1. Compass Directions and Bearings | 指南针方向与方位角

Question 1: Give the three-figure bearing for each compass direction: North, Northeast, Southwest. (3 marks)

第1题： 写出以下各指南针方向的三位方位角：北、东北、西南。（3分）

Bearings are always measured clockwise from north, with north being 000° (or 360°). Northeast is exactly halfway between north and east, giving a bearing of 045°. Southwest is halfway between south and west, which is 225°. It is essential to use three figures, so north must be written as 000°, not 0°.

方位角总是从北顺时针方向测量，北为 000°（或 360°）。东北正好位于北与东的中间，方位角为 045°。西南位于南与西的中间，方位角为 225°。必须使用三位数字表示，因此北必须写成 000°，而非 0°。

Compass Direction	Bearing
North	000°
Northeast	045°
Southwest	225°

A common mistake is to confuse east and west or to forget the three-figure format. Always imagine a compass rose with 360 degrees and count clockwise.

常见的错误是混淆东和西，或者忘记三位数的格式。想象一个 360 度的罗盘花，始终顺时针计数。

2. Map Scales and Distance Calculation | 地图比例尺与距离计算

Question 2: On a map with a scale of 1:50 000, the distance between two villages is 4 cm. Calculate the actual ground distance in kilometres. (2 marks)

第2题： 在一幅比例尺为 1:50 000 的地图上，两个村庄之间的图上距离是 4 cm。计算实际地面距离，以公里为单位。（2分）

The scale 1:50 000 means that 1 cm on the map represents 50 000 cm on the ground. Multiply the measured distance by the scale: 4 cm × 50 000 = 200 000 cm. To convert centimetres to kilometres, divide by 100 000 (since 1 km = 100 000 cm). Therefore, 200 000 cm ÷ 100 000 = 2 km. The actual distance is 2 kilometres.

比例尺 1:50 000 表示地图上 1 厘米代表实地 50 000 厘米。用测量的距离乘以比例尺：4 cm × 50 000 = 200 000 cm。要将厘米转换为公里，除以 100 000（因为 1 公里 = 100 000 厘米）。因此，200 000 cm ÷ 100 000 = 2 km。实际距离为 2 公里。

Always write the unit in the final answer, and show your working. An alternative method is to convert the scale to km first: 50 000 cm = 0.5 km per cm, then 4 × 0.5 = 2 km.

最终答案务必写明单位，并写出计算过程。另一种方法是先将比例尺转换为公里：50 000 cm = 0.5 km/cm，然后 4 × 0.5 = 2 km。

3. Interpreting Contour Lines | 解读等高线

Question 3: If contour lines on a map are very close together, what does this tell you about the landscape? (2 marks)

第3题： 如果地图上的等高线非常靠近，这告诉你关于地形有什么信息？（2分）

Closely spaced contour lines indicate a steep slope. Each contour line joins points of equal height, so when lines are packed together, there is a rapid change in elevation over a short horizontal distance. Conversely, widely spaced contours show a gentle slope or flat land. Remember that contour lines never cross each other and that the closer they are, the steeper the terrain.

密集的等高线表示陡坡。每条等高线连接的是高度相同的点，因此当线条紧靠在一起时，说明在短距离内海拔变化迅速。相反，稀疏的等高线表示缓坡或平地。请记住，等高线永不相交，线越密地势越陡。

This skill is often tested with a topographic map extract. You might also be asked to identify a hilltop, a valley or a ridge using contour patterns.

这项技能常通过地形图片段进行考查。还可能会要求你利用等高线形态识别山顶、山谷或山脊。

4. Layers of the Earth | 地球的圈层

Question 4: Label the diagram of the Earth’s interior with these terms: crust, mantle, outer core, inner core. (4 marks)

第4题： 用以下术语标注地球内部结构图：地壳、地幔、外核、内核。（4分）

The correct order from the surface to the centre is: crust, mantle, outer core, inner core. The crust is the thinnest layer, made of solid rock. The mantle is thick, semi-solid rock that flows slowly. The outer core is liquid iron and nickel, and the inner core is solid because of immense pressure despite extremely high temperatures.

从表面到中心的正确顺序是：地壳、地幔、外核、内核。地壳是最薄的一层，由固体岩石组成。地幔是厚层的半固态岩石，缓慢流动。外核是液态的铁和镍，内核由于承受巨大压力呈固态，尽管温度极高。

Knowing the state of each layer helps explain tectonic plate movement: the lithosphere (crust and upper mantle) floats on the semifluid asthenosphere.

了解各层的状态有助于解释板块构造运动：岩石圈（地壳和上地幔）漂浮在半流体的软流圈之上。

5. Population Density Calculation | 人口密度计算

Question 5: A small island has a population of 2,000 people and an area of 5 km². Calculate its population density. (2 marks)

第5题： 一个小岛上有人口 2,000 人，面积 5 平方千米。计算其人口密度。（2分）

Population density is calculated as total population divided by total area. Density = 2,000 ÷ 5 = 400 people per km². Always include the unit ‘people per km²’ or ‘inhabitants/km²’. This formula can also be used to compare how crowded different regions are.

人口密度的计算方法是总人口除以总面积。密度 = 2,000 ÷ 5 = 400 人/平方千米。务必带上单位“人/平方千米”。该公式也可用于比较不同地区的拥挤程度。

If the question provides population and density, you can rearrange to find area: Area = Population ÷ Density. Understanding this relationship is crucial for geographical analysis.

如果题目给出人口和密度，你可以通过变形求出面积：面积 = 人口 ÷ 密度。理解这一关系对地理分析至关重要。

6. Settlement Patterns | 定居点模式

Question 6: Describe the settlement pattern shown in Figure 1 (a row of houses along a road). (2 marks)

第6题： 描述图 1 中显示的定居点模式（沿道路的一排房屋）。（2分）

The pattern is linear settlement. Houses are arranged in a line along a transport route such as a road or river. Other common patterns include nucleated (clustered around a central point) and dispersed (houses spread widely apart). A linear pattern often develops because access to the route is economically important.

该模式是线性定居。房屋沿着道路或河流等交通路线呈线状排列。其他常见模式包括集聚型（围绕一个中心点聚集）和分散型（房屋相距很远）。线性模式常因交通路线的经济重要性而形成。

In your answer, use key geographical terms and support them with evidence from the figure. Just writing ‘houses along a road’ earns some marks, but naming the pattern earns full marks.

作答时，请使用关键地理术语，并结合图中的证据。只写“房屋沿路分布”能得部分分数，但说出模式名称才能得满分。

7. Reading a Thermometer | 读取温度计

Question 7: What is the temperature shown by the mercury in the diagram? (1 mark)

第7题： 图中水银柱显示的温度是多少？（1分）

Assuming the diagram shows the mercury at -5 °C, you must read the scale carefully, noting whether readings are above or below zero. The liquid’s top should be read at eye level to avoid parallax error. In a standard liquid-in-glass thermometer, each small division often represents 1 °C. Always include the minus sign for temperatures below freezing.

假设图中显示水银柱在 -5 °C，你必须仔细阅读刻度，注意读数是零上还是零下。应在与液面顶端齐平的位置读数，以避免视差错误。在标准的玻璃液体温度计中，每个小刻度通常表示 1 °C。低于冰点的温度务必加上负号。

Temperature recording is a basic meteorological skill, often used when interpreting climate graphs or weather station data.

温度记录是一项基本的气象技能，在解读气候图表或气象站数据时经常用到。

8. River Features – Meanders | 河流特征 – 曲流

Question 8: Explain how a meander forms. (4 marks)

第8题： 解释曲流是如何形成的。（4分）

A meander forms in the middle and lower course of a river where the gradient is gentle. Water flows faster on the outside of a slight bend, causing erosion (often by corrasion and hydraulic action), while on the inside the river flows slower, leading to deposition of sediment. Over time, the bend becomes more pronounced, creating a looping meander. The outer bank forms a river cliff, and the inner bank builds up a slip-off slope.

曲流形成在河流的中下游，坡度平缓处。在略微弯曲处，外侧水流速度较快，造成侵蚀（常通过磨蚀和水力作用），而内侧水流较慢，导致泥沙沉积。随着时间的推移，弯道变得更加明显，形成蜿蜒的曲流。外岸形成河蚀崖，内岸则堆积成滑走坡。

If the meander becomes so pronounced that the river cuts through the neck during high flow, an oxbow lake may be formed. This demonstrates the dynamic nature of fluvial landscapes.

如果曲流变得过于弯曲，河流在高流量时截断曲流颈，就可能形成牛轭湖。这展示了河流地貌的动态特性。

9. Volcanoes: Positive and Negative Impacts | 火山的正面与负面影响

Question 9: Give one positive and one negative effect of a volcanic eruption. (2 marks)

第9题： 举出火山喷发的一个正面影响和一个负面影响。（2分）

One positive effect is that volcanic ash enriches soil with minerals, making it very fertile for farming (e.g., around Mount Etna). Another positive is geothermal energy used for heating. A negative effect is the destruction of houses and infrastructure by lava flows and pyroclastic surges, which can cause loss of life. Volcanic ash can also disrupt flights and damage crops.

一个正面影响是火山灰富含矿物质，使土壤变得肥沃，有利于农业（如埃特纳火山周边地区）。另一个正面影响是可利用地热能供暖。负面影响是熔岩流和火山碎屑涌浪毁坏房屋与基础设施，可能导致人员伤亡。火山灰还会干扰航班并毁坏庄稼。

Make sure your answer includes a specific example or clear explanation to gain full marks. Avoid vague statements like ‘it is dangerous’.

确保你的答案包含具体例子或清晰解释，以获得满分。避免使用“它很危险”这类笼统的表述。

10. The 3 Rs of Waste Management | 废物管理的3R原则

Question 10: Name the three Rs and give one example of each. (3 marks)

第10题： 说出三个R，并分别举出一个例子。（3分）

The three Rs are Reduce, Reuse and Recycle. Reduce means using fewer resources, for example, taking a reusable bag to the shop instead of buying plastic ones. Reuse involves using an item again for the same or a different purpose, such as refilling a glass bottle. Recycle means processing waste materials into new products, like melting old aluminium cans to make new ones.

三个R 是减量(Reduce)、重复使用(Reuse)和回收(Recycle)。减量意味着使用更少的资源，例如，自带可重复使用的袋子去商店，而不购买塑料袋。重复使用指将物品再次用于相同或不同目的，如再次使用玻璃瓶。回收指将废料处理后制成新产品，比如熔化旧铝罐来制造新罐子。

These strategies reduce the amount of waste sent to landfill and lower the demand for raw materials, helping to manage environmental sustainability.

这些策略减少了送往填埋场的垃圾量，并降低了对原材料的需求，有助于管理环境的可持续发展。
