2. The Drainage Basin and River Processes | 流域与河流过程
A drainage basin is the area of land drained by a river and its tributaries. The boundary is called the watershed. Inputs include precipitation; outputs include evaporation and river discharge. Stores and flows move water through the system.
流域是指一条河流及其支流所排水的区域，其边界称为分水岭。输入包括降水；输出包括蒸发和河流流量。储水和径流使水在系统中流动。
Hydraulic action: The sheer force of water breaks rock particles away from the bed and banks.
水力作用：水流的冲击力将岩石颗粒从河床和河岸剥离。
Abrasion: Sand and pebbles carried by the river scrape against the channel, wearing it away like sandpaper.
磨蚀作用：河流携带的沙石刮擦河道，像砂纸一样磨损它。
Attrition: Rocks carried by the river collide and break into smaller, smoother pieces.
磨损作用（颗粒碰撞）：河流搬运的岩石互相碰撞，破碎成更小、更光滑的颗粒。
Solution: Soluble minerals are dissolved by slightly acidic river water.
溶蚀作用：微酸性河水溶解可溶性矿物。
Transportation processes include traction, saltation, suspension and solution. Deposition occurs when the river loses energy, typically when velocity drops on the inside of a meander or at the mouth.
搬运过程包括推移、跃移、悬移和溶解质搬运。当河流能量降低时发生沉积，通常出现在曲流内侧或河口流速下降处。
3. River Landforms | 河流地貌
V-shaped valleys and interlocking spurs form in the upper course where vertical erosion dominates. Waterfalls occur where a band of hard rock lies over softer rock; the soft rock is eroded more quickly, creating a plunge pool and eventually a gorge.
上游以垂直侵蚀为主，形成V形谷和交错山嘴。瀑布出现在硬岩覆盖软岩的地方；软岩侵蚀更快，形成潭穴并最终造就峡谷。
Meanders are bends in the river’s middle and lower courses. The fastest flow swings to the outside, eroding a river cliff, while slower flow on the inside deposits sediment forming a slip-off slope. Oxbow lakes are cut off when two outer banks of a meander meet.
曲流出现在中游和下游河道。最快的水流冲向外侧，侵蚀形成河崖；内侧流速较慢，泥沙沉积形成滑走坡。当曲流的两个外岸相遇，牛轭湖便被截断形成。
Floodplains and levees build up during floods. Levees are raised banks of coarser sediment deposited right next to the channel. Deltas form at the river mouth when sediment supply exceeds the rate of removal by tides and currents.
泛滥平原和自然堤在洪水期堆积而成。自然堤是河道两侧沉积的较粗沉积物所形成的高地。当河流在入海口沉积物供给超过潮汐和海流的搬运能力时，形成三角洲。
4. Coastal Processes | 海岸过程
Waves are created by wind. Constructive waves have a strong swash and weak backwash, building up beaches. Destructive waves have a weak swash and strong backwash, removing beach material.
波浪由风力生成。建设性浪具有强冲洗流和弱回流，可堆积海滩。破坏性浪冲洗流弱而回冲强，带走海滩物质。
Coastal erosion processes parallel river erosion: hydraulic action, abrasion, attrition and solution. Additionally, wave pounding and corrosion (salt weathering) are important at the coast.
海岸侵蚀过程与河流类似：水力作用、磨蚀、磨损和溶蚀。此外，波浪冲击和盐风化（盐类结晶）在海岸也很重要。
Longshore drift moves sediment along the shore. Waves approach at an angle, swash carries material up the beach at that angle, and backwash returns it straight down the slope, creating a zigzag movement.
沿岸漂移将沉积物沿海岸搬运。波浪以一定角度接近，冲洗流将物质以该角度带上滩面，回流则垂直坡面流回，形成之字形运动。
Mass movement includes slumping and rockfalls, often triggered by heavy rain or undercutting of cliffs.
块体运动包括滑坡和岩崩，常由暴雨或海崖底部掏蚀引发。
5. Coastal Landforms and Management | 海岸地貌与管理
Erosional landforms: headlands and bays form where alternating hard and soft rock bands meet the coast. Soft rock erodes more quickly to create a bay; hard rock persists as a headland. Caves, arches, stacks and stumps sequence develops on headlands through hydraulic action and abrasion.
侵蚀地貌：海岬与海湾在软硬岩交替的海岸形成。软岩侵蚀更快形成海湾；硬岩保留为海岬。海蚀洞、海蚀拱、海蚀柱和海蚀残柱序列通过水力作用和磨蚀在海岬上发育。
Depositional landforms include beaches, spits, bars and tombolos. A spit is a long ridge of sand or shingle extending from the shore, often with a curved end where wave refraction occurs. Bars join two headlands, and tombolos connect an island to the mainland.
沉积地貌包括海滩、沙嘴、沙坝和连岛坝。沙嘴是从海岸延伸出的长脊状沙或砾石，末端常因波浪折射而弯曲。沙坝连接两个海岬，连岛坝将岛屿与大陆相连。
Coastal management uses hard engineering (sea walls, groynes, rock armour) and soft engineering (beach nourishment, dune stabilisation). Managed retreat allows controlled flooding of low-value land to create natural flood defences.
海岸管理采用硬工程（海堤、丁坝、消波块）和软工程（海滩补沙、沙丘固定）。有管理撤退策略允许低价值土地有计划被淹没，形成天然防洪带。
6. Weather and Climate Systems | 天气与气候系统
The difference between weather and climate is timescale. Weather is the day-to-day state of the atmosphere; climate is the average conditions over 30 years. The UK’s climate is temperate maritime, influenced by latitude, prevailing winds, ocean currents and altitude.
天气与气候的区别在于时间尺度。天气是大气的日常状态；气候是30年的平均状况。英国属温带海洋性气候，受纬度、盛行风、洋流和海拔的综合影响。
Air masses affecting the UK are polar maritime, polar continental, tropical maritime and tropical continental. Each brings distinct temperature and humidity conditions. The meeting of contrasting air masses at fronts produces precipitation.
影响英国的气团有极地海洋气团、极地大陆气团、热带海洋气团和热带大陆气团。各气团带来不同的温度和湿度。不同气团在锋面交汇时产生降水。
Convectional, relief and frontal rainfall are the three main types. Convectional rainfall occurs when the ground heats up, causing air to rise and cool. Relief rainfall happens when moist air is forced to rise over hills. Frontal rainfall occurs along fronts where warm air rises over colder air.
对流雨、地形雨和锋面雨是三种主要类型。对流雨因地表受热，空气上升冷却而产生。地形雨是湿润空气遇山地抬升造成。锋面雨沿锋面发生，暖空气上升越过冷空气。
7. Ecosystems: Structure and Function | 生态系统：结构与功能
An ecosystem is a community of living organisms interacting with each other and their non-living environment. Components include producers, consumers, decomposers, and abiotic factors such as soil, climate and water.
生态系统是生物群落与彼此及其非生物环境相互作用的整体。包括生产者、消费者、分解者，以及土壤、气候和水等非生物因素。
Food chains and food webs show energy flow. Energy is lost at each trophic level, limiting the length of food chains. Nutrient cycling involves the movement of nutrients between the biomass, litter and soil stores.
食物链和食物网显示能量流动。每一营养级能量都有损失，限制了食物链长度。养分循环涉及营养物质在生物量、枯枝落叶和土壤储库间的转移。
A case study of a small-scale ecosystem, such as a pond or woodland, is often required. You should understand the inputs, outputs, stores and flows, and how changes such as drought or human interference affect the balance.
通常需要一个如池塘或林地的小尺度生态系统案例研究。你需要理解输入、输出、储库和流动，以及干旱或人为干扰如何影响生态平衡。
8. Population and Migration | 人口与迁移
The Demographic Transition Model (DTM) describes population change over time in five stages, from high birth and death rates to low rates. Birth rate, death rate and natural increase are influenced by education, healthcare, economic development and policies.
人口转变模型描述人口随时间变化的五个阶段，从高出生率、高死亡率过渡到低水平。出生率、死亡率和自然增长受教育、医疗、经济发展和政策的共同影响。
Population pyramids show the age and sex structure of a country. A wide base indicates high birth rate; a narrowing top shows low life expectancy. Push and pull factors drive migration: push factors include unemployment, conflict and natural disasters; pull factors include job opportunities, safety and better services.
人口金字塔显示国家的年龄和性别结构。底部宽大表示高出生率；顶部窄小反映低预期寿命。推拉因素驱动迁移：推力因素包括失业、冲突和自然灾害；拉力因素包括工作机会、安全和更好的服务。
Migration can be internal (rural to urban) or international. Impacts on source and host regions are social, economic and environmental.
迁移可以是国内（乡村到城市）或国际的。对来源地和接收地的影响涉及社会、经济和环境。
9. Urbanisation and Settlement | 城市化与聚落
Urbanisation is the increasing proportion of people living in towns and cities. It is most rapid in emerging and developing countries. The causes include rural-urban migration and natural population growth.
城市化是城镇人口比例不断上升的过程，在新兴和发展中国家最为迅速。原因包括城乡迁移和城市人口自然增长。
Settlement hierarchy and functions follow a rank-size order: from isolated dwellings to conurbations. Central place theory explains the spacing and size of settlements based on the services they provide. High-order services have a high threshold population and range.
聚落等级与功能遵循规模序列：从独立住房到城市群。中心地理论根据提供的服务解释聚落的间距和规模。高级别服务具有较高的门槛人口和吸引范围。
Land use models such as the Burgess (concentric) and Hoyt (sector) models describe urban structure. Modern cities often have a CBD, industrial zones, and varied residential areas. Urban challenges include traffic congestion, housing shortages and brownfield redevelopment.
城市土地利用模型如伯吉斯同心圆模型和霍伊特扇形模型描述城市结构。现代城市通常有CBD、工业区和多样化的住宅区。城市挑战包括交通拥堵、住房短缺和棕地再开发。
10. Economic Activity and Development | 经济活动与发展
Economic sectors include primary, secondary, tertiary and quaternary. As countries develop, employment shifts from primary to tertiary and quaternary sectors. The Clark-Fisher model illustrates this change.
经济部门分为第一产业、第二产业、第三产业和第四产业。随着国家发展，就业从第一产业向第三和第四产业转移。克拉克-费希尔模型展示了这一变化。
Development indicators include GNI per capita, literacy rate, life expectancy and HDI. The development gap can be reduced through aid, fair trade, debt relief and investment. A case study of a transnational corporation (TNC) shows how globalisation affects host and source countries.
发展指标包括人均GNI、识字率、预期寿命和人类发展指数。可通过援助、公平贸易、债务减免和投资缩小发展差距。跨国公司的案例研究展示全球化如何影响投资地和母国。
11. Fieldwork and Geographical Skills | 实地考察与地理技能
CCEA Unit 3 requires you to carry out fieldwork and write up a report. You must formulate a hypothesis or enquiry question, collect primary and secondary data, and present it using maps, graphs and charts. Risk assessment is essential before fieldwork.
CCEA Unit 3 要求你开展实地考察并撰写报告。你必须提出假设或调查问题，收集一手和二手数据，并使用地图、图表呈现。实地考察前的风险评估至关重要。
Data collection methods include questionnaires, environmental quality surveys, river velocity and beach profile measurements. Sampling techniques (random, systematic, stratified) ensure representative results. Data presentation may involve bar charts, scatter graphs, field sketches and cross-sections.
数据收集方法包括问卷、环境质量调查、河流流速测量和海滩剖面测量。采样技术（随机、系统、分层）确保结果具有代表性。数据呈现可使用柱状图、散点图、野外速写和剖面图。
Analysis involves identifying trends, anomalies and relationships. Draw conclusions linked to geographical theory, and evaluate the reliability and limitations of your methods.
分析包括识别趋势、异常和关联。得出与地理理论相关的结论，并评价所用方法的可靠性和局限性。
12. Exam Strategies and Tips | 考试策略与技巧
In CCEA Geography, command words are crucial. ‘Describe’ requires stating what you see; ‘explain’ requires giving reasons; ‘evaluate’ means weighing up pros and cons and making a judgement. Always read the question carefully to match the command word.
在CCEA地理考试中，指令词至关重要。”描述”要求说明你所见；”解释”要求给出理由；”评估”意味着权衡利弊并作出判断。务必仔细审题以匹配指令词。
Use the PEEL structure for longer answers: Point, Evidence, Explanation, Link. Apply case studies with specific place detail (names, numbers, dates) to access higher marks. Time management is key; allocate time in proportion to the marks available.
长答案使用PEEL结构：观点、证据、解释、联系。运用案例研究，使用具体地名、数据和日期以获取高分。时间管理是关键；按照分值比例分配答题时间。
Practise sketch maps, diagrams and graph interpretation. Geography is visual; annotating diagrams effectively can strengthen your explanations. Finally, revise actively by testing yourself on processes, landforms and case study facts.
多练习示意图、图表和图形解读。地理课注重图像；有效注释示意图能加强你的解释。最后，通过自测过程、地貌和案例事实进行主动复习。
