1. Map Skills and Grid References | 地图技能与网格参考

Four-figure grid references locate a grid square on an Ordnance Survey map. The first two numbers refer to the easting (along the bottom), and the last two refer to the northing (up the side). Remember the phrase ‘along the corridor and up the stairs’.

四位网格参考用于在全国地形测量图上定位一个网格方格。前两个数字表示东向坐标值（沿底部水平方向），后两个数字表示北向坐标值（沿侧边垂直方向）。记住口诀“先横后纵”。

Six-figure grid references pinpoint an exact location within a grid square. You divide the square into ten imaginary lines along and up, then add a third digit to the easting and northing. This gives a much more precise position for features such as a church or a bridge.

六位网格参考可以精确定位网格方格内的具体位置。你将方格沿水平和垂直方向各划分为十等分，然后在东向和北向坐标后分别加上第三位数字。这样就能更精准地确定教堂、桥梁等特征的位置。

Scale shows the relationship between distance on the map and distance on the ground. A scale of 1:25 000 means 1 cm on the map represents 25 000 cm (250 m) on the ground. You can measure straight-line distances using a ruler and curved distances with a piece of string or a map measurer.

比例尺表示地图上的距离与地面实际距离的关系。1:25 000 的比例尺意味着地图上 1 厘米代表实地 250 米（25 000 厘米）。你可以用直尺测量直线距离，用细绳或地图量测器测量曲线距离。

Contour lines connect points of equal height and show the shape and steepness of the land. Closely spaced contours indicate a steep slope, while widely spaced contours show a gentle slope. Spot heights and triangulation pillars give exact altitudes.

等高线连接高度相同的点，显示地形的形状和坡度。等高线密集表示陡坡，稀疏则表示缓坡。点高程和三角测量柱提供确切的海拔高度。

2. Weather and Climate | 天气与气候

Weather describes the day-to-day condition of the atmosphere – including temperature, precipitation, wind speed and cloud cover. Climate is the average weather of a place over a long period, usually 30 years. The UK has a temperate maritime climate, with mild, wet winters and cool, changeable summers.

天气描述大气的日常状况，包括气温、降水、风速和云量。气候是一个地方在较长时期（通常为30年）内的平均天气状况。英国属于温带海洋性气候，冬季温和多雨，夏季凉爽多变。

Several factors influence the UK’s weather: air masses (polar maritime and tropical maritime), the prevailing south-westerly winds, the North Atlantic Drift (a warm ocean current), and depressions (low-pressure systems) that bring rain and wind.

影响英国天气的因素有多方面：气团（极地海洋气团和热带海洋气团）、盛行的西南风、北大西洋暖流（一股温暖洋流）以及带来降雨和强风的低气压系统（气旋）。

Weather instruments are used to collect data: a thermometer measures temperature, a rain gauge measures precipitation, an anemometer measures wind speed, and a barometer measures air pressure. Weather maps use symbols and isobars to show pressure systems and fronts.

天气仪器用于采集数据：温度计测气温，雨量计测降水，风速计测风速，气压计测气压。天气图使用符号和等压线来显示气压系统和锋面。

3. River Processes and Landforms | 河流过程与地貌

A river’s drainage basin is the area of land drained by a river and its tributaries. The boundary between basins is called the watershed. Rivers erode their channels through hydraulic action, abrasion, attrition and solution. They transport material by traction, saltation, suspension and solution.

河流的流域是指一条河流及其支流排水的陆地区域。流域之间的分界线称为分水岭。河流通过水力作用、磨蚀、磨耗和溶蚀来侵蚀河床。它们通过推移、跃移、悬移和溶解方式来搬运物质。

In the upper course, steep gradients create v-shaped valleys, interlocking spurs and waterfalls. A waterfall forms where hard rock lies over soft rock; the soft rock is eroded faster, creating a step and a plunge pool. In the middle course, meanders develop as the river erodes the outside bank and deposits on the inside.

在上游，陡峭的坡降形成 V 形谷、交错山嘴和瀑布。瀑布形成于硬岩层覆盖在软岩层之上的地方；软岩被更快侵蚀，形成阶梯和瀑潭。中游河段，河流侵蚀凹岸并在凸岸沉积，形成曲流。

In the lower course, floodplains and levees are built up by repeated flooding. An oxbow lake forms when a meander is cut off from the main channel. Flooding can be managed using dams, embankments and flood-warning systems.

下游河段，洪泛和自然堤由反复泛滥堆积而成。当曲流被截弯取直后，形成牛轭湖。洪水可通过水坝、堤防和洪水预警系统进行管理。

4. Coastal Processes and Landforms | 海岸过程与地貌

Waves are the main agent of coastal erosion. Destructive waves have a strong backwash that removes material, while constructive waves have a strong swash that deposits sediment. Erosion processes include hydraulic action, abrasion, attrition and solution, similar to rivers.

波浪是海岸侵蚀的主要动力。破坏性波浪具有强烈的回流，会搬走物质；而建设性波浪具有强烈的上冲流，会堆积沉积物。侵蚀过程包括水力作用、磨蚀、磨耗和溶蚀，与河流类似。

Erosional landforms include headlands and bays, which form where bands of hard and soft rock alternate. Caves, arches and stacks are created when waves attack weaknesses in a headland. Longshore drift moves sediment along a beach, leading to the formation of spits and bars.

侵蚀地貌包括岬角和海湾，形成于软硬岩层交替的地带。波浪侵蚀岬角的薄弱部位，依次形成洞穴、拱门和海蚀柱。沿岸漂移沿沙滩输送沉积物，导致沙嘴和沙坝的形成。

Coastal management uses both hard engineering (sea walls, groynes, rock armour) and soft engineering (beach nourishment, managed retreat) to protect the coast from erosion and flooding. Each method has advantages and disadvantages in terms of cost and environmental impact.

海岸管理采用硬工程（海堤、丁坝、抛石护岸）和软工程（海滩补沙、有管理地撤退）来保护海岸免受侵蚀和洪水侵袭。每种方法在成本和环境影响方面都有利有弊。

5. Population and Migration | 人口与迁移

Population distribution describes where people live; it is uneven across the world due to factors such as climate, relief, water supply and economic opportunities. Population density is the number of people per square kilometre. Densely populated areas often have fertile land and good transport links.

人口分布描述人口居住的地点；由于气候、地形、水源和经济机会等因素，世界各地人口分布不均。人口密度是指每平方公里的人口数量。人口稠密地区通常拥有肥沃的土地和良好的交通网络。

Population pyramids show the age and sex structure of a population. A wide base suggests a high birth rate, typical of a developing country. A narrow base and wider top indicate an ageing population, common in developed countries. This helps planners predict future needs for schools and healthcare.

人口金字塔显示人口的年龄和性别结构。底部宽大表示高出生率，是发展中国家的典型特征。底部窄、上部较宽表示人口老龄化，常见于发达国家。这有助于规划者预测未来对学校及医疗保健的需求。

Migration is the movement of people from one place to another. Push factors (e.g. unemployment, war, natural disasters) drive people away, while pull factors (e.g. job opportunities, safety, better services) attract them. Migration has impacts on both the source and host regions, including economic and cultural changes.

迁移是指人们从一个地方移动到另一个地方。推力因素（如失业、战争、自然灾害）驱使他们离开，拉力因素（如就业机会、安全、更好的服务）则吸引他们。迁移对来源地和接收地都会产生影响，包括经济和文化变化。

6. Settlement Patterns and Urbanisation | 聚落模式与城市化

A settlement is a place where people live. Their pattern can be dispersed, nucleated or linear, often influenced by physical factors like water supply, fertile soil and defence. The function of a settlement can change over time – for example, a market town may become a commuter settlement.

聚落是人们居住的地方。其分布模式可以是分散型、集聚型或线型，通常受水源、肥沃土壤和防御等自然因素影响。聚落的功能会随时间变化，例如一个集镇可能演变为通勤居住地。

Urbanisation is the growth in the proportion of a country’s population living in towns and cities. It is caused by rural-to-urban migration and natural increase. Cities in developing countries are growing rapidly, leading to the expansion of informal settlements with poor sanitation and overcrowding.

城市化是指一个国家居住在城市和城镇的人口比例增长。其原因包括农村向城市迁移和自然增长。发展中国家城市正快速扩张，导致缺乏卫生设施的拥挤非正式住区蔓延。

Urban land use models, such as the Burgess and Hoyt models, show how cities are organised into zones. The Central Business District (CBD) is at the heart, surrounded by inner city industry and terraced housing, then outer suburbs with larger houses, and finally the rural-urban fringe with retail parks and farmland.

城市土地利用模型，如伯吉斯模型和霍伊特模型，展示了城市如何划分为不同区域。中央商务区（CBD）位于核心，周围是内城工业区和连排房屋，然后是拥有较大住宅的郊区，最后是城乡结合部，分布着零售园区和农田。

7. Economic Activities and Resources | 经济活动与资源

Economic activities are classified into primary (extracting raw materials, e.g. farming, fishing, mining), secondary (manufacturing, e.g. car assembly, food processing) and tertiary (providing services, e.g. retail, education, tourism). De-industrialisation in the UK has seen a decline in primary and secondary jobs and a rise in tertiary employment.

经济活动分为第一产业（开采原材料，如农业、渔业、采矿）、第二产业（制造业，如汽车装配、食品加工）和第三产业（提供服务，如零售、教育、旅游）。英国的去工业化已导致第一和第二产业岗位减少，第三产业就业上升。

Resources can be non-renewable (finite, such as coal, oil and natural gas) or renewable (infinite in human timescale, such as solar, wind and hydroelectric power). Using renewable energy reduces greenhouse gas emissions and helps tackle climate change, although some schemes can have local environmental impacts.

资源可以是非可再生资源（数量有限，如煤、石油和天然气），也可以是可再生资源（在人类时间尺度上无穷尽，如太阳能、风能和水力发电）。使用可再生能源能减少温室气体排放，有助于应对气候变化，尽管某些项目会对当地环境造成影响。

Globalisation has increased trade and the movement of goods, ideas and capital. Transnational corporations (TNCs) operate in many countries, often manufacturing in lower-cost locations. This can bring jobs and investment but can also lead to exploitation and environmental damage if not regulated.

全球化促进了贸易以及商品、思想和资本的流动。跨国公司在多个国家运营，通常在成本较低的地点进行制造。这可以带来就业和投资，但若不加管控，也可能导致剥削和环境破坏。

8. Climate Change: Causes and Impacts | 气候变化：原因与影响

The greenhouse effect is a natural process where gases such as carbon dioxide and methane trap heat in the atmosphere, keeping the Earth warm enough for life. However, human activities – burning fossil fuels, deforestation and agriculture – have increased the concentration of these gases, enhancing the effect and leading to global warming.

温室效应是一个自然过程，二氧化碳、甲烷等气体将热量留在大气层中，使地球保持适合生命生存的温度。然而，人类活动——燃烧化石燃料、砍伐森林和农业生产——增加了这些气体的浓度，增强了温室效应，导致全球变暖。

Evidence of climate change includes rising global temperatures, melting ice caps and glaciers, rising sea levels and more frequent extreme weather events such as heatwaves, droughts and intense storms. Ice cores and tree rings provide long-term climate data.

气候变化的证据包括全球气温上升、冰盖和冰川融化、海平面升高，以及热浪、干旱和强风暴等极端天气事件更加频繁。冰芯和树木年轮提供了长期气候数据。

Impacts of climate change are felt differently around the world. Low-lying countries face coastal flooding, arid regions may experience desertification, and agriculture could be disrupted by changing rainfall patterns. Mitigation strategies include switching to renewable energy, improving public transport and reforestation.

气候变化对世界各地的影响各不相同。低洼国家面临沿海洪水，干旱地区可能经历荒漠化，农业可能因降雨模式改变而遭受破坏。缓解策略包括转而使用可再生能源、改善公共交通和植树造林。

9. Natural Hazards: Tectonic and Atmospheric | 自然灾害：地质与气象灾害

Tectonic hazards include earthquakes and volcanic eruptions, which occur mainly at plate boundaries. At destructive boundaries, an oceanic plate subducts under a continental plate, causing powerful earthquakes and explosive volcanoes. At constructive boundaries, plates move apart and magma rises, forming gentler volcanic eruptions.

地质构造灾害包括地震和火山喷发，主要发生在板块边界。在破坏性边界，海洋板块俯冲到大陆板块之下，引发强烈地震和爆发式火山。在建设性边界，板块分离，岩浆上升，形成较温和的火山喷发。

The effects of an earthquake depend on its magnitude, depth, distance from the epicentre and the level of preparedness. Building designs, such as shock absorbers in foundations and reinforced structures, can reduce damage. Emergency supplies and evacuation plans are essential in high-risk zones.

地震的影响取决于震级、震源深度、距震中的距离以及备灾水平。建筑设计，如地基减震器和加固结构，可以减少损害。应急物资和疏散计划在高风险地区至关重要。

Tropical storms, also called hurricanes, cyclones or typhoons, form over warm oceans (above 27 °C). They bring high winds, torrential rain and storm surges. Monitoring and early-warning systems, along with community education, help reduce loss of life.

热带风暴（也称飓风、气旋或台风）在温暖的海洋（超过 27 °C）上空形成。它们会带来强风、暴雨和风暴潮。监测和预警系统以及社区教育有助于减少人员伤亡。

10. Sustainable Development and Conservation | 可持续发展与保护

Sustainable development means meeting the needs of the present without compromising the ability of future generations to meet their own needs. It balances three pillars: economic growth, social equity and environmental protection. Eco-tourism and sustainable farming are practical examples.

可持续发展意味着既满足当代人的需求，又不损害后代人满足其自身需求的能力。它平衡了三大支柱：经济增长、社会公平和环境保护。生态旅游和可持续农业是实际的应用实例。

Conservation protects ecosystems and biodiversity. National parks, such as the Mourne Mountains in Northern Ireland, aim to preserve landscapes and habitats while allowing responsible recreation. Conflicts can arise between conservationists and developers who want to build new housing or infrastructure.

保护措施能保护生态系统和生物多样性。国家公园，如北爱尔兰的莫恩山，旨在保护景观和栖息地，同时允许负责任的休闲活动。自然保护者与希望建设新住房或基础设施的开发商之间可能出现冲突。

Local action is also important. Recycling, reducing food waste, using less water and supporting local produce are small changes that can collectively lower our ecological footprint. Understanding our interdependence with the natural world is central to KS3 Geography.

地方层面的行动也很重要。回收利用、减少食物浪费、节约用水和支持本地产品都是能够共同减少我们生态足迹的小改变。认识我们与自然世界的相互依赖是 KS3 地理的核心。
