1. Cause and Consequence Formula | 因果关系公式
The core formula for explaining why events happen: ger + Long-term Causes + Short-term Causes = Event → Consequences (intended & unintended). Always layer your causes — social, economic, political, cultural — and rank them by significance. A single trigger is never enough; look for the deeper structures.
解释事件为何发生的核心公式：导火索 + 长期原因 + 短期原因 = 事件 → 后果（预期和意外）。 始终将原因分层——社会、经济、政治、文化——并按重要性排序。单一导火索永远不够；要寻找更深层的结构。
Worked example: The First World War. Trigger: assassination of Archduke Franz Ferdinand (1914). Long-term causes: militarism, alliances, imperialism, nationalism (MAIN). Short-term causes: Balkan crises, mobilisation plans. Consequence: the war itself, plus unintended outcomes like the collapse of empires and the rise of the USA.
示例应用：第一次世界大战。 导火索：弗朗茨·斐迪南大公遇刺（1914 年）。长期原因：军国主义、同盟体系、帝国主义、民族主义（MAIN）。短期原因：巴尔干危机、动员计划。后果：战争本身，加上帝国崩溃与美国崛起等意外结果。
2. Change and Continuity Theorem | 变革与延续定理
History rarely flips overnight. The theorem: Rate of Change × Depth of Change = Significance of Transformation. Rate can be rapid (revolution) or gradual (evolution). Depth ranges from surface tweaks to total transformation. Always identify what remained the same amidst change — continuity often holds societies together.
历史很少一夜变天。定理：变革速度 × 变革深度 = 变革的重要性。 速度可以是急剧的（革命）或渐进的（演进）。深度涵盖从表面调整到彻底转型。始终找出变革中保持不变的东西——延续性往往维系着社会。
Worked example: The Industrial Revolution c.1750–1900. Economic change was rapid and deep: factories, steam power, urbanization. Yet political continuity persisted: the landed aristocracy retained influence, and working-class men did not get the vote until later reforms. Social customs around family and religion also showed strong continuity.
示例应用：工业革命（约 1750–1900 年）。 经济变革迅速而深刻：工厂、蒸汽动力、城市化。但政治延续性持续存在：土地贵族保留影响力，工人阶级男性直到后期改革才获得选举权。家庭和宗教方面的社会习俗也表现出强大的延续性。
3. Similarity and Difference Principle | 相似与差异原理
This principle states: Comparison = Contextual Similarities + Key Differences + Significance of the Gap. When comparing two periods, groups, or events, don't just list features. Explain whether similarities or differences matter more. Use categories like technology, beliefs, and power.
本原理指出：比较 = 背景相似性 + 关键差异 + 差异的重要性。 在比较两个时期、群体或事件时，不要只罗列特征。解释相似点还是差异点更重要。使用技术、信仰和权力等范畴。
Worked example: Medieval vs Renaissance medicine. Similarities: both relied on Galen’s theories for centuries, and religion influenced treatment. Differences: Renaissance saw the rise of dissection, observational anatomy (Vesalius), and a challenge to ancient authority. The difference in attitude toward empirical evidence proved hugely significant for scientific progress.
示例应用：中世纪医学与文艺复兴医学。 相似点：两者都长期依赖盖伦学说，宗教影响治疗。差异点：文艺复兴出现解剖实践、观察解剖学（维萨里）以及对古代权威的挑战。对待经验证据的态度差异对科学进步意义重大。
4. Historical Significance Law | 历史意义定律
The law: ignificance = Impact (depth & breadth) + Resonance over time + Revelation of wider trends. An event might be remembered because it affected millions, sparked lasting change, or symbolised something bigger. Significance is not fixed — it’s constructed by later generations.
定律：意义 = 影响（深度与广度） + 时间上的回响 + 揭示更大趋势。 一个事件可能因影响数百万人、引发持久变化或象征更大事物而被铭记。意义并非固定不变——它是由后代构建的。
Worked example: The signing of the Magna Carta 1215. At the time, it was a failed peace treaty between king and barons. Its impact was limited to the elite. Yet over centuries, it resonated as a symbol of the rule of law and limited monarchy, inspiring later democratic documents. Its significance grew retrospectively.
示例应用：《大宪章》签署（1215 年）。 当初它只是国王与贵族间一项失败的和约，影响局限于精英阶层。但数百年里，它作为法治和有限君主制的象征产生回响，启发了后来的民主文件。其意义是事后不断增长的。
5. Evidence Source Check | 史料证据检查公式
Analyse any source with the formula: NATURE + ORIGIN + PURPOSE = Utility & Reliability. Nature: what type of source (diary, speech, photograph)? Origin: who created it, when, where? Purpose: why was it made? Then cross-reference with your own knowledge to confirm or challenge the source’s claims.
分析任何史料使用公式：性质 + 出处 + 目的 = 有用性与可靠性。 性质：什么类型的史料（日记、演讲、照片）？出处：谁、何时、何地创作的？目的：为什么而作？然后结合你自己的知识进行交叉参照，以确认或质疑史料中的说法。
Worked example: A 1915 British recruitment poster. Nature: government propaganda poster. Origin: produced by the Parliamentary Recruiting Committee in London, 1915. Purpose: to encourage men to enlist by appealing to patriotism and guilt. Utility: useful for studying government attitudes and propaganda techniques, but unreliable for facts about trench life. Reliability is limited by deliberate one-sidedness.
示例应用：1915 年英国征兵海报。 性质：政府宣传海报。出处：由议会征兵委员会于 1915 年在伦敦制作。目的：通过诉诸爱国主义和愧疚感鼓励男性参军。有用性：对于研究政府态度和宣传技巧很有用，但作为描述战壕生活的事实则不可靠。可靠性因刻意片面而大打折扣。
6. Interpretation and Perspective Rule | 解释与视角规则
Historical interpretations are shaped by a rule: Interpretation = Evidence Available + Historian’s Context + Purpose. Two historians using the same facts may reach opposite conclusions because of their own time period, political stance, or school of thought. Always ask: why does this interpretation exist, and who benefits from it?
历史解释受一条规则制约：解释 = 现有证据 + 历史学家的背景 + 目的。 两位使用相同事实的历史学家可能得出相反结论，因为他们所处的时代、政治立场或思想流派不同。永远要问：这个解释为何存在，它对谁有利？
Worked example: Interpretations of the British Empire. Victorian historians often portrayed the Empire as a civilising mission, emphasising railways and legal systems. Postcolonial historians highlight exploitation, cultural destruction, and racism. Both draw on evidence but frame it differently due to changing values and new archival discoveries.
示例应用：对大英帝国的解释。 维多利亚时代的史学家常将帝国描绘成文明开化使命，强调铁路和法律制度。后殖民史学家则突出剥削、文化破坏和种族主义。双方都依据证据，但因价值观变化和新档案发现而构建不同叙述。
7. Chronology and Periodisation Formula | 年代与分期公式
Periodisation is a historian’s organising formula: Start Date + Turning Point + End Date = Historical Period. But turning points are often debated. A good chronology question tests whether you can link events in a logical sequence and explain how one led to another. Use timelines as mental skeletons.
历史分期是历史学家的组织公式：起始日期 + 转折点 + 结束日期 = 历史时期。 但转折点常有争议。好的年代排序题考察你能否按逻辑顺序串联事件，并解释一件事如何导致另一件事。把时间轴当作思维骨架。
Worked example: The Cold War periodisation. Many textbooks start with the 1945 Yalta Conference and end with the dissolution of the USSR in 1991. Key turning points: Berlin Blockade 1948–49, Cuban Missile Crisis 1962, Fall of Berlin Wall 1989. A strong essay would explain why these moments redefined the period.
示例应用：冷战分期。 许多教科书以 1945 年雅尔塔会议为起点，以 1991 年苏联解体为终点。关键转折点：1948–49 年柏林封锁、1962 年古巴导弹危机、1989 年柏林墙倒塌。一篇好论文会解释这些时刻为何重新定义了该时期。
8. Historical Argument Structure | 历史论证结构公式
Build every paragraph with the PEEL formula: Point – Evidence – Explanation – Link. State your argument clearly, then back it with specific facts, dates, or statistics. Explain how the evidence supports your point, showing cause and consequence or change and continuity. Finally, link back to the question and transition to the next idea. This turns description into analysis.
用 PEEL 公式构建每个段落：观点 – 证据 – 解释 – 链接。 清晰陈述你的论点，然后用具体事实、日期或统计数据支持。解释证据如何支撑你的观点，展示因果关系或变革与延续。最后，回扣问题并过渡到下一个观点。这能将描述转化为分析。
Worked example: Question on why women got the vote in 1918. Point: The war work of women was a crucial turning point. Evidence: by 1918 over 700,000 women had worked in munitions factories. Explanation: it shattered the Victorian myth that women were too fragile for public life, making their exclusion from the vote look outdated. Link: however, the pre-war suffragette campaigns had already laid the groundwork for change.
示例应用：关于女性为何在 1918 年获得选举权的题目。 观点：女性的战时工作是关键转折点。证据：到 1918 年有超过 70 万女性在军火工厂工作。解释：这打破了维多利亚时代女性过于脆弱、不适合公共生活的神话，使排斥她们选举权显得过时。链接：然而，战前的妇女参政运动早已为变革奠定基础。
9. Primary vs Secondary Source Formula | 一手史料与二手史料公式
Use this simple distinction: Primary = from the time (eyewitness, artefact, original document). Secondary = after the time (textbook, documentary, historian’s book). But a source can be both depending on the question. A 1950s textbook about the Industrial Revolution is a secondary source for that event, but a primary source for 1950s attitudes towards industry.
使用这个简单区分：一手史料 = 来自当时（目击者、文物、原始文件）。二手史料 = 事后（教科书、纪录片、历史学家著作）。但同一份史料根据问题可一身兼两职。一本 1950 年代关于工业革命的教科书，对于该事件是二手史料，但对 1950 年代对待工业的态度则是一手史料。
Worked example: A letter from a soldier in the trenches, 1916. For a question on conditions on the Western Front, it’s primary. For a question on how later generations remembered the war, it could be used as evidence of individual experience that contrasts with later myths. Always justify your classification in an exam answer.
示例应用：一封 1916 年战壕士兵的家信。 对于关于西线战况的问题，它是一手史料。对于关于后代如何记忆战争的问题，则可作为个人经历的佐证，与后来的神话形成对比。考试作答时务必说明你分类的依据。
10. Bias and Reliability Diagnostic | 偏见与可靠性诊断公式
Bias doesn’t make a source useless — it makes it interesting. The diagnostic: Bias = Creator’s perspective + Intended effect on audience. Reliability depends on how well the source can be cross-checked against other evidence. A biased source can still be reliable for revealing attitudes, even if its factual claims are shaky.
偏见不会让史料毫无价值——它反而使之有趣。诊断方法：偏见 = 创作者视角 + 对受众的预期效果。 可靠性取决于该史料能与多少其他证据相互印证。一份有偏见的史料在揭示态度方面可能依然可靠，即使其事实性描述不够坚实。
Worked example: Mussolini’s speech on the invasion of Abyssinia, 1935. Bias: Fascist propaganda, exaggerating Italian greatness and Abyssinian ‘backwardness’. Reliability for facts: low — he lies about casualty numbers. Reliability for attitudes: high — the speech reveals Fascist ideology and imperial ambition perfectly. Always say what a source is useful for.
示例应用：墨索里尼关于入侵阿比西尼亚的演讲，1935 年。 偏见：法西斯宣传，夸大意大利的伟大和阿比西尼亚的“落后”。事实可靠性：低——他在伤亡数字上撒谎。态度可靠性：高——该演讲完美揭示了法西斯意识形态和帝国野心。始终说明一份史料对什么研究目的有用。
11. Empathy and Contextualisation Rule | 共情与情境化原则
Avoid present-mindedness. The rule: pathy = Understanding past actions within THEIR context, NOT judging by today’s standards. This does not mean excusing injustice; it means explaining why people thought or acted as they did based on the beliefs, knowledge, and pressures of their time. It makes your analysis richer and more academic.
避免以今度古。原则是：历史共情 = 在历史情境中理解过去行为，而非以今天标准评判。 这不意味着为不公正开脱，而是依据当时人们的信念、知识和压力，解释他们为什么那样思考或行动。这会让你的分析更深刻、更具学术性。
Worked example: Support for child labour in the 1800s. To modern eyes, it’s indefensible. But many working-class families relied on children’s wages for survival, and even reformers accepted gradual change because the alternative was seen as starvation. Contextualising doesn’t justify, but explains.
示例应用：19 世纪对童工的支持。 在现代人眼中无法容忍，但许多工人阶级家庭靠孩子工资存活，甚至改革者也接受渐进变革，因为替代方案被视为饥饿。情境化不是开脱，而是解释。
12. The Big Picture Revision Formula | 全局复习公式
When revising, don’t just memorise isolated facts. Use: Big Picture = Thematic threads × Chronological anchors × Key individuals. Identify themes (power, religion, technology, ideas) and track them across units. Pin key dates as chronological anchors, then people your timeline with individuals who drove or resisted change. This formula turns scattered knowledge into a coherent story.
复习时不要只死记孤立事实。使用：全局 = 主题线索 × 时间锚 × 关键人物。 识别主题（权力、宗教、技术、思想），并跨单元追踪。将关键日期确定为时间锚，然后在时间线上填入推动或抵制变革的人物。这一公式能将零散知识转化为连贯的叙事。
Worked example: Thematic revision of power through Year 9 topics. From King John and Magna Carta to the English Civil War, to the extension of the franchise in the 19th century — trace the tug-of-war between monarchy, parliament, and the people. Use 1215, 1649, 1832, and 1918 as anchors. Each period adds a layer to the story of power shifting.
示例应用：穿越 Year 9 各主题的权力线索复习。 从约翰王与《大宪章》，到英国内战，再到 19 世纪选举权扩展——追踪君主、议会与人民之间的拉锯。将 1215、1649、1832 和 1918 年作为时间锚。每个时期都为权力转移的故事增添一层新含义。
