Use this table as a checklist when you progress through the PDF. Tick each unit only when you can define every key term and draw every required diagram.
请将上表作为学习清单。只有当你能够定义每一个关键术语并画出每一个必备图表时，才勾选该单元。
3. The Basic Economic Problem | 基本经济问题
The coursebook opens with scarcity: unlimited wants against limited resources. This creates choice and opportunity cost, the value of the next best alternative forgone.
教材首先讲解稀缺性：无限的欲望与有限的资源。这便产生了选择与机会成本，即所放弃的次优选择的价值。
Opportunity cost = value of next best alternative sacrificed
You must be able to apply opportunity cost to consumers, workers, producers, and governments. Exam questions often ask you to identify what is given up in a decision.
你必须能够将机会成本应用于消费者、工人、生产者和政府。考题常要求你指出某个决策放弃了什么。
4. Demand, Supply and Market Equilibrium | 需求、供给与市场均衡
This section is the foundation of microeconomics. The coursebook uses demand and supply diagrams to show how equilibrium price and quantity are determined. Remember: a price change causes a movement along the curve, while other factors shift the entire curve.
这一部分是微观经济学的基础。教材通过需求与供给曲线图说明均衡价格与数量如何决定。请记住：价格变化引起沿曲线的移动，而其他因素会使整条曲线移动。
Key formulas include price elasticity of demand and supply:
