1. History & Media: Propaganda Poster Analysis | 历史与媒体：宣传海报分析
Question: Imagine you are studying a 1943 British recruitment poster showing a smiling soldier against a factory backdrop, with the slogan ‘Our Work – Your Courage’. Analyse how the poster uses visual and textual elements to persuade its audience. Refer to historical context in your answer.
问题：想象你正在研究一张 1943 年的英国征兵海报，海报上一位微笑的士兵站在工厂背景前，口号是’我们的工作——你们的勇气’。分析这张海报如何运用视觉和文字元素说服受众，并在回答中提及历史背景。
Start by identifying the historical context. In 1943, Britain was fully mobilised for total war, and the government needed to sustain both industrial output and military recruitment. The poster targets two distinct groups: factory workers and potential soldiers. By pairing ‘Our Work’ with ‘Your Courage’, it creates a bond of mutual duty.
首先要确定历史背景。1943 年，英国已全面动员进行总体战，政府需要维持工业生产并持续征兵。海报针对的是两个不同的群体：工厂工人和潜在的士兵。通过将’我们的工作’与’你们的勇气’配对，它建立了一种相互尽责的纽带。
Visually, the smiling soldier appears heroic but approachable, while the factory chimneys in the background signal productivity. The use of warm, muted colours – khaki, brown, and beige – evokes the military uniform and the workshop, blending the two worlds. The typography is bold and uppercase, reminiscent of official commands, which adds a sense of urgency.
在视觉上，微笑的士兵显得英勇又平易近人，背景中的工厂烟囱则传递出生产力的信号。温暖而沉稳的色调——卡其色、棕色和米色——让人联想到军装和车间，将两个世界融合起来。字体加粗且全部大写，令人联想到官方命令，从而增添紧迫感。
Symbolism plays a key role: the soldier’s raised hand can be interpreted as a salute to the workers, while the factory behind him represents the backbone of the war effort. The slogan’s juxtaposition of pronouns (‘Our’ and ‘Your’) constructs a shared national identity, encouraging every citizen to see their role as vital.
象征手法也起着关键作用：士兵抬起的手可被解读为向工人们的敬礼，而他身后的工厂则代表战争努力的支柱。口号中人称代词（’我们的’和’你们的’）的并列构建了一种共同的国家认同，鼓励每个公民视自己的角色为至关重要。
Key takeaway: When analysing historical media, always link visual and textual choices to the specific events, attitudes, and needs of the time. This shows deep contextual understanding.
关键要点：在分析历史媒体时，务必将视觉和文字的选择与当时的具体事件、态度和需求联系起来。这能展示深刻的语境理解。
2. English & Media: Persuasive Language in Advertisements | 英语与媒体：广告中的说服性语言
Question: A print advert for a new smartphone reads: ‘Unleash tomorrow. Today. The phone that learns your rhythm. Over 15 million satisfied users. Don’t get left behind.’ Identify three persuasive language techniques and explain their effects on the target audience of teenagers.
问题：一则新款智能手机的平面广告写道：’释放明天。就在今天。懂你节奏的手机。超过 1500 万满意用户。别掉队。’找出三种说服性语言技巧，并解释它们对青少年目标受众的影响。
First, the imperative ‘Unleash tomorrow. Today.’ combines a command with a paradox, creating excitement and a call to action. It suggests that the future is attainable immediately, appealing to teenagers’ desire for instant gratification and innovation.
首先，祈使句’释放明天。就在今天。’将命令与矛盾修饰结合，营造出兴奋感和行动号召。它暗示未来可立即实现，贴合青少年对即时满足和创新的渴望。
Second, the phrase ‘the phone that learns your rhythm’ employs personification, giving the device human-like qualities of adaptability and intelligence. This technique makes the product feel personalised and attentive, tapping into teenagers’ need for self-expression and individuality.
其次，’懂你节奏的手机’运用了拟人手法，赋予设备适应性和智能等人类特质。这一技巧让产品感觉个性化且贴心，切合青少年自我表达和个性的需求。
Third, the statistic ‘Over 15 million satisfied users’ is a form of bandwagon appeal, suggesting that because many people already own the phone, the reader should join them to avoid being excluded. The final tagline ‘Don’t get left behind’ reinforces this fear of missing out (FOMO), a powerful motivator among adolescents.
第三，’超过 1500 万满意用户’这一数据是一种从众诉求的形式，暗示因为很多人已经拥有这款手机，读者也应加入以免被排斥。最后的标语’别掉队’强化了错失恐惧症（FOMO），这是青少年中强大的驱动力。
The combination of these techniques works because it addresses both emotional needs (belonging, identity) and cognitive shortcuts (social proof), common in media aimed at young consumers.
这些技巧的结合之所以有效，是因为它同时满足了情感需求（归属感、身份认同）和认知捷径（社会证明），这在针对年轻消费者的媒体中十分常见。
3. Science & Media: Explaining Algorithmic Filter Bubbles | 科学与媒体：解释算法过滤气泡
Question: Draw a simple flowchart to explain how a video-sharing platform’s recommendation algorithm creates a ‘filter bubble’ for a 13-year-old user interested in cooking videos. Use scientific vocabulary such as ‘data input’, ‘pattern recognition’, and ‘positive feedback loop’.
问题：画一个简易流程图，解释视频分享平台的推荐算法如何为一位对烹饪视频感兴趣的 13 岁用户创建一个’过滤气泡’。使用诸如’数据输入’、’模式识别’和’正反馈循环’等科学词汇。
Begin with data input: every time the user watches, likes, or shares a cooking video, the algorithm records these interactions as preference signals. The platform also collects demographic data (age 13) and device information, which become part of the user profile.
从数据输入开始：每当用户观看、点赞或分享一个烹饪视频，算法就会将这些互动记录为偏好信号。平台还收集人口统计数据（年龄 13 岁）和设备信息，这些成为用户画像的一部分。
Next, pattern recognition occurs: the algorithm compares this profile with millions of similar users and identifies clusters – for example, ‘teenagers who enjoy quick recipe tutorials’. It then predicts that the user will engage with more of the same type of content.
接着发生模式识别：算法将此画像与数百万相似用户进行比较，识别出聚类——例如，’喜欢快速食谱教程的青少年’。然后它会预测该用户会与更多同类内容互动。
As the system serves increasingly similar cooking videos, user engagement rises, creating a positive feedback loop: more cooking videos lead to more clicks and longer watch time, which the algorithm interprets as confirmation of interest. Gradually, the user sees fewer and fewer videos on other topics, even if they might have been curious about science or music. The bubble narrows their exposure.
随着系统推送越来越相似的烹饪视频，用户参与度上升，形成一个正反馈循环：更多的烹饪视频带来更多点击和更长的观看时间，算法将此解释为兴趣的确认。渐渐地，用户看到的其他主题视频越来越少，即便他们可能对科学或音乐也曾感到好奇。气泡限制了他们的信息接触。
In your answer, you must show that the filter bubble is not a deliberate censorship but an unintended consequence of optimisation for engagement. Using scientific language demonstrates your understanding of the process as a computational system.
在回答中，必须表明过滤气泡并非刻意审查，而是为优化参与度而产生的意外后果。使用科学语言能够展示你对此过程作为一个计算系统的理解。
4. Geography & Media: Global News Flow and Representation | 地理与媒体：全球新闻流动与呈现
Question: Compare the coverage of a natural disaster in a low-income country and a high-income country using the same international news channel. Discuss ‘news flow’ and ‘representation’, and suggest one reason why the low-income country might receive less airtime.
问题：比较同一家国际新闻频道对发生在低收入国家与高收入国家的一场自然灾害的报道。讨论’新闻流动’和’呈现’，并提出低收入国家可能获得较少播出时间的一个原因。
News flow refers to the direction and volume of media content between regions. Historically, news flows from wealthier, more powerful nations to the rest of the world, while stories from the Global South are often underreported or filtered through a Western lens. In this task, you can note that the news channel is based in a high-income country, which may influence editorial priorities.
新闻流动指的是地区之间媒体内容的流向和数量。历史上，新闻从更富裕、更强大的国家流向世界其他地区，而全球南方的新闻事件往往报道不足或通过西方的视角过滤。在这项任务中，你可以指出该新闻频道总部设在高收入国家，这可能会影响编辑的优先顺序。
For a disaster in a low-income country, coverage might focus on immediate devastation and portray victims as helpless, using generic labels like ‘African flood’ without local context. By contrast, a disaster in a high-income country is likely to feature personal stories, expert analysis, and detailed reconstruction efforts, framing the event as a national challenge to overcome. This is a matter of representation: how groups and places are portrayed, often reinforcing stereotypes.
对于低收入国家的灾难，报道可能聚焦于即时破坏，并将受害者描绘成无助，使用如’非洲洪水’这样的泛化标签而不提供当地背景。相比之下，高收入国家的灾难报道则更可能包含个人故事、专家分析和详细的重建努力，将该事件框定为需要克服的国家挑战。这就是呈现问题：如何描绘群体和地方，往往会强化刻板印象。
A key reason for less airtime could be commercial: the channel’s primary audience is in the high-income country, so it prioritises stories that feel emotionally and geographically closer to them. Additionally, logistical costs and safety concerns in remote regions can reduce reporting capacity.
播出时间较少的一个关键原因可能是商业因素：该频道的主要观众群在高收入国家，因此它优先报道那些在情感和地理上更接近受众的新闻。此外，在偏远地区进行报道的后勤成本和安全顾虑也可能削弱报道能力。
To strengthen your answer, use geographical concepts like ‘distance decay’ (information relevance diminishes with distance) and reflect on how media can shape viewers’ mental maps of the world.
为加强你的答案，可使用地理学概念如’距离衰减’（信息的相关性随距离减弱），并反思媒体如何塑造观众对世界的心理地图。
5. Maths & Media: Interpreting Data Visualisations in the News | 数学与媒体：解读新闻中的数据可视化
Question: A news article includes a bar chart showing ‘Average Daily Screen Time (hours)’ for four age groups: 8-11 (2.5 h), 12-15 (4.2 h), 16-18 (5.1 h), 19-24 (5.8 h). The y-axis starts at 2, not zero. Explain how this choice could mislead a reader, and calculate the percentage increase from the 8-11 group to the 19-24 group.
问题：一篇新闻文章包含一幅柱状图，显示四个年龄组的’平均每日屏幕时间（小时）’：8-11 岁（2.5 小时）、12-15 岁（4.2 小时）、16-18 岁（5.1 小时）、19-24 岁（5.8 小时）。纵轴起点为 2，而非 0。解释这种选择会如何误导读者，并计算 8-11 岁组到 19-24 岁组的百分比增长。
When the y-axis does not start at zero, the visual difference between bars appears exaggerated. A bar representing 2.5 hours will look less than half the height of the bar for 5.8 hours even if the actual ratio is about 2.3:1. The truncation makes the gap seem more dramatic, a common media technique to emphasise a trend. Readers who glance quickly may perceive a crisis of rising screen time among young adults.
当纵轴不从零开始时，柱状之间的视觉差异会被夸大。代表 2.5 小时的柱子看起来不到 5.8 小时柱子高度的一半，而实际比例大约是 2.3:1。截断纵轴使差距显得更惊人，这是媒体用来强调趋势的常见技巧。快速扫视的读者可能会认为年轻人屏幕时间的增长已形成危机。
To find the percentage increase: subtract the original value (2.5) from the new value (5.8) to get 3.3. Then divide by the original value: 3.3 ÷ 2.5 = 1.32. Multiply by 100 to obtain 132%. So the average daily screen time for 19-24-year-olds is 132% higher than that of 8-11-year-olds. A less misleading way to present the data would be to start the y-axis at zero and show the true proportions, or to accompany the chart with exact figures and a note explaining variability.
计算百分比增长：用新数值（5.8）减去原数值（2.5）得到 3.3。然后除以原数值：3.3 ÷ 2.5 = 1.32。乘以 100 得到 132%。因此 19-24 岁年龄组的平均每日屏幕时间比 8-11 岁组高 132%。一种不易产生误导的呈现方式是让纵轴从零开始并显示真实比例，或是在图表旁附上精确数字并附注解释变异性。
Always check axes scales, source of data, and sample sizes when interpreting media statistics. A quick mental calculation can protect you from being misled.
在解读媒体统计数据时，务必检查轴刻度、数据来源和样本容量。快速的心算可以帮助你避免被误导。
6. Art & Media: Visual Composition in Film Posters | 艺术与媒体：电影海报的视觉构图
Question: Refer to a film poster of your choice (describe it) and analyse how the rule of thirds, colour palette, and typography create a mood and inform the audience about the genre. You may imagine a poster for a science-fiction adventure.
问题：选择一张你喜欢的电影海报（描述它），分析三分法构图、色彩搭配和字体如何营造氛围并告知观众影片的类型。你可以想象一张科幻冒险电影海报。
Imagine a poster for a sci-fi film called ‘Nebula Drift’. The main character, a young astronaut, is placed along the right vertical third, looking leftward towards an alien galaxy that fills the upper-left intersection point. This use of the rule of thirds leaves the remaining space for the swirling nebula and a distant spacecraft, creating a dynamic and balanced composition. The character’s gaze leads the viewer’s eye across the poster.
想象一张名为’星云漂流’的科幻电影海报。主角是一位年轻宇航员，被放置在右侧的竖向三分线上，面朝左方，望向占据左上交点的一个外星银河。这种三分法的运用将剩余空间留给旋转的星云和远处的太空船，创造出动态而平衡的构图。角色的视线引导观众的目光扫过整个海报。
The colour palette uses deep purples, electric blues, and neon pinks, which are classic sci-fi signifiers associated with cosmic phenomena and advanced technology. The contrast between the dark background and the bright central elements creates a sense of mystery and wonder. Typography matters too: the title ‘Nebula Drift’ is rendered in a sleek, metallic sans-serif font, while the tagline ‘Beyond the known light’ appears in a smaller, italicised serif style, adding a literary, epic quality.
色彩搭配使用了深紫色、电光蓝和霓虹粉，这些是经典的科幻符号，与宇宙现象和先进科技相关。深色背景与明亮中心的对比营造出神秘与惊奇感。字体也很重要：片名’星云漂流’采用光滑的金属质感无衬线字体，而标语’已知之光之外’则以较小的斜体衬线字体呈现，增添了文学性与史诗感。
All these visual elements work together to signal the genre immediately, even without reading the plot. A media literate viewer can ‘read’ the poster for information about theme, target audience, and emotional tone.
所有这些视觉元素共同作用，能够让人无需阅读剧情简介就立刻识别出电影类型。一个具有媒体素养的观众可以’阅读’海报，获取关于主题、目标受众和情感基调的信息。
7. Psychology & Media: Emotional Appeals in Charity Advertisements | 心理学与媒体：慈善广告中的情感诉求
Question: A charity campaign video shows a single child in a damaged school, with slow, sombre piano music and a voiceover saying, ‘She is waiting for someone to rewrite her story.’ Using concepts like ‘sympathy’, ‘guilt’, and ‘hope’, explain how the advert aims to influence donation behaviour.
问题：一段慈善活动视频展示了一名身处受损学校中的儿童，配以缓慢而沉郁的钢琴音乐，画外音说道：’她在等待某人为她重写故事。’运用’同情’、’内疚’和’希望’等概念，解释该广告如何意图影响捐赠行为。
Psychology tells us that emotional appeals often bypass rational processing and trigger immediate responses. The advert first evokes sympathy by focusing on a single identifiable victim – a technique known as the ‘identifiable victim effect’. Seeing one child in distress creates a stronger emotional reaction than statistics about thousands, because our brains are wired to respond to individual stories.
心理学告诉我们，情感诉求往往能绕过理性处理并触发即时反应。该广告首先通过聚焦于一位可识别的受害者来唤起同情——这一技巧被称为’可识别受害者效应’。看到一个处于困境中的孩子，会比看到成千上万的统计数据引发更强烈的情感反应，因为我们的大脑天生就会回应个体的故事。
Secondly, the sombre music and the damaged setting generate a subtle feeling of guilt in the viewer, especially in relatively privileged audiences. The voiceover phrase ‘rewrite her story’ implies that her current narrative is unjust, and that the viewer has the power to change it. This guilt, if not overwhelming, can be a powerful motivator for prosocial action.
其次，沉郁的音乐和被破坏的场景会在观众心中产生隐隐的内疚感，尤其是对于相对优越的观众。画外音中的’重写她的故事’暗示她当前的经历是不公的，而观众拥有改变它的力量。这种内疚感如果不至于过度强烈，就可能成为推动亲社会行为的强大动力。
Finally, the advert ends with a glimpse of possibility – perhaps a shot of books and a rebuilt classroom – injecting a sense of hope and agency. The combination of sympathy, guilt, and hope is a classic triad in charity advertising. It moves the audience from passive sadness to an active desire to help, making a donation feel like a meaningful, personal action.
最后，广告以一丝可能性的镜头收尾——或许是一闪而过的书本和重建的教室——注入了一种希望和能动感。同情、内疚与希望的三合一，是慈善广告中的经典组合。它将观众从被动的悲伤引向主动帮助的意愿，让捐款行为感觉像是一项有意义的个人行动。
When analysing such media, identify the sequence of emotions and link each to a psychological principle to demonstrate deeper insight.
在分析此类媒体时，要识别情感的递进顺序，并将每一种情绪与心理学原理联系起来，以展现更深刻的见解。
8. Ethics & Media: Privacy in News Reporting | 伦理与媒体：新闻报道中的隐私
Question: A news website publishes the full name and photograph of a teenager who witnessed a serious crime, despite the teen’s family asking for anonymity. Discuss the ethical dilemma using the concepts of ‘public interest’, ‘duty of care’, and ‘minors’ rights’.
问题：一家新闻网站公布了一名目睹严重犯罪的青少年的全名和照片，尽管这名青少年的家人要求匿名。运用’公共利益’、’注意义务’和’未成年人权利’等概念讨论其中的伦理困境。
The core conflict is between the public’s right to know and the individual’s right to privacy, especially for a minor. Ethical journalism requires balancing public interest – the story’s value to society, such as raising awareness about crime – with the duty of care towards vulnerable individuals. Publishing the teenager’s identity may expose them to trauma, bullying, or even retaliation from those connected to the crime.
核心冲突在于公众的知情权与个人隐私权之间，尤其是当涉及未成年人时。合乎伦理的新闻报道要求在公共利益——该事件对社会的价值，如提高对犯罪的关注——与对弱势个体的注意义务之间取得平衡。公布该青少年的身份可能会使其受到创伤、欺凌，甚至遭到与犯罪相关者的报复。
Most professional codes of ethics (such as the NUJ or IPSO guidelines) state that journalists should not identify minors involved in crime stories without exceptional justification. Even if the teenager is a witness and not a suspect, naming them can violate the principle of minimising harm. The family’s request for anonymity should carry significant weight because guardians are in the best position to assess the risk to their child.
大多数专业伦理准则（如 NUJ 或 IPSO 指南）规定，除非有特殊理由，记者不应披露涉及犯罪报道的未成年人的身份。即使该青少年是目击者而非嫌疑人，公开其姓名也可能违反最小伤害原则。家属提出的匿名请求应具有相当的份量，因为监护人最能评估孩子面临的风险。
To argue for publication, one might claim that the teen is a key figure and the story needs authenticity. However, this is rarely sufficient to override the protection owed to children. A responsible media outlet could report the facts without naming the individual, for instance, using ‘a teenage witness’ instead.
要为公开身份做辩护，可能会声称该青少年是关键人物，且报道需要真实性。然而，这通常不足以推翻对儿童的保护义务。一家负责任的媒体机构可在不公开姓名的情况下报道事实，例如使用’一名青少年目击者’的说法。
In your answer, always acknowledge both sides and reach a reasoned conclusion using ethical frameworks like deontology (duty-based) or consequentialism (outcome-based).
在你的回答中，务必承认双方观点，并运用道义论（基于义务）或结果论（基于后果）等伦理框架得出合理的结论。
9. Economics & Media: Business Models and Content Decisions | 经济学与媒体：商业模式与内容决策
Question: A streaming platform relies on subscription revenue, while a free news app earns money solely from advertising. Explain how these two business models might affect the type of content produced for a Year 8 audience. Use terms such as ‘clickbait’, ‘paywall’, and ‘audience segmentation’.
问题：某流媒体平台依赖订阅收入，而一款免费新闻应用仅通过广告盈利。解释这两种商业模式会如何影响面向 Year 8 受众的内容类型。使用诸如’标题诱饵’、’付费墙’和’受众细分’等术语。
The subscription-based platform must attract and retain paying users, so its content for 13-year-olds tends to be high-quality, ad-free, and often educational or premium serialised dramas. Because revenue comes directly from users, the platform prioritises engagement and satisfaction over maximum clicks. It may offer little to no clickbait, as misleading titles would damage trust and cause cancellations.
基于订阅的平台必须吸引并留住付费用户，因此其为 13 岁孩子提供的内容往往质量较高、无广告，且通常是教育类或优质的系列剧。由于收入直接来自用户，平台优先考虑的是参与度和满意度，而非点击量的最大化。它可能很少或根本不会使用标题诱饵，因为误导性标题会破坏信任并导致用户退订。
In contrast, the ad-supported free news app earns revenue every time a page is viewed or an ad is displayed. This model incentivises high volumes of traffic, so content producers may use sensational headlines, viral quizzes, or emotionally charged stories to attract clicks – this is classic clickbait. For a Year 8 audience, this might mean an excess of celebrity gossip, misleading quick tips, or alarming simplified news that grabs attention but lacks depth.
相比之下，靠广告支持且免费的新闻应用，每次页面浏览或展示广告都能产生收入。这种模式激励的是高流量，因此内容生产者可能会使用耸人听闻的标题、病毒式小测试或情绪化的故事来吸引点击——这就是典型的标题诱饵。对于 Year 8 受众来说，这可能意味着充斥着名人八卦、误导性的速成技巧，或缺乏深度但能博人眼球的简化新闻。
Audience segmentation is also affected: the subscription service can afford to target niche interests (e.g., a whole channel dedicated to science) because it only needs to satisfy its subscribers, while the free app must appeal to the broadest possible audience to maximise ad impressions, which often results in a ‘race to the bottom’ in terms of quality.
受众细分也受影响：订阅服务可以针对小众兴趣（例如，一整个科学频道）进行创作，因为它只需要满足其订阅者；而免费应用则必须迎合尽可能广泛的受众以最大化广告展现量，这往往会导致质量上的’逐底竞争’。
Understanding the economics behind media helps you become a more critical consumer who can recognise why certain content is being promoted.
理解媒体背后的经济学有助于你成为更有批判力的消费者，能够识别某些内容被推送背后的原因。
10. Law & Media: Copyright and Fair Use in School Projects | 法律与媒体：学校项目中的版权与合理使用
Question: You are creating a video for a class project and want to use a 20-second clip from a popular movie and a chart from a news website. Explain whether each use is likely to be considered ‘fair use’ or ‘fair dealing’ under UK law, and what steps you should take to respect copyright.
问题：你正在为课堂项目制作一个视频，想使用一段流行电影的 20 秒片段和一张新闻网站的图表。根据英国法律，解释每种使用情形是否可能被视为’公平使用’或’公平交易’，以及你应该采取哪些步骤来尊重版权。
Under UK copyright law, ‘fair dealing’ allows limited use of copyrighted material for certain purposes including research, private study, criticism, review, and news reporting – and importantly, for the purposes of instruction in an educational context. For the film clip, you must ask: is the amount taken (20 seconds) reasonable relative to the length of the whole work, and is it truly for educational illustration? A 20-second clip in a classroom presentation probably qualifies, especially if you add your own commentary or analysis and are not sharing it publicly for profit.
根据英国版权法，’公平交易’允许为某些特定目的有限度地使用受版权保护的材料，包括研究、私人学习、批评、评论和新闻报道，且重要的是，可用于教学目的。对于电影片段，你必须问：所取用的 20 秒相对于整个作品的长度是否合理，以及它是否确实用于教育说明？在课堂演示中使用 20 秒的片段很可能符合要求，特别是如果你添加了自己的评论或分析，并且不将其公开以获利。
The chart from a news website is a different type of work – a graphic or data visualisation. Charts often contain factual data, which is not copyrighted, but the specific presentation (choice of colours, layout) may be protected. To stay safe, you should redraw the chart using the same underlying data but your own design, or cite the source clearly and use a small, low-resolution version. Creating a transformative work, such as incorporating the chart into a larger educational narrative, also strengthens a fair dealing claim.
新闻网站的图表则属于另一种类型的作品——图形或数据可视化。图表通常包含不受版权保护的事实数据，但其特定的呈现方式（颜色选择、布局）可能受到保护。为稳妥起见，你应该使用相同的基础数据但以自己的设计重新绘制图表，或者清晰标明出处并使用小尺寸、低分辨率的版本。创作具有转换性质的作品，例如将图表融入一个更大的教育叙事中，也能增强公平交易的主张。
Always provide attribution: ‘Source: [website name], date accessed.’ For school projects, teachers will expect you to respect intellectual property and to demonstrate that you understand the difference between legal use and infringement.
务必提供出处：’来源：[网站名称]，[访问日期]。’在学校项目中，老师期望学生尊重知识产权，并展示出理解合法使用与侵权之间区别的能力。
