Case studies are the beating heart of Cambridge IGCSE Geography. They transform abstract theory into vivid, real-world understanding and are essential for scoring top marks, especially in the 7‑mark and essay‑style questions.
案例分析是剑桥IGCSE地理的核心。它们将抽象理论转化为生动的现实理解，对于在7分题和论文式问题中获得高分不可或缺。
This guide is your ultimate hands‑on drill session. It will teach you how to select, structure and apply case studies with precision, using authentic examples from the syllabus. By working through the practice sections, you will build the confidence to handle any case‑study question in Paper 1, Paper 2 and beyond.
本指南是你终极的实战演练。它将教你如何精准地选择、构建和运用案例，并使用大纲中的真实例子。通过完成练习部分，你将建立起应对试卷一、试卷二中任何案例研究问题的信心。
1. Understanding Case Studies in Cambridge Geography | 理解剑桥地理案例分析
A case study is a detailed, real‑world example that illustrates a geographical process, issue or management strategy. You must know specific facts, locations, names and statistics, rather than just describing a general concept.
案例分析是一个详实的真实世界例子，用以说明地理过程、问题或管理策略。你必须掌握具体的事实、地点、名称和统计数据，而不仅仅是描述一个笼统的概念。
The examiner expects you to integrate case‑study knowledge seamlessly into your answer. It is not enough to bolt on a few sentences at the end; your example should support every analytical point you make.
考官期望你将案例分析知识无缝地融入到答案中。仅仅在末尾附加几句话是不够的；你的例子应支持你所提出的每一个分析点。
Cambridge IGCSE Geography requires you to study a range of case studies across the four themes: Population and Settlement, The Natural Environment, Economic Development, and Geographical Skills. You must be able to recall details under timed conditions.
剑桥IGCSE地理要求你学习四大主题中的一系列案例：人口与定居、自然环境、经济发展和地理技能。你必须在限时条件下能够回忆起细节。
2. Overview of Case Study Types | 案例类型速览
Different topics demand different kinds of examples. Familiarise yourself with the most common case‑study categories so you can match the right example to the question.
不同的主题需要不同类型的例子。熟悉最常见的案例类别，以便你能将正确的例子与问题匹配起来。
| Theme / 主题 | Example Case Study / 案例 |
|---|---|
| Urban environments | Rio de Janeiro, Brazil | 巴西里约热内卢 |
| Settlement and service provision | Mumbai, India | 印度孟买 |
| Coastal processes and management | Holderness Coast, UK | 英国霍尔德内斯海岸 |
| River environments | River Ganges, India | 印度恒河 |
| Tectonic hazards | Nepal Earthquake 2015 | 2015年尼泊尔地震 |
| Tropical storms | Typhoon Haiyan, Philippines 2013 | 2013年菲律宾台风海燕 |
| Economic development | Nigeria | 尼日利亚 |
| Transnational corporations | Shell in Nigeria | 壳牌在尼日利亚 |
| Water resources | Lesotho Highland Water Project | 莱索托高地水利工程 |
The above table is a starting point. Always check your syllabus, as some versions prescribe specific case studies that must be studied in depth.
以上表格只是一个起点。务必核对你的教学大纲，因为某些版本规定了必须深入学习的特定案例。
3. Frameworks for High‑Scoring Answers | 构建高分答案的框架
Use a clear structure to organise case‑study details. The standard P.E.E.L. (Point, Evidence, Explanation, Link) or a slightly adapted version works well.
使用清晰的结构来组织案例细节。标准的P.E.E.L.（观点、证据、解释、联系）或稍加改编的版本效果很好。
Point: State the geographic concept you are demonstrating. Evidence: Quote a specific fact or figure from your case study. Explanation: Analyse how the evidence supports the point. Link: Refer back to the question or to the next paragraph.
观点：陈述你正在论证的地理概念。证据：引用案例中的具体事实或数据。解释：分析证据如何支持观点。联系：回扣问题或承接到下一段落。
For longer 7‑mark questions, you might use a 'two‑sided' framework: present the social, economic and environmental impacts, or discuss advantages and disadvantages. Always let the command word guide your layout.
对于较长的7分题，你可以使用“双面”框架：呈现社会、经济和环境影响，或讨论优点与缺点。务必让指令词引导你的布局。
4. Decoding Command Words | 解读指令词
Command words such as 'describe', 'explain', 'assess' and 'evaluate' dictate the level of analysis required. Misreading them is one of the fastest ways to lose marks.
诸如“描述”、“解释”、“评估”和“评价”等指令词决定了所需的解析深度。误读指令词是失分的最快途径之一。
Describe: Say what something is like, using factual detail. Explain: Give reasons why something happens or has developed. Assess: Weigh up the importance of different factors and reach a supported judgement. Evaluate: Judge the success or effectiveness of a scheme, often by considering multiple criteria.
描述：用事实细节说明事物的状况。解释：给出某事发生或发展的原因。评估：权衡不同因素的重要性，并得出有据支撑的判断。评价：通常通过考虑多个标准来评判某项方案是否成功或有效。
In a case‑study question, if you are asked to 'assess the success of flood management', do more than list measures; you must evaluate how well they worked, citing evidence of reduced damage or community feedback.
在案例研究问题中，如果要求你“评估洪水管理的成功程度”，不要仅仅罗列措施；你必须评估它们的成效，引用减少损失的证据或社区反馈。
5. Using Facts and Figures Effectively | 有效使用事实与数据
Accurate data makes your case study convincing. Memorise 3–5 key statistics for each case study, such as population, area, annual precipitation, magnitude of hazard, or percentage of GDP.
准确的数据能让你的案例令人信服。为每个案例记住3–5个关键统计数据，如人口、面积、年降水量、灾害震级或国内生产总值百分比。
Place facts strategically: open a paragraph with a statistic to grab attention, then explain its significance. For example, 'With over 13 million inhabitants, Rio de Janeiro faces severe housing pressure.'
策略性地运用事实：用一个统计数据作为段落的开头以吸引注意力，然后解释其意义。例如，“拥有超过1300万居民，里约热内卢面临着严重的住房压力。”
Avoid vague language like 'a lot of people' or 'very high growth'. Replace these with precise numbers and use comparative words such as 'double' or 'a third higher than the national average'.
避免使用“很多人”或“非常高的增长”等模糊语言。用精确数字替代，并使用“翻倍”或“比全国平均水平高出三分之一”等比较性词语。
6. Practice: Urban Environments – Rio de Janeiro | 实战演练：城市环境 – 里约热内卢
Rio de Janeiro is a rapidly growing city in Brazil, offering a rich example of challenges facing megacities in Lower Income Countries (LICs) and Newly Emerging Economies (NEEs).
里约热内卢是巴西一个快速发展的城市，为低收入国家和新兴经济体中的超级城市面临的挑战提供了丰富的例子。
Key facts: Population approximately 13.5 million in the metropolitan area. Over one million people live in favelas, informal settlements often built on steep hillsides. The city hosted the 2014 World Cup and 2016 Olympics, triggering regeneration but also social tensions.
关键事实：大都会区人口约1350万。超过100万人居住在贫民窟，这些非正规定居点常建在陡峭的山坡上。该市举办了2014年世界杯和2016年奥运会，触发了城市更新但也引发了社会紧张。
Squatter settlement challenges: lack of sanitation, poor access to clean water, high crime rates, and vulnerability to landslides. Rocinha is the largest favela, with an estimated 100,000–200,000 residents.
棚户区挑战：缺乏卫生设施、清洁水资源获取困难、犯罪率高、易受山体滑坡影响。Rocinha是最大的贫民窟，居民约10万至20万人。
Self‑help housing schemes, such as the Favela‑Bairro Project, have brought paved roads, electricity, and title deeds to some favelas, but funding is limited. The authorities also attempted forced evictions before the Olympics, drawing sharp criticism from human rights groups.
自助住房计划（如Favela‑Bairro项目）为一些贫民窟带来了铺设道路、电力和产权证书，但资金有限。当局在奥运会前还进行了强制拆迁，引来了人权组织的尖锐批评。
When using Rio in an exam, connect your facts directly to the question. If asked about 'urban challenges', always balance social, economic and environmental aspects.
在考试中使用里约的例子时，将事实直接与问题联系起来。如果被问及“城市挑战”，始终要平衡社会、经济和环境方面。
7. Practice: Coastal Processes – Holderness Coast | 实战演练：海岸过程 – 霍尔德内斯海岸
The Holderness Coast in eastern England is the fastest‑eroding coastline in Europe. It provides a classic case study of cliff recession and coastal management conflict.
英格兰东部的霍尔德内斯海岸是欧洲侵蚀最快的海岸线。它提供了悬崖后退和海岸管理冲突的经典案例。
Key facts: The coast loses an average of 2 metres per year, with some areas losing up to 10 metres in a single storm event. The cliffs are composed mainly of soft boulder clay, easily eroded by wave action and weather.
关键事实：该海岸线平均每年后退2米，某些区域在一次暴风雨中可后退多达10米。悬崖主要由松软的冰砾泥组成，易受波浪作用和风雨侵蚀。
Coastal management includes hard engineering such as rock groynes and sea walls at Mappleton, and soft engineering such as beach nourishment at Hornsea. Managed retreat allows the sea to flood low‑value land, creating salt marsh habitat.
海岸管理包括硬工程，如Mappleton的防波堤和海堤，以及软工程，如Hornsea的海滩养护。管理性撤退允许海水淹没低价值土地，从而创造盐沼栖息地。
Conflict arises because protecting one section often starves down‑drift beaches of sediment, accelerating erosion further south. Farmers and residents demand protection, but government policy favours cost‑benefit analysis, leading to heated debates.
冲突之所以产生，是因为保护某一段海岸往往会使下游海滩缺乏沉积物补给，加剧更南侧的侵蚀。农民和居民要求保护，但政府政策倾向于成本效益分析，由此引发激烈辩论。
For high marks, compare the economic cost of protection with the value of property and infrastructure saved, and mention the Sellafield gas terminal, which receives powerful defences because of its national importance.
为了高分，要将保护的经济成本与被挽救的财产和基础设施价值进行对比，并提及Sellafield天然气终端，由于其国家重要性而拥有强大的防护设施。
8. Practice: Tectonic Hazards – Nepal Earthquake 2015 | 实战演练：构造灾害 – 2015年尼泊尔地震
The 7.8‑magnitude earthquake that struck on 25 April 2015 devastated parts of Nepal, making it a vital case study for understanding tectonic hazard impacts in LICs.
2015年4月25日发生的7.8级地震摧毁了尼泊尔部分地区，使其成为理解低收入国家构造灾害影响的重要案例。
Key facts: Epicentre near Lamjung district, shallow depth of 15 km. Over 8,800 people killed, 22,300 injured, and more than 600,000 buildings collapsed. The earthquake triggered avalanches on Mount Everest and landslides across steep valleys.
关键事实：震中在Lamjung地区附近，震源深度仅15公里。逾8,800人遇难，22,300人受伤，超过60万座建筑倒塌。地震引发了珠穆朗玛峰的雪崩和陡峭山谷的山体滑坡。
Primary effects included widespread destruction of historic monuments such as Dharahara Tower, and massive damage to roads and telecommunications. Secondary effects involved food shortages, waterborne diseases, and a significant drop in tourism revenue.
主要影响包括达拉哈拉塔等历史古迹的广泛破坏，以及道路和通信设施的大规模受损。次要影响包括粮食短缺、水传播疾病爆发以及旅游收入大幅下降。
Short‑term responses were hindered by landslides that blocked access to remote villages, and the international aid effort was complicated by coordination problems. Long‑term recovery focused on 'building back better' with earthquake‑resistant construction, though progress remains slow due to poverty and corruption.
短期应对因山体滑坡阻断通往偏远村庄的道路而受阻，国际援助工作也因协调问题而复杂化。长期恢复聚焦于“重建得更好”，采用抗震建筑，但由于贫困和腐败，进展依然缓慢。
Always describe the tectonic setting: the earthquake resulted from the collision of the Indian Plate with the Eurasian Plate, a destructive plate boundary. Mentioning plate tectonics roots your answer firmly in physical geography.
务必描述构造背景：地震源于印度板块与欧亚板块的碰撞，属于破坏性板块边界。提及板块构造能使你的答案牢牢扎根于自然地理之中。
9. Practice: Economic Development – Nigeria | 实战演练：经济发展 – 尼日利亚
Nigeria is a leading NEE in West Africa, making it an excellent case study for balanced economic development and the role of transnational corporations.
尼日利亚是西非领先的新兴经济体，使其成为研究均衡经济发展及跨国公司角色的绝佳案例。
Key facts: Africa's largest economy by GDP (approx. $480 billion). Population over 220 million. Oil and natural gas account for over 90% of export earnings, but the country is diversifying into telecommunications, agriculture and entertainment (Nollywood).
关键事实：按国内生产总值计算，是非洲最大经济体（约4800亿美元）。人口超过2.2亿。石油和天然气占出口收入的90%以上，但国家正在向电信、农业和娱乐（Nollywood）多元化发展。
Aid versus trade: Nigeria receives significant foreign aid, but some argue that trade is more sustainable. The Ajaokuta Steel Mill, funded by foreign loans, was meant to kick‑start industrialisation but remains largely non‑operational, illustrating the pitfalls of top‑down development.
援助与贸易：尼日利亚接收大量外援，但有些人认为贸易更具可持续性。由外国贷款资助的Ajaokuta钢铁厂本应启动工业化，但基本仍未运营，说明了自上而下发展的隐患。
Shell’s operations in the Niger Delta have brought jobs and infrastructure but also oil spills, gas flaring, and conflict with local communities. The Ogoni people’s activism highlights tensions between economic growth and environmental justice.
壳牌在尼日尔三角洲的运营带来了就业和基础设施，但也带来了漏油、天然气燃除和与当地社区的冲突。奥格尼人的运动凸显了经济增长与环境正义之间的张力。
Quality of life indicators vary widely: GDP per capita has risen, yet over 40% of the population lives below the poverty line. Regional disparities between the oil‑rich south and the agrarian north remain stark.
生活质量指标差异巨大：人均GDP虽已上升，但仍有超过40%的人口生活在贫困线以下。石油丰富的南部与以农业为主的北部之间的区域差距依然明显。
10. Common Mistakes and How to Avoid Them | 常见错误与避免方法
One frequent mistake is mixing up locations: placing Rio in Africa or claiming the Nepal earthquake happened on a divergent boundary. Drill yourself on a blank map until the locations are second nature.
一个常见错误是把地点搞混：把里约热内卢放到非洲，或声称尼泊尔地震发生在离散边界上。拿一张空白地图反复练习，直到地点成为第二本能。
Another pitfall is listing facts without analysis. Always link your statistic to an impact or a reason. Instead of writing 'Over 600,000 buildings collapsed in Nepal,' add 'which left hundreds of thousands homeless and increased the risk of waterborne diseases.'
另一个陷阱是罗列事实而不分析。始终将你的统计数据与影响或原因联系起来。与其写下“尼泊尔超过60万座建筑倒塌”，不如补充“导致数十万人无家可归，并增加了水传播疾病的风险。”
Using unverified or outdated data can damage your credibility. Stick to those given in your textbook or official exam board resources. Avoid mentioning population figures unless you are certain.
使用未经验证或过时的数据会损害你的可信度。坚持使用教科书或官方考局资源中提供的数据。除非你有把握，否则不要提及人口数字。
Failing to address the command word is the most costly error. If asked to 'evaluate', you must give a balanced conclusion with a clear judgement. Practise writing a final evaluative sentence for each of your case studies.
没有回应指令词是代价最高的错误。如果要求“评价”，你必须给出一个平衡的结论，并表达明确的判断。为你的每个案例练习写一个总结性的评价句子。
11. Top Tips for Exam Success | 考试高分秘诀
Create a one‑page summary card for each case study. Include a tiny location map, the three most critical statistics, and bullet points for social, economic and environmental aspects. Review these cards daily in the final weeks.
为每一个案例制作一张一页纸的摘要卡。包含一个小位置地图、三个最关键的数据，以及社会、经济和环境方面的要点。在最后几周里每天复习这些卡片。
In the exam, underline the command word and the specific theme asked. Then spend 30 seconds jotting down the case study you intend to use, along with three supporting facts. This prevents you drifting off topic.
考试时，在指令词和所问的具体主题下划线。然后花30秒记下你打算使用的案例，以及三个支撑事实。这能防止你偏离题目。
Time management is crucial. For a 7‑mark question, allocate about 10 minutes. Use the first 2 minutes for planning, 6 minutes for writing, and 2 minutes for checking your spelling of place names and the inclusion of accurate data.
时间管理至关重要。对于7分题，分配大约10分钟。前2分钟规划，6分钟书写，2分钟检查地名拼写和是否包含了准确数据。
Link your case study back to the wider geographical concept. For instance, after discussing the Holderness Coast, connect it to the concept of coastal systems being dynamic and interdependent.
将你的案例与更广泛的地理概念联系起来。例如，在讨论了霍尔德内斯海岸后，联系到海岸系统是动态且相互依存的概念。
12. Your Turn: Self‑Assessment Drill | 你的回合：自我评估训练
Use the following questions to test your case‑study readiness. Write full answers under timed conditions, then evaluate them using the mark scheme or ask a peer to review.
