Case studies form the backbone of CIE IGCSE Geography examinations. They demonstrate your ability to apply geographical theory to real‑world situations, moving beyond simple definitions. This article provides a structured practical workout to help Year 11 students master case‑study answers, from selecting the right information to structuring high‑scoring responses. Each section includes a hands‑on exercise with a modelled answer, allowing you to train your skills for the final exam.
案例研究是 CIE IGCSE 地理考试的基石。它们展示了你将地理理论应用于现实情境的能力，超越了简单的定义。本文提供一个结构化的实战训练，帮助 Year 11 学生掌握案例研究答案，从选择正确的信息到构建高分回答。每个部分都包含一个实践练习与示范答案，让你为最终考试磨练技能。
1. Understanding the Role of Case Studies in CIE IGCSE Geography | 理解案例研究在考试中的作用
In CIE IGCSE Geography, Paper 1 and Paper 2 require you to refer to specific, named examples when answering extended‑response questions. A case study is not merely a place name; it is a detailed illustration of a geographical process, complete with statistics, impacts, and management strategies. Examiners look for depth and precision, rewarding answers that integrate location‑specific facts rather than generic statements.
在 CIE IGCSE 地理中，试卷一和试卷二要求你在回答论述题时引用具体的、命名的例子。案例研究不仅仅是一个地名；它是一个详细的地理过程例证，包含统计数据、影响和管理策略。考官寻找深度和精确性，奖励那些整合特定地点事实而不是泛泛而谈的答案。
Questions are often worth 5 to 7 marks, and the command words ‘explain’, ‘describe the impacts’ or ‘evaluate the management’ demand a structured narrative. Your case‑study knowledge must include three core components: causes (why something happened), consequences (environmental, social, economic) and responses (how people managed or mismanaged the situation). Without a rich bank of case studies, you cannot access the higher mark bands.
题目通常分值 5 至 7 分，指令词“解释”“描述影响”或“评价管理”需要一个结构化的叙述。你的案例研究知识必须包含三个核心组成部分：原因（为什么会发生）、后果（环境、社会、经济）和响应（人们如何管理或管理不善）。如果没有丰富的案例研究库，你就无法进入更高的分数段。
2. Selecting and Summarising Your Case Studies | 选择和总结你的案例研究
It is impossible to memorise every detail about dozens of places. Instead, choose one or two clear, contrasting case studies per theme. For example, for population you might use Nigeria (a youthful population) and Japan (an ageing population). Make a concise summary card for each case, following the ‘Causes – Consequences – Responses’ framework, and include at least three specific place facts (e.g. dates, percentages, named landmarks).
你不可能记住几十个地方的所有细节。相反，为每个主题选择一个或两个清晰、对比鲜明的案例研究。例如，对于人口，你可以使用尼日利亚（年轻人口结构）和日本（老龄化人口结构）。为每个案例制作一个简洁的总结卡片，遵循“原因 – 后果 – 响应”框架，并包含至少三个具体的地点事实（如日期、百分比、命名的地标）。
Keep your summaries flexible. Do not write a rigid essay; instead, list bullet points under each heading. Because exam questions can ask for only one aspect, you must be able to retrieve relevant facts quickly. During your workout, practice under timed conditions: read a question, jot down the key facts from memory, then check against your notes. This active recall builds the neural connections essential for the exam hall.
让你的总结保持灵活。不要写一篇僵化的文章；相反，在每个标题下列出要点。因为考试题目可能只要求某一个方面，你必须能够快速提取相关事实。在训练中，在限时条件下练习：阅读一个问题，凭记忆记下关键事实，然后与你的笔记核对。这种主动回忆能建立考场必备的神经连接。
3. The PEEL Framework for Case Study Answers | PEEL框架作答案例研究题
The PEEL model (Point, Evidence, Explanation, Link) is an effective structure for extended case‑study responses. Start with a clear Point that directly addresses the question. Then provide your Evidence – named place and specific data. Next, Explain how the evidence supports the point, showing causal connections. Finally, Link back to the overall question or the next paragraph. This method prevents vague answers and keeps you focused on the command word.
PEEL 模型（观点、证据、解释、联系）是案例研究论述题的有效结构。从一个直接回应问题的清晰观点开始。然后提供你的证据——命名的地点和具体数据。接下来，解释证据如何支持观点，展示因果联系。最后，联系回整个问题或下一段落。这种方法能避免含糊答案，并使你专注于指令词。
For example, if asked about the impacts of river flooding, a PEEL paragraph might be: Point – ‘Flooding caused severe social disruption in the town of York.’ Evidence – ‘In December 2015, the River Ouse burst its banks, inundating 600 homes and forcing 2,000 residents to evacuate.’ Explanation – ‘This shows that the flood had direct human impacts, as families were displaced and faced long‑term emotional stress, while emergency services were stretched.’ Link – ‘Such social disruption often drives the need for improved flood defences.’ Practise writing PEEL paragraphs for each of your case studies to internalise the flow.
例如，如果被问到河流洪水的影响，一个 PEEL 段落可以是：观点——“洪水在约克镇造成了严重的社会混乱。”证据——“2015 年 12 月，乌斯河决堤，淹没了 600 户住宅，迫使 2000 名居民疏散。”解释——“这表明洪水造成了直接的人类影响，因为家庭流离失所，面临长期的情绪压力，同时应急服务捉襟见肘。”联系——“这种社会混乱常常推动对改进防洪设施的需求。”为你每个案例研究练习写 PEEL 段落，以将流程内化。
4. Key Themes and Typical Case Study Requirements | 关键主题与典型案例要求
CIE IGCSE Geography syllabus content is organised into three themes: Population and Settlement, The Natural Environment, and Economic Development. Each theme demands at least two contrasting case studies. For instance, the Population theme often requires a case study of a country with a high rate of natural population growth, and another with an ageing population. The Natural Environment theme may require river flooding and coastal erosion examples. Ensure you have a complete set that matches the syllabus table.
CIE IGCSE 地理教学大纲内容分为三大主题：人口与聚落、自然环境与经济发展。每个主题要求至少两个对比的案例研究。例如，人口主题通常需要一个高自然人口增长率国家的案例研究，以及另一个老龄化人口国家的案例研究。自然环境主题可能需要河流洪水和海岸侵蚀的例子。确保你拥有与大纲表格匹配的完整组合。
For Economic Development, you might study a transnational corporation (TNC) and its impacts, and a local economic development project. Tourism, energy, and water resources all fall under this theme. By linking each case study to the correct theme, you will never be caught without an appropriate example. Use the official Cambridge syllabus to check your coverage before the exam.
对于经济发展，你可能学习一个跨国公司及其影响，以及一个当地经济发展项目。旅游、能源和水资源都属于这一主题。通过将每个案例研究与正确的主题关联，你永远不会缺少合适的例子。在考试前使用官方剑桥教学大纲检查你的覆盖范围。
5. Workout 1: Population Dynamics – Nigeria’s Youthful Population | 实战演练1：人口动态——尼日利亚年轻人口结构
Question: For a named country you have studied, explain the causes and consequences of a youthful population. (7 marks)
题目：针对你学过的一个命名国家，解释年轻人口结构的原因和后果。（7 分）
Let us model a high‑scoring answer using Nigeria. First, clearly state your case study: ‘Nigeria, a country in West Africa, has a population where over 43% are under 15 years old.’ Then, outline two causes: high birth rate (5.3 children per woman) linked to cultural preference for large families, early marriage, and low contraceptive use; and declining infant mortality due to improved basic healthcare. For consequences, select both opportunities and challenges: a large future workforce can boost economic growth (demographic dividend), but currently it strains schools and healthcare, leading to overcrowded classrooms and high youth unemployment in cities like Lagos.
让我们用尼日利亚示范一个高得分答案。首先，清楚地陈述你的案例研究：“尼日利亚，一个西非国家，43% 以上的人口年龄在 15 岁以下。”然后，概括两个原因：高出生率（每名妇女 5.3 个孩子）与偏爱大家庭的文化习俗、早婚和低避孕工具使用率有关；以及由于基本医疗改善而下降的婴儿死亡率。对于后果，同时选择机遇和挑战：庞大的未来劳动力可以推动经济增长（人口红利），但目前它给学校和医疗带来压力，导致拉各斯等城市教室拥挤和青年失业率高。
Use specific data: ‘Youth unemployment in Nigeria reached 42.5% in 2020, and pupil‑to‑teacher ratios in rural areas exceed 60:1.’ This detail proves you know the place. Avoid listing; instead, weave statistics into explanatory sentences. End with a brief evaluation, such as ‘although a youthful population can be an asset, Nigeria’s current lack of investment in education limits the potential demographic dividend.’
使用具体数据：“2020 年尼日利亚青年失业率达到 42.5%，农村地区师生比超过 60:1。”这个细节证明了你了解该地。避免罗列；相反，将统计数字编织进解释性句子。以简要评价结束，例如“尽管年轻人口结构可能是一种资产，但尼日利亚目前在教育方面投资不足，限制了潜在的人口红利。”
6. Workout 2: Settlement and Service Provision – Shanghai’s Urban Growth | 实战演练2：聚落与服务提供——上海城市增长
Question: Describe the causes of rapid urbanisation in a named city and explain the problems that result. (7 marks)
题目：描述一个命名城市快速城市化的原因，并解释由此产生的问题。（7 分）
Shanghai is an excellent example. Begin with the city’s location and context: ‘Shanghai, on China’s east coast at the mouth of the Yangtze River, has grown from 10 million people in 1990 to over 24 million today.’ Identify two main causes: rural‑to‑urban migration driven by the promise of manufacturing and service jobs in the Pudong New Area, and natural increase as young migrants start families. Specifically mention the 1990 government decision to open Pudong as a special economic zone, attracting foreign investment. This shows cause‑and‑effect understanding.
上海是一个极好的例子。从城市的位置和背景开始：“上海，位于中国东海岸长江口，人口从 1990 年的 1000 万增长到今天的 2400 多万。”指出两个主要原因：由浦东新区制造业和服务业工作机会驱动的农村向城市迁移，以及年轻移民组建家庭带来的自然增长。特别提到 1990 年政府决定将浦东作为经济特区开放，吸引外资。这表明了因果关系的理解。
For problems, mention housing shortages leading to informal settlements, traffic congestion (Shanghai has over 4 million private cars), and air pollution. Use named places within the city: ‘In areas like Minhang, housing prices have tripled since 2005, forcing low‑income workers to commute over two hours daily.’ Evaluate the effectiveness of the metro expansion in reducing congestion but note it has not solved all issues. This workout teaches you to anchor problems in real places.
关于问题，提及导致非正规住区的住房短缺、交通拥堵（上海有超过 400 万辆私家车）和空气污染。使用城市内的命名地点：“在闵行等地区，自 2005 年以来房价涨了三倍，迫使低收入工人每天通勤超过两小时。”评价地铁扩建在减少拥堵方面的有效性，但指出它没有解决所有问题。这个演练教你将问题锚定在真实地点。
7. Workout 3: Rivers and Coasts – The River Tees Management | 实战演练3：河流与海岸——蒂斯河管理
Question: For a river you have studied, describe the causes of flooding and evaluate the methods used to manage it. (7 marks)
题目：针对你学过的一条河流，描述洪水的原因并评价管理它的方法。（7 分）
The River Tees in north‑east England provides a classic UK case study. Assume the river’s upper course has steep v‑shaped valleys and high rainfall (>1000 mm annually) over impermeable peat soils, which increases runoff. Flooding in the lower course, particularly around Yarm and Stockton‑on‑Tees, occurs when prolonged rain saturates the ground. Mention the 2012 flood where the river discharge reached 200 m³/s, affecting 500 homes.
英格兰东北部的蒂斯河提供了一个经典的英国案例研究。假设河流的上游有陡峭的 V 形山谷，年降水量超过 1000 毫米，落在不透水的泥炭土上，增加了径流。下游的洪水，尤其在亚姆和蒂斯河畔斯托克顿附近，发生在持续降雨使地面饱和时。提及 2012 年的洪水，当时河流流量达到 200 立方米/秒，影响了 500 户家庭。
Management strategies: hard engineering such as the Tees Barrage (built 1995) regulates water levels and prevents tidal flooding, while flood‑relief channels divert excess water. Soft engineering includes afforestation in the upper catchment and flood‑plain zoning. An evaluation is essential: the barrage has been effective in reducing flood risk and created a leisure waterfront, but it was expensive (£54 million) and may disrupt fish migration. Show you can weigh costs and benefits.
管理策略：硬工程如蒂斯拦河坝（建于 1995 年）调节水位并防止潮汐洪水，同时泄洪渠分流多余的水。软工程包括上游集水区植树造林和洪泛区分区。评价至关重要：拦河坝有效降低了洪水风险并创造了休闲水滨，但它造价昂贵（5400 万英镑）并可能干扰鱼类洄游。展示你可以权衡成本与收益。
8. Workout 4: Weather and Climate – Hurricane Katrina | 实战演练4：天气与气候——卡特里娜飓风
Question: For a named tropical storm, describe its impacts and explain how effective the response was. (7 marks)
题目：针对一个命名的热带风暴，描述其影响并解释应对措施的有效性。（7 分）
Hurricane Katrina (2005) is a stark example of a natural hazard in an MEDC. Start with the location: formed over the Bahamas, made landfall in Louisiana and Mississippi as a Category 5 storm. Socio‑economic impacts: 1,800 deaths, mainly from flooding after levees failed in New Orleans; 1 million people displaced; economic cost $125 billion. Environmental impacts: coastal wetland erosion, oil spills from damaged refineries. Distinguish between immediate and long‑term impacts.
卡特里娜飓风（2005 年）是一个 MEDC 自然灾害的鲜明例子。从位置开始：在巴哈马上空形成，以五级风暴登陆路易斯安那州和密西西比州。社会经济影响：1800 人死亡，主要由于新奥尔良堤坝崩溃后的洪水；100 万人流离失所；经济损失 1250 亿美元。环境影响：沿海湿地侵蚀、受损炼油厂的石油泄漏。区分即时影响与长期影响。
Effectiveness of response: the Federal Emergency Management Agency (FEMA) was criticised for slow aid delivery – many residents in the Superdome went without food for days. However, the improved levee system (cost $14.5 billion) completed by 2011 has strengthened flood defences. Mention that early warning systems allowed some evacuation, but vulnerable low‑income communities (e.g. the Lower Ninth Ward) were disproportionately affected. This demonstrates evaluation skills by showing both successes and failures.
应对措施的有效性：联邦紧急事务管理局（FEMA）因援助缓慢而受到批评——超级穹顶体育场的许多居民数日无食物。然而，耗资 145 亿美元于 2011 年完成的改善堤坝系统已加强防洪。提及预警系统使部分疏散成为可能，但脆弱的低收入社区（如第九区下部）受到了不成比例的影响。这通过展示成功和失败来展示评价技能。
9. Workout 5: Economic Activity and Tourism – Tourism in Kenya | 实战演练5：经济活动与旅游——肯尼亚旅游
Question: For a named country, explain how tourism has both advantages and disadvantages for the economy and environment. (7 marks)
题目：针对一个命名国家，解释旅游如何对经济和环境既有优势也有劣势。（7 分）
Kenya is a classic mass tourism case study. Outline why tourists are attracted: wildlife safaris (Maasai Mara, Amboseli National Park), beach holidays along the Indian Ocean coast (Mombasa), and cultural experiences. Economic advantages: tourism contributed 10.4% of Kenya’s GDP in 2019 and created 1.6 million jobs directly and indirectly. Foreign exchange earnings help fund infrastructure. However, leakage – where profits flow back to foreign‑owned tour operators – reduces local benefits.
肯尼亚是一个经典的大众旅游案例研究。概述吸引游客的原因：野生动物观赏（马赛马拉、安博塞利国家公园）、印度洋沿岸海滩假期（蒙巴萨）和文化体验。经济优势：2019 年旅游占肯尼亚 GDP 的 10.4%，并直接和间接创造了 160 万个就业岗位。外汇收入有助于资助基础设施。然而，泄漏——利润流回外资旅游运营商——减少了当地收益。
Environmental disadvantages include soil erosion from safari vehicles in the Maasai Mara, coral reef damage from boat anchors, and water over‑consumption by hotels. Mention a specific example: the construction of hotels along Diani Beach has fragmented turtle nesting sites. Management strategies such as ecotourism lodges (e.g. Ol Pejeta Conservancy) and park entry fees to fund conservation are attempts to mitigate damage. Conclude by weighing the overall sustainability – pros and cons.
环境劣势包括马赛马拉的游猎车辆造成土壤侵蚀、船锚损坏珊瑚礁，以及酒店过度消耗水。提及一个具体例子：迪亚尼海滩沿线酒店的建设分割了海龟筑巢地。生态旅游小屋（如 Ol Pejeta 保护区）和用于资助保护的公园门票等管理策略是减轻损害的尝试。通过权衡整体可持续性——利弊——来结束。
10. Workout 6: Energy and the Environment – Three Gorges Dam | 实战演练6：能源与环境——三峡大坝
Question: For a named large‑scale water or energy project, explain its advantages and disadvantages. (7 marks)
题目：针对一个命名的大规模水利或能源项目，解释其优势与劣势。（7 分）
The Three Gorges Dam on the Yangtze River, China, is the world’s largest hydroelectric power station. Start by placing it: completed in 2012, 2.3 km long, generating 22,500 MW of electricity. Advantages: provides about 10% of China’s electricity, reduces reliance on coal, thus cutting CO₂ emissions by 100 million tonnes per year; also improves navigation upstream, allowing 10,000‑tonne ships to reach Chongqing, boosting trade. Flood control is a major benefit – the dam has reduced the frequency of catastrophic flooding downstream, historically a killer.
中国长江上的三峡大坝是世界上最大的水力发电站。先定位：2012 年完工，全长 2.3 公里，发电量 22500 兆瓦。优势：提供中国约 10% 的电力，减少对煤的依赖，从而每年减少 1 亿吨二氧化碳排放；还改善了上游航运，使万吨级船舶可抵达重庆，促进了贸易。防洪是一大益处——大坝降低了下游灾难性洪水的频率，这在历史上是杀手。
Disadvantages: social – over 1.3 million people were displaced, many forced to relocate to towns with limited farmland; cultural heritage sites were submerged; environmental – siltation behind the dam reduces its storage capacity, worsens water pollution, and riverbank erosion downstream. Use specific numbers: ‘Sediment trapped behind the dam has reduced discharge to 40% of its natural load, impacting the Yangtze River Delta.’ Evaluation is key – state that while the dam provides clean energy, the social and ecological costs remain controversial, and siltation is an ongoing challenge not fully solved.
劣势：社会方面——超过 130 万人被迁移，许多人被迫迁往农田有限的城镇；文化遗产地淹没；环境方面——大坝后淤积降低了库容，加剧了水污染和下游河岸侵蚀。使用具体数字：“大坝后截留的泥沙使输沙量降至自然负荷的 40%，影响了长江三角洲。”评价是关键——说明虽然大坝提供清洁能源，但社会和生态代价仍存争议，且淤积是一个尚未完全解决的持续挑战。
11. Common Mistakes and How to Avoid Them | 常见错误及如何避免
One major mistake is forgetting to name the place early in the answer. Always write the country, city or river name in your first sentence. Another error is listing facts without explanation; always connect data to the question. For example, do not just state ‘Japan has 28% over 65’; explain that this ageing structure increases the dependency ratio and pressures health services. A third pitfall is lack of balance: when the question asks to evaluate, you must present both positive and negative aspects and end with a reasoned judgement.
一个重大错误是忘记在答案开头说出地名。始终在第一句写出国家、城市或河流名称。另一个错误是罗列事实而不解释；始终将数据与问题联系起来。例如，不要只陈述“日本 65 岁以上人口占 28%”；解释这种老龄化结构增加了抚养比，并给医疗服务带来压力。第三个陷阱是缺乏平衡：当题目要求评价时，你必须呈现正面和负面两方面，并以合理的判断结束。
Many students also use the wrong scale of case study. If a question says ‘a country’, do not answer with a city. Also, avoid using generic statements; your case study must be place‑specific. Finally, do not spend too long on one question; in the exam, allocate time proportionate to marks. Practise under timed conditions to develop a sense of pace, so you can write a 7‑mark case‑study answer in about 8-10 minutes.
许多学生还使用了错误规模的案例研究。如果题目要求“一个国家”，不要用一个城市来回答。此外，避免使用笼统陈述；你的案例研究必须是特定地点的。最后，不要在一个问题上花费太长时间；在考试中，按分值分配时间。在限时条件下练习以培养节奏感，使你能够在约 8-10 分钟内写出一份 7 分的案例研究答案。
12. Final Practical Tips for the Exam | 最终考试实战建议
In the weeks before your exam, create a single‑page mind map for each case study, containing the place name, key causes, consequences and responses. Practise sketching location maps to reinforce spatial context. Use past papers to identify the types of questions that appear frequently, and write PEEL paragraphs for each. Peer‑assessment can be powerful: swap sample answers with a friend and check for place specific details. Remember, the examiner wants to see that you have genuinely studied a place, not just memorised a textbook definition.
在考试前几周，为每个案例研究创建一页思维导图，包含地名、关键原因、后果和响应。练习绘制位置简图以强化空间背景。利用往年真题找出高频出现的题型，为每个题型写出 PEEL 段落。同伴互评可以非常有效：与朋友交换样本答案并检查地点特定细节。记住，考官想看到你真正研究过一个地方，而不仅仅是记住了教科书的定义。
On exam day, read the question carefully and underline the command word. Jot down your chosen case study name immediately so you don’t forget. Plan your response for 1‑2 minutes, then write with clarity. If you run out of time, at least list key facts in bullet points – though mark schemes prefer prose, bullet points can still earn marks if relevant. Stay calm, trust your prepared case studies, and treat each question as an opportunity to showcase your geographical understanding.
考试当天，仔细阅读问题并在指令词下划线。立即记下你选择的案例研究名称以免遗忘。花 1-2 分钟规划回答，然后清晰作答。如果时间不够，至少以要点形式列出关键事实——尽管评分方案更偏好连贯段落，但相关要点仍可得分。保持冷静，相信你准备好的案例研究，把每个问题当作展示你地理理解的机会。
