1. Scarcity and the Economic Problem | 稀缺性与经济问题
Many past paper questions start with the basic economic problem: unlimited wants versus limited resources. A typical question might ask: 'Define the economic problem.' The model answer should mention that resources (land, labour, capital, enterprise) are scarce, forcing society to make choices. In data-response tasks, you may be given a resource allocation scenario and asked to identify the opportunity cost of a decision.
历年真题常常从基本经济问题入手：无限欲望与有限资源之间的矛盾。常见问题如：“定义经济问题。”标准答案需要指出资源（土地、劳动、资本、企业家才能）是稀缺的，迫使社会做出选择。在数据分析题中，你可能需分析资源配置情景，并指出决策的机会成本。
When answering 'Explain why scarcity exists', students must avoid simply stating 'because resources are limited'. Instead, link to the idea that human wants are infinite while productive resources are finite. Edexcel mark schemes reward clear cause-and-effect reasoning: scarcity leads to choice, and choice involves an opportunity cost.
回答“解释稀缺性为何存在”时，学生们要避免仅仅说“因为资源有限”。应该联系到人类欲望无限而生产资源有限这一事实。Edexcel 评分标准奖励清晰的因果关系推理：稀缺导致选择，而选择涉及机会成本。
| Command Word | Meaning | 指令词 | 含义 |
|---|---|---|---|
| Define | Give the precise meaning of a term | 定义 | 给出术语的确切含义 |
| Explain | Set out causes or reasons | 解释 | 阐述原因或理由 |
2. Factors of Production and Opportunity Cost | 生产要素与机会成本
Past papers frequently ask students to list the four factors of production and give examples. A strong response for 'Identify two factors of production used by a bakery' would state 'labour (bakers) and capital (ovens)'. Always remember enterprise is the risk-taking factor that organises the other three. In higher-mark questions, you may need to explain how a change in technology affects the productivity of capital.
历年试卷频繁要求学生列出四种生产要素并举例。对于“指出面包店使用的两种生产要素”，有力答案是“劳动（面包师）和资本（烤炉）”。务必记住企业家才能是承担风险、组织其他三要素的要素。在高分题目中，你可能需要
