1. What is Economics? | 什么是经济学？

Economics is the study of how people make choices to satisfy their needs and wants when resources are limited. It helps us understand why we cannot have everything we desire and how societies decide what to produce, how to produce it, and for whom to produce it. At the Year 7 level, your child will explore basic economic questions and see how economics affects everyday life.

经济学研究的是人们在资源有限的情况下如何做出选择以满足自己的需要和欲望。它帮助我们理解为什么不能拥有所有想要的东西，以及社会如何决定生产什么、如何生产以及为谁生产。在七年级阶段，您的孩子将探索基本的经济问题，并了解经济学如何影响日常生活。

For example, a family may have to choose between buying a new game console or saving for a holiday. Both are wants, but limited income forces a decision. Economics provides a framework to analyse such choices and their consequences.

例如，一个家庭可能不得不在购买新游戏机或为度假存钱之间做出选择。两者都是欲望，但有限的收入迫使家庭做出决定。经济学提供了分析这类选择及其后果的框架。

2. Scarcity and Choice | 稀缺性与选择

Scarcity is the fundamental economic problem. It exists because there are unlimited wants but only limited resources to fulfil them. Because of scarcity, individuals, businesses, and governments must constantly make choices. Understanding scarcity helps young learners appreciate why they cannot get everything they ask for and why prioritising is essential.

稀缺性是经济学的根本问题。它之所以存在，是因为人类的欲望无限，但满足这些欲望的资源却有限。由于稀缺性，个人、企业和政府必须不断做出选择。理解稀缺性有助于青少年学习者明白为什么他们不能得到所有想要的东西，以及为什么分清轻重缓急至关重要。

A simple way to explain scarcity to your child is to use the example of time. There are only 24 hours in a day. If your child spends two hours on video games, they have two hours less for homework or sports. This trade-off illustrates the concept of choice under scarcity.

向孩子解释稀缺性的一个简单方法是利用时间的例子。一天只有24小时。如果孩子花了两个小时玩电子游戏，那么用于做作业或运动的时间就少了两个小时。这种取舍就是稀缺性下的选择。

Resources are limited, wants are unlimited. | 资源有限，欲望无限。
Every choice involves giving up something else. | 每个选择都意味着放弃其他东西。

3. Opportunity Cost | 机会成本

Opportunity cost is the value of the next best alternative that is given up when a choice is made. It is not just about money; it includes time, enjoyment, and other benefits lost. In Year 7, students learn to identify opportunity costs in everyday decisions, which helps them think more critically about their options.

机会成本是指做出某个选择时所放弃的次优替代选项的价值。它不仅涉及金钱，还包括时间、乐趣和其他损失的利益。七年级学生学习在日常生活中识别机会成本，这有助于他们更批判性地思考各种选项。

If your child decides to buy a comic book instead of a snack, the opportunity cost is the snack they didn’t buy. If they spend Saturday morning revising economics, the opportunity cost might be the fun they could have had playing football. Encouraging your child to ask ‘What am I giving up?’ builds a strong economic mindset.

如果您的孩子决定买一本漫画书而不是买零食，机会成本就是他们没有买的零食。如果他们周六上午复习经济学，机会成本可能就是本可以踢足球的乐趣。鼓励孩子问“我放弃了什么？”可以培养稳固的经济思维。

4. Factors of Production | 生产要素

To produce goods and services, four factors of production are needed: land, labour, capital, and enterprise. Land includes all natural resources. Labour refers to human effort. Capital is man-made tools and machinery used in production. Enterprise is the ability to combine the other factors and take risks to start a business.

要生产商品和服务，需要四种生产要素：土地、劳动、资本和企业精神。土地包括所有自然资源。劳动指人的努力。资本是用于生产的人造工具和机械。企业精神则是整合其他要素并承担风险来创业的能力。

Factor	Example for Year 7
Land	Forests, oil, a farm
Labour	Teacher, cashier, builder
Capital	Computers, factory machines, delivery vans
Enterprise	The person who starts a new bakery

At home, you might discuss what factors went into making a simple product like a pencil: wood (land), workers (labour), factory equipment (capital), and the entrepreneur who organised the process (enterprise).

在家可以一起讨论制造一个简单产品（如铅笔）需要哪些要素：木材（土地）、工人（劳动）、工厂设备（资本）以及组织整个过程的企业家（企业精神）。

5. 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 sell. The law of demand states that, all else equal, as price falls, quantity demanded increases. The law of supply states that as price rises, quantity supplied increases.

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。供给是指生产者在不同价格下愿意并且能够出售的数量。需求定律指出，在其他条件不变时，价格下降，需求量增加。供给定律则指出，价格上升，供给量增加。

A relatable example is a school tuck shop. If the price of pizza slices drops, more students will want to buy them (demand increases). If the tuck shop can sell pizza at a higher price, they will be willing to supply more. Discussing small, observable markets around your child makes the theory come alive.

一个容易理解的例子是学校小卖部。如果比萨饼的价格下降，会有更多学生想买（需求增加）。如果小卖部能以更高价格出售比萨饼，他们就愿意供应更多。和孩子讨论身边容易观察的小市场，能让理论变得鲜活。

6. Market Equilibrium | 市场均衡

Market equilibrium occurs where the quantity demanded equals the quantity supplied. At this point, the price is stable and there is no shortage or surplus. If the price is above equilibrium, a surplus emerges; if below, a shortage occurs. Year 7 students begin to see how prices act as signals to coordinate buyers and sellers.

市场均衡发生在需求量与供给量相等之时。此时价格稳定，没有短缺或过剩。若价格高于均衡，则出现过剩；低于均衡，则出现短缺。七年级学生开始认识到价格如何作为信号协调买卖双方。

Imagine a popular new video game. If the price is set too high, some copies remain unsold (surplus). The shop may reduce the price. If priced too low, the game sells out quickly (shortage) and the shop might raise the price. Over time, the price tends to settle where demand meets supply.

想象一款热门的新电子游戏。如果定价过高，有些游戏盘将卖不出去（过剩），商店可能会降价。如果定价过低，游戏很快售罄（短缺），商店可能提价。久而久之，价格倾向于在需求与供给相遇处稳定下来。

7. 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. Before money, people used barter, which required a double coincidence of wants. Money makes trading much easier and more efficient. Your child will explore the history and functions of money at a basic level.

货币主要有三个功能：交易媒介、计价单位和价值储藏。在货币出现之前，人们进行物物交换，这需要双方需求的巧合。货币让交易变得更加容易和高效。您的孩子将初步探索货币的历史和功能。

Ask your child why we don’t pay for lunch with a chicken. That leads to a discussion on the inconvenience of barter and the benefits of a common currency. Also, you can talk about how money lets us save today’s income for future spending, illustrating the store of value.

问问你的孩子，我们为什么不用一只鸡来支付午餐费。这可以引出物物交换的不便和通用货币的好处的讨论。另外，还可以谈谈货币如何让我们把今天的收入存起来以备未来消费，从而说明价值储藏功能。

8. Economic Systems | 经济体系

Different societies answer the basic economic questions in different ways. The main types are market economies, where decisions are driven by private individuals and firms, and planned economies, where the government makes most decisions. Most real economies are mixed, combining elements of both. Understanding this helps students see how economic choices are organised globally.

不同的社会以不同方式回答基本的经济问题。主要类型有市场经济，即决策由私人个体和企业驱动；以及计划经济，即政府做出大多数决策。大多数现实中的经济体是混合经济，融合了两者的元素。理解这一点有助于学生看到全球经济选择是如何组织的。

Market Economy	Planned Economy
Consumers and producers decide.	Government central planning decides.
Prices guide resource allocation.	The state sets production targets.
Example: USA, UK (mostly market).	Example: North Korea (more planned).

You can encourage your child to identify which type of system is reflected in news stories about government building hospitals (planned element) or private companies launching new phones (market element). This builds real-world connections.

您可以鼓励孩子在新闻中辨别，政府建医院反映了计划元素，私人公司推出新手机反映了市场元素。这样能建立与现实世界的联系。

9. Spending, Saving and Budgeting | 消费、储蓄与预算

Personal finance is an important part of early economics. Students learn the difference between spending on immediate wants and saving for future goals. They also explore the idea of a budget: a plan for managing income and expenses. These skills lay the groundwork for responsible financial habits later in life.

个人理财是早期经济学的重要组成部分。学生学习为眼前的欲望进行消费和为未来目标进行储蓄之间的区别。他们还探索预算的概念——一个管理收支的计划。这些技能为日后养成负责任的财务习惯打下基础。

Set a simple budget challenge with your child. Give them a hypothetical weekly allowance and list some wants and needs. Let them decide how to allocate money to save for a desired item. Discuss trade-offs and the satisfaction of reaching a savings goal. This hands-on activity reinforces concepts like opportunity cost and delayed gratification.

与孩子一起设定一个简单的预算挑战。给他们一笔假设的每周零花钱，并列出一些想要的物品和必需品。让他们决定如何分配资金以存钱购买心仪的物品。讨论其中的取舍以及达成储蓄目标后的满足感。这项动手活动会强化机会成本和延迟满足等概念。
