1. Welcome to Year 7 Economics | 欢迎学习7年级经济学
Economics is not just about money – it is about making choices. In Year 7, you will explore how individuals, businesses, and governments decide what to do with limited resources. This course is designed to build your thinking skills and prepare you for more advanced study.
经济学不仅仅是关于金钱——它关乎如何做出选择。在7年级，你将探索个人、企业和政府如何决定如何使用有限的资源。这门课程旨在培养你的思维能力，为更深入的学习做好准备。
During summer, a little preparation goes a long way. By reading real-world news, discussing choices with your family, and learning key vocabulary, you will enter the classroom with confidence.
在暑假期间，稍做准备会大有裨益。通过阅读现实新闻、与家人讨论选择、学习关键词汇，你将自信地走进课堂。
2. What Is Economics? | 什么是经济学？
Economics is the study of how people use scarce resources to satisfy unlimited wants. It is split into microeconomics – looking at individuals and firms – and macroeconomics – examining whole economies. Both areas help us understand everyday life, from why prices change to why some countries are richer than others.
经济学是研究人们如何用稀缺资源满足无限欲望的学科。它分为微观经济学（关注个人和企业）和宏观经济学（审视整个经济体）。这两个领域都能帮助我们理解日常生活，从价格为何变动到为何有些国家比其他国家更富裕。
Think of economics as a toolkit for making better decisions. Whether you are choosing how to spend your pocket money or a government is planning its budget, the same principles apply.
把经济学看作一套做更好决定的工具箱。无论你是在选择如何花零用钱，还是政府在规划预算，同样的原则都适用。
3. Scarcity: The Fundamental Economic Problem | 稀缺性：根本的经济问题
Scarcity exists because resources are limited while wants are unlimited. This is the most basic concept in economics. Even wealthy countries face scarcity of time, labour, or natural resources, which forces everyone to make choices.
稀缺性之所以存在，是因为资源有限而欲望无限。这是经济学最基本的概念。即便是富裕国家也面临时间、劳动力或自然资源的稀缺，这迫使每个人都必须做出选择。
For example, a farmer has a fixed piece of land. If they choose to grow wheat, they cannot use the same land to grow rice at the same time. The land is scarce, so a choice must be made.
例如，一个农民拥有一块固定的土地。如果他选择种小麦，就不能同时用同一块地种水稻。土地是稀缺的，因此必须做出选择。
Scarcity leads to three fundamental questions: What to produce? How to produce? For whom to produce? These questions shape all economic systems.
稀缺性引出了三个基本问题：生产什么？如何生产？为谁生产？这些问题塑造了所有经济体系。
4. Opportunity Cost: The Next Best Alternative | 机会成本：次优选择
Every choice involves an opportunity cost – the value of the next best alternative you give up. It is not just about money; it can include time, enjoyment, or any benefit you miss out on when you choose one option over another.
每个选择都涉及机会成本——你所放弃的次优选择的价值。它不仅仅是金钱；当你选择一个选项而放弃另一个时，它还可能包括时间、乐趣或任何你错过的收益。
If you spend one hour studying economics, the opportunity cost might be the hour you could have spent playing football. Recognising opportunity costs helps you make more thoughtful decisions.
如果你花一小时学习经济学，机会成本可能是你本可以用来踢足球的那一小时。认识到机会成本有助于你做出更周全的决定。
In real life, governments also consider opportunity costs when allocating budgets – choosing between building a new hospital or a new road, for instance.
在现实生活中，政府在分配预算时也会考虑机会成本——例如，在建造新医院还是新道路之间做出选择。
5. Needs vs. Wants | 需要与想要
Needs are essential for survival, such as food, water, shelter, and clothing. Wants are things we desire but could live without, like the latest smartphone, video games, or luxury holidays. Understanding this difference is key to studying consumer behaviour.
需要是生存所必需的，如食物、水、住所和衣物。想要是我们渴望但并非生活必需的东西，比如最新款的智能手机、电子游戏或奢华假期。理解这一区别是研究消费者行为的关键。
Businesses try to turn wants into perceived needs through advertising. Over time, some wants can become so common that they feel like needs – consider how many people now view internet access as essential.
企业通过广告试图将想要转化为感知上的需要。随着时间的推移，一些想要可能变得如此普遍，以至于感觉像需要——想想现在有多少人将互联网接入视为必需品。
When you budget your pocket money, separating needs from wants helps you prioritise spending and saving.
当你为零用钱做预算时，区分需要和想要有助于你优先安排开支和储蓄。
6. Introduction to Demand and Supply | 需求与供给简介
Demand is the quantity of a good or service consumers are willing and able to buy at different prices. Supply is the quantity producers are willing and able to sell. These two forces interact in every market to determine prices.
需求是消费者在不同价格下愿意且能够购买的商品或服务的数量。供给是生产者愿意且能够出售的数量。这两种力量在每个市场中相互作用，决定价格。
The law of demand states that, all else equal, as price increases, quantity demanded decreases. The law of supply states that as price increases, quantity supplied increases. You can observe this in everyday life: if a new video game is very expensive, fewer people will buy it.
需求定律指出，在其他条件不变的情况下，价格上升时需求量下降。供给定律指出，价格上升时供给量增加。你可以在日常生活中观察到这一点：如果一款新电子游戏非常昂贵，购买的人就会减少。
Changes in factors like income, tastes, and the price of related goods shift the whole demand curve. Similarly, production costs and technology shift the supply curve.
收入、偏好及相关商品价格等因素的变化会使整个需求曲线移动。同样，生产成本和技术也会使供给曲线移动。
7. Markets and Prices | 市场与价格
A market is any place or system where buyers and sellers meet to exchange goods or services. This could be a physical shop, an online store, or even a stock exchange. Prices in a market economy act as signals to both consumers and producers.
市场是买卖双方聚集交换商品或服务的任何地方或系统。它可以是实体商店、网店，甚至是证券交易所。在市场经济中，价格作为信号传递给消费者和生产者。
When demand for a product rises faster than supply, prices tend to go up. This signals producers to make more of that product. When prices fall, it might indicate that consumers want less of the item or that there is too much supply.
当某产品的需求增长快于供给时，价格往往会上涨。这向生产者发出增加该产品产量的信号。当价格下跌时，可能意味着消费者对该商品的需求减少，或供给过多。
Understanding the price mechanism helps explain why the cost of seasonal fruits changes or why concert tickets can be resold at very high prices.
理解价格机制有助于解释为什么季节性水果的价格会变化，或者为什么音乐会门票能以很高的价格转售。
8. Personal Finance Basics | 个人理财基础
Personal finance in Year 7 introduces the concepts of income, spending, saving, and budgeting. You will learn how to manage your own money, whether from an allowance, a part-time job, or gifts. Creating a simple budget is a life skill.
7年级的个人理财介绍了收入、支出、储蓄和预算的概念。你将学习如何管理自己的钱，无论是零用钱、兼职工作收入还是礼物。制定一个简单的预算是一项生活技能。
Savings are important for future goals and unexpected expenses. Banks offer savings accounts that pay interest – the reward for letting the bank use your money. Compound interest can make savings grow over time.
储蓄对于未来目标和意外支出很重要。银行提供支付利息的储蓄账户——这是让银行使用你的资金的回报。复利可以使储蓄随着时间增长。
You should also distinguish between needs and wants when spending, and avoid impulse buying. Keep a record of your expenses to see where your money goes each week.
你还应该在支出时区分需要和想要，避免冲动消费。记录你的开支，了解每周钱的去向。
9. Economic Agents: Households, Firms, Government | 经济主体：家庭、企业、政府
Three main groups make decisions in an economy. Households supply labour and consume goods. Firms produce goods and services to make a profit. The government sets rules, collects taxes, and provides public services like education and healthcare.
经济体中有三个主要决策群体。家庭提供劳动并消费商品。企业生产商品和服务以获取利润。政府制定规则、征税并提供教育和医疗等公共服务。
These agents interact in the circular flow of income. Households provide factors of production (labour, land, capital) to firms and receive wages, rent, and profit in return. Spending by households becomes firms’ income, which is used to pay for resources.
这些主体在收入循环流中相互作用。家庭向企业提供生产要素（劳动、土地、资本），并获得工资、租金和利润作为回报。家庭的支出成为企业的收入，用于支付资源成本。
Government plays a vital role by redistributing income through taxes and benefits, and by funding infrastructure that helps the market function smoothly.
政府通过税收和福利进行收入再分配，并为帮助市场顺利运行的基础设施提供资金，从而发挥关键作用。
10. Production and Resources | 生产与资源
Production is the process of turning inputs (resources) into outputs (goods and services). Resources, also called factors of production, are divided into four categories: land (natural resources), labour (human effort), capital (machinery and tools), and entrepreneurship (the skill of combining the other three).
生产是将投入（资源）转化为产出（商品和服务）的过程。资源，也称为生产要素，分为四类：土地（自然资源）、劳动力（人力）、资本（机器和工具）和企业家精神（组合其他三者的技能）。
Productivity measures how efficiently we use resources. Increasing productivity means getting more output from the same input. This can be achieved through better technology, skilled workers, or improved processes.
生产率衡量我们使用资源的效率。提高生产率意味着用相同的投入获得更多的产出。这可以通过更好的技术、熟练的工人或改进的流程来实现。
Specialisation occurs when individuals or countries focus on what they are best at. This increases overall output but also creates interdependence because no one produces everything they need.
当个人或国家专注于他们最擅长的事情时，就会产生专业化。这增加了总产出，但也造成了相互依赖，因为没有人生产自己需要的一切。
11. How to Succeed in Year 7 Economics | 如何在7年级经济中取得成功
Success in Economics comes from regular practice and curiosity. Read news articles related to the economy, keep a vocabulary notebook for new terms, and try to explain concepts aloud to a friend or family member. This will deepen your understanding.
经济的成功来自定期练习和好奇心。阅读与经济相关的新闻文章，为新的术语准备词汇笔记本，并尝试向朋友或家人大声解释概念。这将加深你的理解。
Use diagrams to visualise relationships, such as a basic demand and supply graph. Even simple drawings can help you remember how markets work. Ask your teacher questions whenever something is unclear.
使用图表来可视化关系，比如基本的供需图。即使是简单的绘图也有助于你记住市场如何运作。每当有不清楚的地方，向老师提问。
Practise past exam questions under timed conditions. Edexcel tests often include multiple-choice and short-answer questions. Understanding command words like ‘define’, ‘explain’, and ‘analyse’ is essential.
在限时条件下练习过去的考题。Edexcel的考试通常包括选择题和简答题。理解像“定义”、“解释”和“分析”这样的指令词至关重要。
12. Final Tips for a Smooth Transition | 平稳过渡的最后建议
Transitioning into secondary school Economics is easier when you link theory to real life. Over the summer, keep a simple ‘economics diary’ where you note one economic decision you make each day, such as choosing a snack or saving your money.
当你将理论与现实生活联系起来时，过渡到中学经济会更容易。在暑假期间，写一本简单的“经济学日记”，每天记录自己做出的一个经济决定，比如选择零食或储蓄。
Stay organised by familiarising yourself with the Edexcel specification for Year 7. The key areas are basic microeconomics, personal finance, and the role of economic agents. Don’t try to learn everything at once – a little each day builds good habits.
通过熟悉Edexcel 7年级的课程大纲来保持条理。关键领域包括基础微观经济学、个人理财以及经济主体的角色。不要试图一次学完所有内容——每天学一点可以养成好习惯。
Finally, remember that Economics is about people and choices. Ask ‘why?’ and ‘what if?’ regularly, and you will naturally develop an economist’s mindset before the first day of school.
最后，记住经济学是关于人与选择的。经常问“为什么？”和“如果……会怎样？”，你就会在开学前自然而然地培养出经济学家的思维方式。
