📚 Interdisciplinary Question Training for Year 7 AQA Economics | 跨学科综合题型训练
This article helps Year 7 students master AQA Economics by tackling cross-curricular questions that blend economics with maths, geography, history, and science. Through worked examples and step-by-step solutions, you will learn how to apply economic concepts to real-world and multi-subject problems.
本文通过跨学科综合题型训练，帮助七年级学生掌握 AQA 经济学知识，将经济学与数学、地理、历史和科学相融合。借助例题与分步解析，你将学会如何运用经济概念解决现实世界中的多学科问题。
1. Maths and Money: Budgeting and Percentage Calculations | 数学与金钱：预算与百分比计算
Economics often requires basic maths. A typical question might ask you to manage a budget, calculate percentage discounts, or work out unit costs. Let’s look at an example.
经济学常常需要基础数学。典型题目可能要求你管理预算、计算折扣百分比或计算单价。我们来看一个例子。
Example: Sara has a weekly allowance of £10. She wants to buy snacks for a school trip. Crisps cost £0.70 per pack, juice costs £1.20 per box, and chocolate bars cost £0.90 each. She must buy at least 2 of each item. What is the maximum number of chocolate bars she can afford if she buys exactly 2 packs of crisps and 2 boxes of juice?
例题：Sara 每周零花钱是10英镑。她想为学校旅行买零食。薯片每包0.70英镑，果汁每盒1.20英镑，巧克力每块0.90英镑。她每样至少买2个。如果她刚好买2包薯片和2盒果汁，她最多还能买多少块巧克力？
Solution: Calculate the cost of 2 crisps: 2 × 0.70 = 1.40. 2 juices: 2 × 1.20 = 2.40. Total so far: 1.40 + 2.40 = 3.80. Remaining money: 10 − 3.80 = 6.20. Divide by the price of a chocolate bar: 6.20 ÷ 0.90 ≈ 6.88, so she can afford 6 full chocolate bars (not 7, as that would cost 6.30 which is over 6.20). Answer: 6 chocolate bars.
解答：计算2包薯片的花费：2 × 0.70 = 1.40 英镑。2盒果汁：2 × 1.20 = 2.40 英镑。目前总花费：1.40 + 2.40 = 3.80 英镑。剩余金额：10 − 3.80 = 6.20 英镑。除以巧克力单价：6.20 ÷ 0.90 ≈ 6.88，所以她能买6块整块巧克力（不能买7块，因为7 × 0.90 = 6.30 超过6.20）。答案：6块巧克力。
This type of question combines arithmetic with the economic idea of a budget constraint – a fundamental concept in Year 7 economics.
这种题型将算术与经济学的预算约束概念结合，这是七年级经济学的一个基本概念。
2. Geography and Resources: Where Do Goods Come From? | 地理与资源：商品从何而来？
Cross-curricular questions often link economics to geography by showing how natural resources determine what a country produces. For example, a country with fertile soil may specialise in agriculture, while a country with oil reserves may export petroleum.
跨学科题目常将经济学与地理学联系起来，展示自然资源如何决定一个国家的生产。例如，土壤肥沃的国家可能专门从事农业，而拥有石油储备的国家可能出口石油。
Example: Read the description: Country X has a warm climate, lots of flat land, and plenty of rain. Country Y has cold winters, steep mountains, and rich mineral deposits. Which country is more likely to export tropical fruits? Explain your answer using economic terms like ‘specialisation’ and ‘comparative advantage’.
例题：阅读描述：X国气候温暖，拥有大量平坦土地和充沛降雨。Y国冬季寒冷，山势陡峭，矿物资源丰富。哪个国家更可能出口热带水果？请用’专业化’和’比较优势’等经济术语解释你的答案。
Sample answer: Country X can produce tropical fruits more efficiently due to its favourable climate and fertile flat land. It has a comparative advantage in fruit production. Therefore, it should specialise in growing fruits and export them. Country Y is better suited to mining, so it specialises in mineral extraction.
参考回答：X国由于气候适宜和土地平坦肥沃，能更高效地生产热带水果，它在水果生产上具有比较优势。因此，它应专业化种植水果并出口。Y国更适合采矿，所以它专业化开采矿物。
3. History: From Barter to Banknotes | 历史：从以物易物到纸币
Understanding how money evolved helps us see why paper money has value. A history-based economics question might ask you to explain the problems of barter and how money solved them.
了解货币的演变有助于我们明白纸币为何有价值。基于历史的经济学题目可能会让你解释以物易物的问题以及货币如何解决这些问题。
Example: In Ancient Egypt, people often exchanged goods directly. If a farmer wanted a pot, he had to find a potter who wanted grain. Describe two problems with this system. How did the invention of coins make trade easier?
例题：在古埃及，人们常常直接交换物品。如果一个农民想要一个陶罐，他必须找到一个想要粮食的陶工。请描述该系统的两个问题。硬币的发明如何使贸易更便利？
Answer: The two problems are the double coincidence of wants – both people must want what the other offers – and the lack of a common measure of value. A farmer might not know how many sacks of grain equal one pot. Coins provided a medium of exchange and a unit of account, making trade simpler and fairer.
回答：两个问题是双重需求巧合——双方必须恰好想要对方提供的东西——以及缺乏共同的价值尺度。农民可能不知道多少袋粮食等于一个陶罐。硬币提供了交换媒介和记账单位，使贸易更简单和公平。
4. Science: Production Technology and Productivity | 科学：生产技术与社会生产力
Economics ties into science when we look at how technology improves productivity. A question might present data on hand-made versus machine-made items.
当我们研究技术如何提高生产力时，经济学与科学发生了关联。题目可能会给出手工制作与机器制造物品的数据。
Example: A factory produces pencils. Using manual labour, 10 workers produce 1 000 pencils per hour. After investing in a new machine, the same 10 workers can produce 4 500 pencils per hour. Calculate the increase in productivity per worker per hour. Explain how this affects the cost per pencil and the price the factory can charge.
例题：一家工厂生产铅笔。使用手工劳动，10名工人每小时生产1 000支铅笔。投资新机器后，同样10名工人每小时可生产4 500支铅笔。计算每个工人每小时的生产力提高量。解释这如何影响每支铅笔的成本以及工厂能收取的价格。
Solution: Productivity before: 1 000 ÷ 10 = 100 pencils per worker per hour. After: 4 500 ÷ 10 = 450 pencils per worker per hour. Increase = 350 pencils per worker per hour. Higher productivity means the cost per pencil falls because the same number of workers produce more. The factory can lower prices to attract more customers or keep prices the same and make more profit.
解答：之前生产力：1 000 ÷ 10 = 每名工人每小时100支。之后：4 500 ÷ 10 = 每名工人每小时450支。增加量 = 每名工人每小时350支。更高的生产力意味着每支铅笔的成本下降，因为同样数量的工人生产了更多。工厂可以降低价格以吸引更多顾客，或保持价格不变而获得更多利润。
5. Environmental Studies: Positive and Negative Externalities | 环境研究：正外部性与负外部性
A cross-curricular approach often brings in environmental issues. A question may ask about the impact of a new factory on a local river, linking economics and environmental science.
跨学科方法常引入环境问题。题目可能问及新建工厂对当地河流的影响，将经济学与环境科学联系起来。
Example: A new chocolate factory opens near a village. It employs 50 villagers, but its waste water flows into the river, killing fish. Identify one positive externality and one negative externality. Suggest one way the government could reduce the negative externality.
例题：一座新巧克力工厂在村庄附近开业。它雇用了50名村民，但其废水流进河里，杀死了鱼类。指出一个正外部性和一个负外部性。提出政府减少负外部性的一种方法。
Answer: Positive externality: job creation in the village. Negative externality: water pollution harming fish populations. The government could impose a tax on the factory for polluting or introduce regulations requiring waste treatment before discharge.
回答：正外部性：村庄里创造了就业机会。负外部性：水污染损害了鱼类种群。政府可以对污染工厂征税，或出台法规要求排放前进行废物处理。
6. Citizenship: Public Goods and Services | 公民教育：公共物品与服务
Economics interacts with citizenship by discussing who provides roads, streetlights, and national defence. A question might ask you to classify goods as public or private based on their characteristics.
经济学与公民教育互动，讨论谁提供道路、路灯和国防。题目可能让你根据特征将物品分类为公共物品或私人物品。
Example: List the following as public good, private good, or merit good: lighthouse, chocolate bar, school education, national defence,
