📚 IGCSE CIE German: Quick Reference to Key Formulas & Theorems | IGCSE CIE 德语:公式定理速查手册

In IGCSE CIE German, mastering the language can feel like solving a series of equations. Just as maths has its formulas and theorems, German grammar relies on fixed patterns, rules of word order, case endings, and verb structures that never change. This quick-reference handbook recasts the essential building blocks of German as 'formulas' and 'theorems' – clear, reliable rules you can memorise and apply in writing, speaking, listening, and reading tasks. Use it as a rapid revision tool to check your understanding and avoid costly mistakes in the exam.

在 IGCSE CIE 德语中,掌握这门语言就像解答一系列方程。正如数学有公式和定理,德语语法也依赖于固定模式、语序规则、格词尾和永不改变的动词结构。这本速查手册将德语的核心构件重新表述为“公式”和“定理”——清晰、可靠的规则,你可以背诵并在写作、口语、听力和阅读任务中直接套用。把它当作快速复习工具,用来检查理解、避免考试中代价高昂的错误。

1. Formula 1: The Verb-Second Theorem | 公式1:动词第二位定理

In a main clause (Hauptsatz), the conjugated verb always stands in position 2. The first position can be the subject, an adverb, an object, or any other element, but the verb must follow immediately. This rule is non-negotiable.

在主句(Hauptsatz)中,变位动词永远占据第二位。第一位可以是主语、副词、宾语或任何其他成分,但动词必须紧随其后。这条规则不容更改。

Formula: [Element 1] + [Conjugated Verb] + [Subject] + [Rest].

公式:[成分1] + [变位动词] + [主语] + [其余部分]。

Example: Morgen gehe ich ins Kino. (Tomorrow I am going to the cinema.) Here 'Morgen' takes position 1, 'gehe' is position 2, and 'ich' is the subject immediately after the verb.

示例:Morgen gehe ich ins Kino.(明天我去电影院。)这里“Morgen”占第一位,“gehe”是第二位,主语“ich”紧跟在动词之后。

Inversion occurs when the first element is not the subject. Compare: Ich gehe morgen ins Kino. (Subject first, then verb) vs. Morgen gehe ich ins Kino. (Adverb first triggers inversion of subject).

当第一位不是主语时发生倒装。对比:Ich gehe morgen ins Kino.(主语在先,然后动词)与 Morgen gehe ich ins Kino.(副词在先引起主语倒装)。


2. Formula 2: The Bracket Structure with Modal Verbs | 公式2:情态动词的框形结构

When a modal verb (dürfen, können, mögen, müssen, sollen, wollen) is used, the conjugated modal verb takes position 2, and the main verb in the infinitive moves to the end of the clause. This creates a 'verbal bracket' around the rest of the sentence.

当使用情态动词(dürfen, können, mögen, müssen, sollen, wollen)时,变位的情态动词占据第二位,主要动词的不定式移至从句末尾。这在句子其余部分周围形成一个“动词框架”。

Formula: [Subject/Element 1] + [Modal Verb (conjugated)] + [Middle Field] + [Main Verb (infinitive)].

公式:[主语/成分1] + [情态动词(变位)] + [中间场] + [主要动词(不定式)]。

Example: Ich muss morgen früh aufstehen. (I must get up early tomorrow.) 'muss' is in position 2, 'aufstehen' at the end. All other information (morgen früh) lies between the two verb parts.

示例:Ich muss morgen früh aufstehen.(我明天必须早起。)“muss”在第二位,“aufstehen”在末尾。所有其他信息(morgen früh)都位于两个动词部分之间。


3. Formula 3: The Subordinate Clause Word Order Theorem | 公式3:从句语序定理

In a subordinate clause (Nebensatz), the conjugated verb is pushed to the very end. The clause is introduced by a subordinating conjunction (e.g., dass, weil, obwohl, wenn, als). The verb appears after all other elements, including separable prefixes and infinitives.

在从句(Nebensatz)中,变位动词被推至最末端。从句由从属连词(如 dass, weil, obwohl, wenn, als)引导。动词出现在所有其他成分之后,包括可分离前缀和不定式。

Formula: [Conjunction] + [Subject] + [Middle Field] + [Verb (conjugated)] + [Verb (infinitive/participle)].

公式:[连词] + [主语] + [中间场] + [动词(变位)] + [动词(不定式/分词)]。

Example: Ich bleibe zu Hause, weil ich krank bin. (I'm staying at home because I am ill.) 'weil' sends the conjugated verb 'bin' to the end.

示例:Ich bleibe zu Hause, weil ich krank bin.(我待在家里,因为我生病了。)“weil”将变位动词“bin”送到句末。


4. Formula 4: Separable Verbs – Prefix Jump Theorem | 公式4:可分离动词——前缀分离定理

In a main clause, the separable prefix (e.g., auf-, an-, mit-, zu-) separates from the verb and goes to the end of the clause, while the verb stem stays in position 2. In a subordinate clause, the prefix reattaches to the verb at the end.

在主句中,可分离前缀(如 auf-, an-, mit-, zu-)从动词上分离并移到从句末尾,而动词词干保持在第二位。在从句中,前缀重新与动词结合在从句末尾。

Formula for main clause: [Prefix-stem] position 2 ... [prefix]. Example: Ich stehe um 7 Uhr auf. (I get up at 7 o'clock.) 'auf' separates and goes to the end.

主句公式:[前缀-词干] 第二位 ... [前缀]。示例:Ich stehe um 7 Uhr auf.(我7点起床。)“auf”分离并移到末尾。

Formula for subordinate clause: [Conjunction] ... [prefix+stem (conjugated)]. Example: ..., weil ich um 7 Uhr aufstehe. The prefix and verb reunite.

从句公式:[连词] ... [前缀+词干(变位)]。示例:..., weil ich um 7 Uhr aufstehe.(……因为我7点起床。)前缀和动词重新组合。


5. Formula 5: The Four Case Definite Article Table | 公式5:四格定冠词一览表

The definite article changes according to gender (masculine, feminine, neuter) and case (nominative, accusative, dative, genitive). This is a fundamental 'look-up table' for all adjective and pronoun endings.

定冠词根据性(阳、阴、中)和格(主格、宾格、与格、属格)变化。这是所有形容词和代词词尾的基础“查询表”。

Case / 格Masculine / 阳Feminine / 阴Neuter / 中Plural / 复
Nominative / 主格derdiedasdie
Accusative / 宾格dendiedasdie
Dative / 与格demderdemden (+n on noun)
Genitive / 属格des (+s/es on noun)derdes (+s/es on noun)der

Memorise this table as a single formula. All relative and demonstrative pronouns, as well as adjective endings, are derived from these forms.

将此表作为单一公式背诵。所有关系代词、指示代词以及形容词词尾都由此衍生。


6. Formula 6: Adjective Declension – Three Tables Theorem | 公式6:形容词变格——三表定理

Adjective endings depend on whether the article is definite (der-word), indefinite (ein-word), or there is no article at all. These three scenarios produce distinct but predictable ending patterns.

形容词词尾取决于冠词是定冠词类(der词)、不定冠词类(ein词)还是没有冠词。这三种情景产生不同但可预测的词尾模式。

After definite article: Adjective endings are -e or -en only. Nominative singular: -e for all genders; accusative feminine/neuter -e; all plurals and dative/genitive take -en.

定冠词后:形容词词尾仅为 -e 或 -en。主格单数:所有性为 -e;宾格阴/中为 -e;所有复数及与格/属格为 -en。

After indefinite article (and kein, possessives): The adjective carries the gender/case marker that the definite article would have had. e.g., ein guter Mann (nom. masc., like 'der'), einen guten Mann (acc. masc.).

不定冠词后(及 kein、物主代词):形容词承载定冠词原本应具有的性/格标记。例如:ein guter Mann(主格阳,像“der”),einen guten Mann(宾格阳)。

No article (zero article): The adjective takes the same ending as the definite article, except masculine and neuter genitive, which are -en instead of -es. Example: kaltes Wasser (nom./acc. neuter, like 'das').

无冠词:形容词词尾与定冠词相同,但阳性和中性属格为 -en 而非 -es。示例:kaltes Wasser(主/宾中,像“das”)。

7. Formula 7: The Perfect Tense Construction Theorem | 公式7:现在完成时结构定理

The perfect tense is formed with haben or sein (conjugated in present) + past participle (ge-...-t/-en). The auxiliary verb is in position 2, and the past participle is at the end of the clause. Sein is used for verbs indicating movement from A to B or a change of state.

现在完成时由 haben 或 sein(现在时变位) + 过去分词(ge-...-t/-en)构成。助动词在第二位,过去分词在从句末尾。sein 用于表示从 A 到 B 的移动或状态变化的动词。

Formula: [Subject/Element 1] + [haben/sein (conjugated)] + [...] + [past participle].

公式:[主语/成分1] + [haben/sein(变位)] + [...] + [过去分词]。

Example with haben: Ich habe gestern einen Film gesehen. (I saw a film yesterday.)

haben 示例:Ich habe gestern einen Film gesehen.(我昨天看了一部电影。)

Example with sein: Er ist nach Berlin gefahren. (He went to Berlin.)

sein 示例:Er ist nach Berlin gefahren.(他去了柏林。)


8. Formula 8: The Future and Conditional 'werden' Formulas | 公式8:将来时与条件式“werden”公式

Future tense uses werden (conjugated in position 2) + infinitive at the end. The conditional (Konjunktiv II with würde) uses würde (conjugated) + infinitive at the end. Both follow the same bracket pattern.

将来时使用 werden(在第二位变位)+ 不定式在末尾。条件式(虚拟二式用 würde)使用 würde(变位)+ 不定式在末尾。两者都遵循相同的框架模式。

Future: Ich werde morgen ins Kino gehen. (I will go to the cinema tomorrow.)

将来时:Ich werde morgen ins Kino gehen.(我明天将去电影院。)

Conditional with würde: Ich würde gern ins Kino gehen. (I would like to go to the cinema.)

条件式用 würde:Ich würde gern ins Kino gehen.(我很想去电影院。)


9. Formula 9: The Preposition-Case Binding Theorems | 公式9:介词-格绑定定理

Certain prepositions always take a specific case. Others (two-way prepositions) take accusative for direction (wohin?) and dative for location (wo?). This is a critical pattern for article and adjective endings.

某些介词总是支配特定格。另一些(双向介词)当表示方向(wohin?)时支配宾格,表示位置(wo?)时支配与格。这是冠词和形容词词尾的关键模式。

Always dative prepositions: aus, bei, mit, nach, seit, von, zu. Formula: [preposition] + [dative]. mit dem Auto.

永远支配与格的介词:aus, bei, mit, nach, seit, von, zu。公式:[介词] + [与格]。mit dem Auto。

Always accusative prepositions: durch, für, gegen, ohne, um. Formula: [preposition] + [accusative]. für den Freund.

永远支配宾格的介词:durch, für, gegen, ohne, um。公式:[介词] + [宾格]。für den Freund。

Two-way (Wechselpräpositionen): an, auf, hinter, in, neben, über, unter, vor, zwischen. Accusative when movement: in die Schule (into the school); dative when static: in der Schule (in the school).

双向介词:an, auf, hinter, in, neben, über, unter, vor, zwischen。移动时用宾格:in die Schule(进入学校);静态时用与格:in der Schule(在学校里)。


10. Formula 10: The 'es gibt' and 'man' Impersonal Formulas | 公式10:无人称结构“es gibt”与“man”公式

The expression es gibt (there is/are) always takes the accusative case. It is an unchanging block – es is the fixed subject, gibt is the verb, and the object is in accusative regardless of number or gender.

表达 es gibt(有)永远支配宾格。这是一个不变的结构块——es 是固定主语,gibt 是动词,宾语始终用宾格,不限数量或性。

Example: Es gibt einen großen Park in der Stadt. (There is a big park in the city.) 'einen großen Park' is accusative.

示例:Es gibt einen großen Park in der Stadt.(城里有一个大公园。)“einen großen Park”是宾格。

The indefinite pronoun man (one/you/people) is used to make general statements. It always takes the 3rd person singular verb form. In accusative it becomes einen, dative einem.

不定代词 man(人们/有人)用于一般陈述。永用第三人称单数动词形式。宾格变为 einen,与格 einem。

Example: Man muss im Unterricht aufpassen. (One must pay attention in class.) Das macht einen müde. (That makes you tired.)

示例:Man muss im Unterricht aufpassen.(课堂上要专心。)Das macht einen müde.(那使人疲惫。)


11. Formula 11: The Comparative and Superlative Patterns | 公式11:比较级与最高级模式

rlatives by adding -(e)st. Umlaut often occurs with common single-syllable adjectives (a → ä, o → ö, u → ü oun, it takes the normal adjective ending on top of the comparative or superlative marker.

比较级在形容词后加 -er 构成,最高级加 -(e)st。常见单音节形容词常发生变音(a → ä, o → ö, u → ü)。当形容词位于名词前时,它在比较级或最高级标记之上再接正常形容词词尾。

Formula: schnell → schneller → am schnellsten (fast → faster → fastest). For attributive use: der schnellere Zug (the faster train), der schnellste Zug (the fastest train).

公式:schnell → schneller → am schnellsten(快的→更快→最快)。作定语时:der schnellere Zug(较快的火车),der schnellste Zug(最快的火车)。

Irregular forms like gut – besser – am besten and gern – lieber – am liebsten must be memorised.

不规则形式如 gut – besser – am besten 和 gern – lieber – am liebsten 必须牢记。


12. Formula 12: The Relative Pronoun Chord Theorem | 公式12:关系代词协调定理

Relative pronouns (der, die, das) agree in gender and number with the noun they refer to, but their case is determined by their function within the relative clause. This dual dependency is a common exam pitfall.

关系代词(der, die, das)的性和数与其所指名词一致,但它们的格由其在关系从句中的功能决定。这种双重依赖是考试中的常见陷阱。

Example: Der Mann, der dort steht, ist mein Onkel. (The man who is standing there is my uncle.) 'der' is masculine singular nominative because it is the subject of 'steht'.

示例:Der Mann, der dort steht, ist mein Onkel.(站在那里的男人是我叔叔。)“der”是阳性单数主格,因为它是“steht”的主语。

Contrast: Der Mann, den ich sehe, ist mein Onkel. (The man whom I see is my uncle.) Here 'den' is masculine singular accusative because it is the direct object of 'sehe'.

对比:Der Mann, den ich sehe, ist mein Onkel.(我看见的那个男人是我叔叔。)这里“den”是阳性单数宾格,因为它是“sehe”的直接宾语。

Relative pronouns after prepositions: The case required by the preposition overrides the case of the antecedent. Das Haus, in dem ich wohne... (The house in which I live – 'in' takes dative.)

介词后的关系代词:介词所要求的格凌驾于先行词的格之上。Das Haus, in dem ich wohne...(我住的那个房子——'in' 支配与格。)
