1. The Gender Formula of Nouns | 名词阴阳性判定定理
In French, every noun has a gender – masculine or feminine. There is no absolute rule, but you can increase accuracy with the suffix theorem: nouns ending in -age, -ment, -eau, -phone, -scope, and -isme are usually masculine (le fromage, le gouvernement, le bateau). Nouns ending in -tion, -sion, -té, -ette, -ence, -ance, and -euse are typically feminine (la nation, la télévision, la liberté, la baguette). Memorise these high-frequency endings as if they were mathematical postulates.
法语中每个名词都有阴阳性之分。虽然没有绝对规律,但借助词尾定理可以提高判断准确率:以 -age、-ment、-eau、-phone、-scope 和 -isme 结尾的名词通常为阳性(如 le fromage、le gouvernement、le bateau);以 -tion、-sion、-té、-ette、-ence、-ance 和 -euse 结尾的名词多为阴性(如 la nation、la télévision、la liberté、la baguette)。把这些高频词尾当作数学公理来记忆。
2. The Article Convention Formula | 冠词配合公式
Definite articles (the) : le + masculine singular, la + feminine singular, l’ + vowel or silent h, les + plural. Indefinite articles (a/an/some) : un + masculine, une + feminine, des + plural. Partitive articles (some/any) : du + masculine, de la + feminine, de l’ + vowel/h, des + plural. After a negative, these partitives and indefinites shrink to de or d’ : je n’ai pas de pain. Treat this transformation as a zeroing rule: negation deletes the quantity marker.
定冠词:le + 阳性单数,la + 阴性单数,l’ + 元音或哑音 h,les + 复数。不定冠词:un + 阳性,une + 阴性,des + 复数。部分冠词:du + 阳性,de la + 阴性,de l’ + 元音/h,des + 复数。在否定句中,部分冠词和不定冠词收缩为 de 或 d’,例如 je n’ai pas de pain。将此转化视为归零规则:否定消除数量标记。
3. Adjective Position & Agreement Theorem | 形容词位置与配合定理
Most French adjectives follow the noun: une voiture rouge. However, the BAGS group (Beauty, Age, Goodness, Size) usually precedes the noun: un beau garçon, un vieux livre, une bonne idée, une grande maison. All adjectives must agree in gender and number: add -e for feminine, -s for plural, -es for feminine plural. If the masculine form already ends in -e, it remains unchanged in the feminine (un élève timide → une élève timide). Irregular adjectives follow their own pattern: beau → belle, vieux → vieille, bon → bonne. Think of agreement as a symmetry principle that aligns the adjective with its noun.
多数法语形容词置于名词之后:une voiture rouge。但 BAGS 类(美丑、年龄、好坏、大小)形容词通常前置:un beau garçon、un vieux livre、une bonne idée、une grande maison。所有形容词必须与名词性数一致:阴性加 -e,复数加 -s,阴性复数加 -es。若阳性形式本身以 -e 结尾,则阴性不变(un élève timide → une élève timide)。不规则形容词遵循自身变化,如 beau → belle、vieux → vieille、bon → bonne。把配合视为一种使形容词与名词对齐的对称原则。
4. Present Tense Conjugation Law for Regular Verbs | 规则动词现在时变位定律
All regular -er verbs (except aller) follow this stem + ending formula: je stem + e, tu stem + es, il/elle stem + e, nous stem + ons, vous stem + ez, ils/elles stem + ent. For -ir verbs like finir (the -iss- type): je finis, tu finis, il finit, nous finissons, vous finissez, ils finissent. For -re verbs like vendre: je vends, tu vends, il vend, nous vendons, vous vendez, ils vendent. The endings are like a periodic table of the language; once memorised, you can conjugate thousands of verbs.
所有规则 -er 动词(除 aller 外)遵循“词干 + 词尾”公式:je 词干 + e,tu 词干 + es,il/elle 词干 + e,nous 词干 + ons,vous 词干 + ez,ils/elles 词干 + ent。对于 finir 这类 -ir 动词(插入 -iss- 的类型):je finis,tu finis,il finit,nous finissons,vous finissez,ils finissent。对于 vendre 这类 -re 动词:je vends,tu vends,il vend,nous vendons,vous vendez,ils vendent。这些词尾犹如语言的周期表,一旦牢记,你就能变位成千上万的动词。
5. The Passé Composé Construction Theorem | 复合过去时构成定理
The passé composé is formed as: present tense of avoir or être + past participle. Most verbs use avoir; a group of ‘Dr & Mrs Vandertramp’ verbs and reflexive verbs use être. With être, the past participle agrees with the subject: elle est allée, nous sommes partis. The participle of regular -er verbs ends in -é, -ir verbs in -i, -re verbs in -u. The direct object agreement rule: when a preceding direct object is present, the past participle agrees with it (les pommes que j’ai mangées). This can be thought of as a conditional agreement that activates only when the object precedes the verb.
复合过去时的构成公式为:avoir 或 être 的现在时 + 过去分词。大多数动词使用 avoir;一部分称为“Dr & Mrs Vandertramp”的动词以及所有代词式动词使用 être。使用 être 时,过去分词需与主语性数配合:elle est allée,nous sommes partis。规则 -er 动词的过去分词以 -é 结尾,-ir 动词以 -i 结尾,-re 动词以 -u 结尾。直接宾语前置配合规则:当直接宾语位于动词之前时,过去分词需与之配合(les pommes que j’ai mangées)。这可以视为一种条件配合原则,仅在宾语前置时激活。
6. The Imperfect Tense Formation Rule | 未完成过去时构成规则
The imperfect stem is derived from the nous form of the present tense minus -ons. To this stem, add the endings: -ais, -ais, -ait, -ions, -iez, -aient. The only exception is être, whose stem is ét- (j’étais, tu étais, etc.). This tense describes ongoing, habitual, or descriptive past actions. Use it as the background tense in storytelling. Its formula is disarmingly simple: present-nous stem + imperfect endings.
未完成过去时的词干来自现在时 nous 形式去掉 -ons。在此基础上添加词尾:-ais、-ais、-ait、-ions、-iez、-aient。唯一的例外是 être,其词干为 ét-(j’étais、tu étais 等)。该时态用于描写进行中的、习惯性的或描述性的过去动作,在叙述中充当背景时态。其公式简单得出奇:现在时 nous 词干 + 未完成过去时词尾。
7. The Near and Simple Future Time Equations | 最近将来时与简单将来时方程
Near future (futur proche) : present tense of aller + infinitive. Example: je vais manger (I am going to eat). Simple future (futur simple) : infinitive (or irregular stem) + endings -ai, -as, -a, -ons, -ez, -ont. For -re verbs, drop the final -e before adding endings (vendre → je vendrai). Irregular stems include être (ser-), avoir (aur-), faire (fer-), aller (ir-), pouvoir (pourr-), voir (verr-). Treat the simple future stem as the ‘root of prediction’, which you then combine with the future endings.
最近将来时:aller 的现在时 + 动词不定式。例如:je vais manger(我将要吃)。简单将来时:动词不定式(或不规则词干) + 词尾 -ai、-as、-a、-ons、-ez、-ont。以 -re 结尾的动词需去掉末尾的 -e 再加词尾(vendre → je vendrai)。不规则词干包括 être(ser-)、avoir(aur-)、faire(fer-)、aller(ir-)、pouvoir(pourr-)、voir(verr-)。把简单将来时的词干视为“预测之根”,然后与将来时词尾组合即可。
8. The Conditional Mood Formula | 条件式构成公式
The conditional is used to express would, could, or should. Its formation mirrors the simple future, but with imperfect endings: future stem + -ais, -ais, -ait, -ions, -iez, -aient. For example, je voudrais (I would like), nous pourrions (we could). This pattern is easy once you know the future stems. The conditional also appears in si clauses for hypothetical situations: Si j’avais de l’argent, j’achèterais une voiture (imperfect in si clause, conditional in result clause). Think of it as the ‘would’ projection of the future stem.
条件式用于表达“会”“可能”或“应该”。其构成仿照简单将来时,但使用未完成过去时的词尾:将来时词干 + -ais、-ais、-ait、-ions、-iez、-aient。例如:je voudrais(我想要),nous pourrions(我们可以)。一旦掌握了将来时词干,这个模式就很容易。条件式也出现在 si 引导的假设句中:Si j’avais de l’argent, j’achèterais une voiture(条件从句用未完成过去时,主句用条件式)。可将其视为将来时词干的“would 投射”。
9. The Subjunctive Trigger Theorem | 虚拟式触发定理
The subjunctive is not a tense but a mood used after expressions of wish, emotion, doubt, necessity, and certain conjunctions. The formula: que + subject + subjunctive form. Regular present subjunctive is formed from the ils/elles present stem + endings -e, -es, -e, -ions, -iez, -ent. Common irregulars: être (sois, sois, soit, soyons, soyez, soient), avoir (aie, aies, ait, ayons, ayez, aient), faire (fasse), pouvoir (puisse). Key triggers include il faut que, vouloir que, bien que, pour que, avant que, and expressions like je suis content que. When you encounter these, the subjunctive automatically engages, much like a trigger mechanism in physics.
虚拟式并非时态而是一种语式,用于表示愿望、情感、怀疑、必要性以及某些连词之后。公式为:que + 主语 + 虚拟式形式。规则现在虚拟式由 ils/elles 现在时词干 + 词尾 -e、-es、-e、-ions、-iez、-ent 构成。常见不规则变化:être(sois, sois, soit, soyons, soyez, soient)、avoir(aie, aies, ait, ayons, ayez, aient)、faire(fasse)、pouvoir(puisse)。关键触发词包括 il faut que、vouloir que、bien que、pour que、avant que 以及 je suis content que 等表达。一旦遇到这些词,虚拟式便自动开启,就像物理学中的触发机制。
10. The Object Pronoun Sequencing Law | 宾语代词排序定律
In sentences with multiple object pronouns, the order follows a strict sequence: me/te/se/nous/vous → le/la/les → lui/leur → y → en. When a verb is in the imperative affirmative, the order changes: le/la/les → moi/toi/nous/vous → lui/leur → y → en, and hyphens link them (Donne-le-moi !). In negative imperatives, regular order resumes. This fixed chain is non-negotiable; if you swap the positions, the sentence becomes ungrammatical. Memorising this sequence is like learning a chemical formula.
在包含多个宾语代词的句子中,顺序严格固定:me/te/se/nous/vous → le/la/les → lui/leur → y → en。在肯定命令式中顺序改变:le/la/les → moi/toi/nous/vous → lui/leur → y → en,并用连字符连接(Donne-le-moi !)。否定命令式则恢复常规顺序。这一固定链条不容颠倒,一旦调换位置,句子便不合语法。记住此序列如同背诵化学分子式。
11. The Negation Sandwich Structure | 否定式夹层结构
Standard negation wraps the conjugated verb: ne + verb + pas. In compound tenses, ne and pas surround the auxiliary verb (je n’ai pas mangé). Other negative expressions replace pas: ne … jamais (never), ne … plus (no longer), ne … rien (nothing), ne … personne (no one, after verb or at end), ne … que (only, meaning restriction). When two verbs are used, ne … pas encloses the first conjugated verb: je n’aime pas danser. Treat these as a pair of brackets that encapsulate the relevant verb or auxiliary.
标准否定式包裹变位动词:ne + 动词 + pas。在复合时态中,ne 和 pas 围绕助动词(je n’ai pas mangé)。其他否定表达替换 pas:ne … jamais(从不),ne … plus(不再),ne … rien(没什么),ne … personne(没有人,位于动词之后或句末),ne … que(仅仅,表限制)。当使用两个动词时,ne … pas 包围第一个变位动词:je n’aime pas danser。这些可视为一对括号,将相关动词或助动词裹在其中。
12. The Interrogative Conversion Formulas | 疑问句转换公式
There are three main ways to form questions in French. Formula 1 – Intonation: keep the statement word order and raise pitch at the end (Tu aimes le chocolat ?). Formula 2 – Est-ce que: insert est-ce que before the subject-verb sequence (Est-ce que tu aimes le chocolat ?). Formula 3 – Inversion: invert subject and verb, hyphenating (Aimes-tu le chocolat ?). When the inverted form would place two vowels together, insert -t- for euphony (A-t-il un stylo ?). Interrogative words (où, quand, comment, pourquoi, qui, que) can precede est-ce que or inversion: Où est-ce que tu vas ? / Où vas-tu ?. Each formula has its own level of formality, with inversion being the most formal.
法语疑问句主要有三种构成方式。公式一:语调法——保持陈述句语序,末尾升调(Tu aimes le chocolat ?)。公式二:est-ce que 法——在主语-动词序列前插入 est-ce que(Est-ce que tu aimes le chocolat ?)。公式三:倒装法——主语和动词倒装并加连字符(Aimes-tu le chocolat ?)。若倒装后两个元音相碰,插入 -t- 以求悦耳(A-t-il un stylo ?)。疑问词(où, quand, comment, pourquoi, qui, que)可置于 est-ce que 或倒装结构之前:Où est-ce que tu vas ? / Où vas-tu ?。每种公式具有不同的正式程度,倒装法最为正式。
