Main Teaching Activities and Time Allocation 主要教学活动和时间分配
Review and Topic Introduction: Briefly checked on previous work and introduced the new topic: actual and potential economic growth and the output gap based on student request.
回顾与主题介绍： 根据学生要求，简要回顾了先前内容并引入了新主题：实际与潜在经济增长和产出缺口。
Defining Output Gap Components: Detailed explanation and clarification of 'actual output' (Real GDP) and 'potential output' (maximum sustainable level using all resources, related to the PPF). Used numerical examples to calculate the output gap.
定义产出缺口要素： 详细解释和澄清了‘实际产出’（实际GDP）和‘潜在产出’（利用所有资源的最大可持续水平，与PPF相关）。使用数字示例计算了产出缺口。
Types of Output Gaps: Explained negative output gap (Actual < Potential), zero output gap (Actual = Potential), and positive output gap (Actual > Potential, indicating overheating), linking them to economic conditions like recessions.
产出缺口的类型： 解释了负产出缺口（实际<潜在）、零产出缺口（实际=潜在）和正产出缺口（实际>潜在，表明经济过热），并将其与衰退等经济状况联系起来。
Growth vs. Output Gap Distinction: Clarified the difference between economic 'growth' (speed/rate of increase in GDP) and 'output gap' (a stock/value difference at a point in time), specifically defining potential vs. actual economic growth.
增长与产出缺口的区分： 澄清了经济‘增长’（GDP增加的速度/速率）与‘产出缺口’（某一时刻的存量/价值差异）的区别，特别是定义了潜在经济增长与实际经济增长。
Exam Question Practice on Negative Output Gap: Worked through exam questions requiring the illustration and explanation of a negative output gap using diagrams (PPF-based and Real GDP/Time trend lines) and referencing provided data (2008-2009 crisis).
负产出缺口模拟考试练习： 练习了要求使用图表（基于PPF和实际GDP/时间趋势线）并参考提供数据（2008-2009年危机）来阐述和解释负产出缺口的考试题。
