📚 Year 7 WJEC Geography: Case Study Practical Exercises | 七年级WJEC地理：案例分析实战演练
Case studies lie at the heart of the WJEC Year 7 geography curriculum. They bridge the gap between classroom theory and the real world, helping you develop the skills to observe, describe, explain and evaluate geographical patterns and processes. This article presents a series of hands-on case study exercises designed to build your confidence in analysing places, environments and human interactions. Each exercise includes background information, data to work with and guiding questions, much like those you will encounter in your assessments.
案例学习是WJEC七年级地理课程的核心。它们把课堂理论与现实世界连接起来，帮助你培养观察、描述、解释和评估地理规律与过程的能力。本文提供了一系列动手操作的案例研究练习，旨在建立你分析地点、环境和人类互动的信心。每项练习都包含背景信息、需要处理的数据以及引导性问题，与你在评估中会遇到的题型非常相似。
1. Understanding Case Studies in Geography | 理解地理案例分析
A geographical case study is an in-depth investigation of a real place, event or issue. It allows you to apply general knowledge to a specific context. When you work through a case study, you should think about location, physical and human features, causes and effects, and possible solutions or changes over time. The WJEC exam board expects you to use named examples and to support your answers with precise evidence from the case.
地理案例研究是对真实地点、事件或问题进行的深入调查。它让你能够将一般知识应用到具体情境中。当你分析一个案例时，你应该思考位置、自然与人文特征、原因和影响，以及可能的解决方案或随时间发生的变化。WJEC考试局要求你使用有具体名称的例子，并用案例中的准确证据来支持你的回答。
Good case study practice involves more than just memorising facts. You need to be able to describe patterns shown on maps and graphs, explain why something happens there, and compare different places. The following exercises will train you in exactly these skills, using realistic scenarios drawn from the Year 7 specification: rivers, coasts, settlements, weather, climate and ecosystems.
好的案例研究练习可不仅仅是记住事实。你需要能够描述地图和图表所显示的模式，解释为什么某件事会在那里发生，并且能够比较不同的地方。接下来的练习将使用选自七年级课程的真实情境——河流、海岸、定居点、天气、气候和生态系统，来训练你的这些技能。
2. Case Study 1: River Landforms – Meanders and Oxbow Lakes | 案例1：河流地貌——曲流与牛轭湖
Imagine a river flowing across a wide, flat floodplain. Over time, the force of the water erodes the outer bank of a bend and deposits sediment on the inner bank. This makes the bend more pronounced, forming a meander. Eventually, the neck of the meander can be cut through during a flood, leaving a crescent‑shaped oxbow lake beside the main channel. These features are common in the middle and lower courses of rivers such as the River Severn in the UK.
想象一条河流经宽广平坦的泛滥平原。随着时间的推移，水流的力量侵蚀弯道外侧的河岸，同时将沉积物堆积在内侧河岸上。这使得弯道变得更加明显，形成了曲流。最终，在一次洪水期间，曲流的颈部可能会被冲开，在主河道旁留下一个新月形的牛轭湖。这类特征在英国塞文河等河流的中下游十分常见。
Study the description below and sketch a simple plan view to label the river cliff, slip‑off slope, fastest flow, slowest flow and the likely position of a future oxbow lake. This will help you visualise the process sequence that often appears in exam questions.
阅读下面的描述，并绘制一个简单的平面示意图，标注出河流陡岸、滑走坡、流速最快处、流速最慢处以及未来可能形成牛轭湖的位置。这将帮助你直观地理解考试中经常出现的过程顺序。
- The river bends sharply to the right. The outer bank (on the right) is being undercut and has a steep river cliff.
- 河流急剧向右弯曲。外侧河岸（右侧）正在受到掏蚀，形成了陡峭的河流陡岸。
- The inner bank (on the left) is gently sloping and made of sand and gravel – a slip‑off slope.
- 内侧河岸（左侧）坡度平缓，由沙子和砾石构成——即滑走坡。
- The fastest current hugs the outer bank; the slowest water is on the inside of the bend.
- 流速最快的水流紧贴外侧河岸；最慢的水流则位于弯道内侧。
- A narrow neck of land only about 20 metres wide separates two parts of the bend. This is where a breakthrough could occur.
- 一处仅有约20米宽的狭窄颈部将弯道的两部分隔开，这里就是可能发生决口的地方。
3. Exercise: Interpreting a River Valley Map | 练习：解读河谷地图
A simplified contour map of a river valley shows spot heights and the river's course. You should practise identifying V‑shaped valleys in the upper course and wider valleys with meanders further downstream. Look at the spacing of contours: closely packed contours indicate steep slopes, while widely spaced contours show gentle gradients.
一幅简化的河谷等高线地图显示了各个点的高程和河流的走向。你应该练习在上游识别出V形谷，在下游识别出有曲流的宽阔河谷。观察等高线的疏密：等高线密集表示陡坡，等高线稀疏则表示缓坡。
Exercise: Imagine a map where a river flows from north to south. In the northern section, contour lines are very close together and the river follows a straight path within a narrow valley. In the south, contours are spaced far apart and the river has large bends. Use this description to answer three key questions:
练习：想象一幅地图，有一条河自北向南流淌。在北部，等高线非常密集，河流在狭窄的河谷中沿着一条笔直的路径流动。在南部，等高线间距很大，河流出现了大型弯道。请利用这段描述回答三个关键问题：
- Where is the gradient steepest? How do you know?
- 坡度最陡的地方在哪里？你是如何判断的？
- Explain why the river has a different shape in the southern part.
- 解释一下为什么河流在南部的形态不同。
- Predict what fluvial landform might eventually develop at the tightest bend.
- 预测在最紧凑的弯道处最终可能形成何种河流地貌。
When you write your answers, always refer directly to the map evidence – for example, 'the closely packed contours in the north indicate a steep gradient, which gives the river more energy for vertical erosion.' This technique is essential for AO3 skill marks.
写出答案时，要始终直接引用地图上的证据——例如，“北部密集的等高线表明坡度陡峭，这给河流带来了更多进行下切侵蚀的能量。”这一技巧对于获得AO3技能分至关重要。
4. Case Study 2: Coastal Erosion and Management | 案例2：海岸侵蚀与管理
Many stretches of the British coastline are retreating because of erosion. In a case study of a village like Happisburgh in Norfolk, soft boulder clay cliffs are being worn away by wave action, especially during storms. Houses have fallen into the sea and roads have been lost. This raises difficult questions about how, or if, the coast should be protected.
英国许多海岸线正因侵蚀而后退。以诺福克郡的哈皮斯堡村为例，柔软的大块黏土悬崖正被海浪作用侵蚀，尤其在暴风雨期间更为严重。房屋已坠入大海，道路也已消失。这引发了关于应该如何保护海岸线，甚至是否应该保护的难题。
The following table shows estimated annual erosion rates and the cost of different management strategies. Use it to practise comparing options and justifying a decision, just as a coastal manager would.
下表显示了估计的年侵蚀率以及不同管理策略的成本。请利用该表来练习比较各种方案并论证一个决策，就像海岸管理者所做的那样。
| Management Option | Annual Erosion Rate (m/year) | Cost over 10 years (GBP) | Side Effects |
| Do nothing (managed retreat) | 2.5 | 50 000 (compensation) | Loss of farmland and homes |
| Wooden groynes | 0.8 | 2 500 000 | Starves beaches further down‑drift |
| Sea wall | 0.1 | 8 000 000 | Destroys natural beach habitat |
5. Exercise: Comparing Coastal Protection Methods | 练习：比较海岸保护方法
Using the table above, write a short paragraph explaining which method you think is most suitable for a small village with 80 houses, a primary school and a nature reserve. Consider both the costs and the environmental impacts. You are expected to show balanced reasoning – for instance, a sea wall is very effective but expensive and harmful to wildlife, while doing nothing saves money but destroys the community.
利用上表，写一个简短的段落，解释你认为哪种方法最适合一个有80户住房、一所小学和一个自然保护区的小村庄。要同时考虑成本和环境影响。你的回答需要展示平衡的推理——例如，海堤非常有效，但造价昂贵且对野生动物有害；而什么都不做虽然省钱，却会毁掉社区。
Then, extend the exercise by drawing a line graph showing how the cliff position would change under each option over 50 years. Label your x‑axis 'Years' and y‑axis 'Distance from cliff edge to village (m)'. Start with an initial distance of 100 m. This visual representation will help you see why some communities choose to relocate rather than pay for expensive defences.
然后，通过绘制折线图来扩展练习，显示在50年内每种方案下悬崖位置的变化。在x轴上标注“年份”，在y轴上标注“从悬崖边缘到村庄的距离（米）”。以初始距离100米为起点。这种可视化的表示方法将帮助你理解为什么一些社区选择搬迁，而不是支付昂贵的防护费用。
6. Case Study 3: Urban Growth – A Local Town | 案例3：城市扩张——当地小镇
Urban areas grow for many reasons, including population increase, migration and economic opportunities. Consider a market town called 'Weldon' that has expanded rapidly over the last 30 years. The old town centre has narrow streets and historic buildings, while the outskirts have new housing estates, a business park and a large supermarket. Greenfield sites around the town are under pressure for development.
城市地区因多种原因而扩展，包括人口增长、人口迁移和经济机会。设想一个名叫“韦尔登”的集镇，在过去30年间迅速扩张。老城区中心街道狭窄，历史建筑林立，而郊区则出现了新的住宅小区、一个商业园区和一个大型超市。城镇周边的绿地正面临开发压力。
Your task is to act as a planner and decide how to manage future growth. The table below shows the advantages and disadvantages of two possible locations for 500 new homes.
你的任务是扮演一位规划师，决定如何管理未来的增长。下表显示了建造500套新住房的两个可能地点的优缺点。
| Site A: Greenfield (farmland NW of town) | Site B: Brownfield (former factory SE of centre) |
| Cheap to build, no demolition needed | Already has roads and electricity connections |
| Would destroy 30 hectares of productive farmland | Land is polluted and needs expensive clean‑up |
| Far from schools and shops; increases car use | Close to existing services, good for walking and cycling |
| Habitats for skylarks and field mice lost | No significant wildlife value but could be turned into green space |
7. Exercise: Analysing Land Use in an Urban Area | 练习：分析城区土地利用
Using the information for Weldon, write a recommendation to the town council. You should state which site you recommend and give at least three reasons, mentioning both human and physical geography. Then, explain one drawback of your chosen site and suggest how it might be overcome. This mirrors the structured decision‑making exercises common in WJEC papers.
利用韦尔登的资料，向镇议会写一份推荐书。要说明你推荐哪个地点，并给出至少三条理由，提及人文地理和自然地理两个方面。然后，解释你所选地点的一个缺点，并提出可能的克服方法。这与WJEC试卷中常见的结构化决策练习是一致的。
To deepen the analysis, draw a simple land‑use map for the brownfield site. Mark the former factory, surrounding residential areas, a nearby river and the proposed housing. Add a key. This helps you appreciate why planners favour brownfield regeneration – it recycles land, reduces pressure on the countryside and creates more sustainable communities.
为了加深分析，为棕地位置绘制一幅简单的土地利用图。标注出旧工厂、周围的居住区、附近的一条河流以及拟建住房。添加图例。这有助于你理解为什么规划者偏爱棕地再开发——它使土地得到循环利用，减轻了给乡村带来的压力，并创造了更可持续的社区。
8. Case Study 4: Weather and Climate – Comparing Two Locations | 案例4：天气与气候——比较两个地点
Weather and climate data allow us to recognise patterns and understand why different places have different conditions. In the UK, western areas tend to be milder and wetter because of the prevailing winds from the Atlantic, while eastern areas are drier and have a greater temperature range. Compare the climate data for two UK locations: Cardiff (west) and Norwich (east).
天气与气候数据使我们能够识别出模式，并理解为什么不同地方有着不同的气候状况。在英国，西部地区因受来自大西洋的盛行风影响，往往较为温和湿润；而东部地区则较为干燥，气温年较差更大。请比较英国两个地点的气候数据：加的夫（西部）和诺里奇（东部）。
| Month | Cardiff T (°C) | Cardiff P (mm) | Norwich T (°C) | Norwich P (mm) |
| Jan | 5 | 120 | 4 | 50 |
| Feb | 5 | 90 | 4 | 38 |
| Mar | 7 | 80 | 7 | 42 |
| Apr | 9 | 70 | 9 | 40 |
| May | 12 | 70 | 13 | 44 |
| Jun | 15 | 65 | 16 | 50 |
| Jul | 17 | 70 | 18 | 55 |
| Aug | 17 | 85 | 18 | 58 |
| Sep | 14 | 95 | 15 | 50 |
| Oct | 11 | 115 | 11 | 62 |
| Nov | 7 | 115 | 7 | 60 |
| Dec | 5 | 125 | 4 | 55 |
9. Exercise: Drawing and Interpreting Climate Graphs | 练习：绘制与解读气候图
Climate graphs combine a line temperature plot with a precipitation bar chart. Using the data table, draw two climate graphs on the same set of axes or on two sheets of graph paper. Use a red line for Cardiff temperature and a blue line for Norwich temperature; use blue bars for rainfall. Then, calculate the annual temperature range for each location and the total annual precipitation.
气候图将温度折线图与降水量柱状图结合在一起。利用数据表，在同一组坐标轴上或两张坐标纸上分别绘制两地的气候图。用红色折线表示加的夫的温度，用蓝色折线表示诺里奇的温度；降水量柱状图则统一用蓝色。然后，计算每个地点的年温差和年总降水量。
After completing your graphs, answer the following: Why does Cardiff receive much more rainfall in autumn and winter? Why is the temperature range slightly larger in Norwich? Explain using geographical terms such as 'prevailing wind', 'distance from the sea' and 'continentality'. These are the building blocks of climate explanations you will need later at GCSE.
完成图表后，回答下列问题：为什么加的夫在秋季和冬季的降水量要大得多？为什么诺里奇的年温差略大一些？请使用“盛行风”、“距海远近”和“大陆度”等地理术语进行解释。这些是你在GCSE阶段需要掌握的气候解释的基本要素。
10. Case Study 5: Ecosystems and Human Impact | 案例5：生态系统与人类影响
A small deciduous woodland near a town has been partially cleared to make way for a housing development. The wood provided habitats for foxes, owls, bluebells and a pond with frogs. Local residents are concerned about the loss of biodiversity. However, the developer argues that the remaining area can be improved with bird boxes, a wildflower meadow and a boardwalk to make the wood more accessible for education.
城镇附近的一片小型落叶林已被部分砍伐，用于建造住宅区。这片林地为狐狸、猫头鹰、蓝铃花以及一个栖息着青蛙的池塘提供了栖息地。当地居民对生物多样性的丧失表示担忧。然而，开发商辩称，剩余区域可以通过安装鸟巢箱、营造野花草甸和铺设木板路来加以改善，使这片林地更适合开展教育活动。
Your task is to assess the environmental change. First, list the positive and negative impacts of the development. Then, decide whether the developer's proposals are genuine conservation or just 'greenwashing' – actions that sound environmentally friendly but do little real good. Use the following criteria to judge: does the plan increase species numbers? Does it protect the pond? Does it connect to a wider ecological network?
你的任务是对这一环境变化进行评估。首先，列出开发的正面和负面影响。然后，判断开发商的提案是真正的保护措施，还是仅仅是“漂绿”——即听起来环保但几乎没有实际好处的行为。根据以下标准进行判断：该计划是否增加了物种数量？是否保护了池塘？是否连接到了更广泛的生态网络？
11. Exercise: Suggesting Sustainable Solutions | 练习：提出可持续解决方案
Based on the ecosystem case study, design your own management plan for the remaining woodland. You must include at least three specific measures – for example, a buffer zone of native shrubs around the pond, restrictions on dog walking during nesting season, or a small outdoor classroom. For each measure, explain why it would help maintain biodiversity. This moves you beyond simple description into evaluation, which earns higher marks.
基于这一生态系统案例研究，为剩余林地设计一份你自己的管理计划。其中必须包含至少三项具体措施——例如，在池塘周围设立一条由本地灌木构成的缓冲带、在鸟类筑巢季节限制遛狗，或者建立一个户外小教室。对每项措施，都要解释为什么它有助于维持生物多样性。这使你从简单的描述提升到了评价层面，从而获得更高的分数。
Then, write a short letter to the town council summarising your plan. Use persuasive language: 'The woodland is not just a collection of trees, but a living network. Without careful stewardship, the unique character of our local environment will be lost.' This exercise helps you practise the communication skills that are part of the WJEC fieldwork enquiry.
然后，写一封给镇议会的短信，概述你的计划。使用有说服力的语言：“这片林地不只是一片树木，而是一个活生生的网络。如果缺乏精心的管理，我们当地环境的独特风貌将不复存在。”这一练习帮助你锻炼沟通技巧，而这正是WJEC实地调查探究的一部分。
12. Conclusion: Building Case Study Skills for GCSE | 结论：为GCSE培养案例研究技能
Working through these practical exercises has given you a toolkit that stretches far beyond Year 7. You have practised interpreting maps and graphs, comparing options, making decisions and justifying them with evidence – exactly the skills that will be examined at GCSE. Remember that the best case study answers are not just lists of facts; they tell a geographical story, connecting physical processes with human decisions.
通过这些实践练习，你获得了一套远超七年级水平的技能工具箱。你练习了解读地图和图表、比较选项、做出决策并用证据加以论证——这些正是GCSE考试中要考查的技能。请记住，最好的案例研究答案不只是一堆事实的罗列；它们讲述的是一个地理故事，将自然过程与人类决策联系起来。
Keep a case study file where you store key facts, sketch maps and summary tables like those in this article. Regularly test yourself by redrawing diagrams from memory and by explaining each case to someone else. Geography becomes much more memorable when you can picture the real places and people behind the textbooks. Good luck, and enjoy exploring the world through case studies!
保留一个案例研究文件夹，用来存储关键事实、示意图和类似本文中的总结表格。定期进行自我测试，比如凭记忆重绘示意图，以及向别人解释每个案例。当你能够想象出课本背后真实的地点和人物时，地理就会变得容易记忆得多。祝你好运，在通过案例研究探索世界的过程中获得乐趣！
