1. What is Economics? | 经济学是什么？
Economics is the study of how people and society use scarce resources to satisfy unlimited wants. In Year 8 WJEC Economics, you will begin by exploring this fundamental problem of scarcity. You will learn that we cannot have everything we want, so we must make choices. These choices involve trade-offs, and economists use models and graphs to explain how decisions are made by consumers, producers and governments. The subject is divided into two main branches: microeconomics, which looks at individuals and businesses, and macroeconomics, which deals with the economy as a whole. Understanding this basic definition sets the stage for everything else you will study.
经济学研究的是人类和社会如何使用稀缺资源来满足无限的需求。在 Year 8 WJEC 经济课程中，你将首先探讨这个关于稀缺性的基本问题。你会学到，我们无法拥有想要的一切，因此必须做出选择。这些选择涉及权衡取舍，经济学家通过模型和图表来解释消费者、生产者和政府是如何做决策的。这门学科分为两个主要分支：微观经济学关注个人和企业，宏观经济学则着眼于整个经济体。理解这个基本定义会为你之后的学习打好基础。
2. Scarcity and Choice | 稀缺性与选择
Scarcity is the central economic problem. It means that there are limited resources – land, labour, capital and enterprise – but the things people want (goods and services) are unlimited. Because of scarcity, every society must answer three basic questions: what to produce, how to produce it and for whom to produce it. In Year 8, you will encounter simple examples like a farmer deciding whether to grow wheat or potatoes on a limited field. The farmer cannot grow both fully, so a choice has to be made. Every choice involves giving up something else, which leads to the important concept of opportunity cost.
稀缺性是经济学的核心问题。它意味着资源（土地、劳动力、资本和企业家才能）是有限的，而人们想要的商品和服务却是无限的。由于稀缺性的存在，每个社会都必须回答三个基本问题：生产什么、如何生产以及为谁生产。在 Year 8，你会遇到一些简单例子，比如一个农民必须在有限的田地上决定种小麦还是种土豆。他无法两种作物都种满，因此必须做出选择。每一个选择都意味着放弃其他东西，这就引出了机会成本这一重要概念。
3. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative that you give up when you make a choice. It is not necessarily about money; it is about the benefits you could have enjoyed from the foregone option. For example, if you decide to spend your Saturday afternoon studying economics instead of playing football, the opportunity cost is the enjoyment and fitness gains from playing football. In WJEC Year 8 Economics, you will learn to identify opportunity costs in everyday decisions, such as spending pocket money on a cinema ticket instead of saving it. This concept helps you think like an economist by weighing up alternatives.
机会成本是指当你在做出选择时所放弃的次优替代品的价值。它不一定与金钱有关，而是指从被放弃的选项中所能获得的收益。例如，如果你决定用周六下午学习经济学而不是踢足球，那么机会成本就是踢足球所带来的快乐和身体锻炼的收益。在 WJEC Year 8 经济学中，你将学会识别日常决策中的机会成本，比如用零花钱买电影票而不是存起来。这个概念帮助你像经济学家一样进行权衡，从而做出更好的选择。
4. Needs and Wants | 需要与想要
People have needs and wants. Needs are essential for survival, such as food, water, shelter and clothing. Wants are desires that are not essential for survival but make life more comfortable or enjoyable, like the latest smartphone, a holiday trip or a sports car. In Year 8 Economics, distinguishing between needs and wants is crucial because it influences how consumers spend their income and how businesses target their products. As societies become wealthier, the line between needs and wants can become blurred, but fundamentally, needs are limited while wants are unlimited, which is what drives scarcity.
人类既有需要也有想要。需要是生存所必需的，比如食物、水、住所和衣物。想要则是那些并非生存必须、却能让生活更舒适或更有乐趣的欲望，例如最新款的智能手机、一次度假旅行或一辆跑车。在 Year 8 经济学中，区分需要和想要至关重要，因为它影响着消费者如何分配收入以及企业如何定位产品。随着社会变得更加富裕，需要和想要的界限可能会变得模糊，但在本质上，需要是有限的，而想要是无限的，这正是稀缺性产生的根本原因。
5. Goods and Services | 商品与服务
In economics, we consume goods and services to satisfy our needs and wants. Goods are tangible items you can see and touch, such as a bicycle, a book or a bottle of juice. There are two main types of goods: consumer goods, which directly satisfy wants (like a chocolate bar), and capital goods, which are used to produce other goods (like a factory machine). Services are intangible acts that people do for others, such as a haircut, a bus journey or a teacher’s lesson. In Year 8 WJEC, you will learn to classify examples of goods and services, and understand that both contribute to a country’s economic output.
在经济学中，我们消费商品和服务来满足自己的需要和想要。商品是你可以看见和触摸的有形物品，比如自行车、书籍或一瓶果汁。商品主要分为两类：消费品（如巧克力棒，直接满足需求）和资本品（如工厂机器，用于生产其他商品）。服务则是人们为他人提供的无形活动，例如理发、乘坐巴士或老师授课。在 WJEC Year 8 经济学中，你将学会将现实中的例子归类为商品或服务，并理解两者共同构成了一个国家的经济产出。
6. Factors of Production | 生产要素
To produce goods and services, four factors of production are needed: land, labour, capital and enterprise. Land refers to all natural resources, including fields, minerals, water and forests. Labour is the human effort, both physical and mental, put into production. Capital means man-made resources used in production, such as machinery, tools and factories; this is different from financial capital (money). Enterprise is the willingness of individuals to take risks and combine the other three factors to start a business. In Year 8, you will learn how these factors work together and why they are limited, which again links back to scarcity.
为了生产商品和服务，需要四种生产要素：土地、劳动力、资本和企业家才能。土地指所有自然资源，包括田产、矿产、水源和森林。劳动力是投入到生产中的人力，包括体力和脑力劳动。资本指用于生产的人造资源，如机器、工具和工厂；这不同于金融资本（金钱）。企业家才能是指个人愿意承担风险，将其他三种要素组合起来创办企业的能力。在 Year 8，你将学习这些要素如何协同工作，以及为什么它们是有限的，这再次与稀缺性联系了起来。
7. Introduction to Supply and Demand | 供需入门
Supply and demand are two of the most powerful concepts in economics. Demand refers to how much of a good or service consumers are willing and able to buy at different prices. Generally, as the price of a good falls, the quantity demanded increases – this is the law of demand. Supply refers to how much producers are willing and able to sell at different prices. According to the law of supply, as the price rises, the quantity supplied increases. In Year 8 WJEC, you will draw simple demand and supply curves and see how they intersect to determine the market price. Even a basic understanding of this model will give you a huge advantage when starting the course.
供需是经济学中最强大的两个概念。需求指消费者在不同价格水平上愿意并且能够购买的商品或服务数量。通常，当商品价格下降时，需求量会上升——这就是需求定律。供给指生产者在不同价格水平上愿意并且能够出售的数量。根据供给定律，价格上升时，供给量增加。在 WJEC Year 8 经济学中，你将绘制简单的需求曲线和供给曲线，并看到它们如何相交来决定市场价格。即使是对这个模型有基本的理解，也会让你在开始学习课程时占据巨大优势。
8. The Market and Equilibrium | 市场与均衡
A market is any place or mechanism where buyers and sellers meet to exchange goods and services. It can be a physical location like a fruit market or an online platform like a game trading website. The equilibrium price is the price where the quantity demanded equals the quantity supplied. At this point, there is no shortage (excess demand) and no surplus (excess supply). If the price is above equilibrium, a surplus occurs and producers may lower prices to clear stock. If the price is below equilibrium, a shortage occurs and prices tend to rise. Year 8 students will learn to explain these situations using simple real-world examples, such as ticket sales for a popular concert or the price of seasonal fruits.
市场是买卖双方相遇并交换商品和服务的任何场所或机制。它可以是一个实体地点，比如水果市场，也可以是一个在线平台，比如游戏交易网站。均衡价格是指需求量等于供给量时的价格。在均衡点上，不存在短缺（超额需求）和过剩（超额供给）。如果价格高于均衡点，就会出现过剩，生产者可能会降低价格以清理库存。如果价格低于均衡点，就会出现短缺，价格往往会上升。Year 8 学生将学会用简单的现实案例来解释这些情况，比如热门演唱会的门票销售或季节性水果的价格。
9. Types of Economies | 经济体系类型
Different societies have different ways of organising economic activity. In Year 8 WJEC, you will be introduced to three primary economic systems: the market economy, the planned (command) economy and the mixed economy. In a pure market economy, decisions about what to produce are made by private individuals and businesses based on supply and demand, with little government interference. In a planned economy, the government controls all major decisions about production and distribution. Most modern economies, including the UK, are mixed economies where both the state and the private sector play important roles. Understanding these systems helps you appreciate how political and economic choices shape the world around you.
不同的社会有着不同的经济活动组织方式。在 WJEC Year 8 经济学中，你将会接触到三种基本的经济体系：市场经济、计划经济（指令经济）和混合经济。在纯粹的市场经济中，生产什么由个人和企业根据供需决定，政府干预很少。在计划经济中，政府掌控生产和分配的所有重大决策。包括英国在内的大多数现代经济体都是混合经济，国家和私有部门都扮演着重要角色。理解这些制度能帮助你认识到政治和经济决策如何塑造我们周围的世界。
10. Money and Exchange | 货币与交换
Money plays a vital role in any economy. Before money existed, people traded goods directly, which is called barter. Barter requires a ‘double coincidence of wants’, meaning both parties must want what the other offers. Money solves this problem by acting as a medium of exchange, a unit of account and a store of value. In Year 8, you will learn about the functions of money and why modern banknotes, coins and digital payments are widely accepted. You will also touch on the idea of personal finance, learning how budgeting helps you manage limited pocket money to achieve your goals, connecting back to the concepts of choice and opportunity cost.
货币在任何经济体中都扮演着至关重要的角色。在货币出现以前，人们直接交换物品，这叫作物物交换。物物交换需要“需求的双重巧合”，意思是双方必须同时想要对方提供的东西。货币通过充当交换媒介、计价单位和价值储藏手段解决了这个问题。在 Year 8，你将学习货币的功能，以及为什么现代的纸币、硬币和数字支付方式被广泛接受。你还会接触到个人理财的概念，学习如何通过预算管理有限的零花钱来实现自己的目标，再次与选择和机会成本的概念联系起来。
11. How to Prepare Over the Summer | 暑期预习指南
To get a flying start in Year 8 Economics, you do not need a heavy textbook straightaway. Summer preparation can be engaging and light. Start by observing the world around you with an economic lens: notice price tags in shops, ask yourself why some products are more expensive than others, or keep a simple diary of your own spending decisions. Watch short, age-appropriate educational videos on supply and demand or play online simulation games that mimic running a business. Making a glossary of key terms such as scarcity, opportunity cost, demand and supply can serve as an excellent reference when term begins. The aim is to build curiosity, not to memorise everything.
想要在 Year 8 经济学学习中取得先机，你并不需要一开始就啃厚重的教科书。暑期的准备工作可以充满趣味且轻松。首先用经济学的视角观察你周围的世界：留意商店里的价格标签，问问自己为什么有些产品比其他产品贵，或者简单记录你自己的消费决策。观看适合你年龄的有关供需的短视频，玩一些模拟经营企业的在线模拟游戏。制作一份包含稀缺性、机会成本、需求和供给等关键术语的词汇表，可以在开学后成为出色的参考资料。目标是培养好奇心，而不是死记硬背。
12. Bridging from Year 8 to Year 9 Economics | 从 Year 8 到 Year 9 的衔接
Year 8 WJEC Economics provides a solid foundation that will be built upon in Year 9 and beyond. The skills you begin to develop – reading data, interpreting simple graphs, considering alternative viewpoints – are not just academic exercises; they are life skills. By the end of Year 8, you should be comfortable explaining why economists study choices, how markets work and what governments can do to influence economic outcomes. When you move into Year 9, you will delve deeper into topics like business costs, competition, government spending and taxation, and perhaps even international trade. If you have taken the time to master the core concepts over the summer and during Year 8, you will find the progression smooth and enjoyable.
WJEC Year 8 经济学为你打下了坚实的基础，这些知识将在 Year 9 及以后的学习中不断深化。你开始培养的技能——阅读数据、解读简单图表、考虑不同观点——不仅仅是课堂练习，更是生活技能。到 Year 8 结束时，你应该能够自如地解释经济学家为什么研究选择、市场如何运作以及政府能够采取哪些措施来影响经济结果。当进入 Year 9，你将更深入地学习企业成本、竞争、政府支出与税收，甚至可能涉及国际贸易等话题。如果你利用暑假和 Year 8 的学习时间掌握了这些核心概念，就会发现衔接过程顺利而愉快。
