要掌握 Year 7 AQA 经济学，仅靠记住定义是不够的。考官看重的是清晰的解释、将概念应用到实际案例中的能力，以及准确使用经济学术语。本文拆解了真实的历年真题，给出标准答案并深入剖析评分规则。读完之后，你会清楚地知道考试要求以及如何避开最常见的失分陷阱。
1. The Basic Economic Problem | 基本经济问题
Question: 'Define the basic economic problem.' (2 marks)
真题：“定义基本经济问题。”（2分）
Model answer: The basic economic problem arises because resources are scarce while human wants are virtually unlimited. This mismatch forces individuals and governments to make choices about how best to allocate those limited resources.
标准答案：基本经济问题的产生是因为资源是稀缺的，而人类的需求几乎是无限的。这种不匹配迫使个人和政府必须就如何最优地分配有限资源做出选择。
Examiner insight: Full marks require both 'scarcity' and 'unlimited wants' to be clearly stated. Simply writing 'not enough resources' is too vague—you must explicitly link the problem to the need for choice. Top-scoring scripts often add a brief example, such as 'a student must choose between buying a textbook and a cinema ticket'.
考官点评：要拿满分，必须清晰陈述“稀缺性”和“无限欲望”。仅仅写“资源不够”过于模糊——你必须明确将这个问题与选择的必要性联系起来。高分答卷通常会补充一个简短例子，比如“一个学生必须在买课本和电影票之间做出选择”。
2. Opportunity Cost in Exam Questions | 机会成本考点解析
Question: 'Using an example, explain the concept of opportunity cost.' (3 marks)
真题：“用一个例子解释机会成本的概念。”（3分）
Model answer: Opportunity cost is the next best alternative given up when a choice is made. For example, if a baker uses her last bag of flour to bake bread rather than cakes, the opportunity cost is the profit she could have earned from selling the cakes.
标准答案：机会成本是做出选择时放弃的次优替代品。例如，如果一位面包师用最后一袋面粉烤面包而不是烤蛋糕，那么机会成本就是她本可以通过卖蛋糕赚到的利润。
Common mistake: Candidates often describe the cost in money terms only, forgetting that opportunity cost is about the benefit lost, not the cash spent. The definition must include 'next best alternative forgone'. Always pair the chosen option with the specific sacrificed option in your example.
常见错误：考生往往只用金钱来描述成本，忘记了机会成本关乎的是放弃的收益，而非花掉的钱。定义中必须包含“放弃的次优替代品”。在你的例子中，务必把被选中的选项和被牺牲的特定选项对应起来。
3. Factors of Production | 生产要素
Question: 'Identify the four factors of production and give an example of each.' (4 marks)
真题：“列出四种生产要素，并各举一例。”（4分）
Model answer: Land includes all natural resources, e.g. a river used for irrigation. Labour is human effort, e.g. a teacher delivering a lesson. Capital means man-made goods used to produce other goods, e.g. a tractor. Enterprise is the willingness to take risks and organise the other three factors, e.g. an entrepreneur starting a new restaurant.
标准答案：土地包括所有自然资源，例如用于灌溉的河流。劳动指人类的努力，例如教师授课。资本指用于生产其他商品的人造物品，例如拖拉机。企业家精神指承担风险并组织其他三种要素的意愿，例如创业者开办新餐厅。
Top tip: AQA marks reward precision. 'Capital' must not be confused with money; it is physical capital. Enterprise needs a description of risk-taking and innovation, not just 'the boss'. Use specific, labelled examples to secure all 4 marks.
高分技巧：AQA 的评分奖励精确性。“资本”决不能与金钱混淆；它指的是实物资本。企业家精神需要描述风险承担和创新，而不只是“老板”。用带标签的具体例子来确保拿下全部分数。
4. Shifting the Demand Curve | 需求曲线的移动
Question: 'State two factors that could cause the demand for streaming services to increase. Illustrate the effect on a demand curve.' (4 marks)
真题：“说出两个可能导致流媒体服务需求增加的因素，并在需求曲线上展示其影响。”（4分）
Model answer: An increase in consumer income (assuming streaming is a normal good) and a successful advertising campaign can raise demand. On the diagram, the entire demand curve shifts to the right, from D₁ to D₂. This means at every price level, a larger quantity is demanded.
标准答案：消费者收入增加（假设流媒体是正常商品）和成功的广告宣传活动可以提高需求。在图表上，整条需求曲线向右移动，从 D₁ 移到 D₂。这意味着在每一个价格水平上，需求量都变得更大。
Diagram analysis: AQA expects a correctly labelled graph—price on vertical axis, quantity on horizontal, original and new demand curves clearly marked. Avoid shifting along the same curve; that would be a change in quantity demanded, not a change in demand itself. Use arrows and label them 'D₁' and 'D₂'.
图表分析：AQA 要求正确标记的图表——纵轴为价格，横轴为数量，原始需求曲线和新的需求曲线清晰标明。要避免沿同一条曲线移动，因为那代表的是需求量的变动，而不是需求本身的变动。使用箭头并标记为“D₁”和“D₂”。
5. Supply and Production Costs | 供给与生产成本
Question: 'Explain how a rise in raw material prices is likely to affect the supply of furniture.' (3 marks)
真题：“解释原材料价格上涨可能如何影响家具的供给。”（3分）
Model answer: Higher raw material prices increase the cost of production. At each price, firms are less willing and able to supply the same quantity, so the supply curve shifts to the left. This means a contraction in supply, and the equilibrium market quantity will fall.
标准答案：原材料价格上涨会增加生产成本。在每个价格水平上，企业愿意并能够供应的数量都会减少，因此供给曲线向左移动。这意味着供给收缩，市场均衡数量将会下降。
ame logic applies to technology improvements which shift supply to the right. Connecting steps earns 'analysis' marks.
应试技巧：采用因果链：原因（成本上升）→ 对利润率的影响 → 对生产意愿的影响 → 供给曲线移动。同理，技术进步会将供给曲线向右移动。把这些步骤串联起来就能拿到“分析”分。
6. Market Equilibrium and Price Adjustments | 市场均衡与价格调整
Question: 'The market for train tickets is initially in equilibrium. Then a new low-cost airline enters the same route. Analyse the effect on the equilibrium price and quantity of train tickets.' (5 marks)
真题：“火车票市场最初处于均衡状态。随后一家新的低成本航空公司进入同一航线。分析这对火车票的均衡价格和数量的影响。”（5分）
Model answer: The airline offers a substitute for train travel, so demand for train tickets decreases (shifts left). With unchanged supply, this creates a surplus at the original price. The price of train tickets will fall as firms cut prices to clear the surplus, and the equilibrium quantity will also decrease.
标准答案：航空公司提供了火车的替代出行方式，因此对火车票的需求减少（需求曲线向左移动）。供给不变时，这会在原价格处造成过剩。火车票价格会下跌，因为公司会为清空过剩而降价，均衡数量也会减少。
Linking to diagram: Draw initial equilibrium E₁. Then shift demand left to D₂. Mark new equilibrium E₂ with lower P and lower Q. Label axes, curves, and equilibrium points. AQA deductions come from missing labels or failing to state the direction of price and quantity movement.
关联图表：画出初始均衡点 E₁。然后将需求曲线向左移至 D₂。标出新均衡点 E₂，具有更低的价格 P 和更少的数量 Q。标记坐标轴、曲线和均衡点。AQA 的扣分点在于漏标或没有明确价格与数量的变动方向。
7. Functions of Money | 货币的职能
Question: 'Identify and explain three functions of money. Use examples.' (6 marks)
真题：“指出并解释货币的三种职能，并用例子说明。”（6分）
Model answer: Medium of exchange—money is accepted as payment for goods and services, e.g. using coins to buy a snack. Store of value—money can be saved and used later, e.g. keeping cash in a piggy bank. Unit of account—money provides a common measure of value, e.g. a laptop is priced at £400, making comparison easy.
标准答案：交易媒介——货币被接受为商品和服务的支付手段，例如用硬币买零食。价值贮藏——货币可以储存起来以后再用，例如把钱存放在储蓄罐里。记账单位——货币提供了一个通用的价值衡量标准，例如一台笔记本电脑标价400英镑，使比较变得容易。
Elaboration for higher marks: For 'store of value', mention that inflation can erode it. For 'unit of account', contrast with barter where values must be negotiated for every trade. Connecting functions to the problems of a barter economy shows deeper understanding.
高分阐述：对于“价值贮藏”，可以提及通货膨胀会侵蚀其价值。对于“记账单位”，可以与物物交换对比，后者每次交易都需要协商价值。将货币职能与物物交换经济的问题联系起来能展现更深的理解。
8. Specialisation and Division of Labour | 专业化与分工
Question: 'Explain one advantage and one disadvantage of specialisation for a business.' (4 marks)
真题：“解释专业化对企业的优点和缺点各一个。”（4分）
Model answer: An advantage is increased productivity; workers become faster and more skilled at a specific task, lowering average costs. A disadvantage is boredom—repetitive tasks may reduce worker motivation and could lead to higher staff turnover.
标准答案：一个优点是提高生产率；工人在特定任务上变得更熟练、更快速，从而降低平均成本。一个缺点是枯燥——重复性的任务可能降低工人的积极性，并可能导致更高的员工流失率。
Balance is key: AQA often asks for 'one advantage and one disadvantage'—you need to structure two separate, developed paragraphs. Each must clearly state the point, explain why it happens, and link to a business outcome. Avoid listing points without explanation.
均衡是关键：AQA 常考“一个优点和一个缺点”——你需要写出两个独立且展开充分的段落。每段必须清晰陈述观点，解释其发生原因，并联系企业结果。避免只列要点而不解释。
9. Primary, Secondary and Tertiary Sectors | 第一、第二和第三产业
Question: 'Define the three main economic sectors and give an example of a job in each. Then explain one reason why the tertiary sector might grow as a country develops.' (6 marks)
真题：“定义三大经济部门，并各举一个职业例子。然后解释随着国家发展，第三产业为什么会增长的一个原因。”（6分）
Model answer: Primary sector extracts raw materials, e.g. fisherman. Secondary sector manufactures goods, e.g. car assembly worker. Tertiary sector provides services, e.g. nurse. As incomes rise, demand shifts from basic goods towards services like tourism and education, so more workers are needed in the tertiary sector.
标准答案：第一产业开采原材料，例如渔民。第二产业制造商品，例如汽车装配工。第三产业提供服务，例如护士。随着收入增加，需求从基本商品转向旅游、教育等服务，因此第三产业需要更多劳动力。
Enrich your answer: Use data if given, such as 'the tertiary sector now accounts for over 70% of UK employment'. Also mention other reasons: mechanisation in primary and secondary sectors reduces labour needs, leading to structural unemployment and a shift by workers into services.
丰富你的答案：如果题目提供了数据，要加以引用，比如“第三产业现在占英国就业的70%以上”。也可以提及其他原因：第一和第二产业的机械化减少了劳动力需求，导致结构性失业，工人向服务业转移。
10. Mixed Economy and Government Intervention | 混合经济与政府干预
Question: 'Explain why most economies are mixed economies rather than pure market or pure command systems.' (4 marks)
真题：“解释为什么大多数经济体是混合经济，而不是纯粹市场经济或纯粹计划经济。”（4分）
Model answer: A pure market economy may fail to provide public goods like street lighting and could lead to extreme inequality. A pure command economy often lacks efficiency and innovation because there is no profit incentive. Mixed economies combine the market's responsiveness with government intervention to correct market failures and ensure a safety net.
标准答案：纯粹市场经济可能无法提供像路灯这样的公共品，并可能导致极端不平等。纯粹计划经济通常缺乏效率和创新，因为没有利润激励。混合经济融合了市场的灵敏性与政府干预，以纠正市场失灵并提供安全网。
Application tip: Refer to real-world contexts—the UK is mixed because while most decisions are made by private firms, the government provides healthcare and regulates monopolies. Mentioning specific roles of the government, such as taxation and subsidies, strengthens your response.
应用技巧：联系现实情境——英国是混合经济，因为虽然大部分决策由私营企业做出，但政府提供医疗保健并管制垄断。提及政府的具体角色，如税收和补贴，能增强你的回答。
11. Handling 'Analyse' Questions: A Step-by-Step Method | “分析”题解题步骤
Question: 'Analyse how an increase in the minimum wage might affect a local fast-food restaurant.' (6 marks)
真题：“分析最低工资提高可能会如何影响一家本地快餐店。”（6分）
Model answer: An increased minimum wage raises the restaurant's labour costs. This might reduce profit margins, possibly forcing the owner to raise menu prices. Higher prices could cause some customers to switch to competitors, reducing revenue. However, the higher wage could also motivate workers to be more productive, partly offsetting the cost increase. Overall, employment levels at the restaurant may fall if the cost pressure is too high.
标准答案：最低工资提高会增加快餐店的劳动力成本。这可能会减少利润率，可能迫使店主提高菜单价格。更高的价格会导致部分顾客转向竞争对手，减少收入。然而，更高的工资也可能激励工人提高生产率，部分抵消成本上涨。总体而言，如果成本压力过大，快餐店的雇佣水平可能会下降。
Structure for success: Start with the direct impact, then trace the knock-on effects. Use connectives like 'this leads to...' and 'as a result...'. A two-sided analysis ('on the one hand... on the other hand...') earns the highest marks, especially when you finish with a reasoned judgement on the net effect.
成功结构：从直接影响开始，然后追踪连锁反应。使用“这导致...”、“因此...”等连接词。两面分析（“一方面...另一方面...”）能获得最高分数，尤其是在最后给出关于净影响的理性判断时。
12. Exam-Winning Terminology & Final Tips | 夺分术语与终极建议
Question: Many marks are lost because students use everyday language where economic terms are required. For instance, instead of 'when the price goes up, people buy less', write 'as price increases, quantity demanded contracts, showing the law of demand'.
真题趋势：许多失分是由于学生在需要使用经济术语时用了日常用语。例如，不要把“价格上涨，人们买的少”写成口语，而应写为“价格上升，需求量收缩，这体现了需求定律”。
Key terms to master: Scarcity, opportunity cost, factors of production, demand, supply, equilibrium, elasticity (basic concept), public good, merit good, fiscal policy (introductory). Practice using them naturally in sentences. When you revise past papers, highlight the terminology in the mark scheme and check if your own answer uses those exact words.
需掌握的关键术语：稀缺性、机会成本、生产要素、需求、供给、均衡、弹性（基础概念）、公共品、优值品、财政政策（入门）。练习在句子中自然地使用它们。复习真题时，将评分方案中的术语高亮，并检查自己的答案中是否用到了完全相同的措辞。
Final exam tip: Always allocate time based on marks—a 4-mark question deserves about 4 minutes of writing. Keep diagrams neat, label them fully, and never leave a question blank. A reasoned attempt, even if incomplete, can pick up partial marks that make the difference on grade boundaries.
终极考试建议：始终根据分值分配时间——一个4分的题目大约应花4分钟写答案。图表要整洁，完整标记，绝不要空题。一个有理有据的尝试，即使不完整，也能得到部分分数，而这往往是在等级线上决定胜负的关键。
