📚 Year 7 CCEA Economics: Interdisciplinary Question Practice | 跨学科综合题型训练

Welcome to this revision guide designed to help you tackle the interdisciplinary question styles you often meet in Year 7 CCEA Economics. In today’s classroom, economics is not studied in isolation – it links with maths, geography, history, science, and even English. This article provides you with practical examples and tips to build your confidence when solving mixed-subject questions.

欢迎阅读这份复习指南，它将帮助你应对Year 7 CCEA经济课程中常见的跨学科题型。如今在课堂上，经济学并非孤立学习——它与数学、地理、历史、科学甚至英语都有联系。本文通过实用的例子和建议，帮助你增强解决跨学科混合题型的信心。

1. Why Interdisciplinary Skills Matter in Economics | 为什么经济学需要跨学科技能

Economics is the study of how people make choices to satisfy their needs and wants with limited resources. To understand these choices fully, you often need to use skills from other subjects. For example, you might need to calculate how much a family can spend (maths), identify where resources come from (geography), or explain how money has changed over time (history). When you face a question that mixes topics, stay calm – you already have the tools to solve it.

经济学研究人们如何用有限的资源做出选择以满足需求和欲望。要全面理解这些选择，往往需要用到其他学科技能。例如，你可能需要计算一个家庭的支出能力（数学），确定资源的来源（地理），或者解释货币随时间的变化（历史）。当你遇到混合多学科内容的题目时，保持冷静——你已经拥有解决问题的工具。

2. Maths in Economics: Calculating Costs and Percentages | 经济学中的数学：计算成本与百分比

Many economics questions ask you to work with numbers. You might see price lists, discounts, or total costs. Let’s practise a typical example.

许多经济题要求你处理数字。你可能会看到价目表、折扣或总成本。让我们练习一个典型例子。

Example: A school tuck shop sells fruit. An apple costs £0.40, a banana costs £0.35, and a carton of juice costs £0.80. If Jamie buys two apples, one banana and two juices, how much does he spend in total? He pays with a £5 note. Calculate his change.

例题：学校小吃部出售水果。一个苹果£0.40，一根香蕉£0.35，一盒果汁£0.80。如果Jamie买了两个苹果、一根香蕉和两盒果汁，他一共花费多少？他用一张£5纸币支付，请计算找零。

Solution: Cost of apples: 2 × £0.40 = £0.80. Cost of banana: £0.35. Cost of juices: 2 × £0.80 = £1.60. Total = £0.80 + £0.35 + £1.60 = £2.75. Change from £5: £5.00 − £2.75 = £2.25. Notice how basic arithmetic helps us understand spending decisions.

解答：苹果花费：2 × £0.40 = £0.80。香蕉：£0.35。果汁：2 × £0.80 = £1.60。总计 = £0.80 + £0.35 + £1.60 = £2.75
