进入中学是一个激动人心的里程碑，七年级的第一次经济学体验将让你看清世界真实运转的方式。这个暑期衔接课程旨在帮助你提前掌握AQA经济学课程中的关键概念，从稀缺与选择到供给与需求。你将建立信心、积累新词汇，并发现经济学不仅仅是关于金钱——它关乎我们每天做出的每一个决策。
1. Welcome to Economics: Why Study It? | 欢迎来到经济学：为什么学习它？
Economics is often called the science of decision-making. It helps us understand how individuals, businesses, and governments allocate limited resources to satisfy unlimited wants. In Year 7, you will start to see the world through an economist’s eyes, noticing trade-offs everywhere.
经济学常被称为决策的科学。它帮助我们理解个人、企业和政府如何分配有限的资源来满足无限的需求。在七年级，你将开始用经济学家的眼光看世界，发现生活中处处存在权衡。
Studying economics is not just about preparing for exams; it equips you with critical thinking skills. You will learn to question headlines, evaluate arguments, and make smarter personal choices. Every time you decide how to spend your pocket money or your time, you are already thinking like an economist.
学习经济学不仅是为了考试，更是为了培养批判性思维。你将学会质疑新闻标题、评估论点，并做出更明智的个人选择。每当你决定如何花零用钱或支配时间时，你已经是在像经济学家一样思考了。
2. Scarcity: The Fundamental Economic Problem | 稀缺性：基本经济问题
Scarcity means that we have limited resources but unlimited wants. This is the central problem in economics. Whether it is time, money, or raw materials, there is never enough to satisfy everyone’s desires completely.
稀缺性意味着我们的资源有限，但需求无限。这是经济学的核心问题。无论是时间、金钱还是原材料，永远无法完全满足每个人的所有欲望。
Because of scarcity, we must make choices. For example, a government may choose to build more schools instead of more hospitals. A family might decide to buy a new game console rather than go on holiday. These everyday examples show that scarcity forces us to prioritise.
因为稀缺性的存在，我们必须做出选择。例如，政府可能选择建更多学校而不是更多医院；一个家庭可能决定买一台新游戏机而不去度假。这些日常例子说明，稀缺性迫使我们确定优先次序。
3. Needs vs Wants: Making Choices | 需要与想要：做出选择
A need is something essential for survival, such as food, water, shelter, and clothing. A want is something that makes life more comfortable or enjoyable but is not necessary to live, like a smartphone, a cinema ticket, or a fashionable pair of trainers.
需要是生存所必需的东西，比如食物、水、住所和衣服。想要则是让生活更舒适或更有趣、但并非生存必需的东西，例如智能手机、电影票或一双时髦的运动鞋。
Economists use the distinction between needs and wants to analyse consumer behaviour. Even though we know the difference, our wants often feel like needs. Learning to separate them is an important skill, especially when creating a personal budget.
经济学家利用需要和想要之间的区别来分析消费者行为。即使我们知道两者的差异，我们的想要往往感觉就像需要。学会区分它们是一项重要技能，尤其是在制定个人预算的时候。
4. Opportunity Cost: What You Give Up | 机会成本：你放弃了什么
Opportunity cost is the value of the next best alternative that you give up when making a choice. It is not simply the money spent, but the benefit you lose from the option you did not choose. Every decision has an opportunity cost.
机会成本是指当你做出一个选择时，所放弃的次优选项的价值。它不仅仅是你花掉的钱，还包括你从未选择的那个选项中失去的好处。每一个决策都有机会成本。
For instance, if you choose to spend an hour playing video games, your opportunity cost might be the higher mark you could have achieved by studying during that hour. Understanding opportunity cost helps you weigh your options more carefully.
例如，如果你选择花一小时玩电子游戏，你的机会成本可能是你用这一小时学习所能获得的更高分数。理解机会成本能帮助你更仔细地权衡各种选项。
5. Factors of Production: Resources We Use | 生产要素：我们使用的资源
To produce goods and services, we need four categories of resources, known as the factors of production: land, labour, capital, and enterprise. Land includes all natural resources. Labour refers to the human effort, both physical and mental. Capital means man-made tools and machinery, and enterprise is the ability to combine the other three factors to create a business.
要生产商品和服务，我们需要四类资源，即生产要素：土地、劳动、资本和企业家才能。土地包括所有自然资源。劳动指人类的体力和脑力付出。资本指人造的工具和机器，而企业家才能是结合其它三种要素来创办企业的能力。
In Year 7, you will often think about how your school uses factors of production: the school building (land), teachers (labour), computers and whiteboards (capital), and the headteacher’s vision (enterprise). Recognising these factors makes the economy visible all around you.
在七年级，你会经常思考学校如何运用生产要素：教学楼（土地）、教师（劳动）、电脑和白板（资本），以及校长的愿景（企业家才能）。认识到这些要素会让你看到身边处处都是经济。
6. The Three Basic Economic Questions | 三个基本经济问题
Because of scarcity, every society must answer three fundamental questions: What to produce? How to produce? And for whom to produce? These questions help determine the type of economic system a country adopts.
由于稀缺性，每个社会都必须回答三个基本问题：生产什么？如何生产？为谁生产？这些问题的答案决定了一个国家采用的经济体制类型。
In a market economy, consumers and producers answer these questions through their choices. In a planned economy, the government takes a larger role. Most countries, including the UK, have mixed economies that blend both approaches, and you will explore these differences in Year 7.
在市场经济中，消费者和生产者通过他们的选择来回答这些问题。在计划经济中，政府扮演着更重要的角色。大多数国家，包括英国，采用混合经济，融合了两种方式，你将在七年级探讨这些差异。
7. Supply and Demand: The Market Forces | 供给与需求：市场力量
Demand refers to the quantity of a good or service that consumers are willing and able to buy at various prices. Supply is the quantity that producers are willing and able to sell. Together, they determine the market price and quantity traded.
需求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。供给是生产者愿意并且能够出售的数量。两者共同决定市场价格和交易数量。
When you see a price drop during a sale, demand usually rises. If a new video game console is released and supply is limited, prices can go up. These interactions form the heartbeat of a market economy, and you will model them using simple graphs later in the course.
当你看到促销降价时，需求通常会上升。如果一款新的游戏机发布且供应有限，价格就会上涨。这些互动构成了市场经济的核心脉搏，你将在后续课程中用简单的图表来模拟它们。
8. Price Mechanism: How Prices Are Determined | 价格机制：价格如何决定
The price mechanism describes how the forces of supply and demand interact to set market prices. When demand exceeds supply, a shortage occurs, pushing prices up. When supply exceeds demand, a surplus leads to falling prices.
价格机制描述了供给与需求如何相互作用来确定市场价格。当需求超过供给时，出现短缺，推动价格上涨；当供给超过需求时，出现过剩，导致价格下跌。
This balancing process is sometimes called the invisible hand, a concept introduced by the economist Adam Smith. In a free market, prices act as signals: high prices encourage producers to make more, while low prices attract more buyers. Understanding this mechanism helps you predict how events like a drought or a new fashion trend affect prices.
这个平衡过程有时被称为“看不见的手”，由经济学家亚当·斯密提出。在自由市场里，价格充当信号：高价鼓励生产者多生产，低价吸引更多买家。理解这一机制有助于你预测干旱或新时尚潮流等事件如何影响价格。
9. Money and Its Functions | 金钱及其功能
Money is anything that is generally accepted as a medium of exchange. Its main functions are: a medium of exchange, a unit of account, a store of value, and sometimes a standard of deferred payment. Without money, we would have to rely on barter, which is inefficient.
金钱是被普遍接受的交换媒介。其主要功能包括：交换媒介、计价单位、价值贮存手段，有时也作为延期支付的标准。如果没有金钱，我们将不得不依赖以物易物，而这种方式效率低下。
In the modern economy, money takes many forms, from coins and banknotes to digital balances in your bank account. Even in Year 7, when you use online banking or contactless payment, you are witnessing the evolution of money and its ability to make transactions smoother.
在现代经济中，货币有许多形式，从硬币和纸币到银行账户里的数字余额。即使在七年级，当你使用网上银行或非接触式支付时，你就在见证货币的演变以及它如何让交易变得更顺畅。
10. Budgeting and Saving: Personal Economics | 预算与储蓄：个人经济学
A budget is a plan for how to spend and save your income. Learning to budget is one of the most practical economics skills you can develop. It involves listing your income (such as pocket money or gifts) and your expenses (snacks, entertainment, mobile credit) to ensure you do not spend more than you have.
预算是关于如何支出和储蓄收入的计划。学会编制预算是你能培养的最实用的经济学技能之一。它涉及列出你的收入（如零花钱或礼物）和支出（零食、娱乐、话费），以确保花费不超过拥有。
Saving means setting aside a portion of your income for future use. Economists talk about the trade-off between consumption now and consumption later. By saving for a larger goal, like a new bicycle, you are applying the concept of opportunity cost and delayed gratification in your daily life.
储蓄意味着将收入的一部分留作将来使用。经济学家会讨论当前消费与未来消费之间的权衡。通过为一个大目标储蓄，比如一辆新自行车，你就在日常生活中运用机会成本和延迟满足的概念。
11. Introduction to Markets: Types of Goods | 市场介绍：商品类型
Markets are places – physical or virtual – where buyers and sellers exchange goods and services. Goods can be classified in many ways. Free goods, like sunlight, are unlimited in supply. Economic goods are scarce and command a price. Consumer goods are used by individuals, while capital goods are used to produce other goods.
市场是买卖双方交换商品和服务的地方，可以是实体的或虚拟的。商品有多种分类方式。免费物品如阳光，供应无限。经济物品是稀缺的，需要付出价格。消费品由个人使用，而资本品用于生产其它商品。
Public goods, such as street lighting and national defence, are provided by the government because private businesses might not supply them adequately. Understanding these categories helps you see how goods differ in terms of who provides them and who benefits.
公共品，比如路灯和国防，是由政府提供的，因为私营企业可能无法充分供应。理解这些分类能帮助你看出商品在由谁提供、谁受益方面有何不同。
12. Preparing for Year 7 Economics: Tips for Success | 为七年级经济学做准备：成功秘诀
To start confidently, read or watch the news with an economic lens. Try to identify an opportunity cost or a change in supply and demand in a story. Keeping a vocabulary journal of new terms like ‘scarcity’, ‘enterprise’ and ‘inflation’ will reinforce your understanding.
为了自信地开始，试着用经济学的眼光阅读或观看新闻。尝试在一个故事中找出机会成本或供需的变化。准备一本词汇本，记下像“稀缺性”、“企业家才能”和“通货膨胀”这类新术语，会巩固你的理解。
Discuss everyday choices with your family. Ask why a particular cereal is cheaper, or what factors might make a cinema ticket price rise. These conversations make economics come alive. Finally, remember that economics is about people, not just numbers – your curiosity is the best tool for success.
和家人讨论日常选择。问问为什么某款麦片更便宜，或者什么因素可能导致电影票涨价。这些对话让经济学变得鲜活。最后，记住经济学关乎人，而不仅仅是数字——你的好奇心是成功的最佳工具。
