Year 7 CIE 地理课程向同学们介绍理解周围世界所需的关键概念和技能。从地图阅读到理解自然过程和人类活动，这一年为未来的地理学习奠定坚实基础。本文梳理了核心知识点，以清晰的中英文解释帮助同学们巩固所学。
1. Introduction to Geography | 地理学入门
Geography is divided into two main branches: physical geography, which studies the natural environment (landforms, climate, rivers), and human geography, which examines how people live and interact with the environment (population, settlements, economies).
地理学主要分为两大分支：自然地理，研究自然环境（地貌、气候、河流）；人文地理，研究人类如何生活并与环境互动（人口、聚落、经济）。
In Year 7, we explore why it is important to ask ‘where’, ‘why’, and ‘how’ about places and patterns on Earth.
在 Year 7，我们要学会对地球上的地点和格局提出“在哪里”、“为什么”和“如何”等问题。
2. Map Skills: The Language of Geographers | 地图技能：地理学家的语言
All geographers need to read and interpret maps. A map is a simplified plan of an area, drawn to scale and using symbols to represent real-world features.
每位地理学家都需要阅读和解释地图。地图是按比例绘制的区域简化平面图，用符号表示真实世界的地物。
A good map always includes a title, a key (legend), a scale, and often a north arrow. Without these elements, understanding location and distance becomes impossible.
一个好的地图总要包含标题、图例、比例尺，常常还有指北箭头。缺少这些要素，理解位置和距离就无从谈起。
- Key or legend explains the symbols used.
- 图例解释所用符号的含义。
- Scale shows the relationship between map distance and real ground distance.
- 比例尺显示图上距离与实际地面距离的关系。
- North arrow indicates direction to help orient the map.
- 指北箭头指示方向，帮助确定地图方位。
3. Direction and Grid References | 方向与网格参考
Compass points are used to describe direction: the four cardinal points are North, East, South, and West, with inter-cardinal points such as North-East in between. Being able to state, for example, that a school is north-west of a park is a fundamental skill.
罗盘方位用于描述方向：四个基本方位是北、东、南、西，其间还有东北等中间方位。能够说出例如学校在公园的西北方，是一项基本技能。
Ordnance Survey (OS) maps use grid references to pinpoint exact locations. A four-figure grid reference (e.g., 1532) locates a grid square, while a six-figure grid reference (e.g., 153325) locates a precise point within that square. Remember to ‘go along the corridor and up the stairs’ – read eastings first, then northings.
地形测量地图使用网格参考精确定位。四位网格参考（如 1532）定位一个网格格网，六位网格参考（如 153325）则定位格网内的精确点。记住“先向右走再向上走”的原则——先读取东向坐标，再读北向坐标。
4. Scale, Distance and Relief | 比例尺、距离与地形
Map scales are expressed in three ways: as a statement (e.g., 1 cm represents 1 km), as a ratio or representative fraction (1:100 000), or as a linear scale bar. Always convert measured distances on a map to real-world distances using the given scale.
比例尺有三种表达方式：文字式（如 1 cm 代表 1 km）、比值式或分数式比例尺（1:100 000）、线段式比例尺。必须用给出的比例尺将图上测量的距离换算为真实世界的距离。
Relief refers to the shape and height of the land. Contour lines are lines joining points of equal height above sea level. Closely spaced contour lines indicate a steep slope, while widely spaced lines show a gentle slope. Spot heights and layer colouring also help to show relief.
地形指陆地的形状和高度。等高线是连接海平面以上等高点位的线。等高线密集表示陡坡，稀疏表示缓坡。注记高程和分层设色也有助于显示地形。
5. The Structure of the Earth | 地球的结构
The Earth is made up of four layers: the inner core (solid iron and nickel), the outer core (liquid), the mantle (semi-molten rock), and the crust (thin, solid outer layer). The crust is broken into large pieces called tectonic plates, which float on the mantle.
地球由四层构成：内核（固态铁镍）、外核（液态）、地幔（半熔融岩石）和地壳（薄而坚固的外层）。地壳破裂成大块的构造板块，漂浮在地幔之上。
Convection currents in the mantle cause these plates to move, leading to earthquakes and volcanic activity at plate boundaries.
地幔中的对流驱动板块运动，在板块边界引发地震和火山活动。
| Layer | State | Key feature |
|---|---|---|
| Crust | Solid | Thin, oceanic and continental |
| Mantle | Semi-solid | Convection currents |
| Outer core | Liquid | Iron and nickel, generates magnetic field |
| Inner core | Solid | Extremely hot, high pressure |
6. Plate Boundaries and Their Hazards | 板块边界及其灾害
There are three main types of plate boundary: constructive (plates move apart, magma rises to form new crust, e.g., Mid-Atlantic Ridge), destructive (plates collide, one sinks below the other, e.g., Pacific Ring of Fire), and conservative (plates slide past each other, e.g., San Andreas Fault).
板块边界主要有三种类型：建设型（板块分离，岩浆上升形成新地壳，如大西洋中脊）、破坏型（板块碰撞，一块俯冲到另一块下方，如环太平洋火山带）、保守型（板块相互滑动，如圣安德烈亚斯断层）。
At constructive boundaries, volcanic eruptions are common but often gentle; destructive boundaries produce violent volcanoes and deep earthquakes; conservative boundaries cause shallow, powerful earthquakes but no volcanoes.
建设型边界常有火山喷发，但往往较温和；破坏型边界产生猛烈火山和深层地震；保守型边界引发浅源强震，但无火山。
It is crucial to understand that people continue to live in hazard zones because of fertile volcanic soils, geothermal energy, tourism, and sometimes lack of alternative land.
要理解人们仍然居住在灾害多发区的原因：火山土壤肥沃、有地热能、旅游吸引力，有时也因缺乏替代土地。
7. Rivers: From Source to Mouth | 河流：从源头到河口
A river’s journey can be divided into three courses: upper course (steep, V-shaped valleys, vertical erosion), middle course (wider valley, lateral erosion, meanders), and lower course (wide floodplain, large meanders, oxbow lakes, deposition).
河流的旅程可分为三部分：上游（陡峭，V形谷，下切侵蚀为主）、中游（河谷变宽，侧蚀为主，曲流出现）、下游（宽阔泛滥平原，大型曲流，牛轭湖，沉积作用）。
The four processes of erosion are hydraulic action (force of water), abrasion (rocks scraping the bed and banks), attrition (rocks hitting each other and becoming smaller), and solution (chemical dissolving of rock). These shape the landscape through features such as waterfalls, gorges, and meanders.
四种侵蚀作用是：水力作用（水流的力量）、磨蚀（石块刮擦河床和河岸）、磨圆（石块相互撞击变小）、溶蚀（岩石化学溶解）。它们塑造出瀑布、峡谷和曲流等景观。
Deposition happens when a river loses energy and drops its load. This forms floodplains, levees, and deltas.
当河流能量减弱，搬运物沉积下来，便形成泛滥平原、天然堤和三角洲。
8. Coastal Processes and Landforms | 海岸过程与地貌
Waves are the main force shaping coastlines. Constructive waves have a strong swash and build up beaches; destructive waves have a strong backwash and erode the land.
波浪是塑造海岸线的主要力量。建设性海浪冲流强，堆积海滩；破坏性海浪回流强，侵蚀陆地。
Coastal erosion processes include hydraulic action, abrasion, attrition, and solution, similar to rivers. They create landforms such as headlands and bays, cliffs, wave-cut platforms, caves, arches, stacks, and stumps.
海岸侵蚀过程包括水力作用、磨蚀、磨圆和溶蚀，与河流相似。它们形成岬角与海湾、海蚀崖、海蚀平台、海蚀洞、海蚀拱、海蚀柱和残桩。
Longshore drift moves sediment along the coast in a zigzag pattern, leading to the formation of spits and bars. Understanding these processes helps explain why coastlines change over time.
沿岸漂流按锯齿形路径把沉积物沿海岸搬运，形成沙嘴和沙坝。理解这些过程有助于解释海岸线为何随时间变化。
9. Weather and Climate | 天气与气候
Weather refers to the short-term atmospheric conditions in a place — temperature, precipitation, wind, and cloud cover. Climate is the average weather of a place over at least 30 years. A helpful saying is: ‘Climate is what you expect, weather is what you get.’
天气指某地短期的大气状况——温度、降水、风力和云量。气候是某地至少 30 年的平均天气。有一句话很形象：“气候是你所预期的，天气是你所遇到的”。
The main climate zones are tropical (hot and wet), dry (arid, deserts), temperate (moderate temperatures and rainfall), continental (hot summers, cold winters), and polar (very cold, low precipitation). These zones occur because of latitude, altitude, distance from the sea, and prevailing winds.
主要气候带有：热带气候（高温多雨）、干燥气候（干旱、沙漠）、温带气候（温和的温度和降水）、大陆性气候（夏热冬冷）、极地气候（严寒、降水少）。这些气候带由纬度、海拔、距海远近和盛行风等因素决定。
10. Population Distribution and Density | 人口分布与密度
Population distribution describes where people live (scattered or clustered), while population density measures how many people live per square kilometre. Densely populated areas include coastal plains, river valleys, and cities; sparsely populated areas include deserts, high mountains, and dense rainforests.
人口分布描述人们居住在哪里（分散或集中），人口密度则衡量每平方公里居住多少人。人口稠密的地区包括沿海平原、河谷和城市；人口稀少的地区包括沙漠、高山和茂密雨林。
Factors encouraging high density: fertile soil, flat land, water supply, mild climate, and job opportunities. Factors discouraging settlement: extreme temperatures, steep slopes, poor soils, and lack of resources.
有利于高密度的因素：肥沃土壤、平坦地形、水源、温和气候和就业机会。不利于定居的因素：极端温度、陡峭山坡、贫瘠土壤和资源匮乏。
The world’s population is now over 8 billion, and it continues to grow, though at a slower rate. This growth places pressure on resources and the environment.
世界人口现已超过 80 亿，并继续增长，尽管增速放缓。这种增长给资源和环境带来压力。
11. Settlement Patterns and Functions | 聚落形态与功能
A settlement is a place where people live. The three main settlement patterns are dispersed (isolated houses), linear (along a road or river), and nucleated (clustered around a crossroad or water source).
聚落是人们居住的地方。三种主要聚落形态是：分散型（孤立房屋）、条带型（沿道路或河流分布）、集块型（围绕十字路口或水源聚集）。
Settlements also have functions: they can be market towns, ports, industrial centres, or dormitory suburbs. A settlement’s size and function often change over time, a process called urbanisation. In many parts of the world, megacities with over 10 million people are now common.
聚落还具有功能：可以是市镇、港口、工业中心或卧城郊区。聚落的规模和功能常随时间变化，这一过程称为城市化。在世界许多地方，人口超千万的超大城市已屡见不鲜。
The central business district (CBD) is the commercial heart of a city, often with tall buildings, high land values, and good transport links. Away from the centre, residential zones range from high-density inner-city housing to low-density suburbs on the edge.
中央商务区（CBD）是城市的商业核心，往往有高楼、高地价和优良的交通连接。远离市中心，住宅区从高密度的内城住房到低密度的郊区不等。
12. Development and Global Disparities | 发展与全球差异
Development is about improving the quality of life for people. It is measured not just by wealth (GDP per capita), but also by social indicators such as literacy rate, life expectancy, and access to clean water. The Human Development Index (HDI) combines these into a single score between 0 and 1.
发展关乎改善人们的生活质量。衡量发展不仅看财富（人均GDP），还看识字率、预期寿命和清洁水获取等社会指标。人类发展指数（HDI）把这些指标综合成一个 0 到 1 的得分。
There are huge differences between countries: high-income countries (HICs) generally have stable economies, good healthcare and education, while low-income countries (LICs) often struggle with poverty, disease, and limited infrastructure. Many newly emerging economies (NEEs) are industrialising rapidly.
国家间差异巨大：高收入国家（HICs）通常有稳定经济、良好医疗和教育，而低收入国家（LICs）常面临贫困、疾病和基础设施薄弱。许多新兴经济体（NEEs）正迅速工业化。
The north-south divide is a broad pattern where richer countries are mostly in the Northern Hemisphere, but this is a generalisation. Geography helps us understand why such disparities exist and how they can be reduced through fair trade and aid.
南北分化是一个大体模式，即富裕国家大多位于北半球，但这只是概括性说法。地理学帮助我们理解为何存在这种差异，以及如何通过公平贸易和援助来缩小差距。
