1. Media Language: Signs and Codes | 媒体语言：符号与编码

Media language is the way media texts communicate meaning through a system of signs and codes. A sign consists of two parts: the signifier (the physical form, such as a word, image, or sound) and the signified (the mental concept it represents).

媒体语言是媒体文本通过符号和编码系统传达意义的方式。一个符号由两部分组成：能指（物理形式，如文字、图像或声音）和所指（所代表的心理概念）。

Codes are sets of rules that we recognise and use to decode meaning. Technical codes include camera angles, lighting, and editing. Symbolic codes include objects, colours, and body language. Written codes involve captions, headlines, and typography.

编码是我们识别并用来解码意义的一套规则。技术编码包括摄影角度、灯光和剪辑。象征编码包括物体、颜色和肢体语言。文字编码包括标题、头条和字体排版。

For example, a red heart emoji uses a symbolic code: the heart shape (signifier) signifies love or affection (signified). Understanding these codes helps us read media texts more critically.

例如，一个红色的心形表情符号使用了象征编码：心形（能指）代表爱或情感（所指）。理解这些编码有助于我们更批判性地解读媒体文本。

2. Denotation and Connotation | 外延与内涵

Denotation is the literal or dictionary meaning of a sign – what you actually see or hear. For example, a poster showing a family having dinner denotes exactly that: a family eating a meal together.

外延是符号的字面或字典意义，即你实际看到或听到的内容。例如，一张展示家庭聚餐的海报的外延就是：一家人在一起吃饭。

Connotation refers to the associated meanings, emotions, or ideas that a sign evokes. Using the same dinner poster, the connotation might be warmth, happiness, or family unity. Connotations can differ depending on cultural context.

内涵是指符号引发的关联意义、情感或想法。同样那张聚餐海报，其内涵可能是温暖、快乐或家庭团结。内涵会因文化背景而异。

Analysing both denotation and connotation is a key skill: first describe what you see (denotation), then explain what it suggests or implies (connotation). This allows deeper interpretation of media messages.

分析外延和内涵是一项关键技能：首先描述你所见（外延），然后解释它暗示或隐含了什么（内涵）。这就能更深入地解读媒体信息。

3. Camera Shots and Angles | 摄影机位与角度

Camera shots frame the subject in different ways, each creating a specific effect. An extreme close-up (ECU) focuses on a small detail, like an eye, to show intense emotion. A close-up (CU) shows a character’s face, conveying their feelings. A medium shot (MS) frames the subject from the waist up, often used for dialogue. A long shot (LS) shows the full body, establishing the subject’s environment. An extreme long shot (ELS) captures a vast landscape, making human figures seem small.

摄影镜头以不同方式框取主体，每种都产生特定效果。极端特写聚焦于小细节（如眼睛）以表现强烈情感。特写展示人物面部，传达其感受。中景从腰部以上框取主体，常用于对话。全景显示全身，交代主体环境。极端远景捕捉广阔风景，使人物显得渺小。

Camera angles also influence meaning. A high-angle shot looks down on the subject, making it appear weak or vulnerable. A low-angle shot looks up, making the subject seem powerful or dominant. An eye-level shot is neutral, creating a sense of equality.

摄影角度也影响意义。俯拍从高处向下拍摄主体，使其显得弱小或脆弱。仰拍从低处向上拍摄，使主体显得强大或有支配力。平视角度是中性的，营造平等感。

Combining shot types and angles allows media producers to guide the audience’s attention and feelings. For example, a low-angle close-up of a villain can make them look menacing.

镜头类型与角度的结合使媒体制作者能够引导观众的注意力和感受。例如，反派的低角度特写可使其显得更具威胁性。

4. Editing and Transitions | 剪辑与转场

Editing is the process of selecting and combining shots to create sequences. The pace of editing – fast or slow – sets the rhythm and mood. Quick cuts are used in action scenes to build excitement; long takes in dramas can create tension or realism.

剪辑是选择和组合镜头以创造序列的过程。剪辑节奏——快或慢——设定节奏和情绪。快切用于动作场景以营造兴奋感；戏剧中的长镜头可营造紧张或真实感。

Continuity editing is the standard style, aiming to make cuts invisible so the story flows seamlessly. Techniques like shot/reverse shot (between two characters) and match on action maintain spatial and temporal coherence.

连续性剪辑是标准风格，旨在使剪切不着痕迹，让故事流畅进行。正反打（两个角色之间的镜头切换）和动作匹配等技术保持了空间和时间的一致性。

Transitions are the way one shot moves to the next. A straight cut is abrupt; a fade to black often signals the end of a scene or passage of time; a dissolve blends two shots, suggesting a connection or flashback. A wipe moves one shot across the screen, used for dramatic effect.

转场是一个镜头切换至下一个镜头的方式。直切是突然的切换；淡入黑常表示场景结束或时间流逝；溶解将两个镜头混合，暗示联系或闪回。划像将一个镜头推过屏幕，用于戏剧效果。

5. Sound in Media | 媒体中的声音

Sound in media is divided into diegetic and non-diegetic sound. Diegetic sound comes from within the story world: dialogue, footsteps, a car engine. Characters and audience can hear it. Non-diegetic sound is added for the audience only: background music, voice-over narration, sound effects like a dramatic sting.

媒体声音分为画内音和画外音。画内音来自故事世界内：对话、脚步声、汽车引擎声。角色和观众都能听到。画外音仅为观众添加：背景音乐、画外音叙述、戏剧性 sting 等音效。

Sound has many functions. Dialogue advances the plot. Sound effects create realism or emphasise actions. Music establishes mood, builds tension, or signals emotions (e.g. a heroic theme). Ambient sound (background noise like wind, traffic) sets the scene.

声音有多种功能。对话推动情节。音效营造真实感或强调动作。音乐确立情绪、营造紧张感或暗示情感（如英雄主题）。环境音（如风声、交通背景声）设定场景。

Analysing sound: ask whether it is diegetic or non-diegetic, what it contributes to the narrative, and how it makes the audience feel. Well-designed sound is often unnoticed but profoundly affects the viewing experience.

分析声音：问它是画内音还是画外音，它对叙事有何贡献，以及它让观众有何感受。精心设计的声音常不为人注意，但深刻影响观看体验。

6. Mise-en-scène | 场面调度

Mise-en-scène is a French term meaning ‘put in the scene’. It refers to everything visible in the frame: setting, costume, props, lighting, and actors’ performance. All these elements are carefully chosen to convey meaning.

场面调度（Mise-en-scène）是法语术语，意为“置于场景中”。它涉及画面中可见的一切：场景、服装、道具、灯光和演员表演。所有这些元素都经过精心选择以传达意义。

Setting and props can establish time, place, and social context. For instance, a cluttered classroom with old textbooks can suggest a deprived school
