1. River Landscapes and Processes | 河流景观与过程术语速记
Erosion processes: Hydraulic Action (water force), Abrasion (rocks scrape bed), Attrition (rocks collide) and Solution (acids dissolve). Remember the order with HAAS – from power to chemistry. In the upper course, vertical erosion dominates, creating V-shaped valleys; in the lower course, lateral erosion widens the channel. Think 'vertical to V, lateral to meander'.
侵蚀过程：水力作用（水力冲击）、磨蚀（岩屑刮擦河床）、磨耗（岩屑相互碰撞）和溶蚀（酸类溶解）。用HAAS助记，由物理到化学。上游以垂直侵蚀为主，形成V形谷；下游侧向侵蚀显著，河道变宽。联想“垂直→V形，侧向→蜿蜒”。
Transportation: Traction (boulders roll), Saltation (pebbles bounce), Suspension (silt floats) and Solution (dissolved load). The mnemonic TSSS mirrors the diminishing particle size. A simple image: 'heavy traction on the bed, salty bounce, silt in the water, invisible solution.'
搬运作用：推移（砾石滚动）、跃移（小卵石弹跳）、悬移（泥沙悬浮）和溶解搬运（溶解质）。用TSSS反映粒径递减。记忆画面：“大石块河底移，小石蹦跳似盐跃，泥沙悬在水中游，溶解物质看不见。”
Landforms: Meanders bend with faster flow on the outside (erosion, river cliff) and slower inside (deposition, slip-off slope). When a meander cuts off, it forms an oxbow lake. Floodplains and levees build during repeated floods. Link: 'meaner curve → oxbow loop → cut-off necklace'.
地形：河曲（蛇曲）外侧水流急（侵蚀成凹岸），内侧水流缓（沉积成凸岸）。当河曲被截弯取直，便形成牛轭湖。河漫滩与天然堤经多次洪水堆积而成。联想：“弯曲像项链，折断变牛轭。”
2. Coastal Landscapes and Processes | 海岸景观与过程术语速记
Wave types: Constructive waves (low, long wavelength, strong swash) build beaches; Destructive waves (high, steep, strong backwash) erode. Picture a 'C for calm and construction' and 'D for destructive and dramatic'. Wave energy depends on fetch – the distance wind blows over water.
波浪类型：建设性波浪（低缓、波长长、冲流强）营造海滩；破坏性波浪（高而陡、回流强）侵蚀海岸。联想：'C → calm and build，D → destructive and dramatic'。波能取决于风区长度（fetch）——风吹过水面的距离。
Erosion features: Hydraulic action and abrasion create wave-cut notches → cliff collapse → wave-cut platform. Headlands erode into caves, arches, stacks and stumps. Sequence mnemonic: CHAS (Cave → Headland, Arch, Stack, Stump). Add the story: 'the headland first caves, then arches, then a stack, finally a stump.'
侵蚀地貌：水力作用和磨蚀塑造出海蚀凹槽→悬崖崩塌→海蚀平台。岬角被侵蚀成海蚀洞、海蚀拱、海蚀柱和海蚀残桩。顺序助记：洞→拱→柱→桩。编个故事：'岬角先掏洞，再凿成拱，拱塌成柱，柱磨成桩。'
Deposition landforms: Beaches, spits (longshore drift extends sand across an estuary), and bars (a spit joining two headlands). Longshore drift the zigzag movement of sediment along the coast. Think 'swash comes in angled, backwash goes straight out – zigzag drift'.
沉积地貌：海滩、沙嘴（沿岸漂移使泥沙延伸过河口）和沙坝（沙嘴连接两岬角）。沿岸漂移是泥沙沿海岸的之字形运动。记住'冲流斜着上，回流垂直下——之字漂移'。
3. Weather Hazards and Climate Change | 天气灾害与气候变化术语速记
Global atmospheric circulation: Three cells per hemisphere – Hadley (0°–30°), Ferrel (30°–60°), Polar (60°–90°). The Hadley cell drives tropical rainforests at the equator and deserts at 30°. Mnemonic: 'Hadley heats, Ferrel mixes, Polar pushes'. Low pressure at the equator (rising air) creates rain; high pressure at 30° (sinking air) gives aridity.
全球大气环流：每半球三个环流圈——哈得来环流（0°–30°）、费雷尔环流（30°–60°）、极地环流（60°–90°）。哈得来环流造就赤道雨林和副热带沙漠。助记：'哈得来加热上升，费雷尔交织混合，极地冷重下沉'。赤道低压（气流上升）多雨；30°高压（气流下沉）干旱。
Tropical cyclones: Form over warm oceans (>27°C), with Coriolis effect creating spin. Structure: eye (calm), eyewall (strongest winds), rainbands. Remember 'warm water + spin = cyclogenesis'. Hazards include storm surges, high winds and flooding. Case study: Typhoon Haiyan (2013) – primary and secondary effects.
热带气旋：形成于暖洋面（>27°C），科里奥利力使其旋转。结构：风眼（平静）、眼壁（最强风）、螺旋雨带。记住'暖水 + 旋转 = 气旋生成'。灾害包括风暴潮、狂风和洪水。案例：2013年台风海燕——原生与次生影响。
Climate change evidence: Ice cores (CO₂ trapped), tree rings, sea level rise (eustatic change), shrinking glaciers. Human causes: enhanced greenhouse effect (CO₂, methane). Mitigation vs adaptation: 'mitigate the source, adapt to the impact'.
气候变化证据：冰芯（封存CO₂）、树木年轮、海平面上升（水动型变化）、冰川退缩。人为原因：增强的温室效应（CO₂、甲烷）。缓解与适应：'缓解针对源头，适应应对影响'。
4. Ecosystems and Tropical Rainforests | 生态系统与热带雨林术语速记
Ecosystem components: abiotic (non-living). Producers → consumers (herbivore, carnivore, omnivore) → decomposers – linked in a food web. Nutrient cycling: litter, biomass, soil stores. Remember the Gersmehl model showing stores and flows of nutrients; larger circles in TRF = rapid cycling.
生态系统组成：生物因子与非生物因子。生产者→消费者（草食、肉食、杂食）→分解者——构成食物网。营养循环：枯枝落叶、生物量、土壤储存。记住格斯梅尔模型，热带雨林圆圈大代表快速循环。
Tropical rainforest characteristics: Emergents, canopy, understorey, shrub layer. High biodiversity, leaching, latosols. Climate: hot (25–30°C) and wet (2000 mm/year). Adaptation examples: drip tips, buttress roots, lianas. Link 'tall trees struggle for light; drip-tip leaves shed water fast'.
热带雨林特征：露生层、树冠层、下层林木、灌木层。高生物多样性、淋溶作用、砖红壤。气候：终年高温（25–30°C）多雨（2000 mm/年）。适应性举例：滴水叶尖、板根、藤本植物。联想'高树争光急，叶尖速排雨'。
Deforestation causes & impacts: Subsistence farming, logging, mining, HEP dams. Impacts: soil erosion, biodiversity loss, less CO₂ absorption. Value of TRF: 'lungs of the Earth', medicine, indigenous homes. Sustainable management: selective logging, ecotourism, debt-for-nature swaps.
森林砍伐的成因与影响：自给农业、商业采伐、采矿、水电大坝。影响：水土流失、生物多样性下降、碳汇减少。雨林价值：“地球之肺”、药物、原住民家园。可持续管理：择伐、生态旅游、债务换自然。
5. Urbanisation and City Change | 城市化与城市变迁术语速记
Urbanisation patterns: In HICs, urbanisation occurred early (Industrial Revolution); now counter-urbanisation and re-urbanisation are common. In LICs/NEEs, rapid rural-to-urban migration drives megacity growth. Push–pull factors: remember 'jobs pull, poverty pushes'. Natural increase also adds to urban populations.
城市化模式：高收入国家城市化早（工业革命）；如今逆城市化和再城市化常见。低收入/新兴经济体正经历快速乡城迁移，催生巨型城市。推拉因素：记住'工作拉，贫困推'。自然增长同样扩大城市人口。
Urban models: Burgess concentric ring model (CBD, inner city, inner/outer suburbs). The inner city may experience deindustrialisation and deprivation. Remember 'from CBD outward: old industry, terraced houses, then semis and detached'. Compare with Hoyt's sector model for transport corridors.
城市模型：伯吉斯同心圆模型（CBD、内城、内/外郊区）。内城可能经历去工业化和贫困。记住'从CBD向外：旧工业、排屋，再到半独栋和独栋'。对照霍伊特扇形模型理解交通廊道。
Sustainable cities: Features: green belts, integrated transport, brownfield sites, energy-efficient buildings. Curitiba's BRT, Copenhagen's cycling. Key terms: urban greening, liveability, smart cities. 'Green on the edge, brown inside, move by bus and bike' summarises sustainable design.
可持续城市：特征：绿带、综合交通、棕地开发、节能建筑。库里蒂巴BRT、哥本哈根自行车。关键术语：城市绿化、宜居性、智慧城市。'外围绿带限扩张，内部棕地再开发，公交骑行最优先'概括可持续设计。
6. Global Development Gap | 全球发展差距术语速记
Measures of development: GNI per capita (economic); HDI (health, education, income); literacy rate, life expectancy. Composite indicators are more reliable. Remember 'HDI = 3-in-1 health, education, wealth'. The Brandt Line (1980s) divided rich North and poor South, but it oversimplifies today's picture.
发展指标：人均GNI（经济）；HDI（健康、教育、收入）；识字率、预期寿命。综合指标更可靠。记住'HDI是三位一体：健康、教育和财富'。勃兰特线（1980年代）划分南北，但已过度简化当今格局。
Causes of the gap: Historical colonialism, unfair trade, debt, climate vulnerability, corruption. The cycle of poverty traps LICs: 'low income → low savings → low investment → low productivity'. Physical factors: landlocked countries, disease burdens.
差距的成因：殖民历史、不公平贸易、债务、气候脆弱性、腐败。贫困陷阱循环：'低收入→低储蓄→低投资→低生产率'。自然因素：内陆国、疾病负担。
Closing the gap: Aid (bilateral, multilateral), fair trade, debt relief, intermediate technology, microfinance. Top-down vs bottom-up projects: remember 'top-down big dam, bottom-up village tap'. Case study: a bottom-up water project in Ethiopia.
缩小差距：援助（双边、多边）、公平贸易、债务减免、中间技术、小额信贷。自上而下与自下而上：记住'自上大坝建，自下村水龙头'。案例：埃塞俄比亚的民众水项目。
7. Energy Resource Management | 能源资源管理术语速记
Energy classification: Non-renewable (coal, oil, gas, nuclear) and renewable (solar, wind, hydro, tidal, geothermal, biomass). Remember the renewables as 'SHWTGB' – Solar, Hydro, Wind, Tidal, Geothermal, Biomass. Renewables are often intermittent; energy mix is the share of sources in total supply.
能源分类：不可再生能源（煤、石油、天然气、核能）与可再生能源（太阳能、风能、水电、潮汐、地热、生物质）。记住可再生能源的SHWTGB：太、水、风、潮、地、生。可再生能源常具间歇性；能源结构指各类来源在总供应中的比例。
Energy security: Availability, accessibility, affordability, reliability. 'Four As' – Available, Accessible, Affordable, Acceptable (environment). Diversifying energy mix reduces dependence. The UK's energy security increased with offshore wind and nuclear new build.
能源安全：可得性、可及性、可负担性、可靠性。四个A：Available, Accessible, Affordable, Acceptable。多元化能源结构降低依赖。英国通过海上风电和新建核电站提高了能源安全。
Impacts & sustainability: ng scars. Renewable advantages: low carbon, but habitat loss (HEP dams). Energy conservation vs efficiency – 'use less (conservation) vs use smarter (efficiency)'. E.g. LED bulbs, insulation.
影响与可持续性：化石燃料→温室气体排放和采矿疮疤。可再生能源优势：低碳，但水电大坝引发生境损失。节能与能源效率——'用得更少（节约），还是用得更巧（效率）'，例如LED灯泡、保温层。
8. Fieldwork and Enquiry Skills | 实地考察与调查技能术语速记
Enquiry stages: n → Analysis → Conclusion → Evaluation. The hypothesis must be a testable statement, e.g., 'width increases downstream.' Remember 'Primary = you collect; Secondary = someone else'.
调查阶段：提出问题→假设→数据收集（一手/二手）→数据展示→分析→结论→评估。假设必须是可检验的陈述，如“河道宽度向下游增加”。记住'一手自采，二手他收'。
Sampling strategies: Random (everyone equal chance), Systematic (regular intervals), Stratified (proportional groups). For river width, systematic at every 100 m works well. 'Random for unbiased, systematic for pattern, stratified for groups'.
抽样策略：随机（人人平等概率）、系统（等距间隔）、分层（按比例分组）。测量河宽可用每100米系统抽样。'随机求无偏，系统寻规律，分层保代表'。
Data presentation: Line graphs (continuous data, e.g., river depth), bar charts (categories), scattergraphs (correlation), pie charts (percentages). For a beach profile, use a labelled field sketch or kite diagram. Always include a title, labelled axes, and a key.
数据展示：折线图（连续数据，如水深）、柱状图（类别）、散点图（相关性）、饼图（百分比）。展示海滩剖面可用标注实地速写或风筝图。务必写出标题、标注轴、附上图例。
9. Mapwork and Graphical Skills | 地图与图表技能术语速记
Grid references: 4-figure (e.g., 2437 gives the grid square) and 6-figure (e.g., 245375 gives a point). 'Along the corridor (easting) and up the stairs (northing)'. Relief is shown by contours (close = steep), spot heights, hachures. Remember 'contour crowding = cliff'.
网格坐标：四位数坐标（如2437标示网格方格）与六位数坐标（如245375定位点）。'沿走廊（东向坐标）再上楼（北向坐标）'。等高线（密集=陡坡）、高程点、晕滃线展示地形。记住'等高线密成崖'。
Scale and distance: Represented as ratio (1:25,000) or linear bar. Measure straight-line distance with a ruler, curved distance with string. A compass rose shows magnetic north; orient the map using a compass bearing.
比例尺与距离：用比例（1:25,000）或直线比例尺表示。直尺量直线距离，细绳量曲线距离。罗盘花指示磁北；利用罗盘方位定向地图。
Graphical analysis: Use isolation maps (choropleth, dot), isoline maps (isotherms), and GIS layers. The 'mantra for describing graphs: GEEC – General trend, Example data, Exception, Conclusion'. On an exam question, always quote data.
图型分析：分区密度图（choropleth、点值图）、等值线图（等温线）和GIS图层。'描述图表口诀：总趋势、引数据、找例外、下结论（GEEC）'。答题时务必引用数据。
10. Command Words and Exam Technique | 指令词与考试技巧术语速记
Command words decoded: Identify/Describe – what? (no explanation). Explain – why/how? Use 'because'. Compare – similarities and differences using connectives. Evaluate/Assess – weigh evidence, give a supported judgement. Remember 'Describe = picture, Explain = reason, Evaluate = balanced verdict'. The 8-markers need PEEL paragraphs: Point – Explain – Evidence – Link.
指令词解码：“识别/描述”——是什么？（无需解释）。“解释”——为什么/怎么样？用“因为”。“比较”——异同点，用连接词。“评价/评估”——权衡证据，给出有支撑的判断。记住'描述画画面，解释给理由，评价作权衡'。8分题需用PEEL段落：观点—解释—证据—回链。
Case study structure: Name and locate first. Always include specific figures and place names. For a tropical cyclone, quote wind speed, number of deaths, GDP loss. Use '3Ps: Place, Process, People' to structure answers.
案例研究框架：先写出名称和位置。务必使用具体数据与地名。如热带气旋案例，引风速、死亡人数、GDP损失。利用'3P：地点Place、过程Process、人群People'组织答案。
Time management: 1 mark per minute roughly. Start with the 8-markers to secure depth. Underline command words and qualifiers (e.g., 'mainly', 'compare'). In the final minute, scan for missed parts. 'Plan 8-markers: 2 min plan, 6 min write.'
时间管理：大致1分值对应1分钟。先从8分题入手，确保深度。划出指令词与限定词（如“主要”、“比较”）。最后一分钟速查遗漏。'8分题：2分钟计划，6分钟作答。'
