1. Map Skills Terminology | 地图技能术语
A four‑figure grid reference gives the square, but a six‑figure grid reference pinpoints an exact location. Mentally walk “along the corridor” (eastings) and then “up the stairs” (northings); the third and sixth digits divide each grid square into ten imaginary lines.
四位数字网格参考给出方格区域，六位数字网格参考则能精确锁定地点。心中先“沿着走廊走”（读东距数值），再“上楼”（读北距数值）；第三个和第六位数字把每个网格方格细分成十个等分线。
close together, the slope is steep; when they spread wide apart, the land is gentle. Think “close contours = cliff; spaced contours = flat”.
等高线连接海拔高度相等的点。等高线密集表示陡坡，间距宽表示平缓地形。记住“等高线密如悬崖，疏如平地”。
Scale is expressed as a ratio, such as 1:25,000, which means 1 cm on the map represents 25,000 cm – or 250 metres – on the ground. To convert quickly, delete the last two zeros of the scale number to get metres.
比例尺用比数表示，如1:25,000，意为图上1厘米代表实地25,000厘米，即250米。快速换算时，将比例尺数字去掉最后两个零就得到米数。
2. Coastal Processes and Landforms | 海岸过程与地貌术语
The four types of coastal erosion can be remembered with the acronym HAAS: Hydraulic Action (water blasts air into cracks), Abrasion (rocks scrape like sandpaper), Attrition (stones collide and become rounded) and Solution (mild acids dissolve limestone).
四种海岸侵蚀类型可用首字母缩写HAAS来记忆：水力作用（水把空气压入裂缝）、磨蚀（岩石像砂纸一样刮削）、磨损（石头互相碰撞变圆）和溶蚀（弱酸溶解石灰岩）。
Longshore drift moves sediment in a zig‑zag pattern: the swash rushes up the beach at an angle, but the backwash drags straight back down with gravity. The net effect is a “conveyor belt” carrying sand along the coast.
沿岸漂沙以锯齿状路径搬运泥沙：冲流以一定角度冲上海滩，而回流在重力作用下沿直线退回海中。最终效果就像一条“传送带”把沙子沿海岸输送。
Headlands and bays form where bands of hard and soft rock alternate. The hard rock resists erosion and juts out as a headland, while the soft rock retreats into a bay. Caves, arches, stacks and stumps then develop in this order on headlands.
当硬岩和软岩交替分布时，会形成岬角和海湾。硬岩抗侵蚀能力强，突出为岬角；软岩后退形成海湾。在岬角上会依次发育出海蚀洞、海蚀拱、海蚀柱和海蚀墩。
3. River Environments | 河流环境术语
A drainage basin is the area of land drained by a river and its tributaries. The boundary of a basin is called the watershed. Picture it as a bowl: rain falling inside the bowl flows to the main river; rain outside drains elsewhere.
流域是指一条河流及其支流排水的陆地区域。流域的边界称为分水岭。想象一个碗：落在碗里的雨水汇入干流，落在碗外的水则流向他处。
River transportation involves four processes: traction (large boulders rolled along the bed), saltation (small stones bounced), suspension (fine silt carried in the water) and solution (dissolved minerals). The memory chain “Big, Bounce, Float, Fizz” helps sequence them by size.
河流搬运有四种过程：推移（大石球沿河床滚动）、跃移（小石子跳跃前进）、悬移（细粉砂悬浮在水中）和溶移（溶解矿物质）。用“大、跳、漂、泡”的口诀可以按颗粒大小记住顺序。
Meanders are bends in a river’s course. On the outside bend, faster water erodes a river cliff; on the inside bend, slower water deposits a slip‑off slope. Eventually, the neck of a meander may be cut through, forming an oxbow lake.
曲流是河道的蜿蜒弯曲段。在凹岸（外弯），流速较快的水流侵蚀出陡岸；在凸岸（内弯），流速较慢的水流沉积出平缓的边滩。随着时间推移，曲流颈可能被截弯取直，形成牛轭湖。
4. Weather and Climate | 天气与气候术语
Weather describes short‑term atmospheric conditions – what you see outside your window today. Climate is the long‑term average of weather over at least 30 years. The classic memory phrase is: “Climate is what you expect, weather is what you get.”
天气描述短期大气状况——你今天窗外看到的就是天气。气候则是至少30年天气的长期平均状况。经典的记忆口诀是：“气候是你预期的，天气是你遇到的。”
The UK experiences three main types of rainfall. Relief rainfall occurs when warm, moist air is forced to rise over hills. Frontal rainfall happens where a warm air mass meets a cold air mass. Convectional rainfall is caused by the sun heating the ground. Think “Hills, Fronts, Hot ground”.
英国主要有三种降水类型。地形雨是暖湿空气被迫抬升越过山丘时形成；锋面雨发生在暖气团与冷气团相遇时；对流雨由太阳加热地面引起。联想“山、锋、热”三个字就能区分。
An air mass is a huge body of air with similar temperature and humidity. The UK is affected by polar maritime (PM) air bringing cold, wet weather, and tropical maritime (TM) air bringing mild, damp conditions. Remember PM as “polar‑cold, maritime‑wet”.
气团是具有相似温度和湿度的一大团空气。英国受极地海洋气团（PM）影响带来寒冷潮湿天气，受热带海洋气团（TM）影响带来温和湿润条件。记住PM就是“极地冷、海洋湿”。
5. Population Dynamics | 人口动态术语
Natural increase is calculated simply:
Natural Increase = Birth Rate – Death Rate
自然增长率计算很简单：
自然增长率 = 出生率 – 死亡率
If births outnumber deaths, the population grows naturally; if deaths exceed births, natural decrease occurs. The rate is expressed per 1,000 people per year.
如果出生人数多于死亡人数，人口自然增长；反之则出现自然减少。该比率通常表示为每千人每年。
The Demographic Transition Model (DTM) shows how birth and death rates change as a country develops. The five stages run from high fluctuating (Stage 1) to low fluctuating (Stage 4) and possible natural decrease (Stage 5). A handy story: “Famine, Falling, Fertile, Flat, Fewer”.
人口转变模型（DTM）展示了一个国家发展过程中出生率和死亡率的变化。五个阶段依次是高位震荡（阶段1）、早期下降、后期下降、低位震荡和可能的人口减少（阶段5）。可以记成：“饥荒、下降、多产、平稳、减少”。
A population pyramid with a wide base indicates a high proportion of young people and rapid growth – an expansive pyramid. A narrow base suggests an ageing population and low growth (constrictive). Stationary pyramids have relatively even sides. Picture the shape telling the story.
底宽的人口金字塔表示年轻人比例高，增长迅速，称为扩张型。底部狭窄则暗示人口老龄化、低增长（收缩型）。静止型金字塔边部相对均匀。图形本身就是最好的速记符号。
6. Settlement and Urbanisation | 聚落与城市化术语
A settlement hierarchy ranks places by size and importance: isolated dwelling, hamlet, village, town, city, conurbation. As you go up the hierarchy, the number of settlements decreases but the range of services increases. Think “Small place, few services; big city, many services.”
聚落等级按规模和重要性排序：独户住宅、小村落、村庄、镇、城市、大都市带。等级越高，聚落数量越少，但服务种类越多。可以记作“小地方服务少，大城市服务多”。
Urbanisation is the increase in the proportion of people living in towns and cities. Suburbanisation is the movement of people from inner cities to the suburbs. Counter‑urbanisation is migration from urban to rural areas. The sequence “Urban–Suburban–Counter” spells out the outward spread.
城市化是指城镇人口比例上升。郊区化指人口从市中心迁往郊区。逆城市化则是从城市地区迁往农村地区。按照“城市—郊区—反方向”的顺序，就是人口向外扩散的过程。
The Burgess model imagines a city as a set of concentric rings: the Central Business District (CBD) in the middle, followed by inner city, then lower‑class and middle‑class residential zones, and finally the commuter zone. A target‑shaped diagram makes it easy to sketch from memory.
伯吉斯模型将城市想象为同心圆圈：中央商务区（CBD）居中，向内依次是内城区、低阶层住宅区、中阶层住宅区，最外层是通勤区。把城市画成一个靶子，就很容易凭记忆复现出来。
7. Economic Activities and Development | 经济活动与发展术语
Economic sectors describe the type of work. Primary industry extracts raw materials (farming, mining). Secondary industry manufactures goods (factories). Tertiary provides services (retail, teaching). Quaternary involves research and IT. The simple chain: “Extract, Make, Serve, Think.”
经济产业部门描述工作类型。第一产业提取原材料（农业、采矿），第二产业制造产品（工厂），第三产业提供服务（零售、教学），第四产业涉及研发和信息技术。记住链条：“提取、制造、服务、思考”。
Development is measured by indicators such as GNI per capita, literacy rate, life expectancy and the Human Development Index (HDI). HDI combines life expectancy, education and income into a single score between 0 and 1. It reminds us that development is about more than just money.
发展程度通过人均国民总收入、识字率、预期寿命和人类发展指数（HDI）等指标衡量。HDI将预期寿命、教育和收入综合成一个0到1之间的数值，提醒我们发展不只看金钱。
Globalisation is the increasing connections between countries through trade, transport and technology. Transnational corporations (TNCs) operate in many countries, linking economies. A useful metaphor is “the world shrinking into a village” – a global village.
全球化是指各国之间通过贸易、交通和科技日益紧密的联系。跨国公司在多个国家经营，将经济体连接起来。一个有用的比喻是“世界缩小成一个村庄”——地球村。
8. Climate Change and Sustainability | 气候变化与可持续性术语
The natural greenhouse effect traps some heat and keeps Earth warm. The enhanced greenhouse effect is caused by extra greenhouse gases, such as CO₂ and methane, from human activities. Remember: “Natural keeps us alive, enhanced makes the planet fry.”
天然的温室效应截留部分热量，使地球保持温暖。增强的温室效应则由人类活动额外排放的二氧化碳和甲烷等温室气体造成。记住：“天然让生命延续，增强让地球变暖”。
A carbon footprint is the total amount of greenhouse gases produced directly and indirectly by a person, event or product. Reducing it involves using less energy, eating less meat and choosing sustainable transport. The footprint image is a powerful memory hook.
碳足迹指一个人、一项活动或一个产品直接和间接产生的温室气体总量。减少碳足迹需要节约能源、少吃肉类、选择可持续交通。脚踩CO₂的脚印画面本身就是强大的记忆钩子。
In tackling climate change, mitigation means reducing the causes, such as switching to renewable energy. Adaptation means adjusting to the effects, like building flood defences. The pair “Mitigate the cause, Adapt to the effect” keeps them straight.
应对气候变化时，减缓（mitigation）指从源头减少成因，例如改用可再生能源；适应（adaptation）指针对影响做出调整，例如修建防洪设施。用“减缓成因，适应后果”就能分清。
9. Natural Hazards | 自然灾害术语
Earthquakes and volcanoes often occur along plate boundaries. Destructive boundaries involve plates colliding; constructive boundaries move apart; conservative boundaries slide past each other. Think “Crash, Crack, Slide” for the three types.
地震和火山往往发生在板块边界。破坏性边界板块碰撞，建设性边界板块分离，保守型边界板块水平错动。用“撞、裂、滑”三个字就能区分三种类型。
A tropical storm forms over warm ocean water when the temperature exceeds 27°C. The storm features an eye, a calm centre, surrounded by a violent eyewall. The energy comes from the release of latent heat as moist air rises and condenses.
热带风暴在海水温度超过27°C的暖洋面上形成。风暴中心有一个平静的风眼，四周是狂风暴雨的眼壁。其能量来源于暖湿空气上升凝结时释放的潜热。
Hazard management involves the three Ps: Prediction, Preparation and Prevention. Prediction uses technology to forecast events; preparation includes drills and emergency kits; prevention tries to reduce risk, e.g. building earthquake‑resistant structures.
灾害管理可以概括为三个P：预测（Prediction）、防备（Preparation）和预防（Prevention）。预测用技术提前预报；防备包括演练和应急包；预防旨在降低风险，比如建造抗震建筑。
10. Fieldwork and Enquiry Skills | 野外调查与探究技能术语
llected by someone else, such as census statistics or articles. The clue is in the prefix: “Primary = my own; Secondary = someone else’s.”
一手数据是你自己通过问卷、计数或测量直接收集的信息。二手数据是他人收集的，如人口普查统计或文章。前缀透露了线索：“一手是我自己的，二手是别人的”。
Sampling techniques help you collect data fairly: random sampling gives every site an equal chance; systematic sampling uses a regular interval, often along a transect; stratified sampling ensures different groups are represented proportionally. A catchy prompt is “Random chance, Systematic space, Stratified share.”
采样方法帮助你公平地收集数据：随机采样让每个点机会均等；系统采样按固定间隔选择，常沿样线进行；分层采样确保不同群体按比例代表。可以记成：“随机靠运气，系统靠间距，分层靠比例。”
A risk assessment identifies possible hazards during fieldwork, rates their likelihood and severity, and describes what you will do to control them. Always complete one before leaving the classroom – it is your safety checklist.
风险评估识别野外考察期间可能的危险，评定其发生的可能性和严重程度，并说明控制措施。走出教室前一定要完成风险评估——它就是你的安全核查表。
