欢迎使用 Year 8 Cambridge 经济学的核心词汇指南。掌握关键术语是理解个人、企业和政府如何就资源做出选择的第一步。本指南采用简单的类比、记忆窍门和清晰的定义，帮助你快速记住每个概念。让我们把难懂的词语变成考试和日常生活中可用的工具。
1. Scarcity and Choice | 稀缺与选择
Scarcity means that there are not enough resources to satisfy all human wants. Because resources like time, money, and raw materials are limited, people must make choices. Every choice involves giving up something else. Think of scarcity as the reason you cannot have everything on your birthday list — you must pick what you value most.
稀缺是指没有足够的资源来满足人类所有的欲望。由于时间、金钱和原材料等资源是有限的，人们必须做出选择。每一个选择都涉及放弃其他东西。可以把稀缺当作你不能得到生日愿望清单上所有东西的原因——你必须挑选你最为珍视的。
Memory tip: 'Scarce' sounds like 'scare' — limited resources can be scary, reminding you to choose carefully.
记忆技巧：“Scarce（稀缺）”听起来像“scare（害怕）”——有限的资源可能让人害怕，提醒你谨慎选择。
2. Needs and Wants | 需要与欲望
Needs are things essential for survival, such as food, water, shelter, and clothing. Wants are desires for goods or services that are not necessary for survival, like video games, holidays, or designer clothes. Distinguishing between the two helps economists understand consumer behaviour.
需要是生存所必需的东西，比如食物、水、住所和衣服。欲望是对并非生存必需的商品或服务的渴望，比如电子游戏、度假或名牌服装。区分这两者有助于经济学家理解消费者行为。
Memory tip: Use 'N' for 'Necessary' (Needs) and 'W' for 'Wish' (Wants).
记忆技巧：用“N”对应“Necessary（必需的）”表示需要，用“W”对应“Wish（愿望）”表示欲望。
3. Goods and Services | 商品与服务
Goods are physical items you can touch, like apples, cars, or books. Services are actions performed for someone else, like teaching, haircuts, or transportation. Production in an economy includes both. Think of goods as 'things' and services as 'tasks'.
商品是你可以触摸到的有形物品，如苹果、汽车或书籍。服务是为他人执行的行为，如教学、理发或交通。一个经济体中的生产包括这两者。可以将商品视作“物品”，服务视作“任务”。
Memory tip: If you can drop it on your foot, it's a good; if not, it's a service.
记忆技巧：如果可以砸到你的脚，那就是商品；否则是服务。
4. Factors of Production | 生产要素
Factors of production are the resources used to make goods and services. They are often grouped as land, labour, capital, and enterprise. Land includes natural resources; labour is human effort; capital is man-made tools and machinery; enterprise is the skill of combining the other factors to create a business.
生产要素是用于生产商品和服务的资源，通常分为土地、劳动力、资本和企业家才能。土地指自然资源；劳动力是人的努力；资本是人造的工具和机器；企业家才能是组合其他要素来创立企业的技能。
Memory tip: Remember the acronym 'CELL' — Capital, Enterprise, Land, Labour. (Imagine them as the cell of production.)
记忆技巧：记住缩略词“CELL”——资本、企业家才能、土地、劳动力。（可想象它们是生产细胞。）
5. Opportunity Cost | 机会成本
Opportunity cost is the next best alternative you give up when you make a choice. It is not all the alternatives, only the one you value most after your choice. For example, if you spend £10 on a cinema ticket instead of a new book, the opportunity cost is the enjoyment you would have had from the book.
机会成本是你做出选择时放弃的次优替代品。它不是所有的替代选项，而只是你选择之后最看重的那个。例如，如果你花10英镑买电影票而不是一本新书，机会成本就是你从书中本可获得的乐趣。
Memory tip: Think of 'cost' as what you 'lost' — the next best thing lost.
记忆技巧：将“成本”看作你“失去”的东西——失去的次优之物。
6. Demand and Supply | 需求与供给
Demand is the quantity of a good or service that consumers are willing and able to buy at different prices. Supply is the quantity that producers are willing and able to sell. The law of demand states that as price rises, quantity demanded falls. The law of supply states that as price rises, quantity supplied rises.
需求是指在不同价格水平下，消费者愿意并且能够购买的商品或服务的数量。供给是指生产者愿意并且能够出售的数量。需求定律指出，价格上升时，需求量下降。供给定律指出，价格上升时，供给量上升。
Memory tip: Draw arrows — ly up. Imagine a seesaw: on the demand side, price and quantity move opposite directions; on the supply side, they move together.
记忆技巧：画箭头——价格上升 → 需求下降；价格上升 → 供给上升。想象跷跷板：需求一端价格与数量反向移动；供给一端同向移动。
7. Markets and Prices | 市场与价格
A market is any arrangement that brings buyers and sellers together to exchange goods or services. The price is determined by the interaction of demand and supply. The equilibrium price is where quantity demanded equals quantity supplied. Markets can be physical (like a farmers' market) or online.
市场是使买方和卖方聚集在一起交换商品或服务的任何安排。价格由需求与供给的相互作用决定。均衡价格是需求量等于供给量时的价格。市场可以是有形的（如农贸市场）或在线的。
Memory tip: Picture a market stall: supply meets demand; where they meet is the price tag.
记忆技巧：想象一个市场摊位：供给碰到需求；它们相遇之处就是价格标签。
8. Consumers and Producers | 消费者与生产者
Consumers are individuals or households that buy goods and services for personal use. Producers are businesses that make goods or provide services. The aim of consumers is to maximise satisfaction (utility), while producers aim to maximise profits. Their interaction drives the economy.
消费者是购买商品和服务用于个人使用的个人或家庭。生产者是制造商品或提供服务的企业。消费者的目标是最大化满足感（效用），而生产者的目标是利润最大化。他们的互动推动着经济。
Memory tip: 'Consumer' starts with 'con' like 'consume'; 'Producer' like 'produce'. Think: producers make, consumers take.
记忆技巧：“消费者”像“消费”；“生产者”像“生产”。想象：生产者制造，消费者取用。
9. Specialisation and Trade | 专业化与贸易
Specialisation occurs when individuals, businesses, or countries focus on producing a limited range of goods or services to become more efficient. Trade then allows them to exchange their surplus for other goods they need. This leads to higher total output and benefits all parties. The division of labour is a form of specialisation where workers focus on specific tasks.
专业化是指个人、企业或国家专注于生产有限范围的商品或服务以提高效率。然后通过贸易，它们可以用剩余产品换取所需的其他商品。这会提高总产出，使各方受益。劳动分工是一种专业化形式，工人们专注于特定任务。
Memory tip: Think of a pizza restaurant: one person makes dough, another adds toppings — they specialise and produce faster together, then trade with other businesses for ingredients.
记忆技巧：想象一家比萨店：一个人做面团，另一个人加配料——他们通过专业化更高产地合作，然后通过贸易获取原料。
10. Money and Barter | 货币与物物交换
Barter is the direct exchange of goods and services without using money. It requires a double coincidence of wants, meaning both traders must want what the other offers. Money solves this problem by acting as a medium of exchange, a store of value, and a unit of account. Modern economies use money to facilitate trade efficiently.
物物交换是不使用货币而直接交换商品和服务。它需要“欲望的双重巧合”，即双方必须同时想要对方提供的物品。货币通过充当交换媒介、价值储藏和计价单位解决了这个问题。现代经济使用货币来有效促进贸易。
Memory tip: Remember the three functions of money: 'M.A.S.' — Medium of exchange, A store of value, Standard of deferred payment (or Unit of account). Alternatively, 'Money Eliminates the Double Coincidence'.
记忆技巧：记住货币的三个功能：“M.A.S.”——交换媒介、价值储藏、计价标准（或延迟支付标准）。或者“货币消除了双重巧合”。
11. Economic Systems | 经济体系
An economic system is the way a society organises the production, distribution, and consumption of goods and services. The main types are market economy (decisions made by individuals and firms), command economy (government makes decisions), and mixed economy (a combination). Most real-world economies are mixed, combining elements of both markets and government intervention.
经济体系是一个社会组织商品和服务的生产、分配和消费的方式。主要类型包括市场经济（由个人和企业决策）、计划经济（政府决策）和混合经济（两者结合）。大多数现实经济是混合型，结合了市场和政府干预的元素。
Memory tip: Imagine a school canteen: if students decide what to serve based on votes, that's a market; if the head teacher decides the menu entirely, that's a command; if a committee of students and teachers decides together, it's mixed.
记忆技巧：想象学校食堂：如果学生根据投票决定供应什么，那是市场；如果校长完全决定菜单，那是命令；如果学生和老师组成的委员会共同决定，那是混合。
12. Cost, Revenue and Profit | 成本、收入与利润
income a business earns from selling its products (Price × Quantity sold). Profit is the difference between total revenue and total cost. If costs exceed revenue, the business makes a loss.
成本是生产商品或服务所产生的费用，包括固定成本（租金、工资）和可变成本（原材料）。收入是企业从销售产品中获得的收益（价格 × 销售量）。利润是总收入与总成本之间的差额。如果成本超过收入，企业就会亏损。
Memory tip: Remember 'Profit is what's left after Cost eats from Revenue'. Or the formula: Profit = Total Revenue – Total Cost.
记忆技巧：记住“利润是收入被成本吃掉后剩下的”。或公式：利润 = 总收入 – 总成本。
