经济学研究的是人们在资源有限时如何做出选择。对剑桥 Year 8 学生来说，利用暑假打下扎实基础能让这门学科变得有趣又轻松。本衔接课程将介绍核心概念、巩固关键技能并提供实用的学习策略，帮助你自信地迎接新学年。
1. What Is Economics? | 什么是经济学？
Economics is a social science that explores how individuals, businesses and governments allocate scarce resources to satisfy unlimited wants. It is divided into microeconomics, which focuses on single markets and decision-making, and macroeconomics, which looks at the whole economy including inflation, unemployment and growth.
经济学是一门社会科学，研究个人、企业和政府如何分配稀缺资源来满足无限的需求。它分为微观经济学（关注单个市场与决策）和宏观经济学（着眼于整体经济，包括通货膨胀、失业和增长）。
2. Scarcity and Choice | 稀缺性与选择
Scarcity is the fundamental economic problem: there are not enough resources to produce everything people want. Because of scarcity, individuals and societies must make choices. Every choice involves giving up something else, which leads to the idea of opportunity cost.
稀缺性是经济学的基本问题：没有足够的资源来生产人们想要的一切。由于稀缺，个人和社会都必须做出选择。每一个选择都意味着放弃另一样东西，这就引出了机会成本的概念。
3. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative forgone when a choice is made. For example, if you spend one hour studying economics instead of playing video games, the opportunity cost is the enjoyment lost from gaming. Understanding opportunity cost helps people make more informed decisions.
机会成本是指做出某个选择时所放弃的次优选择的价值。例如，如果你用一小时学习经济学而不是玩电子游戏，那么机会成本就是失去的游戏乐趣。理解机会成本有助于人们做出更明智的决定。
4. Resources and Factors of Production | 资源与生产要素
Economists classify resources into four factors of production: land (natural resources), labour (human effort), capital (man-made tools and machinery) and enterprise (the ability to combine the other factors and take risks). These factors are used to produce goods and services.
经济学家将资源分为四种生产要素：土地（自然资源）、劳动（人力付出）、资本（人造工具和机器）以及企业（整合其他要素并承担风险的能力）。这些要素被用来生产商品和服务。
5. Basic Economic Questions | 基本经济问题
Every economy must answer three basic questions: What to produce? How to produce? For whom to produce? The answers depend on the type of economic system. These questions arise because resources are scarce and have alternative uses.
每一个经济体都必须回答三个基本问题：生产什么？如何生产？为谁生产？答案取决于经济体制的类型。这些问题的产生是因为资源稀缺且有多种用途。
6. Demand and Supply | 需求与供给
Demand is the quantity of a good or service that consumers are willing and able to buy at different prices. Supply is the quantity that producers are willing and able to offer for sale. The interaction of demand and supply determines the market price and quantity traded.
需求是指消费者在不同价格下愿意并且能够购买的商品或服务的数量。供给是指生产者愿意并且能够提供出售的数量。需求与供给的相互作用决定了市场价格和交易量。
7. Markets and Prices | 市场与价格
A market is any arrangement that brings buyers and sellers together to exchange goods or services. Prices act as signals: when demand increases, prices tend to rise, encouraging producers to supply more. When supply exceeds demand, prices fall, clearing the market.
市场是将买家和卖家聚集在一起交换商品或服务的任何安排。价格起到信号作用：需求增加时价格往往上涨，鼓励生产者增加供给；当供给超过需求时价格下跌，市场得以出清。
8. Money and Exchange | 货币与交换
Money serves three main functions: a medium of exchange, a unit of account and a store of value. Without money, economies would rely on barter, which requires a double coincidence of wants – a much less efficient system. Modern money includes coins, notes and digital balances.
货币有三个主要功能：交换媒介、计价单位和价值储藏。没有货币，经济体就要依赖物物交换，这需要需求的双重巧合——这一体系效率低得多。现代货币包括硬币、纸币和数字余额。
9. Economic Systems | 经济体制
Societies organise their economies in different ways. In a market economy, decisions are made by private individuals and firms based on prices. In a planned economy, the government makes most economic decisions. Most real-world economies are mixed, combining elements of both.
社会以不同方式组织其经济。在市场经济中，决策由私人个体和企业在价格基础上作出。在计划经济中，政府作出大部分经济决策。大多数现实世界中的经济体是混合经济，兼具两者元素。
10. The Role of Government | 政府的角色
Governments intervene in the economy to correct market failures, provide public goods such as defence and street lighting, redistribute income through taxes and welfare, and stabilise the economy during recessions. Government policies include taxation, subsidies and regulation.
政府干预经济是为了纠正市场失灵，提供国防、街道照明等公共物品，通过税收和福利再分配收入，并在衰退期间稳定经济。政府政策包括税收、补贴和监管。
11. Personal Finance Basics | 个人理财基础
Young learners benefit from understanding budgeting, saving and spending wisely. A simple budget tracks income and expenses, helping people live within their means. Early financial literacy builds habits that lead to long-term economic well-being.
年轻学习者了解预算、储蓄和理性消费的基本知识大有裨益。一份简单的预算可以追踪收入与支出，帮助人们量入为出。早期的理财素养能培养习惯，带来长期的经济福祉。
12. Study Tips for Year 8 Economics | Year 8 经济学学习技巧
To succeed in Cambridge Year 8 Economics, keep a glossary of key terms with definitions and your own examples. Use real-world news to connect theory with practice. Draw simple demand and supply diagrams, and regularly test yourself with past questions. Discuss concepts with classmates to deepen understanding.
要在剑桥 Year 8 经济学中取得成功，准备一本关键词汇表，写上定义和你自己的例子；利用现实世界的新闻将理论与实践联系起来；绘制简单的供求图；定期用历年题目自我测试；与同学讨论概念以加深理解。
