1. Why Study Economics in Year 7? | 为什么7年级要学习经济？
Economics helps you understand the world around you. Every time you decide how to spend your pocket money, choose a snack or save for a game, you are thinking like an economist. In Year 7, you will learn how resources are used to produce goods and services, how prices are set and why some people earn more than others. These ideas give you a toolkit to make better decisions in your own life and to understand news about jobs, taxes and trade.
经济学帮助你理解身边的世界。每次你决定如何花零花钱、选择零食或为游戏存钱时，你都在像经济学家一样思考。在7年级，你将学习如何利用资源生产商品和服务、价格如何确定以及为什么有些人比其他人挣得多。这些概念为你提供一套工具，让你在生活中做出更好的决策，也让你理解有关就业、税收和贸易的新闻。
2. The Basic Economic Problem: Scarcity | 基本经济问题：稀缺性
Economics starts with one big idea: scarcity. There are never enough resources to satisfy all our wants. Even the richest countries cannot produce everything their citizens would like to have. Because resources like time, money, workers and raw materials are limited, people must make choices. This is the basic economic problem every society faces — unlimited wants but limited resources.
经济学始于一个大观念：稀缺性。永远没有足够的资源来满足我们所有的欲望。即使是最富裕的国家也无法生产出国民想要的一切。由于时间、金钱、劳动力和原材料等资源是有限的，人们必须做出选择。这是每个社会都面临的基本经济问题——无限的欲望与有限的资源。
3. Needs and Wants | 需要与欲望
We can divide the things we buy into two groups: needs and wants. Needs are essential for survival, such as food, water, shelter and clothing. Wants are extra things that make life more enjoyable, like a new video game, a cinema ticket or designer trainers. Understanding the difference helps you see why you cannot have everything immediately and why you must prioritise some purchases over others.
我们可以把购买的东西分成两类：需要和欲望。需要是生存所必需的，如食物、水、住所和衣物。欲望是让生活更美好的额外事物，比如新电子游戏、电影票或名牌运动鞋。理解这个区别能帮助你明白为什么不能立刻拥有所有东西，以及为什么必须优先选择某些消费。
4. Goods and Services | 商品与服务
Businesses provide two main types of output: goods and services. Goods are physical items you can touch, such as a pencil, a bicycle or a loaf of bread. Services are activities done for you by other people, such as a haircut, a bus ride or a maths lesson. Both goods and services have a price and satisfy a want or a need. When you go shopping, you are choosing among different goods and services.
企业提供两种主要产出：商品和服务。商品是你可以触摸的实物，如铅笔、自行车或面包。服务是他人为你完成的活动，如理发、乘公交车或上数学课。商品和服务都有价格，都能满足欲望或需要。你去购物时，就是在不同的商品和服务之间做出选择。
5. Producers and Consumers | 生产者与消费者
In economics, a producer is a person or business that makes goods or provides services. A consumer is a person who buys and uses those goods and services. You are a consumer when you buy a snack; the shop is a producer of the retail service. Producers decide what to make based on what consumers want. This two‑way relationship drives the whole economy, creating jobs and income.
在经济学中，生产者是制造商品或提供服务的人或企业。消费者是购买并使用这些商品和服务的人。你买零食时就是消费者；商店就是零售服务的生产者。生产者根据消费者想要什么来决定生产什么。这种双向关系推动整个经济运转，创造就业和收入。
6. Factors of Production | 生产要素
To produce any good or service, four ingredients are needed. These are called the factors of production. First, land includes all natural resources like soil, water, oil and forests. Second, labour is the human effort, both physical and mental, used in making things. Third, capital means the tools, machines and buildings used to make other goods. Fourth, enterprise is the willingness of people to take risks and organise the other three factors to start a business. Together, these four factors make production possible.
要生产任何商品或服务，需要四种成分，称为生产要素。第一，土地包括所有自然资源，如土壤、水、石油和森林。第二，劳动力是生产过程中使用的人的体力和脑力。第三，资本是指用来生产其他商品的工具、机器和厂房。第四，企业家精神是人们愿意承担风险、组织其它三种要素来创业的意愿。这四个要素共同使生产成为可能。
- Land — natural resources
- Labour — human effort
- Capital — man‑made tools and machines
- Enterprise — risk‑taking and organisation
- 土地——自然资源
- 劳动力——人的努力
- 资本——人造的工具和机器
- 企业家精神——承担风险和组织
7. Making Choices: Opportunity Cost | 做出选择：机会成本
Whenever you make a choice, you give up something else. Opportunity cost is the value of the next best alternative you forget when you make a decision. For example, if you have £5 and you choose to buy a book instead of a cinema ticket, the opportunity cost of the book is the enjoyment you would have had from the film. Economists use this idea to explain that every choice has a real cost.
无论何时做出选择，你都在放弃其它东西。机会成本是你做决定时所放弃的次优选择的价值。例如，你手里有5英镑，选择买一本书而不是电影票，那么这本书的机会成本就是你从电影中本可以获得的享受。经济学家用这个概念解释每个选择都有真实的成本。
Opportunity Cost = The Next Best Alternative Forgone
机会成本 = 被放弃的次优选择
8. Introduction to Supply and Demand | 供需入门
Supply is the amount of a good or service that producers are willing to offer at different prices. Demand is the amount consumers are willing to buy. Usually, when the price is high, producers want to supply more, but consumers want to buy less. When the price is low, demand is high but supply may fall. The price in a market often settles where supply and demand meet. This simple model explains why the price of concert tickets can be so high and why supermarket bread is cheaper.
供给是生产者在不同价格下愿意提供的商品或服务数量。需求是消费者愿意购买的数量。通常，价格高时生产者想多供给，但消费者想少买。价格低时需求高而供给可能下降。市场价格往往在供需相等处稳定下来。这个简单模型解释了为什么演唱会门票价格那么高，而超市面包便宜得多。
9. How Markets Work | 市场如何运作
A market is any place — physical or online — where buyers and sellers come together to exchange goods, services or resources. Markets can be local, like a farmers' market, or global, like the market for oil. In a market economy, prices act as signals. If consumers want more of something, the price rises, telling producers to make more. If something is not selling, the price falls, telling producers to cut back. This system of price signals helps to coordinate the economy without anyone having to give orders.
市场是买卖双方聚集起来交换商品、服务或资源的任何地方——可以是实体的，也可以是在线的。市场可以是地方的，如农贸市场，也可以是全球的，如石油市场。在市场经济中，价格起着信号的作用。如果消费者想要更多某种东西，价格就会上涨，告诉生产者去生产更多。如果某样东西卖不出去，价格下跌，告诉生产者减少产量。这种价格信号系统有助于协调经济，无需任何人发号施令。
10. The Role of Money | 货币的作用
Before money, people used barter — swapping one good for another. That was inconvenient because you needed to find someone who wanted exactly what you had. Money solves this problem by acting as a medium of exchange, a store of value and a measure of worth. Today, money takes many forms, from coins and notes to digital payments. It makes buying and selling far easier and allows people to save for the future.
在货币出现之前，人们使用以物易物——用一种商品交换另一种。这很不方便，因为你必须找到正好需要你手中东西的人。货币通过充当交易媒介、价值储藏和衡量价值的尺度解决了这个问题。如今，货币有多种形式，从硬币、纸币到数字支付。它大大便利了买卖，也使人们能够为未来储蓄。
11. Economic Sectors | 经济部门
The economy can be divided into three main sectors. The primary sector extracts raw materials from nature — examples are farming, fishing, mining and forestry. The secondary sector turns raw materials into finished products, such as factories making cars, clothes or furniture. The tertiary sector provides services, including teaching, healthcare, retail and transport. All three sectors are connected; a loaf of bread begins with the farmer (primary), moves to the baker (secondary) and reaches you via the shop (tertiary).
经济可以分为三个主要部门。第一产业从自然界获取原材料——例如农耕、渔业、采矿和林业。第二产业将原材料转化为成品，如生产汽车、服装或家具的工厂。第三产业提供服务，包括教育、医疗、零售和运输。三个部门互相联系；一个面包从农民（第一产业）开始，经过面包师（第二产业），通过商店（第三产业）到达你手中。
12. Summer Learning Tips | 暑期学习小贴士
You do not need a textbook to start. Try these simple habits: keep a spending diary for a week, noting how you choose between wants and needs. Talk to your family about the decisions they make when shopping. Watch a short online video explaining supply and demand. Visit a local market and notice how prices differ between stalls. List five goods and five services you use in a day. These real‑world observations will make classroom economics feel familiar and fun.
你不需要教科书就可以开始。试试这些简单的习惯：记录一周的消费日记，记下你是如何在欲望和需要之间做出选择的。和家人聊一聊他们购物时的决策。观看一段解释供需的短视频。去一次本地市场，注意不同摊位价格如何变化。列出你一天使用的五种商品和五种服务。这些现实世界的观察会让课堂经济学变得熟悉又有趣。
