1. Test Overview and Command Words | 试卷概览与指令词

A typical Population and Settlement test lasts about 40 minutes and includes 5–6 questions worth a total of 25–30 marks. You will see resource-based questions using maps, graphs (like population pyramids) and photographs, alongside essay-style case-study questions. The key to success is understanding exactly what the command words ask you to do.

一份典型的人口与定居测试时长约40分钟，包含5–6道题，总分25–30分。你会遇到基于地图、图表（如人口金字塔）和照片的资料分析题，还有论文式的案例研究题。成功的关键在于准确理解指令词要求你做什么。

Command word 指令词	What it means 含义
Describe 描述	Say what you see – patterns, trends, locations. Do not give reasons. 说出你看到的内容——模式、趋势、位置。不解释原因。
Explain 解释	Give reasons ‘why’ or ‘how’, using linking words like ‘because’. 给出’为什么’或’如何’的原因，使用’因为’等连接词。
Compare 比较	Point out similarities and differences. 指出相似点和不同点。
Evaluate 评估	Make a judgement – weigh up strengths and weaknesses before you conclude. 做出判断——在得出结论前权衡优缺点。

2. Map Skills Question: Describing Population Distribution | 地图技能题：描述人口分布

Sample question: ‘Figure 1 shows population distribution in a region. Describe the distribution of population. (4 marks)’

样题：‘图1展示了一个地区的人口分布。描述人口分布。（4分）’

An effective answer always starts with an overall statement, then adds specific detail using compass directions and map evidence. For example: “Overall, the population is concentrated along the south-west coast and in the river valleys, while the north-east highlands are sparsely populated. For instance, there is a dense cluster of settlement symbols around the estuary of River X, whereas the inland plateau shown in the north-east has very few symbols. There is also a clear pattern of decreasing density with increasing altitude and distance from the coast.”

有效的答案总是以总体陈述开头，然后用方位词和地图证据补充具体细节。例如：”总体而言，人口集中在西南海岸和河谷地区，而东北部高地人口稀少。例如，在X河河口附近有密集的聚落符号，而东北部的内陆高原符号很少。还有一个明显的模式是随着海拔升高和距海岸距离增加，密度递减。”

Marking tips: Use geographical vocabulary (dense, sparse, linear, nucleated), refer to named places on the map, and always mention an overall pattern. Do not just list places without linking them to the bigger picture.

评分提示：使用地理词汇（密集、稀疏、线状、团状），提及地图上的指定地点，并始终提及总体模式。不要只是罗列地点而不联系全局。

3. Calculating and Explaining Population Density | 计算并解释人口密度

Calculation question: ‘Region Y has a population of 500,000 and an area of 250 km². Calculate the population density. (2 marks)’

计算题：‘地区Y人口为500,000，面积为250 km²。计算人口密度。（2分）’

Population Density = Population ÷ Area

Step 1: Recall the formula. Step 2: Substitute the numbers: 500,000 ÷ 250 = 2000 people per km². Always include the correct units – forgetting them can lose you a mark.

第1步：回忆公式。第2步：代入数字：500,000 ÷ 250 = 每平方千米2000人。务必写上正确的单位——遗漏单位会失分。

Explain question: ‘Suggest reasons why some areas have a high population density. (4 marks)’

解释题：‘给出一些地区人口密度高的原因。（4分）’

You need to separate your answer into physical and human factors. For physical reasons, mention flat relief (easy to build on), fertile soils (good for farming), reliable water supply (rivers, lakes), and a mild climate. For human reasons, talk about economic opportunities (many jobs in cities), good transport links (ports, roads), and historical settlement (ancient cities). Always link the factor to population – for example, ‘Flat land makes it easier to construct houses and infrastructure, so more people can live there.’

你需要将答案分为自然因素和人文因素。自然因素方面，提及平坦的地形（易于建设）、肥沃的土壤（适宜农耕）、可靠的水源（河流、湖泊）和温和的气候。人文因素方面，谈及经济机会（城市就业岗位多）、良好的交通连接（港口、公路）和历史定居（古城）。始终将因素与人口联系起来——例如，’平坦的土地使得建造房屋和基础设施更容易，因此更多人能居住在那里。’

4. Interpreting a Population Pyramid | 解读人口金字塔

Figure 2 shows a population pyramid for Country A. It has a very wide base that narrows quickly as you go up, with only a tiny top bar. Question: ‘Describe the shape of the pyramid and suggest what population challenges Country A may face in the future. (6 marks)’

图2显示A国的人口金字塔。它的底部非常宽，向上迅速变窄，顶部只有极细的横条。问题：‘描述该金字塔的形状，并推断A国未来可能面临的人口挑战。（6分）’

Model description: ‘The pyramid has a concave shape with a wide base, indicating a very high birth rate. It narrows sharply in the older age groups, which shows a relatively high death rate among adults, leading to a low life expectancy. This is typical of an expansive (Stage 1 or early Stage 2) population structure.’

示例描述：‘这个金字塔呈凹形，底部宽大，表明出生率非常高。随着年龄组上升，金字塔急剧变窄，显示成年人死亡率相对较高，导致预期寿命低。这是扩张型（第1阶段或早期第2阶段）人口结构的典型特征。’

Future challenges: With a large proportion of young dependents, Country A will need to invest heavily in schools, childcare and healthcare. In the medium term, it must create enough jobs to prevent high youth unemployment. Rapid population growth could put pressure on food, water and housing, potentially leading to overpopulation if resources are not managed well.

未来挑战：由于年轻依赖人口比例大，A国需要大量投资于学校、儿童保育和医疗。中期来看，必须创造足够就业以防止高青年失业率。快速的人口增长可能给食物、水和住房带来压力，若资源管理不善，可能导致人口过剩。

5. Case Study: High Population Density in Bangladesh | 案例分析：孟加拉国的高人口密度

Question: ‘Using a named location, explain why some low-lying delta regions have very high population densities. (6 marks)’

问题：‘以某一个地点为例，解释为何一些低洼三角洲地区人口密度极高。（6分）’

Named case study: Bangladesh (Ganges–Brahmaputra Delta).

指定案例：孟加拉国（恒河-布拉马普特拉河三角洲）。

Physical reasons: The delta is formed by huge rivers depositing fertile alluvial soil, which is ideal for rice cultivation. The flat terrain makes it easy to build homes and roads. Abundant monsoon rainfall and a dense river network provide water for irrigation and domestic use. The warm climate allows year-round farming, supporting a large population.

自然原因：该三角洲由巨大河流沉积肥沃的冲积土形成，非常适合水稻种植。平坦的地形便于建造房屋和道路。丰富的季风降雨和密集的水网为灌溉及生活提供了水源。温暖的气候允许全年耕种，支撑大量人口。

Human reasons: Agriculture has been the main livelihood for centuries, resulting in deep historical roots. Rivers have traditionally provided cheap transport for trade, attracting traders and settlers. The capital city Dhaka offers employment in the garment industry, pulling in migrants. Despite natural hazards like flooding, the perceived economic opportunities keep the density extremely high – over 1,200 people per km².

人文原因：几个世纪以来农业一直是主要生计，形成了深厚的历史根基。河流传统上为贸易提供了廉价运输，吸引商人和定居者。首都达卡提供服装业就业机会，吸引移民涌入。尽管有洪水等自然灾害，但人们感知到的经济机会仍使人口密度极高——超过每平方千米1200人。
