1. What Is a Case Study? | 什么是案例分析？

A case study is an in‑depth investigation of a real‑life event, place or issue in geography. It helps you understand how physical and human processes interact in a specific location. For example, studying a flood event like Boscastle 2004 shows how weather, relief and land use combine to create a hazard.

案例分析是对地理中真实事件、地点或问题的深入调查。它帮助你理解自然和人文过程如何在特定地点相互作用。例如，研究2004年博斯卡斯尔洪水事件可以展示天气、地形和土地利用如何共同形成灾害。

In Edexcel KS3, you are expected to recall key facts, explain causes and effects, and evaluate responses. A strong case study answer moves beyond simple description and demonstrates real geographical understanding.

在Edexcel KS3中，你需要记住关键事实，解释原因和影响，并评估应对措施。一个有力的案例分析答案不仅仅是简单描述，而是展示真正的地理理解。

2. The Structure of a Good Case Study Answer | 好的案例分析答案结构

Every good case study answer follows a logical sequence: introduce the location, describe what happened, explain why it happened, and discuss the consequences and management. Think of it as telling a story with a beginning, middle and end – but all backed by specific evidence.

每个好的案例分析答案都遵循一个逻辑顺序：介绍地点，描述发生了什么，解释为什么发生，并讨论后果和管理。你可以把它想象成讲一个故事，有开头、中间和结尾——但都要有具体的证据支持。

• Location: Give a precise place, region and map reference if possible.
• Causes: Explain the physical and human factors behind the event.
• Effects/impacts: Separate into short‑term and long‑term, and if helpful, into social, economic and environmental.
• Responses/management: Describe what was done and evaluate how successful it was.

• 地点：给出精确的位置、区域，如果可能的话给出地图参考。
• 原因：解释事件背后的自然和人为因素。
• 影响/冲击：分为短期和长期，如果合适，还可以分为社会、经济和环境影响。
• 应对/管理：描述采取了哪些措施，并评估其成功程度。

3. Tip 1: Know Your Place – Location Matters | 技巧一：了解地点——位置很重要

Never start a case study with ‘In a city…’ or ‘Somewhere in the UK…’. Always give a specific, named example and locate it clearly. For instance, ‘Boscastle is a small village on the north coast of Cornwall, south‑west England.’ This shows the examiner you have factual knowledge.

千万不要以“在一个城市……”或“在英国某地……”开始案例分析。始终给出一个具体、有名称的例子，并清楚地定位。例如，“博斯卡斯尔是英格兰西南部康沃尔北海岸的一个小村庄。”这向考官展示了你拥有事实性知识。

Use compass directions, nearby rivers or landmark features to strengthen your location description. Even better, link the location to the causes – e.g. ‘Boscastle lies in a steep‑sided valley, which funnelled heavy rainwater rapidly into the river.’

使用罗盘方位、附近的河流或地标特征来加强你的位置描述。更好的是，将位置与原因联系起来——例如，“博斯卡斯尔位于一个陡峭的山谷中，这使得大量雨水迅速汇入河流。”

---

4. Tip 2: Use Specific Facts and Figures | 技巧二：使用具体的事实和数据

Vague language like ‘a lot of rain’ or ‘many houses were damaged’ will not earn high marks. You must memorise a few key statistics for each case study. For the Boscastle flood, remember: 200 mm of rain fell in 24 hours, 75 cars were washed into the sea, and over 50 buildings were flooded.

模糊的语言，如“大量降雨”或“许多房屋受损”，不会获得高分。你必须记住每个案例研究的几个关键统计数据。对于博斯卡斯尔洪水，记住：24小时内降水量达200毫米，75辆汽车被冲入海中，超过50栋建筑被淹。

The table below shows examples of weak versus strong detail.

Weak Detail / 弱细节	Strong Detail / 强细节
It rained heavily.	200 mm of rain fell in 24 hours.
Many people had to leave their homes.	Over 1000 people were evacuated by helicopter.
The coast is eroding quickly.	The Holderness Coast retreats at an average of 2 metres per year.

5. Tip 3: Explain, Don't Just Describe | 技巧三：解释，而不仅仅描述

A common mistake is to write a description when the question asks for an explanation. Description says what happened; explanation says why it happened. Use words like ‘because’, ‘as a result of’, ‘due to’, and ‘this led to’ to turn description into explanation.

一个常见错误是当问题要求解释时却写了描述。描述说的是发生了什么；解释说的是为什么发生。使用“因为”、“由于”、“导致”等词语，把描述转化为解释。

For example, instead of saying ‘The River Valency flooded in August 2004’, explain ‘The River Valency flooded because 200 mm of rainfall in one day saturated the steep valley slopes, causing rapid surface runoff.’ This shows you understand the physical processes.

例如，不要说“瓦伦西河在2004年8月发生了洪水”，而是解释“瓦伦西河之所以发生洪水，是因为一天内200毫米的降雨使陡峭的谷坡饱和，导致快速的地表径流。”这表明你理解了自然过程。

6. Tip 4: Link Causes, Effects and Responses | 技巧四：关联原因、影响和应对措施

Examiners look for connections between different parts of the case study. Show that the effects were a direct result of the causes, and that the responses were designed to tackle those causes and effects. This chain of reasoning raises the quality of your answer significantly.

考官寻找案例分析不同部分之间的联系。显示出影响是原因的直接结果，且应对措施旨在解决那些原因和影响。这种推理链能显著提高答案的质量。

For the Holderness Coast, you might write: ‘The boulder clay cliffs are easily eroded by storm waves (cause), leading to road collapse and loss of farmland (effects). Hard engineering measures like rock groynes at Mappleton trap sand, but they starve downdrift beaches of sediment, worsening erosion at places like Easington.’ This demonstrates critical thinking.

对于霍尔德内斯海岸，你可以写：“冰川沉积物组成的悬崖容易被风暴波浪侵蚀（原因），导致道路坍塌和农田损失（影响）。马普尔顿的岩石防波堤等硬工程措施捕获沙子，但会使下游海滩缺乏沉积物，加剧伊辛顿等地的侵蚀。”这展示了批判性思维。

7. Case Study Example 1: River Flooding – Boscastle 2004 | 案例分析示例1：河流洪水——博斯卡斯尔2004年

Boscastle is a tourist village in Cornwall, England, lying at the confluence of three rivers: the Valency, Jordan and Paradise. On 16 August 2004, an exceptional downpour led to a flash flood that caused huge damage. The synoptic weather chart showed a slow‑moving low‑pressure system drawing moist air from the Atlantic, which was forced to rise over the Cornish high ground.

博斯卡斯尔是英格兰康沃尔的一个旅游村庄，位于瓦伦西河、乔丹河和天堂河三条河流的交汇处。2004年8月16日，一场特大暴雨引发了突发洪水，造成了巨大损失。天气图显示一个移动缓慢的低压系统从大西洋吸入湿润空气，空气被迫在康沃尔高地抬升。

Physical causes: steep V‑shaped valley, thin soils, impermeable slate bedrock, and intense rainfall (200 mm in 24 hours). Human causes: urbanisation along the narrow valley floor, bridges causing debris blockages, and limited flood warnings. Effects included destruction of the visitor centre, 75 cars washed into the harbour, and over 1000 people airlifted to safety.

自然原因：陡峭的V形山谷、薄土层、不透水的板岩基岩，以及强降雨（24小时200毫米）。人为原因：狭窄谷底的城市化、桥梁造成碎片堵塞，以及有限的洪水预警。影响包括游客中心被毁、75辆汽车被冲入港口、超过1000人被直升机运送到安全地带。

Responses: a £4.6 million flood defence scheme was built, including a wider river channel, a new culvert and flood walls. The Environment Agency now monitors river levels closely. The scheme has been mostly successful, though some locals argue it has altered the village’s character.

应对措施：建设了一个价值460万英镑的防洪工程，包括加宽的河道、新的涵洞和防洪墙。环境署现在密切监测河流水位。该工程大部分是成功的，尽管一些当地人认为它改变了村庄的特色。

8. Case Study Example 2: Coastal Erosion – Holderness Coast | 案例分析示例2：海岸侵蚀——霍尔德内斯海岸

The Holderness Coast in East Yorkshire is the fastest‑eroding coastline in Europe. The cliffs are made of soft boulder clay (till), which is easily worn away by wave action, especially during winter storms. The prevailing north‑easterly winds drive powerful waves straight 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。悬崖由松软的冰川沉积物（冰碛物）组成，极易被波浪作用侵蚀，尤其是在冬季风暴期间。盛行的东北风将强劲的波浪直接推向海岸。

Erosion rates can reach 10 metres per year in unprotected areas, such as near Easington. Villages like Skipsea and Withernsea have lost many buildings to the sea. The map of the coast shows a distinctive sweeping curve, with material transported south by longshore drift forming Spurn Head spit at the mouth of the Humber Estuary.

在未设防的地区，如伊辛顿附近，侵蚀速率可达每年10米。斯基普西和威瑟恩西等村庄已有许多建筑物被大海吞没。该海岸的地图显示出特征性的弧形曲线，物质沿纵向漂流向南输送，在亨伯河口形成了斯珀恩角沙嘴。

Management includes hard engineering at Mappleton (rock groynes and revetments) and at Withernsea (sea wall). However, these defences are expensive and cause increased erosion further south. The policy of ‘managed realignment’ means some farmland is surrendered to the sea, creating saltmarsh habitat while reducing costs.

管理措施包括马普尔顿的硬工程（岩石防波堤和护岸）以及威瑟恩西的海墙。然而，这些防御措施成本高昂，并导致更南部的侵蚀加剧。“管理式退让”的政策意味着部分农田被让给大海，在减少成本的同时创造了盐沼栖息地。

9. Case Study Example 3: Urbanisation – London Docklands | 案例分析示例3：城市化——伦敦码头区

In the 19th century, London Docklands was the world’s busiest port. By the 1970s, containerisation and larger ships made the docks obsolete. The area suffered from dereliction, unemployment (over 60% in some wards), lack of basic services and poor housing. This is a classic example of urban decline and regeneration.

19世纪，伦敦码头区是世界上最繁忙的港口。到了20世纪70年代，集装箱化和更大的船只使码头被废弃。该地区遭受废弃、失业（某些区域超过60%）、缺乏基本服务和住房条件差的问题。这是城市衰退与再生的典型例子。

The London Docklands Development Corporation (LDDC) was set up in 1981 to regenerate 22 km² of East London. Key projects included the Canary Wharf financial district (now a major global financial centre), over 25,000 new homes, the Docklands Light Railway (DLR), London City Airport and new green spaces.

伦敦码头区发展公司（LDDC）于1981年成立，旨在对22平方公里的东伦敦进行再生。关键项目包括金丝雀码头金融区（现为全球主要金融中心）、超过2.5万套新住房、码头区轻轨（DLR）、伦敦城市机场和新的绿色空间。

Successes: thousands of jobs created, improved transport, attractive waterfront housing. Criticisms: new jobs often went to skilled outsiders, not the original dockers; rising property prices displaced established communities; and some felt the area lost its traditional character. This case study highlights the uneven benefits of regeneration.

成功之处：创造了数千个工作岗位，改善了交通，建造了迷人的水岸住宅。批评：新工作往往由外来技术工人获得，而非原来的码头工人；房价上涨迫使原有社区搬离；一些人觉得该地区失去了传统特色。这个案例分析突显了再生的收益不均。

10. Practice Questions and Model Answers | 练习题与模考答案

Below are three typical KS3 Edexcel‑style questions. Try to answer them before reading the model answers. Remember to use our tips: location, specific facts, explanation and links.

以下是三个典型的KS3 Edexcel风格的问题。在阅读模考答案前，先尝试回答。记住使用我们的技巧：位置、具体事实、解释和关联。

Q1: Using a named example, explain how human activities can increase the risk of river flooding. (4 marks)

Q1：以一个具体例子说明人类活动如何增加河流洪水的风险。（4分）

Model answer: In Boscastle, human factors worsened the 2004 flood. Buildings and bridges on the River Valency trapped debris, creating temporary dams that suddenly burst (1). The narrow street layout channelled floodwater at high speed (1). Urbanisation on the floodplain reduced infiltration, increasing surface runoff (1). Before the event, there were few warning systems and limited land use planning, meaning residents were unprepared (1).

模考答案：在博斯卡斯尔，人为因素加剧了2004年的洪水。瓦伦西河上的建筑和桥梁困住了杂物，形成临时水坝，随后突然溃决（1分）。狭窄的街道布局将洪水高速引导（1分）。洪泛平原上的城市化减少了渗透，增加了地表径流（1分）。事件发生前，预警系统很少，土地利用规划有限，居民准备不足（1分）。

Q2: Explain why the Holderness Coast is eroding so rapidly. (4 marks)

Q2：解释为什么霍尔德内斯海岸侵蚀如此迅速。（4分）

Model answer: The cliffs are made of soft boulder clay, which is unconsolidated and easily eroded by wave action (1). The prevailing north‑easterly waves have a long fetch across the North Sea, arriving with high energy (1). Defences at Mappleton, such as rock groynes, trap sand but starve beaches further south of sediment, increasing erosion at places like Easington (1). Rising sea levels due to climate change add to the problem by allowing waves to reach further inland (1).

模考答案：悬崖由松软的冰碛物组成，这种物质未固结，易被波浪侵蚀（1分）。盛行的东北方向的波浪在北海有长吹程，到达时能量很高（1分）。马普尔顿的防御工事，如岩石防波堤，截留了沙子，但使更南部的海滩缺乏沉积物，加剧了伊辛顿等地的侵蚀（1分）。气候变化导致海平面上升，海浪可到达更内陆的区域，使问题雪上加霜（1分）。

11. Key Takeaways and Final Tips | 关键总结与最后提示

Always start with a clear location. Use specific numbers – they are your evidence. Structure your answer by separating causes, effects and responses. Show how different factors are linked. For each case study, memorise two or three powerful facts you can drop into any question. Finally, practise writing timed answers; most KS3 case study questions will be worth 4‑6 marks and require about 6‑8 minutes of writing.

始终以明确的地点开头。使用具体的数字——它们是你的证据。通过区分原因、影响和应对措施来组织答案。展示不同因素是如何关联的。对于每个案例分析，记住两到三个有力的、可以用于任何问题的事实。最后，练习限时答题；大多数KS3案例分析题目分值在4 – 6分之间，大约需要6 – 8分钟的书写时间。

Remember, geography case studies are not just about memorising facts – they are about understanding real places and real people. The more you can visualise the location and its story, the easier it will be to write a confident, well‑grounded answer. Keep reviewing your notes and linking new case studies to the ones you already know.

记住，地理案例分析不仅仅是记忆事实——它们是关于理解真实的地方和真实的人。你越能想象那个地点和它的故事，就越容易写出自信、有根据的答案。不断复习笔记，并将新的案例分析与你已经知道的内容联系起来。
