📚 KS3 WJEC Economics: Summer Preparation and Bridging Course | KS3 WJEC 经济：暑期预习与衔接课程
Summer offers the perfect opportunity to get a head start on Economics before entering KS3. This bridging guide introduces core economic concepts you will meet in the WJEC curriculum and helps you build confidence, curiosity and a real-world understanding of how people, businesses and governments make choices about limited resources.
暑假是提前接触经济学的最佳时机。本衔接指南将带你了解 WJEC 课程中的核心经济概念，帮助你建立信心、激发好奇心，并真正理解个人、企业和政府如何对有限资源做出选择。
1. What Is Economics? | 经济学是什么？
Economics is the study of how people use scarce resources to satisfy their unlimited wants. It looks at decisions made by individuals, families, businesses and governments. You will learn why we cannot have everything we want and how trade-offs shape the world around us.
经济学是研究人们如何利用稀缺资源来满足无限需求的学科。它涉及个人、家庭、企业和政府做出的决策。你会发现为什么我们不能拥有一切，以及权衡取舍如何塑造我们周围的世界。
At KS3, Economics often blends with financial education and citizenship. WJEC introduces you to the role of consumers, producers and the government in everyday life, preparing you for GCSE topics like microeconomics and macroeconomics.
在 KS3 阶段，经济学通常与理财教育和公民意识融合。WJEC 让你了解消费者、生产者和政府在日常生活中的角色，为微观经济学和宏观经济学等GCSE主题做好准备。
2. The Basic Economic Problem: Scarcity | 基本经济问题：稀缺性
Scarcity exists because resources are limited while human wants are unlimited. Even the richest countries face scarcity. This forces us to make choices — and every choice involves giving something up. Understanding scarcity is the foundation of all economic thinking.
稀缺性的存在是因为资源有限而人类需求无限。即使最富有的国家也面临稀缺。这迫使我们必须做出选择，而每个选择都意味着放弃某些东西。理解稀缺是整个经济学思维的基础。
In WJEC lessons, you will see scarcity applied to everything from pocket money to global oil supplies. The question is always: how do we allocate limited resources among competing uses?
在 WJEC 课堂上，你会看到稀缺性从零花钱到全球石油供应都有体现。核心问题始终是：我们如何在相互竞争的用途之间分配有限的资源？
3. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative you give up when making a choice. If you spend an hour playing video games, your opportunity cost might be studying or earning money from a small job. Economists measure cost by what is foregone, not just money spent.
机会成本是你在做出选择时所放弃的次优选项的价值。如果你花一小时打游戏，机会成本可能是学习或做零工赚钱。经济学家衡量成本不仅看花了多少钱，更看重放弃了什么。
This concept helps you evaluate decisions carefully. Whether a government spends more on healthcare or education, the trade-off can be analysed using opportunity cost. It encourages you to think about what you are sacrificing.
这个概念帮助你审慎评估决策。无论是政府在医疗保健还是教育上多花钱，都可以用机会成本分析取舍。它促使你思考自己牺牲了什么。
4. The Three Key Economic Questions | 三个关键经济问题
Every society must answer three fundamental questions: What to produce? How to produce? For whom to produce? These questions arise because of scarcity. Different economic systems answer them differently — through markets, government planning or a mix of both.
每个社会都必须回答三个基本问题：生产什么？如何生产？为谁生产？这些问题源于稀缺性。不同经济体系的回答方式不同——通过市场、政府计划或两者结合。
In the WJEC course, you will explore how the UK addresses these questions today. For example, supermarkets use demand data to decide what to stock, factories choose methods to keep costs low, and benefits and wages determine who gets goods.
在 WJEC 课程中，你将探索当今英国如何解决这些问题。例如，超市利用需求数据决定上架什么，工厂选择降低成本的生产方法，而福利和工资决定谁能获得商品。
5. Factors of Production | 生产要素
Resources used to produce goods and services are grouped into four factors: land (natural resources), labour (human effort), capital (machinery, tools, buildings) and enterprise (the risk-taking that organises the other three). Each factor earns a reward: rent, wages, interest and profit.
用于生产商品和服务的资源分为四种要素：土地（自然资源）、劳动力（人力）、资本（机器、工具、建筑）和企业精神（承担风险来组织其他三项）。每种要素都有回报：地租、工资、利息和利润。
Understanding factors of production helps you see how firms combine inputs to create output. A WJEC classroom task might involve identifying the factors used in a local bakery — flour (land), bakers (labour), ovens (capital) and the owner’s business idea (enterprise).
理解生产要素能让你明白企业如何组合投入来创造产出。WJEC 的课堂任务可能要求你辨认当地面包店所使用的要素——面粉（土地）、面包师（劳动力）、烤炉（资本）以及店主的创业构想（企业精神）。
6. Supply and Demand: How Prices Are Set | 供给与需求：价格如何决定
Demand is the amount of a good or service consumers are willing and able to buy at different prices. Supply is how much producers are willing and able to sell. Price is reached where supply equals demand — the equilibrium point. This simple model explains most everyday markets.
需求是消费者在不同价格下愿意并且能够购买的商品或服务数量。供给是生产者愿意并且能够出售的数量。当供给等于需求时，价格达到均衡点。这个简单模型解释了大多数日常市场。
For WJEC, you will draw and interpret simple supply and demand diagrams. If a new gaming console is released and demand surges while supply is fixed, price rises. If a harvest is huge, food prices may fall. These cause-and-effect chains are key to thinking like an economist.
在 WJEC 课程中，你将绘制和解读简单的供需图。如果新款游戏机发布，需求激增而供给固定，价格就会上涨。如果收成量大，食品价格可能下降。这些因果链条是像经济学家一样思考的关键。
7. Types of Markets and Competition | 市场类型与竞争
Markets can be highly competitive, with many buyers and sellers, or dominated by a single producer (monopoly). WJEC introduces you to these different structures. Competition tends to lower prices and improve quality, while a lack of competition can lead to high prices and poor service.
市场可能高度竞争，有众多买家和卖家；也可能被单一生产者（垄断）主导。WJEC 会介绍这些不同的结构。竞争往往能降低价格、提高质量，而缺乏竞争可能导致高价和差劣服务。
You will look at real examples such as supermarkets, energy companies and digital platforms. Understanding market power helps you as a consumer and shows why governments sometimes step in to regulate industries.
你会看到超市、能源公司和数字平台等真实例子。了解市场势力能帮助你作为消费者做出判断，也说明为什么政府有时要介入管制某些行业。
8. Money, Saving and Spending | 货币、储蓄与消费
Money is a medium of exchange, a store of value and a unit of account. Personal finance is a core WJEC topic at KS3: you learn how to budget, the difference between needs and wants, and why saving matters. Early habits in managing money can last a lifetime.
货币是交换媒介、价值储藏和计价单位。个人理财是 KS3 WJEC 的核心主题：你将学习如何做预算、区分需要与欲望，以及为什么储蓄很重要。早期养成理财习惯可以受益终生。
Pupils explore bank accounts, interest rates, and the risks of borrowing. Simple calculations show how savings grow with compound interest. Real-life scenarios, such as planning a school trip budget, make the theory practical.
学生将探索银行账户、利率以及借贷的风险。简单计算能展示储蓄如何通过复利增长。实际情景——如规划一次学校旅行预算——让理论变得实用。
9. The Role of Government in the Economy | 政府在经济中的角色
Government collects taxes and spends money on public services like education, healthcare and defence. It also creates rules to protect consumers, workers and the environment. At KS3, WJEC covers how the government influences the economy through taxation, spending and regulation.
政府征税并花钱投入教育、医疗和国防等公共服务。它还制定规则保护消费者、劳动者和环境。在 KS3，WJEC 涵盖政府如何通过税收、支出和监管影响经济。
Pupils discuss fairness in taxation and how public services benefit everyone, including those who cannot pay directly. You may debate whether a new local sports centre should be funded by council taxes or private investors.
学生讨论税收公平以及公共服务如何惠及所有人，包括无力直接支付的人。你或许会辩论：一个新的当地体育中心应该由市政税还是私人投资者来出资。
10. International Trade and Globalisation | 国际贸易与全球化
No country produces everything it needs. Trade allows nations to specialise in what they do best and exchange the surplus. WJEC introduces the idea of imports, exports and why we buy goods from other countries. Globalisation connects economies around the world.
没有任何国家能生产自身所需的一切。贸易让各国能专门生产自己最擅长的产品，并用剩余进行交换。WJEC 介绍进出口概念，以及为什么我们要从其他国家购买商品。全球化将世界各地的经济连接起来。
You will learn how everyday items, like a smartphone, involve many countries in their design, component supply and assembly. Discussions cover benefits of cheaper goods and concerns about local job losses.
你将了解到日常物品——比如一部智能手机——在设计、零部件供应和组装中涉及多个国家。课堂讨论会涉及更廉价商品的好处以及对本地就业岗位流失的担忧。
11. Bridging to GCSE Economics: Key Study Skills | 衔接 GCSE 经济学：核心学习技能
Moving from KS3 to GCSE Economics requires strong analytical and evaluation skills. Summer bridging is about more than learning definitions — practise reading news headlines, spotting economic concepts and asking “why?”. Keep a simple glossary of new terms like “inflation” or “productivity”.
从 KS3 过渡到 GCSE 经济学需要较强的分析与评估能力。暑期衔接不仅仅在于背诵定义——练习阅读新闻标题，辨认经济概念并追问“为什么”。为“通货膨胀”“生产率”等新术语准备一个简单词汇表。
Create mind maps linking topics, and try writing one-paragraph answers to “Explain…” questions. WJEC mark schemes reward clear chains of reasoning and real-world examples, so start collecting articles or podcasts that interest you.
绘制联系各主题的思维导图，并试着为“解释……”类题目写一两个段落的答案。WJEC 评分方案奖励清晰的推理链条和现实例子，所以现在就可以开始收集你感兴趣的文章或播客。
12. Summer Activities to Spark Economic Thinking | 激发经济思维的暑期活动
You do not need a textbook to start thinking like an economist. Play board games like Monopoly to understand property and rent. Set up a small enterprise — a lemonade stand or car wash — to experience costs, prices and profit. Watch age-appropriate documentaries on trade and technology.
想开始像经济学家一样思考，并不需要教科书。玩大富翁这样的棋盘游戏来理解地产和租金。办一个卖柠檬水或洗车的小生意，体验成本、价格和利润。观看关于贸易和科技的适龄纪录片。
Discuss everyday choices with family: why does a supermarket put sweets near the till? Why is petrol more expensive in rural areas? These conversations build the curiosity that will make your GCSE Economics journey exciting and enjoyable.
和家人讨论日常选择：为什么超市把糖果放在收银台旁边？为什么乡村地区的汽油更贵？这些对话会培养好奇心，让你的 GCSE 经济学之旅既精彩又愉快。
