在七年级 WJEC 经济课程中，写出条理清晰、结构严谨的论文是一项关键技能。它能帮助你展示对稀缺性、选择和机会成本等基本经济概念的理解。本文提供一个完整的写作框架、一篇逐步解析的范文，以及针对 11–12 岁学生的实用建议。无论你是在准备单元测验还是课堂评估，掌握这一结构都将提升你的信心和分数。
1. Why Essay Writing Matters in Economics | 为什么论文写作在经济学中很重要
In Economics, essays are not just about remembering facts. They test whether you can explain ideas, link concepts together, and use examples to support your points. For Year 7 students, this often means showing how scarcity forces people to make choices, or why a shop might raise its prices.
在经济学中，论文不仅仅是记住事实。它考察你是否能解释概念、将不同观点联系起来，并用例子佐证你的论点。对七年级学生来说，这通常意味着解释稀缺性如何迫使人们做出选择，或者为什么一家商店会提高价格。
Good essay skills help you in all your subjects. They teach you to answer the question directly, organise your thinking, and write in a logical order. Even a short paragraph answer follows the same rules as a longer essay.
良好的论文写作技巧对各个学科都有帮助。它教你直接回答问题、整理思路，并按逻辑顺序写作。即使是一小段简答题，也遵循与长篇论文相同的规则。
In WJEC assessments, you may be asked to write a few paragraphs or a short essay. Your examiner looks for clear definitions, a chain of reasoning, relevant examples, and a short conclusion that links back to the question.
在 WJEC 考试中，你可能会被要求写几段话或一篇短文。考官看重清晰的定义、推理链条、相关的实例，以及一个能回扣题目的简短结论。
2. Understanding the Essay Question | 理解论文题目
Before you start writing, always read the question at least twice. Underline or circle the ‘command words’ – these tell you exactly what to do. Common command words in Year 7 Economics include ‘explain’, ‘describe’, ‘discuss’, and ‘give two reasons’.
动笔之前，一定要把题目至少读两遍。在“指令词”下面画线或画圈，这些词会明确告诉你需要做什么。七年级经济中常见的指令词包括“解释”、“描述”、“讨论”和“给出两个理由”。
For example, if the question says “Explain why scarcity leads to choice,” you must give reasons and show a clear link, not just write a definition. If it says “Describe two ways the government might use money from taxes,” you need to describe, not explain causes.
例如，如果题目是“解释为什么稀缺性会导致选择”，你必须给出理由并展示清晰的联系，而不只是写一个定义。如果题目是“描述政府使用税收拨款的两种方式”，你只需描述，不需要解释原因。
Take 30 seconds to rewrite the question in your own words mentally. This helps you check you have understood it correctly.
花 30 秒在心里用自己的话重述题目。这有助于你检查自己是否正确理解了题意。
3. Essential Structure: Introduction | 基本结构：引言
Every essay needs a short introduction. For Year 7, aim for two or three sentences. Your introduction should define the key economic term from the question and state what your essay will do.
每篇论文都需要一个简短的引言。七年级学生写两到三句即可。你的引言应该定义题目中的关键经济术语，并表明你的论文将要写什么。
A simple formula is: (1) Define the main term, (2) Briefly explain why it matters, and (3) Signpost your main point. For instance, for a question on opportunity cost, you could write: “Opportunity cost is the next best alternative given up when a choice is made. It exists because resources are scarce.”
一个简单的公式是：（1）定义主要术语，（2）简要解释为什么它很重要，（3）预告你的主要论点。例如，一个关于机会成本的题目，你可以这样写：“机会成本是做出选择时所放弃的次优替代方案。它之所以存在，是因为资源是稀缺的。”
Never start your essay by repeating the question. Instead, use the keywords naturally. This shows the examiner that you understand the concept from the very beginning.
千万不要通过复述题目来开头。相反，要自然地使用关键词。这能让考官从一开始就觉得你理解了这个概念。
4. Developing the Main Body with PEEL | 使用 PEEL 段落发展主体
The main body of your essay should be built using the PEEL method. PEEL stands for Point, Evidence, Explanation, and Link. This structure keeps your paragraphs focused and easy to follow.
论文的主体部分应使用 PEEL 方法来构建。PEEL 分别代表 Point（论点）、Evidence（证据）、Explanation（解释）和 Link（扣题串联）。这个结构能让你的段落重点突出、易于理解。
- Point: Start with a clear sentence that answers part of the question. Example: “One reason scarcity leads to choice is that people have limited income.”
- 论点：以一个清晰回答部分题目的句子开头。例如：“稀缺性导致选择的一个原因是，人们的收入是有限的。”
- Evidence: Add a real-life or textbook example. For Year 7, a simple market example works well, such as a student choosing between a cinema ticket and a new notebook with a fixed amount of pocket money.
- 证据：添加一个现实生活或课本例子。对七年级来说，一个简单的市场例子就很好，比如一个学生用固定数额的零花钱在电影票和新的笔记本之间做选择。
- Explanation: Explain how your evidence proves the point. Use the word “because” to develop a chain of reasoning: “Because money is limited, the student cannot have both, so they must choose.”
- 解释：解释你的证据如何证明论点。使用“因为”一词展开推理链条：“因为钱是有限的，学生无法两样都买，所以必须做出选择。”
- Link: End the paragraph by linking back to the question or introducing the next idea. “This shows that limited resources force individuals to make choices every day.”
- 扣题串联：段落结尾时回扣题目或引出下一个观点。“这表明有限的资源迫使人们每天都要做选择。”
Using one or two strong PEEL paragraphs in the main body will make your essay much stronger than just writing everything you know in one block.
在主体中使用一到两个扎实的 PEEL 段落，会比把你知道的一切都堆在一个大段落里让论文更有力。
5. Applying Economic Vocabulary | 运用经济学术语
In WJEC Economics, using precise vocabulary shows a deeper understanding. Try to include key terms such as scarce resources, choice, opportunity cost, needs, wants, trade-off, and allocate. But be careful – only use a term if you are confident in its meaning.
在 WJEC 经济学中，使用精确的词汇能展现出更深的理解。尽量使用关键术语，如稀缺资源、选择、机会成本、需要、想要、权衡和分配。但要注意，只有在确信词义时才使用它。
You can create a small glossary at home to practise. Write the term on one side of a flashcard and its definition plus an example on the other. Before writing any essay, review five to six relevant terms and try to use at least three of them naturally in your answer.
你可以在家制作一个小型词汇表来练习。将术语写在抽认卡的一面，背面写上定义和一个例子。在写论文之前，复习五到六个相关术语，并尽量在答案中自然地使用其中至少三个。
For example, instead of writing “People cannot have everything they want,” try “Because resources are scarce, people face trade-offs and must consider opportunity cost when making decisions.” This sentence uses three economic terms correctly.
例如，与其写“人们不能拥有他们想要的一切”，不如写成“因为资源是稀缺的，人们在决策时会面临权衡，必须考虑机会成本。”这个句子正确使用了三个经济术语。
6. Using Real-Life Examples | 使用真实例子
Examples bring your essay to life. For Year 7 WJEC, examples do not need to be complicated. A simple scenario about a school canteen, a family supermarket trip, or pocket money choices works perfectly.
例子能让你的论文生动起来。对七年级 WJEC 而言，例子不需要复杂。一个关于学校食堂、家庭超市购物或零花钱选择的简单情景就非常合适。
Make your examples specific. Instead of saying “a person buying a chocolate bar,” you could say “a Year 7 student with £2 to spend at break time choosing between a bottle of water and a fruit smoothie.” The more realistic the example, the easier it is to explain the economic ideas.
让你的例子具体化。与其说“一个人买了一根巧克力棒”，不如说“一个七年级学生在课间有 2 英镑可以花，在一瓶水和一杯水果奶昔之间做选择”。例子越贴近现实，解释经济学概念就越容易。
A strong example helps you demonstrate both the concept and its real-world impact. It also gives you something concrete to analyse, which is exactly what an economic essay requires.
一个好的例子能让你同时展示概念及其在现实世界中的影响。它也为你提供了具体的分析对象，而这正是经济论文所需要的。
7. Model Essay: Scarcity and Choice | 范文：稀缺性与选择
Below is a full model answer to a typical Year 7 WJEC question. The question is: “Explain why scarcity means that individuals and businesses have to make choices. Use examples in your answer.”
以下是一篇针对典型七年级 WJEC 题目的完整范文。题目是：“解释为什么稀缺性意味着个人和企业必须做出选择。在答案中使用例子。”
Model Answer
范文
Scarcity is the basic economic problem that there are limited resources but unlimited wants. It affects everyone because we cannot have everything we desire. This means individuals and businesses must make choices, and every choice involves an opportunity cost.
稀缺性是基本的经济问题，指资源有限而欲望无穷。它影响到每个人，因为我们无法拥有所渴望的一切。这意味着个人和企业必须做出选择，而每一个选择都涉及机会成本。
Individuals face scarcity because they have limited income. For example, a teenager with £10 pocket money per week wants both a new mobile game costing £6 and a cinema ticket costing £8. She cannot afford both, so she must choose. If she chooses the game, her opportunity cost is the cinema experience she gives up. This shows how limited money forces her to make a decision based on what she values more.
个人面临稀缺是因为收入有限。例如，一个每周有 10 英镑零花钱的青少年，既想要一个 6 英镑的手机游戏，又想买一张 8 英镑的电影票。她无法同时支付两者，所以必须选择。如果她选了游戏，她的机会成本就是所放弃的电影体验。这表明有限的金钱迫使她依据自己更看重什么来做出决定。
Businesses also face scarcity because they operate with limited land, labour, capital, and time. A local bakery, for instance, has only three workers and four hours in the morning. It can use these resources to produce either 200 loaves of bread or 500 cupcakes, but not both fully. The bakery must choose based on customer demand and profit. If it chooses bread, the cupcakes it could have made represent its opportunity cost. This trade-off illustrates why scarcity forces businesses to prioritise.
企业同样面临稀缺，因为它们经营时所用的土地、劳动力、资本和时间都是有限的。例如，本地一家面包店只有三名员工和早上的四个小时。它可以用这些资源生产 200 条面包或者 500 个纸杯蛋糕，但无法两者都足量生产。面包店必须根据顾客需求和利润做出选择。如果它选择生产面包，那么它本可以制作的纸杯蛋糕就构成了其机会成本。这种权衡说明了为什么稀缺性能迫使企业排出优先次序。
In conclusion, scarcity exists because resources are limited in relation to people’s wants. This means choices are unavoidable for both individuals and firms. When a choice is made, the next best alternative that is sacrificed is the opportunity cost. Understanding this helps us see why economics is about making careful decisions.
总之，稀缺性的存在是因为相对于人们的欲望，资源是有限的。这意味着选择对个人和企业都是不可避免的。当做出一个选择时，被牺牲的次优替代方案就是机会成本。理解这一点有助于我们明白为什么经济学关注的是如何做出审慎的决策。
8. Breaking Down the Model Answer | 解析范文
Let’s analyse how this essay follows the recommended framework. The first paragraph acts as the introduction: it defines scarcity and directly links it to choice and opportunity cost. This immediately shows the examiner that the student knows the key concept.
我们来分析这篇范文是如何遵循推荐框架的。第一段充当引言：它定义了稀缺性，并将其与选择和机会成本直接联系起来。这立刻向考官表明学生掌握了关键概念。
The second paragraph is a clear PEEL about individuals. The point is that limited income forces choice. The evidence is the specific example of the teenager with £10, a game, and a cinema ticket. The explanation uses “because” and “if… then” reasoning, and the link ties back to scarcity and values.
第二段是一个清晰的关于个人的 PEEL 段落。论点是收入有限迫使选择。证据是那个具体例子：有 10 英镑的青少年、游戏和电影票。解释部分使用了“因为”和“如果……那么……”的推理，最后的扣题将内容与稀缺性和价值观联系起来。
The third paragraph mirrors the first but shifts to businesses, demonstrating the ability to apply the same concept to different economic agents. The bakery example shows factors of production in a simple way. Notice that the paragraph does not just describe the bakery – it explicitly uses the term ‘opportunity cost’ and ‘trade-off’.
第三段与第二段结构相似，但转向了企业，展示出将同一概念应用于不同经济主体的能力。面包店的例子以简单的方式呈现了生产要素。请注意，该段落不只是描述面包店，而是明确使用了“机会成本”和“权衡”这两个术语。
The conclusion summarises the argument without introducing new information. It rephrases the link between scarcity, choice, and opportunity cost, which is exactly what the question asked for. This demonstrates a complete and well-rounded answer.
结论总结了论点，但没有引入新信息。它重新阐述了稀缺性、选择与机会成本之间的联系，这正是题目所要求的。这展示了一个完整而全面的答案。
9. Marking Criteria for WJEC Year 7 | WJEC 七年级评分标准
In Year 7, your teacher uses a simplified version of WJEC mark schemes. Typically, marks are given for knowledge and understanding, application, and analysis. Even a short essay can be marked out of 8 or 12 marks.
七年级时，老师会使用简化的 WJEC 评分方案。通常，分数会根据知识与理解、应用和分析来给分。即使一篇短文也可能按 8 分或 12 分来评。
| Level | Criteria | What it looks like in Year 7 |
|---|---|---|
| 1 (1–2 marks) | Basic knowledge | You define one term or give a simple isolated fact, e.g. ‘Scarcity means not enough resources.’ |
| 2 (3–4 marks) | Knowledge with some application | You define scarcity and give a relevant example, but the link is not fully explained. |
| 3 (5–6 marks) | Good understanding and clear application | You define key terms, use a concrete example, and show a logical chain of reasoning with ‘because’. |
| 4 (7–8 marks) | Precise analysis and economic vocabulary | Your essay includes accurate terminology, two well-explained examples, and a conclusion that consistently links back to the question. |
| 等级 | 标准 | 七年级的表现形式 |
|---|---|---|
| 1 (1–2 分) | 基础知识 | 你定义了一个术语，或给出了一个简单孤立的事实，如“稀缺性意味着资源不足”。 |
| 2 (3–4 分) | 有知识且有一定应用 | 你定义了稀缺性并给出了一个相关例子，但没有充分解释其中的联系。 |
| 3 (5–6 分) | 理解良好且应用清晰 | 你定义了关键术语，使用了具体例子，并用“因为”展示了清晰的逻辑推理链条。 |
| 4 (7–8 分) | 分析精准且运用经济词汇 | 你的论文包含准确的术语、两个阐释充分的例子，以及一个始终回扣题目的结论。 |
Knowing this simple scale helps you aim for Level 3 or 4. It means you must do more than just define scarcity – you must show why it matters and provide a logically connected example.
了解这个简单的评分等级有助于你力争达到 3 或 4 级。这意味着你不仅要会定义稀缺性，还要说明它为什么重要，并给出逻辑相关的例子。
10. Common Mistakes to Avoid | 常见错误避免
Many Year 7 students lose marks for the same reasons. Avoid these common errors to protect your grade.
许多七年级学生因相同的原因而失分。避开这些常见错误，能保护你的分数。
First, never write everything you know without linking it to the question. If the question is about choices, do not spend a whole paragraph explaining needs and wants unless it directly supports your point.
第一，不要把你所知道的一切都写上去，却不联系题目。如果题目是关于“选择”，就别花一整段解释“需要与想要”，除非它能直接支持你的论点。
Second, do not forget the example. An essay that defines scarcity but provides no real-life scenario will stall at Level 2. Always ask yourself: ‘Can I give a short, clear example about a person, a shop, or a school?’
第二，不要忘记例子。一篇只定义了稀缺性但没有提供现实情景的论文会止步于 2 级。永远问自己：“我能否举出一个关于个人、商店或学校的简短清晰的例子？”
Third, try not to use very general statements like ‘This is important for the economy.’ Be precise: ‘This is important because it shows how limited resources affect everyday decisions for households.’ Precision earns higher marks.
第三，尽量避免使用非常笼统的表述，如“这对经济很重要”。要具体：“这一点很重要，因为它展示了有限资源如何影响家庭的日常决策。”准确的表述能赢得更高的分数。
Finally, leave two minutes to read your essay and check for missing words or unclear sentences. Even a quick review can catch simple mistakes that would otherwise cost you marks.
最后，留两分钟通读你的论文，检查是否有漏词或表意不清的句子。即使快速检查也能发现一些本可能导致扣分的简单错误。
11. Practice Exercise and Planning | 练习与计划
Now it is your turn. Try planning an answer to this question: “Explain why businesses need to consider opportunity cost when deciding what to produce. Use an example.” Follow the steps below.
现在轮到你了。尝试为以下题目规划一个答案：“解释为什么企业在决定生产什么时必须考虑机会成本。请使用一个例子。”按照以下步骤操作。
Step 1: Underline the command word (‘explain’) and key terms (‘businesses’, ‘opportunity cost’, ‘deciding what to produce’).
第 1 步：在指令词（“解释”）和关键术语（“企业”、“机会成本”、“决定生产什么”）下画线。
Step 2: In one sentence, write a definition of opportunity cost that fits this question.
第 2 步：用一句话写出一个适合本题的机会成本定义。
Step 3: Draft two PEEL points – one about a factory choosing between two products, and one about a farm choosing between crops. Make sure each point includes a specific example and uses ‘because’.
第 3 步：起草两个 PEEL 论点——一个关于工厂在两种产品之间选择，另一个关于农场在两种作物之间选择。确保每个论点包含具体例子并使用“因为”。
Step 4: Write a short conclusion that links opportunity cost to the idea of limited resources and choice, without repeating the introduction word for word.
第 4 步：写一个简短的结论，将机会成本与资源有限和选择的概念联系起来，但不要逐字重复引言。
Practising this planning process for three different questions will make the essay structure feel automatic in the test.
用三道不同的题目练习这一规划过程，考试时论文结构就会变得自然而然。
12. Final Tips for Essay Confidence | 提升论文信心的最后提示
Remember, a well-structured short essay is always better than a long, messy one. Focus on quality, not length. Your teacher wants to see that you think like an economist by linking concepts to real situations.
记住，一篇结构清晰的短文永远比一篇又长又乱的文章要好。关注质量而非长度。你的老师希望看到你能像经济学家一样思考，将概念与现实情景联系起来。
Before the assessment, create a checklist: Did I define the key term? Did I use at least one example? Did I explain with ‘because’? Did I link back to the question in my conclusion? If you can tick all these, you are on the right track.
评估前，制作一个检查清单：我定义关键术语了吗？我至少使用了一个例子吗？我用“因为”来解释了吗？我在结论中回扣题目了吗？如果你能全部打勾，那就说明你走在对的路上了。
Writing is a skill that improves with practice. Use the framework and model answer in this article as a guide, and keep building your confidence one paragraph at a time.
写作是一项可以通过练习来提高的技能。把本文中的框架和范文作为指南，一段一段地逐步建立你的信心。
