1. What Is Economics? | 什么是经济学？
Economics is the study of how people make choices to manage scarce resources. It helps us understand why we have to decide how to use things like money, time, and materials. Every day, individuals, businesses, and governments face these decisions, and economics gives us the tools to analyse them.
经济学是研究人们如何做出选择以管理稀缺资源的学科。它帮助我们理解为什么我们需要决定如何使用金钱、时间和材料等事物。个人、企业和政府每天都要面对这些决策，而经济学为我们提供了分析这些决策的工具。
At its heart, economics is divided into two main branches. Microeconomics looks at the decisions made by individuals and firms, such as setting the price of a chocolate bar. Macroeconomics examines the economy as a whole, focusing on topics like unemployment, inflation, and the total output of a country.
经济学的核心分为两大分支。微观经济学关注个人和企业做出的决定，例如巧克力棒的定价。宏观经济学则把经济视为一个整体，聚焦于失业、通货膨胀和一个国家的总产出等主题。
2. Scarcity and Choice | 稀缺性与选择
Scarcity is the basic economic problem that never goes away. It means that our wants and needs are unlimited, but the resources to meet them are limited. Because we cannot have everything we want, we are forced to make choices.
稀缺性是永远存在的基本经济问题。它意味着我们的欲望和需求是无限的，但满足这些需求的资源却是有限的。因为我们无法拥有想要的一切，所以我们被迫做出选择。
For example, a student might have only two hours of free time after school. They must choose between doing homework, playing video games, or meeting friends. Similarly, a government with a fixed budget must decide whether to spend more on healthcare or education.
例如，一名学生放学后可能只有两小时的空闲时间。他们必须在做作业、打游戏或与朋友见面之间做出选择。同样，预算固定的政府必须决定是把更多资金用于医疗还是教育。
Scarcity leads to three fundamental questions every economy must answer: What goods and services should be produced? How should they be produced? For whom should they be produced? These questions shape the entire economic system.
稀缺性引出了每个经济体都必须回答的三个基本问题：应该生产哪些商品和服务？应该如何生产它们？它们应该为谁生产？这些问题塑造了整个经济体系。
3. Resources and Factors of Production | 资源与生产要素
To produce goods and services, an economy needs resources. These resources are grouped into four factors of production: land, labour, capital, and entrepreneurship. Understanding these factors helps explain how different countries grow and create wealth.
为了生产商品和服务，经济体需要资源。这些资源被分为四大生产要素：土地、劳动、资本和企业家才能。理解这些要素有助于解释不同国家如何实现增长并创造财富。
Land includes all natural resources found on the planet, such as forests, minerals, water, and fertile soil. Labour is the human effort, both physical and mental, used in production. Capital refers to the tools, machinery, and factories made by humans to produce other goods.
土地包括地球上所有的自然资源，如森林、矿产、水和肥沃的土壤。劳动是用于生产的人力，包括体力和脑力劳动。资本指的是人类制造的用于生产其他商品的工具、机器和工厂。
Entrepreneurship is the special skill of combining the other three factors to start a business and take risks. Entrepreneurs are the driving force behind innovation and job creation. The reward for each factor is rent for land, wages for labour, interest for capital, and profit for entrepreneurship.
企业家才能是将其他三种要素结合起来创业并承担风险的特殊技能。企业家是创新和创造就业的驱动力。每种要素的回报分别是：土地获得租金，劳动获得工资，资本获得利息，企业家才能获得利润。
4. Opportunity Cost | 机会成本
Whenever a choice is made, something is given up. The next best alternative that you sacrifice is called the opportunity cost. This concept is one of the most powerful tools in economics because it makes us think about the real cost of our decisions, not just the money we pay.
每当做出选择时，总有些东西被放弃。你所牺牲的次优替代选择就被称为机会成本。这个概念是经济学中最有力的工具之一，因为它让我们思考决策的真实成本，而不仅仅是我们支付了多少钱。
If you decide to spend £10 on a cinema ticket, the opportunity cost might be the new book or the ice cream sundae you could have bought instead. For a farmer who chooses to grow wheat on a field, the opportunity cost is the maize or potatoes they could have grown on the same land.
如果你决定花 10 英镑买一张电影票，机会成本可能是你本可以用这钱买到的新书或圣代冰淇淋。对于一个选择在田地里种小麦的农民来说，机会成本是同一块地上本可以种植的玉米或土豆。
Opportunity cost is not just about things you buy; it also applies to time. A professional footballer who spends an hour doing additional training might give up an hour of rest or family time. The value of that rest is the opportunity cost of the training session.
机会成本不仅关乎你购买的东西，也适用于时间。一名职业足球运动员花一小时做额外训练，可能就放弃了休息或与家人共处的一小时。那段休息的价值就是这次训练课的机会成本。
5. Supply and Demand | 供给与需求
Supply and demand are the twin forces that make a market economy work. Demand refers to how much of a good or service consumers are willing and able to buy at different prices. Supply is the amount producers are willing and able to sell at various prices.
供给与需求是让市场经济运转的两大力量。需求是指在不同价格下消费者愿意并且能够购买的商品或服务数量。供给则是指生产者在不同价格下愿意并且能够销售的数量。
The law of demand states that, all else being equal, as the price of a product rises, the quantity demanded falls. This is why you might think twice about buying a branded hoodie when its price jumps up. The law of supply says that as the price rises, the quantity supplied increases, because producers want to earn more profit.
需求定律指出，在其他条件不变的情况下，当产品价格上升时，需求量会下降。这就是为什么当品牌连帽衫价格飙升时，你可能会三思而后行。供给定律则表明，随着价格上升，供给量会增加，因为生产者希望获得更多利润。
The equilibrium price is where the quantity demanded equals the quantity supplied. At this price, the market clears and there is neither a surplus nor a shortage. If the price is set too high, a surplus occurs; if too low, a shortage occurs.
均衡价格是需求量等于供给量时的价格。在这个价格下，市场出清，既没有过剩也没有短缺。如果价格定得太高，就会出现过剩；如果定得太低，则会出现短缺。
6. Markets and Prices | 市场与价格
A market is any place where buyers and sellers come together to exchange goods, services, or resources. This can be a physical location like a farmers’ market, or a virtual space like an online auction site. Prices in a market act as signals that guide the decisions of both consumers and producers.
市场是买卖双方聚在一起交换商品、服务或资源的任何地方。它可以是一个像农贸市场那样的实体地点，也可以是一个像在线拍卖网站那样的虚拟空间。市场中的价格起着信号的作用，引导消费者和生产者的决策。
When demand for electric cars increases, the price may rise, signalling to car manufacturers to produce more. If the price of a crop like strawberries falls because there is a bumper harvest, consumers receive a signal to buy more, while farmers may decide to plant less next year.
当人们对电动汽车的需求增加时，价格可能会上涨，这向汽车制造商发出了要增产的信号。如果像草莓这样的作物因大丰收而价格下跌，消费者就会收到多买的信号，而农民则可能决定来年减少种植。
Different types of markets range from perfect competition, where many firms sell identical products, to monopolies, where a single firm dominates. The structure of a market affects how prices are set and how much power individual buyers and sellers have.
从众多企业销售同质产品的完全竞争市场，到由单一企业主导的垄断市场，市场类型多种多样。市场结构影响着价格如何制定，以及单个买卖双方拥有多大的力量。
7. Consumers and Producers | 消费者与生产者
Consumers are the individuals who buy and use goods and services to satisfy their needs and wants. Their role in the economy is vital because their spending drives demand. The main sectors where consumers spend their income include housing, food, transport, and entertainment.
消费者是购买和使用商品与服务以满足其需求和欲望的个人。他们在经济中扮演着至关重要的角色，因为他们的消费驱动着需求。消费者支出收入的主要领域包括住房、食品、交通和娱乐。
Producers, on the other hand, are the businesses that make goods or provide services. They combine factors of production to create output that they hope to sell at a profit. Producers must constantly make decisions about what to produce, how much to produce, and at what price to sell.
另一方面，生产者是制造商品或提供服务的企业。他们组合生产要素来创造产出，并希望以此出售获利。生产者必须不断决定生产什么、生产多少以及以什么价格出售。
The relationship between consumers and producers is interdependent. Without producers, consumers would have nothing to buy. Without consumers, producers would have no one to sell to. Producers often use advertising and branding to influence consumer preferences and build loyalty.
消费者与生产者之间的关系是相互依存的。没有生产者，消费者就无物可买。没有消费者，生产者就无人可售。生产者经常利用广告和品牌来影响消费者的偏好并建立忠诚度。
8. Economic Systems | 经济体系
An economic system is the way a society organises the production, distribution, and consumption of goods and services. The main types are market economies, command economies, and mixed economies. Each system answers the three basic economic questions differently.
经济体系是一个社会组织商品和服务的生产、分配和消费的方式。主要类型有市场经济、计划经济和混合经济。每种体系都以不同的方式回答三个基本经济问题。
In a pure market economy, decisions are made by individuals and firms through free markets with minimal government interference. Prices are determined by supply and demand. In a command economy, the government makes all the major decisions, owning most resources and setting production targets.
在纯市场经济中，决策由个人和企业通过自由市场做出，政府干预极少。价格由供需决定。在计划经济中，政府做出所有重大决策，拥有大部分资源，并设定生产目标。
A mixed economy combines elements of both the market and the government. Most modern economies, including the United Kingdom, are mixed economies. The government provides public goods like street lighting and defence, while private firms produce most consumer goods and services.
混合经济结合了市场和政府两方面的元素。大多数现代经济体，包括英国，都是混合经济。政府提供像路灯和国防这样的公共物品，而私营企业则生产大部分消费品和服务。
9. Personal Finance Basics | 个人理财基础
Personal finance is a practical application of economics that affects everyone. Learning to manage money wisely from an early age builds essential life skills. Key concepts include budgeting, saving, and understanding the difference between needs and wants.
个人理财是经济学在实践中的应用，影响着每一个人。从小学习明智地管理金钱能培养必要的生活技能。关键概念包括预算、储蓄，以及理解需要与欲望之间的区别。
A budget is a plan for how to spend and save money. By tracking income, such as pocket money or a part-time job, against expenses like snacks or cinema trips, you can avoid running out of money and start setting aside savings for a bigger goal.
预算是一份关于如何支出和储蓄的计划。通过记录收入（例如零花钱或兼职工作）和对照支出（例如零食或电影票），你可以避免把钱花光，并开始为更大的目标存钱。
An important rule for savers is the power of compound interest. If you save £100 in an account that pays 5% interest per year, after one year you have £105. The next year, you earn interest on £105, not just the original £100. Over many years, this effect can turn small, regular savings into a surprisingly large sum.
对于储蓄者来说，一条重要的法则是复利的威力。如果你把 100 英镑存入一个年利率 5% 的账户，一年后你会有 105 英镑。下一年，你将基于 105 英镑赚取利息，而不仅仅是原始的 100 英镑。经过多年，这种效应能把少量定期储蓄变成一笔惊人的巨款。
10. Building Economic Skills for GCSE | 为 GCSE 经济培养技能
As you move through Year 7, you are not only learning facts but also building the analytical skills that WJEC GCSE Economics requires. Start by reading business and economics news in simple formats. Even skimming headlines can help you connect what you learn in class to the real world.
随着你在七年级的学习，你不仅在学习知识，也在培养 WJEC GCSE 经济学所需的分析技巧。从阅读简单格式的商业与经济新闻开始吧。即使是浏览标题也能帮助你将课堂所学与现实世界联系起来。
Practise using economic vocabulary in your everyday conversations. For example, when choosing between buying a snack or saving the money, think out loud about the opportunity cost. Discuss with family members why the price of seasonal fruit changes and link it back to supply and demand.
练习在日常对话中使用经济学词汇。例如，在选择购买零食还是存钱时，大声思考其中的机会成本。与家人讨论季节性水果价格为何变化，并将其与供给和需求联系起来。
Try drawing simple supply and demand diagrams. Label the axes ‘Price’ and ‘Quantity’, draw a downward-sloping demand line and an upward-sloping supply line, and find the equilibrium. These diagrams will become an essential tool in your GCSE studies, and getting comfortable with them now is a great advantage.
尝试绘制简单的供需图。标出坐标轴“价格”和“数量”，画一条向下倾斜的需求线和一条向上倾斜的供给线，并找出均衡点。这些图表将成为你 GCSE 学习中的重要工具，现在就熟练运用它们将是一个巨大的优势。
