GCSE地理 写作技巧 答题框架 评估题精讲
写作题是 GCSE 地理拿高分的关键。以 AQA 为例，Paper 1 和 Paper 2 都设有 6 分的 explain 解释题与 9 分的 evaluate 评估题，这两类题常常决定学生能否拿到 7 到 9 分。很多同学知识点背得很熟，分数却上不去，问题大多出在结构混乱、证据没有具体数据、以及评估题缺少判断。这篇文章给你一套完整的写作框架：从读懂指令词，到搭建答题结构，再到用好案例与数据，最后用真题示范带你把每个步骤走一遍。
Extended writing decides top grades in GCSE Geography. In AQA, for example, Papers 1 and 2 both contain 6-mark explain questions and 9-mark evaluate questions, and performance on these often separates grade 7 from grade 9. Many students know the content but lose marks because their answers lack structure, precise evidence, and judgement. This article gives you a complete writing framework: reading command words, building answer structures, using case studies and data, and working through real exam questions step by step.
1 指令词决定答题结构 Command words set your structure
看到题目先圈出指令词，它直接决定你要写什么。Describe 描述题通常占 2 到 3 分，只要从图或资料中挑出特征并引用具体数值，不需要解释原因。Explain 解释题占 4 到 6 分，核心是因果链：每写一步都要问自己「为什么」，把 A 导致 B、B 导致 C 的链条写完整。Assess 与 Evaluate 评估题占 6 到 9 分，要求两面都谈，最后必须有明确的判断。To what extent 与 evaluate 类似，同样要给出有保留的结论。
Circle the command word before you write, because it dictates your structure. A describe question, worth 2 to 3 marks, only needs features selected from the figure with precise values, with no causes required. An explain question, worth 4 to 6 marks, needs a causal chain: after every point ask why, and link A to B, then B to C. Assess and evaluate questions, worth 6 to 9 marks, need both sides of the argument plus a clear judgement. To what extent works like evaluate: argue both ways and end with a qualified conclusion.
时间分配也看分值：按照 1 分约 1 分钟来计划，6 分题大约写 6 到 8 分钟，9 分题预留 9 到 12 分钟并留下检查错别字的时间，因为 9 分题通常还带拼写和语法的分数（SPaG marks）。
Manage time by mark value: allow roughly one minute per mark. Spend about 6 to 8 minutes on a 6-mark question and 9 to 12 minutes on a 9-mark question, leaving time to check spelling, because 9-mark answers in AQA carry separate SPaG marks for accurate spelling, punctuation and grammar.
2 Explain 解释题：因果链框架
6 分解释题最稳的写法是四步框架：第一步直接给出核心原因，一句话点题；第二步把因果链条写出来，每一个环节用 because、so、which means 这类连接词扣紧；第三步用案例或数据让链条落地，地名加数字最有说服力；第四步回扣题目，用题目里的关键词收尾，防止判卷老师觉得你跑题。
The safest structure for a 6-mark explain question has four steps. First, state the core reason in one sentence. Second, build the causal chain, linking every step with connectives such as because, so, and which means. Third, anchor the chain with a case study or data, since a named place with figures is far more convincing. Fourth, link back to the question and finish with its key terms so the examiner can see you stayed on topic.
看一个范例：Explain how urbanisation increases flood risk 城市化如何加剧洪水风险。示范答案：城市化让地面变成混凝土和柏油等不透水表面，雨水无法下渗，大部分变成地表径流；下水道又把水快速排入河道，导致河流滞后时间变短、洪峰流量更高，洪水发生的机会因此上升。这条答案的得分点就在链条完整：不透水、下渗减少、径流增加、峰值提前、风险上升，环环相扣。
Here is a model: explain how urbanisation increases flood risk. Urban areas are covered with impermeable surfaces such as concrete and tarmac, so rainfall cannot infiltrate and most becomes surface runoff. Drains carry this water rapidly into rivers, shortening lag time and raising peak discharge, which increases the chance of flooding. Full marks come from the complete chain: impermeable surfaces, less infiltration, more runoff, faster peak flow, higher flood risk.
3 Evaluate 评估题：两面论证加判断
9 分评估题是拿 9 的试金石，推荐用五段骨架：第一段亮明总体立场，并说明你用什么标准判断，例如经济效益、环境影响还是社会公平；第二段写正方观点，配一个案例并解释机制；第三段写反方观点，同样用具体证据；第四段做权衡，说明哪个因素最关键、为什么它比另一边更重要；第五段下结论，可以是有保留的判断，例如「总体上利大于弊，但对低收入社区而言成本过高」。
The 9-mark evaluate question is where grade 9s are won. Use a five-paragraph skeleton. Open by stating your overall position and your criteria, such as economic benefit, environmental impact, or social fairness. Then present the supporting argument with a case study and explain the mechanism. Next present the opposing view with concrete evidence. Then weigh the two sides, saying which factor matters most and why it outweighs the other. Finally conclude with a judgement, possibly a qualified one, for example on balance the benefits outweigh the costs, but the burden is too heavy for lower-income communities.
评估题还需要一套自己的句式。正方常用：On one hand 一方面、This approach is effective because 这种方法之所以有效，是因为、The evidence from 来自某地的证据表明。反方常用：On the other hand 另一方面、However, its main limitation is 然而它的主要局限在于、This solution only works when 这种方案只在某种条件下有效。收尾判断常用：On balance, I believe 总体而言我认为、The most decisive factor is 最决定性的因素是、In conclusion, although 结论是，尽管。把这些句式与案例素材组合，考场上就能快速组织出结构完整的评估段。
Evaluation questions need their own sentence starters. For the supporting side use: on one hand, this approach is effective because, and the evidence from place X shows that. For the opposing side use: on the other hand, however its main limitation is, and this solution only works when. For the conclusion use: on balance I believe, the most decisive factor is, and in conclusion although. Combine these starters with your case material and you can assemble a well-structured evaluation paragraph quickly under exam pressure.
示范素材：评估硬工程是否是最好的防洪办法。正方用泰晤士河闸：1982 年启用，保护伦敦约 125 万人，多次在风暴潮中挡住洪水，是英国最关键的防洪设施之一。反方用约克郡 2015 年洪水：工程挡墙在高强度降雨面前仍被漫顶，说明硬工程应对极端天气有上限，而且建造与维护成本极高。权衡时可以说：硬工程在人口密集的核心区最有效，但必须与上游植树、湿地恢复等软工程配合，才能应对越来越强的暴雨。
Sample material: evaluate whether hard engineering is the best way to manage flooding. For the argument, use the Thames Barrier, opened in 1982, which protects about 1.25 million people in London and has stopped storm surges reaching the capital on many occasions. Against the argument, use the 2015 floods in York, where flood walls were overtopped by extreme rainfall, showing that hard defences have limits and carry very high construction and maintenance costs. In weighing up, say hard engineering works best in densely populated core areas, but it must be combined with soft engineering such as upstream afforestation and wetland restoration to cope with more intense storms.
4 案例研究：建立你的证据库
高分答案离不开高质量案例。建议每个主题准备两个案例：一个来自高收入国家，一个来自中低收入国家，形成对比。每个案例只记四类信息：地点与日期、关键数据、主要影响、具体应对措施。比如尼泊尔 2015 年 7.8 级地震，约 9000 人死亡，经济损失接近 GDP 的四分之一，应对以国际救援和帐篷安置为主；对比日本 2011 年 9.0 级地震，严格的抗震建筑标准让大部分建筑未倒塌，说明防灾投入的长期价值。
High-scoring answers depend on high-quality case studies. Prepare two per topic, one from a high-income country and one from a low or middle-income country, so you can compare. For each case memorise only four things: place and date, key data, main effects, and specific responses. Compare Nepal, where the 2015 magnitude 7.8 earthquake killed about 9,000 people and caused damage worth nearly a quarter of GDP, with Japan, where strict building codes kept most structures standing during the 2011 magnitude 9.0 earthquake, showing the long-term value of investment in preparedness.
写作时用 PEEL 结构组织每一段：Point 先亮观点，Evidence 给案例数据，Explain 解释其中机制，Link 把案例与题目观点连起来。没有地名的案例等于没有证据，写「某发展中国家发生地震」得不了分，必须写清 Nepal、Haiti 或 Japan。
Organise each paragraph with PEEL: Point states your idea, Evidence supplies case data, Explain works out the mechanism, and Link connects the case back to the question. A case without a name is not evidence. Writing that an earthquake hit a developing country earns nothing, so name Nepal, Haiti or Japan and give the figures.
5 数据与图表题：用数字说话
描述图表趋势最忌一句「它上升了」。必须引用起点与终点数值和时间范围，例如「1990 到 2020 年间，城市人口比例从 10% 上升到 35%」，再补充变化幅度，例如「增加了 25 个百分点」或「接近原来的 3.5 倍」。比较两地的数据要用比较结构，例如「A 地的数值是 B 地的两倍以上」。
Never answer a data question with the phrase it went up. Quote the start value, the end value and the time period, for example the urban population share rose from 10% to 35% between 1990 and 2020, then add the scale of change, such as an increase of 25 percentage points or nearly 3.5 times the original figure. When comparing two places, use comparative language, for example the value in place A is more than twice that in place B.
积累一组描述词能明显提分：steadily increased 稳步上升、rapid growth 快速增长、fluctuated 波动、peaked at 达到峰值、trough 低谷、recovered 回升。判断趋势时先看整体方向，再抓极端年份，最后算变化幅度，三步把 3 分拿满。
Build a vocabulary bank for trends: steadily increased, rapid growth, fluctuated, peaked at, trough, and recovered. When reading a graph, first state the overall direction, then pick out extreme years, then calculate the size of the change. These three steps secure full marks on data description.
6 术语与衔接词：让表达更专业
写作题的语言分来自两个地方：准确的主题术语和清晰的衔接。自然地理常用词包括 discharge 流量、lag time 滞后时间、infiltration 下渗、erosion 侵蚀、deposition 沉积、tectonic hazard 构造灾害；人文地理常用词包括 urban sprawl 城市蔓延、gentrification 绅士化、globalisation 全球化、TNC 跨国企业、ageing population 人口老龄化。每周背五到十个，拼写必须正确，因为拼写错误会直接扣掉 SPaG 分数。
Language marks come from two sources: precise topic vocabulary and clear connectives. Physical geography words you need include discharge, lag time, infiltration, erosion, deposition, and tectonic hazard. Human geography words include urban sprawl, gentrification, globalisation, TNC, and ageing population. Learn five to ten terms each week and spell them correctly, because errors cost SPaG marks.
段落之间的衔接词同样重要：This is because 用于解释原因，As a result 引出结果，However 与 On the other hand 引出反方观点，More importantly 强调更关键的因素，On balance 用于最终判断。把这些词当作路标，考官才能顺着你的逻辑走。
Connectives matter just as much: This is because introduces a reason, As a result signals a consequence, However and On the other hand open the counter-argument, More importantly highlights the decisive factor, and On balance introduces the final judgement. Treat these words as signposts that guide the examiner through your logic.
7 常见失分点与提分清单
最后对照这份失分清单自查。第一，指令词理解错：题目要 explain 你却写成 describe，整段白写。第二，案例太笼统：没有地名、没有数字。第三，评估题只有一面，或者有观点没结论。第四，时间失衡：在 2 分题上花 10 分钟，9 分题只剩 5 分钟。第五，忽视 SPaG：连 Geography 都拼错会直接扣分。第六，结尾不回扣题目关键词，让答案看起来像背好的段落。
Check your work against this list of common traps. First, misreading the command word: writing a description when the question asks for an explanation wastes the whole paragraph. Second, vague case studies with no place name and no data. Third, one-sided evaluation or a judgement with no conclusion. Fourth, poor timing: ten minutes on a 2-mark question leaves five minutes for a 9-mark one. Fifth, ignoring SPaG: misspelling Geography itself costs marks. Sixth, endings that never return to the question's key terms, making a good answer look like a memorised paragraph.
把本文学到的框架做成自己的模板：指令词定结构，explain 走因果链，evaluate 走两面加判断，案例必须带地名和数据，图表题用数字和趋势词，段落用衔接词串起来。考前每周限时练两道真题，一道 6 分一道 9 分，写完后对照评分标准自查。坚持一个月，写作分数会明显提升。
Turn this article into your own template: let the command word set the structure, build causal chains for explain, argue both sides and judge for evaluate, always name places and give data, describe graphs with figures and trend language, and stitch paragraphs together with connectives. Every week before the exam, practise two past-paper questions under timed conditions, one 6-mark and one 9-mark, then mark yourself against the official mark scheme. One month of this routine will visibly raise your writing score.
