📚 A-Level Economics: A Guide to Clear and Effective Writing | A-Level经济：清晰高效写作技巧指南

Many A-Level Economics students lose marks not because they misunderstand concepts, but because they cannot communicate their understanding clearly. This guide provides practical writing strategies for CIE A-Level Economics: interpreting command words, structuring answers, using diagrams, and evaluating, so you can write essays and data-response answers that earn full marks.

很多A-Level经济学生在概念上并没有问题，却因为表达不清而丢分。本文针对CIE A-Level经济，提供实用的写作策略：理解指令词、组织答案结构、使用图表和进行评估，帮助你在论文和数据响应题中获得满分。

1. Understand Command Words Before You Write | 1. 动笔前先理解指令词

The first step to clear writing is knowing exactly what the question asks. CIE uses specific command words, and each demands a different level of response. Answering an ‘evaluate’ question with description is a common source of lost marks.

清晰写作的第一步是准确理解题目要求。CIE使用特定的指令词，每一种指令词要求不同层次的回答。用描述性语言回答“评估”类题目是常见的失分原因。

For example, if a question says ‘Analyse how a depreciation of the exchange rate affects the current account’, you must build a chain: depreciation makes exports cheaper and imports dearer, so net exports may rise, provided elasticities are favourable. That is analysis, not evaluation.

例如，如果题目要求“分析汇率贬值如何影响经常账户”，你需要构建因果链：贬值使出口更便宜、进口更昂贵，因此在弹性有利的情况下净出口可能上升。这是分析，而不是评估。

2. Use a Logical Structure: Introduction, Analysis, Evaluation, Conclusion | 2. 采用逻辑结构：引言、分析、评估、结论

A clear essay is built on a clear skeleton. For a 20-mark CIE Economics essay, use five stages: a short introduction that interprets the question, precise definitions of key terms, analysis using diagrams and logical chains, evaluation, and a conclusion that directly answers the question. The conclusion should not simply repeat the introduction; it should weigh the arguments you have made.

清晰的论文建立在清晰的骨架之上。对于CIE经济的20分论文，可使用五个阶段：简短引言以解读题目，精确定义关键术语，用图表和逻辑链进行分析，进行评估，以及直接回答题目的结论。结论不应只是重复引言，而应对全文论点作出权衡。

In the introduction, rephrase the question in your own words and set out the scope of your answer. If the question is about market failure, say whether you will focus on externalities, public goods or information failure. This tells the examiner that you have understood the question and helps you avoid wandering off-topic.

在引言中，用自己的话转述题目，并设定回答范围。如果题目关于市场失灵，说明你主要讨论外部性、公共物品还是信息失灵。这能让考官知道你理解了题目，并帮助你避免偏题。

Every paragraph should have one main point. Start with that point, then support it with economic theory, a diagram or a real-world example. End the paragraph with a sentence that links back to the question. This creates coherence and makes it easy for the examiner to give you credit.

每个段落应只有一个主要观点。先提出观点，然后用经济理论、图表或现实案例支持，最后用一句话回扣题目。这样的段落结构具有连贯性，也方便考官给你打分。

3. Use Precise Economic Terminology and Definitions | 3. 使用精确的经济术语和定义

Economics rewards precise vocabulary. Always define or correctly use terms such as opportunity cost, marginal utility, ceteris paribus, price elasticity of demand, externalities, and positive and normative statements. Avoid saying ‘demand goes up’ when you mean ‘quantity demanded rises’. The distinction is important: a change in price causes a movement along the demand curve, while a change in a non-price determinant causes a shift of the whole curve.

经济学科重视精确的词汇。始终定义或正确使用机会成本、边际效用、假设其他条件不变、需求价格弹性、外部性以及实证陈述和规范陈述等术语。避免在“需求量增加”时笼统说“需求上升”。这个区别很重要：价格变化引起需求曲线上的移动，而非价格因素的变化使整条曲线移动。

For key formulas, write them out clearly. For example:

对于关键公式，要清楚写出。例如：

PED = (% change in quantity demanded) ÷ (% change in price)

Use ‘elastic’ and ‘inelastic’ carefully, and always identify whether you are talking about price elasticity, income elasticity or cross-elasticity. If you use a term such as ‘multiplier’, define it as the ratio of a change in equilibrium output to the initial injection. Precise definitions give you marks before you even begin your analysis.

要谨慎使用“富有弹性”和“缺乏弹性”，并明确你讨论的是价格弹性、收入弹性还是交叉弹性。如果使用“乘数”，应将其定义为均衡产出变动与初始注入量之比。精确的定义在分析尚未开始前就能为你赢得分数。

4. Integrate Diagrams Effectively | 4. 有效整合图表

Diagrams are a compact way to show economic logic. A properly labelled diagram can earn several marks, but an unlabelled or unexplained diagram earns nothing. Every diagram must have labelled axes and curves. When a curve shifts, draw an arrow and write a sentence about the cause of the shift. Then refer to the diagram in your answer: ‘As shown in the diagram, a rise in costs shifts the supply curve from S₁ to S₂, causing the equilibrium price to rise from P₁ to P₂ and the equilibrium quantity to fall from Q₁ to Q₂.’

图表是展示经济逻辑的紧凑方式。一张标注得当的图可以拿到几分，但无标注或不解释的图拿不到分。每张图必须有标注的坐标轴和曲线。当曲线移动时，画出箭头并写一句说明移动原因。然后在答案中引用图表：“如图所示，成本上升使供给曲线从S₁移动到S₂，导致均衡价格从P₁上升到P₂，均衡数量从Q₁下降到Q₂。”

Choose the diagram that exactly matches your analysis. In macroeconomics, use an AD/AS diagram for inflation, growth or unemployment. In microeconomics, use supply and demand diagrams for price controls, taxes, subsidies and externalities. Do not draw two diagrams when one is enough, and never leave a diagram without explaining what it proves.

选择与你的分析完全匹配的图表。宏观经济学中，分析通胀、增长或失业时使用AD/AS图。微观经济学中，分析价格管制、税收、补贴和外部性时使用供求图。不要画两个多余的图，也绝不要画完图却不解释它证明了什么。

5. Match Time Horizons and Economic Frameworks | 5. 匹配时间范围和经济框架

The correct framework depends on the question. For microeconomic questions, think about demand and supply, elasticities, costs and revenue, market structure, and market failure. For macroeconomic questions, think about aggregate demand and aggregate supply, fiscal and monetary policy, economic growth, inflation, unemployment and the current account. If you use the wrong framework, even a well-written answer will not receive high marks.

正确的框架取决于题目。微观题目需要考虑供求、弹性、成本与收益、市场结构和市场失灵。宏观题目需要考虑总需求与总供给、财政与货币政策、经济增长、通胀、失业以及经常账户。如果框架错误，即使文章写得再好，也难以获得高分。

Always specify the time horizon.
