1. Introduction to Essay Writing in Year 7 Economics | 七年级经济论文写作介绍
Essay writing in Year 7 Economics is designed to help you express your understanding of basic economic concepts such as scarcity, opportunity cost, demand and supply. Unlike simple short-answer questions, an essay requires you to build a coherent argument. You need to define key terms, explain relationships, and sometimes evaluate different viewpoints. This process develops critical thinking skills that are essential for later study.
七年级经济论文写作旨在帮助你表达对稀缺性、机会成本、需求与供给等基本经济概念的理解。与简短回答题不同，论文要求你构建连贯的论证。你需要定义关键术语、解释关系，有时还要评估不同观点。这一过程能培养日后学习所必需的批判性思维能力。
Every OCR Economics essay at this level follows a similar pattern: a clear introduction, well-structured body paragraphs using the PEEL method, and a concise conclusion. You will also learn to incorporate real-world examples and, where helpful, simple diagrams or tables. Mastering this structure early will make you a confident economics writer.
此阶段的每一篇 OCR 经济论文都遵循相似的模式：清晰的引言、用 PEEL 方法构建的主体段落，以及简洁的结论。你还将学习运用现实案例，并在适当情况下使用简单图表或表格。尽早掌握这一结构将使你成为一名自信的经济学写作者。
2. Understanding the Command Words | 理解指令词
Command words tell you exactly what the examiner expects. In Year 7 OCR Economics, the most common command words are ‘explain’, ‘describe’, ‘discuss’, and ‘evaluate’. ‘Explain’ means you must give reasons and show chains of reasoning, not just state facts. For example, ‘Explain why demand increases’ requires you to link a cause, such as rising income, to the effect on quantity demanded.
指令词能准确告诉你考官期望什么。在七年级 OCR 经济中，最常见的指令词是“解释”（explain）、“描述”（describe）、“讨论”（discuss）和“评估”（evaluate）。“解释”意味着你必须给出理由并展示推理链条，而非仅仅陈述事实。例如，“解释需求为何增加”要求你将原因（如收入上升）与对需求量的影响联系起来。
‘Describe’ requires you to give a detailed account of a concept or trend, often without the need for deep analysis. ‘Discuss’ asks you to present both sides of an issue, and ‘evaluate’ goes further by weighing up arguments and coming to a reasoned judgement. Always underline the command word in the exam question so your essay stays on track.
“描述”要求你详细说明某个概念或趋势，通常无需深入分析。“讨论”要求你呈现问题的两个方面，而“评估”则更进一步，需要权衡论点并得出有理有据的判断。务必在审题时圈出指令词，以便你的论文始终切题。
3. The PEEL Paragraph Structure | PEEL 段落结构
PEEL stands for Point, Evidence, Explanation, and Link. It is the most effective way to structure a body paragraph in economics. First, state your Point clearly in one sentence. For instance, ‘An increase in the price of a substitute good raises demand for the original product.’ This gives your paragraph a clear focus.
PEEL 代表观点（Point）、证据（Evidence）、解释（Explanation）和连接（Link）。这是经济学论文中最有效的段落结构方法。首先，用一句话清晰地陈述你的 观点。例如，“替代品价格上涨会提高对原产品的需求。” 这使你的段落有了明确的中心。
Next, provide Evidence. This could be a real-world example, a data reference, or a simple diagram. In Year 7, a well-chosen example, such as how a rise in the price of butter might increase demand for margarine, works well. Then, unfold the Explanation. Use a chain of reasoning: ‘Because butter becomes more expensive, consumers look for cheaper alternatives. As a result, they switch to margarine, shifting its demand curve to the right.’
接下来，提供 证据。这可以是现实案例、数据引用或简单图表。在七年级，一个恰当的例子，如黄油价格上涨如何导致人造黄油需求增加，效果就很好。然后，展开 解释。使用推理链：“由于黄油变贵，消费者寻找更便宜的替代品。因此，他们转向人造黄油，致使其需求曲线右移。”
Finally, Link back to the question or forward to the next paragraph. You might write, ‘This shows how substitute goods influence market demand, a key factor in price determination.’ This ties everything together and keeps your essay cohesive.
最后，连接回题目或引出下一段。你可以写：“这表明替代品如何影响市场需求，这是价格决定的一个关键因素。” 这样就把所有内容串联起来，保持论文的连贯性。
4. Crafting a Strong Introduction | 撰写有力的引言
A strong introduction does three things: it defines the key economic term, sets out the scope of the essay, and presents your thesis or main argument. For example, if the question is ‘Explain why scarcity forces choices,’ you might start by defining scarcity: ‘Scarcity is the basic economic problem that arises because finite resources cannot satisfy unlimited human wants.’
一篇有力的引言需要做到三点：定义关键经济术语、设定论文范围并提出你的中心论点。例如，若题目是“解释为何稀缺性迫使人们做出选择”，你可以先定义稀缺性：“稀缺性是由有限资源无法满足无限人类欲望而产生的基本经济问题。”
Then, outline the structure: ‘This essay will examine how scarcity affects individuals, firms, and governments, using examples such as household budgeting and public spending.’ Finally, state your overall argument: ‘Ultimately, scarcity necessitates trade-offs at every level of society.’ Keep the introduction concise — three to four sentences are enough.
接着，概括结构：“本文将运用家庭预算与公共支出等例子，考察稀缺性如何影响个人、企业和政府。”最后，陈述你的总体论点：“最终，稀缺性迫使社会各层面做出权衡。” 引言应当简洁——三到四句话足矣。
5. Developing Explanation Paragraphs with Chains of Reasoning | 运用推理链展开解释段落
Chains of reasoning are the backbone of a high-quality economics essay. Instead of jumping from cause to effect, you must show the logical steps in between. Key connective phrases include ‘this means that’, ‘as a result’, ‘consequently’, and ‘therefore’. Practice building these chains until they become second nature.
推理链是高质量经济论文的基石。你不能直接从原因跳到结果，而必须展示其间的逻辑步骤。关键的连接短语包括“这意味着”、“因此”、“结果”、“故而”。多加练习，使推理链成为你的第二本能。
For instance, consider the question ‘Explain how a minimum price affects a market.’ A weak answer says: ‘A minimum price causes excess supply.’ A strong, chain-of-reasoning answer says: ‘A minimum price above equilibrium raises the legal price floor. Producers are willing to supply more because the higher price promises greater profit, but consumers buy less because the good is more expensive. This creates a situation where quantity supplied exceeds quantity demanded, leading to a surplus.’ Notice how each step is connected.
例如，思考“解释最低价格如何影响市场” 这道题。薄弱的回答是：“最低价格导致供给过剩。” 而基于推理链的强力回答是：“高于均衡价格的最低限价抬高了法定价格底线。由于高价意味着更高利润，生产者愿意供给更多；但由于商品更贵，消费者购买减少。这造成供给量大于需求量的局面，从而产生过剩。” 注意每一个步骤如何环环相扣。
When writing your paragraphs, always ask yourself ‘why?’ after each statement. If you cannot answer ‘why?’ with a clear economic reason, your chain is broken and needs more development.
在撰写段落时，每下一个结论后都问自己“为什么？”。如果你无法用明确的经济原因回答“为什么？”，那么你的推理链就断裂了，需要进一步完善。
6. Using Real-World Examples and Diagrams | 使用现实案例和图表
Examiners value real-world application. Even at Year 7 level, mentioning a relevant example shows you can apply theory to context. Examples could be drawn from news headlines, your own experience as a consumer, or simple case studies discussed in class. Always explain how the example supports your point, rather than just dropping it in.
考官看重对现实世界的应用。即使在七年级的水平，提及一个相关例子也能表明你能够将理论应用于实际。案例可以来自新闻头条、你作为消费者的自身经验，或课堂上讨论的简单案例研究。切记要解释该例子如何支撑你的观点，而不只是生硬地插入。
Diagrams are also powerful. A simple demand and supply diagram or a table showing a demand schedule can strengthen your explanation significantly. Since OCR encourages visual representation of economic ideas, you can draw a quick sketch in your answer booklet and label it clearly. In digital essays, you might describe the diagram or present a table. Below is an example of a simple demand schedule:
图表同样具有说服力。一个简单的供需图或展示需求表的表格可以显著增强你的解释。OCR 鼓励用视觉方式呈现经济思想，因此你可以在答题纸上快速绘制草图并清晰标注。在电子版论文中，你可以描述图表或呈现表格。以下是一个简单需求表的例子：
| Price (£ per unit) | Quantity Demanded |
|---|---|
| 1 | 100 |
| 2 | 80 |
| 3 | 60 |
| 4 | 40 |
The table shows the law of demand: as the price falls, consumers demand more of the good. This visual evidence makes your argument more convincing.
该表格体现了需求定律：随着价格下降，消费者对该商品的需求量增加。这一视觉证据让你的论点更具说服力。
7. The Art of Evaluation | 评估的艺术
Evaluation is what turns a good essay into an excellent one. It means looking beyond the initial explanation and considering different perspectives, long-term versus short-term effects, and the magnitude of change. Even Year 7 essays can include a short evaluation at the end of a paragraph or in a dedicated evaluation section.
评估是将一篇好论文提升为优秀论文的关键。它意味着超越初步解释，去考虑不同视角、长期与短期效应、影响的大小等。即便是七年级论文，也可以在段落末尾或专门的评估部分加入简短评估。
Use evaluative phrases such as ‘however, this depends on…’, ‘in the long run, the effect may be different’, or ‘the extent of the impact hinges on…’. For example, after explaining how a rise in income increases demand for normal goods, you might evaluate: ‘However, for inferior goods like supermarket own-brand products, a rise in income might actually reduce demand, as consumers switch to premium brands. Therefore, the overall effect on a market depends on the type of good.’ This shows deeper thinking.
使用评估性短语，例如“然而，这取决于……”、“从长期来看，效果可能不同”、“影响的程度取决于……”。比如，在解释收入增加如何提高正常商品需求后，你可以评估道：“然而，对于像超市自有品牌这样的低档商品，收入增加反而可能减少需求，因为消费者会转向高端品牌。因此，对某个市场的总体影响取决于商品的类型。” 这体现出了更深层的思考。
Always try to go beyond a one-sided view. Even if the question only asks you to explain, a short evaluative comment can demonstrate higher-order skills and earn you top marks.
始终力求超越单方面的观点。即使题目只要求解释，一句简短的评估性评论也能展现高阶思维，助你拿到最高分。
8. Structuring a Conclusion | 构建结论
Your conclusion should summarise the main arguments without introducing new information. Restate the central economic idea and briefly recap how your body paragraphs supported it. A strong conclusion leaves the reader with a clear sense of closure.
你的结论应概括主要论点，而不能引入新的信息。重申核心经济思想，并简要回顾你的主体段落如何支撑它。一个好的结论能给读者留下清晰的收尾感。
For instance, in an essay about scarcity and choice, you might conclude: ‘In conclusion, scarcity is the fundamental driver of all economic decision-making. Individuals face opportunity costs in daily purchases, firms must decide how to allocate limited resources, and governments choose between competing public projects. Therefore, no society can escape the need to make choices.’ This echoes your introduction and reinforces your thesis.
例如，在一篇关于稀缺性与选择的论文中，你可以这样结尾：“总之，稀缺性是所有经济决策的根本驱动力。个人在日常购买中面临机会成本，企业必须决定如何分配有限资源，政府则要在相互竞争的项目中做出选择。因此，任何社会都无法逃脱选择的必要性。” 这呼应了你的引言并强化了你的论点。
Avoid ending with a vague statement like ‘there are many factors to consider.’ Instead, be definitive and tie your argument back to the question. A well-written conclusion can be the perfect finishing touch.
避免以“需要考虑的因素有很多”这类模糊的表述结尾。相反，要态度明确，并将论点与问题紧扣。一篇出色的结论可以成为画龙点睛之笔。
9. Model Essay: Scarcity and Choice | 范文：稀缺性与选择
Essay question: Explain why scarcity forces individuals and governments to make choices. Use examples to support your answer. (15 marks) / 论文题目：解释为什么稀缺性迫使个人和政府做出选择。请举例说明。（15 分）
Below is a model answer broken into logical paragraphs. Each paragraph is given in English first, followed by its Chinese translation. / 以下是一篇按照逻辑段落拆分的范文。每个段落先提供英文，再提供中文翻译。
Introduction / 引言
Scarcity is the fundamental economic problem that arises because human wants are unlimited, but the resources available to satisfy them are finite. This means that all decision-makers — individuals, firms, and governments — must constantly make choices about how to use their limited resources. This essay will explain how scarcity forces these choices, using the example of a student’s pocket money and a local council’s budget.
稀缺性是基本的经济问题，它源于人类欲望的无限性与资源的有限性。这意味着所有决策者——个人、企业和政府——都必须不断就如何使用有限资源做出选择。本文将运用学生零花钱和地方议会预算的例子，解释稀缺性如何迫使这些选择发生。
Body Paragraph 1 – Individual choice / 主体段 1 —— 个人选择
For individuals, scarcity means they cannot have everything they desire. A student with a limited weekly pocket money budget faces a direct constraint. Suppose a student has £10 per week and wants to buy both a cinema ticket (£8) and a takeaway meal (£7). Because the total cost (£15) exceeds the available budget, the student must choose one or the other. The next-best alternative forgone is the opportunity cost. If the student chooses the cinema, the opportunity cost is the enjoyment of the takeaway meal. This illustrates how scarcity forces individuals to prioritise and make trade-offs.
对于个人而言，稀缺性意味着他们无法拥有所有想要的东西。一个每周零花钱有限的学生就面临着直接约束。假设一名学生每周有 10 英镑，既想买一张 8 英镑的电影票，又想买一份 7 英镑的外卖餐。由于总花销（15 英镑）超出了可用预算，该学生必须选择其中一个。所放弃的次优选择就是机会成本。如果学生选择了电影，其机会成本便是享受外卖餐的快乐。这阐明了稀缺性如何迫使个人进行优先排序和权衡取舍。
Body Paragraph 2 – Government choice / 主体段 2 —— 政府选择
Governments also face scarcity, because tax revenue is limited. A local council might have £5 million to allocate between building a new leisure centre and improving road infrastructure. If it chooses the leisure centre, roads may remain congested. The opportunity cost is the benefit from fewer potholes and smoother traffic flow. However, in the long run, a leisure centre might improve public health and reduce NHS costs. This shows that government choices involve evaluating both short-term sacrifices and long-term benefits, all driven by the scarcity of public funds.
政府同样面临稀缺，因为税收收入是有限的。一个地方议会可能有 500 万英镑可用于建造新休闲中心或改善道路基础设施。如果它选择了休闲中心，道路可能依然拥堵。其机会成本便是减少坑洞和获得更顺畅交通的好处。然而，从长远来看，休闲中心可能改善公共健康、降低国民保健服务开支。这表明政府选择需要兼顾短期牺牲与长期收益，而这皆由公共资金的稀缺性所驱动。
Conclusion / 结论
In conclusion, scarcity affects all levels of society. Individuals must make daily spending choices with limited income, and governments must budget with finite tax revenues. Every choice involves an opportunity cost, which is the value of the next-best alternative. Therefore, scarcity is inescapable, and understanding it is the first step to making better economic decisions.
总之，稀缺性影响着社会的所有层面。个人必须在有限的收入下做出日常消费选择，政府则必须用有限的税收进行预算。每一个选择都涉及机会成本，即次优选择的价值。因此，稀缺性不可避免，而理解它是做出更优经济决策的第一步。
10. Model Essay: Demand and Supply | 范文：需求与供给
Essay question: Using a table or diagram, explain how the equilibrium price is determined in a market for a product such as bottled water. (15 marks) / 论文题目：运用表格或图表，解释瓶装水这类产品的市场均衡价格是如何决定的。（15 分）
Introduction / 引言
The price of bottled water, like any other good, is not set by producers alone. It is determined by the interaction of demand and supply. Demand reflects how much consumers are willing and able to buy at different prices, while supply reflects how much producers are willing to sell. The equilibrium price is found where quantity demanded equals quantity supplied. This essay will use a demand and supply table to explain this process.
瓶装水的价格，如同其他任何商品一样，并非由生产者单方面决定。它由需求与供给的相互作用决定。需求反映了消费者在不同价格下愿意并能够购买的数量，而供给反映生产者愿意销售的数量。均衡价格出现在需求量等于供给量之处。本文将运用供需表解释这一过程。
Demand and supply schedule / 需求与供给表
| Price (£ per bottle) | Quantity Demanded (bottles per day) | Quantity Supplied (bottles per day) |
|---|---|---|
| 0.50 | 200 | 50 |
| 1.00 | 150 | 100 |
| 1.50 | 100 | 150 |
| 2.00 | 60 |
