📚 IGCSE WJEC Geography: Interdisciplinary Integrated Question Training | IGCSE WJEC 地理：跨学科综合题型训练
WJEC IGCSE Geography often combines physical and human themes with numeracy, graph interpretation, map skills and decision-making. This article trains you to handle cross-topic questions by linking geographical knowledge, source analysis and data skills under exam conditions.
WJEC IGCSE 地理常将自然与人文主题同数字运算、图表判读、地图技能和决策分析结合起来。本文通过串联地理知识、资料分析与数据技能，帮助你在考试条件下应对跨主题综合题。
1. What Makes a WJEC Geography Question Interdisciplinary? | 什么是 WJEC 地理跨学科综合题？
WJEC examination papers reward candidates who can combine knowledge from two or more geography topics. A single question may present a photograph, a graph and a map extract, then ask you to explain causes, assess impacts and justify a management option. This is interdisciplinary because it tests geographical understanding, source interpretation and numeracy at the same time.
WJEC 试卷鼓励考生综合两个或多个地理主题的知识。一道题可能同时给出照片、图表和地图片段，要求解释成因、评价影响并论证管理方案。这类题之所以是跨学科的，是因为它同时考查地理理解、资料判读和数字运算能力。
Typical command words include 'describe', 'explain', 'compare', 'evaluate' and 'justify'. In integrated questions, 'to what extent' or 'assess' usually requires a balanced argument using evidence from the resource booklet, not just a list of facts.
常见指令词包括 describe（描述）、explain（解释）、compare（比较）、evaluate（评价）和 justify（论证）。在综合题中，to what extent（在多大程度上）或 assess（评估）通常要求利用资源手册中的证据进行正反论证，而不仅仅是罗列事实。
| Command word | English meaning | 中文含义 |
|---|---|---|
| Describe | Say what you see or what happens | 描述所见或所发生的情况 |
| Explain | Give reasons or causes | 给出原因或成因 |
| Evaluate | Consider strengths and weaknesses, then judge | 分析优缺点并作出判断 |
| Justify | Support a choice with evidence | 用证据支持某一选择 |
2. Numeracy in Geography: Ratio, Percentage and Rate | 地理中的数字技能：比、百分比与速率
Many WJEC questions require you to calculate percentages, ratios or rates. You must be confident with units such as people per km², metres per year, millimetres per hour and cubic metres per second. Always show working because method marks are often available even if the final answer is wrong.
许多 WJEC 题目要求计算百分比、比率或速率。你必须熟悉人/平方千米、米/年、毫米/小时和立方米/秒等单位。作答时务必写出计算过程，因为即使最终答案错误，通常也能获得方法分。
Percentage change = ((new value - original value) ÷ original value) × 100
Population density = total population ÷ area (people per km²)
12,000 to 15,600 people, the percentage change is ((15,600 - 12,000) ÷ 12,000) × 100 = 30% the urban area is 8 km², the new population density is 15,600 ÷ 8 = 1,950 people per km².
例如，某城镇人口从 12,000 人增至 15,600 人，变化率为 ((15,600 - 12,000) ÷ 12,000) × 100 = 30%。若城镇面积为 8 平方千米，则新人口密度为 15,600 ÷ 8 = 1,950 人/平方千米。
| Measure | Formula | Common use |
|---|---|---|
| Population density | Total population ÷ area | Comparing crowded and sparse areas |
| Percentage change | ((new - old) ÷ old) × 100 | Population growth, GDP change |
| Rate of erosion | Distance lost ÷ time period | Coastal retreat in metres per year |
3. Graph Skills: Climate Graphs and Hydrographs | 图表技能：气候图与水文过程线
Climate graphs combine monthly average temperature as a line and monthly precipitation as bars. You should read values accurately, identify seasonal patterns and relate them to latitude, altitude, distance from the sea, ocean currents and prevailing winds.
气候图以折线表示月平均气温，以柱状表示月降水量。你需要准确读取数值、识别季节变化，并将其与纬度、海拔、距海远近、洋流和盛行风联系起来。
A flood hydrograph shows river discharge over time. Key features include the rising limb, peak discharge, falling limb and lag time. A short lag time suggests rapid surface runoff, often caused by urban surfaces, steep slopes, saturated soil or limited vegetation cover.
洪水过程线显示河流流量随时间的变化。关键特征包括涨水段、洪峰流量、退水段和滞时。滞时短说明地表径流快，通常由城市地表、陡坡、土壤饱和或植被覆盖少引起。
| Feature | English meaning | 中文含义 |
|---|---|---|
| Rising limb | Rising part of the graph showing increasing discharge | 涨水段：流量上升的部分 |
| Peak discharge | Highest flow reached | 洪峰流量：达到的最高流量 |
| Lag time | Delay between peak rainfall and peak discharge | 滞时：降雨峰值与流量峰值之间的延迟 |
When interpreting a hydrograph, compare the shape before and after urbanisation or deforestation. For example, after urban growth the line usually rises more steeply, peaks higher and falls faster, increasing flood risk downstream.
判读水文过程线时，应比较城市化或森林砍伐前后的曲线形状。例如，城市扩张后曲线通常上升更陡、峰值更高、退水更快，从而加大下游洪涝风险。
4. Map Skills: Scale, Distance and Bearings | 地图技能：比例尺、距离与方位角
Ordnance Survey-style maps appear in WJEC papers. You need four-figure and six-figure grid references, scale conversion, distance measurement and direction using compass bearings. Contour patterns help you describe relief, gradient and river valleys.
WJEC 试卷中常出现类似英国地形测量局的地图。你需要掌握四位和六位坐标、比例尺换算、距离量算和罗盘方位角。等高线形态有助于描述地形起伏、坡度和河谷。
Real distance (cm) = map distance (cm) × scale factor
m = 100,000 cm = 1,000 m = 1 km in reality. For a 1:50,000 map, the same 4 cm equals 2 km.
在 1:25,000 地图上，图上 4 厘米等于 4 × 25,000 厘米 = 100,000 厘米 = 1,000 米 = 1 千米。在 1:50,000 地图上，同样的 4 厘米等于 2 千米。
When measuring a winding route, mark small straight sections along the paper edge, then total them against the scale bar. For bearings, measure clockwise from grid north using a protractor. Always quote three-figure bearings, such as 045° rather than 45°.
量测弯曲路线时，可沿纸边分段标记直线段，再对照比例尺求和。方位角需从网格北起顺时针用量角器量取。方位角必须写成三位数，例如 045° 而不是 45°。
5. Population Pyramids and Demographic Transition | 人口金字塔与人口转变模型
Population pyramids show age and sex structure. A wide base indicates a high birth rate, while a narrow apex indicates high death rates or short life expectancy. The overall shape helps identify the stage of the demographic transition model, or DTM.
人口金字塔显示年龄和性别结构。底部宽说明出生率高，顶部窄说明死亡率高或预期寿命短。整体形状有助于判断人口转变模型（DTM）的阶段。
dency ratio = ((population aged 0-14 + population aged 65+) ÷ population aged 15-64) × 100
A high dependency ratio means more young and old people rely on the working-age group. This places pressure on healthcare, education and pension systems. Many exam questions ask you to calculate the ratio and then explain one social or economic consequence.
抚养比高意味着更多少儿和老人依赖劳动年龄人口，这会给医疗、教育和养老金体系带来压力。许多考题要求计算抚养比，然后解释一种社会或经济后果。
| Pyramid shape | Main feature | Typical DTM stage |
|---|---|---|
| Expansive | W
