Passiv mit Modalverben: Dinge erledigen
Grammar Rule in 30 Seconds
Use modal passives to focus on the action's necessity or possibility without needing to mention who is performing it.
- Present/Future: Use 'Modal + be + Past Participle' (e.g., 'It must be finished').
- Past: Use 'Modal + have been + Past Participle' (e.g., 'It should have been done').
- Negative: Place 'not' after the modal (e.g., 'It cannot be changed').
Overview
We must finish the project.can, must, should, might, etc.) ist eines der elegantesten Werkzeuge der englischen Sprache. Es erlaubt dir, den Fokus weg von der handelnden Person (dem Agens) hin zur Handlung selbst oder dem Empfänger der Handlung zu verschieben. Warum ist das wichtig?The report must be submitted by Friday. Das klingt objektiv, professionell und rückt die Deadline in den Mittelpunkt, nicht die Person, die unter Druck gesetzt wird.can, could, may, might, must, shall, should, will, would) immer der Infinitiv ohne to (der sogenannte *bare infinitive*).The manager (Subject) must (Modal) sign (Infinitive) the contract (Object).be. Danach folgt das *Past Participle* (die 3. Verbform) des Hauptverbs.become. Aber Achtung: become bedeutet im Englischen „etwas werden“ im Sinne einer Entwicklung (z.B.to become a doctor). Im Passiv ist das Hilfsverb im Englischen immer eine Form von be.be verändern sich nicht, egal ob das Subjekt Singular oder Plural ist. Im Deutschen müssen wir konjugieren: „Das Dokument muss gelesen werden“ vs. „Die Dokumente müssen gelesen werden“.The document must be read / The documents must be read. Die Komplexität des deutschen Kasussystems (Nominativ, Genitiv, Dativ, Akkusativ) fällt hier komplett weg, was dir erlaubt, dich voll und ganz auf die Bedeutung des Modalverbs zu konzentrieren.Subject + Modal Verb + be + Past Participle (V3)must | Starke Notwendigkeit | You must lock the door. | The door must be locked. |should | Ratschlag / Empfehlung | We should inform the staff. | The staff should be informed. |can | Möglichkeit / Fähigkeit | They can solve the problem. | The problem can be solved. |might | Vage Möglichkeit | Someone might steal the car. | The car might be stolen. |will | Zukunft / Versprechen | The company will launch the app. | The app will be launched. |not wird direkt hinter das Modalverb gesetzt. Oft werden hier Kontraktionen verwendet (außer in sehr formalen Texten).- Formel:
Subject + Modal Verb + not + be + Past Participle - Beispiel:
The files must not be deleted.(Die Dateien dürfen nicht gelöscht werden.) - Beispiel:
The meeting couldn't be cancelled.(Das Meeting konnte nicht abgesagt werden.)
be + Past Participle bleibt als Block zusammen am Ende (bzw. nach dem Subjekt).- Formel:
Modal Verb + Subject + be + Past Participle? - Beispiel:
Can the deadline be extended?(Kann die Frist verlängert werden?) - Beispiel:
Should the office be cleaned today?(Sollte das Büro heute gereinigt werden?)
to brauchen, wie have to oder ought to. Hier bleibt das to erhalten:The car has to be repaired.(Das Auto muss repariert werden.)The rules ought to be followed.(Die Regeln sollten befolgt werden.)
- *Szenario:* Eine interne Revision im Unternehmen.
- *Satz:*
All financial records must be kept for ten years. - *Warum:* Es ist egal, *wer* sie aufbewahrt; wichtig ist die gesetzliche Vorschrift für das Objekt (die Unterlagen).
You must fix this mistake, klingt das nach einer Standpauke. Nutzt du das Passiv, kritisierst du die Sache, nicht die Person.- *Szenario:* Feedback zu einem Entwurf.
- *Satz:*
Some minor errors could be corrected in the final version. - *Warum:* Das klingt nach einem hilfreichen Hinweis statt nach einer direkten Zurechtweisung.
- *Szenario:* Du kommst in deine WG und siehst, dass die Fenster geputzt wurden.
- *Satz:*
The windows must have been cleaned this morning.(Hier nutzen wir sogar das Perfect Passive, aber das Prinzip bleibt gleich: Das Ergebnis zählt). - *Szenario:* Eine Durchsage am Bahnhof.
- *Satz:*
Luggage should not be left unattended.
- *Szenario:* Sicherheitseinweisung im Flugzeug.
- *Satz:*
Electronic devices may be used in flight mode. - *Szenario:* Mietvertrag für eine Wohnung.
- *Satz:*
The rent must be paid by the third of each month.
- *Szenario:* Brainstorming in der Uni.
- *Satz:*
The energy crisis might be solved through nuclear fusion.
- Falsch:
The work must become done. - Richtig:
The work must be done. - Erklärung: Im Englischen ist
becomeeine Zustandsveränderung (I became tired), kein Passiv-Hilfsverb. Merke dir: Passiv =be.
be untergeht.- Falsch:
The report must finished. - Richtig:
The report must be finished. - Erklärung: Ohne
befehlt das Bindeglied, das den Satz zum Passiv macht.must finishedergibt im Englischen grammatikalisch keinen Sinn.
be zu konjugieren, weil sie das Subjekt (z.B. the report = it) im Kopf haben.- Falsch:
The report must is finished. - Richtig:
The report must be finished. - Erklärung: Nach einem Modalverb steht immer der Infinitiv. Die Formen
is,are,am,was,weresind konjugierte Formen und haben nachmust,can,shouldetc. nichts zu suchen.
- Wenn du sagst
The task must not be done, bedeutet das im Englischen: „Die Aufgabe darf nicht gemacht werden“ (Verbot). - Wenn du meinst „Die Aufgabe muss nicht gemacht werden“ (Freiwilligkeit), musst du sagen:
The task doesn't have to be done. - L1-Interferenz: Im Deutschen ist „nicht müssen“ oft schwächer als im Englischen „must not“.
- Falsch:
The letter should be wrote. - Richtig:
The letter should be written.
We should update the software. | Fokus auf der Gruppe („Wir“). Direkt, handlungsorientiert. |The software is updated. | Reine Zustandsbeschreibung oder regelmäßige Handlung. |The software should be updated. | Fokus auf der Notwendigkeit/Empfehlung. Höflicher, professioneller. |The software should get updated. | Eher umgangssprachlich. „Get“ ersetzt hier „be“. Nicht für formale Berichte geeignet. |one (One should update...), aber das klingt oft extrem steif und veraltet. Das Passiv mit Modalverben ist die modernere und natürlichere Art, das deutsche „man“ in einem professionellen Kontext zu ersetzen.- Deutsch: „Man muss hier vorsichtig sein.“
- Englisch (steif):
One must be careful here. - Englisch (natürlich/Passiv):
Caution must be exercised here.
The car should get repaired ist völlig korrektes Englisch, klingt aber sehr nach Alltagssprache (Stammtisch oder WhatsApp-Chat). In einer Uni-Hausarbeit oder einer geschäftlichen E-Mail an einen Kunden solltest du unbedingt bei be bleiben.Modal + have been + V3.The bridge should have been built years ago. (Die Brücke hätte vor Jahren gebaut werden sollen). Hier kombinierst du das Modalverb mit dem Perfect Passive.must, should, can, could, will und might am häufigsten. May wird oft in formalen Erlaubnissen genutzt (This area may be accessed by authorized personnel only).My boss must make the decision. Wenn du aber sagen willst, dass die Entscheidung generell ansteht, ist The decision must be made die bessere Wahl. Es geht immer um den Kontext!Modal Passive Formation

FAQ (8)
Yes, in informal English. For example, 'It needs to get done' instead of 'It needs to be done'. However, 'be' is much more common in writing.
'Must not be' is for rules (prohibition), while 'cannot be' is for things that are impossible.
Use the word `by` at the end. 'The law must be signed `by the President`.'
Yes, they are almost identical in meaning, but 'ought to' is slightly more formal or moralistic.
Technically yes (modal passive continuous), but it is very rare and usually replaced by simpler forms like 'might be happening'.
To sound objective. Scientists care about the experiment, not the person holding the test tube. 'The liquid must be heated' sounds more scientific than 'I must heat the liquid'.
No, you are missing the word `have`. It must be 'It should `have` been done'.
When the 'doer' of the action is the most important part of the sentence or when you want to be very direct and personal.
