欢迎来到经济学的世界！这份暑期衔接指南旨在帮助七年级学生自信地迈入 CIE 经济学课程。我们将探索基础概念，学习像经济学家一样思考，并理解这门学科为何在日常生活中如此重要。读完本文，你将感到准备充分、充满好奇，并迫不及待地迎接未来的挑战。
1. What is Economics? | 什么是经济学？
Economics is the study of how people make choices when resources are limited. It looks at how individuals, families, businesses, and governments decide what to buy, what to produce, and how to distribute goods and services. At its heart, economics asks: ‘What is the best use of the things we have?’
经济学是研究人们在资源有限的条件下如何做出选择的学科。它关注个人、家庭、企业和政府如何决定买什么、生产什么，以及如何分配商品和服务。其核心问题在于：“我们所拥有的一切，如何发挥最佳用途？”
Every day you make economic decisions — whether to save your pocket money or spend it, how much time to dedicate to homework versus hobbies. Once you start noticing, you will see economics everywhere: from the queues at the school canteen to the price of a new video game.
你每天都在做经济决策——是存下零花钱还是花出去，花多少时间做作业、多少时间发展爱好。一旦开始留意，你会发现经济学无处不在：从学校食堂的排队现象到新款游戏的价格都是如此。
2. Why Study Economics in Year 7? | 为什么在七年级学习经济学？
Starting Economics in Year 7 builds a strong foundation for later years and for understanding the world. CIE’s curriculum encourages you to explore real-life issues like poverty, trade, and environmental sustainability. Early exposure helps you develop critical thinking, data interpretation, and decision-making skills that are useful across all subjects.
在七年级开始学习经济学，能为高年级和认识世界打下坚实基础。CIE 课程鼓励你探索现实生活中的问题，如贫困、贸易和环境可持续性。提前接触有助于培养批判性思维、数据解读和决策能力，这些技能在所有学科中都有用。
Moreover, economics explains why some countries are rich while others struggle, why prices rise and fall, and how your choices affect your future. It turns you into a more informed citizen who can understand news headlines and participate in discussions about important issues.
此外，经济学会解释为什么有些国家富裕而有些国家困窘，为什么价格会涨会跌，以及你的选择如何影响未来。它能让你变成更明智的公民，理解新闻标题，参与重要议题的讨论。
3. The Fundamental Economic Problem: Scarcity | 基本经济问题：稀缺性
The central problem in economics is scarcity. Scarcity means that resources are limited while human wants are unlimited. No country, no matter how wealthy, has enough resources to produce everything everyone desires. This forces people and societies to make choices about what to produce, how to produce it, and for whom to produce it.
经济学的核心问题是稀缺性。稀缺性意味着资源是有限的，而人类的欲望是无穷的。没有任何国家，无论多富裕，拥有足够的资源来生产每个人想要的一切。这迫使人们和社会做出选择：生产什么、如何生产、为谁生产。
Resources include land, labour, capital, and entrepreneurship — often called the factors of production. Because these are scarce, we must decide how to allocate them efficiently. A simple example: a farmer has a small piece of land. Should they grow wheat or vegetables? This choice involves scarcity.
资源包括土地、劳动力、资本和企业家才能——通常被称为生产要素。由于它们是稀缺的，我们必须决定如何有效配置它们。举个简单的例子：一位农民有一小块土地，他应该种小麦还是蔬菜？这个选择就涉及稀缺性。
4. Opportunity Cost: The Value of Choice | 机会成本：选择的价值
Whenever you make a choice, you give up the next best alternative. This sacrifice is called opportunity cost. It is not always about money — it can be time, effort, or enjoyment. For instance, if you spend an hour playing video games instead of studying, the opportunity cost is the learning you could have gained in that hour.
每当你做出一个选择，你就放弃了次优的那个替代选项。这种牺牲被称为机会成本。它不仅关乎金钱——也可能是时间、精力或快乐。例如，如果你花一小时玩游戏而不是学习，机会成本就是那一小时原本可以学到的知识。
Understanding opportunity cost helps you evaluate decisions more carefully. Businesses consider it when choosing between investments. Governments weigh the opportunity cost of spending on healthcare versus education. Even as a Year 7 student, you can use it to decide how to use free time wisely.
理解机会成本有助于你更仔细地权衡决策。企业在选择投资方案时会考虑它。政府会衡量把钱花在医疗还是教育上的机会成本。即使作为一名七年级学生，你也可以用它来明智地安排闲暇时间。
5. Understanding Needs and Wants | 理解需要与想要
Economists distinguish between needs and wants. Needs are things essential for survival, such as food, water, shelter, and clothing. Wants are things we desire but can live without, like toys, entertainment, or luxury items. This distinction is crucial because scarcity forces us to prioritise needs over wants.
经济学家区分需要与想要。需要是生存必不可少的东西，如食物、水、住所和衣物。想要是我们渴望但并非生存必需的东西，比如玩具、娱乐或奢侈品。这一区分至关重要，因为稀缺性迫使我们优先满足需要而非想要。
However, the line between needs and wants can blur depending on context. A smartphone might be a want for an adult but could be seen as a need for a student in a digital learning environment. In Economics, you’ll learn to think critically about such classifications and how they influence spending patterns.
然而，需要和想要的界限会因情境而模糊。对成年人来说，智能手机可能是想要，但在数字学习环境下，对于学生来说可能被视为需要。在经济学中，你将学会批判性地思考这种分类，以及它们如何影响消费模式。
6. Goods and Services | 商品与服务
Economies produce two main types of output: goods and services. Goods are physical items you can touch, like books, apples, or bicycles. Services are activities performed for you, such as teaching, haircuts, or bus rides. Both satisfy human wants but in different ways.
经济体生产两大类产出：商品和服务。商品是你可以触摸到的物品，如书籍、苹果或自行车。服务是为你所做的活动，如教学、理发或巴士出行。两者都能满足人的欲望，但方式不同。
Goods can be further divided into consumer goods (used by individuals) and capital goods (used by businesses to make other products). Services, on the other hand, are intangible — you cannot hold them, but you experience their benefits. Together, they form the backbone of any economy.
商品还可细分为消费品（个人使用）和资本品（企业用来制造其他产品的设备）。服务则是无形的——你无法握住它，但能体验到其益处。两者共同构成了任何经济体的支柱。
7. Production and Factors of Production | 生产与生产要素
To produce goods and services, we need inputs called factors of production. These are land (natural resources), labour (human effort), capital (man-made tools and machinery), and entrepreneurship (the ability to combine the other factors and take risks). Each factor earns a reward: rent, wages, interest, and profit respectively.
要生产商品和服务，我们需要投入生产要素。它们包括土地（自然资源）、劳动力（人力付出）、资本（人造工具和机械）以及企业家才能（组合其他要素并承担风险的能力）。每种要素分别获得报酬：地租、工资、利息和利润。
Production also involves adding value — transforming raw materials into finished products that are worth more. A baker turns flour, water, and yeast into bread. The difference between the cost of inputs and the price of bread is the value added. This concept helps you understand why some businesses succeed while others fail.
生产还涉及增值——将原材料转化为更有价值的成品。面包师把面粉、水和酵母变成面包。投入成本与面包售价之间的差额就是增值。这一概念有助于理解为什么一些企业成功而另一些失败。
8. Introduction to Supply and Demand | 供需入门
Supply and demand are the driving forces of markets. Demand refers to how much of a product consumers are willing and able to buy at different prices. Generally, when prices fall, demand rises (and vice versa). Supply refers to how much producers are willing to sell at different prices — usually, higher prices encourage more supply.
供给与需求是市场的驱动力。需求是指消费者在不同价格下愿意且能够购买的产品数量。通常，价格下跌时，需求上升（反之亦然）。供给是指生产者在不同价格下愿意并能够出售的数量——通常情况下，价格越高，供给越多。
The interaction of supply and demand determines the market price and quantity traded. If demand for ice cream increases in summer, the price may rise. If a new technology makes production cheaper, supply increases and price may fall. These simple ideas explain a huge range of real-world changes.
供需的相互作用决定了市场价格和交易数量。如果夏天冰淇淋需求增加，价格可能上涨。如果新技术使生产更便宜，供给增加，价格可能下降。这些简单概念能解释大量现实世界的变化。
9. How Markets Work | 市场如何运作
A market is any place or system where buyers and sellers come together to exchange goods, services, or resources. Markets can be physical (like a farmers’ market) or virtual (like an online store). Prices in a market act as signals — when a price is high, it tells producers there is an opportunity for profit, and more enter the market.
市场是买卖双方聚集在一起交换商品、服务或资源的任何场所或系统。市场可以是有形的（如农贸市场），也可以是虚拟的（如网上商店）。市场价格充当信号——价格高时，告诉生产者有利可图，于是更多人进入市场。
Competition plays a vital role in markets. It encourages businesses to improve quality, lower costs, and innovate. Without competition, monopolies could charge high prices and reduce choice. CIE students will explore how markets can work efficiently or fail, and what governments can do about it.
竞争在市场里起着至关重要的作用。它能促使企业提高质量、降低成本并创新。若没有竞争，垄断者可能会收取高价并减少选择。CIE 学生将探索市场如何高效运作或失灵，以及政府可以对此采取什么措施。
10. The Role of Money | 货币的作用
Money is more than just coins and notes. It serves three main functions: a medium of exchange (we use it to buy things), a unit of account (it measures the value of goods), and a store of value (it can be saved for future use). Without money, we would have to rely on barter, which is inefficient and inconvenient.
货币不仅仅是硬币和钞票。它有三大职能：交换媒介（用来买东西）、计价单位（衡量商品价值）和价值储藏（可储存供将来使用）。没有货币，我们就只能依赖以物易物，但这既低效又不方便。
Modern economies also use electronic money and digital payments. Understanding money helps you make sense of saving, spending, and even the concept of inflation — where prices generally rise over time. Early financial literacy is a key skill that Economics develops.
现代经济体还使用电子货币和数字支付。理解货币有助于你理解储蓄、消费，甚至通货膨胀的概念——即物价随时间的普遍上涨。早期的金融素养是经济学培养的一项关键技能。
11. Economic Decision-Making | 经济决策
Economic agents — individuals, firms, and governments — constantly make decisions under conditions of scarcity. Individuals decide how to allocate their income between consumption and saving. Firms decide what to produce and how to price it. Governments decide how to spend tax revenue and which public services to provide.
经济主体——个人、企业和政府——在稀缺条件下不断做出决策。个人决定如何将收入分配在消费和储蓄之间。企业决定生产什么以及如何定价。政府决定如何使用税收收入，提供哪些公共服务。
All these decisions involve trade-offs and opportunity costs. A student choosing between two after-school clubs faces an opportunity cost. A government building a new road may have to reduce spending on schools. Recognising these trade-offs gives you a powerful framework for analysing choices.
所有这些决策都涉及权衡与机会成本。一名学生在两个课后社团之间做选择，就面临机会成本。政府修建新公路，可能不得不削减学校开支。认识到这些权衡能为你提供一个有力的分析选择框架。
12. Tips for Summer Preparation and Bridging | 暑期预习与衔接建议
To get the most out of your Year 7 Economics journey, start by observing the world around you. Keep a simple ‘Economics diary’ where you note down questions like: Why are concert tickets so expensive? Why do some shops offer discounts? Read news headlines about trade, jobs, or prices and try to connect them to the concepts above.
要充分利用你的七年级经济学之旅，可以先从观察周围的世界开始。写一本简单的“经济学日记”，记下诸如此类的问题：为什么演唱会门票这么贵？为什么有些商店会打折？阅读关于贸易、就业或价格的新闻标题，尝试与上述概念联系起来。
Watch educational videos aimed at beginners, and discuss interesting examples with family. You do not need to master everything now — just build curiosity. Our bridging course will revisit all these topics with real data and case studies, making your transition into CIE Economics smooth and enjoyable.
观看面向初学者的教育视频，并与家人讨论有趣的例子。你现在不需要掌握一切——只需培养好奇心。我们的衔接课程将通过真实数据和案例重温所有这些主题，使你的 CIE 经济学过渡过程既顺畅又愉快。
