📚 Essay Writing Framework for Year 7 Cambridge Economics | 剑桥七年级经济学论文写作框架与范文
Writing a clear, well-structured essay is an essential skill in Cambridge Year 7 Economics. This guide provides a step-by-step framework to help you plan, structure and write effective economics essays, from understanding the question to crafting a strong conclusion. We will also look at a model essay on scarcity and choice to show how the framework works in practice.
撰写清晰、结构良好的论文是剑桥七年级经济学课程中的关键技能。本指南将为你提供一个循序渐进的框架，帮助你规划、组织并写出有效的经济学论文，从理解题目到写出有力的结论。我们还会通过一篇关于稀缺与选择的范文来展示如何实际运用这一框架。
1. Understanding the Essay Question | 理解题目要求
Before you start writing, read the question carefully and circle the command words. Common command words in Year 7 include ‘describe’, ‘explain’ and sometimes ‘discuss’. ‘Describe’ asks you to give factual details, while ‘explain’ requires you to say why or how something happens. If you see a term you do not know, look it up in your textbook or class notes.
在动笔之前，仔细阅读题目并圈出指令词。七年级常见的指令词包括“描述”、“解释”以及有时出现的“讨论”。“描述”要求你给出事实细节，而“解释”则需要你说明某件事为什么会发生或如何发生。如果你碰到不认识的术语，请到课本或课堂笔记里进行查阅。
Break the question into parts and underline the key economic concepts. For example, a question such as ‘Explain why scarcity forces people to make choices’ has two main parts: defining scarcity and explaining the link to choices. Make sure your answer covers all parts of the question.
把题目拆分成几个部分，并在关键的经济学概念下划线。例如，“解释为什么稀缺性迫使人们做出选择”这个题目包含两个主要部分：定义稀缺性并解释它与选择之间的联系。确保你的答案涵盖题目的所有方面。
2. Structuring Your Introduction | 引言结构
A strong introduction does three things. First, it defines the most important economic term from the question. Second, it gives a short answer to the question – your main argument. Third, it outlines the structure of your essay in one or two sentences. Keep it straightforward and avoid long background stories.
一个有力的引言需要完成三件事。第一，定义题目中最重要的经济学术语。第二，对问题给出一个简短回答——就是你的主要论点。第三，用一两句话概括你论文的结构。保持直截了当，避免冗长的背景叙述。
For example, an introduction for a question on opportunity cost might begin with: ‘Opportunity cost is the next best alternative given up when a choice is made. In this essay, I will explain why opportunity cost matters for consumers, producers and the government.’
例如，一个关于机会成本题目的引言可以这样开头：“机会成本是做出一个选择时所放弃的次优替代选项。在本文中，我将解释为什么机会成本对消费者、生产者和政府来说都很重要。”
3. Writing Clear Definitions | 清晰定义
Economic definitions must be precise and complete. Do not simply repeat the word from your textbook in the definition. For instance, define ‘scarcity’ as: ‘the basic economic problem that arises because wants are unlimited but resources are limited.’ Avoid vague phrases like ‘scarcity is when there is not enough of something’ – that is too general and misses the link between wants and resources.
经济学术语的定义必须准确且完整。不要在定义中简单地重复课本上的词语。比如，把“稀缺性”定义为：“由于人的欲望无限而资源有限所产生的基本经济问题”。避免使用“稀缺性就是某种东西不够了”这样模糊的表述——那过于笼统，并且遗漏了欲望与资源之间的联系。
Whenever you introduce a new economic term, such as ‘needs’, ‘wants’, ‘goods’ or ‘services’, give a short definition before using it in your argument. This shows the examiner that you understand the vocabulary of economics.
每当你引入一个新的经济学术语，比如“需要”、“欲望”、“商品”或“服务”，都要在将其用于论证之前给出简短的定义。这向考官展示你掌握了经济学的词汇。
4. Using Economic Terminology | 运用经济术语
Using the correct economic words makes your essay more precise and convincing. For Year 7, some essential terms include: ‘scarcity’, ‘choice’, ‘opportunity cost’, ‘needs’, ‘wants’, ‘factors of production’ (land, labour, capital, enterprise), ‘goods’, ‘services’, ‘consumer’ and ‘producer’. Learn to spell them correctly and use them naturally in your sentences.
使用正确的经济学词汇会让你的论文更加准确、有说服力。对于七年级学生来说，一些核心术语包括：“稀缺性”、“选择”、“机会成本”、“需要”、“欲望”、“生产要素”（土地、劳动力、资本、企业家才能）、“商品”、“服务”、“消费者”和“生产者”。学会正确地拼写它们，并在句子中自然地运用。
Instead of writing ‘people cannot have everything they want’, write ‘due to scarcity, people must make choices because they have unlimited wants but finite resources.’ This small change shows a higher level of understanding and uses key terminology effectively.
不要写“人们不能拥用他们想要的一切”，而要写“由于稀缺性，人们必须做出选择，因为他们的欲望是无限的而资源是有限的”。这个小小的改动体现了更高的理解水平，并有效地使用了关键术语。
5. Explaining with Examples | 举例说明
Every economic argument becomes stronger when supported by a real-world example. In Year 7, you can use simple, everyday situations. For instance, when explaining opportunity cost, you might write: ‘If a student has £10 and chooses to buy a cinema ticket instead of a book, the opportunity cost is the book they gave up.’ Such examples make abstract ideas concrete.
每一个经济学论证在得到现实例子的支撑时都会变得更有力。在七年级阶段，你可以使用简单的日常情景。例如，在解释机会成本时，你可以写道：“如果一个学生有10英镑，并选择购买一张电影票而不是一本书，那么机会成本就是他们所放弃的那本书。”这样的例子使抽象的概念变得具体。
You can also refer to local businesses, school canteen choices or pocket money decisions. The key is to link the example clearly back to the economic idea. Do not just tell a story – always explain how it illustrates the concept.
你还可以引用当地的企业、学校食堂的选择或者零花钱的决定。关键是要把例子与经济学观点清晰地联系起来。不要只讲一个故事——要始终解释这个例子如何阐述相关概念。
6. Diagrams and Simple Models | 图表与简单模型
In Year 7, you may not need complex graphs, but you can use simple tables or models to organise your ideas. A table that compares two choices and their opportunity costs can be very effective. For example, a table comparing ‘Option A: buy a pizza’ and ‘Option B: buy a sandwich’ with a column for ‘benefit given up’ helps show trade-offs.
在七年级阶段，你可能不需要复杂的图表，但你可以使用简单的表格或模型来组织你的想法。一个比较两种选择及其机会成本的表格可以非常有效。例如，一个比较“选项A：买披萨”和“选项B：买三明治”的表格，配上一栏“放弃的益处”，有助于展示权衡取舍。
| Option / 选项 | Choice / 选择 | Next best alternative given up / 放弃的次优替代项 |
|---|---|---|
| A | Pizza / 披萨 | Sandwich / 三明治 |
| B | Sandwich / 三明治 | Pizza / 披萨 |
If you are asked to draw a simple production possibilities frontier, you can sketch two goods on the axes and show that moving from one point to another involves giving up some amount of the other good. Even a hand-drawn diagram labelled clearly with a pencil is fine in an exam, as long as it is accurate.
如果题目要求你画出简单的生产可能性边界，你可以在坐标轴上标出两种商品，并展示从一点移动到另一点需要放弃一定数量的另一种商品。只要准确无误，考试中即使用铅笔画出的简图也是可以的，关键是要标注清楚。
7. Developing Arguments | 展开论证
For each main point in your essay, use the PEEL structure: Point, Explain, Example, Link. Start with a clear Point that answers the question directly. Then Explain the economic reasoning behind that point. Add an Example to illustrate it. Finally, Link the point back to the question or to the next paragraph.
针对论文中的每一个主要观点，使用PEEL结构：观点(Point)、解释(Explain)、举例(Example)、连接(Link)。以一个直接回答题目问题的清晰观点开头。然后解释该观点背后的经济学原理。再添加一个例子以作说明。最后，将这个观点连接回到题目或与下一段落相联系。
Example PEEL paragraph on scarcity: Point: Scarcity forces households to make daily choices. Explain: Because a family has limited income and unlimited wants, it cannot buy everything. It must decide which goods and services to purchase. Example: A family might choose to spend money on food rather than on a new toy, because food satisfies a basic need. Link: So scarcity directly leads to the need to prioritise spending, which is seen every day in household budgets.
关于稀缺性的PEEL段落示例：观点：稀缺性迫使家庭每天做出选择。解释：由于一个家庭的收入有限而欲望无限，它无法购买所有东西，必须决定购买哪些商品和服务。例子：一个家庭可能会选择把钱花在食物上，而不是花在购买新玩具上，因为食物满足的是基本需要。连接：因此，稀缺性直接导致了安排支出优先顺序的必要性，这在家庭日常预算中随处可见。
8. Conclusion Writing | 结论写作
Your conclusion should briefly summarise the main arguments you have made, without introducing any new information. Start by restating the core economic problem or term. Then remind the reader how your body paragraphs answered the question. End with a final sentence that reinforces the importance of the concept in real life.
你的结论应该简要总结你提出的主要论点，不要引入任何新信息。先重申核心的经济问题或术语。然后提醒读者你的主体段落是如何回答问题的。最后用一句强调该概念在现实生活中重要性的结尾句收束全文。
Make sure the conclusion directly mirrors the introduction. If your introduction said you would explore three reasons why scarcity leads to choice, then the conclusion should clearly mention those three reasons again in a synthesised way. This gives your essay a strong sense of completeness.
确保结论与引言直接呼应。如果你的引言中说你要探讨稀缺性导致选择的三个原因，那么结论就应该以综合的方式再次清楚地提到这三个原因。这会给你的论文带来强烈的完整感。
9. Common Mistakes to Avoid | 常见错误避免
One common mistake is forgetting to answer all parts of the question. Some essays only explain one side, even when the question asks for ‘discuss’ or for both advantages and disadvantages. Always check the question carefully after finishing your essay plan.
一个常见错误是忘记回答题目的所有部分。有些论文只解释了一方面，而题目却要求“讨论”或同时涉及优点与缺点。在完成论文大纲后，一定要仔细检查一遍题目。
Another mistake is writing without examples or definitions. Economic essays without concrete examples often sound too vague. Also, avoid writing a very long introduction that does not add value, and make sure your sentences are clear and not too long. Finally, always proofread for spelling and grammar.
另一个错误是写作时不提供例子或定义。没有具体例子的经济学论文往往听起来过于空泛。此外，避免写一个过于冗长却没有附加价值的引言，并确保句子清晰且不要过长。最后，一定要校对自己的拼写和语法。
10. Model Essay: Scarcity and Choice | 范文：稀缺与选择
Introduction: Scarcity is the fundamental economic problem that exists because unlimited human wants face finite resources. This essay will explain why scarcity inevitably leads to choices, and how these choices create opportunity costs for individuals, businesses and governments.
引言：稀缺性是由于无限的人类欲望面临着有限的资源而存在的基本经济问题。本文将解释为什么稀缺性不可避免地导致选择，以及这些选择如何为个人、企业和政府带来机会成本。
Scarcity means that there are not enough resources – land, labour, capital and enterprise – to produce all the goods and services that people desire. Because wants are unlimited, while resources such as time, money and raw materials are limited, no society can have everything it wants. This forces economic agents – consumers, producers and governments – to make decisions about how to allocate resources.
稀缺性意味着没有足够的资源——土地、劳动力、资本和企业家才能——来生产人们想要的所有商品和服务。由于欲望是无限的，而时间、金钱和原材料等资源是有限的，没有任何一个社会能够拥用它所想要的一切。这就迫使经济主体——消费者、生产者和政府——就如何分配资源做出决定。
When a choice is made, something must be given up. The next best alternative that is sacrificed is called the opportunity cost. For example, a student who uses her evening to study economics rather than play video games faces an opportunity cost: the enjoyment from gaming that she has to forgo. The concept of opportunity cost applies at all levels of the economy.
当做出一个选择时，就必须放弃某些东西。被牺牲掉的次优替代选项就称为机会成本。例如，一名学生利用晚上的时间学习经济学而不是玩电子游戏，她就面临着一个机会成本：即她不得不放弃的游戏乐趣。机会成本这一概念适用于经济的各个层面。
A government also faces scarcity because tax revenue is limited but public needs – such as building hospitals, schools and roads – are vast. If the government decides to spend more money on defence, the opportunity cost might be fewer funds available for education. This illustrates that every economic choice involves a trade-off between competing wants.
政府也同样面临稀缺性，因为税收收入有限，而公共需求——如修建医院、学校和道路——却是巨大的。如果政府决定在国防上投入更多资金，那么机会成本可能就是用于教育的资金减少了。这说明每一个经济选择都涉及在相互竞争的欲望之间进行权衡。
Conclusion: Scarcity is the root of all economic decision-making. Because resources are never enough to satisfy every want, individuals, firms and governments must constantly choose how to use them. Each choice carries an opportunity cost, reminding us that we can never have everything we desire. Understanding scarcity and choice helps us make better, more informed decisions in our daily lives.
结论：稀缺性是一切经济决策的根源。由于资源永远不足以满足每一种欲望，个人、企业和政府必须不断选择如何使用资源。每一个选择都带有机会成本，提醒我们不可能拥有我们渴望的一切。理解稀缺性与选择有助于我们在日常生活中做出更好、更明智的决策。
