在 AQA IGCSE 地理考试中，高分离不开精选且细节准确的案例分析。这篇文章将带你进行一次实战演练：从选择、整理案例材料，到在限时条件下写出高分答案。你将接触到真实世界的范例，学会用阅卷官青睐的技巧组织答案，并看到一道典型 9 分题的完整示范解答。
1. Introduction to Case Study Questions in AQA IGCSE Geography | 介绍 AQA IGCSE 地理案例分析题
Case study questions appear across all three papers of the AQA IGCSE Geography specification (9230). They typically carry 6 to 9 marks and require you to ‘use an example’ or ‘name a place you have studied’. The examiner expects specific place detail, accurate data, and clear links between causes, effects and responses.
案例分析题出现在 AQA IGCSE 地理（9230）的所有三份试卷中。它们通常为 6 至 9 分，要求你“使用一个案例”或“说出你学过的一个地点”。阅卷官期望你给出具体的地点细节、准确的数据，以及原因、影响和应对措施之间的清晰联系。
You cannot earn top marks with generic statements. For instance, saying ‘many buildings collapsed’ is far weaker than ‘over 120,000 buildings were completely destroyed in the 2011 Tōhoku earthquake’. The key difference is named factual evidence tied to a specific event and location.
笼统的表述无法获得高分。例如，“许多建筑倒塌”远不如“2011 年东日本大地震中有超过 12 万栋建筑完全被毁”有力。关键区别在于，你的回答需要包含与具体事件和地点绑定的、有名有姓的事实证据。
2. How to Choose and Prepare Your Case Studies | 如何选择与准备案例分析材料
Start by building a case study bank that covers the main themes: tectonic hazards, weather hazards, climate change, coasts, rivers, ecosystems, urban environments, economic development and resource management. For each theme, select one detailed case study in an LEDC/NEE and one in an MEDC/HIC to enable comparison.
首先建立一个覆盖主要主题的案例库：构造灾害、天气灾害、气候变化、海岸、河流、生态系统、城市环境、经济发展和资源管理。每个主题选择一个位于欠发达国家/新兴经济体的详细案例和一个位于较发达国家/高收入国家的案例，以便进行对比。
Create concise revision cards for each case. Structure them under clear headings: Location & background, Causes, Primary effects, Secondary effects, Immediate responses, Long-term responses, and Evaluation of management. Use bullet points, abbreviations and precise statistics – the date, magnitude, death toll, cost of damage and length of recovery are all essential.
为每个案例制作简明的复习卡片。结构使用清晰的标题：地点与背景、起因、直接影响、间接影响、即时反应、长期应对措施和管理评价。使用要点、缩略语和精确的统计数据——日期、震级、死亡人数、经济损失和恢复时长都是必不可少的。
3. Key Themes and Case Study Categories | 关键主题与案例分类
The AQA specification expects you to study case studies across both physical and human geography. Below is a summary of typical case study categories and some commonly used examples. You should adapt the table to include the exact examples your teacher has covered.
AQA 考纲要求你学习自然地理和人文地理两方面的案例。下表总结了典型的案例类别和一些常用范例。你应根据老师讲授的内容调整表格，加入你实际学过的案例。
| Theme | 主题 | Sample LEDC/NEE case | 欠发达国家/新兴经济体范例 | Sample MEDC/HIC case | 较发达国家/高收入国家范例 |
|---|---|---|
| Tectonic hazards | 构造灾害 | Nepal earthquake 2015 | Tōhoku earthquake & tsunami 2011 |
| Tropical storms | 热带风暴 | Typhoon Haiyan, Philippines 2013 | Hurricane Katrina, USA 2005 |
| Coastal erosion | 海岸侵蚀 | Sundarbans, Bangladesh | Holderness Coast, UK |
| Urban challenges | 城市挑战 | Rio de Janeiro, Brazil | London, UK |
| Economic development | 经济发展 | China’s economic growth | Japan’s post-1945 recovery |
4. Case Study Focus: Tectonic Hazards – The 2011 Tōhoku Earthquake and Tsunami | 案例聚焦：构造灾害—2011 年东日本大地震与海啸
On 11 March 2011, a magnitude 9.0 megathrust earthquake struck 70 km off the coast of Honshu, Japan. The quake generated a devastating tsunami with wave heights reaching over 40 metres in Miyako.
2011 年 3 月 11 日，一场 9.0 级的逆冲型大地震袭击了日本本州岛海岸 70 公里处。地震引发了毁灭性海啸，在宫古市的波高达到 40 米以上。
Primary effects included the shifting of Honshu 2.4 metres eastwards and over 15,800 deaths. The tsunami caused the meltdown at the Fukushima Daiichi nuclear power plant, leading to a nuclear emergency and the long-term evacuation of over 100,000 people.
直接影响包括本州岛向东移动 2.4 米，超过 15,800 人死亡。海啸导致福岛第一核电站发生堆芯熔毁，引发核紧急状况，并迫使超过 10 万人长期撤离。
Immediate responses involved 100,000 soldiers mobilised for search and rescue, and the government issuing tsunami warnings within three minutes. Long-term responses included the construction of higher sea walls (some up to 14.7 m), the establishment of the Reconstruction Agency, and an investment of ¥32 trillion in rebuilding.
即时反应包括动员 10 万名自卫队员进行搜救，政府在 3 分钟内发布海啸警报。长期应对措施包括修建更高的防波堤（部分高达 14.7 米）、成立复兴厅，以及投入 32 万亿日元用于重建。
Evaluation: Japan’s preparedness – strict building codes and early warning systems – saved thousands of lives, yet the nuclear disaster exposed unexpected vulnerabilities. You can use this case to discuss both the success of prediction and the limits of protection.
评价：日本的备灾措施——严格的建筑规范和预警系统——挽救了成千上万的生命，但核灾难暴露了意想不到的脆弱性。你可以用这个案例来探讨预报的成功与防护的局限。
5. Case Study Focus: Tropical Storms – Typhoon Haiyan, Philippines 2013 | 案例聚焦：热带风暴—2013 年菲律宾台风海燕
Typhoon Haiyan (local name Yolanda) made landfall on 8 November 2013. It was one of the strongest tropical storms ever recorded, with sustained winds of 315 km/h and a storm surge of over 5 metres.
台风海燕（当地名称“尤兰达”）于 2013 年 11 月 8 日登陆。它是有记录以来最强的热带风暴之一，持续风速达 315 公里/小时，风暴潮超过 5 米。
The primary effects were catastrophic: over 6,300 deaths, 90% of Tacloban City destroyed, and roughly 4 million people displaced. The storm surge was the main killer, sweeping away entire settlements along the coast.
直接影响是灾难性的：超过 6,300 人死亡，独鲁万市 90% 被毁，约 400 万人流离失所。风暴潮是主要杀手，将沿海整个定居点一扫而空。
Immediate responses were hindered by blocked roads and a destroyed airport. International aid arrived within days, but distribution was slow. The UN launched a $791 million appeal. In the long term, the government implemented a ‘Build Back Better’ programme, relocating vulnerable communities and constructing storm surge barriers.
即时反应因道路堵塞和机场被毁而受阻。国际援助在数日内抵达，但物资分发缓慢。联合国发起了 7.91 亿美元的募捐呼吁。长期来看，政府实施了“重建得更好”计划，迁走了易受灾的社区，并修建了风暴潮屏障。
This case is ideal for evaluating the effectiveness of aid in a developing country. You can contrast the slow initial response with the increased resilience achieved through the long-term relocation scheme.
该案例非常适合评价发展中国家援助的有效性。你可以将缓慢的初期响应与通过长期搬迁计划所提升的韧性进行对比。
6. Case Study Focus: Coastal Erosion and Management – Holderness Coast, UK | 案例聚焦：海岸侵蚀与管理—英国霍尔德内斯海岸
The Holderness Coast in East Yorkshire is Europe’s fastest-eroding coastline, with an average retreat of 2 metres per year. The cliffs are made of soft boulder clay, easily eroded by wave action, and the prevailing north-easterly winds drive destructive waves onto the shore.
东约克郡的霍尔德内斯海岸是欧洲侵蚀速度最快的海岸线，平均每年后退 2 米。悬崖由松软的冰砾泥构成，极易被波浪侵蚀，而盛行的东北风将破坏性波浪推向岸边。
Key locations show contrasting management approaches. At Mappleton, a rock armour revetment and two rock groynes were built in 1991, costing £2 million. The scheme successfully halted erosion of the village but starved beaches farther south of sediment, accelerating erosion at Great Cowden.
关键地点展示了不同的管理方式。在梅普尔顿，1991 年修建了抛石护岸和两座块石丁坝，耗资 200 万英镑。方案成功阻止了村庄的侵蚀，却导致泥沙无法补给南部的海滩，加速了大考登的侵蚀。
In contrast, the area of Spurn Head is left without active protection, managed under a policy of ‘no active intervention’. This allows natural processes to shape the spit, but also means the lifeboat station and access road are frequently threatened.
相比之下，斯珀恩角地区没有主动防护，采用“不主动干预”政策。这让自然过程继续塑造沙嘴，但也意味着救生艇站和通道经常受到威胁。
Use this case to weigh the costs and benefits of hard engineering and the knock-on effects down the coast. You can also link it to the concept of Integrated Coastal Zone Management (ICZM).
运用这个案例来权衡硬工程的成本收益与其对沿岸的连锁影响。你还可以将其与海岸带综合管理（ICZM）的概念联系起来。
7. Case Study Focus: Urban Challenges – Rio de Janeiro, Brazil | 案例聚焦：城市挑战—巴西里约热内卢
Rio de Janeiro has experienced rapid urbanisation, with its population growing to over 6.7 million in the metropolitan area. This has led to widespread informal settlements known as favelas, where roughly 1.5 million people live in overcrowded conditions with limited access to clean water and sanitation.
里约热内卢经历了快速城市化，大都市区人口增长至超过 670 万。这导致了大规模的非正式定居点——贫民窟的出现，约 150 万人生活在那里，居住条件拥挤，缺乏清洁用水和卫生设施。
The city faces multiple challenges: traffic congestion, air pollution, crime, and a shortage of affordable housing. In Rocinha, the largest favela, many houses are self-built on steep slopes, making them vulnerable to landslides during heavy rain.
该城市面临多重挑战：交通拥堵、空气污染、犯罪，以及经济适用房短缺。在最大的贫民窟罗西尼亚，许多房屋是自行建造在陡坡上，暴雨时易受滑坡威胁。
Responses include the Favela Bairro project, which upgraded selected favelas by paving roads, installing drainage, and providing cable car connections. The programme improved the quality of life for many but was criticised for not tackling underlying issues of land tenure and income inequality.
应对措施包括“贫民区改造”项目，通过铺设道路、安装排水系统和提供缆车连接来升级部分贫民窟。该计划改善了许多人的生活质量，但被批评未能解决土地所有权和收入不平等的根本问题。
An excellent case for examining the sustainability of urban improvement strategies. You should contrast top-down approaches with community-led projects such as the Morar Carioca plan.
这是考察城市改善策略可持续性的绝佳案例。你应将自上而下的方法与社区主导的项目（如 Morar Carioca 计划）进行对比。
8. Case Study Focus: Development and the Global Shift – China’s Economic Growth | 案例聚焦：发展与全球转移—中国经济增长
Since the opening-up reforms in 1978, China has transformed from a largely agricultural economy into the world’s second largest. Key factors include the establishment of Special Economic Zones (SEZs) like Shenzhen, massive investment in manufacturing, and the shift of global production to China due to low labour costs.
自 1978 年改革开放以来，中国从以农业为主的经济体转变为世界第二大经济体。关键因素包括设立深圳等经济特区、大规模投资制造业，以及因劳动力成本低廉全球生产向中国转移。
The positive impacts are stark: GDP per capita rose from $156 in 1978 to over $12,000 today, and the poverty rate fell from 88% to below 1%. Infrastructure has expanded rapidly, with the world’s largest high-speed rail network now operating.
积极影响十分显著：人均 GDP 从 1978 年的 156 美元升至今天的超过 12,000 美元，贫困率从 88% 降至 1% 以下。基础设施迅速扩张，现已建成全球最大的高速铁路网络。
However, rapid industrialisation has caused severe environmental problems. Air pollution in cities like Beijing frequently exceeds WHO safe limits, and over-extraction of groundwater has led to subsidence. The government is now promoting a shift towards a green economy, investing heavily in solar and wind energy.
然而，快速工业化也造成了严重的环境问题。北京等城市的空气污染经常超过世卫组织的安全限值，地下水的过量开采也导致地面沉降。政府现正推动绿色经济转型，大力投资太阳能和风能。
In an exam, link this case to the Clark-Fisher model and the multiplier effect. You can discuss how the global shift has created both opportunities and challenges for China’s society and environment.
在考试中，将这个案例与克拉克-费舍尔模型和乘数效应联系起来。你可以探讨全球转移如何为中国的社会和环境带来机遇和挑战。
9. Structuring Your Answer: Using the PEEL Technique | 组织你的答案：运用 PEEL 技巧
For high-mark case study questions, unstructured narratives will lose marks. Use PEEL: Point, Evidence, Explanation, Link. For example, ‘An immediate response to the Tōhoku earthquake was the rapid mobilisation of emergency teams (Point). Over 100,000 soldiers were deployed within 24 hours (Evidence). This reduced the number of secondary deaths from exposure and untreated injuries (Explanation). This shows that a well-drilled emergency plan can significantly improve outcomes, even in a high-magnitude event (Link).’
高分案例分析题中，结构混乱的叙述会失分。请使用 PEEL：观点、证据、解释、联系。例如：“东日本大地震的一个即时反应是快速动员应急队伍（观点）。24 小时内部署了超过 10 万名军人（证据）。这减少了因暴露和未及时救治造成的二次死亡（解释）。这表明，即使在高震级事件中，训练有素的应急预案也能显著改善结果（联系）。”
Every paragraph should connect back to the question. If the question asks you to evaluate, use evaluative language such as ‘this was more effective than… because…’ or ‘however, the long-term impact was limited by…’.
每个段落都应回扣题目。若题目要求评价，使用评价性语言，如“这比……更有效，因为……”或“然而，长期影响受到……的限制”。
10. Exam-style Practice Question with Model Answer | 考试风格练习题与示范答案
Question: ‘For a named example of a tropical storm you have studied, assess the effectiveness of the immediate and long-term responses.’ (9 marks)
题目：“就你学过的一个热带风暴案例，评价即时反应和长期应对措施的有效性。”（9 分）
Model answer – Point 1: I have studied Typhoon Haiyan, which struck the Philippines in 2013. The immediate response was coordinated by the government and international agencies, but its effectiveness was severely limited by damaged infrastructure.
示范答案——第 1 点：我学习了 2013 年袭击菲律宾的台风海燕。即时响应由政府和国际机构协调，但由于基础设施受损，其有效性受到严重限制。
Model answer – Point 2: For example, only 48 hours after landfall, the US military delivered food and water, yet the destroyed Tacloban Airport meant that supplies were bottlenecked, and many remote communities remained unreached for over a week. This shows that even well-funded efforts can fail if physical access is blocked.
示范答案——第 2 点：例如，登陆仅 48 小时后，美军就送达了食物和水，但被毁的独鲁万机场导致物资分发受阻，许多偏远社区超过一周无法得到援助。这表明，即使资金充足的援助，若物理通道被阻断也会失败。
Model answer – Point 3: In contrast, the long-term response was more effective. The ‘Build Back Better’ programme relocated 205,000 households away from high-risk coastal zones and constructed 50 km of storm surge barriers. This addressed the root cause of vulnerability, not just the symptoms.
示范答案——第 3 点：相比之下，长期应对更为有效。“重建得更好”计划将 205,000 户家庭迁离高风险沿海地带，并修建了 50 公里的风暴潮屏障。这解决了脆弱性的根源，而非仅仅处理表面问题。
Model answer – conclusion: Overall, while the immediate response saved lives, its effectiveness was hampered by geographical barriers. The long-term response, focusing on relocation and resilient infrastructure, provided a more sustainable reduction in risk, making it the more effective phase. (9/9)
示范答案——总结：总体而言，即时响应拯救了生命，但其有效性受地理障碍制约。长期应对侧重于搬迁和弹性基础设施，更可持续地降低了风险，因而是更有效的阶段。（9 分满分）
11. Common Mistakes and How to Avoid Them | 常见错误与如何避免
One frequent error is writing generic paragraphs without naming a specific place or event. Avoid starting with ‘In some countries, earthquakes cause…’ Always explicitly state the name and date of your case study in the first sentence.
一个常见错误是写了泛泛的段落而没有说出具体的地点或事件。要避免以“在一些国家，地震造成……”开头。始终在第一句明确陈述你所使用案例的名称和日期。
Another mistake is listing effects without explanation. Do not just say ‘6000 people died’. Add the link: ‘…which led to a shortage of labour and a long-term economic downturn in the region.’ Also, avoid data dumping – every figure must be interpreted or linked to the question.
另一个错误是只罗列影响而不解释。不要只写“6000 人死亡”。要加上联系：“……这导致劳动力短缺和该地区长期经济衰退。”此外，避免数据堆砌——每个数字都必须被解读或与问题挂钩。
Finally, many students forget to evaluate. Even if the question uses the command word ‘describe’, higher marks require some assessment. When you see ‘assess’ or ‘evaluate’, you must weigh strengths against limitations and provide a justified conclusion.
最后，许多学生忘记评价。即使题目使用了“描述”这个词，高分也需要一些评判。当你看到“评价”或“评估”时，你必须权衡优点和局限，并给出有理有据的结论。
12. Final Tips for Exam Success | 考前成功贴士
Revise actively by rehearsing your case study facts aloud or by writing them out from memory under timed conditions. Your aim is to recall the five key statistics for each case within 30 seconds. Practice planning a 9-mark answer in 2 minutes before you start writing, so your ideas flow logically.
主动复习，大声复述案例事实，或在限时条件下默写。你的目标是在 30 秒内回忆起每个案例的五个关键统计数据。练习在动笔前用两分钟规划一道 9 分题的答案，这样你的思路能有逻辑地展开。
On exam day, you will face a choice of case study questions. Pick the one for which you can provide the most precise place detail and a clear evaluation. Trust your preparation, and always leave 2 minutes at the end to check you have linked every point back to the question.
考试当天，你会面临案例分析题的选择。选择你能提供最精确地点细节和清晰评价的那一道。相信你的准备，并始终在最后留出两分钟检查是否每个要点都回扣了问题。
