1. What is Geography? | 什么是地理学？
Geography is the study of the Earth’s surface, its physical features, and how humans interact with their environment. It is divided into two main branches: physical geography, which examines natural processes such as weather, rivers and landforms, and human geography, which explores people, settlements, economies and cultures. Through geography, we learn to appreciate the interconnectedness of our world and make sense of patterns we see around us every day.
地理学是研究地球表面、自然特征以及人类与环境相互作用的学科。它分为两大分支：自然地理研究天气、河流和地貌等自然过程，人文地理则探讨人口、聚落、经济和文化。通过学习地理，我们能够认识世界的相互联系，理解日常生活中观察到的格局。
In CAIE Year 7, you will begin by asking geographical questions such as ‘Where is it?’, ‘Why is it there?’ and ‘How does it affect people?’ This enquiry-based approach trains you to think like a geographer and encourages you to investigate real-world issues using evidence.
在CAIE七年级课程中，你将开始提出地理问题，例如“它在哪？”“它为什么在那里？”以及“它如何影响人类？”。这种探究式学习方法训练你像地理学者一样思考，并鼓励你用证据研究现实问题。
2. Map Skills: Compass and Grid References | 地图技能：指南针与网格参考
A fundamental skill in geography is reading and interpreting maps. You must be comfortable with the eight points of the compass (N, NE, E, SE, S, SW, W, NW) to describe directions. This allows you to explain, for example, that a river flows from the northeast to the southwest relative to a town.
地理学的一项基本技能是阅读和解读地图。你必须熟练使用八位罗盘（北、东北、东、东南、南、西南、西、西北）来描述方向。这样你就可以解释，比如一条河相对于某个小镇从东北向西南流动。
Grid references let you pinpoint exact locations. Four-figure grid references (e.g. 1924) identify a grid square, while six-figure references (e.g. 194245) give a more precise location within that square. Remember the rule ‘along the corridor and up the stairs’ – read the easting first, then the northing.
网格参考让你能够精确定位。四位网格参考（如1924）确定一个网格方格，六位参考（如194245）则给出该方格内更精确的位置。记住“先横后纵”的规则——先读东经坐标，再读北纬坐标。
| Feature | Four-figure | Six-figure |
|---|---|---|
| School | 4823 | 487235 |
| Church | 5021 | 508212 |
Practise map reading using Ordnance Survey or similar topographic maps over the summer. Try describing the direction from your home to a local park using compass points and give its grid reference.
暑假期间使用地形图练习读图。尝试用罗盘方位描述从你家到当地公园的方向，并给出它的网格参考。
3. The Earth’s Structure and Tectonic Plates | 地球结构与其板块构造
The Earth is made up of four main layers: the inner core, outer core, mantle and crust. The crust is the thin, solid outer shell we live on, and it is broken into large pieces called tectonic plates. These plates float on the semi-molten mantle and move very slowly over time.
地球由四个主要层圈组成：内核、外核、地幔和地壳。地壳是我们居住的薄而坚硬的外壳，它碎裂成称为构造板块的巨大块体。这些板块漂浮在半熔融的地幔上，随时间极其缓慢地移动。
Plate movements are caused by convection currents in the mantle. Where plates meet, we find boundaries: constructive (plates move apart, creating new crust), destructive (plates collide, one sinks beneath the other), and conservative (plates slide past each other). Most earthquakes and volcanoes occur along these boundaries.
地幔中的对流驱动了板块运动。板块交界处有不同类型：建设性边界（板块分离，形成新地壳）、破坏性边界（板块碰撞，一块俯冲到另一块之下）和保守性边界（板块相互滑动）。大多数地震和火山都发生在这些边界上。
Understanding plate tectonics helps explain the distribution of mountains, ocean trenches and volcanic islands. When studying CAIE Geography, you will also consider how these natural hazards affect people living in danger zones.
理解板块构造有助于解释山脉、海沟和火山岛的分布。在学习CAIE地理时，你还会思考这些自然灾害如何影响生活在危险区的人们。
4. Rocks, Weathering and Erosion | 岩石、风化与侵蚀
Rocks are naturally occurring aggregates of minerals. The three main rock types are igneous (formed from cooled magma, e.g. granite), sedimentary (formed from compressed layers of sediment, e.g. limestone) and metamorphic (formed when existing rocks are changed by heat and pressure, e.g. marble).
岩石是天然形成的矿物集合体。三大岩石类型包括：火成岩（由冷却的岩浆形成，如花岗岩）、沉积岩（由沉积物层层压实形成，如石灰岩）和变质岩（由原有岩石受热和压力变质而成，如大理岩）。
Weathering breaks down rocks in situ, without movement. Physical weathering (e.g. freeze-thaw) increases cracks, chemical weathering (e.g. acid rain dissolving limestone) changes the rock’s composition, and biological weathering (e.g. plant roots) involves living organisms. Erosion, on the other hand, involves movement: water, wind and ice carry away broken material.
风化在原地破碎岩石而不发生移动。物理风化（如冻融作用）使裂隙扩大，化学风化（如酸雨溶解石灰岩）改变岩石成分，生物风化（如植物根系）涉及生物作用。而侵蚀则包括移动：水、风和冰将破碎物质搬运走。
A simple summer activity is to find different stones in your garden or local area, identify their type and look for signs of weathering, such as rounded edges or discolouration.
一个简单的暑期活动是在自家花园或本地寻找不同的石头，识别它们的类型，并寻找风化迹象，如圆滑的棱角或变色。
5. Rivers: From Source to Mouth | 河流：从源头到河口
A river’s journey begins at its source, usually in high ground, and ends at its mouth where it enters a lake or sea. The long profile of a river can be divided into the upper, middle and lower courses, each with distinct features and processes.
河流的旅程从源头开始，通常在较高的地方，最终在河口注入湖泊或海洋。河流的纵剖面可分为上游、中游和下游，每个河段具有不同的特征和过程。
In the upper course, vertical erosion dominates, creating V-shaped valleys, waterfalls and rapids. As the river flows into the middle course, it begins to meander, and lateral erosion widens the valley. In the lower course, deposition forms floodplains, levees and deltas. The key processes are erosion, transportation (traction, saltation, suspension, solution) and deposition.
上游以垂直侵蚀为主，形成V形谷、瀑布和急流。进入中游，河流开始蜿蜒，侧蚀拓宽河谷。下游则以沉积为主，形成泛滥平原、天然堤和三角洲。关键过程包括侵蚀、搬运（推移、跃移、悬移、溶解）和沉积。
The hydrological cycle connects rivers to the atmosphere. Water evaporates from oceans and land, condenses into clouds and falls as precipitation. Some infiltrates soil, some runs off into rivers, completing the cycle.
水循环将河流与大气联系起来。水从海洋和陆地蒸发，凝结成云并以降水形式落下。一部分下渗到土壤，一部分汇入河流，完成循环。
6. Weather, Climate and the Water Cycle | 天气、气候与水循环
Weather refers to the day-to-day conditions of the atmosphere – temperature, precipitation, wind speed and humidity – at a specific place. Climate is the average weather pattern over a long period, usually 30 years, for a region. Understanding the difference helps geographers identify seasonal trends and long-term changes like global warming.
天气是指某地每天的瞬时大气状况——温度、降水、风速和湿度。气候则是一个地区长期（通常30年）的平均天气状况。理解两者的区别有助于地理学家识别季节趋势和全球变暖等长期变化。
The water cycle (hydrological cycle) circulates water between the atmosphere, land and oceans. Key stages: evaporation and transpiration (evapotranspiration), condensation, precipitation, surface runoff, infiltration and groundwater flow. This cycle provides fresh water for rivers, lakes and human use.
水循环（水文循环）使水在大气、陆地和海洋之间循环流动。主要环节：蒸发和蒸腾（蒸散发）、凝结、降水、地表径流、下渗和地下水流。该循环为河流、湖泊和人类用水提供淡水来源。
In CAIE Year 7, you will also study climate graphs, which combine monthly temperature and rainfall data. Learn to read these graphs: the temperature line often uses °C, and rainfall bars are in mm. Try creating a climate graph for your own town using online data.
在CAIE七年级，你还会学习气候图表，它将月均温和降水量数据集于一体。学会阅读这些图表：温度线通常使用°C，而降水量柱状图单位为毫米。尝试使用网上的数据为自己的城镇制作一份气候图。
7. Population: Density and Distribution | 人口：密度与分布
Population distribution describes where people live, while population density measures how many people live in a given area, usually persons per km². Some places, like coasts and fertile river valleys, are densely populated; others, like deserts and high mountains, are sparsely populated.
人口分布描述人们居住在哪里，人口密度则衡量单位面积内居住的人口数量，通常为人/平方公里。某些地方，如沿海地区和肥沃的河谷，人口稠密；另一些地方，如沙漠和高山，则人口稀少。
Physical factors influencing settlement include relief (flat land easier to build on), climate (moderate temperatures and reliable rainfall), soil fertility and water supply. Human factors include job opportunities, transport links and political stability. CAIE geography expects you to explain why population is unevenly distributed using both physical and human reasons.
影响聚落的自然因素包括地形（平坦土地利于建设）、气候（温和的气温和稳定的降水）、土壤肥力和水源供应。人文因素包括就业机会、交通联系和政治稳定性。CAIE地理要求你能够运用自然和人文两方面原因解释人口分布不均衡的现象。
To build your skills, choose two contrasting regions (e.g. the Nile Valley vs the Sahara Desert) and list the reasons for dense and sparse populations.
为锻炼技能，可选择两个截然不同的地区（如尼罗河谷与撒哈拉沙漠），列出人口稠密和稀少的原因。
8. Settlements: Rural and Urban | 聚落：农村与城市
A settlement is a place where people live. They range in size from a single farm (hamlet) to a megacity with millions of inhabitants. The settlement hierarchy ranks them by size and services: isolated dwelling, hamlet, village, town, city and megacity. As you move up the hierarchy, the number of services and the sphere of influence increase.
聚落是人们居住的地方，其规模从单个农庄（小村）到拥有数百万居民的巨型城市不等。聚落等级按规模和服务功能排序：独户住宅、小村、村落、镇、城市和巨型城市。等级越高，服务种类和影响范围越大。
Settlements can be classified by their function: market towns, ports, industrial centres, tourist resorts or administrative capitals. Many settlements have grown where rivers could be forded, at crossroads, or near natural harbours. The shape and pattern of a settlement (nucleated, linear or dispersed) also tell us about its history and geography.
聚落可按功能分类：集镇、港口、工业中心、旅游胜地或行政首都。许多聚落生长在河流可涉水处、道路交会处或天然港口附近。聚落的形态（聚集型、线型或分散型）也揭示了其历史与地理背景。
Over the summer, explore your own town or village. Draw a sketch map labelling its main functions and identify whether it is rural or urban. Consider why people originally settled there.
暑假期间，探索你自己的小镇或村庄。绘制草图并标注其主要功能，判断它是农村还是城市聚落，并思考人们最初为何定居于此。
9. Environmental Issues: Pollution and Conservation | 环境问题：污染与保护
Human activities produce pollution that harms air, water and land. Air pollution, including greenhouse gases like CO₂, contributes to climate change and acid rain. Water pollution from sewage, fertilisers and industrial waste damages aquatic ecosystems and drinking water supplies.
人类活动产生的污染危害空气、水源和土地。空气污染，包括CO₂等温室气体，导致气候变化和酸雨。来自污水、化肥和工业废物的水污染破坏水生生态系统和饮用水供应。
Conservation means managing resources sustainably so that future generations can also benefit. Strategies include renewable energy (solar, wind, hydro), recycling, afforestation and creating protected areas like national parks. The 3Rs – reduce, reuse, recycle – form a simple framework everyone can follow.
保护意味着以可持续方式管理资源，使后代也能受益。策略包括可再生能源（太阳能、风能、水力）、回收利用、植树造林以及建立国家公园等保护区。3R原则——减少使用、重复使用、循环利用——构成了人人都可践行的简单框架。
In CAIE Geography, you will investigate case studies of both local and global environmental challenges. A bridging task could be to research one environmental problem in your country and suggest two realistic solutions.
在CAIE地理中，你将探究本地和全球环境挑战的实例。一项衔接任务可以是研究你所在国家的一个环境问题并提出两个可行的解决方案。
10. Fieldwork Skills for Geographers | 地理学家的野外考察技能
Fieldwork is at the heart of geography. It involves collecting data outside the classroom through observation, measurement, surveys and sketching. You might count traffic, measure a beach profile, interview members of the public or draw annotated field sketches of a landscape.
野外考察是地理学的核心。它包括通过观察、测量、调查和绘制草图在课堂外收集数据。你可能会统计车流量、测量海滩剖面、采访市民或绘制标注好的景观草图。
Good fieldwork begins with a clear enquiry question, such as ‘How does land use change along the high street?’ or ‘Does river depth increase downstream?’ You then collect data systematically, present it using charts or maps and write a conclusion that answers your question.
好的野外考察始于一个清晰的探究问题，如“商业街沿线的土地利用如何变化？”或“河流深度是否向下游增加？”。然后你需要系统收集数据，用图表或地图展示数据，并撰写结论来回答你的问题。
Even without a formal trip, you can practise skills at a local park: measure distances with a trundle wheel, estimate noise levels, note building materials and ask geographical questions. Keep a field journal to record your observations.
即使没有正式的考察旅行，你仍可在本地公园练习技能：用测距轮测量距离、评估噪音水平、记录建筑材料并提出地理问题。记一本野外日志来记录你的观察。
11. Summer Study Tips and Bridging Activities | 暑期学习技巧与衔接活动
To get ahead in Year 7 Geography, build habits that keep you curious. Watch documentaries about landscapes, weather and cultures; read news articles on environmental topics; and practise sketching maps of rooms, gardens or routes you take. These small actions sharpen your spatial thinking and vocabulary.
要在七年级地理中领先，培养保持好奇心的习惯。观看有关景观、天气和文化的纪录片；阅读环境主题的新闻报道；练习绘制房间、花园或路线的地图。这些小小行动能提升你的空间思维和词汇量。
Create a weekly ‘geography moment’: choose one physical or human geography topic, research it for 20 minutes and write a short summary with a labelled diagram. Share your findings with a friend or family member to strengthen your understanding.
打造每周的“地理时刻”：选择一个自然或人文地理主题，花20分钟研究它，并写一篇附有标注图的简短摘要。与朋友或家人分享你的发现以加深理解。
Finally, review key terms from this bridging guide and make flashcards for concepts like ‘tectonic plate’, ‘meander’, ‘population density’ and ‘sustainability’. A strong vocabulary will help you tackle CAIE assessments confidently.
最后，复习这份衔接指南中的关键术语，并为“构造板块”、“曲流”、“人口密度”、“可持续发展”等概念制作抽认卡。扎实的词汇将帮助你自信地应对CAIE评估。
