📚 IGCSE WJEC Geography: Case Study Exam Practice | IGCSE WJEC 地理：案例分析实战演练
Case study questions in IGCSE WJEC Geography reward precise, located knowledge, not vague generalisations. This article gives you a repeatable toolkit for turning case study revision into high-band exam answers, with worked examples from key topics.
IGCSE WJEC 地理中的案例研究题奖励精确的、有地点的知识，而不是模糊的概括。本文为你提供一套可重复使用的工具包，将案例研究复习转化为高分答案，并配有重点主题的实战示例。
1. Why Case Studies Matter | 为什么案例研究重要
In WJEC IGCSE Geography, a case study is a real place used to illustrate a process, issue or management strategy. You are expected to recall specific facts, figures, names and locations, then apply them to the question set.
在 WJEC IGCSE 地理中，案例研究是用于说明某种过程、问题或管理策略的真实地点。考试要求你回忆具体事实、数据、名称和位置，并将其应用到所给题目中。
Examiners look for located detail: a river flood case study without a named river or a dated event will stay in the lower mark bands. Generic answers such as ‘people leave the area’ do not show the application skill WJEC rewards.
考官看重有地点的细节：如果河流洪水案例没有具体河流名称或事件日期，答案就会停留在低分段。像“人们离开该地区”这样的泛泛回答无法展示 WJEC 所奖励的应用能力。
Case studies also allow you to evaluate management. A strong answer compares the successes and failures of a real scheme, using place-specific evidence rather than repeating textbook labels.
案例研究还能让你评估管理措施。高分答案会比较真实方案的成功与失败，使用特定地点的证据，而不是重复课本上的标签。
2. Decoding WJEC Command Words | 解析 WJEC 指令词
Different command words in case study questions tell you how much evaluation is needed. ‘Describe’ asks for what and where; ‘explain’ asks for causes and processes; ‘evaluate’ asks for judgement about success or sustainability.
案例研究题中的不同指令词告诉你需要多少评估。“描述”要求回答是什么和在哪里；“解释”要求回答原因和过程；“评估”要求对成功与否或可持续性作出判断。
For a 9-mark question, WJEC often expects a developed answer with at least two well-supported points and a named case study. Using the PEE structure — Point, Evidence, Explanation — keeps your answer focused.
对于 9 分题，WJEC 通常要求给出充分展开的答案，至少包含两个有证据支撑的要点和一个具名案例。使用 PEE 结构——观点、证据、解释——可以让答案保持聚焦。
- Describe: state the pattern, trend or feature of the named place.
- 解释：说明该地点中模式、趋势或特征的表现。
- Explain: give reasons, processes or mechanisms causing the pattern.
- 解释：给出导致该模式的原因、过程或机制。
- Evaluate: weigh strengths and weaknesses, then reach a judgement.
- 评估：权衡优点与缺点，然后得出结论。
Always match the depth of your case study detail to the mark tariff. A 2-mark definition needs one clear fact; a 9-mark evaluation needs developed paragraphs, not a list.
始终将案例细节的深度与分值匹配。2 分的定义题只需一个清晰事实；9 分的评估题需要展开的段落，而不是列表。
3. The Five-Step Case Study Toolkit | 五步案例工具包
Use the same five-step toolkit for every case study you revise: Location, Causes, Impacts, Responses and Evaluation. This gives your answer a logical structure and ensures you do not miss a mark-bearing element.
对每一个案例复习都使用相同的五步工具包：位置、原因、影响、响应和评估。这使你的答案具有逻辑结构，并确保不会遗漏得分要素。
Location: name the place, country, region or river, and locate it on a map. For example, ‘Holderness Coast, East Yorkshire, UK, facing the North Sea’ is better than ‘a coast in the UK’.
位置：说出地点、国家、地区或河流，并在地图上定位。例如，“英国约克郡东部的霍尔德内斯海岸，面向北海”比“英国的一个海岸”更好。
Causes: give the physical or human processes creating the issue. Include data such as rainfall totals, tectonic magnitude, migration rates or GDP per capita where relevant.
原因：说明产生该问题的自然或人文过程。包括相关数据，如降雨量、震级、迁移率或人均 GDP。
Impacts: split impacts into social, economic and environmental categories. Always use specific examples, such as ‘2,000 homes flooded’ rather than ‘many homes’.
影响：将影响分为社会、经济和环境三类。始终使用具体例子，如“2000 户房屋被淹”，而不是“许多房屋”。
Responses: describe short-term and long-term management. Name schemes, costs, organisations and dates where possible.
响应：描述短期和长期管理措施。尽可能说出方案名称、成本、机构和日期。
Evaluation: judge how successful or sustainable the responses were. Identify winners and losers, and support your judgement with evidence.
评估：判断响应措施的成功程度或可持续性。指出受益者和受损者，并用证据支持你的判断。
4. River Flooding Case Study: River Severn, UK | 河流洪水案例：英国塞文河
The River Severn in the UK flooded severely in July 2007 after 24 hours of extreme rainfall. Tewkesbury in Gloucestershire was cut off when the Severn and Avon burst their banks, making the town an island.
英国塞文河在 2007 年 7 月经历极端降雨后发生严重洪水。格洛斯特郡的蒂克斯伯里因塞文河与埃文河决堤而被围困，城镇变成孤岛。
Physical causes included saturated ground from previous wet weather and a very slow-moving depression that delivered over 120 mm of rain in 48 hours. Human causes included building on floodplains and older drainage systems with limited capacity.
自然原因包括前期多雨导致土壤饱和，以及一个移动缓慢的低压系统在 48 小时内带来超过 120 毫米降雨。人为原因包括在洪泛平原上建设房屋，以及老旧排水系统容量有限。
Impacts were severe: 48,000 homes and businesses lost power, thousands of people were evacuated, and damage exceeded £3 billion. The Mythe water treatment works flooded, leaving 140,000 people without clean water for over a week.
影响十分严重：48,000 户家庭和企业断电，数千人被疏散，损失超过 30 亿英镑。迈斯水处理厂被淹，导致 14 万人超过一周没有清洁饮用水。
Responses included improved flood warnings, the construction of demountable barriers, and dredging of the Severn. However, evaluation shows that some measures were only activated after the event, so their value was reactive rather than preventive.
应对措施包括改进洪水预警、建造可拆卸防洪屏障以及疏浚塞文河。然而，评估表明一些措施是在事件发生后才启用的，因此其价值是被动的，而非预防性的。
5. Coastal Management Case Study: Holderness Coast | 海岸管理案例：霍尔德内斯海岸
Holderness Coast in East Yorkshire, UK, is one of Europe’s fastest eroding coastlines, with average rates of about 2 metres per year. The cliffs are made of soft boulder clay, which is easily attacked by waves from the North Sea.
英国东约克郡的霍尔德内斯海岸是欧洲侵蚀最快的海岸线之一，平均每年侵蚀约 2 米。悬崖由柔软的冰碛黏土组成，容易被北海海浪侵蚀。
The village of Mappleton was protected in 1991 by two rock groynes and a revetment at a cost of about £2 million. This protected the village and the B1242 road, but starved beaches further south of sediment.
1991 年，马普尔顿村修建了两座岩石丁坝和一道护岸，耗资约 200 万英镑。这项工程保护了村庄和 B1242 公路，但使更南边的海滩缺乏泥沙补给。
At Great Cowden, south of Mappleton, erosion increased because the groynes trapped sediment that would have moved south by longshore drift. This shows that hard engineering can protect one place while creating problems elsewhere.
在马普尔顿以南的大考登，由于丁坝截留了本应通过沿岸漂移向南移动的泥沙，侵蚀反而加剧。这表明硬工程可能保护了一个地方，却给其他地方制造问题。
An evaluation of coastal management on Holderness shows that cost-benefit analysis is essential. Protecting a small village may be justified locally, but the environmental cost for the wider coastline must be considered.
对霍尔德内斯海岸管理的评估表明，成本效益分析至关重要。保护一个小村庄在当地可能是合理的，但必须考虑对更广泛海岸线的环境代价。
6. Urban Challenges Case Study: Lagos, Nigeria | 城市挑战案例：尼日利亚拉各斯
Lagos is a megacity in Nigeria with an estimated population of over 21 million. It attracts rural-to-urban migrants because of better job opportunities, but the city faces massive pressure on housing, transport and sanitation.
拉各斯是尼日利亚的一座特大城市，估计人口超过 2100 万。由于就业机会更好，它吸引了大量农村到城市的移民，但城市在住房、交通和卫生方面面临巨大压力。
Makoko is a well-known informal settlement built on stilts over the lagoon. Many residents are employed in fishing or informal trade, but the area lacks secure tenure, clean piped water and formal waste collection.
马科科是著名的非正式定居点，建在泻湖上的高脚屋中。许多居民从事渔业或非正规贸易，但该地区缺乏土地保障、清洁自来水和正规垃圾收集服务。
Responses include the Eko Atlantic project, a new city being built on reclaimed land to the east of Victoria Island. It is designed to house 250,000 people and provide modern offices, but it mainly serves high-income groups.
应对措施包括埃科大西洋项目，该项目在维多利亚岛以东的填海土地上建设一座新城。它计划容纳 25 万人并提供现代化办公空间，但主要服务于高收入群体。
Evaluation reveals that while Eko Atlantic may reduce flood risk and attract investment, it does not solve the housing crisis for the poorest residents. Sustainable urban management requires upgrading existing informal settlements as well.
评估表明，虽然埃科大西洋可能降低洪水风险并吸引投资，但它并不能解决最贫困居民的住房危机。可持续的城市管理还需要升级现有的非正式定居点。
7. Population Change Case Study: Japan | 人口变化案例：日本
Japan is a high-income country facing rapid population ageing and a declining birth rate. In 2020, around 28% of the population was aged 65 or over, and the total fertility rate was about 1.3, well below replacement level.
日本是一个高收入国家，正面临人口快速老龄化和出生率下降的问题。2020 年，约 28% 的人口年龄在 65 岁及以上，总和生育率约为 1.3，远低于更替水平。
Causes include better healthcare, longer life expectancy, high costs of raising children, and a work culture that makes family life difficult. Many young adults delay marriage or choose not to have children.
原因包括医疗条件改善、预期寿命延长、养育子女成本高，以及使家庭生活困难的工作文化。许多年轻人推迟结婚或选择不生育。
Impacts include a shrinking workforce, rising pension and healthcare costs, and rural depopulation as young people move to large cities. Some schools have closed due to a lack of children.
影响包括劳动力萎缩、养老金和医疗成本上升，以及年轻人迁往大城市导致的农村人口减少。一些学校因缺乏儿童而关闭。
Responses include raising the retirement age, promoting robotics and automation in care homes and factories, and offering financial incentives for families. Evaluation shows these measures slow the decline but have not reversed the long-term trend.
应对措施包括提高退休年龄、在养老院和工厂推广机器人与自动化，以及为家庭提供经济激励。评估表明，这些措施减缓了下降趋势，但尚未扭转长期变化。
8. Tectonic Hazards Case Study: Haiti vs New Zealand | 构造灾害案例：海地与新西兰对比
Comparing two earthquakes shows that wealth and preparedness, not just magnitude, determine disaster impact. Haiti’s earthquake in January 2010 had a magnitude of 7.0 and killed an estimated 220,000 people, while the Christchurch earthquake in February 2011 had a magnitude of 6.3 and killed 185.
比较两次地震可以看出，财富和备灾能力，而不仅仅是震级，决定灾害影响。2010 年 1 月海地地震震级为 7.0，约 22 万人死亡；2011 年 2 月基督城地震震级为 6.3，死亡人数为 185。
Haiti had weak building codes, widespread poverty and limited emergency services, so poorly built concrete structures collapsed. New Zealand had strict building codes, earthquake insurance and well-trained search and rescue teams.
海地建筑规范薄弱、贫困普遍、应急服务有限，因此建造不良的混凝土建筑倒塌。新西兰则有严格的建筑规范、地震保险和训练有素的搜救队伍。
The difference in impacts is a textbook example of the disaster risk equation: risk is a product of hazard and vulnerability. Lower vulnerability in New Zealand produced far fewer deaths despite strong shaking.
两者的影响差异是灾害风险公式的教科书式例子：风险是危险性与脆弱性的乘积。新西兰较低的脆弱性使其在强烈震动下死亡人数少得多。
An evaluation of responses shows that international aid played a vital role in Haiti, but coordination was poor and cholera spread in camps. New Zealand’s self-sufficiency allowed faster recovery, but liquefaction caused costly damage in Christchurch.
对响应措施的评估表明，国际援助在海地发挥了关键作用，但协调不力，霍乱在营地中蔓延。新西兰的自给自足使恢复更快，但液化现象给基督城造成了高昂损失。
9. Economic Development Case Study: China | 经济发展案例：中国
China provides a strong case study of rapid economic growth through industrialisation and global trade. Since the 1980s, Special Economic Zones such as Shenzhen have attracted foreign investment and transformed the economy.
中国为通过工业化和全球贸易实现快速经济增长提供了一个强有力的案例。自 20 世纪 80 年代以来，深圳等经济特区吸引了外国投资，改变了经济面貌。
Shenzhen grew from a small fishing town to a city of over 17 million people and became a global technology hub. Cheap labour, improved infrastructure and government policy were key pull factors for transnational corporations.
深圳从一个小渔村成长为人口超过 1700 万的城市，并成为全球科技中心。廉价劳动力、改善的基础设施和政府政策是吸引跨国公司的关键因素。
Benefits include rising GDP per capita, falling extreme poverty and better access to education and healthcare. However, costs include air and water pollution, regional inequality between coastal and inland areas, and an ageing workforce.
好处包括人均 GDP 上升、极端贫困减少以及教育和医疗机会改善。然而，代价包括空气和水污染、沿海与内陆之间的区域不平等，以及劳动力老龄化。
Evaluation of China’s development shows a trade-off between rapid economic growth and environmental quality. Recent policies to reduce carbon emissions and develop renewable energy aim to make growth more sustainable.
对中国发展的评估表明，快速经济增长与环境质量之间存在权衡。近期减少碳排放和发展可再生能源的政策，旨在使增长更具可持续性。
10. Fieldwork Skills: Applying Case Study Logic | 田野调查技巧：应用案例逻辑
WJEC IGCSE Geography fieldwork questions often ask you to link your own data collection to a case study concept. Using the five-step toolkit helps you explain why you collected certain data and what it showed.
WJEC IGCSE 地理的田野调查题经常要求你将自己的数据收集与案例研究概念联系起来。使用五步工具包有助于解释你为何收集某些数据及其结果。
For a river study, you might measure channel width, depth and velocity at three sites downstream. Presenting this data in a table and linking it to the Bradshaw model shows understanding of river processes.
在河流研究中，你可以在下游三个地点测量河道宽度、深度和流速。用表格呈现数据，并将其与布拉德肖模型联系起来，展示对河流过程的理解。
| Site | 1: Upper course | 2: Middle course | 3: Lower course |
| Mean width (m) | 2.4 | 6.1 | 10.8 |
| Mean depth (m) | 0.12 | 0.31 | 0.58 |
Evaluation of fieldwork methods is essential. You should discuss limitations such as only taking one reading per site, or taking measurements on different days, and suggest improvements such as repeating measurements and using calibrated equipment.
对田野调查方法的评估至关重要。你应该讨论局限性，例如每个地点只读取一次数据，或在不同日期进行测量，并提出改进建议，如重复测量和使用校准设备。
11. Structuring a 9-Mark Case Study Answer | 构建 9 分案例题答案
For a 9-mark WJEC case study question, use the following structure: a short introduction naming the case study and defining key terms, two or three developed body paragraphs, and a conclusion that makes a clear judgement.
对于 WJEC 9 分案例研究题，使用以下结构：简短引言，说出案例名称并定义关键术语；两到三个展开的主体段落；以及一个作出明确判断的结论。
Each body paragraph should follow PEE: Point, Evidence, Explanation. For example, ‘Mappleton’s groynes have protected the village, shown by the cliff line retreating less than 1 metre since 1991, because they trap sediment and reduce wave energy.’
每个主体段落应遵循 PEE：观点、证据、解释。例如，“马普尔顿的丁坝保护了村庄，证据是自 1991 年以来崖线后退不到 1 米，这是因为丁坝截留泥沙并削弱波浪能量。”
Always leave time for a conclusion that makes a judgement. Phrases such as ‘Overall, the scheme was mainly successful for local residents but created problems further along the coast’ show evaluative skill.
始终留出时间写出作出判断的结论。像“总体而言，该方案对当地居民基本是成功的，但给海岸更远处带来了问题”这样的表述，展示了评估能力。
Avoid writing everything you know about a case study. Read the question carefully and only include material that answers the command word and focus of the question.
避免把你知道的关于案例的一切都写下来。仔细审题，只包含能够回应指令词和题目重点的内容。
12. Common Pitfalls and Final Check | 常见误区与最终检查
The most common pitfall in case study questions is using generic place names like ‘an LEDC’ or ‘a city in Asia’. WJEC penalises vague answers because they do not show located knowledge.
案例研究题中最常见的误区是使用“一个欠发达国家”或“亚洲某城市”这样的泛泛地名。WJEC 会因这类模糊答案扣分，因为它们没有展示有地点的知识。
Another mistake is listing impacts without explanation. Saying ‘many people lost homes’ does not explain why or how serious it was. Use figures, names and dates to add precision.
另一个错误是罗列影响而不加解释。说“许多人失去家园”没有解释原因或严重程度。使用数字、名称和日期来增加精确度。
Before the exam, make revision cards for five or six contrasting case studies covering rivers, coasts, hazards, urban issues, population and economic development. Include at least three specific facts for each of the five toolkit steps.
考试前，为五到六个对比鲜明的案例制作复习卡片，涵盖河流、海岸、灾害、城市问题、人口和经济发展。每个五步工具包步骤至少包含三个具体事实。
In the final minutes, check that you have named every case study, used relevant data and written a judged conclusion. This final check often moves an answer from the middle band into the top band.
在最后几分钟，检查你是否说出了每个案例的名称、使用了相关数据，并写出了有判断的结论。这一最终检查常常使答案从中分段进入高分段。
