；非剧情声则是为观众添加的（如背景音乐、画外音）。
Sound can be thought of as an emotional frequency: sharp, discordant sounds generate tension; harmonious, soft sounds generate comfort. Combining sound with visuals amplifies the intended message.
声音可被视为一种情感频率：尖锐不和谐的声音制造紧张；和谐柔和的声音产生舒适感。将声音与视觉结合能放大预期的信息。
11. Media Institutions: The Production Cycle | 媒介机构：生产周期
Media products are created by institutions such as the BBC, Disney, or independent YouTube channels. The basic production cycle formula is: Pre-production → Production → Post-production → Distribution → Exhibition/Consumption. Understanding this helps you analyse how ownership and processes affect the final text.
媒介产品由 BBC、迪士尼或独立的 YouTube 频道等机构创作。基本的生产周期公式是：前期制作 → 制作 → 后期制作 → 发行 → 放映/消费。理解这一点有助于分析所有权和流程如何影响最终文本。
