1. Understanding the Essay Question | 理解论文题目
Before you write a single word, spend two minutes reading the question carefully. Circle the command word – this tells you what to do. In Year 7, the most common command words are ‘explain’, ‘describe’, ‘analyse’ and ‘evaluate’. Next, underline the economic concepts mentioned, such as ‘demand’, ‘scarcity’, ‘opportunity cost’ or ‘price’. This simple habit keeps your answer relevant and stops you from drifting off‑topic.
在写下任何一个字之前，花两分钟仔细阅读题目。圈出指令词——它告诉你该做什么。在七年级，最常见的指令词是“解释”、“描述”、“分析”和“评估”。然后，在提到的经济学概念下划线，比如“需求”、“稀缺性”、“机会成本”或“价格”。这个简单的习惯能让你的答案切题，避免跑题。
For example, if the question says “Explain how a rise in the price of a good affects its demand”, your job is to give reasons and show the cause‑and‑effect chain. You are not expected to present arguments for and against, unless the question uses ‘evaluate’. Always match the depth of your writing to the command word.
例如，如果问题是“解释一种商品的价格上升如何影响其需求”，你的任务就是给出原因，展示因果链条。题目没有要求你呈现正反两方面的论点，除非使用了“评估”这个词。始终让你的写作深度与指令词匹配。
2. The PEEL Paragraph Structure | PEEL 段落结构
For every paragraph in the body of your essay, use the PEEL model: Point, Evidence, Explanation and Link. This structure keeps your writing logical and exam‑friendly. Start with a clear Point that answers the question directly. Then provide Evidence, which could be a real‑world example, a data reference or an economic law. Follow that with an Explanation – use ‘because’, ‘this means that’, ‘as a result’ to show the links. Finally, add a Link sentence to connect back to the question or lead into the next paragraph.
在论文的主体部分，每一段都使用 PEEL 模型：观点、证据、解释和连接。这个结构能让你的写作富有逻辑，且便于阅卷。以直接回答问题的明确观点开头。然后提供证据，可以是现实例子、数据参考或经济规律。接着是解释——使用“因为”、“这意味着”、“结果是”来展示联系。最后，加上一个连接句，回扣题目或引出下一段。
- Point: “An increase in price causes a contraction in demand.”
- Evidence: “For instance, when train fares rise during peak hours, some commuters switch to buses.”
- Explanation: “Higher prices reduce people’s real income, so they look for cheaper alternatives.”
- Link: “Therefore, price changes play a key role in allocating resources.”
PEEL 的每个字母代表：观点——“价格上升导致需求量收缩”；证据——“例如，高峰时段火车票价上涨时，一些通勤者改乘巴士”；解释——“更高的价格降低了人们的实际收入，因此他们寻找更便宜的替代品”；连接——“因此，价格变化在资源配置中起关键作用”。
3. Writing a Strong Introduction | 写好引言
Your introduction should be two to three sentences. Begin by defining the key economic terms in the question. Then state your argument or outline the structure of your essay. Avoid long, sweeping statements like “Economics is a very important subject”. Get straight to the point.
你的引言应该有两到三句话。首先，定义题目中的关键经济学术语。然后，陈述你的论点或概述文章结构。避免冗长空泛的表述，如“经济学是一门非常重要的学科”。直接进入正题。
Example: “Opportunity cost refers to the value of the next best alternative forgone. This essay will explain why scarcity makes opportunity cost a central concept for consumers and producers alike.”
举例：“机会成本是指所放弃的次优选择的价值。本文将解释为什么稀缺性使机会成本成为消费者和生产者共同的核心概念。”
4. Developing Arguments: Point and Explanation | 展开论点：观点与解释
In economics essays, stating a point is only the start. You must also explain the why and how. Use economic reasoning: show the chain of events step‑by‑step. For example, “When costs of production rise, supply shifts to the left (S1 → S2) because at every price, firms are less willing to produce.” The best answers tell a clear story with cause and effect.
在经济学论文中，提出观点只是开始。你必须解释“为什么”和“如何”。使用经济学推理：逐步展示事件链条。例如，“当生产成本上升时，供给曲线向左移动（S1 → S2），因为在每个价格水平上，企业的生产意愿都降低了。”最优答案讲述的是一个清晰的因果故事。
Consider using simple diagrams in your mind and describing them in words. Even if you are not asked to draw, phrases like “the supply curve shifts to the right, leading to a lower equilibrium price and higher quantity” demonstrate understanding of market mechanics.
你可以在脑海中构思简单图表并用文字描述。即使题目不要求画图，像“供给曲线向右移动，导致均衡价格下降、均衡数量增加”这样的表述也能体现你对市场机制的理解。
5. Using Economic Terminology | 使用经济学术语
Accurate terminology signals that you are thinking like an economist. Instead of saying “people want less of something”, use “quantity demanded contracts”. Replace “things we need” with “needs and wants”. Use words like scarce resources, opportunity cost, market equilibrium, incentives, specialisation and factors of production. Remember to spell them correctly and use them in the right context.
准确使用术语表明你在像经济学家一样思考。与其说“人们想要更少的东西”，不如说“需求量收缩”。把“我们需要的东西”替换为“需要与欲望”。使用诸如稀缺资源、机会成本、市场均衡、激励、专业化和生产要素等词汇。注意拼写正确，并在恰当的语境中使用。
However, do not throw in jargon just to sound clever. Every term must carry meaning. If you use elastic demand, you must explain that it means quantity demanded changes significantly when price changes. Quality over quantity always wins.
不过，不要只是为了听起来聪明而堆砌术语。每个术语都必须有意义。如果你使用了弹性需求，就必须解释它意味着当价格变化时，需求量变化显著。质量永远胜过数量。
6. Incorporating Examples and Evidence | 引用例子和证据
Real‑world examples make your essay convincing and memorable. Year 7 topics fit perfectly with examples from daily life: pocket money choices, changes in canteen prices, the cost of a new video game, or a local shop offering a discount. A well‑chosen example counts as evidence and supports your point.
现实例子能让你的论文更有说服力，更令人印象深刻。七年级的课题非常适合使用日常生活中的例子：零用钱的使用选择、食堂价格的变化、新电子游戏的价格或者附近商店的打折活动。一个精心选取的例子就是证据，能够支撑你的观点。
For instance, when explaining opportunity cost, write: “If you have £10 and choose a cinema ticket instead of a book, the opportunity cost is the enjoyment and knowledge you would have gained from reading the book.” This makes abstract ideas concrete for your reader.
例如，在解释机会成本时，你可以写：“如果你有 10 英镑，选择了电影票而非一本书，那么机会成本就是你在阅读那本书时本可获得的乐趣和知识。”这能把抽象的概念具象化，便于读者理解。
7. Evaluating and Concluding | 评估与结论
In longer essays, or when the command word is ‘evaluate’, you need to weigh up arguments and make a judgement. You might say: “Although higher prices may reduce demand, this depends on the type of good. For essential items like bread, demand does not change much.” This shows you understand that economic effects are not always straightforward.
在较长的论文中，或者当指令词是“评估”时，你需要权衡不同论点并作出判断。你可以说：“虽然更高的价格可能会减少需求，但这取决于商品的种类。对于面包等必需品，需求变化不大。”这体现你理解经济效应并非总是直截了当的。
Your conclusion should summarise your main argument without repeating every detail. Restate your judgement and link back to the question. A strong conclusion: “In conclusion, while rising costs can push up prices in the short run, sustained price increases depend on whether demand remains stable. Therefore, supply‑side shocks alone do not guarantee permanent inflation.”
结论应总结主要论点，但不要重复每个细节。重申你的判断并呼应题目。一个有力的结论是：“总之，虽然成本上升可能在短期内推高价格，但持续的价格上涨取决于需求是否保持稳定。因此，仅靠供给冲击不一定会导致永久性通胀。”
8. Common Mistakes to Avoid | 需要避免的常见错误
- Not answering the question: Writing everything you know about a topic without focusing on the exact wording of the question. Always read back and ask yourself, ‘Does this sentence answer the question?’
- 未回答问题：把自己对某个课题所知的一切都写出来，却忽略了题目的确切措辞。一定要回读，并问自己：“这句话回答题目了吗？”
- Listing facts without explanation: Essays require analysis. If you write “Demand is the amount consumers buy”, follow it up with why that happens or what makes it change.
- 只罗列事实而无解释：论文需要分析。如果你写了“需求就是消费者购买的数量”，接下来一定要解释这种情况发生的原因或什么因素会导致它变化。
- Weak or no examples: Even the simplest example adds strength. Try to include one example for every two paragraphs.
- 例子薄弱或缺少例子：哪怕是最简单的例子也能增强说服力。试着每两段就加入一个例子。
- Overcomplicating language: Plain, precise English always beats messy, overblown sentences.
- 语言过于复杂：简洁、精准的英语永远比杂乱、浮夸的句子更好。
9. Sample Essay 1: Demand and Supply | 范文1：需求与供给
Question: “Explain how a decrease in supply affects the equilibrium price and quantity in the market for coffee.”
题目：“解释供给减少如何影响咖啡市场的均衡价格和均衡数量。”
A decrease in supply means that at every price, producers are willing and able to offer less coffee for sale. This is often caused by higher costs of production, such as poor harvests or rising wages for coffee pickers. On a supply and demand diagram, the supply curve shifts to the left from S₁ to S₂.
供给减少意味着在每个价格水平上，生产者愿意且能够出售的咖啡数量都变少了。这通常是由生产成本上升引起的，比如收成不佳或咖啡采摘工人的工资上涨。在供需图中，供给曲线从 S₁ 向左移动到 S₂。
When supply falls and demand remains unchanged, a shortage is created at the original equilibrium price. Consumers compete for the limited coffee, which pushes the market price up. As the price rises, some consumers reduce their quantity demanded – this is a contraction of demand. At the same time, higher prices signal to producers to supply slightly more than they would at lower prices, but the overall quantity is still lower than before.
当供给减少而需求不变时，在原来的均衡价格上会出现短缺。消费者竞相购买有限的咖啡，从而推高了市场价格。随着价格上涨，一些消费者会减少他们的需求量——这就是需求的收缩。与此同时，高价也向生产者发出信号，使他们愿意比在低价时多供给一些，但总体数量仍然低于之前。
The new equilibrium settles at a higher price (P₂) and a lower quantity (Q₂) compared with the original equilibrium (P₁, Q₁). Therefore, a decrease in supply leads to higher prices and reduced trade volume in the coffee market. In the real world, this explains why a drought in coffee‑growing regions makes your cappuccino more expensive.
与原来的均衡（P₁，Q₁）相比，新的均衡稳定在更高的价格（P₂）和更低的数量（Q₂）上。因此，供给减少导致咖啡市场价格上涨和交易量下降。在现实中，这也解释了为什么咖啡种植区的干旱会让你的卡布奇诺变得更贵。
Supply ↓ (S₁ → S₂) → Price ↑ & Quantity ↓
供给 ↓ (S₁ → S₂) → 价格 ↑ & 数量 ↓
10. Sample Essay 2: Scarcity and Choice | 范文2：稀缺性与选择
Question: “Explain why scarcity forces individuals, firms and governments to make choices. Use examples to support your answer.”
题目：“解释为什么稀缺性迫使个人、企业和政府做出选择。用例子支持你的答案。”
Scarcity is the fundamental economic problem: there are finite resources but unlimited wants. Because we cannot have everything we desire, every choice involves an opportunity cost. This principle applies at all levels of the economy.
稀缺性是根本的经济学问题：资源是有限的，而欲望是无限的。正因为我们无法拥有自己想要的一切，每一个选择都包含着机会成本。这一原则适用于经济的各个层面。
For an individual, scarcity appears in daily decisions. A student with £5 can either buy a sandwich or a magazine. The opportunity cost of the sandwich is the magazine she forgoes. Because money is limited, she must rank her preferences and make a choice. Similarly, a firm faces scarcity of labour and capital. If a bakery decides to produce more bread, it may have to use ovens and workers that could have been making cakes. The opportunity cost of bread is the cakes it could have baked instead.
对个人而言，稀缺性体现在日常决策中。一名学生拿着 5 英镑，可以买一个三明治或一本杂志。选择三明治的机会成本就是她放弃的杂志。因为金钱有限，她必须对偏好排序并做出选择。同样，一家企业面临劳动力和资本的稀缺。如果一家面包店决定生产更多面包，就可能要使用原本可以制作蛋糕的烤箱和工人。生产面包的机会成本就是它本可以烤制的蛋糕。
Governments, too, must choose how to allocate tax revenue. If a council spends £2 million on a new sports centre, the opportunity cost might be fewer libraries or lower spending on healthcare. Every decision involves a trade‑off. Scarcity therefore forces all decision‑makers to consider what they value most and to bear the cost of their choices.
政府同样必须选择如何分配税收收入。如果市政厅花费 200 万英镑建一座新的体育中心，其机会成本就可能是更少的图书馆或更低的医疗支出。每个决策都涉及权衡。因此，稀缺性迫使所有决策者考虑他们最看重的是什么，并承担其选择所带来的代价。
In conclusion, scarcity is unavoidable, and it makes the study of opportunity cost essential. By recognising that every ‘yes’ to one option is a ‘no’ to another, individuals, firms and governments learn to allocate resources more wisely.
总之，稀缺性不可避免，它使机会成本的研究变得至关重要。认识到对一种选择说“是”就意味着对其他选项说“不”，个人、企业和政府才能学会更加明智地配置资源。
11. Marking Criteria and Self‑Assessment | 评分标准与自我评估
Understanding how your essay is judged will help you target higher marks. Although Year 7 rubrics vary, most Edexcel‑style essays are marked on four areas: knowledge and understanding, application, analysis and evaluation.
了解论文的评判方式有助于你瞄准更高分数。虽然七年级的评分标准各有不同，但大多数 Edexcel 风格的论文都从四个方面打分：知识与理解、应用、分析和评估。
| Assessment Objective | What it means | Self‑check question |
|---|---|---|
| Knowledge | Have I used accurate definitions and terminology? | Did I define key terms like ‘scarcity’? |
| Application | Have I linked theory to real‑world examples? | Does my essay include a relevant example? |
| Analysis | Have I explained cause‑and‑effect chains? | Did I show step‑by‑step economic reasoning? |
| Evaluation | Have I considered different viewpoints or made a judgement? | Did my conclusion weigh up arguments? |
评估目标与自我检查问题对照表：知识——我是否使用了准确的定义和术语？应用——我是否将理论与现实例子联系起来？分析——我是否解释了因果链条？评估——我是否考虑了不同观点或做出了判断？
12. Conclusion and Final Tips | 总结与最后提示
Mastering essay writing in Year 7 Economics is about practice and structure, not innate talent. Start every answer by dissecting the question, plan three to four PEEL paragraphs, and never forget to include examples. Write in clear, straightforward English and check your work for spelling of economic terms.
在七年级经济学中掌握论文写作，靠的是练习和方法，而非天赋。每道题都从拆解题目开始，计划三到四个 PEEL 段落，并永远不要忘记加入例子。用清晰、直白的英语写作，并检查经济学术语的拼写。
Remember that teachers look for economic thinking, not long‑winded stories. If you can explain ‘why’ behind every change you describe, you will already be on your way to top marks. Use the two model essays in this guide as templates, adapt them to different topics and build your confidence with timed practice.
记住，老师想看到的是经济学思维，而不是长篇大论的故事。如果你能解释你描述的每一个变化背后的“为什么”，你就已经在通往高分的路上了。将本指南中的两篇范文作为模板，根据不同课题进行调整，并通过限时练习建立信心。
