经济学有时感觉像在学一门新语言。这份速记指南用简单的定义和巧妙的记忆技巧，拆解 Year 8 WJEC 必备术语，让你能流利地说“经济语”，在评估中表现出色。
1. The Basic Economic Problem | 基本经济问题
We have unlimited wants but only limited resources. This is the fundamental reason we study economics – to understand how people make choices under scarcity.
我们有无限的欲望，但资源有限。这就是我们学习经济学的根本原因——理解人们如何在稀缺条件下做出选择。
Memory trick: Think of a child in a sweet shop with only £1. They want everything (unlimited wants) but can only pick a few sweets (limited resources). This tension is the basic economic problem.
记忆技巧：想象一个小孩在糖果店里只有1英镑。他们什么都想要（无限欲望），但只能选几颗糖（有限资源）。这种矛盾就是基本经济问题。
2. Needs and Wants | 必需品与欲望
Needs are things we must have to survive, like water, food, shelter, and clothing. Wants are everything else we desire but could live without, such as video games, holidays, or designer trainers.
必需品是我们生存所必须拥有的东西，如水、食物、住所和衣服。欲望则是我们想要但并非生活必需的其他一切，比如电子游戏、假期或名牌运动鞋。
Memory trick: "Need NOW, Want WOW." Needs are for now survival; wants give us wow moments.
记忆技巧：“必需品是立即需要（NOW），欲望是让人惊喜（WOW）。”必需品关乎当下生存；欲望带来惊喜时刻。
3. Scarcity | 稀缺性
Scarcity means there are not enough resources to satisfy all our wants. It forces us to make decisions about what to produce, how to produce, and for whom to produce.
稀缺性指没有足够的资源来满足我们所有的欲望。它迫使我们要决定生产什么、如何生产以及为谁生产。
Memory trick: Picture a city with a scar (SCAR-city) – the scar represents that something is always in short supply. Scarcity is the scar that never fully heals in any economy.
记忆技巧：想象一座有伤疤的城市（SCAR-city）——伤疤代表总有什么东西供应不足。稀缺性就是任何经济体中永远不会完全愈合的伤痕。
4. Opportunity Cost | 机会成本
Opportunity cost is the next best alternative you give up when making a choice. It is not all the alternatives, only the most valued one you sacrificed.
机会成本是你做选择时放弃的下一个最佳替代品。它不是所有替代品，只是你牺牲掉的最有价值的那一个。
Memory trick: "Opportunity knocks, but cost blocks." When you choose one door (opportunity), the cost is the door you leave closed. Always ask: "What is the one thing I am missing out on?"
记忆技巧：“机会来敲门，成本关上门。”当你选择一扇门（机会）时，成本就是你关上的那扇门。总问问自己：“我错过的唯一一件事是什么？”
5. Factors of Production | 生产要素
The four factors of production are land, labour, capital, and enterprise. Land includes all natural resources; labour is the human effort; capital is man-made tools and machinery; enterprise is the risk-taking ability to bring the other factors together.
四种生产要素是土地、劳动力、资本和企业家才能。土地包括所有自然资源；劳动力是人类的努力；资本是人造的工具和机器；企业家才能是将其他要素组合起来的风险承担能力。
| Factor | English example | 中文示例 |
| Land | Oil, forests, water | 石油、森林、水 |
| Labour | Teacher, builder | 教师、建筑工人 |
| Capital | Hammer, factory | 锤子、工厂 |
| Enterprise | Entrepreneur starting a business | 创业的企业家 |
Memory trick: Remember the word "LACE" – Land, lAbour, Capital, Enterprise. A lace ties all factors together.
记忆技巧：记住单词“LACE”——土地(Land)、劳动力(lAbour)、资本(Capital)、企业家才能(Enterprise)。一根花边（lace）把所有要素系在一起。
6. Goods and Services | 商品与服务
Goods are tangible items you can touch, like a book or a bicycle. Services are intangible actions done for you, such as a haircut, a bus ride, or streaming a film.
商品是可以触摸的有形物品，比如一本书或一辆自行车。服务是为你完成的无形行为，比如理发、乘坐公交车或在线观看电影。
Memory trick: "Goods are good in your hands; services stay in the air." If you can hold it, it's a good; if it happens for you, it's a service.
记忆技巧：“商品握在手中，服务留在空气里。”你能拿住它，就是商品；为你发生的事，就是服务。
7. Supply and Demand | 供给与需求
Demand is how much of a product consumers are willing and able to buy at different prices. Supply is how much producers are willing and able to offer for sale. Price is determined where supply equals demand – the equilibrium.
需求是指在不同价格下消费者愿意且能够购买的产品数量。供给是生产者愿意且能够提供的销售数量。价格由供给等于需求时的均衡点决定。
Memory trick: "Supply goes up, demand comes down, price goes round and round." Sing it like a nursery rhyme. When supply rises, price falls; when demand rises, price rises.
记忆技巧：“供给往上涨，需求往下降，价格转圈圈。”像童谣一样唱出来。供给增加，价格下跌；需求增加，价格上涨。
Equilibrium price: Qd = Qs
均衡价格：需求量 = 供给量
8. Market and Price Mechanism | 市场与价格机制
A market is any place or system where buyers and sellers exchange goods or services. The price mechanism describes how prices act as signals to allocate scarce resources; rising prices encourage more production, falling prices discourage it.
市场是买方和卖方交换商品或服务的任何场所或体系。价格机制描述价格如何充当信号来分配稀缺资源；价格上涨鼓励更多生产，价格下跌则抑制生产。
Memory trick: Think of prices as traffic lights: green (high price) says "go, produce more"; red (low price) says "stop, produce less".
记忆技巧：把价格想象成交通信号灯：绿灯（高价）说“走，多生产”；红灯（低价）说“停，少生产”。
9. Inflation | 通货膨胀
Inflation is a sustained rise in the general level of prices for goods and services over time. As inflation rises, each pound buys fewer items.
通货膨胀是指一段时间内商品和服务总体价格水平的持续上涨。通胀上升时，每英镑能买到的东西变少。
Memory trick: "Inflate a balloon – prices blow up." Imagine your money shrinking while the economy balloon expands.
记忆技巧：“给气球充气——价格膨胀。”想象你的钱在缩水，而经济气球在膨胀。
10. Economic Growth | 经济增长
Economic growth measures an increase in the output of goods and services in a country over a period. It is often shown by a rise in Gross Domestic Product (GDP). Growth means more jobs and higher living standards typically.
经济增长衡量一个国家在一段时间内商品和服务产出的增加。通常以国内生产总值（GDP）的增长来显示。增长通常意味着更多就业和更高生活水平。
Memory trick: "Growth grows the pie." The economy's pie gets bigger, so everyone can have a slightly larger slice.
记忆技巧：“增长把饼做大。”经济的派变大了，每个人都能分到稍大的一片。
11. Specialisation and Trade | 专业化与贸易
Specialisation occurs when individuals, firms, or countries concentrate on producing a narrow range of goods or services where they have an advantage. Trade allows them to exchange surplus output for other goods they need.
专业化发生在个人、企业或国家集中生产自己有优势的少数商品或服务时。贸易使他们能用剩余产出交换自己需要的其他商品。
Memory trick: Like a school group project – one person does the research, another designs the poster. Everyone specialises, then trades their part to finish the project.
记忆技巧：就像学校小组项目——一人做研究，另一人设计海报。每个人专业化，然后交换自己的工作部分来完成项目。
12. Budget and Saving | 预算与储蓄
A budget is a plan for future income and spending. Saving is the part of income not spent on consumption. Understanding budgeting helps individuals and governments avoid debt and plan for the future.
预算是未来收入和支出的计划。储蓄是收入中没有用于消费的部分。理解预算有助于个人和政府避免债务、规划未来。
Memory trick: "Budget = money map." Just as a map guides a journey, a budget guides your money through the month.
记忆技巧：“预算 = 资金地图。”就像地图指引旅程，预算指引你的钱度过一个月。
