From verb positions to case endings, you will find quick references that make revision simple and effective.
德语语法就像一套复杂的方程式，但只要你掌握了核心“公式”，一切就会豁然开朗。本手册专为八年级Edexcel学习者设计，将基本规则浓缩为清晰的双语解释。从动词位置到格词尾，你都能找到让复习变得简单高效的速查要点。
1. The Verb-Second Rule (V2) | 动词二位法则
In a main clause, the conjugated verb always sits in the second position. This does not mean it is the second word; it means it is the second idea or element. The first position can be the subject, an adverb, a time phrase, or even an object, but the verb never moves from place two.
在主句中，变位动词总是位于第二位。这并不意味着它是第二个单词，而是第二个句子成分。第一位可以是主语、副词、时间短语甚至宾语，但动词始终坚守在第二位。
- Ich spiele am Samstag Fußball. (Subject first)
- Am Samstag spiele ich Fußball. (Time phrase first, verb still second)
Position 1 + Verb + Subject + Rest
位置1 + 动词 + 主语 + 其余部分
2. The Time-Manner-Place Order | 时间-方式-地点顺序
When you add extra details to a sentence, German prefers the sequence: Time (wann?), Manner (wie?), Place (wo?). This TEMAP formula helps you sound more natural and avoid word order mistakes. Adverbs of time usually come before adverbs of manner and place.
当你为句子添加额外细节时，德语倾向于采用时间、方式、地点的顺序。这个“时方地”公式能帮你听起来更自然，并避免语序错误。时间副词通常先于方式和地点副词出现。
| Time | Manner | Place |
| am Wochenende | mit Freunden | im Park |
| morgens | laut | in der Küche |
Example: Ich gehe am Wochenende (Time) mit Freunden (Manner) ins Kino (Place).
例句：我周末（时间）和朋友（方式）去电影院（地点）。
3. Question Words as Formulas | 疑问词公式
Every question word in German starts with a ‘W’ and acts like a formula to request specific information. Learning these as fixed chunks with the word order that follows makes forming questions automatic. Remember: question word + conjugated verb + subject + rest.
德语中每个疑问词都以“W”开头，就像请求特定信息的公式。将这些疑问词与随后的语序作为一个固定模块来学习，能让提问变得自动化。记住：疑问词 + 变位动词 + 主语 + 其余部分。
- Wer bist du? (Who)
- Was machst du? (What)
- Wo wohnst du? (Where)
- Wann kommst du? (When)
- Warum lernst du Deutsch? (Why)
- Wie geht es dir? (How)
4. Yes/No Question Inversion | 是非疑问句倒装
To turn a statement into a yes/no question, simply swap the subject and the conjugated verb. The verb moves to position one, followed immediately by the subject. This ‘inversion formula’ is one of the simplest yet most powerful structures in German.
要将陈述句变为是非疑问句，只需交换主语和变位动词的位置。动词移到第一位，紧接着是主语。这个“倒装公式”是德语中最简单但又最强大的结构之一。
Statement: Du spielst Tennis. → Question: Spielst du Tennis?
陈述句：你打网球。→ 问句：你打网球吗？
This formula works for all tenses. In the perfect tense, only the auxiliary verb (haben/sein) moves: Du hast gegessen. → Hast du gegessen?
这个公式适用于所有时态。在完成时中，只有助动词（haben/sein）移动：你吃过了。→ 你吃过了吗？
5. Negation with ‘nicht’ Positioning | “nicht”的否定位置公式
The word ‘nicht’ follows a clear positioning rule. It goes at the end of the sentence if you are negating the entire verb or action. However, if you are negating a specific part (like a time, place, or adjective), ‘nicht’ goes directly before that element.
“nicht”一词遵循明确的位置规则。如果否定整个动词或动作，它位于句末。但如果否定句子的某个特定部分（如时间、地点或形容词），“nicht”则直接放在该部分之前。
- Ich verstehe das nicht. (Negating the whole action — at the end)
- Ich komme nicht am Montag, sondern am Dienstag. (Negating the time — before it)
- Das ist nicht gut. (Negating the adjective — before it)
6. The Case System: Nominative, Accusative, Dative | 格系统：主格、宾格、与格
German uses four cases to show the function of nouns and pronouns. Year 8 focuses on the first three. Think of them as identification tags: Nominative = subject (doer), Accusative = direct object (receiver of action), Dative = indirect object (to/for whom).
德语用四个格来表示名词和代词的功能。八年级重点学习前三个。可以把它们看作识别标签：主格 = 主语（动作执行者），宾格 = 直接宾语（动作接收者），与格 = 间接宾语（给谁/为谁）。
| Case | Masculine (der) | Feminine (die) | Neuter (das) | Plural (die) |
| Nominative | der | die | das | die |
| Accusative | den | die | das | die |
| Dative | dem | der | dem | den (+n on noun) |
7. Personal Pronouns in Three Cases | 三个格中的人称代词
Pronouns change their form depending on the case they are in. Memorising the pronoun patterns is like learning the multiplication tables of German grammar — once you know them, everything else becomes faster.
代词的形式取决于它们所处的格。记住代词的模式就像学习德语语法的乘法表——一旦掌握，其他一切都变得更快。
| English | Nominative | Accusative | Dative |
| I | ich | mich | mir |
| you (informal) | du | dich | dir |
| he | er | ihn | ihm |
| she | sie | sie | ihr |
| it | es | es | ihm |
| we | wir | uns | uns |
| they / you (formal) | sie / Sie | sie / Sie | ihnen / Ihnen |
Example: Der Lehrer gibt dem Schüler (dative) das Buch (accusative). → Der Lehrer gibt es ihm.
例句：老师给了那个学生（与格）那本书（宾格）。→ 老师把它给了他。
8. Article and Adjective Endings After ‘der-/ein-‘ Words | 定冠词/不定冠词后的形容词词尾
After a definite article (der/die/das), the adjective usually takes an -e or -en ending. After an indefinite article (ein/eine/ein), the adjective carries the strong ending to show the case. This ‘ending rule formula’ ensures that the noun’s gender and case are always marked somewhere.
在定冠词（der/die/das）之后，形容词通常以-e或-en结尾。在不定冠词（ein/eine/ein）之后，形容词承担强变化词尾来显示格。这条“词尾规则公式”确保名词的性和格总能在某个地方被标记出来。
After der: der große Hund (Nom.), den großen Hund (Acc.)
After ein: ein großer Hund (Nom.), einen großen Hund (Acc.)
The core rule: if the article does not clearly show the case (like ein in nominative masculine), the adjective must show it. If the article already shows it (dem, den), the adjective defaults to -en.
核心规则：如果冠词没有清楚地展示格（如阳性主格的ein），形容词就必须展示出来。如果冠词已经展示了（dem, den），形容词默认为-en。
9. Modal Verbs: The Conveyor Belt Formula | 情态动词：传送带公式
Modal verbs (können, müssen, wollen, dürfen, sollen, mögen) modify the meaning of a main verb. The formula is simple: the modal verb is conjugated and placed in position 2, while the main verb goes to the end of the sentence in its infinitive form. Think of the modal verb as pulling the main verb all the way to the back.
情态动词（能、必须、想要、被允许、应该、喜欢）修饰主动词的含义。公式很简单：情态动词变位并放在第二位，而主动词以不定式形式位于句末。可以想象情态动词把主动词一路拉到句子末尾。
Subject + Modal Verb + … + Infinitive (at the end)
主语 + 情态动词 + … + 不定式（在末尾）
- Ich kann gut schwimmen.
- Wir müssen morgen früh aufstehen.
- Sie will ein Eis essen.
10. The Perfect Tense Formula | 完成时公式
To talk about the past in spoken German, the perfect tense is essential. It is made up of two parts: an auxiliary verb (haben or sein) in position 2, and a past participle at the end of the sentence. The choice between haben and sein follows a movement/change of state rule.
在德语口语中谈论过去时，完成时至关重要。它由两部分组成：位于第二位的助动词（haben或sein）和位于句末的过去分词。haben和sein的选择遵循移动/状态变化规则。
haben/sein + … + past participle (ge…t/en)
haben/sein + … + 过去分词（ge…t/en）
Most verbs use haben. Verbs indicating movement from A to B (gehen, fahren, fliegen) or a change of state (aufwachen, einschlafen) use sein. Past participles of regular verbs end in -t (gespielt), irregular ones often end in -en (gegangen, gegessen).
大多数动词用haben。表示从A到B的移动（走、乘车、飞行）或状态变化（醒来、入睡）的动词用sein。规则动词的过去分词以-t结尾（gespielt），不规则动词常以-en结尾（gegangen, gegessen）。
11. The Subordinating Conjunction ‘Verb-Kicker’ | 从属连词“动词踢到末尾”公式
Words like weil (because), dass (that), wenn (when/if), and obwohl (although) send the conjugated verb to the very end of the clause. This is a hard rule: no matter what, the verb leaves position 2 and moves to the final slot in a subordinate clause.
像weil（因为）、dass（引导宾语从句）、wenn（当/如果）和obwohl（尽管）这样的词会将变位动词踢到从句的最末尾。这是一条硬性规则：无论什么情况，动词都会离开第二位，移到从句的最终位置。
Main clause + Subordinating conjunction + Subject + … + Verb (end)
主句 + 从属连词 + 主语 + … + 动词（末尾）
Example: Ich bleibe zu Hause, weil ich krank bin. (Note: bin moves to the end.)
例句：我待在家里，因为我病了。（注意：bin移到了末尾。）
12. Prepositions and Their Case Partners | 介词及其格搭档
Prepositions are like traffic lights: they dictate which case follows. Some go with accusative (durch, für, gegen, ohne, um), some with dative (aus, bei, mit, nach, seit, von, zu), and some are two-way (in, an, auf, hinter, neben, unter, über, vor, zwischen). The two-way prepositions take accusative for motion (wohin?), and dative for location (wo?).
介词就像交通信号灯：它们决定后面跟什么格。有些与宾格搭配（durch, für, gegen, ohne, um），有些与与格搭配（aus, bei, mit, nach, seit, von, zu），还有一些是二维介词（in, an, auf, hinter, neben, unter, über, vor, zwischen）。二维介词在表示移动（wohin?）时用宾格，表示位置（wo?）时用与格。
Motion → Accusative: Ich gehe in die Schule. (I go into the school.)
移动 → 宾格：我走进学校。
Location → Dative: Ich bin in der Schule. (I am in the school.)
位置 → 与格：我在学校里。
