Understand biographies, event narratives and source notes.
Distinguish historical fact, source claim and later evaluation.
Write an evidence-aware historical introduction.
LEARN IN CONTEXT
Read and listen across several real contexts
This lesson uses the number and type of texts that fit the topic. Learn the same language across different situations instead of forcing everything into one dialogue.
Core textShort article
同一历史事件为什么会有不同日期
Why this text is here: Distinguish event stages and dating conventions.
历史事件有时不是在一天内完成。有人把第一次公开行动作为开始，有人把正式文件发布作为节点，还有研究者按地方实际执行时间记录。因此，同一事件在不同资料里可能出现相邻但不同的日期。Historical events are not always completed in one day. Sources may date the first public action, a formal document or local implementation, producing nearby but different dates.
看到日期差别时，第一步不是判断哪份资料“肯定错了”，而是检查每份资料在给哪个阶段标日期。只有定义相同，日期才适合直接比较。When dates differ, first check which stage each source labels rather than assuming one is wrong. Direct comparison requires matching definitions.
Practical textProfile
一段人物传记里哪些是事实，哪些是后来评价
Why this text is here: Separate dated actions, attributed statements and retrospective interpretation.
一篇人物传记写道，某官员在任期间主持修建水利工程，并引用地方档案记录工程完成年份。这部分有明确资料来源。文章随后说“他一生最大的愿望就是改变家乡”，却没有给出书信、日记或当时人的记录。A biography states that an official led a water project and cites a local archive for its completion year. That part has a clear source. It then says his greatest lifelong wish was to transform his hometown, without letters, diaries or contemporary records.
Gèng zhǔnquè de xiěfǎ kěyǐ gǎi chéng: “Hòulái yìxiē dìfāng wénzhāng bǎ zhè xiàng gōngchéng jiěshì wéi tā guānxīn jiāxiāng de biǎoxiàn.” Zhèyàng bǎoliú le hòulái píngjià, què méiyǒu bǎ píngjià biàn chéng wúfǎ zhèngmíng de nèixīn yuánhuà.
更准确的写法可以改成：“后来一些地方文章把这项工程解释为他关心家乡的表现。”这样保留了后来评价，却没有把评价变成无法证明的内心原话。A more accurate wording attributes that interpretation to later local writing. It preserves retrospective evaluation without turning it into unverified inner speech.
历史介绍先交代时代背景，再比较不同资料之间的差别。A history introduction should establish period context and compare differences among sources.
参考报告表达表明
Shǐliào kěyǐ zuòwéi cānkǎo, dàn yí fèn hòulái bàogào de biǎodá bù néng zìdòng biǎomíng dāngshí rén de zhēnshí xiǎngfǎ.
史料可以作为参考，但一份后来报告的表达不能自动表明当时人的真实想法。Historical sources can be references, but later reporting cannot automatically reveal a historical person's actual thoughts.
概括长期
Gàikuò lìshǐ shìjiàn shí yào bǎoliú chángqī yuányīn hé zhíjiē chùfā yīnsù zhījiān de qūbié.
概括历史事件时要保留长期原因和直接触发因素之间的区别。Historical summaries should distinguish long-term causes from immediate triggers.
Study the pattern, then replace the example information with details from your own situation.
假设复句用于历史反事实边界
假如/万一/一旦……
Use hypothetical forms to discuss possibilities, while clearly marking them as hypothetical rather than historical fact.
Jiǎrú quēshǎo dāngshìrén de zhíjiē jìlù, wǒmen jiù bù néng bǎ hòulái zuòzhě de tuīcè xiě chéng tā de yuánhuà.假如缺少当事人的直接记录，我们就不能把后来作者的推测写成他的原话。If direct records are absent, later authors' speculation cannot be written as the person's own words.
因果复句用于历史解释
原因/证据，因而……；……，可见……
Link evidence and consequence while avoiding single-cause explanations.
Liánxù qiànshōu shǐ liángjià shàngzhǎng, yīn'ér chéngshì yālì zēngjiā; dàn zhè zhǐshì duō gè yīnsù zhī yī.连续歉收使粮价上涨，因而城市压力增加；但这只是多个因素之一。Repeated poor harvests raised grain prices and increased urban pressure, but this was only one of several factors.
