1. What is Economics? | 什么是经济学？
Economics is the study of how people, businesses and governments make choices when resources are limited. It is not just about money; it is about making decisions in everyday life. For instance, a student deciding whether to spend an hour studying or playing video games is making an economic choice. Understanding economics helps you see the hidden costs and benefits behind every decision.
经济学研究的是人们、企业和政府在资源有限时如何做出选择。它不仅仅关乎金钱，更关乎日常生活中的决策。例如，一个学生在决定花一小时学习还是玩电子游戏时，就是在做经济选择。理解经济学能帮助你看到每个决定背后隐藏的成本与收益。
2. The Basic Economic Problem: Scarcity | 基本经济问题：稀缺性
The basic economic problem is that our wants are unlimited, but the resources to satisfy them are limited. This is called scarcity. Even the richest countries face scarcity because there are not enough workers, raw materials or time to produce everything people desire. Scarcity forces us to choose what to produce, how to produce it and for whom to produce it.
基本经济问题在于我们的欲望是无限的，而满足这些欲望的资源是有限的，这就被称为稀缺性。即便最富有的国家也面临稀缺，因为没有足够的劳动力、原材料或时间来生产人们想要的一切。稀缺性迫使我们做出选择：生产什么、如何生产以及为谁生产。
3. Needs and Wants | 需求与欲望
In economics, we separate needs from wants. Needs are essentials for survival, such as food, water, shelter and clothing. Wants are things we desire but can live without, like a new smartphone or a holiday. Recognising the difference helps individuals and governments set priorities when resources are scarce.
在经济学中，我们将需求与欲望区分开来。需求是生存的必需品，比如食物、水、住所和衣物。欲望是我们渴望但并非必需的东西，比如一部新手机或一次假期。认清二者的区别有助于个人和政府在资源稀缺时确定优先次序。
4. Opportunity Cost and Trade-offs | 机会成本与权衡
Every choice involves a trade-off: giving up one thing to get something else. The opportunity cost is the next best alternative you sacrifice. If a government spends £10 million on a new hospital, the opportunity cost might be the school or road that money could have built. Understanding opportunity cost helps us evaluate whether a decision is really worth it.
每个选择都涉及权衡：放弃一样东西去获得另一样。机会成本是你所牺牲的次优选项。如果政府花费 1000 万英镑建一家新医院，其机会成本可能就是那笔钱原本可以修建的学校或道路。理解机会成本有助于我们评估一个决定是否真的值得。
5. Factors of Production | 生产要素
To produce goods and services, we need four factors of production: land, labour, capital and enterprise. Land includes all natural resources like water, forests and minerals. Labour is the human effort, both physical and mental. Capital refers to man-made tools and machinery used in production. Enterprise is the ability to bring the other three factors together, taking risks to start new businesses.
要生产商品和服务，我们需要四种生产要素：土地、劳动、资本和企业才能。土地包括所有自然资源，如水、森林和矿产。劳动是人的努力，包括体力和脑力。资本指用于生产的人造工具和机器。企业才能是将其他三种要素结合起来的能力，并承担风险创办新企业。
6. Introduction to Markets: Demand and Supply | 市场初探：需求与供给
A market is any place where buyers and sellers meet to exchange goods or services. Demand is the quantity of a product consumers are willing and able to buy at different prices. Supply is the quantity producers are willing and able to sell. When you choose to buy a snack at the school canteen, you are participating in a market.
市场是买方和卖方相遇交换商品或服务的任何场所。需求是消费者在不同价格下愿意且能够购买的产品数量。供给是生产者愿意且能够出售的数量。当你在学校食堂选择购买零食时，你就在参与一个市场。
7. How Prices are Determined | 价格如何决定
Prices are mainly determined by the interaction of demand and supply. If many people want a product and it is scarce, the price tends to rise. If a product is abundant but few people want it, the price falls. The point where demand and supply meet is called the equilibrium price. Retailers like supermarkets adjust prices regularly to balance what customers want and what stock they have.
价格主要由需求与供给的相互作用决定。如果有很多人想要某个产品而它很稀缺，价格就会上涨。如果产品充足但很少人想要，价格就会下降。需求与供给相交的点称为均衡价格。超市等零售商定期调整价格，以平衡顾客的需求和库存量。
| Price per unit (p) | Quantity demanded | Quantity supplied |
|---|---|---|
| 10 | 100 | 20 |
| 20 | 80 | 40 |
| 30 | 60 | 60 |
| 40 | 40 | 80 |
The table shows how quantity demanded falls as price rises, while quantity supplied rises. The equilibrium price is 30p, where demand equals supply. At any other price, either a shortage or a surplus emerges.
该表格显示了价格上涨时需求量如何下降，而供给量如何上升。均衡价格为 30 便士，此时需求量等于供给量。在任何其他价格下，都会出现短缺或过剩。
8. Different Economic Systems | 不同的经济体制
Countries organise their economies in different ways. In a market economy, decisions are made by individuals and firms based on competition and prices. In a command economy, the government controls what is produced and how. Most countries today have a mixed economy, combining features of both, with governments providing services like education and healthcare while markets operate in other areas.
各国以不同方式组织其经济。在市场经济中，决策由个人和企业根据竞争和价格做出。在计划经济中，政府控制生产内容和方式。如今大多数国家实行混合经济，结合二者特点，政府提供教育和医疗等服务，而市场在其他领域运作。
9. Personal Finance and Budgeting | 个人理财与预算
Personal finance is the management of your own money, including income, saving and spending. A budget is a plan showing expected income and expenditure over a period. Learning to budget helps you avoid debt and save for future goals. For example, if you receive £20 pocket money each month and spend £5 on snacks and £10 on games, you can save £5 for a larger purchase.
个人理财是对自己资金的管理，包括收入、储蓄和支出。预算是显示一个时期预期收支的计划。学会做预算能帮助你避免债务，为未来目标储蓄。例如，如果你每月得到 20 英镑零花钱，5 英镑买零食，10 英镑买游戏，就可以存下 5 英镑用于更大的消费。
10. The Role of Government in the Economy | 政府在经济中的角色
Governments aim to keep the economy stable and fair. They collect taxes to pay for public services, such as roads, schools and the NHS. They also create rules to protect workers, consumers and the environment. When the economy is struggling, governments may increase spending or cut taxes to encourage growth. When prices rise too quickly, they might take steps to reduce inflation.
政府的目标是保持经济稳定和公平。他们通过征税来支付道路、学校和国民医疗服务等公共服务。他们还制定规则来保护劳动者、消费者和环境。当经济困难时，政府可能会增加支出或减税以刺激增长。当价格过快上涨时，他们可能会采取措施降低通胀。
11. Economic Skills: Interpreting Data | 经济技能：解读数据
Economists use graphs, charts and tables to analyse trends. You will learn to read line graphs showing changes in prices over time, and bar charts comparing production across countries. Simple calculations, such as percentages and averages, help you draw conclusions. Practice by looking at a household's weekly spending pie chart and identifying the largest expense category.
经济学家使用图形、图表和表格来分析趋势。你将学会阅读显示价格随时间变化的折线图，以及比较各国生产的条形图。简单的计算，如百分比和平均值，能帮助你得出结论。你可以通过观察一个家庭每周支出的饼图并找出最大的支出类别来进行练习。
12. Preparing for the Year Ahead | 为下一学年做准备
As you move into Year 8 Economics, you will build on these ideas by examining markets in more detail, exploring the role of financial institutions and studying how global trade works. To prepare, start observing economic news: listen to how petrol prices change, why shops hold sales, and what the Bank of England says about interest rates. Keep a simple diary of economic decisions you make each day – every choice tells an economic story.
在你升入 Year 8 经济学时，将在这些概念的基础上更详细地研究市场，探索金融机构的作用，并学习全球贸易的运作方式。为做好准备，可以开始观察经济新闻：留意汽油价格如何变化、商店为何举行促销，以及英格兰银行对利率的评论。每天记录你做出的经济决策——每一个选择都讲述着一个经济故事。
