本手册汇集了 Year 11 剑桥 IGCSE 西班牙语课程中最核心的语法模式、动词结构和用法“公式”。与其孤立地背诵单词，不如将这些规则视为在任何考试场景中（从写作到口语）都可以灵活套用的可靠方程。每一节都以公式形式呈现关键概念，配有清晰的例句和双语解释。
1. Regular Present-Tense Conjugation | 规则动词现在时变位公式
For regular verbs, remove the infinitive ending (-ar, -er, -ir) and add the following endings to the stem. Think of it as: STEM + PERSONAL ENDING = present-tense verb.
对于规则动词，去掉不定式词尾（-ar, -er, -ir），在词干上添加下列词尾。我们可以理解为：词干 + 人称词尾 = 现在时动词。
| Subject | -ar (hablar) | -er (comer) | -ir (vivir) |
|---|---|---|---|
| yo | -o: hablo | -o: como | -o: vivo |
| tú | -as: hablas | -es: comes | -es: vives |
| él/ella/usted | -a: habla | -e: come | -e: vive |
| nosotros/as | -amos: hablamos | -emos: comemos | -imos: vivimos |
| vosotros/as | -áis: habláis | -éis: coméis | -ís: vivís |
| ellos/ellas/ustedes | -an: hablan | -en: comen | -en: viven |
Notice that for all three groups, the ‘yo’ form ends in -o. For -er and -ir verbs, the endings are identical except for the ‘nosotros’ and ‘vosotros’ forms.
请注意，所有三组动词的“yo”形均以 -o 结尾。对于 -er 和 -ir 动词，除了“nosotros”和“vosotros”形式外，词尾完全相同。
2. Key Irregular Present Verbs | 核心不规则动词现在时公式
The most frequent verbs are irregular, so they must be learned as set patterns. Below are the essential ones, often forming the backbone of GCSE spoken and written tasks.
最常用的动词往往是不规则的，因此必须作为固定模式来学习。以下是核心不规则动词，它们常常是 GCSE 口语和写作任务的骨架。
| Subject | ser (to be) | estar (to be) | ir (to go) | tener (to have) | hacer (to do/make) |
|---|---|---|---|---|---|
| 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 |
Remember that ‘tener’ is stem-changing in the singular and 3rd-person plural (tengo, tienes, tiene, tienen), but regular in ‘nosotros’ and ‘vosotros’. This pattern appears frequently.
请记住，“tener”在单数和第三人称复数中发生词干变化（tengo, tienes, tiene, tienen），但在“nosotros”和“vosotros”形式中保持规则。这一模式出现频率极高。
3. Adjective Agreement Formula | 形容词一致性公式
Spanish adjectives must match the noun they describe in both gender and number. The basic formula is: ADJECTIVE ROOT + -o (masculine singular), -a (feminine singular), -os (masculine plural), -as (feminine plural).
西班牙语形容词必须与所修饰的名词在性和数上保持一致。基本公式为：形容词词根 + -o（阳性单数）、-a（阴性单数）、-os（阳性复数）、-as（阴性复数）。
For adjectives ending in -e or a consonant, the plural is formed by adding -s or -es, and there is no gender distinction: un chico inteligente → unos chicos inteligentes; una chica inteligente → unas chicas inteligentes.
对于以 -e 或辅音结尾的形容词，其复数形式通过添加 -s 或 -es 构成，且没有性的区分：un chico inteligente → unos chicos inteligentes；una chica inteligente → unas chicas inteligentes。
When using more than one adjective, the comma rule applies: un coche rojo y grande. However, before a masculine singular noun, the adjective ‘grande’ shortens to ‘gran’: un gran problema.
当使用多个形容词时，逗号规则适用：un coche rojo y grande。但是，在阳性单数名词前，形容词“grande”会缩短为“gran”：un gran problema。
4. Articles: Definite and Indefinite | 冠词公式：定冠词与不定冠词
Articles must agree with the noun’s gender and number. Learn them as two parallel sets of four formulas.
冠词必须与名词的性和数一致。请将它们作为两组并行的四公式来学习。
| Masculine | Feminine | |
|---|---|---|
| Singular Definite | el | la |
| Plural Definite | los | las |
| Singular Indefinite | un | una |
| Plural Indefinite | unos | unas |
Exception: feminine singular nouns beginning with stressed ‘a’ or ‘ha’ take the masculine article ‘el’ in singular, but remain feminine: el agua fría, las aguas frías.
例外情况：以重读的“a”或“ha”开头的阴性单数名词在单数形式中使用阳性冠词“el”，但其本身仍为阴性：el agua fría，las aguas frías。
Use the definite article when talking about things in general, with days of the week, and before titles. Omit it when the noun is a direct object of an indefinite amount.
在谈论一般事物时、在星期几之前以及在头衔之前使用定冠词。当名词是表示不定量的直接宾语时，则省略冠词。
5. Pronoun Patterns: Subject, Object, Reflexive | 代词公式：主格、宾格与反身代词
Pronouns replace nouns and have strict position rules. The subject pronouns are often omitted unless needed for clarity, but the others are essential for sentence structure.
代词用来替代名词，并有严格的位置规则。主格代词除非需要澄清，否则经常省略，但其他代词对句子结构至关重要。
| Subject | Direct Object | Indirect Object | Reflexive |
|---|---|---|---|
| yo | me | me | me |
| tú | te | te | te |
| él/ella/usted | lo/la | le | se |
| nosotros/as | nos | nos | nos |
| vosotros/as | os | os | os |
| ellos/ellas/ustedes | los/las | les | se |
The placement formula: (1) Before a conjugated verb: Te lo doy. (2) Attached to an infinitive or gerund: Voy a dárselo. (3) With positive commands, attached and often with an accent: Dámelo.
位置公式：(1) 位于变位动词之前：Te lo doy。(2) 附着于不定式或副动词之后：Voy a dárselo。(3) 用于肯定命令句时，附着于动词后并常添加重音：Dámelo。
6. Present Progressive Formula | 现在进行时公式
To express an action happening right now, use: ESTAR (conjugated) + GERUND. The gerund is formed by adding -ando to -ar stems and -iendo to -er/-ir stems.
要表达正在进行的动作，使用：ESTAR（变位）+ 副动词。副动词的构成：-ar 词干加 -ando，-er/-ir 词干加 -iendo。
Examples: Estoy estudiando para el examen. (I am studying for the exam.) — Ellos están comiendo en el restaurante. (They are eating in the restaurant.) Stem-changing -ir verbs also change in the gerund: dormir → durmiendo, pedir → pidiendo.
例句：Estoy estudiando para el examen.（我正在为考试而学习。）—— Ellos están comiendo en el restaurante.（他们正在餐厅吃饭。）词干变化的 -ir 动词在副动词形式中也会发生变化：dormir → durmiendo，pedir → pidiendo。
Note that the gerund does not change for gender or number; it remains invariable. Do not confuse this with the English ‘I am going’, which uses ‘ir a’ to express future.
请注意，副动词没有性和数的变化，形式始终不变。不要将其与英语的“I am going”混淆，后者使用“ir a”来表示将来。
7. Preterite (Simple Past) Regular Formula | 简单过去时规则变化公式
The preterite is used for completed actions in the past. The regular formula: STEM + PRETERITE ENDING. For -ar verbs, add: -é, -aste, -ó, -amos, -asteis, -aron. For -er and -ir verbs, add: -í, -iste, -ió, -imos, -isteis, -ieron.
简单过去时用于描述过去已经完成的动作。规则公式为：词干 + 简单过去时词尾。对于 -ar 动词，添加：-é, -aste, -ó, -amos, -asteis, -aron。对于 -er 和 -ir 动词，添加：-í, -iste, -ió, -imos, -isteis, -ieron。
Example: Ayer hablé con mi abuela. (Yesterday I spoke with my grandmother.) — Comieron paella en la fiesta. (They ate paella at the party.) The ‘nosotros’ form of -ar and -ir verbs is identical to the present tense, so time markers like ‘ayer’ or ‘anoche’ are crucial.
例句：Ayer hablé con mi abuela.（昨天我和祖母通了电话。）—— Comieron paella en la fiesta.（他们在聚会上吃了海鲜饭。）-ar 和 -ir 动词的“nosotros”形式与现在时相同，因此像“ayer”或“anoche”这样的时间标记至关重要。
Common irregular preterites include: tener → tuve, estar → estuve, hacer → hice, ir/ser → fui, decir → dije. These must be memorised as fixed patterns.
常见的不规则简单过去时包括：tener → tuve，estar → estuve，hacer → hice，ir/ser → fui，decir → dije。这些必须作为固定模式来记忆。
8. Imperfect Tense Formula | 未完成过去时公式
The imperfect describes ongoing, habitual or background actions in the past. The formula is formed by adding these endings to the stem: -ar verbs take -aba, -abas, -aba, -ábamos, -abais, -aban; -er and -ir verbs take -ía, -ías, -ía, -íamos, -íais, -ían.
未完成过去时描述过去正在进行、习惯性发生或作为背景的动作。其公式为：在词干上添加以下词尾：-ar 动词使用 -aba, -abas, -aba, -ábamos, -abais, -aban；-er 和 -ir 动词使用 -ía, -ías, -ía, -íamos, -íais, -ían。
Example: Cuando era niño, jugaba al fútbol todos los días. (When I was a child, I used to play football every day.) — Mientras leía, sonó el teléfono. (While I was reading, the phone rang.)
例句：Cuando era niño, jugaba al fútbol todos los días.（当我还是个孩子时，我每天都踢足球。）—— Mientras leía, sonó el teléfono.（当我正在读书时，电话响了。）
There are only three irregular verbs in the imperfect: ser (era, eras, era, éramos, erais, eran), ir (iba, ibas, iba, íbamos, ibais, iban) and ver (veía, veías, veía, veíamos, veíais, veían).
未完成过去时中只有三个不规则动词：ser（era, eras, era, éramos, erais, eran）、ir（iba, ibas, iba, íbamos, ibais, iban）和 ver（veía, veías, veía, veíamos, veíais, veían）。
9. Future and Conditional Formulas | 将来时与条件式公式
The future tense is formed by attaching the future endings directly to the full infinitive: INFINITIVE + -é, -ás, -á, -emos, -éis, -án. No stem is removed.
将来时的构成是将将来时词尾直接添加在整个不定式之后：不定式 + -é, -ás, -á, -emos, -éis, -án。无需去掉词干。
Example: Mañana lloverá en el norte. (Tomorrow it will rain in the north.) — Viajaré a España el próximo verano. (I will travel to Spain next summer.) The same endings are used for all -ar, -er and -ir verbs with a small set of irregular stems: tener → tendr-, salir → saldr-, hacer → har-, etc.
例句：Mañana lloverá en el norte.（明天北部地区将会下雨。）—— Viajaré a España el próximo verano.（明年夏天我将前往西班牙旅行。）所有 -ar、-er 和 -ir 动词都使用同样的词尾，只有一小部分不规则词干变化：tener → tendr-，salir → saldr-，hacer → har- 等。
The conditional uses the same irregular stems for these verbs, but the endings are: INFINITIVE + -ía, -ías, -ía, -íamos, -íais, -ían. Me gustaría visitar México. (I would like to visit Mexico.) It often expresses polite requests or hypothetical situations.
条件式对于这些动词使用相同的不规则词干，但词尾为：不定式 + -ía, -ías, -ía, -íamos, -íais, -ían。Me gustaría visitar México.（我想去墨西哥看看。）条件式常用来表达礼貌请求或假设情境。
10. Present Subjunctive Basics | 虚拟式现在时基础公式
The subjunctive mood appears in subordinate clauses expressing wishes, doubt, emotion or uncertainty. The formula: take the ‘yo’ form of the present indicative, drop the -o and add the opposite vowel endings: -er/-ir endings for -ar verbs and -ar endings for -er/-ir verbs.
虚拟式语气用于表达愿望、怀疑、情感或不确定性的从句中。其公式为：取现在时陈述式“yo”形，去掉 -o，然后添加相反的元音词尾：-ar 动词使用 -er/-ir 的词尾，-er/-ir 动词使用 -ar 的词尾。
Example: Quiero que tú hables con ella. (I want you to speak with her.) — Es importante que comamos verduras. (It is important that we eat vegetables.)
例句：Quiero que tú hables con ella.（我希望你和她谈谈。）—— Es importante que comamos verduras.（我们吃蔬菜很重要。）
Irregular subjunctive stems come from the ‘yo’ present indicative irregular: tener → tenga, hacer → haga, poner → ponga, salir → salga. The key trigger phrases include ‘para que’, ‘antes de que’, ‘es necesario que’ and ‘dudo que’.
虚拟式不规则词干来自现在时陈述式“yo”形的不规则变化：tener → tenga，hacer → haga，poner → ponga，salir → salga。关键的触发短语包括“para que”、“antes de que”、“es necesario que”和“dudo que”。
11. Object Pronoun Positioning Rules | 宾格代词位置规则
Mastering pronoun order is vital for fluency. The universal order when combining direct and indirect object pronouns is: INDIRECT + DIRECT + VERB. When both 3rd-person pronouns appear together, the indirect object ‘le’ or ‘les’ changes to ‘se’ for phonetic reasons.
掌握代词顺序对于流利表达至关重要。当同时使用与格和宾格代词时，通用的顺序为：与格 + 宾格 + 动词。当两个第三人称代词同时出现时，与格代词“le”或“les”出于语音原因会变为“se”。
Formula in action: Se lo di a Juan. (I gave it to Juan.) Here ‘se’ replaces ‘le’, and ‘lo’ is the book (direct object). The accent mark appears when attaching two pronouns to an infinitive or gerund, e.g., Diciéndoselo.
公式的实际运用：Se lo di a Juan.（我把它给了胡安。）这里的“se”代替了“le”，“lo”指书（直接宾语）。当将两个代词附着于不定式或副动词时，需要添加重音，例如：Diciéndoselo（正在告诉他这件事）。
With negative commands, pronouns go before the verb: No se lo digas. With positive commands, they attach to the end: Díselo.
在否定命令句中，代词位于动词之前：No se lo digas。在肯定命令句中，代词附着于动词词尾：Díselo。
12. Comparisons and Superlatives Formulas | 比较级与最高级公式
Comparatives follow clear formulas. To compare equality, use: tan + ADJECTIVE/ADVERB + como (as … as) or tanto/a/os/as + NOUN + como (as much/many … as). For inequality: más … que (more … than) or menos … que (less … than).
比较级遵循清晰的公式。比较同等程度时，使用：tan + 形容词/副词 + como（像……一样）或 tanto/a/os/as + 名词 + como（和……一样多）。比较不等程度时，使用：más … que（
