1. Population Dynamics | 人口动态
Birth rate is the number of live births per 1,000 people per year. Think of it as the 'B' in the balancing act of population: births add to the total. When you see a high birth rate, imagine a large baby boom at the top of the population pyramid.
出生率 指每年每千人口中的活产婴儿数。可以把它想象成人口天平上代表 '出生' 的一端：出生会使总人口增加。当你看到高出生率时，不妨想象人口金字塔顶部有一波巨大的婴儿潮。
Death rate is the number of deaths per 1,000 people per year. Paired with birth rate, it determines natural increase - DR. Remember that even a small difference over time can lead to rapid population growth.
死亡率 指每年每千人口中的死亡人数。它与出生率一起决定了自然增长率（出生率减去死亡率）。地理学中最简单的公式：自然增长率 = 出生率 - 死亡率。记住，即使差值很小，长期累积也会导致人口的快速增长。
Population pyramid is a bar chart showing the age and sex structure of a population. A wide base signals high birth rates (youthful population), while a narrow base suggests low birth rates (ageing population). Imagine the pyramid shape as a silhouette of a country's future workforce.
人口金字塔 是展示人口年龄与性别结构的条形图。底部宽表示出生率高（年轻型人口），底部窄则表示出生率低（老年型人口）。不妨把金字塔的形状想象成一个国家未来劳动力的轮廓剪影。
Dependency ratio compares the working-age population (15-64) with the dependent groups (0-14 and 65+). A high ratio means each worker has to support more dependants. Link the word 'depend' – these groups depend on others for food, housing and care.
抚养比 将劳动年龄人口（15-64 岁）与受抚养群体（0-14 岁和 65 岁以上）进行对比。高抚养比意味着每个劳动者需要养活更多的受抚养人口。可联系 '依赖' 一词——这些群体的衣食住行和照护都依赖于他人。
2. Migration and Urbanisation | 迁移与城市化
Migration is the permanent or semi-permanent movement of people from one place to another. Immigration (moving in) and emigration (moving out) are easy to confuse: just think of 'im-' as 'in' and 'e-' as 'exit'.
迁移 指人口从一个地方到另一个地方的永久性或半永久性移动。迁入 和 迁出 容易混淆：只需记住 'im-' 是 '进入'，'e-' 是 '出去'。
Push-pull factors explain why people migrate. Push factors (such as unemployment, war, natural disasters) drive people away; pull factors (such as job opportunities, safety, better education) attract them to a new destination. Visualise a hand pushing a person from behind and another pulling them forward.
推拉因素 用于解释迁移原因。推力因素（如失业、战争、自然灾害）把人推离原地；拉力因素（如就业机会、安全环境、更好的教育）把人吸引到新目的地。可以想象一只手从背后推人，另一只手从前方拉人。
Urbanisation is the increase in the proportion of people living in urban areas compared to rural areas. It is not simply growth of cities, but a shift in the balance of where people live. Counter-urbanisation is the movement of people out of cities into the countryside, often in search of a quieter lifestyle.
城市化 指城镇人口占总人口比例的上升过程。这不单是城市面积的扩大，更是人口居住地平衡的转变。逆城市化 则是人们离开城市迁往乡村的移动，通常是为了寻求更宁静的生活方式。
3. Settlement Patterns and Site Factors | 聚落模式与选址因素
Site refers to the exact physical characteristics of the place where a settlement is located, such as flat land, water supply or defensive advantages. Think of the 'site' as the ground beneath your feet. Situation describes the settlement's location relative to other places, like its position along a trade route or near a river crossing.
位置 (site) 指的是聚落所在地的具体自然特征，例如平地、水源或防御优势。可以把 'site' 想象成脚下的土地。境况 (situation) 则描述该聚落相对于其他地方的位置，比如它是否位于商路沿线或靠近河流渡口。
Settlement hierarchy orders settlements by size and services: isolated dwelling, hamlet, village, town, city. The higher up the hierarchy, the higher the threshold population (the minimum number of people needed to support a service) and the larger the sphere of influence (the area people travel from to use a service). Recall 'hierarchy' as a ladder – each step up means more shops, schools and hospitals.
聚落等级体系 按规模和服务对聚落进行排序：独户、小村庄、村庄、镇、城市。在等级中越往上，门槛人口（支撑某项服务所需的最低人口数量）越高，影响范围（人们前来使用该服务的区域）也越大。可以把 '等级' 想象成一把梯子——每上一级，意味着更多的商店、学校和医院。
4. River Processes and Landforms | 河流作用与地貌
Erosion is the wearing away of the land. River erosion works through four main processes: hydraulic action, abrasion, attrition and solution. To remember them, use the acronym HAAS: Hydraulic action (force of water), Abrasion (sandpaper effect of load), Attrition (rocks hitting each other), Solution (slightly acidic water dissolving rocks).
侵蚀 是土地被磨损的过程。河流侵蚀主要通过四种方式进行：水力作用、磨蚀、磨圆和溶蚀。可以用缩写 HAAS 来记忆：Hydraulic action（水力冲击）、Abrasion（砂纸研磨作用）、Attrition（石块互相碰撞磨圆）、Solution（弱酸性河水溶解岩石）。
Transportation ion (fine sediment carried within the water) and solution (dissolved minerals). Think of a traffic light for size: Traction = biggest (lorries), Saltation = medium (cars), Suspension = smallest (bikes).
搬运 指被侵蚀物质的移动过程。四种方式：推移（大石块沿河床滚动）、跃移（小卵石跳跃前进）、悬移（细颗粒悬浮在水中）、溶运（溶解矿物质）。可按大小想象成交通灯：Traction 最大（卡车），Saltation 中等（小汽车），Suspension 最小（自行车）。
Deposition occurs when a river loses energy and drops its load. The heaviest material is deposited first. Key landforms created by deposition include meanders (bends in the river), oxbow lakes (horseshoe-shaped lakes formed from cut-off meanders), floodplains and deltas (fan-shaped deposits at the river mouth). Picture a delta as the Greek letter Δ – a triangular spread of sediment into the sea.
沉积 发生在河流能量减弱并卸下其携带物时，最重的物质最先沉积。由沉积作用形成的主要地貌有：曲流（河道弯曲处）、牛轭湖（由截弯取直形成的马蹄形湖泊）、河漫滩 和 三角洲（河口处的扇形沉积体）。可把三角洲想象成希腊字母 Δ——沉积物呈三角形向海洋扩散。
5. Coastal Processes and Landforms | 海岸作用与地貌
Constructive waves have a strong swash and weak backwash, so they deposit more material than they remove, building up beaches. Destructive waves have a strong backwash, eroding the coast. A simple memory aid: 'Constructive creates beaches (C for create), Destructive destroys them (D for destroy).'
建设性波浪 上冲流强而回流弱，因此沉积的物质多于带走的物质，会堆积出沙滩。破坏性波浪 回流强劲，会侵蚀海岸。简单记忆法：'建设性 (Constructive) 创造 (Create) 沙滩，破坏性 (Destructive) 破坏 (Destroy) 沙滩。'
Longshore drift is the movement of sand and pebbles along the coast by waves approaching at an angle. Swash pushes material up the beach at an angle, backwash drags it straight down; the resulting zigzag pathway moves sediment along the shore. Imagine a conveyor belt carrying sand sideways along the beach.
沿岸漂移 是指在海浪以一定角度冲上岸时，沙砾沿海岸线移动的过程。上冲流将物质斜向推上海滩，回流又将其垂直带回海中；这种锯齿状的路径使沉积物沿滨线横向移动。可以把它想象成一条沿沙滩侧向输送沙子的传送带。
Erosional landforms include caves, arches, stacks and stumps – often formed on headlands. The sequence is easy: crack, cave, arch, stack, stump. Remember it as 'C-C-A-S-S'. Depositional landforms include spits (a narrow ridge of sand or shingle extending from the shore) and bars (a spit that has grown across a bay).
侵蚀地貌包括海蚀洞、海蚀拱、海蚀柱 和 海蚀残丘，常形成于海岬。演变顺序容易记：裂隙、海蚀洞、海蚀拱、海蚀柱、海蚀残丘。可记为 'C-C-A-S-S'。堆积地貌包括沙嘴（从岸边伸出的狭窄沙砾脊）和 沙坝（沙嘴横跨海湾生长而成的坝状堆积体）。
6. Weather and Climate | 天气与气候
Weather describes day-to-day atmospheric conditions, while climate is the average weather over a long period (at least 30 years). Think of weather as your mood today and climate as your personality over a lifetime.
天气 描述的是每日的大气状况，而 气候 是长期（至少30年）的天气平均状态。可以把天气想象成你今天的心情，气候则是你一生中的性格。
Key instruments include: thermometer (temperature), barometer (air pressure), rain gauge (precipitation) and anemometer (wind speed). The anemometer often trips students up: 'anemo-' sounds like 'animal' – nothing to do with animals! Actually it comes from the Greek 'anemos' meaning wind. Picture a spinning wind turbine to recall its function.
主要仪器包括：温度计（气温）、气压计（气压）、雨量计（降水量）和 风速计（风速）。风速计 (anemometer) 常常难倒学生：'anemo-' 听起来像 'animal'——可跟动物完全无关！它其实源自希腊语 'anemos'，意为 '风'。想象转动着的风力涡轮机，就能想起它的功能。
7. Ecosystems and Biomes | 生态系统与生物群系
An ecosystem is a community of living organisms interacting with each other and their non-living environment. A biome is a large-scale ecosystem defined by its climate and dominant vegetation, such as tropical rainforest, tundra or desert. To differentiate: a pond is an ecosystem; the savanna is a biome.
生态系统 是生物群落与其非生物环境相互作用的共同体。生物群系 则是由气候和优势植被决定的大尺度生态系统，如热带雨林、苔原或沙漠。区分方法：一个池塘是一个生态系统；稀树草原是一个生物群系。
Food chain shows a single pathway of energy transfer, while a food web connects several food chains together. The nutrient cycle describes how nutrients move through the soil, vegetation, litter and rock weathering. It is often drawn as a circle with arrows between stores. Think of it as a recycling symbol for nature.
食物链 显示能量流动的单一途径，而 食物网 将多条食物链连接在一起。营养循环 描述养分如何在土壤、植被、枯枝落叶和岩石风化之间移动。它常被画成一个在储存库之间有箭头连接的圆圈。可以把它想成是大自然的回收标志。
8. Economic Activity and Development | 经济活动与发展
Economic sectors are classified as primary (extracting raw materials, e.g. farming, mining), secondary (manufacturing, e.g. car assembly), tertiary (services, e.g. teaching, retail) and quaternary (knowledge-based high-tech, e.g. research and IT). Remember the first letter of each: P-S-T-Q – think of it as a 'Past-Slow-to-Quick' model of economic evolution.
经济部门分为第一产业（获取原材料，如农业、采矿）、第二产业（制造业，如汽车组装）、第三产业（服务业，如教育、零售）和 第四产业（知识型高科技产业，如研发和信息技术）。记住首字母：P-S-T-Q，可把它想象成经济演变的 '从过去到缓慢再到快速' 的模式。
Development indicators include GDP (Gross Domestic Product – total value of goods and services produced in a country), GNI (Gross National Income – GDP plus income from abroad) and HDI (Human Development Index – a composite of life expectancy, education and income). HDI is the broadest measure; the three components can be recalled as 'Health, Education, Wealth'.
发展指标包括GDP（国内生产总值——一国生产的商品和服务总价值）、GNI（国民总收入——GDP 加上海外收入）和 HDI（人类发展指数——由预期寿命、教育和收入组成的综合指标）。HDI 是最全面的衡量指标；其三个组成部分可记为 '健康、教育、财富'。
9. Globalisation and Transnational Corporations | 全球化与跨国公司
Globalisation is the increasing interconnectedness of the world through flows of trade, investment, information and people. A Transnational Corporation (TNC) is a company that operates in more than one country, such as Nike or Toyota. TNCs are key drivers of globalisation because they organise production and sales across borders.
全球化 指通过贸易、投资、信息和人员流动，世界日益紧密相连的过程。跨国公司 (TNC) 是在多个国家经营的企业，如耐克或丰田。跨国公司是全球化的重要驱动力，因为它们跨边界组织生产和销售。
Foreign Direct Investment (FDI) is when a company invests money into a business in another country, often by setting up factories or offices. It is a strong indicator of global economic integration. Think of FDI as a company 'planting its flag' in a new country to grow its market.
外商直接投资 (FDI) 是一家公司向另一国家的企业投入资金，通常是通过设立工厂或办事处的方式。它是全球经济一体化的重要指标。可以把 FDI 想象成一家公司在新国家 '插上旗帜' 以拓展市场。
10. Environmental Management and Sustainability | 环境管理与可持续性
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It balances three pillars: environment, economy and society. The 'three-legged stool' analogy is a useful visual – if one leg is too short, development is unstable.
可持续发展 是既满足当代人需求，又不损害子孙后代满足其自身需求的能力的发展。它平衡着三大支柱：环境、经济和社会。'三脚凳' 的比喻很好用——如果一条腿太短，发展就不稳固。
Carbon footprint is the total amount of greenhouse gases produced directly and indirectly by human activities, usually measured in tonnes of CO₂ equivalent. Renewable resources (solar, wind, water) can be replenished naturally; non-renewable resources (coal, oil, natural gas) are finite. Remember that 'renew' means 'to make new again'.
碳足迹 是人类活动直接和间接产生的温室气体总量，通常以二氧化碳当量吨数来衡量。可再生资源（太阳能、风能、水能）可以自然补充；不可再生资源（煤、石油、天然气）则是有限的。记住 'renew' 意为 '重新更新'。
Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas, often caused by overgrazing, deforestation and poor agricultural practices. Deforestation is the large-scale removal of trees, often to clear land for farming or to harvest timber. Both terms start with 'de-' (meaning removal) – desertification 'removes' fertile land; deforestation 'removes' forests.
荒漠化 是干旱、半干旱和亚湿润地区土地退化的过程，常由过度放牧、森林砍伐和不当农业措施引起。森林砍伐 是大规模移除树木的行为，通常是为了开垦农田或获取木材。两个词都以 'de-'（意为 '去除'）开头——荒漠化 '去除' 了肥沃土地；森林砍伐 '去除' 了森林。
11. Hazardous Environments | 灾害环境
A natural hazard is a natural event that threatens people and property. When it causes significant damage, loss of life and disruption, it becomes a disaster the vulnerability of the population. Think of the formula: Risk = Hazard × Vulnerability.
自然灾害 指威胁人类生命财产的自然事件。当它造成重大破坏、人员伤亡和社会混乱时，便成为 灾害。风险是灾害本身与人口脆弱性共同作用的结果。可记为公式：风险 = 灾害 × 脆弱性。
Mitigation refers to actions taken to reduce the impact of hazards (e.g. building earthquake-resistant structures), while prediction involves forecasting when and where a hazard might occur. Mitigation is 'preparing for the punch'; prediction is 'seeing the punch coming'. Both are essential for reducing disaster risk.
减灾 指为降低灾害影响而采取的行动（如建造抗震建筑），而 预测 则是预报灾害可能发生的时间和地点。减灾好比 '做好挨拳的准备'；预测则是 '看见拳头打来'。两者都是减少灾害风险的关键。
12. Map Skills and Fieldwork Vocabulary | 地图技能与实地调查词汇
Key map skills terms include grid reference (a six-figure coordinate that pinpoints a location on an Ordnance Survey map), scale (the ratio between a distance on the map and the corresponding distance on the ground) and cross-section (a side view of the landscape, drawn from contour lines). To write a six-figure grid reference, remember 'along the corridor, then up the stairs'.
关键的地图技能术语包括 格网参考（在测量地图上精确定位的六位数字坐标）、比例尺（地图上距离与实地对应距离的比率）以及 剖面图（根据等高线绘制的景观侧视图）。要写出六位格网参考，记住 '先沿走廊走，再上楼' 的口诀。
Fieldwork vocabulary includes primary data (data collected first-hand, e.g. questionnaires, measurements) and secondary data (data from existing sources, e.g. census, textbooks). Sampling methods can be random, systematic or stratified. Link 'primary' with 'personal' – it is data you have collected yourself.
实地调查词汇包括一手数据（亲自收集的数据，如问卷、测量值）和 二手数据（来自已有资料的数据，如人口普查、教科书）。抽样方法 有随机抽样、系统抽样和分层抽样。可以将 'primary' 与 'personal' 联系起来——它是你亲自收集的数据。
