1. Present Tense Conjugation Formulas | 现在时变位公式

The present tense in Spanish is built on a predictable set of endings. For -AR verbs, take the stem and add -o, -as, -a, -amos, -áis, -an. For -ER verbs, add -o, -es, -e, -emos, -éis, -en. For -IR verbs, the endings are identical to -ER except for the nosotros and vosotros forms, which use -imos and -ís.

西班牙语现在时建立在一组可预测的词尾之上。对于 -AR 动词，取词干加 -o, -as, -a, -amos, -áis, -an。对于 -ER 动词，加 -o, -es, -e, -emos, -éis, -en。对于 -IR 动词，词尾除 nosotros 和 vosotros 用 -imos 和 -ís 外，其他与 -ER 一致。

Subject	Hablar (to speak)	Comer (to eat)	Vivir (to live)
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

Stem-changing verbs follow this same framework with a predictable vowel shift in certain persons. Think of it as a formula within a formula: in the present indicative, e → ie, o → ue, and e → i changes occur in all singular forms and the third-person plural, but not in nosotros or vosotros.

词干变化动词也遵循同一框架，但在某些人称会出现可预测的元音变换。可将此视为公式中的公式：在陈述式现在时中，e → ie、o → ue 以及 e → i 的变化出现在所有单数人称和第三人称复数中，nosotros 和 vosotros 除外。

2. The Preterite vs Imperfect Rule | 简单过去时与过去未完成时的使用规则

One of the most important distinctions in Spanish narrative is between the preterite (completed actions) and the imperfect (ongoing, habitual, or descriptive past). The rule can be summarised as: preterite for the main event, imperfect for the context.

西班牙语叙述中最重要的区别之一，是简单过去时（完成的动作）与过去未完成时（持续、习惯或描述性过去）之间的差异。该规则可概括为：主事件用简单过去时，背景用未完成时。

Preterite endings: -AR uses -é, -aste, -ó, -amos, -asteis, -aron. -ER and -IR share -í, -iste, -ió, -imos, -isteis, -ieron. Be aware of the accent marks; they are part of the formula.

简单过去时词尾：-AR 使用 -é, -aste, -ó, -amos, -asteis, -aron。-ER 和 -IR 共用 -í, -iste, -ió, -imos, -isteis, -ieron。注意重音符号，它们是公式的一部分。

Imperfect endings: -AR takes -aba, -abas, -aba, -ábamos, -abais, -aban. -ER and -IR both take -ía, -ías, -ía, -íamos, -íais, -ían. The formula holds without stem changes, except for the three irregulars: ir, ser, and ver.

过去未完成时词尾：-AR 取 -aba, -abas, -aba, -ábamos, -abais, -aban。-ER 和 -IR 均取 -ía, -ías, -ía, -íamos, -íais, -ían。这一公式没有词干变化，三个不规则动词除外：ir、ser 和 ver。

---

3. Future and Conditional Stem Formulas | 将来时与条件式的词干公式

The future and conditional tenses share a common logic: attach the endings directly to the infinitive. For the future, the endings are -é, -ás, -á, -emos, -éis, -án. For the conditional, add -ía, -ías, -ía, -íamos, -íais, -ían.

将来时和条件式共享同一逻辑：将词尾直接附加到动词原形上。将来时词尾为 -é, -ás, -á, -emos, -éis, -án。条件式加 -ía, -ías, -ía, -íamos, -íais, -ían。

However, a small set of high-frequency verbs uses irregular future/conditional stems. These can be remembered as altered infinitives: haber → habr-, poder → podr-, querer → querr-, saber → sabr-, poner → pondr-, salir → saldr-, tener → tendr-, venir → vendr-, decir → dir-, hacer → har-. The same endings apply.

然而，少量高频动词使用不规则将来/条件词干。可将其视作变形的原形形式：haber → habr-、poder → podr-、querer → querr-、saber → sabr-、poner → pondr-、salir → saldr-、tener → tendr-、venir → vendr-、decir → dir-、hacer → har-。同一套词尾仍然适用。

4. Perfect Tense Construction Formula | 完成时构成公式

All perfect tenses rely on the auxiliary verb haber plus a past participle. The present perfect formula is: [present of haber] + [-ado/-ido participle]. For example, ‘He hablado’ (I have spoken), ‘Has comido’ (You have eaten).

所有完成时都依赖助动词 haber 加过去分词。现在完成时的公式为：[haber 的现在时] + [-ado/-ido 分词]。例如，“He hablado”（我说过了），“Has comido”（你吃过了）。

The pluperfect uses the imperfect of haber: había/habías/había/habíamos/habíais/habían + past participle. The future perfect and conditional perfect follow the same pattern with future and conditional forms of haber.

过去完成时使用 haber 的过去未完成时：había、habías、había、habíamos、habíais、habían + 过去分词。将来完成时和条件完成式遵循同一模式，分别使用 haber 的将来时和条件式形式。

Irregular past participles must be memorised: abrir → abierto, cubrir → cubierto, decir → dicho, escribir → escrito, hacer → hecho, morir → muerto, poner → puesto, romper → roto, ver → visto, volver → vuelto.

不规则过去分词须记牢：abrir → abierto，cubrir → cubierto，decir → dicho，escribir → escrito，hacer → hecho，morir → muerto，poner → puesto，romper → roto，ver → visto，volver → vuelto。

5. The Present Subjunctive Derivation Formula | 现在虚拟式的推导公式

The present subjunctive is derived from the first-person singular of the present indicative. Remove the -o, then add the opposite vowel endings: for -AR verbs, use -e, -es, -e, -emos, -éis, -en. For -ER and -IR verbs, use -a, -as, -a, -amos, -áis, -an.

现在虚拟式由陈述式现在时的第一人称单数推导而来。去掉 -o，然后加上相反元音的词尾：-AR 动词用 -e, -es, -e, -emos, -éis, -en。-ER 和 -IR 动词用 -a, -as, -a, -amos, -áis, -an。

This formula automatically preserves stem changes that appear in the yo form. So ‘tengo’ (I have) yields ‘tenga, tengas, tenga, tengamos, tengáis, tengan’. This rule works for nearly all verbs except the fully irregular ones (ser, estar, ir, saber, haber, dar).

此公式会自动保留出现在 yo 形式中的词干变化。因此“tengo”（我有）产生“tenga, tengas, tenga, tengamos, tengáis, tengan”。该规则几乎适用于所有动词，只有完全不规则动词除外（ser、estar、ir、saber、haber、dar）。

6. The Subjunctive Trigger Formula | 虚拟式触发公式

The subjunctive is primarily triggered by a two-clause structure with a change of subject and a specific category of verbs in the main clause. The formula is: [Main clause expressing Wishes, Emotions, Impersonal expressions, Requests, Doubts, Ojalá] + que + [subjunctive].

虚拟式主要由包含主语变化的两分句结构触发，并且主句动词需属于特定范畴。公式为：[表达愿望、情感、无人称表达、要求、怀疑的主句或 Ojalá] + que + [虚拟式]。

WEIRDO is a useful acronym: Wishes (desear que), Emotions (alegrarse de que), Impersonal expressions (es importante que), Requests (pedir que), Doubts (dudar que), Ojalá. Remember that if there is no change of subject, the infinitive is usually used instead.

WEIRDO 是一个实用的首字母缩略词：Wishes (desear que)、Emotions (alegrarse de que)、Impersonal (es importante que)、Requests (pedir que)、Doubts (dudar que)、Ojalá。请记住，如果主语未发生变化，则通常使用动词原形。

7. Imperfect Subjunctive Derivation Formula | 过去虚拟式的推导公式

The imperfect subjunctive is derived from the third-person plural of the preterite. Take the ellos/ellas/ustedes form of the preterite, remove -ron, then add -ra, -ras, -ra, -ramos, -rais, -ran (or the -se variant).

过去虚拟式由简单过去时的第三人称复数推导而来。取 ellos/ellas/ustedes 的简单过去时形式，去掉 -ron，然后加上 -ra, -ras, -ra, -ramos, -rais, -ran（或 -se 变体）。

For example, ‘hablaron’ gives ‘hablara, hablaras, hablara, habláramos, hablarais, hablaran’. This formula ensures that all preterite stem irregularities are maintained in the imperfect subjunctive, making it elegantly consistent.

例如，“hablaron”推得“hablara, hablaras, hablara, habláramos, hablarais, hablaran”。此公式确保了所有简单过去时词干的不规则变化都在过去虚拟式中保留，使其优美地保持了一致性。

8. The ‘Si Clause’ Sequence Formulas | 条件句的时态搭配公式

Si clauses (if clauses) follow precise tense sequences that function like logical equations. First conditional: Si + [present indicative] → [future]. Second conditional: Si + [imperfect subjunctive] → [conditional]. Third conditional: Si + [pluperfect subjunctive] → [conditional perfect].

Si 从句遵循精确的时态搭配，如同逻辑等式。第一类条件句：Si + [陈述式现在时] → [将来时]。第二类条件句：Si + [过去虚拟式] → [条件式]。第三类条件句：Si + [过去完成虚拟式] → [条件完成式]。

Note that the present subjunctive never appears directly after ‘si’. A common exam trap is to insert a present subjunctive where an indicative is required. Keep the formula: ‘Si’ + present indicative = real, probable condition.

注意，虚拟式现在时决不会直接出现在“si”之后。一个常见的考试陷阱是在需要陈述式的地方插入虚拟式。请记住公式：“Si” + 陈述式现在时 = 真实、可能的条件。

9. Direct and Indirect Object Pronoun Placement Rules | 直接与间接宾语代词位置规则

In Spanish, object pronouns have two sentence positions, forming a syntactic formula. With a conjugated verb, pronouns go before the verb: [IO pronoun] + [DO pronoun] + [conjugated verb]. With an infinitive, gerund, or affirmative command, they attach to the end: [verb form] + [IO pronoun] + [DO pronoun].

西班牙语中，宾语代词在句子中有两种位置，构成一个句法公式。当动词为变位形式时，代词置于动词之前：[间接宾语代词] + [直接宾语代词] + [变位动词]。当遇到动词原形、副动词或肯定命令式时，代词附着在末尾：[动词形式] + [间接宾语代词] + [直接宾语代词]。

When both pronouns appear together, the indirect object pronoun (le, les) changes to ‘se’ before a third-person direct object pronoun (lo, la, los, las). This is a crucial morpho-phonetic rule: ‘Le lo’ is impossible in Spanish; it must be ‘Se lo’.

当两个代词同时出现时，间接宾语代词（le, les）在第三人称直接宾语代词（lo, la, los, las）之前变为“se”。这是一条重要的形态音位规则：“Le lo”在西班牙语中不可能出现，必须说“Se lo”。

10. Ser and Estar Distinction Formula | Ser 与 Estar 的区别公式

The choice between ser and estar can be reduced to a set of equations. Ser for permanent, defining characteristics, origin, time, and passive voice: [Noun/Pronoun] + ser + [inherent quality]. Estar for location, conditions, resulting states, and progressive constructions: [Noun/Pronoun] + estar + [condition/location].

Ser 与 Estar 的选择可归结为一组等式。Ser 用于永久性、定义性特征、起源、时间及被动语态：[名词/代词] + ser + [固有特质]。Estar 用于地点、状态、结果状态及进行式结构：[名词/代词] + estar + [状态/地点]。

Some adjectives change meaning with ser/estar: ser listo (to be clever), estar listo (to be ready); ser aburrido (to be boring), estar aburrido (to be bored). Treat these as distinct lexical equations that must be memorised.

某些形容词与 ser 或 estar 连用时意义会改变：ser listo（聪明），estar listo（准备好了）；ser aburrido（令人厌烦），estar aburrido（感到无聊）。请将它们视为必须记忆的独特词汇等式。

11. Por and Para Preposition Rules | 介词 Por 与 Para 的使用规则

Por and para both translate to ‘for’ in English, but their distribution follows a clear logical framework. Para expresses destination, purpose, deadline, recipient, and comparison: [action/object] + para + [goal/recipient]. Por expresses cause, duration, means, exchange, and motion through: [action/state] + por + [cause/medium].

Por 和 para 在英语中都可译为“for”，但其分布遵循清晰的逻辑框架。Para 表示目的地、目的、截止日期、接收者及比较：[动作/对象] + para + [目标/接收者]。Por 表示原因、持续时间、方式、交换及穿越的空间：[动作/状态] + por + [原因/媒介]。

A practical discrimination formula: if you can substitute ‘toward’ or ‘intended for’, use para. If you can substitute ‘through’ or ‘in exchange for’, use por. This heuristic resolves most exam questions.

一个实用的区分公式：若可替换为“朝向”或“旨在”，用 para。若可替换为“通过”或“作为交换”，用 por。这一启发式可解决大多数考试问题。

12. Accentuation and Stress Rules | 重音与重读规则

Spanish stress patterns are rule-governed. Words ending in a vowel, -n, or -s are stressed on the penultimate syllable and bear no written accent unless they break the rule. Words ending in a consonant other than -n or -s are stressed on the last syllable and carry no accent unless they break the rule. All exceptions must have a written accent over the stressed vowel.

西班牙语的重读模式由规则支配。以元音、-n 或 -s 结尾的单词重音落在倒数第二音节，除非违背规则，否则不加重音符号。以 -n 或 -s 之外的辅音结尾的单词重音落在最后一个音节，除非违背规则，否则不加重音符号。所有例外必须在重读元音上方标注重音符号。

This formula also explains why monosyllabic words generally carry no accent, except for diacritical accents distinguishing meaning (tú vs tu, él vs el, mí vs mi, sí vs si). The accent is a marker of deviation from the expected stress pattern.

这一公式也解释了单音节词一般不加注重音符号的原因，除非使用辨义重音以区分词义（tú 与 tu，él 与 el，mí 与 mi，sí 与 si）。重音符号是对预期重读模式偏离的标记。
