欢迎来到 Year 7 SQA 经济学术语速记指南。经济学研究的是人们在面对稀缺时如何做出选择。掌握词汇就像是打造一套理解世界运行方式的工具包。本指南提供了简单的定义、生活中的例子以及轻松的记忆诀窍，帮助你快速准确地记住每一个术语。通过将新词汇与你熟悉的画面和故事联系起来，你会发现即使复杂的概念也能变得得心应手。
1. Needs vs. Wants | 需要与欲望
Needs are the essential items required for human survival, such as food, clean water, shelter, clothing and warmth. Without them, life would be at serious risk. In economics, needs are considered basic requirements that everyone must have.
需要是人类生存所必需的物品，例如食物、清洁的饮水、住所、衣物和保暖。没有这些，生命会受到严重威胁。在经济学中，需要被看作每个人必须拥有的基本条件。
Wants, on the other hand, are things we would like to have but are not necessary for survival. Examples include a latest smartphone, a new video game, designer trainers or a holiday abroad. Wants are unlimited and can change with age, trends and income.
欲望则是我们希望拥有、但并非生存所必需的东西。例如最新款的智能手机、新的电子游戏、名牌运动鞋或海外度假。欲望是无限的，并且会随着年龄段、潮流和收入水平而变化。
A memory trick: the word 'Need' starts with 'N', just like 'Necessity'. 'Want' starts with 'W', like 'Wish'. Every time you see a label, ask yourself: is this necessary (N) or just a wish (W)?
记忆诀窍：单词 Need 以 N 开头，就像 Necessity（必要性）。Want 以 W 开头，就像 Wish（愿望）。每次看到商品标牌，可以问自己：这是必要的（N）还是只是个愿望（W）？
2. Scarcity and Choice | 稀缺与选择
Scarcity is the fundamental economic problem: unlimited wants but limited resources. There is never enough time, money or raw materials to satisfy everyone's desires. Even in rich countries, resources like fresh water or hospital beds can be scarce.
稀缺性是经济学的根本问题：无限的欲望面对有限的资源。永远不会有足够的时间、金钱或原料来满足所有人的欲望。即使在富裕的国家，像淡水或医院床位这样的资源也可能是稀缺的。
Because of scarcity, people, businesses and governments must make choices. Choosing means deciding between alternatives. For instance, a student with only one free hour must choose between studying and playing video games. Scarcity forces everyone to prioritise.
由于稀缺性，个人、企业和政府都必须做出选择。选择意味着在不同选项之间做出决定。例如，一个只有一小时空闲的学生必须在学习和打电子游戏之间选择。稀缺性迫使每个人设立优先次序。
To remember scarcity, picture a crowded city where everything is running out – a 'Scarce City'. The word 'scarce' is right there inside 'scarcity'. Choice can be recalled by the idea of 'picking one and letting go of another'.
要记住稀缺性，可以想象一个拥挤的城市，里面所有东西都快用光了——“稀缺之城”。单词 scarce 就藏在 scarcity 里面。选择可以这样记忆：拿起一个，放下另一个。
3. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative that you give up when a decision is made. It is not about all the options you could have chosen; it focuses on the single most valuable opportunity you lose. Every choice carries an opportunity cost.
机会成本是你做出决定时所放弃的次优选项的价值。它不是你本可以选择的全部选项，而是你失去的唯一最有价值的机会。每个选择都伴随着机会成本。
For example, imagine you receive £10 as a gift. You can either buy a cinema ticket or a new book. If you choose the cinema, the opportunity cost is the enjoyment and learning you would have gained from the book. This idea helps explain why smart decisions require weighing what is sacrificed.
例如，假设你收到10英镑作为礼物。你可以买一张电影票或一本新书。如果你选择了电影，机会成本就是你会从书中获得的乐趣和知识。这个概念解释了为什么明智的决定需要权衡所牺牲的东西。
Memory helper: think of 'opportunity cost' as the 'opportunity you lost'. In Chinese, the term "机会成本" directly translates as 'the cost of an opportunity missed', which is a perfect clue.
记忆助手：把 opportunity cost 想成 'the opportunity you lost'（你丢失的机会）。中文术语“机会成本”直接翻译过来就是“错失机会的代价”，这恰好是一条完美的线索。
4. Goods and Services | 商品与服务
Goods are physical, tangible items that can be seen and touched. Examples include apples, textbooks, bicycles and clothing. Economists often call them tangible goods because they have a material form. Goods can be stored and used later.
商品是指看得见、摸得着的实物物品。例如苹果、课本、自行车和衣物。经济学家常称它们为有形商品，因为它们具有物质形态。商品可以被储存起来以后使用。
Services are activities or benefits provided by one party to another. They are intangible – you cannot hold them in your hand. Haircuts, bus journeys, online tutoring and medical check-ups are all services. Services are consumed at the point where they are produced.
服务是一方向另一方提供的活动或利益。它们是无形的一你无法握在手中。理发、公交乘车、在线辅导和医疗检查都属于服务。服务在生产的同时被消费。
A quick recall method: if you can drop it on your foot, it is probably a Good. If someone has to do it for you, it is a Service. The Chinese "商品" (goods) contains "品" which suggests an object, and "服务" (service) implies serving.
快速记忆法：如果掉下来会砸到脚，那很可能是商品。如果必须有人为你做，那就是服务。中文里“商品”带有“品”（物品），“服务”则意味着为你做事。
5. Producers and Consumers | 生产者与消费者
Producers are the individuals, businesses or organisations that make goods or supply services. Farmers growing wheat, factories assembling laptops, and hospitals delivering healthcare are all producers. They combine resources such as labour, land and capital to create output.
生产者是制造商品或提供服务的个人、企业或组织。种小麦的农民、装配笔记本电脑的工厂、提供医疗服务的医院都是生产者。他们组合劳动力、土地和资本等资源来创造产出。
Consumers are the people who buy and use goods and services to satisfy their needs and wants. Every time you purchase a snack, take a bus ride or use electricity, you act as a consumer. The choices consumers make send signals to producers about what to supply.
消费者是购买和使用商品与服务以满足自身需要和欲望的人。每当你购买零食、乘坐公交车或使用电力时，你就在扮演消费者的角色。消费者做出的选择会向生产者传递该供应什么的信号。
Memorisation trick: 'Producer' contains 'produce' – they produce. 'Consumer' reminds us of 'consume' like eating a meal. In Chinese, "生产者" literally means the one who produces, and "消费者" means the one who consumes and spends.
记忆诀窍：Producer 里面有 produce——他们生产。Consumer 让人联想到 consume（消费），就像吃掉一餐饭。中文里“生产者”字面意思是创造产出的人，“消费者”则是消费花费的人。
6. Supply and Demand | 供给与需求
Demand refers to how much of a product consumers are willing and able to buy at different prices. Usually, when prices fall, people want to buy more; when prices rise, they buy less. This relationship is called the law of demand.
需求指的是在不同价格水平下消费者愿意且能够购买的商品数量。通常，当价格下降时，人们想买得更多；价格上升时，则买得更少。这种关系称为需求定律。
Supply is how much of a product producers are willing and able to offer for sale at different prices. Generally, a higher price encourages producers to supply more because they can earn more profit. This is known as the law of supply.
供给是指在不同价格水平下生产者愿意且能够出售的商品数量。一般来说，更高的价格会激励生产者提供更多，因为他们可以获得更多利润。这被称为供给定律。
A memory tip: think of 'Demand' from the buyer's side – both start with 'D' (Demand, Desiring buyers). 'Supply' is from the seller's side – both start with 'S' (Supply, Selling). In Chinese, "需求" (need + seek) and "供给" (provide + give) clearly show who does what.
记忆提示：从买方角度想 Demand——都以 D 开头（Demand, Desiring buyers）。Supply 从卖方角度——都以 S 开头（Supply, Selling）。中文里“需求”包含“求”（购买者求购），“供给”包含“供”（生产者提供）。
7. Market and Price | 市场与价格
A market is any arrangement that brings buyers and sellers together to exchange goods, services or resources. It does not have to be a physical place – online markets and phone-based trades also count. Markets help determine the price through the interaction of supply and demand.
市场是指任何将买方和卖方聚集在一起交换商品、服务或资源的安排。它不一定是一个实体场所——在线市场和电话交易也算。市场通过供给和需求的相互作用帮助确定价格。
Price is the amount of money that has to be paid to obtain a product or service. Prices act as signals that coordinate decisions. A high price tells producers to make more and tells consumers to use less; a low price does the opposite.
价格是为获得一件商品或服务而必须支付的货币数额。价格作为信号起到协调决策的作用。高价格告诉生产者多生产，告诉消费者少使用；低价格则相反。
Remember: a market is like a meeting point (imagine a town market square). Price is the 'tag' on the stall. In Chinese, "市场" (market) can be thought of as the 'city field' where trade happens, and "价格" (price) is about the 'value and standard' set.
记忆要点：市场就像一个会面点（想象城镇的集市广场）。价格是摊位上的“标签”。在中文里，“市场”可以看作交易发生的“市井之场”，“价格”则是关于设定的“价值与标码”。
8. Money and Barter | 货币与物物交换
Barter is the direct exchange of one good or service for another without using money. For example, a farmer giving wheat to a baker in return for bread is barter. Barter requires a double coincidence of wants – both parties must want what the other is offering at the same time.
物物交换是指不通过货币而直接以一种商品或服务交换另一种商品或服务。例如农民用小麦交换面包师的面包。物物交换要求“需求的双重巧合”——双方必须同时想要对方提供的东西。
Money is any item widely accepted as payment for goods, services and debts. Modern money serves three main functions: it is a medium of exchange, a store of value and a unit of account. Money removes the heavy inconvenience of barter.
货币是指任何被广泛接受作为商品、服务和债务支付手段的物品。现代货币有三大功能：交换媒介、价值储藏和计价单位。货币消除了物物交换的严重不便。
Memory aid: barter swaps 'goods for goods', while money makes trade 'flexible'. In Chinese, "物物交换" literally means 'object-to-object exchange', and "货币" (money) goes back to 'currency goods'. Think of money as a shortcut that everyone trusts.
记忆辅助：物物交换是“货物换货物”，货币则使交易“灵活”。中文里“物物交换”字面意思就是物体对物体的交换，“货币”可以追溯到“流通的货品”。把货币想象成每个人都信任的捷径。
9. Budgeting and Saving | 预算与储蓄
A budget is a plan that shows expected income and how it will be spent over a period of time. Individuals, households and governments all use budgets to make sure they do not run out of money. A budget typically includes categories such as food, rent, entertainment and savings.
预算是一份展示一段时期内的预期收入以及收入将如何支出的计划。个人、家庭和政府都使用预算来确保不会把钱花光。预算通常包括食品、住房、娱乐和储蓄等类别。
Saving is the portion of income that is not spent but set aside for future use. People save for emergencies, large purchases like a bicycle, or long-term goals such as university. Saving requires self-discipline and often involves putting money in a bank account.
储蓄是指收入中没有被花掉、而是留作将来使用的那部分。人们为紧急情况、购买像自行车这样的大件商品或上大学等长期目标而储蓄。储蓄需要自律，通常包括将钱存入银行账户。
To remember budget, imagine a boundary line for your coins – a 'budget edge'. The Chinese word "预算" (advance calculate) reminds you to calculate before spending. Saving can be pictured like a squirrel storing nuts for winter – "储蓄" means 'storing and accumulating'.
记忆预算：想象一条围绕你的硬币的边界线——预算边界。中文“预算”提示你在消费之前先计算。储蓄可以想象成松鼠为过冬储存坚果——“储蓄”的意思是“储存和积蓄”。
10. Interest and Banks | 利息与银行
Interest is the fee paid to borrow money, or the reward received for saving. If you deposit £100 in a bank account with 3% annual interest, you earn £3 at the end of the year. If you borrow £100 from a bank, you must repay the £100 plus interest as the cost of borrowing.
利息是借款时支付的费用，或是存款时获得的回报。如果你将100英镑存入年利率3%的银行账户，年底你会得到3英镑利息。如果你从银行借100英镑，你必须偿还100英镑加上利息作为借款成本。
Banks are financial institutions that accept deposits, offer loans and provide payment services. They act as intermediaries between savers who want to earn interest and borrowers who are willing to pay interest. Banks also help money circulate safely in the economy.
银行是接收存款、提供贷款以及提供支付服务的金融机构。它们在希望赚取利息的储蓄者和愿意支付利息的借款人之间充当中介。银行还帮助货币在经济中安全地流通。
Remember: interest is the 'price of money'. The word 'interest' can be linked to 'extra' – you get extra on savings and pay extra on loans. In Chinese, "利息" (profit interest) combines 'profit' and 'interest', which makes sense as a small gain. Banks are the 'money warehouses'.
记忆要点：利息就是“货币的价格”。interest 这个词可以和“extra”（额外的）联系起来——存款多得，借款多付。中文里“利息”结合了“利”（利润）和“息”（子息），看作一种小收益很合理。银行则是“金钱仓库”。
11. Imports and Exports | 进口与出口
Imports are goods and services bought from another country and brought into the home country. For example, a UK supermarket selling bananas from Costa Rica is dealing with imports. A country imports when domestic production cannot meet demand or when foreign products are cheaper or of better quality.
进口是指从另一个国家购买并输入本国的商品和服务。例如，英国超市出售来自哥斯达黎加的香蕉就涉及进口。当国内生产无法满足需求，或者外国产品更便宜、质量更好时，一个国家就会进口。
Exports are goods and services sold to another country and sent overseas. When a Scottish whisky company sells bottles to Japan, it is exporting. Exports bring money into the country and create jobs. The balance between imports and exports affects a nation's economy.
出口是指出售到另一个国家并运往海外的商品和服务。当苏格兰威士忌公司将酒瓶销往日本时，就是在出口。出口为国家带来收入并创造就业。进口与出口之间的平衡会影响一国经济。
Memory magic: 'Im' equals 'in' and 'Ex' equals 'exit'. Imagine imports coming into your house through the front door, and exports going out. In Chinese, "进口" literally means 'enter port', and "出口" means 'exit port', which perfectly captures the direction.
记忆魔法：Im 等于 in（进入），Ex 等于 exit（出去）。想象进口从大门进入你的房子，出口则走出去。中文里“进口”字面意思是“进入口岸”，“出口”是“走出口岸”，完美体现了方向。
12. Taxes and Government Spending | 税收与政府支出
Taxes are compulsory payments made by individuals and businesses to the government. They are not voluntary purchases but legal obligations. Common types include income tax taken directly from wages, and VAT (Value Added Tax) added to many goods and services at the point of sale.
税收是个人和企业强制向政府缴纳的款项。它们不是自愿购买，而是法定义务。常见的类型包括直接从工资中扣除的所得税，以及在销售时加在许多商品和服务上的增值税。
Government spending uses tax revenue to provide public goods and services that benefit everyone – such as state schools, the NHS in Scotland, roads, street lighting and defence. Because these services are shared by all, they are often called public services.
政府支出使用税收收入来提供使所有人受益的公共商品和服务——比如公立学校、苏格兰的国民医疗服务体系、公路、路灯和国防。由于这些服务由所有人共享，所以常被称为公共服务。
To fix them in your mind, think of taxes as 'the price of a civilised society'. The word 'tax' can be tied to 'taking a share'. In Chinese, "税收" implies 'tax collection and receiving'. And government spending – "政府支出" – literally means 'the government pays out' for the public good.
