1. Regular Present Tense Conjugation | 规则动词现在时变位
Regular verbs follow three blueprint patterns according to their infinitive ending: -ar, -er, -ir. Remove the ending to find the stem, then attach the appropriate present-tense ending for the subject. This simple substitution formula is the foundation for all other tenses.
规则动词根据原形词尾 -ar、-er、-ir 分为三类变换蓝图。去掉词尾得到词干，再根据主语添加相应的现在时词尾。这个简单的替换公式是所有其他时态的基础。
| Subject | -ar (hablar) | -er (comer) | -ir (vivir) |
|---|---|---|---|
| yo | hablo | como | vivo |
| tú | hablas | comes | vives |
| él/ella/usted | habla | come | vive |
| nosotros/as | hablamos | comemos | vivimos |
| vosotros/as | habláis | coméis | vivís |
| ellos/ellas/ustedes | hablan | comen | viven |
Formula: stem + ending. The -ar endings are o, as, a, amos, áis, an. The -er endings are o, es, e, emos, éis, en. The -ir endings are o, es, e, imos, ís, en. Notice that -er and -ir differ only in the nosotros and vosotros forms.
公式：词干 + 词尾。-ar 词尾为 o, as, a, amos, áis, an。-er 词尾为 o, es, e, emos, éis, en。-ir 词尾为 o, es, e, imos, ís, en。注意 -er 和 -ir 仅在 nosotros 和 vosotros 形式上不同。
2. Key Irregular Present Verbs | 关键不规则动词现在时
Some of the most commonly used verbs do not follow the regular patterns. For the CAIE exam, you must memorise these as stand-alone formulas, especially ser, estar, ir, tener, and hacer. Treat each as its own unique ‘lexical rule’.
一些最常用的动词并不遵循规则变位。对于 CAIE 考试，你必须将这组动词作为独立公式来记忆，特别是 ser、estar、ir、tener 和 hacer。把每个动词视为自己独有的“词汇规则”。
| Subject | ser | estar | ir | tener | hacer |
|---|---|---|---|---|---|
| yo | soy | estoy | voy | tengo | hago |
| tú | eres | estás | vas | tienes | haces |
| él/ella/usted | es | está | va | tiene | hace |
| nosotros/as | somos | estamos | vamos | tenemos | hacemos |
| vosotros/as | sois | estáis | vais | tenéis | hacéis |
| ellos/ellas/ustedes | son | están | van | tienen | hacen |
Irregularities often involve stem changes (tener > tien-) or first-person endings (-oy, -go). Knowing these high-frequency forms is a non-negotiable foundation for Year 12 Spanish.
不规则性通常涉及词干变化（tener > tien-）或第一人称词尾（-oy、-go）。掌握这些高频形式是 Year 12 西班牙语不容商量的基础。
3. Present Perfect Formula | 现在完成时公式
The pretérito perfecto compuesto is formed with the present tense of the auxiliary verb haber plus a past participle. The participle formula depends on the verb class: -ar → -ado, -er/-ir → -ido.
现在完成时由助动词 haber 的现在时加上过去分词构成。分词的公式取决于动词类别：-ar → -ado，-er/-ir → -ido。
he / has / ha / hemos / habéis / han + [past participle]
Examples: He hablado (I have spoken), Has comido (You have eaten), Han vivido (They have lived). Some participles are irregular, such as visto (ver), escrito (escribir), hecho (hacer), dicho (decir), roto (romper), vuelto (volver). These must be memorised.
例如：He hablado（我说过了），Has comido（你吃过了），Han vivido（他们住过了）。有些分词是不规则的，如 visto（ver）、escrito（escribir）、hecho（hacer）、dicho（decir）、roto（romper）、vuelto（volver）。这些需要单独记忆。
4. Preterite vs Imperfect Decision Formula | 简单过去时与过去未完成时的选择公式
Choosing between the preterite (pretérito indefinido) and imperfect (pretérito imperfecto) trips up many learners. Use this decision framework: preterite for completed actions with clear boundaries, a chain of events, or interruptions; imperfect for ongoing/background actions, habitual past routines, descriptions, and time/age in the past.
在简单过去时和过去未完成时之间做选择难倒了许多学习者。使用这个决策框架：简单过去时用于有明确界限的完成动作、一连串事件或打断；过去未完成时用于持续/背景动作、过去的习惯性常事、描述以及过去的时间/年龄。
| Signal / Context | Use Preterite | Use Imperfect |
|---|---|---|
| Complete action | Estudié toda la noche. | Estudiaba mientras sonaba la música. |
| Habit in the past | – | Siempre íbamos al parque. |
| Interruption | Llamó cuando dormía. | Dormía cuando llamó. |
| Descriptions | – | La casa era azul y tenía un jardín. |
Formula: Is it a ‘photo’ (preterite) or a ‘video backdrop’ (imperfect)? Preterite signals: de repente, ayer, la semana pasada, una vez. Imperfect signals: siempre, cada día, de niño, mientras, los sábados.
公式：是“照片”（简单过去时）还是“视频背景”（过去未完成时）？简单过去时信号词：de repente、ayer、la semana pasada、una vez。过去未完成时信号词：siempre、cada día、de niño、mientras、los sábados。
5. Regular Preterite Conjugation Formula | 规则动词简单过去时变位公式
The preterite endings also follow a stem + ending pattern. The endings are distinctly different from the present tense and must be drilled until automatic.
简单过去时的词尾也遵循词干+词尾的模式。这些词尾与现在时截然不同，必须练习到自动反应的程度。
| Subject | -ar (hablar) | -er / -ir (comer / vivir) |
|---|---|---|
| yo | hablé | comí / viví |
| tú | hablaste | comiste / viviste |
| él/ella/usted | habló | comió / vivió |
| nosotros/as | hablamos | comimos / vivimos |
| vosotros/as | hablasteis | comisteis / vivisteis |
| ellos/ellas/ustedes | hablaron | comieron / vivieron |
Note that the nosotros form of -ar and -ir preterite is the same as the present tense (hablamos, vivimos). In writing, accent marks on yo (hablé) and él (habló) are essential for meaning and marks.
注意，-ar 和 -ir 的 nosotros 形式与现在时相同（hablamos、vivimos）。在写作中，重音符号在 yo（hablé）和 él（habló）上对于区分时态和得分至关重要。
6. Future and Conditional Simple Formulas | 将来时与条件式简单公式
The future and conditional tenses are among the easiest to form because they attach endings directly to the full infinitive (or to an irregular stem). The same set of endings works for -ar, -er, and -ir verbs, creating a highly predictable formula.
将来时与条件式是最容易构成的时态之一，因为它们把词尾直接加在整个动词原形（或不规则词干）上。同一组词尾适用于 -ar、-er 和 -ir 动词，形成一个高度可预测的公式。
Future: infinitive + é, ás, á, emos, éis, án
Conditional: infinitive + ía, ías, ía, íamos, íais, ían
Examples: hablaré (I will speak), comerías (you would eat), vivirán (they will live). A handful of verbs use modified stems (tener → tendr-, salir → saldr-, decir → dir-, hacer → har-, etc.) but attach the same endings. Memorising these 12 irregular stems is a powerful exam shortcut.
例如：hablaré（我将说话），comerías（你会吃），vivirán（他们将生活）。少数动词使用变形词干（tener → tendr-、salir → saldr-、decir → dir-、hacer → har- 等），但附加同样的词尾。记住这 12 个不规则词干是一个强大的考试捷径。
7. Present Subjunctive Formation Formula | 虚拟式现在时构成公式
The present subjunctive appears regularly in Year 12 expressing wishes, doubt, emotions, and after certain conjunctions. Its formation is simple: start with the yo form of the present indicative, drop the -o, and add the ‘opposite’ vowel endings.
虚拟式现在时频繁出现在 Year 12 课程中，用于表达愿望、怀疑、情感以及在某些连词之后。其构成很简单：从陈述式现在时的 yo 形式出发，去掉 -o，然后添加“相反”的元音词尾。
yo (present indicative) – o + subjunctive endings
For -ar verbs: hable, hables, hable, hablemos, habléis, hablen. For -er/-ir verbs: coma, comas, coma, comamos, comáis, coman; viva, vivas, viva, vivamos, viváis, vivan.
对于 -ar 动词：hable, hables, hable, hablemos, habléis, hablen。对于 -er/-ir 动词：coma, comas, coma, comamos, comáis, coman; viva, vivas, viva, vivamos, viváis, vivan。
Irregular verbs that have an irregular yo form keep that stem: tenga (from tengo), diga (from digo), conozca (from conozco). The six truly irregular subjunctives (sea, esté, vaya, sepa, dé, haya) must be learned by heart.
具有不规则 yo 形式的动词保留其词干：tenga（来自 tengo）、diga（来自 digo）、conozca（来自 conozco）。六个完全不受此规则约束的虚拟式（sea, esté, vaya, sepa, dé, haya）则需要熟记。
8. Affirmative and Negative Command Formulas | 肯定与否定命令式公式
Commands (imperatives) are essential for everyday communication and often tested in role-plays. The formation depends on whether the command is affirmative or negative, and on the subject (tú, usted, vosotros, ustedes).
命令式对于日常交流至关重要，常出现在角色扮演类考题中。其构成取决于命令是肯定还是否定，以及主语（tú、usted、vosotros、ustedes）。
| Form | Affirmative formula | Negative formula |
|---|---|---|
| tú | 3rd person singular present (habla, come, vive) | no + present subjunctive tú form (no hables) |
| usted | present subjunctive 3rd person sing. (hable) | no + present subjunctive (no hable) |
| vosotros | replace -r of infinitive with -d (hablad, comed, vivid) | no + present subjunctive vosotros (no habléis) |
| ustedes | present subjunctive 3rd person plural (hablen) | no + present subjunctive (no hablen) |
Pronouns are attached to the end of affirmative commands (dímelo, levántate) but placed before negative commands (no me lo digas, no te levantes). This word-order formula is a frequent source of marks in writing and speaking.
代词在肯定命令式中附着在动词末尾（dímelo、levántate），但在否定命令式中须前置（no me lo digas、no te levantes）。这个语序公式在写作和口语中常是得分点。
9. Pronoun Placement Rules | 代词位置规则
Object pronouns (me, te, lo/la, nos, os, los/las) and reflexive pronouns follow a strict order when combined. The formula is: se + 2nd-person indirect + 1st-person indirect + direct + verb. Only two pronouns are allowed per verb cluster, and le/les change to se before lo/la/los/las.
宾语代词（me、te、lo/la、nos、os、los/las）和自复代词在组合时遵循严格顺序。公式是：se + 第二人称间接 + 第一人称间接 + 直接 + 动词。每个动词簇最多允许两个代词，且 le/les 在 lo/la/los/las 前要变为 se。
Example: Se lo dije (I said it to him/her/them). With infinitives and gerunds, pronouns can either precede the conjugated verb or be attached to the end: Voy a comprarlo = Lo voy a comprar. Estoy leyéndolo = Lo estoy leyendo. Consistent application of this placement formula avoids clumsy repetition and raises sophistication.
例如：Se lo dije（我对他/她/他们说了这事）。与不定式和副动词连用时，代词既可放在变位动词前，也可附着在末尾：Voy a comprarlo = Lo voy a comprar。Estoy leyéndolo = Lo estoy leyendo。连贯使用这个位置公式能避免笨拙重复，提升表达的复杂度。
10. Comparatives and Superlatives | 比较级与最高级公式
Comparisons in Spanish use a small set of fixed structures that can be learned as templates. The core formulas are más/menos + adjective/adverb + que (more/less … than) and tan + adjective/adverb + como (as … as). For nouns, use tanto/a/os/as + noun + como.
西班牙语的比较使用一套固定的结构，可以像模板一样学习。核心公式是 más/menos + 形容词/副词 + que（比…更/更不）以及 tan + 形容词/副词 + como（和…一样）。比较名词时，用 tanto/a/os/as + 名词 + como。
más/menos + adj/adv + que
tan + adj/adv + como
tanto/a/os/as + noun + como
Irregular comparatives: mayor (older), menor (younger), mejor (better), peor (worse). Superlatives use el/la/los/las + más/menos + adjective (+ de): la más alta de la clase.
不规则比较级：mayor（更年长）、menor（更年轻）、mejor（更好）、peor（更差）。最高级用 el/la/los/las + más/menos + 形容词 (+ de)：la más alta de la clase。
11. Core Connective Frameworks | 核心连接词框架
Strong writing in Year 12 Spanish requires cohesive devices that act as logical formulas. Use these starters to structure arguments and narratives: Aunque + indicative/subjunctive (although), Por un lado… por otro lado… (on one hand… on the other…), No solo… sino también… (not only… but also…), Sin embargo, … (however), Dado que… (given that…), Por lo tanto, … (therefore).
Year 12 西班牙语的有力写作需要衔接手段，它们就像逻辑公式。使用这些开头词来组织论证和叙述：Aunque + 陈述式/虚拟式（虽然），Por un lado… por otro lado…（一方面…另一方面…），No solo… sino también…（不仅…而且…），Sin embargo, …（然而），Dado que…（鉴于…），Por lo tanto, …（因此）。
Complex sentence blueprint: [opinion] + porque + [reason] + y por eso + [consequence]. Substituting porque with ya que or puesto que adds variety. Using the subjunctive after expressions like es importante que, dudo que, no creo que is a reliable way to demonstrate advanced grammar.
复杂句蓝图：[观点] + porque + [原因] + y por eso + [结果]。用 ya que 或 puesto que 代替 porque 可以增加多样性。在 es importante que、dudo que、no creo que 等表达后使用虚拟式，是展示高级语法的可靠方式。
12. Agreement and Gender Number Rules | 一致性与性数规则
Every noun-adjective combination in Spanish follows a predictable agreement formula. The final vowel of the adjective must match the gender and number of the noun. For nouns ending in -o/-a, the pattern is straightforward; for -e or consonant endings, the adjective often adds -es for plural but does not change for gender.
西班牙语中每个名词与形容词的组合都遵循可预测的一致公式。形容词的最后一个元音必须与名词的性和数一致。对于以 -o/-a 结尾的名词，模式是直接的；对于以 -e 或辅音结尾的名词，形容词通常在复数时加 -es，但不在性上变化。
Formula: article (el/la/los/las) + noun + adjective (o/a/os/as or e/es). Indefinite articles follow the same gender rule: un/una/unos/unas. Be careful with masculine nouns that look feminine (el problema, el día, el sistema) and feminine nouns starting with stressed a- that take the article el (el agua fría). These high-frequency exceptions are favourite exam targets.
公式：冠词 (el/la/los/las) + 名词 + 形容词 (o/a/os/as 或 e/es)。不定冠词遵循相同的性数规则：un/una/unos/unas。要小心看似阴性的阳性名词（el problema、el día、el sistema）以及以重读 a- 开头且使用冠词 el 的阴性名词（el agua fría）。这些高频例外是考试中的常见考点。
