📚 Year 7 Cambridge Economics Parent’s Guide | Year 7 剑桥经济家长辅导指南
Economics is not just about money – it is the study of how people make choices when resources are limited. In Year 7, your child begins exploring this fascinating subject through the Cambridge Lower Secondary framework. This guide will help you understand what they are learning and how you can support them at home, even if you never studied economics yourself.
经济学不仅仅是关于金钱——它研究的是人们在资源有限的情况下如何做出选择。在 Year 7，您的孩子将开始通过剑桥 Lower Secondary 课程框架探索这门引人入胜的学科。本指南将帮助您了解他们的学习内容，以及如何在家中为他们提供支持，即使您自己从未学过经济学。
1. What is Economics? | 什么是经济学？
Economics is the social science that examines how individuals, businesses, and governments allocate scarce resources to satisfy unlimited wants. At Year 7 level, the focus is on introducing the fundamental economic problem: we cannot have everything we desire because resources are finite.
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以满足无限的需求。在 Year 7 阶段，重点是介绍基本的经济学问题：由于资源是有限的，我们无法拥有想要的一切。
As a parent, you can reinforce this idea through everyday examples. When your child asks for a new game and a new football, discuss how the family budget requires trade-offs. This makes the concept tangible and relevant.
作为家长，您可以通过日常例子来强化这一理念。当孩子既想要新游戏又想要新足球时，和他讨论家庭预算如何要求做出权衡。这会让概念变得具体而切合实际。
2. Core Concepts: Scarcity and Choice | 核心概念：稀缺性与选择
Scarcity is the condition in which human wants exceed the available resources. Choice is the act of selecting among alternatives. In Year 7, students learn that scarcity forces everyone – from individuals to nations – to make choices about what to produce, how to produce it, and for whom to produce it.
稀缺性是指人类的需求超过现有资源的状态。选择则是在多个选项中进行挑选的行为。在 Year 7，学生们将学习到，稀缺性迫使每个人——从个人到国家——要在生产什么、如何生产以及为谁生产之间做出选择。
Help your child see scarcity in action. When you plan a weekly meal, explain how you prioritise certain foods within a set budget. Ask them to think about a farmer who must decide between growing wheat or corn on limited land. Simple scenarios build lasting understanding.
帮助孩子观察实际的稀缺性。当您计划每周的餐食时，解释您如何在既定预算内优先安排某些食物。请他们思考一个农民必须在有限的土地上决定种小麦还是玉米。简单的场景能建立持久的理解。
3. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative forgone when a choice is made. It is not merely the cost in money but what is sacrificed. For a student, the opportunity cost of one hour spent playing video games might be the revision time lost for a test.
机会成本是做出选择时所放弃的次优选项的价值。它不仅仅是金钱成本，而是所牺牲的东西。对于学生来说，花一小时玩电子游戏的机会成本可能是为了考试而损失的复习时间。
You can practise this concept by asking ‘What did you give up?’ whenever your child makes a choice. For instance, if they spend their pocket money on sweets, the opportunity cost could be the book they planned to buy. Keep it lighthearted but consistent.
您可以在孩子每次做出选择时问“你放弃了什么？”来练习这个概念。例如，如果他们用零花钱买了糖果，机会成本可能就是他们本来打算买的那本书。要保持轻松但坚持提问。
4. Demand and Supply | 需求与供给
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. Year 7 students are introduced to the basic shape of demand and supply curves and how they interact to determine market prices.
需求是指消费者在不同价格水平上愿意且能够购买的商品或服务的数量。供给则是生产者愿意且能够出售的数量。Year 7 学生会被介绍需求曲线和供给曲线的基本形状，以及它们如何相互作用决定市场价格。
Use simple market examples like a lemonade stand. Ask your child what happens to the quantity of lemonade demanded if you raise the price on a hot day. Or what happens to supply if the cost of lemons increases. Such thought experiments build economic intuition.
使用简单的市场例子，比如柠檬水小摊。问孩子，如果在炎热的天气里提高价格，柠檬水的需求量会怎样。或者如果柠檬的成本增加，供给量会怎样。这样的思维实验能培养经济学直觉。
5. Markets and Prices | 市场与价格
A market is any arrangement that allows buyers and sellers to exchange goods or services. Prices act as signals that coordinate the decisions of producers and consumers. In Year 7, students explore how prices adjust when demand or supply changes, moving towards an equilibrium where quantity demanded equals quantity supplied.
市场是允许买方和卖方交换商品或服务的任何安排。价格则充当协调生产者和消费者决策的信号。在 Year 7，学生将探索当需求或供给发生变化时，价格如何调整，趋向于需求量等于供给量的均衡点。
You can discuss real-world price changes in a simple way. When strawberries are plentiful in summer and prices fall, explain that supply has increased. When concert tickets sell out quickly, demand is high relative to supply. These everyday observations reinforce classroom learning.
您可以以简单的方式讨论现实世界中的价格变动。当夏天草莓供应充足、价格下降时，解释那是供给增加了。当音乐会门票迅速售罄时，说明需求相对于供给较高。这些日常观察能巩固课堂学习。
6. Production and Producers | 生产与生产者
Production is the process of turning inputs (land, labour, capital, and enterprise) into outputs of goods and services. Producers decide what to produce, how to produce it efficiently, and how to minimise costs. Year 7 introduces the factors of production in a straightforward way, often through case studies of local businesses.
生产是将投入（土地、劳动、资本和企业家才能）转化为商品和服务产出的过程。生产者决定生产什么、如何高效生产以及如何最小化成本。Year 7 以简单明了的方式介绍生产要素，通常通过本地企业的案例研究来进行。
At home, you can talk about the production of a favourite snack. What ingredients are needed (land)? Who bakes it (labour)? What equipment is used (capital)? Who organised the whole process (enterprise)? Breaking down products into factors of production makes economics tangible.
在家中，您可以谈论一种最喜爱零食的生产过程。需要哪些配料（土地）？谁烘烤它（劳动）？使用了什么设备（资本）？谁组织了整个过程（企业家才能）？将产品分解为生产要素使经济学变得具体可感。
7. Consumption and Consumers | 消费与消费者
Consumption is the use of goods and services to satisfy wants. Consumers make purchasing decisions based on factors such as income, preferences, and prices. Year 7 students learn that all people are consumers, and their spending patterns affect what businesses decide to produce.
消费是使用商品和服务来满足需求的过程。消费者根据收入、偏好和价格等因素做出购买决策。Year 7 学生学习到每个人都是消费者，他们的消费模式会影响企业决定生产什么。
Encourage your child to track their own spending for a week. Ask them to categorise items into ‘needs’ and ‘wants’. Discuss how advertisements might influence their choices, and how a limited budget forces careful consumption decisions. This personal finance angle is highly engaging.
鼓励孩子记录一周的支出。请他们将物品分类为“必需品”和“想要的东西”。讨论广告如何影响他们的选择，以及有限的预算如何迫使人们做出谨慎的消费决策。这个个人理财的角度非常吸引人。
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. Before money, barter systems required a double coincidence of wants, which was highly inefficient. Year 7 introduces the evolution of money and how it facilitates trade in modern economies.
货币有三个主要功能：交易媒介、计价单位和价值储藏手段。在货币出现之前，物物交换制度需要双方需求的巧合匹配，效率极低。Year 7 介绍了货币的演变，以及货币如何促进现代经济中的贸易。
You can bring this to life by trying a small barter experiment at home. Have your child trade a toy for a snack without using money. The difficulties they encounter will vividly illustrate why money is so useful. Then discuss how digital payments like mobile wallets relate to the concept of money.
您可以在家中尝试一个小型物物交换实验，让这个概念生动起来。让孩子在不使用钱的情况下用玩具交换零食。他们遇到的困难将生动地说明为什么货币如此有用。然后讨论移动钱包等数字支付如何与货币概念相关联。
9. Economic Systems | 经济体系
Different societies organise their economies in different ways. Year 7 students explore the basic spectrum from free market economies, where private individuals and firms make most decisions, to command economies, where the government decides what to produce and how to allocate resources. Most real economies are mixed economies.
不同的社会以不同的方式组织其经济。Year 7 学生们探索从自由市场经济（私人和企业做出大多数决策）到指令经济（政府决定生产什么和如何分配资源）的基本谱系。大多数现实经济是混合经济。
Relate this to current events. If there is news about government subsidies for farmers or public healthcare, explain that these are elements of a mixed economy. Ask your child what they think would happen if everything were free – linking back to scarcity and choice.
联系当前事件。如果有关于政府为农民提供补贴或公共医疗的新闻，解释这些是混合经济的要素。问孩子如果一切都是免费的，会发生什么——这又回到了稀缺性和选择的主题。
10. How to Support Your Child’s Learning | 如何支持孩子的学习
Supporting your child in Year 7 economics does not require expert knowledge. Create a curious environment by discussing economic news in an age-appropriate way. Encourage questions like ‘Why do some brands cost more?’ or ‘How do shops decide what to sell?’ These conversations build economic literacy.
支持孩子在 Year 7 的经济学学习不需要专业知识。通过以适合年龄的方式讨论经济新闻来营造一个好奇的环境。鼓励他们提问，比如“为什么有些品牌更贵？”或“商店如何决定卖什么？”这些对话能培养经济素养。
Utilise Cambridge-endorsed resources such as the learner’s book and workbook. Set aside a regular time for reviewing key terms together. You can also play simple board games involving trade and strategy, like Monopoly, and discuss the economic decisions made during the game. Real-world trips to a supermarket can turn into lessons on pricing, budgeting, and consumer choice.
使用剑桥推荐的资源，如学生用书和练习册。安排固定时间一起复习关键词汇。您也可以玩一些涉及贸易和策略的简单桌游，如《大富翁》，并讨论游戏中做出的经济决策。去超市的实地考察可以变成关于定价、预算和消费者选择的课程。
