CIE IGCSE 地理试卷四（替代课程作业）是一场时长1小时30分钟的笔试，考查你像野外地理学家一样运用实践技能的能力，占总成绩的27.5%。你将根据假设的田野调查情景回答问题，内容涵盖数据收集、呈现、分析、地图判读和评价。本指南将分解每一项核心技能、常见题型和考官的期望，帮助你提升成绩并获得对地理学的深层、实践性理解。
1. Understanding the Paper 4 Exam Format | 了解试卷四考试形式
Paper 4 is divided into two compulsory sections, A and B, each carrying 30 marks. Section A is based on a physical geography investigation (e.g. river processes or coastal management), while Section B focuses on a human geography investigation (e.g. urban land use or tourism). Both sections follow a logical sequence: from stating hypotheses and describing data collection methods, to presenting data in graphs or maps, analysing trends, and finally evaluating the reliability of the fieldwork and suggesting improvements.
试卷四分为两个必答部分，A和B，各占30分。A部分基于一个自然地理调查（如河流作用或海岸管理），B部分则侧重于人文地理调查（如城市土地利用或旅游业）。两部分都遵循逻辑顺序：从陈述假设、描述数据收集方法，到用图表或地图呈现数据、分析趋势，最后评价田野调查的可靠性并提出改进建议。
Each question is stepped and often contains multiple sub‑questions, such as completing a graph, measuring on a map, calculating a mean, or explaining a limitation. You must read the resource material (maps, photographs, tables) carefully before writing your answers. The timings suggest spending roughly 45 minutes per section.
每道题呈阶梯式，通常包含多个子问题，例如完成图表、在地图上测量、计算平均值或解释某一局限性。答题前必须仔细阅读所提供的资源材料（地图、照片、表格）。时间分配建议每部分约45分钟。
2. Formulating Hypotheses and Enquiry Questions | 制定假设与探究问题
A hypothesis is a clear, testable statement that predicts an outcome. In Paper 4, you will often be asked to write a suitable hypothesis for a given investigation. A well‑constructed hypothesis should mention the key variables (e.g. distance from source, channel depth) and suggest a direction of change. For example: ‘Channel width increases with distance downstream.’
假设是一个清晰、可检验的陈述，用于预测结果。试卷四常要求为所给的调查写出合适的假设。一个结构良好的假设应提及关键变量（如距源头的距离、河道深度）并暗示变化方向。例如：“河道宽度随离源头距离增加而增大。”
You may also be required to turn a research aim into a hypothesis or to identify which question best tests a hypothesis. Remember that a hypothesis is not a question; it is a statement that can be supported or rejected by evidence. Always phrase hypotheses in the context of the given location or theme.
你还可能被要求将研究目的转变为假设，或辨别哪个问题最能检验假设。记住假设不是问句，而是一个可供证据支持或拒绝的陈述。务必根据题目给出的地点或主题来措辞。
3. Fieldwork Techniques: Sampling Methods | 田野调查技巧：抽样方法
To collect representative data without measuring every individual, geographers use sampling. The three main types examined are random, systematic and stratified sampling. Each has strengths and weaknesses that can affect the reliability of results.
为了不测量每一个个体而获得具有代表性的数据，地理学家利用抽样。考查的三种主要类型是随机抽样、系统抽样和分层抽样。每种方法各有优缺点，会影响结果的可靠性。
| Method | Description | Advantage | Limitation |
|---|---|---|---|
| Random | Selecting sites using random number tables or generators; every location has an equal chance of being chosen. | Reduces bias; gives a true representation of the whole area. | May cluster sites or miss important features; difficult in inaccessible terrain. |
| Systematic | Collecting data at regular intervals (e.g. every 50 metres along a transect or every 10th person). | Quick and easy; good for measuring continuous change along a line. | May follow a pattern that misses variation; bias if the interval coincides with a hidden pattern. |
| Stratified | Dividing the population into subgroups (strata) and then sampling proportionally from each. | Ensures all key groups are represented; useful when characteristics vary widely. | Requires prior knowledge of the area to define strata; can be time‑consuming. |
In the exam, you may need to justify why a particular sampling strategy was used; always link your justification to the aim of the investigation and the physical or human geography involved.
在考试中，你可能需要论证为什么使用了某种特定的抽样策略；务必把论证与调查目的以及所涉及的自然或人文地理联系起来。
4. Primary and Secondary Data Collection | 一手与二手数据收集
Primary data is information you collect yourself through methods like questionnaires, traffic counts, river depth measurements, pebble angularity recordings or land‑use surveys. Secondary data is pre‑existing information, such as census statistics, weather records, historical maps or published reports.
一手数据是你自己通过问卷调查、交通流量计数、河流深度测量、卵石磨圆度记录或土地利用调查等方法收集的信息。二手数据是已有的信息，如人口普查统计、气象记录、历史地图或已发表的报告。
Examiners expect you to be able to describe methods precisely. For example, when describing a river velocity measurement, you should mention using a float or flowmeter, measuring a set distance (e.g. 10 m), timing with a stopwatch, and repeating three times for reliability. When discussing questionnaires, mention open/closed questions, sampling type and ethical considerations.
考官期望你能准确描述方法。例如，描述河流流速测量时，应提及使用浮标或流速计、测量固定距离（如10米）、用秒表计时并重复三次以确保可靠性。在讨论问卷时，要提及开放式/封闭式问题、抽样类型和道德考量。
Always evaluate: is primary data more accurate but time‑consuming? Does secondary data save time but risk being outdated? Weighing these factors demonstrates higher‑level thinking.
始终要评价：一手数据更精确但耗时吗？二手数据节省时间但有数据过时的风险吗？权衡这些因素能展示高阶思维。
5. Data Presentation: Graphs and Charts | 数据呈现：图表
Choosing the correct graph is an essential Paper 4 skill. The table below summarises the most frequently tested types and their best uses.
选择正确的图表是试卷四的一项核心技能。下表总结了最常考查的图表类型及其最佳用途。
| Graph type | When to use | Key tips |
|---|---|---|
| Bar chart | Comparing discrete categories (e.g. land‑use types, settlement functions) | Leave equal gaps between bars; label axes clearly. |
| Line graph | Showing continuous change over time or distance (e.g. river discharge, temperature changes) | Plot points accurately and join with a smooth line or straight ruler depending on the data. |
| Scatter graph | Investigating relationships between two variables (e.g. pebble size and distance downstream) | Draw a line of best fit to show correlation strength; do not connect dots. |
| Pie chart | Showing proportions of a total (e.g. percentage of different transport modes) | Calculate angles (percentage × 3.6); label each segment or provide a key. |
| Rose diagram | Displaying directional data (e.g. longshore drift, wind direction) | Draw bars radiating from the centre to the correct compass bearing and length. |
Always include a title, labelled axes (with units), and a neatly presented key if needed. In the exam, you may be asked to complete a partially drawn graph; use pencil and a ruler, and transfer data accurately.
始终要有标题、坐标轴标签（含单位），必要时有整洁的图例。考试中可能要求完成部分绘制好的图表；使用铅笔和直尺，准确转绘数据。
6. Maps and Photographs in Geography | 地理中的地图与照片
Map skills are tested frequently. You must be confident using four‑figure and six‑figure grid references, measuring straight‑line and curved distances (using string and scale bar), calculating area, identifying compass directions, and interpreting contour lines to describe relief.
地图技能频繁考查。你必须熟练运用四位和六位网格坐标、测量直线和曲线距离（用细绳和比例尺）、计算面积、辨识罗盘方向，以及解读等高线以描述地形。
A common task is to draw or complete a cross‑section between two points. Follow these steps: (1) Place a strip of paper along the line. (2) Mark where each contour line crosses. (3) Label heights. (4) Transfer points onto graph paper and join smoothly.
一项常见任务是绘制或完成两点之间的地形剖面图。步骤如下：（1）把纸条沿线段放置。（2）标记每条等高线的交点。（3）标注高度。（4）将点转绘到方格纸上并平滑连接。
Photograph analysis requires you to annotate features, compare two scenes, or suggest evidence for a hypothesis. Use geographical terms (e.g. ‘vertical erosion’, ‘gentrification’) and point directly to physical or human features visible in the image.
照片分析要求你注释特征、比较两个场景或为假设提供证据。使用地理术语（如“垂直侵蚀”、“绅士化”），并直接指出图像中可见的自然或人文特征。
7. Statistical Analysis Made Simple | 简单的统计分析
Paper 4 will often require you to calculate basic statistics to support your findings. You do not need advanced methods, but you must show workings and state answers clearly. The most common statistics are the mean, median, mode and range.
试卷四常要求计算基本统计量以佐证你的发现。不需要高级方法，但你必须展示计算过程并清晰地陈述答案。最常见的统计量是平均值、中位数、众数和极差。
Mean = Σx / n
Range = maximum value – minimum value
When calculating the mean, sum all values (Σx) and divide by the number of readings (n). Always mention the correct units. For the median, arrange data in ascending order and pick the middle value. The range is a simple measure of spread; a larger range suggests greater variability in the data.
计算平均值时，将所有数值求和 (Σx) 再除以数据个数 (n)。务必带上正确的单位。中位数是将数据按升序排列后取中间的值。极差是离散程度的简单量度；极差越大表明数据变异性越大。
You may also be asked to describe a correlation from a scatter graph. Use phrases like ‘strong positive correlation’, ‘weak negative correlation’, or ‘no clear pattern’. Always support your statement by referring to the arrangement of points.
你还可能被要求根据散点图描述相关性。使用“强正相关”、“弱负相关”或“无明显模式”等短语。始终通过提及点的排列方式来支持你的判断。
8. Describing Patterns and Trends | 描述模式与趋势
Describing is about stating what you see, not why it occurs. Use the ‘TREE’ approach: Trend (general direction), Range (highest and lowest values), Exceptions (anomalies), and Evidence (quote data). For example: ‘The number of tourists generally increases from May to August, from 2000 to 7500 visitors. However, July shows an unexpected drop to 6000, which is an anomaly.’
描述是陈述你所看到的，而非为何发生。使用“TREE”方法：趋势（总体方向）、范围（最高和最低值）、例外（异常值）和证据（援引数据）。例如：“游客数量通常从5月到8月增加，从2000人增至7500人。然而，7月意外下降到6000人，这是一个异常值。”
Never jump into explanation too early. Marks are explicitly awarded for description of patterns on maps, graphs and photographs. Use comparatives and superlatives such as ‘steeper’, ‘more densely built‑up’, ‘least accessible’.
切勿过早跳到解释。在地图、图表和照片中描述模式是有明确赋分的。使用比较级和最高级，如“更陡峭”、“建筑更密集”、“最不易到达”。
When describing a river cross‑section, for instance, comment on gradient, symmetry, and width‑to‑depth ratio. Always link vocabulary to the visual evidence provided.
例如，描述河流横截面时，要评论坡度、对称性以及宽深比。始终将词汇与所提供的视觉证据联系起来。
9. Comparing and Explaining Data | 比较与解释数据
Comparison questions ask you to identify similarities and differences between two or more sets of data. Use linking phrases like ‘whereas’, ‘on the other hand’, ‘similarly’, and ‘in contrast’. For example: ‘Site A has a channel depth of 0.8 m, whereas Site B is twice as deep at 1.6 m.’
比较题要求你识别两组或多组数据之间的异同。使用连接短语，如“而”、“另一方面”、“相似地”和“与之相反”。例如：“地点A的河道深度为0.8米，而地点B深达1.6米，是前者的两倍。”
After comparing, you will typically be asked to explain the differences. Explanations must draw on geographical processes and theory. For instance, you might explain that the deeper channel at Site B is due to increased discharge and vertical erosion in the lower course. Always link back to the hypothesis.
比较之后，通常会要求你解释差异。解释必须运用地理过程和理论。例如，你可以解释地点B河道更深是由于下游流量增加和垂直侵蚀所致。始终与假设相联系。
Use a structured paragraph: P – Point, E – Evidence, E – Explanation, L – Link. This keeps your answers focused and gains full marks for analysis.
使用结构化段落：P – 观点, E – 证据, E – 解释, L – 联系。这能使你的答案聚焦，并在分析环节获得满分。
10. Evaluating Fieldwork and Limitations | 评估田野调查与局限性
Evaluation carries high marks. You must identify problems with the data collection methods or the data itself, and then suggest realistic improvements. Common limitations include: small sample size, bias in sampling, human error in measurements, weather conditions on the day, limited time, and equipment failure.
评价环节分值很高。你必须识别数据收集方法或数据本身的问题，然后提出可行的改进建议。常见的局限性包括：样本量小、抽样偏差、测量中的人为误差、当天的天气状况、时间有限以及设备故障。
For each limitation you identify, always explain why it matters and how it could affect the reliability or validity of the results. Then provide a specific improvement. For example: ‘Only five sites were sampled, which is too few to show the full pattern. Next time, sample at least 15 sites equally spaced along the river.’
对于所识别的每一项局限性，始终要解释它为何重要，以及它会如何影响结果的可靠性或有效性。然后提出具体的改进措施。例如：“只抽取了5个样本点，数量太少，无法显示全貌。下次可沿河等距设置至少15个样本点。”
Avoid vague statements like ‘do it more carefully’. Instead, give concrete actions: ‘use a digital anemometer instead of a hand‑held wind vane’, ‘take readings at the same time of day to control for diurnal variation’.
避免“做得更仔细”这样的空泛表述。相反，给出具体行动：“使用数字风速计替代手持风向标”、“在每天同一时间读数以控制日变化”。
11. Exam Tips and Common Mistakes | 考试技巧与常见错误
First, manage your time: check the mark allocation for each sub‑question and spend proportionally. Do not spend 15 minutes on a 2‑mark graph completion. Second, read the command words carefully: ‘describe’ means what, ‘explain’ means why, ‘suggest’ means offer a plausible idea, and ‘evaluate’ means weigh strengths and weaknesses.
首先，管理好时间：查看每个子问题的分值并按比例分配时间。不要在2分的图表补全题上花15分钟。其次，仔细阅读指令词：“描述”是指什么，“解释”是指为什么，“建议”是指给出一个合理的想法，“评价”是指权衡优劣。
Common mistakes include: forgetting to include units in data tables or on graph axes, writing a hypothesis as a question, describing rather than evaluating in the final section, and misreading map scales. Also, when drawing a line of best fit on a scatter graph, do not force the line through the origin unless it is logical to do so.
常见错误包括：数据表或坐标轴上忘记加单位、将假设写成问句、在最后部分只顾描述而不做评价、读错地图比例尺。此外，在散点图上绘制最适线时，除非合乎逻辑，否则不要强行让线穿过原点。
Finally, revise field sketches and land‑use mapping techniques, as drawing or completing a sketch map often appears. Practise with past papers, always using a pencil, ruler and calculator. Annotation must be done with a fine pen for clarity, while any drawing should be in pencil.
最后，复习野外速写和土地利用制图技巧，因为补绘或完成速写地图经常出现。用过往试卷练习，始终备好铅笔、直尺和计算器。注释须用细签字笔以求清晰，而任何绘图则应使用铅笔。
