1. The Gender–Article Formula | 名词性别与冠词公式
A French noun always has a gender: masculine or feminine. The definite article (the) must agree in gender and number. The basic formula is: le + masculine singular noun, la + feminine singular noun, l' + singular noun starting with a vowel or silent h, les + plural noun (any gender).
法语名词永远带有性别:阳性或阴性。定冠词(相当于英语 the)必须在性和数上保持一致。基本公式为:le + 阳性单数名词,la + 阴性单数名词,l' + 以元音或不发音 h 开头的单数名词,les + 复数名词(不论性别)。
Indefinite articles follow a parallel pattern: un + masculine singular, une + feminine singular, des + plural. The partitive article 'some' also operates like a formula: du + masculine singular (de l' before vowel), de la + feminine singular, des + plural. Treat these as fixed templates; once you know a noun’s gender, you simply plug it into the correct slot.
不定冠词遵循平行模式:un + 阳性单数,une + 阴性单数,des + 复数。表示“一些”的部分冠词同样像公式一样运作:du + 阳性单数(元音前用 de l'),de la + 阴性单数,des + 复数。把这些视为固定模板;一旦你知道了名词的性别,只需将它填入正确的空位即可。
| Article type | Masculine | Feminine | Before vowel | Plural |
| Definite (the) | le | la | l' | les |
| Indefinite (a/an) | un | une | un/une | des |
| Partitive (some) | du (de l') | de la (de l') | de l' | des |
2. The Adjective Agreement Theorem | 形容词配合定理
Most French adjectives follow a simple agreement theorem: add -e for feminine, -s for masculine plural, and -es for feminine plural. The base form given in dictionaries is the masculine singular. Therefore, the ending transformation can be seen as a rule: If noun is feminine singular, attach -e; if masculine plural, attach -s; if feminine plural, attach -es.
多数法语形容词遵循一个简单的配合定理:阴性加 -e,阳性复数加 -s,阴性复数加 -es。字典中给出的基础形式是阳性单数。因此,词尾变换可以被视作一条规则:若名词为阴性单数,添加 -e;若为阳性复数,添加 -s;若为阴性复数,添加 -es。
Irregular adjectives also behave according to predictable patterns – these are the 'exception formulas'. For example, adjectives ending in -eux change to -euse in the feminine (heureux → heureuse), and those ending in -if become -ive (sportif → sportive). The common irregular beau, nouveau, vieux have special masculine forms before vowels (bel, nouvel, vieil). Think of these as special-case functions within the larger theorem.
不规则形容词也按照可预测的模式变化——这些就是“例外公式”。例如,以 -eux 结尾的形容词在阴性时变为 -euse(heureux → heureuse),以 -if 结尾的变为 -ive(sportif → sportive)。常见的不规则词 beau, nouveau, vieux 在元音前有特殊阳性形式(bel, nouvel, vieil)。将这些视为更大定理中的特殊情况函数。
The position of the adjective often follows the BAGS rule (Beauty, Age, Goodness, Size), which states that these types of adjectives usually come before the noun, while most others come after. This is a useful sorting formula: if adjective belongs to BAGS category, place before noun; otherwise, place after.
形容词的位置常常遵循 BAGS 规则(Beauty 美丽, Age 年龄, Goodness 好坏, Size 大小),即这类形容词通常放在名词之前,而其他大多数形容词放在名词之后。这是一条有用的排序公式:若形容词属于 BAGS 类别,则置于名词前;否则,置于名词后。
3. Present Tense Verb Conjugation – The Stem–Ending Equation | 现在时动词变位——词干–词尾等式
The present tense can be modelled as an equation: Verb = stem + ending. For regular -er verbs, remove -er to find the stem, then add: -e, -es, -e, -ons, -ez, -ent for je, tu, il/elle/on, nous, vous, ils/elles. Memorise this as a set of fixed endings that behave like constants in an algebraic expression.
现在时可以建模为一个等式:动词 = 词干 + 词尾。对于规则 -er 动词,去掉 -er 得到词干,然后为 je, tu, il/elle/on, nous, vous, ils/elles 分别加上:-e, -es, -e, -ons, -ez, -ent。把这组词尾当作代数表达式中的常量来记忆。
Regular -ir verbs (finir type) take the stem from the nous form minus -ons, and use the endings: -is, -is, -it, -issons, -issez, -issent. Regular -re verbs (vendre) use: -s, -s, -, -ons, -ez, -ent. The key is always: find the stem, then apply the ending set for that verb family.
规则 -ir 动词(finir 类)从 nous 形式减去 -ons 得到词干,使用词尾:-is, -is, -it, -issons, -issez, -issent。规则 -re 动词(vendre)使用:-s, -s, -, -ons, -ez, -ent。关键永远是:先找到词干,再套用该动词族的词尾集合。
The four most common irregular verbs – avoir, être, aller, faire – must simply be memorised as whole-word formulas, but even they display patterns that rhyme with regular endings (e.g. nous avons, vous avez align with -ons, -ez).
四个最常见的不规则动词——avoir, être, aller, faire——必须作为整体词汇公式来记忆,但即使它们也展现出与规则词尾押韵的模式(例如 nous avons, vous avez 与 -ons, -ez 对齐)。
4. The Near Future Formula | 最近将来时公式
To talk about something that is going to happen, French uses a construction almost identical to English: present tense of aller + infinitive of the main verb. This is a plug-and-play formula: conjugate aller according to the subject, then leave the main verb untouched in its infinitive form.
要表达即将发生的事情,法语使用一个几乎与英语相同的结构:aller 的现在时 + 主要动词的不定式。这是一条即插即用的公式:根据主语变位 aller,然后将主要动词以不定式形式原样保留。
For example, Je vais manger (I am going to eat), Tu vas finir (You are going to finish), Nous allons regarder (We are going to watch). Note that the infinitive does not change – it behaves as a constant in the structure.
例如,Je vais manger(我将要吃),Tu vas finir(你将完成),Nous allons regarder(我们将看)。注意不定式不发生变化——它在结构中充当常量。
5. The Perfect Tense Composition Formula | 复合过去时构成公式
The perfect tense (passé composé) is built using a two-part formula: auxiliary verb (avoir or être) in present tense + past participle of the main verb. This auxiliary–participle pair acts like a compound atom – both parts are necessary for the tense to be formed correctly.
复合过去时(passé composé)使用一个两部分公式来构建:助动词(avoir 或 être)的现在时 + 主要动词的过去分词。这一助动词–分词对就像复合原子——两部分必须同时存在才能正确构成该时态。
Most verbs use avoir. The past participle of regular -er verbs is formed by replacing -er with é (manger → mangé); -ir with i (finir → fini); -re with u avoir, the participle does not agree with the subject unless a direct object precedes it.
大多数动词使用 avoir。规则 -er 动词的过去分词是将 -er 替换为 é(manger → mangé);-ir 替换为 i(finir → fini);-re 替换为 u(vendre → vendu)。使用 avoir 时,过去分词不与主语配合,除非直接宾语位于其前。
A small group of verbs (often motion or state verbs) use être, and the past participle must agree with the subject in gender and number. The mnemonic DR MRS VANDERTRAMP helps recall these verbs. Add -e for feminine, -s for plural, -es for feminine plural to the participle.
一小部分动词(通常是运动或状态动词)使用 être,过去分词必须在性和数上与主语配合。助记口诀 DR MRS VANDERTRAMP 有助于记忆这些动词。给分词添加 -e 表示阴性,-s 表示复数,-es 表示阴性复数。
6. The Negation Sandwich Formula | 否定结构三明治公式
Basic negation in French wraps the verb in a 'sandwich': ne + verb + pas. The two parts surround the conjugated verb (or the auxiliary in compound tenses). In spoken French, the ne is often dropped, but in written and formal French it remains essential.
法语的基本否定将动词包裹在一个“三明治”中:ne + 动词 + pas。这两部分包围着变位动词(或复合时态中的助动词)。在口语中,ne 经常被省略,但在书面语和正式法语中,它仍然是必不可少的。
Other negative expressions follow the same sandwich pattern but replace pas with another word: ne... jamais (never), ne... plus (no longer), ne... rien (nothing), ne... personne (nobody), ne... que (only). In compound tenses, the second half usually goes after the auxiliary but before the past participle: Je n'ai pas mangé.
其他否定表达遵循同样的三明治模式,但将 pas 替换为另一个词:ne... jamais(从不),ne... plus(不再),ne... rien(没有什么),ne... personne(没有人),ne... que(仅仅)。在复合时态中,后一半通常放在助动词之后、过去分词之前:Je n'ai pas mangé。
7. Question Formation – Three Structural Options | 疑问句构建——三种结构选项
French offers three formulas for turning a statement into a question. The first and most formal is inversion: place the verb before the subject pronoun, linked by a hyphen, e.g. Parles-tu français? If a vowel clash occurs, insert -t-: A-t-il un chien?
法语提供三种将陈述句变为疑问句的公式。第一种也是最正式的是倒装:将动词置于主语代词之前,用连字符连接,例如 Parles-tu français? 如果出现元音冲突,则插入 -t-:A-t-il un chien?
The second option uses est-ce que before a normal statement: Est-ce que tu parles français? This is widely used in both spoken and written French and requires no word order change. Think of it as a question-introducing prefix.
第二种选项在正常陈述句前使用 est-ce que:Est-ce que tu parles français? 这种形式在口语和书面语中都被广泛使用,无需改变词序。可以把它看作疑问引入前缀。
The third, most informal method, simply raises intonation at the end of a statement: Tu parles français? All three are correct, and choosing among them depends on register and context.
第三种最不正式的方法只是在陈述句末尾提高语调:Tu parles français? 这三种形式都是正确的,选择哪种取决于语域和语境。
8. The Comparative and Superlative Structures | 比较级与最高级结构
Comparisons with adjectives follow the formula: plus/moins/aussi + adjective + que + compared noun. For example, Marie est plus grande que Luc. (Marie is taller than Luc). The adjective must still agree with the subject it describes.
形容词的比较遵循以下公式:plus/moins/aussi + 形容词 + que + 比较对象名词。例如,Marie est plus grande que Luc.(玛丽比卢克高)。形容词仍需与其描述的主语配合。
With nouns, use plus de/moins de/autant de + noun + que: J'ai plus de livres que toi. (I have more books than you). With verbs, the structure becomes verb + plus/moins/autant que: Il travaille plus que moi.
与名词搭配时,使用 plus de/moins de/autant de + 名词 + que:J'ai plus de livres que toi.(我的书比你多)。与动词搭配时,结构变为 动词 + plus/moins/autant que:Il travaille plus que moi.
The superlative follows a similar template: for adjectives, use le/la/les plus + adjective (or moins for least). With nouns, le plus de + noun. For example, C'est la fille la plus intelligente. (She is the most intelligent girl). The definite article must agree with the noun’s gender and number.
最高级遵循类似的模板:对于形容词,使用 le/la/les plus + 形容词(或 moins 表示最少)。对于名词,使用 le plus de + 名词。例如,C'est la fille la plus intelligente.(她是最聪明的女孩)。定冠词必须在性和数上与名词一致。
9. Direct Object Pronoun Placement Algorithm | 直接宾语代词位置算法
Direct object pronouns (me, te, le, la, nous, vous, les) replace nouns that receive the action directly. The placement rule is a strict algorithm: they go immediately before the conjugated verb (or before the auxiliary in compound tenses). In negative commands, they follow ne but remain before the verb.
直接宾语代词(me, te, le, la, nous, vous, les)替代直接接受动作的名词。位置规则是一条严格的算法:它们紧邻变位动词之前(或在复合时态中紧邻助动词之前)。在否定命令中,它们跟在 ne 之后,但仍然在动词之前。
For example: Je regarde la télé → Je la regarde. In the perfect tense: J'ai vu le film → Je l'ai vu. The object pronoun goes before the auxiliary ai. In a negative command: Ne me regarde pas! (Don't look at me!). The algorithm remains consistent: pronoun before main verb, after ne if present.
例如:Je regarde la télé → Je la regarde。在复合时态中:J'ai vu le film → Je l'ai vu。宾语代词位于助动词 ai 之前。在否定命令中:Ne me regarde pas!(别看我!)算法保持一致:代词在主动词之前,如果有 ne 则在其后。
10. The Possessive Adjective–Noun Agreement Law | 主有形容词–名词配合法则
Possessive adjectives (my, your, his/her, our, their) must agree with the noun they modify in gender and number, not with the possessor's gender. The formula is: choose the form based on the object owned. Mon, ton, son are used before masculine singular nouns and before feminine nouns starting with a vowel; ma, ta, sa before feminine singular nouns; mes, tes, ses before plural nouns.
主有形容词(我的、你的、他/她的、我们的、他们的)必须在性和数上与被修饰的名词一致,而不是与所有者的性别一致。公式是:基于被拥有物品的性别和数来选择形式。mon, ton, son 用于阳性单数名词前以及以元音开头的阴性名词前;ma, ta, sa 用于阴性单数名词前;mes, tes, ses 用于复数名词前。
For plural possessors: notre, votre, leur before singular nouns (both genders), and nos, vos, leurs before plural nouns. The key insight is that mon, ton, son are also used with feminine nouns starting with a vowel to avoid a vowel clash, which overwrites the usual feminine form – this is the 'elision exception' within the law.
对于复数所有者:notre, votre, leur 用于单数名词前(两种性别皆可),nos, vos, leurs 用于复数名词前。关键的理解是,mon, ton, son 也用于以元音开头的阴性名词前,以避免元音冲突,这会覆盖通常的阴性形式——这就是该法则中的“省音例外”。
11. The Imperative Mood – Truncated Ending Rule | 命令式——词尾截断规则
The imperative (used for giving orders or suggestions) is formed by using the tu, nous, and vous forms of the present tense, but with one important modification: for -er verbs, the final -s of the tu form is dropped (unless followed by the pronouns y or en for pronunciation). Thus, Tu parles becomes Parle!
命令式(用于下达命令或提出建议)由现在时的 tu、nous 和 vous 形式构成,但有一项重要的修改:对于 -er 动词,tu 形式的末尾 -s 被去掉(除非后面跟着代词 y 或 en 以便发音)。因此,Tu parles 变为 Parle!
For -ir and -re verbs, the tu form keeps its final -s: Finis! (Finish!), Vends! (Sell!). Negative commands place ne before the verb and pas after, and object pronouns move to before the verb: Ne le fais pas! (Don't do it!).
对于 -ir 和 -re 动词,tu 形式保留其末尾的 -s:Finis!(做完!),Vends!(卖掉!)。否定命令将 ne 放在动词前、pas 放在动词后,宾语代词移到动词之前:Ne le fais pas!(别做那件事!)。
12. Prepositions with Geographical Names – The Locative Theorem | 地理名词介词——定位定理
When talking about being in or going to a city, country, or region, French prepositions follow a predictable theorem based on gender and number. For cities, use à (to) and de (from): Je vais à Paris. / Je viens de Paris.
当谈论在某个城市、国家或地区,或者前往那里时,法语介词遵循一个基于性别和数的可预测定理。对于城市,使用 à(去)和 de(来自):Je vais à Paris. / Je viens de Paris.
For feminine countries (most ending in -e) or continents, use en for 'to' and 'in', and de for 'from' (with contraction if needed): Je vais en France. / Je viens de France. For masculine countries beginning with a consonant, use au (to) and du (from): Je vais au Canada. / Je viens du Canada. For plural countries, use aux and des: Je vais aux États-Unis. / Je viens des États-Unis.
对于阴性国家(多数以 -e 结尾)或大洲,使用 en 表示“去”和“在”,使用 de 表示“来自”(必要时缩合):Je vais en France. / Je viens de France. 对于以辅音开头的阳性国家,使用 au(去)和 du(来自):Je vais au Canada. / Je viens du Canada. 对于复数国家,使用 aux 和 des:Je vais aux États-Unis. / Je viens des États-Unis.
This theorem reduces what seems like arbitrary preposition choice to a simple decision tree based on the place name’s form. Memorising the gender of the country unlocks the correct preposition automatically.
这一定理将看似任意的介词选择简化为一个基于地名形式的简单决策树。记住了国家的性别,就能自动解锁正确的介词。
