1. What Is Economics and Why Study It? | 什么是经济学？为什么要学习它？
Economics is the study of how people make choices when they have limited resources. Every day, individuals, businesses and governments face decisions about what to produce, how to produce it and who gets to consume the goods and services. Understanding economics helps you see the world as a set of trade‑offs and teaches you to think logically about everyday problems. For Year 7 learners, it connects directly to topics like pocket money, shopping decisions and even why some toys are more expensive than others.
经济学研究的是人们在资源有限的情况下如何做出选择。个人、企业和政府每天都要面对生产什么、如何生产以及由谁来消费商品和服务的决策。理解经济学能帮助你用权衡的眼光看待世界，并教会你对日常问题进行逻辑思考。对于七年级学生来说，这门学科与零用钱、购物决定，甚至为何某些玩具比其他玩具更贵等话题直接相连。
- Key idea: Economics is about choice under scarcity. / 核心理念：经济学是在稀缺条件下的选择。
- Relevance: It explains everyday decisions and helps you plan better. / 关联性：它能解释日常决策，帮助你更好地规划。
2. Scarcity and the Economic Problem | 稀缺性与经济问题
Scarcity means that there are not enough resources to satisfy all human wants. Because we cannot have everything we desire, we must make choices. This is known as the basic economic problem. Even in a wealthy family, time is scarce – you cannot be in two places at once. In a country, natural resources, workers and machinery are limited, so society must decide what to produce first. Recognising scarcity is the first step to thinking like an economist.
稀缺性意味着没有足够的资源来满足人类所有的欲望。因为我们不能拥有想要的一切，就必须做出选择，这就是基本经济问题。即使在一个富裕的家庭中，时间也是稀缺的——你不可能同时身处两地。在一个国家里，自然资源、劳动力和机器设备都是有限的，因此社会必须决定优先生产什么。认识到稀缺性，是像经济学家一样思考的第一步。
Example: Your Saturday afternoon – you can either play football or watch a film, but not both at the same time. The scarcity of time forces a choice. / 例子：周六下午——你可以踢足球或看电影，但不能同时进行。时间的稀缺迫使你做出选择。
3. Opportunity Cost – The Next Best Alternative | 机会成本——次优选择
Whenever you make a choice, you give up the next best alternative. That sacrifice is called opportunity cost. It is not just about money – it includes time, enjoyment and other benefits. If a student decides to spend an extra hour revising economics instead of playing video games, the opportunity cost is the enjoyment and relaxation the gaming would have provided. Thinking about opportunity cost helps you make more thoughtful decisions because you consider what you are actually giving up.
每当你做出一个选择时，你都会放弃次优的那个选项。这种牺牲就称为机会成本。机会成本不仅与金钱有关，还包括时间、乐趣和其他收益。如果一名学生决定额外花一小时复习经济而不是玩电子游戏，那么机会成本就是游戏所能带来的快乐和放松。考虑机会成本有助于你做出更周到的决定，因为你会认真思考自己真正放弃了什么。
Opportunity Cost = Value of the Next Best Alternative Given Up
机会成本 = 所放弃的次优选项的价值
4. Factors of Production – How We Make Things | 生产要素——我们如何生产物品
Goods and services are created by combining four factors of production: land, labour, capital and enterprise. Land includes all natural resources such as water, forests and minerals. Labour is the human effort, both physical and mental. Capital refers to man‑made tools, machinery and buildings used in production. Enterprise is the skill of bringing the other three factors together to start a business, taking risks in the hope of earning a profit. Understanding these factors helps you see exactly what goes into every product you use.
商品和服务是通过组合四种生产要素创造出来的：土地、劳动、资本和企业家才能。土地包括所有自然资源，如水源、森林和矿产。劳动是人类的体力和脑力付出。资本指生产中使用的工具、机器和建筑物等人造资源。企业家才能则是将其他三种要素结合起来创业的技能，并承担风险以获取利润。理解这些要素能让你看清，你使用的每一件产品背后都投入了哪些资源。
| Factor 要素 | Meaning 含义 | Example 例子 |
|---|---|---|
| Land 土地 | Natural resources 自然资源 | Oil, fish, farmland 石油、鱼、农田 |
| Labour 劳动 | Human effort 人力 | Teacher, builder 教师、建筑工人 |
| Capital 资本 | Man‑made aids 人造辅助工具 | Tractor, computer 拖拉机、电脑 |
| Enterprise 企业家才能 | Risk‑taking & organisation 承担风险与组织 | Business founder 企业创始人 |
5. Demand and Supply – The Forces of the Market | 需求与供给——市场的力量
Demand shows how much of a product consumers are willing and able to buy at different prices. Generally, when the price falls, people demand more – this is the law of demand. Supply shows how much producers are willing to offer for sale. Usually, when the price rises, suppliers are willing to produce more because they can earn higher profits. These two forces interact in a market to determine both the price and the quantity sold.
需求表示消费者在不同价格下愿意并且能够购买的产品数量。一般来说，价格下降时，人们的需求量会增加——这就是需求定律。供给表示生产者愿意出售的数量。通常当价格上升时，供给者愿意生产更多，因为可以赚取更高的利润。这两种力量在市场中相互作用，共同决定商品的价格和销售量。
Quick check: If a new video game is priced at £60, fewer people may buy it than if it were £30. The lower price increases the quantity demanded. / 快速检测：如果一款新电子游戏定价60英镑，购买的人可能比定价30英镑时少。较低的价格会增加需求量。
6. Market Equilibrium and Prices | 市场均衡与价格
Market equilibrium occurs at the price where the quantity demanded equals the quantity supplied. At this point, there is no surplus (too much supply) and no shortage (too much demand). Prices act as signals: if a shortage appears, prices tend to rise, encouraging producers to supply more. If there is a surplus, prices fall, encouraging consumers to buy more. Understanding equilibrium helps explain why shop prices change over time and why sales happen.
市场均衡出现在需求量等于供给量的价格水平上。此时没有过剩（供给太多），也没有短缺（需求太多）。价格起到信号作用：如果出现短缺，价格往往会上升，激励生产者增加供给；如果出现过剩，价格会下降，鼓励消费者多购买。理解均衡有助于解释为什么商店里的价格会随时间变化，以及为什么会有促销活动。
Equilibrium: Quantity Demanded = Quantity Supplied
均衡：需求量 = 供给量
7. Money and Exchange | 货币与交易
Money is anything widely accepted as a means of payment. It serves three main functions: a medium of exchange (we use it to buy goods), a unit of account (we measure value in pounds and pence) and a store of value (we can save it for future use). Before money, people used barter – exchanging one good for another directly – which was very inconvenient. Modern economies rely on money to make trade smooth and efficient. In Year 7 Economics, you are also expected to understand the difference between cash and digital payments.
货币是被广泛接受用作支付手段的任何东西。它有三大功能：交易媒介（我们用货币购买商品）、计价单位（我们用英镑和便士衡量价值）和价值储藏（可以储存起来供将来使用）。在货币出现之前，人们使用物物交换——直接用一种商品交换另一种——这非常不方便。现代经济依赖货币，让贸易顺畅高效。在七年级经济课程中，你也需要了解现金支付与数字支付的区别。
| Function 功能 | Explanation 说明 |
|---|---|
| Medium of exchange 交易媒介 | Accepted for buying goods and services 用于购买商品和服务 |
| Unit of account 计价单位 | A common measure to state prices 表示价格的统一度量 |
| Store of value 价值储藏 | Can be saved and used later 可以储存起来将来使用 |
8. Personal Finance: Saving and Budgeting | 个人理财：储蓄与预算
Learning to manage money is a crucial skill in everyday economics. A budget is a plan that shows how much money you receive and how you intend to spend it over a certain period. By creating a simple budget, you can make sure your spending does not exceed your income. Saving means setting aside part of your income for future needs or wants. Even young learners can practise budgeting by planning their weekly pocket money, deciding how much to spend, how much to save and whether to donate a small amount. Good habits formed now will help you make wiser financial decisions throughout your life.
学会管理金钱是日常经济中的一项关键技能。预算是一份显示你在某段时间内收入以及打算如何支出的计划。通过编制简单的预算，你可以确保支出不超过收入。储蓄意味着将一部分收入存起来，以备将来之需或购买想要的物品。即使是年轻的学习者，也可以通过规划每周的零用钱来练习做预算，决定花多少、存多少，以及是否捐出一小部分。现在养成的好习惯将帮助你在未来做出更明智的财务决策。
Tip: Use the 50‑30‑20 rule as a guide – 50% for needs, 30% for wants and 20% for savings. / 提示：可用 50‑30‑20 法则作为指导——50% 用于必需品，30% 用于想要的东西，20% 存入储蓄。
9. Types of Economic Systems – A Brief Look | 经济系统类型概览
Different countries organise their economies in different ways. The three main types are market economy, where decisions are made by individuals and firms based on price signals; command economy, where the government makes most economic decisions; and mixed economy, which combines elements of both. Most real‑world economies, including the UK, are mixed. Year 7 students are expected to recognise that no economy is purely one type and to understand the basic role of the government in providing services like schools and healthcare that the market might not supply fairly.
不同国家以不同的方式组织其经济。三种主要类型是：市场经济，由个人和企业根据价格信号做出决策；计划经济，由政府做出大部分经济决策；混合经济，融合了前两者的要素。包括英国在内的大多数现实经济体都属于混合经济。七年级学生需要认识到，没有哪个经济体纯粹属于一种类型，并理解政府的基本作用——提供市场可能无法公平供给的服务，如学校和医疗保健。
- Market economy: consumer choice drives production. / 市场经济：消费者选择驱动生产。
- Command economy: government planning controls resources. / 计划经济：政府计划控制资源。
- Mixed economy: both private sector and government share responsibility. / 混合经济：私营部门和政府共同承担责任。
10. Your Two‑Week Winter Revision Timetable | 你的寒假两周复习时间表
To make the most of the winter break, follow this daily plan for ten study sessions. Each session lasts about 45 minutes and focuses on one key topic. On the remaining days, allow yourself to rest or review weak areas. Keep a notebook where you write key terms in both English and Chinese and draw simple diagrams for supply and demand. Active recall – closing your book and explaining a concept aloud – is far more effective than simply re‑reading notes. By the end of Day 10, you will have covered all the core Year 7 SQA Economics topics systematically.
为了充分利用寒假，请按照以下每日计划进行十个学习时段。每个时段大约45分钟，聚焦一个关键主题。其余的日子则可以休息或复习薄弱环节。准备一本笔记本，用中英文写下关键术语，并画简单的供求示意图。主动回忆——合上书大声解释一个概念——远比单纯重读笔记有效得多。到第10天结束时，你将系统地完成所有七年级 SQA 经济核心主题的复习。
| Day 天 | Topic 主题 | Task 任务 |
|---|---|---|
| 1 | Scarcity and choice 稀缺与选择 | Define scarcity, list 3 everyday examples 定义稀缺，列出3个日常例子 |
| 2 | Opportunity cost 机会成本 | Calculate opportunity cost of 2 personal decisions 计算2项个人决策的机会成本 |
| 3 | Factors of production 生产要素 | Draw a diagram linking factors to a chocolate bar 画出巧克力棒与各要素联系的示意图 |
| 4 | Demand 需求 | Plot a demand curve using given data 用给定数据画一条需求曲线 |
| 5 | Supply 供给 | Explain why a baker supplies more cakes when price rises 解释为何面包师在价格上涨时供应更多蛋糕 |
| 6 | Market equilibrium 市场均衡 | Find equilibrium price from a table, explain surplus/shortage 从表格中找出均衡价格，解释过剩与短缺 |
| 7 | Money and its functions 货币及其职能 | Compare barter and money with a real‑life example 用现实案例对比物物交换与货币 |
| 8 | Budgeting and saving 预算与储蓄 | Create a weekly budget for a fictional allowance of £15 为虚拟的15英镑零用钱编制周预算 |
| 9 | Economic systems 经济系统 | Match a description to market/command/mixed 将描述与市场/计划/混合经济匹配 |
| 10 | Full revision quiz 全范围复习小测 | Complete 15 multiple‑choice questions and self‑mark 完成15道选择题并自评 |
On each study day, start by reviewing the English and Chinese key terms for the topic, then complete the task and finally explain what you have learned to a family member. This bilingual approach strengthens your command of both languages and deepens your understanding. Remember, consistency matters more than long hours – short, focused sessions are the secret to effective revision.
在每个学习日，先复习该主题的中英文关键术语，然后完成任务，最后向一位家人解释你所学到的内容。这种双语方法能增强你对两种语言的掌握并加深理解。记住，持之以恒比长时间学习更重要——短时、专注的复习是高效学习的秘诀。
