📚 Year 7 Edexcel Economics Vocabulary Quick Study Guide | Edexcel 七年级经济学词汇术语速记指南
Starting economics in Year 7 is much easier when you can quickly recall the core vocabulary. This guide transforms tricky terms like scarcity, opportunity cost and factors of production into simple memory hooks — including stories, acronyms and sound‑alike tricks — built for Edexcel learners. Each section pairs an English explanation with a Chinese translation, so you can anchor the meaning in two languages.
七年级刚开始接触经济学时，如果能快速回忆起核心词汇，学习就会轻松很多。本指南将稀缺性、机会成本、生产要素等棘手术语转化为简单的记忆挂钩，包括小故事、首字母缩略词和谐音技巧，专为 Edexcel 学生打造。每个部分都用英文解释搭配中文翻译，让你用两种语言牢牢锁定词义。
1. Needs and Wants | 需要与欲望
Needs are the bare essentials human beings cannot survive without: water, food, shelter, clothing and warmth. A simple memory acronym is NEWS — Nutrition, Water, Energy‑shelter, Safety. This reminds you that needs are about survival, not luxury.
需要是人类生存不可或缺的基本要素：水、食物、住所、衣物和温暖。一个简单的记忆缩写是 NEWS——营养、水、能源‑住所、安全。这提醒你，需要关乎生存，而非奢侈享受。
Wants are everything else you desire but can live without — from video games to designer trainers. Link the letter ‘W‘ with ‘wish’. If you only wish for something and would be fine without it, it is a want.
欲望是你渴望拥有但并非生存所必需的一切东西，从电子游戏到名牌运动鞋。把字母 ‘W‘ 跟 ‘wish‘（愿望）联系起来。如果你只是希望拥有某样东西而没有它也能正常生活，那就是欲望。
A classic classroom test: if you had to flee your home, you would grab water and a blanket (needs), not a games console (want). Picture a backpack labelled ‘NEWS’ to lock in the difference.
课堂上有一个经典测试：如果你不得不逃离住所，你会抓起水和毯子（需要），而不是游戏机（欲望）。想象一个贴着 ‘NEWS’ 标签的背包，就能牢牢记住二者区别。
2. Scarcity: The Basic Economic Problem | 稀缺性：基本经济问题
Scarcity means there are not enough resources to satisfy all human wants. Think of it as ‘scar city’ — a place where everything leaves a scar because there is never enough. The word itself contains ‘scar‘, which hints at the damage unlimited wants cause when resources are limited.
稀缺性是指没有足够的资源来满足人类所有的欲望。可以把它想象成 ‘疤痕之城’ ——在那里，一切都会留下疤痕，因为永远都不够用。这个词本身就包含了 ‘scar‘（疤痕），暗示当资源有限时，无限的欲望会造成伤害。
Because of scarcity, every society must answer three big questions: What to produce? How to produce? For whom to produce? Remember the three WH‑words: What, How, Whom. Repeat ‘What, How, Whom’ like a chant.
由于稀缺性的存在，每个社会都必须回答三个重大问题：生产什么？如何生产？为谁生产？记住这三个 WH 疑问词：What, How, Whom。像念咒一样重复 ‘What, How, Whom’。
Scarcity is not the same as a shortage. A shortage is temporary; scarcity is permanent because our wants are endless. The ‘scar’ is forever — no bandage can cover it up. This idea is the very reason we study economics.
稀缺性并不等同于短缺。短缺是暂时的；稀缺性是永久的，因为我们的欲望无穷无尽。这道 ‘疤痕’ 是永恒的 —— 它没有创可贴能遮掩。这个理念正是我们学习经济学的根本原因。
3. Opportunity Cost and Trade‑offs | 机会成本与权衡取舍
Opportunity cost is the value of the next best alternative you give up when making a choice. It is not all the options you forgo, just the single best one. Memorise it as ‘the cost of the road not taken’. Every time you choose to revise economics instead of playing football, the fun of football is your opportunity cost.
机会成本是你做出选择时所放弃的次优替代选项的价值。它不是所有放弃的选项，而是唯一最好的那一个。把它记成 ‘那条未走之路的成本’。每当你选择复习经济学而不是踢足球时，足球的乐趣就是你的机会成本。
Use the formula OC = benefit of best forgone option − benefit of chosen option only if you need to calculate, but for Year 7 just imagine a scale: you weigh one activity against the next best one. The heavier side wins, but the lighter side is your opportunity cost.
如果需要计算，可以使用公式 OC = 放弃的最佳选项的收益 − 所选选项的收益，但对于七年级来说，只需想象一架天平：你把一项活动与次优活动放在两端。较重的一端胜出，而较轻的一端就是你的机会成本。
A trade‑off is a situation where you have to give up one thing to get more of another. Think ‘trade’ = you swap one goal for another. Scarcity forces us into trade‑offs every day. If you save more pocket money, you sacrifice spending now — that is a trade‑off.
权衡取舍是一种你必须放弃一样东西以获取更多另一样东西的情形。想一下 ‘trade’（交易）—— 你用一个目标交换另一个目标。稀缺性每天都在迫使我们做出权衡取舍。如果你把更多的零花钱存起来，就牺牲了当前的消费，这就是一种权衡取舍。
4. Goods and Services | 商品与服务
Goods are physical items you can touch, like a book, a sandwich or a smartphone. Services are actions done for you, such as a haircut, a bus ride or a maths lesson. Try the handshake rule: if you can shake hands with the provider after the purchase, it is a service; if you walk away holding something, it is a good.
商品是你可以触摸到的有形物品，比如一本书、三明治或智能手机。服务是为你执行的行为，如理发、公交车行程或数学课。试试握手规则：如果你购买后能和提供服务的人握手，那就是服务；如果你手里拿着东西离开，那就是商品。
To remember the spelling, link goods with ‘good stuff you can hold’ — both start with ‘goo‑’. And services contains ‘serve’, hinting that someone serves you. Many things we buy combine a good and a service, like a restaurant meal: the food is a good, the waiter’s help is a service.
要记住拼写，把 goods 与 ‘good stuff you can hold’（你可以拿在手里的好东西）联系起来——它们都以 ‘goo‑’ 开头。而 services 包含 ‘serve’，暗示有人为你服务。我们购买的许多东西都结合了商品和服务，例如餐馆用餐：食物是商品，服务员的服务则是服务。
5. Producers and Consumers | 生产者与消费者
Producers make or supply goods and services. Consumers use them. The two groups are linked by the circular flow of the economy. Picture a seesaw: the producer pushes goods onto one end, and the consumer’s payment pushes back from the other end.
生产者制造或提供商品和服务。消费者使用它们。这两大群体通过经济的循环流动联系在一起。想象一个跷跷板：生产者把商品推向一端，消费者的付款从另一端推回来。
The word ‘producer‘ hides ‘produce’ — someone who brings something new into existence. ‘Consumer‘ contains ‘consume’, meaning to use up. If you eat an apple, you consume it. The farmer who grew it is the producer. Remember: the farmer is the pro who duces the apple.
单词 ‘producer‘ 里面藏着 ‘produce’（生产），即创造出新东西的人。’Consumer‘ 包含了 ‘consume’，意思是消耗、用光。如果你吃掉一个苹果，你就是消费者。种植苹果的农民就是生产者。记住：农民是生产出苹果的专业人士。
6. Supply and Demand | 供给与需求
Demand is the quantity of a good or service that consumers are willing and able to buy at different prices. Supply is the quantity producers are willing and able to sell. To separate them, imagine a shop: customers on one side demand, shelves on the other side supply.
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。要区分它们，想象一家商店：一侧的顾客代表需求，另一侧的货架代表供给。
Law of Demand: when price falls, quantity demanded rises — think ‘low price, high demand’. Law of Supply: when price rises, quantity supplied rises — ‘high price, high supply’. Draw a small cross with a downward slope for demand and an upward slope for supply. The slopes themselves tell the story: demand dives, supply soars.
需求定律：价格下跌，需求量上升——想成 ‘低价，高需求’。供给定律：价格上升，供给量上升——’高价，高供给’。画一个小十字，需求线向下倾斜，供给线向上倾斜。斜率本身就讲述了一个故事：需求跳水，供给攀升。
Where the two lines meet is the market equilibrium. Use the phrase ‘Equilibrium is where Everything Evens out’. No shortage, no surplus — just right.
两条线相交的地方就是市场均衡。用一句话记忆：’Equilibrium’ 就是一切 ‘even out’（扯平）的地方。既没有短缺，也没有过剩，正好合适。
7. Markets and Prices | 市场与价格
A market is anywhere buyers and sellers come together to exchange goods, services or money. It does not have to be a physical place — online shops are markets too. Think of it as a ‘meeting match’ where demand and supply shake hands.
市场是买卖双方聚集在一起交换商品、服务或金钱的场所。它不一定是实体的场所——网店也是市场。可以把它想象成一个 ‘配对见面会’，需求与供给在那里握手。
Price is the signal that coordinates decisions. If a toy becomes scarce, its price rises, telling producers to make more and consumers to buy less. Call it the ‘price flashlight‘ shining on what to produce. The word ‘price’ sounds like ‘prize’ — it is the prize that matches buyers with sellers.
价格是协调决策的信号。如果一个玩具变得稀缺，它的价格就会上升，这告诉生产者要多生产，消费者要少购买。称它为’价格手电筒‘，照亮了该生产什么的方向。’Price’ 听起来像 ‘prize’（奖品）——它是连接买方与卖方的奖品。
8. Money, Exchange and Value | 货币、交换与价值
Money is anything widely accepted as a medium of exchange, a unit of account and a store of value. Bartering means swapping one good for another without money. Barter requires a ‘double coincidence of wants’ — both people must want what the other offers, which is rare.
货币是任何被广泛接受作为交换媒介、计价单位和价值储藏的东西。物物交换意味着不用钱直接互换商品。物物交换需要 ‘需求的双重巧合’——双方都必须想要对方提供的东西，这种情况非常少见。
To recall the functions of money, use the acronym MUS: Medium of exchange, Unit of account, Store of value. Think of music — money makes the economy ‘sing’ by enabling these three roles.
要记住货币的功能，使用首字母缩略词 MUS：Medium of exchange（交换媒介）、Unit of account（计价单位）、Store of value（价值储藏）。想想音乐（music）——货币通过实现这三大功能，让经济随之 ‘歌唱’。
9. Budgets, Saving and Choice | 预算、储蓄与选择
A budget is a plan for spending and saving money over a set period. It balances income against expenses. The word ‘budget’ sounds like ‘bucket’ — picture your money sitting in a leaky bucket; budgeting patches the holes so you do not run dry.
预算是一段时期内收入和支出的计划。它让收入与支出保持平衡。’Budget’ 听起来像 ‘bucket’（水桶）——想象你的钱在一个漏水的水桶里；做预算就是补上漏洞，以免水漏光。
Saving means setting aside part of your income for future use instead of spending it all now. Link saving with a piggy bank: when you save, you feed the pig so it will support you later. Every saving decision involves a trade‑off because you give up current consumption to gain future security.
储蓄是把收入的一部分存起来以备将来使用，而不是现在全部花光。将 saving 与存钱罐联系起来：你存钱时，就是在喂养这头小猪，它日后会回报你。每一个储蓄决策都涉及权衡取舍，因为你放弃了当前消费以换取未来的保障。
10. Factors of Production | 生产要素
Economists group resources into four factors: land, labour, capital and enterprise. Use the word LEK‑E (or say ‘leaky’) to remember Land, Labour (L and L are in ‘LL’), Capital, Enterprise — but actually it is Land, Labour, Capital, Enterprise, so the mnemonic “Lucy Likes Chocolate Eggs” works perfectly.
经济学家将资源分为四类：土地、劳动、资本和企业家才能。用句子 ‘Lucy Likes Chocolate Eggs’ 来记忆：对应 Land, Labour, Capital, Enterprise —— 露西喜欢巧克力蛋。
Land covers all natural resources (forests, minerals, seas). Labour is human effort. Capital is man‑made tools and machinery, not money. Enterprise is the risk‑taking ability that brings the other three together. Think of an entrepreneur as a chef mixing L‑L‑C into a recipe.
土地包括所有自然资源（森林、矿产、海洋）。劳动是人类的努力。资本是人造的工具和机器，而不是金钱。企业家才能是把另外三者组织起来并承担风险的能力。可以把企业家想象成一位厨师，正在把 L‑L‑C 混合成一道菜谱。
11. Specialisation and Division of Labour | 专业化与劳动分工
Specialisation occurs when a person, firm or country focuses on producing a narrow range of goods or services. Division of labour is breaking a production process into small tasks, each done by a different worker. Both raise productivity — output per unit of input.
专业化是指个人、企业或国家专注于生产少数几种商品或服务。劳动分工是把生产过程拆分成若干小任务，每个工人负责其中一项。两者都会提高生产率——即单位投入的产出。
Think of a sandwich shop: one person slices bread, another spreads butter, another adds filling. Each becomes faster at their tiny job. This is the division of labour. The shop specialises in sandwiches, not pizzas. The acronym D‑S reminds you: Divide the job, Specialise the skill.
想象一家三明治店：一个人切面包，另一个人涂黄油，还有人负责加馅料。每个人在他们细小的工序上越来越快。这就是劳动分工。这家店专门做三明治，而不做披萨。缩写 D‑S 提醒你：分解工作（Divide），专精技艺（Specialise）。
12. Making Sustainable Choices | 做可持续的选择
Sustainable choices meet our current needs without harming the ability of future generations to meet theirs. The word ‘sustain’ means to support for a long time. Economics teaches us that resources are scarce, so using them responsibly today keeps the ‘scar’ from growing for those who come after us.
可持续的选择是既能满足我们当代人的需要，又不损害后代人满足其需要的能力。’Sustain’ 的意思就是长期支撑。经济学告诉我们资源是稀缺的，因此今天负责任地使用资源可以防止那道 ‘疤痕’ 对后人越扩越大。
Whenever you recycle, turn off unused lights or choose a reusable bottle, you are making an economic decision with a long‑term view. The opportunity cost of waste today might be a missing resource tomorrow. Remember the two ‘R’s in ‘sustainable’: Respect and Renew.
每当你进行回收、关闭不用的灯或选择可重复使用的水瓶时，你都是在以长远眼光做经济决策。今天浪费的机会成本可能是明天某种资源的缺失。记住 ‘sustainable’ 中的两个 ‘R’：Respect（尊重）和 Renew（再生）。
