欢迎来到 Year 9 CCEA 经济学词汇速记指南。掌握关键术语是理解经济运行方式的第一步。本文将拆解你需要了解的基本术语，并提供记忆技巧和实例。让我们开始吧！
1. Scarcity and the Basic Economic Problem | 稀缺性与基本经济问题
Scarcity means that resources are limited, while human wants are unlimited. This mismatch creates the basic economic problem: what to produce, how to produce, and for whom to produce.
稀缺性意味着资源有限而人类的欲望无限。这种不匹配产生了基本的经济问题：生产什么、如何生产以及为谁生产。
Because of scarcity, individuals, businesses and governments must make choices. Every choice involves a trade-off – giving up something to get something else.
由于稀缺性的存在，个人、企业和政府都必须做出选择。每一个选择都涉及权衡取舍——放弃某物以获得另一物。
Memory Tip: Remember the word 'scarce' in scarcity – resources are scarce like a single pizza for a large party. The party must decide who gets what slice.
记忆技巧：记住 scarcity 中的 'scarce'——资源就像为一大群人准备的一张比萨一样稀少。聚会必须决定谁得到哪一片。
2. Needs and Wants | 需要与想要
Needs are things we must have to survive, such as food, water, shelter and clothing. Wants are things we desire but can live without, like video games, designer clothes or holidays.
需要是我们生存所必需的事物，比如食物、水、住所和衣物。想要是我们渴望但可以没有的事物，比如电子游戏、名牌服装或度假。
Economics studies how society uses scarce resources to satisfy both needs and wants. Since wants are unlimited, scarcity forces us to satisfy our needs first in most cases.
经济学研究社会如何使用稀缺资源来满足需要和想要。由于想要是无限的，稀缺性迫使我们在大多数情况下首先满足需要。
Memory Tip: Link 'N' for needs with 'Necessities' and 'W' for wants with 'Wishes'. Necessities are non‑negotiable; wishes can wait.
记忆技巧：将 'N' 代表的需要与 'Necessities'（必需品）联系起来，将 'W' 代表的想要与 'Wishes'（愿望）联系起来。必需品不可妥协；愿望可以等待。
3. Goods and Services | 商品与服务
Goods are physical, tangible items that you can see and touch, such as a smartphone, a sandwich or a textbook. Services are intangible actions provided by people, like a haircut, a bus journey or a music lesson.
商品是看得见摸得着的实物，比如智能手机、三明治或教科书。服务是人们提供的无形行为，比如理发、乘坐公交车或上音乐课。
Both goods and services are produced to satisfy human wants and needs. In a modern economy, services often account for a large share of total output.
商品和服务都是为了满足人类的想要和需要而生产的。在现代经济中，服务通常占总产出的很大一部分。
Memory Tip: Goods you can drop on your foot; services you cannot. Think of a 'good' as a 'thing you can hold'.
记忆技巧：商品你可以砸到脚上；服务则不能。想象 'good'（商品）是 '可以握住的东西'。
4. Factors of Production | 生产要素
The factors of production are the resources used to create goods and services. They are traditionally grouped into four categories: land, labour, capital and enterprise.
生产要素是用于创造商品和服务的资源，传统上分为四类：土地、劳动力、资本和企业家才能。
Land includes all natural resources such as forests, minerals, water and the soil itself. Labour refers to human physical and mental effort. Capital means man‑made goods used for further production, like machinery and factories. Enterprise is the ability to organise the other three factors and bear the risks of business.
土地包括所有自然资源，如森林、矿产、水和土壤本身。劳动力指人类的体力和脑力付出。资本指用于进一步生产的人造品，如机器和工厂。企业家才能是组织其他三种要素并承担商业风险的能力。
Memory Tip: Use the acronym 'L-L-C-E' (Land, Labour, Capital, Enterprise) or visualise a bakery: Land provides wheat, Labour is the baker, Capital is the oven, and Enterprise is the baker's risk‑taking idea.
记忆技巧：使用首字母缩略词 'L-L-C-E'（土地、劳动力、资本、企业家才能），或者想象一家面包店：土地提供小麦，劳动力是面包师，资本是烤炉，企业家才能是面包师的冒险创意。
5. Opportunity Cost | 机会成本
Opportunity cost is the value of the next best alternative that you give up when making a choice. It represents the true cost of any decision, beyond money alone.
机会成本是你做出选择时所放弃的次优选项的价值。它代表了任何决定的真实成本，而不仅仅是金钱。
For example, if you choose to spend an hour revising economics instead of playing football, the opportunity cost is the enjoyment and fitness you lose from missing the game.
例如，如果你选择花一小时复习经济学而不是踢足球，机会成本就是你因错过比赛而失去的乐趣和锻炼。
Memory Tip: Think of 'OC' as 'Opportunity Cut' – every choice cuts off the next best possibility. Ask yourself: 'What am I giving up?'
记忆技巧：将 'OC' 想成 'Opportunity Cut'（机会切除）——每个选择都切除了次优可能性。问自己：“我放弃了什么？”
6. Supply and Demand | 供给与需求
Demand is the willingness and ability of consumers to buy a good or service at various prices. Supply is the willingness and ability of producers to sell a good or service at various prices.
需求是消费者在不同价格下愿意并且能够购买商品或服务的程度。供给是生产者愿意并且能够在不同价格下出售商品或服务的程度。
The law of demand states that, all else being equal, as the price rises, quantity demanded falls. The law of supply states that as the price rises, quantity supplied rises, because higher prices encourage producers to supply more.
需求定律指出，在其他条件不变的情况下，价格上升，需求量下降。供给定律指出，价格上升，供给量上升，因为更高的价格会激励生产者提供更多。
Memory Tip: Demand slopes 'Down', like a slide. Supply slopes 'Up', like a rocket. Remember 'D for Down, S for Sky'.
记忆技巧：需求曲线向下倾斜，像滑梯，供给曲线向上倾斜，像火箭。记住 'D for Down, S for Sky'（D 向下，S 天空向上）。
7. Market and Price | 市场与价格
A market is any arrangement where buyers and sellers meet to exchange goods, services or resources. Markets can be physical, like a local stall, or virtual, like an online shop.
市场是买卖双方聚集在一起交换商品、服务或资源的任何安排。市场可以是有形的，如本地摊位，也可以是虚拟的，如网上商店。
The equilibrium price – or market price – is set where the quantity demanded equals the quantity supplied. This price clears the market, meaning no surplus or shortage exists.
均衡价格——即市场价格——在需求量等于供给量之处确定。这一价格出清市场，意味着不存在过剩或短缺。
Memory Tip: Imagine a market as a 'matchmaker' between buyers and sellers. The equilibrium is the 'handshake' where both sides agree on quantity and price.
记忆技巧：将市场想象成买卖双方的“媒人”。均衡就是双方在数量和价格上达成一致的“握手”。
8. Specialisation and Division of Labour | 专业化与分工
Specialisation occurs when individuals, firms or countries focus on producing a narrow range of goods or services in which they are relatively efficient. Division of labour is when the production process is broken into separate tasks, with each worker focusing on one step.
专业化是指个人、企业或国家专注于生产自己相对高效的一小部分商品或服务。分工是指将生产过程拆分为不同的工序，每个工人专注于其中一步。
Both concepts raise productivity because workers become quicker and more skilled at their specific tasks. They also save time by not switching between different jobs.
这两个概念都能提高生产率，因为工人在特定任务上变得更熟练、更快速。他们还因为无需在不同工作间切换而节省时间。
Memory Tip: Picture a sandwich assembly line: one person slices bread, another adds butter, the next adds filling. Each specialises, and the whole process speeds up.
记忆技巧：想象一条三明治装配线：一人切面包，另一人涂黄油，下一人加馅料。每个人都专业化，整个流程就加快了。
9. Entrepreneurs and Profit | 企业家与利润
An entrepreneur is someone who takes the risk of bringing together the other factors of production to start a business. They innovate, organise and make decisions.
企业家是承担风险、联合其他生产要素来创办企业的人。他们创新、组织并做出决策。
Profit is the financial reward entrepreneurs receive for their risk‑taking and effort. It is the surplus left after all costs have been paid. Without the prospect of profit, entrepreneurs would have little incentive to invest and create jobs.
利润是企业家因承担风险和付出努力而获得的经济回报。它是支付所有成本后剩下的盈余。如果没有利润前景，企业家就缺乏动力去投资和创造就业。
Memory Tip: Entrepreneur sounds like 'enterprise person'. Profit is their 'prize' for successfully combining land, labour and capital.
记忆技巧：Entrepreneur 听起来像 'enterprise person'（创业人）。利润是他们成功将土地、劳动力和资本结合后获得的“奖品”。
10. Money and Barter | 货币与以物易物
Before money existed, people used barter – the direct exchange of one good or service for another. Barter requires a double coincidence of wants: each trader must have what the other wants at the same time.
在货币出现之前，人们使用以物易物——直接用一种商品或服务交换另一种。以物易物需要需求双重巧合：每个交易者必须同时拥有对方想要的物品。
Money solves this problem by acting as a medium of exchange, a store of value and a unit of account. It makes trade much easier and more efficient.
货币通过充当交换媒介、价值储藏手段和计价单位来解决这个问题。它使贸易变得更容易、更高效。
Memory Tip: Think of barter as 'swap struggles', while money is a 'magic token' accepted by everyone. Double coincidence of wants is like needing to find a twin who wants exactly what you have and has exactly what you want.
记忆技巧：将以物易物想成“交换的挣扎”，而货币是人人接受的“魔法代币”。需求双重巧合就像是需要找到一个双胞胎：正好想要你有的东西，并正好拥有你想要的东西。
11. Economic Sectors | 经济部门
The economy is often divided into three main sectors: primary, secondary and tertiary. The primary sector involves extracting raw materials from nature, such as farming, fishing and mining.
经济通常分为三个主要部门：第一产业、第二产业和第三产业。第一产业涉及从自然界获取原材料，例如农业、渔业和采矿业。
The secondary sector manufactures goods by transforming raw materials into finished products, like turning wood into furniture or steel into cars. The tertiary sector provides services – from retail and teaching to finance and transport.
第二产业通过将原材料转化为成品来制造商品，例如将木材制成家具或将钢材制成汽车。第三产业提供服务——从零售、教育到金融和运输。
Memory Tip: Use 'PST' (Primary, Secondary, Tertiary). Primary 'Picks' from nature, Secondary 'Shapes' materials, and Tertiary 'Trades' or 'Treats' customers. You can also remember the sequence as you move from earth, to factory, to shop.
记忆技巧：使用 'PST'（第一、第二、第三产业）。Primary 从自然界“采摘”，Secondary 对材料进行“塑形”，Tertiary 对顾客进行“交易”或“服务”。你也可以记住这一顺序：从大地到工厂，再到商店。
