1. Hydrological Cycle and Drainage Basins | 水循环与流域

Question: Describe the main stores and flows within the hydrological cycle. (5 marks)

问题：描述水循环中的主要储存库与流动过程。（5分）

The hydrological cycle includes stores such as oceans, ice caps, groundwater, lakes and the atmosphere. Flows (or transfers) move water between these stores. Key flows are evaporation (water changing to vapour and rising from oceans and land), transpiration (release of water vapour from plants), condensation (vapour turning into liquid forming clouds), precipitation (rain, snow or hail falling to the ground), surface runoff (water flowing over the land surface), infiltration (water soaking into the soil) and throughflow (water moving through the soil layer).

水循环包含的储存库有海洋、冰盖、地下水、湖泊和大气。流动（或转移）过程使水在这些储存库之间移动。主要流动包括蒸发（水变为水蒸气从海洋和陆地上升）、蒸腾（植物释放水蒸气）、凝结（水蒸气变为液态形成云）、降水（雨、雪或冰雹落到地面）、地表径流（水在地表流动）、下渗（水渗入土壤）和土壤内水流（水在土壤层内移动）。

For full marks, clearly distinguish between stores and flows and provide named examples of each. In WJEC mark schemes, precise terminology is essential — using ‘infiltration’ rather than ‘soaking’ and naming at least one store such as ‘glaciers’ will secure top-band marks.

要获得满分，必须清楚区分储存库与流动，并对每个术语举例说明。在 WJEC 评分方案中，准确使用术语至关重要——使用“下渗”而非“浸湿”，并至少说出一个储存库如“冰川”，才能获得高分段分数。

2. River Landforms: Waterfalls and Gorges | 河流地貌：瀑布与峡谷

Question: Explain the formation of a waterfall and the resulting gorge. You may use a labelled diagram in your answer. (6 marks)

问题：解释瀑布及其造成的峡谷的形成过程。你可以在答案中使用带注释的示意图。（6分）

A waterfall forms where a band of hard rock (e.g. granite) lies over a layer of soft rock (e.g. shale). The river erodes the soft rock more rapidly through hydraulic action and abrasion, creating an overhang of hard rock. The plunge pool at the base is deepened by the force of falling water and the swirling action of rock fragments. Over time, the overhang collapses due to gravity, causing the waterfall to retreat upstream. This continued retreat leaves behind a steep-sided gorge downstream of the waterfall’s new position.

瀑布形成于硬岩层（如花岗岩）覆盖在软岩层（如页岩）之上的地方。河流通过水力作用和磨蚀更快地侵蚀软岩，形成硬岩悬垂。瀑布底部的跌水潭因水流落差和岩石碎屑的涡流作用而不断加深。随着时间推移，悬垂部分因重力而坍塌，导致瀑布向上游后退。这种持续后退在瀑布新位置的下游留下陡峭的峡谷。

To maximise marks, sequence the explanation clearly: differential erosion → undercutting → overhang collapse → retreat → gorge. Including the named processes ‘hydraulic action’ and ‘abrasion’ and referring to rock types will demonstrate high-level knowledge.

要拿到高分，必须清晰排序：差异侵蚀 → 底切 → 悬垂坍塌 → 后退 → 峡谷。如果提到“水力作用”和“磨蚀”等过程名称，并提及岩石类型，将展示出高水平的知识。

3. Coastal Erosion Landforms: Headlands and Bays | 海岸侵蚀地貌：岬角与海湾

Question: Using a case study from the UK, explain how headlands and bays are formed. (6 marks)

问题：以英国的一个案例研究为例，解释岬角和海湾是如何形成的。（6分）

Headlands and bays form along coastlines with alternating bands of hard and soft rock at discordant angles to the sea. Soft rock (e.g. clay) erodes quickly by hydraulic action and abrasion, forming a bay. Hard rock (e.g. chalk) resists erosion and juts out as a headland. At the Dorset coastline, Swanage Bay is a fine example. The soft Wealden clay was eroded rapidly to create the bay, while the harder Purbeck limestone and chalk form the headlands of Peveril Point and Ballard Down. Bays provide sheltered water for beaches, while headlands are exposed to wave refraction, concentrating energy and leading to further erosion features like caves and stacks.

岬角和海湾形成于海岸线上，硬软岩层交替出现并与之以不协调的角度相交。软岩（如黏土）被水力作用和磨蚀快速侵蚀，形成海湾。硬岩（如白垩）抵抗侵蚀并突出成为岬角。在多塞特海岸，斯沃纳奇湾就是一个很好的例子。柔软的韦尔德黏土被迅速侵蚀形成海湾，而较硬的波贝克石灰岩和白垩则形成了佩弗里尔角和巴拉德角的岬角。海湾为海滩提供了庇护水域，而岬角暴露在波浪折射下，能量集中，导致洞穴、海栈等进一步侵蚀地貌的出现。

When using a case study, always name specific locations and rock types. The WJEC examiner expects precise detail — stating ‘Swanage Bay, Dorset’ and identifying ‘Wealden clay’ demonstrates case study application and geographical knowledge, which is a key discriminator for high marks.

在使用案例研究时，务必说出具体地点和岩石类型。WJEC 考官期望准确的细节——说出“多塞特的斯沃纳奇湾”并指出“韦尔德黏土”，能展示案例应用和地理知识，这是区分高分的关键。

4. Coastal Management Strategies | 海岸管理策略

Question: Evaluate the effectiveness of hard engineering in protecting coastlines from erosion. Use a named UK example. (8 marks)

问题：评价硬工程在保护海岸线免受侵蚀方面的有效性。使用一个英国典型案例。（8分）

Hard engineering involves rigid structures such as sea walls, groynes and rock armour. At Hornsea on the Holderness Coast, a concrete sea wall with a promenade was built to reflect wave energy. Groynes trap sediment and have maintained a wider beach, which absorbs wave power. However, these interventions are expensive to install and maintain. Sea walls can cause wave reflection, increasing scour at their base. Groynes starve down-drift beaches, leading to accelerated erosion further south, such as at Mappleton. While hard engineering provides immediate, visible protection, it often transfers the erosion problem elsewhere and may not be sustainable long-term, especially with rising sea levels.

硬工程涉及海堤、丁坝和抛石等刚性构筑物。在霍尔德内斯海岸的霍恩西，建造了一道带步行道的混凝土海堤用以反射波浪能。丁坝截留沉积物，维持了较宽的海滩，从而吸收波浪能量。然而，这些干预措施的安装和维护成本高昂。海堤可能引起波浪反射，加剧堤脚的冲刷。丁坝使下游海滩缺少泥沙，导致更南端地区（如马普尔顿）的加速侵蚀。虽然硬工程能提供即时、可见的保护，但往往将侵蚀问题转移到别处，并且可能无法长期持续，尤其是在海平面上升的情况下。

An evaluate question requires both strengths and weaknesses. Reference to a named location with specific details (Holderness Coast, Hornsea and Mappleton) is vital. For top marks, you must also weigh up sustainability and mention the concept of sediment cells being interrupted. This shows evaluative geographical thinking.

评价类题目要求同时阐述优点和缺点。提及一个有名有姓且有具体细节的地点（霍尔德内斯海岸，霍恩西和马普尔顿）至关重要。若要得到最高分，还必须权衡可持续性，并提到沉积物链被干扰的概念，这体现了评价性的地理思维。

5. Weather and Climate: Anticyclones | 天气与气候：反气旋

Question: Describe the weather conditions associated with a winter anticyclone in the British Isles and explain why these conditions occur. (5 marks)

问题：描述不列颠群岛冬季反气旋带来的天气状况，并解释这些状况发生的原因。（5分）

In a winter anticyclone, air pressure is high, skies are often clear and winds are light or calm. Temperatures drop rapidly at night due to terrestrial radiation, leading to frost and, in still conditions, radiation fog. Days are cold but sunny. Conditions persist for several days because the high-pressure system is slow-moving. The anticyclone brings dry weather because sinking air warms adiabatically, suppressing cloud formation. At night, long-wave radiation escapes efficiently without cloud cover, causing surface cooling. These conditions can result in icy roads and poor visibility from fog, affecting transport.

在冬季反气旋中，气压高，天空通常晴朗，风很轻或静稳。夜间由于地面辐射，温度迅速下降，导致霜冻，在静稳条件下还会形成辐射雾。白天寒冷但晴朗。由于高压系统移动缓慢，这种天气状况会持续多日。反气旋带来干燥天气是因为下沉空气绝热增温，抑制了云的形成。夜间，由于无云遮挡，长波辐射有效散逸，导致地表冷却。这些状况可能导致道路结冰和雾霾造成能见度降低，影响交通。

Use key terminology such as ‘subsidence’, ‘radiation cooling’, ‘clear skies’ and ‘long-wave radiation’. WJEC mark schemes award marks for explaining cause and effect, so linking sinking air to lack of cloud and then to frost formation shows sequential reasoning.

使用关键术语，如“下沉”、“辐射冷却”、“晴朗天空”和“长波辐射”。WJEC 的评分方案奖励对因果关系的解释，因此将下沉空气与无云联系起来，再到霜冻的形成，可以展示顺序推理能力。

6. Population Dynamics: Demographic Transition Model | 人口动态：人口转变模型

Question: Explain how birth rates and death rates change through the stages of the Demographic Transition Model. (6 marks)

问题：解释人口转变模型各阶段中出生率和死亡率的变化。（6分）

Stage 1: Both birth rate and death rate are high and fluctuate, resulting in a stable but low total population. Stage 2: Death rate falls sharply due to improved healthcare, sanitation and diet, while birth rate remains high, leading to rapid population increase. Stage 3: Birth rate begins to decline as a result of economic changes, women’s education, family planning and a move towards smaller families. Death rate continues to fall but more slowly. Stage 4: Both birth rate and death rate are low, sometimes with the death rate slightly exceeding the birth rate, leading to a slowly aging population. Stage 5 (proposed): Birth rate falls below death rate, causing population decline unless compensated by immigration.

阶段1：出生率和死亡率都很高且波动不定，导致总人口规模稳定但较低。阶段2：由于医疗、卫生和饮食条件的改善，死亡率急剧下降，而出生率仍保持高位，导致人口迅速增长。阶段3：由于经济变化、女性教育、计划生育和向小家庭趋势的转变，出生率开始下降。死亡率继续下降但速度放缓。阶段4：出生率和死亡率都处于低水平，有时死亡率略高于出生率，导致人口缓慢老化。阶段5（建议阶段）：出生率降至死亡率以下，若不靠移民弥补，人口将出现负增长。

For WJEC, it is important to explain the reasons behind the changes, not just to describe them. For example, mention ‘improved sanitation reduces infectious diseases’ for the death rate drop in Stage 2 and ‘women’s career opportunities’ for the birth rate decline in Stage 3.

对 WJEC 来说，重要的是解释变化背后的原因，而不仅仅是描述。例如，在阶段2的死亡率下降中提及“卫生改善减少了传染病”，在阶段3的出生率下降中提及“女性的职业机会”。

7. Challenges of Urbanisation in LICs | 低收入国家城市化的挑战

Question: For a named city in a Low Income Country (LIC) or Newly Emerging Economy (NEE), explain the challenges created by rapid urbanisation. (6 marks)

问题：以一个低收入国家或新兴经济体的一个城市为例，解释快速城市化带来的挑战。（6分）

Mumbai, India, experiences intense challenges due to rapid rural-to-urban migration and natural increase. Housing shortages force many to live in informal settlements (slums) like Dharavi, where dwellings lack secure tenure and basic services. Overburdened infrastructure results in traffic congestion, unreliable water supply and frequent power cuts. Waste disposal is inadequate, leading to environmental pollution and health risks such as diarrhoeal diseases. Unemployment and underemployment are widespread because the formal economy cannot absorb the rapidly growing workforce. These problems are compounded by limited municipal funding.

印度孟买因快速的城乡迁移和自然增长而面临严峻挑战。住房短缺迫使许多人生活在如达拉维这样的非正规住区（贫民窟），那里的住所缺乏稳定的居住权和完善的基本服务。不堪重负的基础设施导致交通拥堵、供水不可靠和频繁停电。废物处理能力不足，引发环境污染和健康风险，如腹泻类疾病。由于正规经济无法吸纳迅速增长的劳动力，失业和就业不足现象普遍存在。这些问题因市政资金有限而更加严重。

Specific place detail is essential. Refer to ‘Dharavi’, ‘Mumbai population growth’ and precise problems such as ‘one toilet per 500 residents’. The evaluative touch — commenting on the cycle of deprivation — will push a response into the highest tier.

具体的地点细节至关重要。提及“达拉维”、“孟买人口增长”以及诸如“每500名居民共用一个厕所”等确切问题。评价性的笔触——评论贫困循环——能将答案推至最高档次。

8. Measuring Development: Indicators and Contrasts | 衡量发展：指标与对比

Question: Discuss the limitations of using a single economic indicator, such as GNI per capita, to measure a country’s level of development. Use examples. (6 marks)

问题：讨论使用单一经济指标（如人均GNI）衡量一国发展水平的局限性。请举例说明。（6分）

GNI per capita (Gross National Income per person) is an average and does not reveal inequalities within a country; a small wealthy elite can mask widespread poverty. It also omits non-monetary aspects of wellbeing such as health, education and personal safety. For instance, Equatorial Guinea has a relatively high GNI per capita due to oil revenues, but life expectancy is low and access to clean water is poor. Conversely, Sri Lanka has a lower GNI per capita than some oil-rich states but achieves high literacy and life expectancy. Development is multidimensional, so composite indices like the Human Development Index (HDI) provide a fuller picture.

人均国民总收入是一个平均值，不能揭示国家内部的不平等；少数富裕精英的存在可能掩盖了普遍的贫困。它还忽略了健康、教育和个人安全等非货币福祉方面。例如，赤道几内亚因石油收入而人均GNI相对较高，但预期寿命低，清洁水供应差。相反，斯里兰卡的人均GNI低于一些石油富国，但识字率和预期寿命都很高。发展是多维度的，因此像人类发展指数这样的综合指标能提供更全面的情况。

For discussion questions, present a balanced analysis. Mention the ‘hidden economy’ or informal sector, which GNI often fails to capture, and contrast countries like Qatar and Cuba to illustrate the gap between income and welfare. Using a range of specific examples shows breadth of knowledge.

对于讨论类题目，要呈现均衡分析。提及“灰色经济”或非正规部门（GNI 常无法统计），并将卡塔尔和古巴这样的国家进行对比，以说明收入与福利之间的差距。使用一系列具体范例能显示知识的广度。

9. OS Map Skills: Four-Figure and Six-Figure Grid References | 地形图技能：四位与六位坐标网读数

Question: Give the six-figure grid reference of the church at point X on the provided Ordnance Survey map extract. (2 marks) Explain how you locate a feature using six-figure grid references. (2 marks)

问题：在提供的地形图截图中，给出 X 点教堂的六位坐标网读数。（2分）解释如何使用六位坐标网读数定位地物。（2分）

To find a six-figure grid reference, first identify the eastings number of the grid square containing the feature (the number along the west edge of that square), then measure tenths eastward within the square. Next, read the northings number along the south edge of the square, then measure tenths northward. For example, if the church lies in square 1234, and is 7 tenths east and 5 tenths north, the reference is 127345. Six-figure references give the location to within 100 m on the ground, whereas four-figure references (e.g. 1234) give only the 1 km square. Accuracy depends on careful estimation using a ruler or a romer.

要获取六位坐标网读数，首先确定包含该地物的网格方格的东距编号（即方格西边的数字），然后测量方格内向东的十分之一。接着，读取方格南边的北距编号，再测量向北的十分之一。例如，如果教堂位于1234方格内，且向东十分之七、向北十分之五，则该读数为127345。六位坐标能在地面上定位到100米以内，而四位坐标（如1234）仅能定位到1公里的方格。精确度取决于使用直尺或坐标量测尺的仔细估算。

Always say ‘along the corridor’ (eastings) first and ‘up the stairs’ (northings) second. In the exam, even if the reference is partly guessed, clearly showing your working and using the correct format will earn method marks.

始终遵循“先走走廊”（东距）再“上楼”（北距）的原则。考试中，即使读数部分靠猜测，但只要清晰展示步骤并使用正确格式，仍能获得方法分。

10. Case Study: Coastal Erosion Management at Holderness | 案例研究：霍尔德内斯的海岸侵蚀管理

Question: For the Holderness Coast, assess the success of managed retreat or ‘do nothing’ approaches compared with hard engineering. (8 marks)

问题：以霍尔德内斯海岸为例，评估有计划的退缩或“不作为”策略相对于硬工程的成功之处。（8分）

The Holderness Coast in East Yorkshire has an average erosion rate of about 2 metres per year. At locations such as Easington, where the gas terminal is at risk, hard engineering like rock armour and sea walls has successfully protected key infrastructure. However, south of Mappleton, the council has adopted a ‘do nothing’ approach for some farmland, allowing the natural process to continue. This is cost-effective and maintains sediment supply to downdrift beaches like Spurn Head, a dynamic spit. On the other hand, managed retreat at sites like Skipsea involves relocating homes and businesses inland, which is socially controversial but environmentally sustainable. Overall, ‘do nothing’ works where land value is low, while hard engineering is justified for high-value assets. The success depends on balancing economic, social and environmental factors.

东约克郡的霍尔德内斯海岸平均侵蚀速率约为每年2米。在天然气终端面临风险的伊辛顿等地，抛石和海堤等硬工程成功保护了关键基础设施。然而，在马普尔顿以南，议会对部分农田采取了“不作为”策略，允许自然过程继续。这种做法成本效益高，并维持了向下游海滩（如斯珀恩角这一活跃沙嘴）输送沉积物。另一方面，在斯基普西等地，有计划的退缩涉及将住宅和企业向内陆迁移，这在社会上存在争议，但在环境上具有可持续性。总体而言，“不作为”适合于土地价值低的地方，而硬工程用于高价值资产是合理的。成功与否取决于对经济、社会和环境因素的平衡。

To achieve the highest marks, integrate specific geographical concepts such as ‘sediment cell’, ‘longshore drift’ and ‘cost-benefit analysis’. Compare at least two contrasting locations along the Holderness Coast and offer a justified conclusion on the future management strategy under climate change.

要获得最高分，需融入“沉积物单元”、“沿岸泥沙流”和“成本效益分析”等具体地理概念。至少对比霍尔德内斯海岸上两个截然不同的地点，并就气候变化下的未来管理策略给出有理有据的结论。
