📚 CAIE Pre-U Spanish: Core Knowledge Review | CAIE Pre-U 西班牙语：核心知识点梳理
For CAIE Pre-U Spanish candidates, achieving top marks demands not only fluent communication but also precise control of advanced grammar, idiomatic range and the ability to analyse cultural topics. This resource distils the essential language building blocks most frequently tested across Paper 2 (Reading and Listening), Paper 3 (Writing) and Paper 4 (Topics and Texts). 对于 CAIE Pre-U 西班牙语考生，要取得高分不仅需要流利的交流能力，更需要对高级语法的精确掌控、丰富的惯用表达以及分析文化话题的能力。这份资料浓缩了在试卷二（阅读与听力）、试卷三（写作）和试卷四（话题与文本）中最常考查的核心语言构件。
Every concept is presented in paired English-Chinese explanations to reinforce understanding from both linguistic angles. 每一个知识点都以英中对照讲解的形式呈现，以便从两种语言角度加深理解。
1. Overview of Indicative Tenses | 陈述式时态总览
The present indicative forms the backbone of everyday Spanish. Regular -ar (hablo), -er (como) and -ir (vivo) endings follow clear rules, while stem-changing verbs (pensar > pienso, poder > puedo) and common irregulars such as ‘tener’, ‘ir’ and ‘hacer’ must be internalised. 陈述式现在时是日常西语的基石。以 -ar (hablo)、-er (como) 和 -ir (vivo) 结尾的规则动词遵循清晰的规则，而词干变化动词（pensar > pienso, poder > puedo）以及常见的不规则动词如 ‘tener’、’ir’ 和 ‘hacer’ 则须牢记。
The preterite is used for completed past actions with a specific timeframe. Regular endings are added to the stem, but watch for spelling changes (llegar > llegué) and strong preterites (tener > tuve, poner > puse, hacer > hice). 简单过去时用于在特定时间范围内完成的过去动作。规则词尾加在词干上，但需注意拼写变化（llegar > llegué）和强变化形式（tener > tuve, poner > puse, hacer > hice）。
The imperfect describes ongoing, habitual or descriptive past situations without indicating completion. Its regularity is notable — only ‘ir’, ‘ser’ and ‘ver’ are irregular. 过去未完成时描述持续、习惯性或描述性的过去情况，不表明动作是否完成。其时态变化非常规则——只有 ‘ir’、’ser’ 和 ‘ver’ 是不规则形式。
The future simple (infinitive + -é, -ás, -á…) and the conditional (infinitive + -ía, -ías…) share the same irregular stems: tendr-, vendr-, dir-, habr- and others. Both convey probability and nuanced hypothesis. 将来未完成时（动词不定式 + -é, -ás, -á…）和条件式（动词不定式 + -ía, -ías…）共享相同的不规则词干，如 tendr-、vendr-、dir-、habr- 等。两者均可表达推测和细腻的假设。
Compound tenses such as the present perfect (he hablado) and pluperfect (había hablado) are formed with the auxiliary ‘haber’ and a regular past participle ending in -ado/-ido. Note the common irregular participles: hecho, dicho, vuelto, escrito. 复合时态如现在完成时（he hablado）和过去完成时（había hablado）由助动词 ‘haber’ 和以 -ado/-ido 结尾的规则过去分词构成。注意常见的不规则过去分词：hecho、dicho、vuelto、escrito。
2. Preterite vs Imperfect: Aspect and Triggers | 简单过去时与过去未完成时：体貌与触发词
Preterite signals actions perceived as completed: ‘Ayer comí paella.’ The imperfect focuses on the context or ongoing nature: ‘Cuando era niño, comía paella todos los domingos.’ 简单过去时表示被视为完成的动作：”Ayer comí paella（昨天我吃了海鲜饭）。” 过去未完成时侧重于背景或动作的延续性：”Cuando era niño, comía paella todos los domingos（我小的时候每周日都吃海鲜饭）。”
Time markers provide reliable clues. Preterite triggers include ‘ayer’, ‘la semana pasada’, ‘de repente’, ‘en 2010’. Imperfect triggers include ‘siempre’, ‘cada día’, ‘mientras’, ‘de joven’. 时间标志词提供可靠线索。简单过去时的触发词包括 ‘ayer’、’la semana pasada’、’de repente’、’en 2010’。过去未完成时的触发词包括 ‘siempre’、’cada día’、’mientras’、’de joven’。
When narrating a story, the imperfect sets the scene (weather, age, feelings) and the preterite advances the plot (main events). Mastering this interplay is critical for Paper 3 narratives. 在叙述故事时，过去未完成时用来设定场景（天气、年龄、感受），而简单过去时推动情节发展（主要事件）。掌握两者的交替使用对试卷三的叙事写作至关重要。
3. The Present Subjunctive: Forms and Uses | 现在虚拟语气：构成与用法
The present subjunctive is formed by taking the first-person singular of the present indicative, dropping the -o and adding opposite endings: -e for -ar verbs (hable) and -a for -er/-ir verbs (coma, viva). Irregulars follow familiar patterns: sea, vaya, sepa, dé. 现在虚拟语气由陈述式现在时第一人称单数去掉词尾 -o 并添加相反词尾构成：-ar 动词用 -e（hable），-er/-ir 动词用 -a（coma, viva）。不规则变化遵循已知模式：sea、vaya、sepa、dé。
It appears after expressions of desire (quiero que), doubt (dudo que), emotion (me alegra que), impersonal expressions (es importante que) and certain conjunctions like ‘para que’ and ‘a menos que’. 它用于表达愿望（quiero que）、怀疑（dudo que）、情感（me alegra que）、无人称句（es importante que）以及某些连词如 ‘para que’ 和 ‘a menos que’ 之后。
The subjunctive also follows ‘cuando’, ‘en cuanto’ and ‘hasta que’ when referring to future events: ‘Te llamaré cuando llegue.’ 当 ‘cuando’、’en cuanto’ 和 ‘hasta que’ 指将来事件时，也需用虚拟语气：”Te llamaré cuando llegue（我到了就给你打电话）。”
In relative clauses, the subjunctive describes an indefinite or non-existent antecedent: ‘Busco un libro que explique bien la gramática.’ 在关系从句中，当前行词不确定或不存在时使用虚拟语气：”我在找一本能够好好讲解语法的书。”
4. The Imperfect Subjunctive and ‘Si’ Clauses | 过去未完成虚拟语气与 ‘Si’ 条件句
The imperfect subjunctive is built from the third-person plural preterite minus -ron, plus the endings -ra or -se (hablara/hablase, comiera/comiese). Both forms are interchangeable in most contexts. 过去未完成虚拟语气由第三人称复数简单过去时去掉 -ron 再加词尾 -ra 或 -se 构成（hablara/hablase, comiera/comiese）。两种形式在多数语境中可互换。
It is triggered by the same structures as the present subjunctive but when the main verb is in a past tense: ‘Quería que vinieras.’ 触发条件与现在虚拟语气相同，但此时主句动词是过去时态：”他想让你来。”
The second conditional ‘si’ clause uses imperfect subjunctive in the condition and conditional in the result: ‘Si tuviera dinero, viajaría por el mundo.’ 第二类条件句中，条件部分用过去未完成虚拟语气，结果部分用条件式：”如果我有了钱，就会去周游世界。”
The third conditional refers to unreal past situations using pluperfect subjunctive (hubiera + participle) and conditional perfect: ‘Si hubiera estudiado, habría aprobado.’ 第三类条件句指非现实的过去情况，使用过去完成虚拟语气（hubiera + 分词）和条件完成式：”如果当时我学习了，本来是会通过的。”
5. The Imperative Mood: Commands | 命令式：命令与请求
Affirmative ‘tú’ commands usually take the third-person singular present indicative form: ‘Habla’, ‘Come’, ‘Escribe’. Negative ‘tú’ commands use the present subjunctive ‘tú’ form: ‘No hables’, ‘No comas’. 肯定 ‘tú’ 命令式通常使用陈述式现在时第三人称单数形式：’Habla’、’Come’、’Escribe’。否定 ‘tú’ 命令式则用现在虚拟语气 ‘tú’ 形式：’No hables’、’No comas’。
‘Usted’ and ‘ustedes’ commands always adopt the corresponding subjunctive form: ‘Hable’, ‘Coman’. Formal commands are essential for polite discourse. ‘Usted’ 与 ‘ustedes’ 命令式始终采用对应的虚拟语气形式：’Hable’、’Coman’。正式命令式是礼貌交流中的必备要素。
‘Vosotros’ affirmative drops -r of the infinitive and adds -d: ‘Hablad’, ‘Comed’. The negative uses the subjunctive: ‘No habléis’. ‘Vosotros’ 肯定式去掉不定式词尾 -r 再加上 -d：’Hablad’、’Comed’。否定式用虚拟语气：’No habléis’。
Object pronouns are attached to affirmative commands forming one word (Dímelo) but placed before negative commands (No me lo digas). Accent marks are often needed to preserve stress. 宾格代词附在肯定命令式词尾构成一个词（Dímelo），但放在否定命令式之前（No me lo digas）。往往需要加重音符号以保持重音位置。
6. Object and Reflexive Pronouns: Placement Rules | 宾格与自复代词：位置规则
Direct object pronouns (lo, la, los, las) replace the noun that directly receives the action. Indirect object pronouns (le, les) indicate to whom or for whom an action is done. 直接宾语代词（lo、la、los、las）替换直接接受动作的名词。间接宾语代词（le、les）指明动作所作的间接对象。
When both appear together, the indirect pronoun ‘le’ or ‘les’ changes to ‘se’ before the direct pronoun: ‘Se lo di’ (not le lo). The order is always se + indirect + direct + conjugated verb. 当两者同时出现时，间接宾语代词 ‘le’ 或 ‘les’ 在直接宾语代词前变为 ‘se’：”Se lo di（我把它给他了）”而非 le lo。顺序永远是 se + 间接宾语 + 直接宾语 + 变位动词。
Reflexive pronouns (me, te, se, nos, os, se) indicate the subject performs the action on itself. They follow the same placement rules as other object pronouns. 自复代词（me、te、se、nos、os、se）表示主语对自己发出的动作。它们的放置规则与其他宾格代词相同。
With infinitives and gerunds, pronouns can either be placed before the conjugated verb or attached to the non-finite form: ‘Lo voy a hacer’ = ‘Voy a hacerlo’. In written Pre-U essays, varying placement shows syntactic range. 与不定式和副动词连用时，代词既可放在变位动词前，也可附在非人称形式后：”Lo voy a hacer” 等于 “Voy a hacerlo”。在 Pre-U 作文中，灵活变换位置能展现句法广度。
